In general, embodiments of the invention relate to systems, devices, and methods for managing electromagnetic interference in a high-density environment. Specifically, embodiments of the invention may provide a system that manages electromagnetic interference at a data processing device level. By doing so, embodiments of the invention may facilitate the inclusion of electromagnetic interference emitting devices in a high-density environment while mitigating the impact of electromagnetic interference generated by the electromagnetic interference emitting devices.
In one or more embodiments of the invention, a data processing device includes an optical state detector. The optical state detector may enable optical states of devices disposed in a data processing device to be determined while the electromagnetic interference generated by such devices is contained within the data processing device. The optical states may be used to improve the accuracy of operational state determinations of the data processing devices when compared to determination of operational states made without optical state information for the devices.
In one or more embodiments of the invention, the operational states of the devices disposed in the data processing device is used to determine future actions to be performed by the devices. For example, the operational states of the devices may be used to determine whether to repeatedly invoke functionality of the devices or to invoke different functionalities of the devices. The operational states of the devices may be used for other purposes without departing from the invention.
For example, one or more electromagnetic interference emitting devices may be disposed within one or more of the data processing devices (102). The system illustrated in
To do so, the system of
For example, a data processing device in accordance with embodiments of the invention may provide greater than 35 decibels of isolation, between 35-50 decibels of isolation, between 50-65 decibels of isolation, between 65-80 decibels of isolation, and/or greater than 80 decibels of isolation.
The electromagnetic interference isolation provided by the data processing devices (102) may have a frequency dependent response. For example, the data processing devices (102) may provide at least 90 decibels (dB), or another suitable level of isolation, across a frequency band in which devices that may be disposed within the data processing devices (102) are adapted to emit electromagnetic interference. In other frequency bands, the data processing devices (102) may provide different level or no electromagnetic interference isolation for devices disposed within the data processing devices (102).
Accordingly, a data processing device in accordance with one or more embodiments of the invention may provide electromagnetic interference suppression services that are frequency dependent. In one or more embodiments of the invention, a data processing device provides electromagnetic interference isolation by reducing the strength of electromagnetic interference across at least one frequency band by a predetermined amount (e.g., 90 decibels).
An electromagnetic interference emitting device may be any type of hardware device that intentionally emits electromagnetic radiation as part of its operation. The emissions of electromagnetic radiation may be, for example, continuous, periodic, or intermittent (e.g., at any point in time based on the operation of the respective electromagnetic interference emitting device). An electromagnetic interference emitting device may be, for example, a personal electronic device such as a cellular device (e.g., smart phone, cell phone, etc.), a personal computer (e.g., any type of computing device with wireless communication capabilities such as a tablet computer, a laptop computer, etc.), a watch (e.g., a wireless smart watch), or any other type of hardware device that intentionally emits electromagnetic radiation for any purpose (e.g., communications, detection, etc.).
The electromagnetic interference emitted by an electromagnetic interference emitting device may be frequency dependent. That is, the electromagnetic interference emitted by the electromagnetic interference emitting device may be stronger in a first frequency band and weaker in a second frequency band. To provide electromagnetic interference suppression services, a data processing device in accordance with one or more embodiments of the invention may attenuate the electromagnetic interference emitted by an electromagnetic interference emitting device by at least a predetermined amount (e.g., 80 decibels) across at least one frequency band in which the electromagnetic interference emitting device emits electromagnetic interference. The at least one frequency band may be, for example, the frequency band in which the emitted electromagnetic interference has a largest magnitude.
In one or more embodiments of the invention, an electromagnetic interference emitting device emits electromagnetic interference having frequency content between 700 megahertz and 10 gigahertz. An electromagnetic interference emitting device may emit electromagnetic interference having different frequency content without departing from the invention.
Additionally, the example system of
To further discuss aspects of embodiments of the disclosed technology, each component of the system of
In one or more embodiments of the invention; the frame (100) is a physical structure. The physical structure may be adapted to facilitate storage of the data processing devices (102) in a high-density computing environment. The high-density computing environment may be, for example, a data center or another type of location where multiple data processing devices are located. To facilitate storage of the data processing devices (102), the frame (100) may include any number of structural members (e.g., beams, brackets, bars, etc.) and any number of mechanical mounting points (e.g., holes, threaded portions, etc.) disposed on the structural members to facilitate storage of the data processing devices (102).
Different structural members may have different shapes, sizes, and/or other physical characteristics. The shapes, sizes, and/or other physical characteristics of the structural members may be adapted to enable the structural members to be mechanically connected (e.g., permanently or reversibly connected) to each other to form a predetermined structure. The predetermined structure may be, for example, a cage, box, or other type of structure that facilitates positioning and/or orienting the data processing devices (102).
When all, or a portion, of the structural members are mechanically connected to each other, the mechanical mounting points may be disposed at predetermined locations. The predetermined locations may correspond to similar predetermination locations on the data processing devices (102) where mechanical mounting elements, complementary to the mechanical mounting point, are disposed. By doing so, the frame (100) and the data processing devices (102) may be adapted to position the data processing devices (102) in locations and/or orientations compatible with a high-density computing environment, or another environment in which the data processing devices (102) may be located.
The mechanical mounting points may be any type of physical structure for attaching (permanently or reversibly) the data processing devices (102) to the frame (100). There may be any number of mechanical mounting points to facilitate the attachment of any number of data processing devices.
The frame (100) may be implemented using any number of suitable materials. For example, portions of the frame (100) may be implemented using metals (e.g., steel, aluminum, etc.). In another example, portions of the frame (100) may be implemented using polymers (e.g., Polyamides, polycarbonates, polyester, polyethylene, polypropylene, polystyrene, polyurethanes, polyvinyl chloride, polyvinylidene chloride, acrylonitriline butadiene styrene, etc.). In a still further example, portions of the frame (100) may be implemented using rubber (e.g., latex, styrene-butadiene rubbers, etc.) The frame (100) may be implemented using any quantity and combination of suitable materials without departing from the invention.
