Advantageously, ultrasound module 201 may be configured to be removable from portable ultrasound system 100 as discussed later and in more detail with reference to
Ultrasound module 201 may include input interfaces for ultrasound equipment. In some embodiments, ultrasound module 201 includes one or more pin type ultrasound probe interfaces 203. Pin type ultrasound interface 203 may allow an ultrasound probe to connect to an ultrasound board 191 included in ultrasound module 201. For example, an ultrasound probe connected to pin type ultrasound interface 203 may be connected to ultrasound board 191 via transducer/probe pin interface 181. In some embodiments, pin type ultrasound interface 203 allows communication between components of portable ultrasound system 100 (e.g., ultrasound module 201, power supply module 301, main circuit board module 401, or other components included in or connected with portable ultrasound system 100) and an ultrasound probe. For example, control signals may be provided to an ultrasound probe (e.g., controlling the ultrasound emissions of the probe) and data may be received by ultrasound module 201 from the probe (e.g., imaging data).
In some embodiments, ultrasound module 201 may include locking lever system 500 for securing an ultrasound probe. For example, an ultrasound probe may be secured in pin type ultrasound probe interface 203 by locking lever system 500.
In further embodiments, ultrasound module 201 includes one or more socket type ultrasound probe interfaces 205. Socket type ultrasound probe interfaces 205 may allow a socket type ultrasound probe to connect to an ultrasound board 191 included in ultrasound module 201. For example, an ultrasound probe connected to socket type ultrasound probe interface 205 may be connected to ultrasound board 191 via transducer/probe socket interface 185. In some embodiments, socket type ultrasound probe interface 205 allows communication between components of portable ultrasound system 100 (e.g., ultrasound module 201, power supply module 301, main circuit board module 401, or other components included in or connected with portable ultrasound system 100). For example, control signals may be provided to an ultrasound probe (e.g., controlling the ultrasound emissions of the probe) and data may be received by ultrasound module 201 from the probe (e.g., imaging data).
In further embodiments, ultrasound module 201 includes computation, control, or other support hardware. The support hardware may facilitate the ultrasound functions performed by ultrasound module 201. For example, ultrasound module 201 may include processors, memory, integrated circuits, graphics processing units (GPU), central processing units (CPU), controllers, application specific integrated circuits (ASICs), or other computational hardware. Ultrasound module 201 may perform tasks such as controlling ultrasound probe output (e.g., controlling active transducer elements, beam steering, controlling ultrasound pulses, etc.), receiving ultrasound probe input, performing post-processing, generating images from input provided by an ultrasound probe, storing input data, storing images, or otherwise manipulating data and/or hardware related to ultrasound imaging.
In some embodiments, main circuit board 161 and/or power supply board 179 are configured to support ultrasound modules 201 using typically 128 channels or 64 channels for imaging but not limited to either 128 or 64 channel configurations. Advantageously, this allows for a user of the system to perform imaging tasks with a less expensive channel count ultrasound module 201 but switch to a higher channel count ultrasound module 201 when desired (e.g., to achieve greater resolution) easily and quickly due to the modular nature of portable ultrasound system 100. In some embodiments, the connections between ultrasound module 201 and other components is configured to facilitate this operation. For example, connectors may designed to accept multiple configurations of connectors on ultrasound module 201 (e.g., a 64 channel ultrasound module 201 may have fewer pins or other connection features than a 128 channel ultrasound module 201). In other embodiments, the components of portable ultrasound system 100 and/or ultrasound module 201 may determine the number of channels used by a connected ultrasound module 201 and adjust parameters accordingly. For example, power provided to ultrasound module 201 may be increased or decreased, cooling fan speed may be increased or decreased, more or less memory may be allocated to systems of ultrasound module 201, a user interface may be adjusted to display more, less, or different information, and/or other parameters of components or functions of portable ultrasound system 100 may be adjusted.
