A further aspect provides a product, comprising: a storage device that stores code, the code being executable by a processor and comprising: code that receives an indication to transmit an electrical pulse to an electropermanent magnet; code that transmits, responsive to the code that receives, the electrical pulse to the electropermanent magnet; and code that affects a magnetic field associated with the electropermanent magnet responsive to receiving the electrical pulse.
The foregoing is a summary and thus may contain simplifications, generalizations, and omissions of detail; consequently, those skilled in the art will appreciate that the summary is illustrative only and is not intended to be in any way limiting.
For a better understanding of the embodiments, together with other and further features and advantages thereof, reference is made to the following description, taken in conjunction with the accompanying drawings. The scope of the invention will be pointed out in the appended claims.
It will be readily understood that the components of the embodiments, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations in addition to the described example embodiments. Thus, the following more detailed description of the example embodiments, as represented in the figures, is not intended to limit the scope of the embodiments, as claimed, but is merely representative of example embodiments.
Reference throughout this specification to “one embodiment” or “an embodiment” (or the like) means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearance of the phrases “in one embodiment” or “in an embodiment” or the like in various places throughout this specification are not necessarily all referring to the same embodiment.
Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments. One skilled in the relevant art will recognize, however, that the various embodiments can be practiced without one or more of the specific details, or with other methods, components, materials, et cetera. In other instances, well known structures, materials, or operations are not shown or described in detail to avoid obfuscation.
Manipulation of the sections of a convertible device allows users to utilize the device in the fashion that suits their contextual needs. For example, a user having a convertible laptop may substantially interact with their device in laptop mode throughout the workday. Once the user is finished working, they may convert their device to a tablet (e.g., by disconnecting the keyboard base section from the display section, etc.), which may provide them with greater interaction flexibility.
Conventional techniques for facilitating attachment and/or detachment of sections of a convertible device are largely mechanical in nature. Generally, attachment of one section to another (e.g., a tablet to a base, etc.) require a protruding portion of one section (e.g., a hook, etc.) to interact with a receptacle portion of the other section. Additionally, conventional designs also provide a way to lock/unlock these sections together when they are connected (e.g., via a spring, slider, muscle wire, switch, etc.). All of these additional components add complexity to the device operation and also produce an unattractive device appearance.
Accordingly, an embodiment provides a device with one or more magnetic components that enable a user to attach and/or detach certain sections of the device seamlessly. In an embodiment, an indication may be received by the device to transmit an electrical pulse to an electropermanent magnet housed in a section of the device. The indication may be derived from sensor data, active application data, switch data, a combination thereof, and the like. Responsive to receiving the indication, an embodiment may then transmit an electrical pulse to the electropermanent magnet, which may thereby affect an active state of a magnetic field associated with the electropermanent magnet. When the magnetic field is active and a magnetic portion of another section of the device is brought into proximity with a portion of the section housing the electropermanent magnet, the attractive forced produced by the active magnetic field may secure these two sections together. When the magnetic force is deactivated, the force is removed and the two sections may be separated. Such a method may provide for easy and attractive securement of device sections.
The illustrated example embodiments will be best understood by reference to the figures. The following description is intended only by way of example, and simply illustrates certain example embodiments.
While various other circuits, circuitry or components may be utilized in information handling devices, with regard to smart phone and/or tablet circuitry 100, an example illustrated in
There are power management chip(s) 130, e.g., a battery management unit, BMU, which manage power as supplied, for example, via a rechargeable battery 140, which may be recharged by a connection to a power source (not shown). In at least one design, a single chip, such as 110, is used to supply BIOS like functionality and DRAM memory.
System 100 typically includes one or more of a WWAN transceiver 150 and a WLAN transceiver 160 for connecting to various networks, such as telecommunications networks and wireless Internet devices, e.g., access points. Additionally, devices 120 are commonly included, e.g., an image sensor such as a camera, audio capture device such as a microphone, etc. System 100 often includes one or more touch screens 170 for data input and display/rendering. System 100 also typically includes various memory devices, for example flash memory 180 and SDRAM 190.

Information handling circuitry, as for example outlined in
Referring now to
In an embodiment, the electropermanent magnet may be configured to have a coil wound around it. When an electrical pulse is transmitted to the electropermanent magnet (e.g., via a pulse transmitter integrated into the device housing, etc.), the magnetic field surrounding the electropermanent magnet may be affected. More particularly, if inactive the magnetic field may be activated and if active the magnetic field may be deactivated. When the magnetic field is active, other metallic objects may be attracted to it and vice versa. The magnetic field may remain in a particular attractive state until another electrical pulse is received.
In an embodiment, the indication to transmit the electrical pulse to the electropermanent magnet may be derived from one or more data sources. For instance, sensor data may be used to dynamically identify when to turn the magnetic field on or off. Non-limiting examples of sensors that may produce relevant data include proximity sensors, camera sensors, audio sensors, a combination thereof, and the like.
In an embodiment, one or more proximity sensors may be utilized to detect when the two sections of the device are brought into proximity with one another. Responsive to determining that the sections are within a predetermined threshold distance of each other, an embodiment may provide an indication to transmit the electrical signal to the electropermanent magnet. Additionally or alternatively, an embodiment may utilize proximity sensors to determine when a user's hand is within a predetermined distance of a portion of a connected section (e.g., an embodiment may identify that a user's hand has approached a commonly grasped position on the connected section that is held when disconnecting the connected section from the base section, etc.). Such detection may provide an indication that the user desires to remove the connected section from the base section.