In one or more embodiments of the invention, the data processing devices (102) are physical structures. For example, the data processing devices (102) may include a chassis and one or more computing devices disposed within the chassis. For additional details regarding computing devices, refer to
A chassis may be a mechanical device that is adapted to (i) facilitate attachment of the data processing device to the frame, (ii) house the one or more computing devices, (iii) house one or more electromagnetic interference emitting devices, and/or (iv) provide thermal management services to the computing devices and/or the electromagnetic interference emitting devices. For example, a chassis may be a frame mountable structure (e.g., a rectangular box) that includes internal space that may be used to house computing devices and/or electromagnetic interference emitting devices. Thus, the chassis may be a frame mountable chassis.
The chassis may be implemented using any number of suitable materials. For example, portions of the chassis may be implemented using metals (e.g., steel, aluminum, etc.). In another example, portions of the chassis may be implemented using polymers (e.g., Polyamides, polycarbonates, polyester, polyethylene, polypropylene, polystyrene, polyurethanes, polyvinyl chloride, polyvinylidene chloride, acrylonitriline butadiene styrene, etc.). In a still further example, portions of the chassis may be implemented using rubber (e.g., latex, styrene-butadiene rubbers, etc.) The chassis may be implemented using any quantity and combination of suitable materials without departing from the invention.
To facilitate attachment of the data processing device to the frame, the chassis may include any number of mechanical mounting elements. The mechanical mounting elements may be located at predetermined locations. The predetermined locations may correspond to similar predetermination locations on the frame (100) where mechanical mounting points, complementary to the mechanical mounting elements, are disposed.
For example, a mechanical mounting element may be a rail disposed on a side of a chassis of a data processing device. The location of the rail may correspond to a position on the frame (100) where a rail guide (i.e., a complementary mechanical mounting point) is disposed. The rail and the rail guide may facilitate attachment of a data processing device to the frame (100) which, in turn, positions and orients the data processing device relative to the frame (100).
To house the one or more computing devices, the chassis may include one or more internal volumes. The internal volumes may facilitate disposing of the one or more computing devices (and/or other devices such as electromagnetic interference emitting devices) within a data processing device.
To house the one or more electromagnetic interference emitting devices, the chassis may include one or more internal volumes (e.g., separate and/or the same as the internal volumes for housing computing devices). The internal volumes may have a shape or other characteristic(s) that facilitates disposing of the one or more electromagnetic interference emitting devices within the data processing device. For example, an internal volume of the chassis may be a rectangular void capable of housing one or more electromagnetic interference emitting devices. The internal volume may have other shapes without departing from the invention.
In one or more embodiments of the invention, the one or more internal volumes of the data processing devices are adapted to restrict propagation of electromagnetic interference emitted by the electromagnetic interference emitting devices (and/or other devices such as computing devices). For example, one or more portions of the chassis that bound the one or more internal volumes may be made of metal of a predetermined thickness to prevent and/or limit transmission of electromagnetic interference through the one or more portions of the chassis. By doing so, the electromagnetic interference generated by the electromagnetic interference emitting devices may be prevented (or at least severely attenuated when leaving an internal volume) from propagating from within the data processing devices (102) into the ambient environment surrounding the respective data processing devices (102) (and/or restricted from propagating to other portions of the data processing devices).
In another example, one or more portions of the chassis that bound the one or more internal regions may be formed in a manner that filters (e.g., reflects/attenuates radiation of a certain frequency while allowing radiation of other frequencies to propagate) electromagnetic radiation when electromagnetic radiation passes through the portions of the chassis. For example, a portion of the chassis that bounds the one or more internal regions may be a waveguide filter such as an array of holes (e.g., sub-wavelength apertures corresponding to a particular frequency) in a metal sheet. By doing so, the electromagnetic interference generated by the electromagnetic interference emitting devices may be severely attenuated (e.g., attenuated by greater than 90 decibels) when propagating from within the data processing devices (102) into the ambient environment surrounding the respective data processing devices (102) (and/or restricted from propagating to other portions of the data processing devices).
In a further example, one or more portions of the chassis that bound the one or more internal regions may be made of an electromagnetic radiation attenuating material of a predetermined thickness to prevent and/or limit transmission of electromagnetic interference through the one or more portions of the chassis. The electromagnetic radiation attenuating material may be, for example, a composite of plastic or rubber that includes particulates of iron, carbonyl iron, or other electromagnetically lossy material. By doing so, the electromagnetic interference generated by the electromagnetic interference emitting devices may be severely attenuated (e.g., attenuated by greater than 90 decibels) when propagating from within the data processing devices (102) into the ambient environment surrounding the respective data processing devices (102) (and/or restricted from propagating to other portions of the data processing devices).
To provide thermal management services to the computing devices and/or the electromagnetic interference emitting devices and/or other types of devices, the data processing devices (102) may facilitate the flow of gas proximate to the computing devices and/or electromagnetic interference emitting devices. By doing so, the thermal state (i.e., temperature) of the aforementioned devices may be regulated. The gas may be air or another type/combination of gasses obtained from any source.
For example, a data processing device may include one or more vents that enable gas from a first side of a data processing device to flow into the data processing device, through the data processing device, and out of a second side of the data processing device. The gas, flowing through the data processing device, may be at a different temperature than the computing devices and/or electromagnetic interference emitting devices. Consequently, thermal exchange between the flow of gas and the aforementioned devices may occur resulting in the temperature of the aforementioned devices changing. By doing so, heat generated by the aforementioned devices may be expelled from the devices thereby regulating the temperature of the aforementioned devices.