Ultrasound module 201 can connect to one or more of the other components of portable ultrasound system 100 (e.g., power supply module 301 and main circuit board module 401) by connectors configured to support the modularity of the ultrasound module 201. For example, the connectors may be configured to ensure accurate and complete connection between ultrasound module 201 and other components while still allowing for the removal of ultrasound module 201. The connectors are discussed with greater detail later and with reference to

In some embodiments, power supply module 301 includes components which facilitate the modularity of portable ultrasound system 100. In one embodiment, power supply module 301 includes a floating connector 303. Floating connector 303 allows ultrasound module 201 to connect to power supply module 301. This connection may allow for power and/or data transfer between power supply module 301 and ultrasound module 201. Floating connector 303 is configured to move three dimensionally relative to power supply module 301 while still being electrically connected to the components of power supply module 301. This is described in more detail with reference to
Advantageously, the movement of floating connector 303 helps to align and connect ultrasound module 201 to power supply module 301 and thus allows for easier insertion of ultrasound module 201 into portable ultrasound system 100. Floating connector 303 may allow for connection between ultrasound module 201 and power supply module 301 to occur within a greater range of alignment tolerances as floating connector 303 is allowed to move relative to power supply module 301. Thus, less precision in the alignment of ultrasound module 201 and power supply module 301 may be required when inserting an ultrasound module 201 into portable ultrasound system 100. This may make it easier for a user to inset ultrasound modules 201 (e.g., with less attention to accuracy, greater speed, etc.). Advantageously, floating connector 303 may also reduce the stress experienced by connectors on the ultrasound module 201 by helping to guide the connectors into place with floating connector 303 while moving relative to power supply module 301. The floating nature of floating connector 303 may increase the alignment tolerances of the two sets of connectors (e.g., on ultrasound module 201 and power supply module 301) easing the connection process and helping to reduce stress. Advantageously, the reduced stress experienced by the connectors due to floating connector 303 may increase the life cycle of connectors on one or more of the ultrasound module 201 and the power supply module 301. This may reduce the amount of repair and/or maintenance performed on ultrasound module 201 and/or power supply module 301 and increase the amount of uptime for portable ultrasound system 100.
In some embodiments, power supply module 301 includes additional connectors and/or connections. For example, power supply module 301 may be connected to both ultrasound module 201 and main circuit board module 401. Power supply module 301 may be connected to ultrasound module 201 with floating connector 303. In some embodiments, power supply module 301 is also connected to main circuit board module 401 with a second floating connector 303. In other embodiments, power supply module 301 is connected to main circuit board module 401 with a fixed connector. In still further embodiments, power supply module 301 may be connected to main circuit board 401 with fixed connections and/or wiring. For example, power supply module 301 and main circuit board 401 may be configured so as to not be separable during normal operation. During repair and/or replacement of components, power supply module 301 and main circuit board 401 may be separated. For example, connectors and/or wiring could be de-soldered from one or both of the modules.
In some embodiments, power supply module 301 may be configured so as to be a replaceable and/or upgradable module. Power supply module 301 may be a contained module containing power supply components. This may allow for the removal of a power supply module 301 and for power supply module 301 to be replaced. Advantageously, the contained nature of power supply module 301 may allow for easy replacement of a power supply module 301 in order to repair or upgrade the power supply components of portable ultrasound system 100. This may allow for quick repairs to be made and for upgrades to be made in order to support other components of portable ultrasound system 100. For example, if an ultrasound module 201 is replaced with an ultrasound module 201 requiring different power specifications (e.g., a different operating voltage), then power supply module 301 may also be replaced to support the new ultrasound module 201. The modular nature of power supply module 301 may facilitate the repair or replacement of power components of portable ultrasound system 100. In some embodiments, power supply module 301 may be removed from portable ultrasound system 100 using a release lever. In other embodiments, power supply module 301 is attached to portable ultrasound system 100 (e.g., a frame and/or cover of the system) using screws, nuts and bolts, adhesive, and/or other fasteners.