In an embodiment, one or more camera sensors (e.g., front-facing cameras, worldview cameras, etc.) integrated into one or more sections of the device may be utilized to determine when to transmit an electrical pulse. More particularly, one or more of the cameras may be always-on and may continually capture images and/or videos of user movement, device movement, etc., which may be analyzed in substantially real-time to determine whether a trigger indication is present. For example, an embodiment may identify that one section of the device is moving toward another section. Such a detection may provide an indication that a user wishes to connect the two sections together. Additionally or alternatively, an embodiment may track user movements to determine whether a user has performed a movement that may be indicative of their intention to separate the device sections (e.g., an embodiment may determine that a user is moving their hand toward a commonly grasped position on the connected section that is held when disconnecting the two sections from one another, etc.).
In an embodiment, one or more audio sensors (e.g., always-on microphones, etc.) may be utilized to detect situations in which a user has provided some audible indication that they desire to separate or attach the sections. For example, the audible indication may be an explicit audible command to separate the sections. As another example, the audible indication may be more contextual in nature. More particularly, an embodiment may record and subsequently analyze a user's speech to determine whether they have indicated an intent to attach or separate the sections. For example, a user may provide an indication in a conversation they are having with another individual of their intent to separate the sections (e.g., “I'm going to watch that movie on my tablet”, etc.).
Another data source that may be utilized to determine whether an indication was received is active application data. As used herein, active application data may refer to a top level application a user is interacting with. An embodiment may receive an indication of this application and may thereafter determine, from this knowledge, whether to transmit an electrical pulse to the electropermanent magnet. For example, responsive to determining that a word processing application is being interacted with, an embodiment may receive an indication to transmit an electrical pulse to the electropermanent magnet to activate the magnetic field. Such an indication may be transmitted based upon a device's knowledge that the user, or a crowdsourced group of users, prefers to interact with word processing applications in laptop mode. Alternatively, as another example, responsive to determining that a video streaming application is active, an embodiment may receive an indication to transmit an electrical pulse to the electropermanent magnet to deactivate the magnetic field. Such an indication may be transmitted based upon a device's knowledge that the user, or a crowdsourced group of users, prefers to watch videos on their device in tablet mode.
Yet another data source that may be utilized to determine whether an indication was received is switch data. More particularly, a switch may exist on the device (e.g., a physical switch, a virtual switch displayed on a display screen of the device, etc.) that a user may toggle when they want to adjust the magnetic field. Responsive to detecting that a user has flipped the physical or virtual switch, an embodiment may transmit an electrical pulse to the electropermanent magnet.
An embodiment may require that a supporting force be detected on the connecting section prior to disabling the magnetic field. More particularly, if the attractive force between the two sections is disabled and the connecting section has no support, then that section may simply fall down, potentially causing harm to the connecting section. Accordingly, an embodiment may utilize one or more of the aforementioned types of sensor data or use additional data (e.g., pressure sensor data, etc.) in making this determination. An example of a supporting force that may be detected and that may subsequently authorize deactivation of the magnetic field is a user's grasping of the connecting section with their hand. Additionally to the foregoing, an embodiment may require that the supportive force be detected for a predetermined period of time (e.g., 3 seconds, 5 seconds, 10 seconds, etc.) prior to deactivating the magnetic field.
Responsive to not receiving, at 301, an indication to transmit an electrical pulse, an embodiment may, at 302, take no additional action. Conversely, if an indication is received, at 301, to transmit an electrical pulse, an embodiment may, at 303, transmit the electrical pulse to the electropermanent magnet via a pulse transmitter. Receipt of the pulse at the electropermanent magnet may adjust the polarity of the electropermanent magnet, which may correspondingly affect, at 304, an attractive state of the magnetic field, as previously described above. If the magnetic field was originally off, receipt of the pulse may therefore activate the magnetic field and vice versa. Through the activation and deactivation of the magnetic field, an embodiment may secure two sections together or detach them from one another.
It is important to note that although the foregoing disclosure was described primarily in relation to convertible devices, specifically laptops, handhelds, etc., such a designation is not limiting. More particularly, the magnetic attachment/detachment mechanism described above may be utilized in virtually any device/object containing two or more sections that need to be secured together. For example, the concepts described above may be implemented into kitchen appliances, cabinetry, furniture, other devices and/or objects, etc.
The various embodiments described herein thus represent a technical improvement to conventional methods for attaching and/or detaching two or more sections of a device. Using the techniques described herein, an embodiment may receive an indication to transmit an electrical pulse to an electropermanent magnet. The indication may be derived from one or more different data sources such as sensor data, active application data, switch toggle data, etc.) Responsive to receiving the indication, an embodiment may transmit the electrical pulse to the electropermanent magnet, which may thereby affect an attractive state of the magnetic field surrounding the electropermanent magnet. For example, the electrical pulse may cause the magnetic field to activate or deactivate, which may influence the ability of the electropermanent magnet to secure other metallic objects (e.g., such as a connecting section of a device, etc.). Such an embodiment may optimize the way in which users manipulate their convertible devices from one mode to another.