A system in accordance with embodiments of the invention may include any number of data processing devices. Different data processing devices (102) may have different configurations and/or uses within the system.
For example, some data processing devices may be adapted to house many electromagnetic interference emitting devices while other data processing devices may be primarily adapted to house computing devices. Additional data processing devices may be adapted to exclusively house data processing devices and no electromagnetic interference emitting devices. A system in accordance with embodiments of the invention may include any number and combination of data processing devices adapted for any number of different uses without departing from the invention.
By way of example, the system of
For additional details regarding data processing devices, refer to
As discussed above, data processing devices (102) may house electromagnetic interference emitting devices. When so housed, the electromagnetic interference emitting devices may operate thereby generating electromagnetic interference (e.g., electromagnetic radiation). At different points in time, it may be useful to add or remove electromagnetic interference emitting devices to or from the data processing devices (102). To facilitate such additions and/or removals, different portions of the data processing devices (102) may be adapted to reversibly provide access to the internal volumes of the data processing devices.
For example, the different portions of the data processing devices (102) may be adapted to rotate, translate, or otherwise move with respect to the remaining portions of the data processing devices (102). When the different portions of the data processing devices (102) are in a first predetermination position and/or orientation, they may electromagnetically seal one or more internal volumes of the data processing devices (102). That is, they may limit the extent to which electromagnetic radiation within the internal volumes is able to propagate to an ambient environment. However, when the different portions of the data processing devices (102) are rotated, translated, and/or otherwise moved to a second predetermined position and/or orientation to enable access to the internal volumes, the data processing devices (102) may not be electromagnetically sealed. Consequently, electromagnetic radiation within the internal volumes may be less limited by the data processing devices (102) to propagate into the ambient environment when access to the internal volumes is provided.
The data processing devices (102) may include hinges, slides, knobs, and/or other mechanical devices that facilitate movement of the different portions of the data processing devices (102) to reversibly reconfigure the data processing devices (102) between states where access (i.e., physical accessibility) to the internal volumes of the data processing devices (102) is provided and states where access to the internal volumes of the data processing devices (102) is not provided.
While the system of
However, in the state illustrated in
In some embodiments of the invention, the first data processing device (104) automatically causes all, or a portion, of the electromagnetic interference emitting devices disposed within its internal volumes to suspend generation of electromagnetic interference when in the electromagnetic interference suppression compromised state illustrated in
Similar to
The top door (112) of, for example, the second data processing device (106) may be mounted to the frame (100) via rails that enable the second data processing device (106) to translate with respect to the frame (100) via application of physical force. Once translated to a predetermined location, the top door (112) may be opened by application of physical force by a user.
By opening the top door (112), physical access to the internal volumes of the second data processing device (106) may be provided. Consequently, the internal configuration of the internal volumes of the second data processing device (106) may be modified. For example, electromagnetic interference emitting devices may be removed from and/or added to the internal volumes of the second data processing device (106). Similarly, computing devices may be added to and/or removed from the internal volumes of the second data processing device (106).
However, in the state illustrated in
In some embodiments of the invention, the second data processing device (106) automatically causes all, or a portion, of the electromagnetic interference emitting devices disposed within its internal volumes to suspend generation of electromagnetic interference when in the electromagnetic interference suppression compromised state illustrated in
Thus, as illustrated in
As discussed above, a system in accordance with one or more embodiments of the invention may include one or more data processing devices.
To do so, the second data processing device (106) may include a chassis (198). The chassis (198) may be a structure that is mountable to a frame. By being mountable to a frame, the chassis (198) may be usable in a high density environment. For example, the chassis (198) may be a rail mount chassis. The chassis (198) may be mountable via other methods (e.g., using mechanical features other than rails such as bolts, screws, pins, etc.).
The chassis (198) may include a front vent (200), a rear vent (204), a support module (208), and a payload module (210). Each of these components of the second data processing device (106) is discussed below.
The front vent (200) may be a physical device for (i) enabling gas flow through the second data processing device (106) and (ii) limiting the propagation of electromagnetic interference from an internal volume of the second data processing device (106) and/or attenuating electromagnetic interference that propagates from an internal volume of the second data processing device (106) to an ambient environment around the second data processing device (106) via the front vent (200).
In one or more embodiments of the invention, the front vent (200) reflects and/or attenuates electromagnetic radiation that is propagating from the internal volume (214) to an ambient environment through the front vent (200) by at least 90 decibels (or another suitable level such as, for example, 30 decibels, 45 decibels, 60 decibels, 75 decibels, etc.). By doing so, the front vent (200) may delineate one of the walls of the internal volume (214) to enable the internal volume (214) to be electromagnetically suppressed and/or isolated by 90 decibels (or another suitable level of suppression/isolation) from the ambient environment and/or other portions of the chassis (e.g., the support module (208)).
In one or more embodiments of the invention, the front vent (200) is a rectangular structure formed with holes (202) that enable gasses to flow between the ambient environment surrounding the second data processing device (106) and an internal volume of the second data processing device (106). By doing so, the second data processing device (106) may provide thermal management services to components disposed within the second data processing device (106) by controlling the flow of gasses from the ambient environment through the second data processing device (106).
For example, the second data processing device (106) may be used in a high-density computing environment in which a source of cool gas is supplied to a first side of the second data processing device (106). In such an environment, the second data processing device (106) may cause the cool gas to flow into the second data processing device (106) via the front vent (200) and exhaust gas out a second side of the second data processing device (106) (e.g., out of the support module (208)). Alternatively, the second data processing device (106) may cause a reverse gas flow, with respect to the gas flow discussed above, if the source of cool gas is supplied proximate to the support module (208) rather than proximate to the front vent (200).