In other embodiments, release lever 701 only applies force to ultrasound module 201 during a portion of full range of motion of release lever 701. Release lever 701 may have one or more ranges during which no force is applied to ultrasound module 201 while release lever 701 is rotated through the ranges. For example, release lever 701 may rotate through zero degrees to twenty degrees without an internal (e.g., within main housing 150) portion of release lever 701 contacting or otherwise applying force to ultrasound module 201. Advantageously, this may prevent unintended removal of ultrasound module 201. A user may have to rotate release lever 701 beyond a certain threshold angle in order to start applying force to ultrasound module 201 and thereby ensure that the user intends to disconnect ultrasound module 201. In some embodiments, release lever 701 may be configured such that no force is applied to ultrasound module 201 as release lever 701 is rotated from a partially actuated to a fully actuated position. For example, release lever 701 may be configured such that the portion of release lever 701 internal to main housing 150 does not contact or otherwise apply force to ultrasound module 201 as release lever 701 is rotated between seventy and ninety degrees relative to main housing 150. Advantageously, this may ensure that ultrasound module 201 is still held in place and prevents ultrasound module 201 from unintentionally slipping or falling out of portable ultrasound system 100. Release lever 701 may be configured to prevent ultrasound module 201 from falling out of portable ultrasound system 100 as described above while still ensuring that enough force is applied to ultrasound module 201 for a sufficient range of rotation to allow a user to grab a partially extended ultrasound module 201.

Positioning of the lower portion (e.g., portion within main housing 150) relative to the upper portion (e.g., portion extending from main housing 150 and/or covered by release lever access door 703) may determine at what angle of rotation of release lever 701 force is applied to ultrasound module 201. For example, if the lower portion of release lever 701 is configured to be in contact with ultrasound module 201 while release lever 701 has rotated zero degrees relative to main housing 150, then any rotation of release lever 701 will begin to apply force to ultrasound module 201. The lower portion of release lever 701 may alternatively be positioned such that it is not in contact with an inserted ultrasound module 201 while release lever 701 has not been rotated. Depending on the angle formed by the lower portion of release lever 701 relative to the upper portion, the angle of rotation at which release lever 701 begins to apply force to ultrasound module 201 may be adjusted. By altering this angle, the above described functions of release lever 701 may be achieved.
In some embodiments, main housing 150 may include one or more shoulders 151. Shoulder 151 may guide, locate, prevent over insertion, and/or otherwise position ultrasound module 201. As illustrated in
In other embodiments, axel 709 is fixedly coupled to release lever 701. Axel 709 may be one or more protrusions from release lever 701. For example, axel 709 may be formed as an integral part of release lever 701 (e.g., by injection molding, milling, or another manufacturing technique). Axel 709 may be attached to release lever 701 using screws, nuts and bolts, adhesive, and/or other fasteners. Axel 709 may alternatively or in addition to the above techniques be inserted into a sleeve of release lever 701 such that the sleeve and axel 709 from an interference fit. Axel 709 may rotate freely within opening 711 of flange 715. For example, opening 711 and axel 709 may have a running fit. In some embodiments, opening 711 of flange 715, and/or axel 709 may be configured to support the rotation of axel 709 within opening 711. For example, a bearing assembly may be used to support axel 709 with flange 711.
In some embodiments, release lever 701 includes a cam portion 713. Cam portion 713 may function as a cam and facilitate the transformation of the rotational movement of release lever 701 into linear motion for pushing (e.g., disconnecting and ejecting) ultrasound module 201. The contact between cam portion 713 and ultrasound module 201 may be used to create linear motion of ultrasound module 201. Advantageously, this linear motion of ultrasound module 201 may reduce stress on the connectors of ultrasound module 201, power supply module 301, and/or main circuit board module 401 during disconnection of ultrasound module 201. In some embodiments, cam portion 713 has a cam profile to create uniform linear motion of ultrasound module 201 during the rotation of release lever 701 while disconnection ultrasound module 201. In additional embodiments, cam portion 713 has a cam profile which is configured to reduce stress and/or wear on release lever 701 and/or ultrasound module 201 due to the contact between release lever 701 and ultrasound module 201. Advantageously, this may increase the life span of release lever 701 and/or ultrasound module 201. Cam portion 713 may also provide an advantage to a user of portable ultrasound system 100 by creating uniform linear motion throughout the rotation of release lever 701. This may provide a user with predictable and repeatable disconnection of ultrasound module 201. In further embodiments, cam portion 713 may have a different cam profile. For example, cam portion 713 may have a cam profile which produces more linear motion for each degree of rotation of release lever 701. In other embodiments, cam portion 713 may have a cam profile which produces less linear motion per degree of release lever 701 rotation. This may allow for a release lever 701 with a greater range of rotation (e.g., 170 degrees).