The structure of the front vent (200) may also be adapted to limit propagation of electromagnetic radiation through the front vent (200) and/or attenuate electromagnetic radiation that propagates through the front vent (200). For example, the size, position, number, shape, and/or other characteristics of the holes (202) through the front vent may be adapted to (i) limit propagation of electromagnetic radiation and/or (ii) attenuate propagating electromagnetic radiation. In another example, the thickness and material choice of the front vent (200) may be adapted to (i) limit propagation of electromagnetic radiation and/or (ii) attenuate propagating electromagnetic radiation. By being so adapted, the front vent (200) may attenuate electromagnetic radiation that propagates through the front vent (200) by at least 90 decibels or another desirable quantity (e.g., 30 decibels, 45 decibels, 60 decibels, 75 decibels, 120 decibels, etc.).
To facilitate the flow of gas between the ambient environment and the internal volume of the second data processing device (106), the size, position, number, shape, and/or other characteristics of the holes (202) may be selected to meet gas flow requirements for thermal management purposes while providing electromagnetic interference suppression characteristics.
In one or more embodiments of the invention, the rear vent (204) is similar to the front vent (200). For example, the rear vent (204) may provide similar attenuation and/or restriction of propagation of electromagnetic radiation while enabling gasses to flow between internal volumes of the second data processing device. The rear vent (204) may have a similar structure to that of the front vent (200). However, the structure (e.g., different hole pattern, thickness, hole type, etc.) and/or electromagnetic (e.g., attenuation and/or reflection of electromagnetic radiation) and/or hydrodynamic (e.g., impedance to fluid flow) characteristics of the rear vent (204) may be different from the front vent (200) without departing from the invention.
The front vent (200) and/or the rear vent (204) may be further adapted to facilitate obtaining of optical information from devices disposed within the payload module (210). The optical information may be used to determine an optical state of the respective devices disposed within the payload module (210) (and/or other locations within the second data processing device).
In one or more embodiments of the invention, the front vent (200) and/or the rear vent (204) is adapted to facilitate obtaining of optical information by including a feature that enables a portion of an optical state detector (discussed in greater detail with respect to
While the optical state detector has been described as extending through a vent, as will be discussed in greater detail below, the optical state detector may extend through different structures of data processing devices that delineate boundaries of internal volumes that suppress electromagnetic interference without departing from the invention.
The payload module (210) may be a physical device for (i) housing electromagnetic interference devices, (ii) limiting propagation of electromagnetic interference from internal volumes of the second data processing device (106) to the ambient environment surrounding the second data processing device (106), and (iii) thermally regulating devices disposed within the payload module (210). For additional details regarding the payload module (210), refer to
The support module (208) may be a physical device for housing devices that provide services to devices disposed within the payload module (210). For example, the support module (208) may house one or more power supplies (e.g., a power system), fans (e.g., a thermal management system), networking devices (e.g., a communication system), and/or computing devices. The aforementioned devices may provide corresponding services to devices disposed in other portions of the second data processing device (106) and/or devices located in other locations (i.e., external to the second data processing device (106).
In one or more embodiments of the invention, the support module (208) does not provide electromagnetic interference management services to devices disposed within the support module (208), in contrast to the payload module (210). For example, the support module (208) may not intentionally isolate electromagnetic interference generated by devices disposed within the support module (208) from the ambient environment surrounding the second data processing device (106). Intentionally isolating electromagnetic interference means that the structure of a physical structure is adapted to provide such isolation. While many types of physical structures may provide some degree of electromagnetic interference isolation as an inherent consequence of their existence, the electromagnetic interference isolation is not intended. Rather, the physical structures may exist for their other properties such as mechanical strength while providing some degree (albeit low) of electromagnetic interference isolation. Thus, while the support module (208) may to some degree electromagnetically separate devices disposed within the support module (208) from the ambient environment, the support module (208) does not provide electromagnetic interference management services. Providing electromagnetic interference management services may refer to providing at least 20 decibels of attenuation or another suitable level of attenuation (e.g., at least 35 decibels).
In one or more embodiments of the invention, providing electromagnetic interference management services reduces the strength of electromagnetic radiation by at least 20 decibels when the electromagnetic radiation propagates from an internal volume of a data processing device to an ambient environment outside of the data processing device.
The one or more power supplies may supply power to other devices. For example, the power supplies may provide power to electromagnetic interference emitting devices disposed within the payload module (210), other types of devices (e.g., computing device) disposed within the payload module, and/or devices located in other areas.
The one or more power fans may provide thermal management services to other devices. For example, the fans may regulate the flow of gasses through the second data processing device and, consequently, manage the thermal state of electromagnetic interference emitting devices and/or other types of devices disposed in the payload module (210) and/or the support module (208).
The one or more power networking devices may provide communication services to other devices (e.g., providing network services). For example, the networking devices may manage network interfaces that enables the second data processing device (106) to communicate with other devices (e.g., computing devices that may be controlling the operation of the electromagnetic interference emitting devices).
The one or more computing devices may manage the operations of the other entities of the second data processing device (106). For example, the computing devices may send messages to the electromagnetic interference emitting devices to perform predetermined functionality. Such messages, when received by the electromagnetic interference emitting devices may cause the electromagnetic interference emitting devices to stop and/or start emitting electromagnetic interference (and/or perform other actions).
The computing devices may send such instructions when (or around the time when) the electromagnetic interference suppression state of the second data processing device (106) is changed (i.e., when portions of the second data processing device (106) are physically reconfigured). The computing devices may make such determinations based on any number of sensors (not shown) that monitor the physical configuration of the second data processing device (106). The sensors may be disposed, for example, in the payload module, on the vents, or at other locations such that measurements by the sensors indicate the thermal state of components of the second data processing device for which thermal management services (e.g., monitoring the thermal state of components and taking actions such as modifying the rate of gas flow to manage the thermal state of the components) are being provided.
In another example, the computing devices may send messages to fan controllers (not shown) or other devices that manage the operation of gas flow control devices disposed within the second data processing device (106). The computing devices may send such messages based on the thermal state (i.e., temperature) of one or more devices disposed within the second data processing device (106). The computing devices may monitor such thermal states using any number of sensors (not shown) and/or based on messages received from the one or more devices disposed within the second data processing device (106).
In response to receipt of such messages, the fan controllers or other devices may modify the operational state of the gas flow control devices. By doing so, the computing devices may change the thermal state of devices disposed within the second data processing device (106) by controlling the flow of gasses through the second data processing device (106).
To manage the operation of the other entities of the second data processing device (106), one or more processors of the computing devices may execute instructions (e.g., computer code), stored on a persistent storage, that cause the computing devices to perform all, or a portion, of the method illustrated in
To further clarify aspects of embodiments of the invention, a cross section diagram of the second data processing device (106) in accordance with one or more embodiments of the invention is shown in
As seen from
The internal volume (214) may be bounded, on four sides, by portions of the payload module (210). For example, the internal volume (214) may be bounded by a top door (212), a bottom (218), a first side (216), and a second side (not shown). These four components of the payload module (210) may define a rectangular shape of the internal volume (214) (e.g., may define four boundaries of the internal volume).
The internal volume (214) may be further bounded, on a fifth and sixth size, by the front vent (200) and the rear vent (204). The front vent (200) and the rear vent (204) may be on opposite sides of the internal volume (214). By doing so, the front vent (200) and the rear vent (204) may define a gas flow path through the payload module (210). For example, gasses may be able to flow from between the two vents through the internal volume (214).
As discussed above, the second data processing device may control gas flows disposed within the second data processing device to provide thermal management services. To do so, the second data processing device may include a thermal management system (220). The thermal management system (220) may include (i) flow control devices, (ii) temperature sensors, and/or (iii) a controller.
The controller may operate the flow control devices based on temperature information obtained from the temperature sensors and/or temperature information obtained from other devices (e.g., from electromagnetic interference emitting devices). For example, the controller may increase the flow rate of a gas flow disposed within the second data processing devices to manage the temperature of one or more devices within a predetermined range.
The flow control devices may be, for example, fans or other types of active devices for controlling the flow of gasses. The thermal management system (220) may include any number of flow control devices without departing from the invention.
The second data processing device may also include a power system (222). The power system may provide power to any number and/or types of devices disposed within the second data processing device. For example, the power system (222) may provide power to electromagnetic interference emitting devices disposed within the payload module (210), the thermal management system (220), a communication system (224), and/or computing devices (226).
To do so, the power system (222) may include, for example, one or more power supplies, regulators, controllers, and/or other types of components for providing power. The aforementioned components may identify components to which power is to be supplied, identify a quantity of power to supply to each of the components, and/or provide the power to each of the respective components. As will be discussed in greater detail below, the power system (222) may provide power using an interconnect (230).
The second data processing device may further include a communication system (224). The communication system (224) may provide communication services. As discussed above, due to the electromagnetic interference isolation provided by the second data processing device, components disposed within the internal volume (214) may be unable to communicate with other devices via wireless communications due to the electromagnetic isolation provided by the internal volume (214). To facilitate communications between the devices disposed in the internal volume (214) and other devices, the communication system (224) may provide communication services to the devices using wired connections.
To provide communication services, the communication system (224) may include, for example, one or more transceivers, communication processors, and/or other types of components for providing communication services. The aforementioned components may provide the communication services. The communication services may include, for example, exchanging network data units with electromagnetic interference emitting devices (and/or other types of devices) disposed in the payload module, a computing device (226) disposed in the support module (208), and/or other devices disposed outside of the second data processing device. By doing so, the aforementioned devices may communicate with one another via information included in the exchanged network data units. A network data unit may be a communication supported by a communication protocol that enables information to be transmitted. A network data unit may be, for example, a packet in the event that an internet protocol is utilized. Other types of communications protocols may be utilized without departing from the invention. As will be discussed in greater detail below, the communication system (224) may provide the communication services using an interconnect (230) (e.g., a wired path for communications purposes and/or other electrical purposes).
The computing device (226) may manage the operation of the components of the second data processing device. For example, the computing device (226) may manage the thermal management system (220), the power system (222), the communication system (224), and/or other components (such as electromagnetic interference emitting devices) disposed within the second data processing device. To manage the other devices, the computing device (226) may use the communication services provided by the communication system (224) as well as the interconnect (230).
The interconnect (230) may be a physical device for providing operable connections between devices disposed within the second data processing device. The interconnect (230) may support distribution of power by the power system (222) to any number of devices disposed within the payload module (210), the support module (208), and/or other locations.
For example, the interconnect (230) may include a set of wires that physically interconnect devices disposed within the second data processing device.
In one or more embodiments of the invention, the interconnect (230) facilitates distribution of power to electromagnetic interference emitting devices disposed within the payload module (210) while the electromagnetic interference emitting devices are isolated. By doing so, the electromagnetic interference emitting devices may be provided power without negatively impacting the operation of other devices due to electromagnetic interference generated by the electromagnetic interference emitting devices.
To do so, the second data processing device may include a back-plane (232). The back-plane may electromagnetically isolate the interconnect (230) from the internal volume of the payload module (210). For example, the back-plane (232) may be a metal sheet of sufficient thickness to prevent electromagnetic interference from penetrating through the back-plane (232).
The back-plane (232) may include any number of feedthroughs (234). The feedthroughs (234) may be physical devices that enable the interconnect (230) to physically connect to any number of devices disposed within the payload module (210).