In some embodiments, cam portion 713 extends for the entire length and/or width of the lower portion of release lever 701. In other embodiments, cam portion 713 is a portion of the lower portion of release lever 701.
In some embodiments, cam portion 713 has a cam profile which is configured to effect the range of motion of release lever 701 during which force is applied to ultrasound module 201. Cam portion 713 may have a profile which creates or helps to create the functions described above with reference to
Advantageously, the configuration of cam portion 713 and/or the configuration of the upper and/or lower portions of the release lever 701 may provide a mechanical advantage to a user such that reduced force is required to disconnect an ultrasound module. This may make it easier for a user to disconnect and/or eject ultrasound module 201 from portable ultrasound system 100. This may also enhance the portability and modularity of portable ultrasound system 100 by making it easier to swap ultrasound modules 201 depending on the application and/or other needs of the user.
With reference to
In some embodiments, ultrasound module 201 is disconnected and/or ejected by the above described techniques in response to a user input received through a dedicated input mechanism. For example, the dedicated input mechanism may be a button, capacitive sensor, switch, knob, and/or other input device. The dedicated input mechanism may be accessed through a release lever access door 703 or like component. In other embodiments, the dedicated input mechanism is located elsewhere on portable ultrasound system 100. For example, the dedicated input mechanism may be located on a side of portable ultrasound system 100, included in a keyboard, located within main housing 150, be located adjacent to a display and/or input screen, be included in a cover or housing of main screen 130, or otherwise positioned in or on portable ultrasound system 100.
In other embodiments, ultrasound module 201 is disconnected and/or ejected by the above described techniques in response to a user input received through a user interface of portable ultrasound system 100. For example, the user interface of portable ultrasound system 100 may include an input element (e.g., a button, slider, radio button, field, or other graphical user interface element) which allows a user to disconnect and/or eject ultrasound module 201. Continuing the example, a user may provide an input using a button of the user interface and touchscreen 120 which causes portable ultrasound system 100 to activate an electromechanical system and thereby disconnect and/or eject ultrasound module 201.
In some embodiments, release lever 701 may include an interlock system. The interlock system may prevent disconnection and/or removal of ultrasound module 201. For example, the interlock system may prevent removal of ultrasound module 201 during inappropriate times (e.g., while imaging is in process, while data is being exchanged between ultrasound module 201 and main circuit board module 401, etc.) to prevent damage to components and/or loss of data. The interlock system may allow for removal of ultrasound module 201 when doing so will not cause harm. In one embodiment, the interlock system is controlled by main circuit board module 401. When main circuit board module 401 detects that it is not safe to disconnect ultrasound module 201 main circuit board module 401 may engage a normally open interlock mechanism. In other embodiments, the interlock mechanism, is normally closed (e.g., engaged to prevent removal of ultrasound module 201) and main circuit board module 401 disengages the interlock mechanism when it determines that it is safe to remove ultrasound module 201.
In some embodiments, the interlock mechanism may not be a physical mechanism but may be expressed in programming of portable ultrasound system 100. For example, a portable ultrasound system 100 may be programmed such that an electromechanical system which disconnects and/or ejects ultrasound module 201 may not be activated unless main circuit board module 401 determines that it is safe to disconnect and/or eject ultrasound module 201.
In other embodiments, the interlock mechanism is or includes physical components. For example, the interlock mechanism may be a lock or other physical component which impedes or prevents movement of release lever 701 when engaged. In further embodiments, the interlock mechanism may be a lock or other components which prevents a user from opening release lever access door 703 when engaged. In other embodiments, components other than main circuit board module 401 may perform the above described functions. For example, components of ultrasound module 201 (e.g., processors, memory, integrated circuits, etc.) may perform the tasks described above with reference to main circuit board module 401. In some embodiments, release lever access door 703 acts as an interlock mechanism.

In some embodiments, main housing 150 includes one or more shoulders 151. As previously discussed shoulder 151 may guide, locate, prevent over insertion, and/or otherwise position ultrasound module 201. Shoulders 151 may position ultrasound module 201 laterally and/or along the axis of insertion of ultrasound module 201. When ultrasound module 201 comes into contact with one or more shoulders 151, it is prevented from moving further in that direction. Advantageously, this may prevent excessive force, due to over insertion, on connectors of portable ultrasound system 100. This may also provide an advantage by aligning connectors on ultrasound module 201 with those on power supply module 301 and/or main circuit board module 401.