While devices disposed in the internal volume may be controlled remotely (e.g., controlled by the computing device (226) or other types of devices), such control may be made by sending and receiving data to and from the devices. However, other types of information (other than that provided by the devices) may be collected from the devices disposed in the internal volume (214). For example, optical state information (as discussed above) may be obtain from the devices. Such information may be used to determine an operational state (or other information) regarding the devices that may not be present in the information provided by the devices using the interconnect.
For example, consider a scenario where a device disposed in the internal volume receives a request to perform an action. Performing the action may (i) change an operational state of the device and (ii) change an optical state of the device. After performing the action, a request for the operation state of the device may be obtained. However, due to an error state of the device, the device may indicate (in response to the request) that the device is in a second operation state that does not accurately reflect the actual operational state of the device. To improve the accuracy of determining the state of devices disposed in the internal volume (214), embodiments of the invention may provide a method for collecting optical information from devices disposed in the internal volume (214). The optical information may be used to determine an optical state of the respective devices. The optical state of the respective devices may be used to more accurately determine an actual operational state of the respective devices (and/or determine other information regarding the respective devices).
To further clarify the operation of the second data processing device,
To provide electromagnetic interference suppression services, the second data processing device may limit propagation of electromagnetic radiation emitted by the electromagnetic interference emitting devices (250) to within the payload module (210). By doing so, electromagnetic interference emitting devices (250) may perform the functionality while in high density computing environment without negatively impacting their operation of other devices disposed in the high density computing environment due to the emitted electromagnetic radiation.
To provide the communication services, power services, and/or management services, electromagnetic interference emitting devices (250) may be operably connected to the power system (222), the communication system (224), and/or the computing device (226), via the interconnect (230). By doing so, the operation of the electromagnetic interference emitting devices (250) may be managed by the computing device (226) and/or other devices operably connected to the electromagnetic interference emitting devices (250) via the communication system (224).
As discussed above, when the electromagnetic interference emitting devices (250) are operating, the optical states of the electromagnetic interference emitting devices (250) may change over time. For example, any of the electromagnetic interference emitting devices (250) may include a display that generates optical patterns corresponding to the operation of the respective device. As the operation of the respective devices changes, the optical patterns generated by the displays may change to reflect to changed operation of the respective devices.
To obtain information regarding the optical state of the devices disposed in a data processing, a system in accordance with one or more embodiments of the invention may include one or more optical state detectors.
In one or more embodiments of the invention, optical state detector (260) is a physical device adapted to obtain optical states of one or more devices disposed in the data processing device. To do so, the optical state detector (260) may include a controller (262) an optical collector (263). Each component of the optical state detector (260) is discussed below.
In one or more embodiments of the invention, the controller (262) is a physical device adapted to determine an optical state of the device based on an optical pattern obtained using an optical collector (263). For example, the controller (262) may obtain an optical pattern using the optical collector. The optical pattern may be based on optical electromagnetic radiation (e.g., light) corresponding to a device.
In one or more embodiments of the invention, the optical state of the device is a representation of a pattern of light emitted by the device. The pattern of light emitted by the device may be emitted by a display of the device. The optical state of the device may be, for example, an image of a display of the device. The optical state of the device may be an image of a different portion of the device without departing from the invention. For example, in some embodiments of the invention that optical state may be an image of any portion of the device that may emit light (or otherwise change its optical appearance) to convey information.
In one or more embodiments of the invention, the controller (262) includes an image sensor (262.4) to convert the optical pattern obtained using the optical collector (263) to an optical state of the device. For example, the image sensor (262.4) may be a charge coupled device. The image sensor (262.4) may be operatively connected to the optical collector (263) to enable the image sensor (262.4) to obtain the optical pattern using optical collector (263).
In one or more embodiments of the invention, the controller (262) includes a computing device (262.2) that orchestrates the operation of optical state detector (260). The computing device (262.2) may obtain one or more optical states of devices and provide the optical state of the devices to other entities. The other entities may control the operation of the devices. The other entities may utilize such optical state information provided by the controller (262) to control the operation of the devices. For example, the other entities may make determinations regarding the operational states of the devices using the optical state information and take action (e.g., send requests to the devices to perform predetermined functionality) based on the determined operational states of the devices.
The computing device (262.2) may be, for example, a mobile phone, tablet computer, laptop computer, desktop computer, server, embedded computer, or cloud resource. The computing device (262.2) may include one or more processors, memory random access memory), and persistent storage (e.g., disk drives, solid state drives, etc.). The persistent storage may store computer instructions (in addition to other data), e.g., computer code, that (when executed by the processor(s) of the computing device) cause the computing device (262.2) to perform the functions of the controller (262) described in this application and/or all, or a portion, of the method illustrated in
In one or more embodiments of the invention, the functionality of the computing device (262.2) is performed by another device separate from the controller (262). For example, the functionality of the computing device (262.2) may be performed by a computing device (e.g., 226,
The optical collector (263) may be a physical device for obtaining optical patterns corresponding to devices. The optical collector (263) may be adapted to be disposed through a boundary of an internal volume of a data processing device that suppresses electromagnetic interference without enabling electromagnetic interference to propagate out of the internal volume without being attenuated by a predetermined amount (e.g., 90 decibels, 35 decibels, etc.). The optical collector (263) may further be adapted to obtain optical patterns from devices and provide the optical patterns to the controller (262).
In one or more embodiments of the invention, the optical collector (263) does not include any conductive material. In one or more embodiments of the invention, the optical collector (263) does not include any semi-conductive material. In one or more embodiments of the invention, the optical collector (263) comprises electrically insulating materials.
To provide the above noted functionality of the optical collector (263), the optical collector may include an extension (264), a director (266), and an optical pickup (268). Each of these components of the optical collector (263) is discussed below.
In one or more embodiments of the invention, the extension (264) is a physical structure adapted to (i) traverse a boundary of an internal volume without facilitating propagation of electromagnetic radiation through the boundary and (ii) provide optical patterns obtained from the optical pickup (268) to the controller (262). The extension (264) may include one or more optical fibers. The one or more optical fibers may be operably coupled to the optical pickup (268) on a first end and may be operably coupled to the controller (262) on the other end. The one or more optical fibers may enable optical patterns to be transmitted along the length of the extension (264).
The extension (264) may further including sheathing (not shown) and/or structural members (not shown) for maintaining a shape of the extension (264). For example, the extension (264) may have a rod-like shape that enables the optical pickup (268) to be disposed away from the controller (262) while being physically supported by the extension.
The director (266) may be a portion of the extension (264) that facilitates orienting and/or positioning of the optical pickup (268) with respect to an axis (265) of the extension (264). For example, the director (266) may be a portion of the extension (264) that may be rotated away from an axis (265) of the extension (264). Consequently, the optical pickup (268) may be positioned and/or oriented away from the axis (265) of the extension (264).
The optical pickup (268) may be a physical device for obtaining an optical pattern. For example, the optical pickup (268) may include one or more lenses that enable light emitted by the device to be captured and/or focused onto the extension (264) in a manner that enables the optical pattern to be transmitted along the length of the extension (264).
While the optical state detector (260) has been described and illustrated in
As discussed above, the optical state detector (260) may be used in conjunction with and/or may be a part of a data processing device. To further clarify potential uses of the optical state detector (260),
As seen from
The optical pickup (268) may be disposed proximate to one of the devices disposed inside of the internal volume. By doing so, the optical pickup (268) may obtain optical radiation (270) from the device to obtain an optical pattern by focusing optical radiation (270). The obtained optical pattern may be transmitted to the controller (262) through the extension (264). For example, as described above, the extension (264) may include one or more optical fibers. The optical fibers may be, for example, optical tubes that facilitate transmission of optical radiation along the length of the optical fibers. Thus, the optical pattern obtained by the optical pickup (268) may be provided to a first end of an optical fiber, transmitted along the length of optical fiber, and provided to the controller (262) that is coupled to a second end of the optical fiber.
Once controller (262) obtains the optical pattern, an optical state of the device may be determined based on the optical pattern. For example, the controller (262) may focus the optical pattern on an image sensor to obtain a digital representation of the optical state of the device. In other words, an image of a portion (e.g., a screen/display/light/other optical indicator) of the device.
The controller (262) may provide the optical state of the device to any number of other devices. While not illustrated in
In one or more embodiments of the invention, the controller (262) is adapted to determine the optical states of devices in response to requests for the optical states from other devices. For example, the controller (262) may receive a request for an optical state of device from a computing device that is controlling the operation of the device. In response to receiving the request, the controller (262) may obtain optical state of the device, as discussed above, and provide the optical state of the device to the computing device via an operable connection to the computing device.
While the optical state detector (260) is illustrated in
For example, the controller (262) of the optical state detector may be operably connected to a first optical collector (276) and a second optical collector (278). The aforementioned optical collectors may facilitate obtaining of first optical radiation (272) for a first device and second optical radiation (274) from a device. By doing so, the optical state detector may be able to simultaneously obtain optical state information for multiple devices.
The multiple-optical pickup optical collector (280) may be an optical collector that includes multiple optical pickups. Each of the multiple optical pickups may obtain optical radiation from corresponding devices. For example, a first optical pickup may obtain the first optical radiation (272) and a second optical pickup the obtain the second optical radiation (274). Each of the optical pickups may provide optical patterns to corresponding optical fibers disposed in the extension (264). By doing so, the optical state detector may be able to simultaneously obtain optical state information for multiple devices.
To provide the above-noted functionality of an optical state detector, a data processing device in accordance with one or more embodiments of the invention may perform all or a portion of the method illustrated in
While
In step 300, performance of a function of the device is initiated.
In one or more embodiments of the invention, the function of the device is initiated by sending a message to the device requesting performance of the function. The message may specify, for example, the function to be performed, a duration for performing the function, parameters for performing the function, and/or other types of information that facilitate performance of the function by the device. In response to receiving the message, the device may perform the requested function.
In one or more embodiments of the invention, the device is an electromagnetic interference emitting device. For example, the device may be a cell phone disposed in an internal volume of the data processing device that is adapted to suppress electromagnetic interference emitted by the cell phone.
In step 302, electromagnetic radiation from the device is obtained after initiating the performance. In one or more embodiments of the invention, electromagnetic radiation is obtained using an optical state detector. For example, the electromagnetic radiation may be obtained by obtaining an optical pattern from the device. The optical pattern may be obtained using an optical pickup
In one or more embodiments of the invention, the optical pattern is light emitted from the display of the device. Optical pattern may be light emitted from other portions of the device without departing from the invention
In one or more embodiments of the invention, the optical pattern is transmitted through a boundary of an internal volume of the data processing device that suppresses electromagnetic interference to obtain electromagnetic radiation. For example, a portion of the optical state detector may be disposed through the boundary of the internal volume. The portion may be, for example, an optical fiber.
In one or more embodiments of the invention, the optical state detector is used by sending one or more messages to the optical state detector. The message may request that the optical state detector perform one or more of its functions. For example, the computing device may send a message to the optical state detector requesting of the optical state detector obtain an optical state of the device. To do so, optical state detector may obtain the electromagnetic radiation.
In one or more embodiments of the invention, electromagnetic radiation is light from the device. All or a portion of the light may be generated by the device. All or a portion of the light may be light reflected off of the device.
In step 304, it is determined whether electromagnetic radiation indicates that the device performed the function.
In one or more embodiments of the invention, the determination is based on an optical state of the device. The optical state of the device may be based on the electromagnetic radiation obtained in step 302. For example, the electromagnetic radiation may be transmitted to a collector of the optical state detector. Once transmitted to the optical state detector, an image sensor may generate an image based on the electromagnetic radiation (e.g., light) as the optical state of the device.
In one or more embodiments of the invention, the optical state of the device is used to determine an operational state of the device to determine whether the device performs the function. For example, performance of the function may be associated with the predetermined optical state of the device. If the optical state obtained from the device does not match the predetermined optical state, it may be determined that the device did not perform the function. If the optical state obtained from the device does match the predetermined state, it may be determined that device did perform the function.
If it is determined that the device performed the function, the method may proceed to step 306. If it is determined that the device did not perform the function, the method may proceed to step 308.
In step 306, a first action set is performed based on the performance of the function. In other words, the computing device orchestrating operation of the device may perform first action set when it is determined that the device performed the function.
In one or more embodiments of the invention, the first action set is at least one action to be performed when the device performs the function. For example, the at least one action may be to perform a different function. The at least one action may be other types of actions without departing from the invention.
The method may end following step 306.
Returning to step 304, the method may proceed to step 308 if the device did not perform the function.
In step 308, a section action set is performed based on the nonperformance of the function. In other words, the computing device orchestrating operation of the device may perform a second action set when it is determined that the device did not perform the function.
In one or more embodiments of the invention, the second action set is at least one action to be performed when the device does not perform the function. For example, the at least one action may be to repeat performance of the function. The at least one action may be other types of actions without departing from the invention.
The method may end following step 308.
Thus, via the method illustrated in
To further clarify embodiments of the invention, a non-limiting example is provided in
Consider a scenario as illustrated in
However, due to an unexpected occurrence with respect to the operation of the device (402), the color of the light emitted by the pixels of the display does not correspond to the first picture (420). Thus, the optical state of the device (402) differs from the predetermined optical state of the device (402) when the display of the device (402) emits light of any color and intensity corresponding to the first picture (420).
While the device (402) displays the first picture, the optical state detector (400) obtains light from the display (424). To do so, the optical state detector (400) obtains light emitted by the display while the first picture is being displayed. The light is transmitted to a controller of the optical state detector (400) through boundary of an internal volume that electromagnetically isolates the device (402) from the optical state detector (400), the computing device (404), and/or other devices (not shown).
Using the obtained light from the display, the optical state detector (400) generates an image based on the light. For example, the light may be directed onto an image sensor such as a charge coupled device. In response to receiving the light, the image sensor may generate a digital representation of the light. By doing so, the generated image based on the light may represent an optical state of the device (402). For example, the image may reflect the light emitted from the display of the device (402).
After generating the image, the optical state detector (400) provides the image based on the light (426) to the computing device (404). By doing so, the computing device (404) may be informed of optical state of the device (402).
Using the image, the computing device (404) identifies a difference between the first picture in the image (428). As noted above, due to the unexpected occurrence, the optical state of the device (402) displaying the first picture (422) did not correspond to the predetermined optical state associated with the first picture (420).
Because the computing device (404) identify the difference between the first picture in the image (428), the computing device (404) determines that a second action set associated with improper operation of the device (402) should be performed. The second action set includes display of a second picture (430) by the device (402). To cause the device (402) to display the second picture (430), the computing device (404) sends a request to the device (402) to display the second picture (430).
Thus, as illustrated by the example described with respect to
As discussed above, embodiments of the invention may be implemented using computing devices.
In one embodiment of the invention, the computer processor(s) (502) may be an integrated circuit for processing instructions. For example, the computer processor(s) may be one or more cores or micro-cores of a processor. The computing device (500) may also include one or more input devices (510), such as a touchscreen, keyboard, mouse, microphone, touchpad, electronic pen, or any other type of input device. Further, the communication interface (512) may include an integrated circuit for connecting the computing device (500) to a network (not shown) (e.g., a local area network (LAN), a wide area network (WAN) such as the Internet, mobile network, or any other type of network) and/or to another device, such as another computing device.
In one embodiment of the invention, the computing device (500) may include one or more output devices (508), such as a screen (e.g., a liquid crystal display (LCD), a plasma display, touchscreen, cathode ray tube (CRT) monitor, projector, or other display device), a printer, external storage, or any other output device. One or more of the output devices may be the same or different from the input device(s). The input and output device(s) may be locally or remotely connected to the computer processor(s) (502), non-persistent storage (504), and persistent storage (506). Many different types of computing devices exist, and the aforementioned input and output device(s) may take other forms.
Embodiments of the invention may provide a method, system, and device for managing electromagnetic interference. A system in accordance with embodiments of the invention may manage electromagnetic interference at a data processing device level. That is, such devices may include functionality to limit the propagation of electromagnetic interference from within data processing devices to an ambient environment surrounding the data processing device. By doing so, such data processing devices may be used in a high-density environment without negatively impacting the functionality of the high-density environment.
A data processing device in accordance with embodiments of the invention may enable the optical states of devices disposed within the data processing device to be determined while suppressing electromagnetic interference generated by the devices. To do so, the data processing device may include an optical state detector that obtains optical states of the devices. To obtain the optical states the devices, optical state detector may obtain optical radiation from the devices, transmit the optical radiation through boundary of an internal volume in which the devices are disposed, and generate the optical states of the devices based on the optical radiation. Such information may be used to more effectively control the operation of the devices by determining an operational state of the devices with a higher degree of accuracy in determining the operational state of the devices without having access to optical state information associated with the devices.