In other embodiments, ultrasound module 201 is held in place by additional components rather than by a fit with frame 801. In one embodiment, frame 801 and/or ultrasound module 201 may include a friction material. The friction material may prevent ultrasound module 201 from sliding relative to frame 801 unless sufficient force is applied to overcome the static friction force created by the friction material. In other embodiments, ultrasound module 201 may be prevented from sliding due to plastically deformable protrusions included on frame 801 and/or ultrasound module 201. The protrusions may keep ultrasound module 201 from moving relative to frame 801 until a sufficient force is applied to plastically deform the protrusion. In additional embodiments, release lever 701 may include a component which latches to or otherwise connects to ultrasound module 201. Ultrasound module 201 may be releasably connected to release lever 701 which prevents movement of ultrasound module 201 relative to frame 801. When release lever 701 is actuated, release lever 701 may unlatch from ultrasound module 201. In some embodiments, a combination of the above described components and/or additional components may be used to prevent ultrasound module 201 from unintentionally sliding out of portable ultrasound system 100.

In one embodiment, ultrasound module 201 includes female fixed connector 215 for connecting to main circuit board module 401. Main circuit board module 401 may include a male fixed connector for connecting to ultrasound module 201 via female fixed connector 215.
Ultrasound module 201 may also include male floating connector 217. In one embodiment, male floating connector 217 connects ultrasound module 201 to a female floating connector included in power supply module 301. In some embodiments, male floating connector 217 does not float (e.g., does not move relative to ultrasound module 201 to facilitate the connection of misaligned connectors), but is instead configured to connect to a female floating connector included in power supply module 301. The female floating connector may float as described herein with reference to
Advantageously, the features described herein with respect to
In some embodiments, ultrasound module 201 and/or other components of portable ultrasound system 100 may have different connections, a greater number of connections, a lesser number of connections, and/or other configurations than are described herein with reference to

In some embodiments, the fixed connector pair include elements to facilitate connection between female fixed connector 215 and male fixed connector 407. These elements may align the two connectors and/or otherwise correct misalignment of the two connectors as ultrasound module 201 is inserted and/or connected to portable ultrasound system 100. In some embodiments, female fixed connector 215 includes one or more guide slots 219. Guide slots 219 may correspond to one or more guide shafts 421 of male fixed connector 407. Guide slot 219 may be configured to receive a guide shaft 421 such that guide slot 219 may receive guide shaft 421 when female fixed connector 215 and male fixed connector 407 are misaligned. For example, guide slot 219 may have an outer radius greater than the radius of guide shaft 421. As guide shaft 421 is inserted into guide slot 219, the female fixed connector 215 and male fixed connector 407 may be aligned. In some embodiments, the radius of guide slot 219 decreases along the depth of guide slot 219. As guide shaft 421 travels deeper into guide slot 219 the decreasing radius of guide slot 219 may center guide shaft 421 within guide slot 219. As guide shaft 421 is centered in guide slot 219, female fixed connector 215 and male fixed connector 407 may be aligned. Advantageously, this allows misaligned connectors to be aligned as ultrasound module 201 is inserted. In some embodiments, guide shaft 421 has a decreasing radius extending outward from male fixed connector 407. This may allow for easier alignment of guide shaft 421 and guide slot 219. Contacts 223 of female fixed connector 215 may be brought into alignment with contacts 423 of male fixed connected 407 by one or more of these features.
In some embodiments, female fixed connector 215 includes guide shafts 221 which correspond to guide slots 419 on male fixed connector 407. As explained above, guide shafts 221 and the corresponding guide slots 419 may align female fixed connector 215 and male fixed connector 407 as guide shafts 221 are inserted into guide slots 419. Guide shafts may be inserted into guide slots as ultrasound module 201 is inserted into portable ultrasound system 100.
In some embodiments, contacts 423 of male fixed connector 407 and contacts 223 of female fixed connector 215 are configured to tolerate some misalignment between male fixed connector 407 and female fixed connector 215. For example, contacts 223 of female fixed connector 215 may include chamfered features which align the contacts 423 of male fixed connector 407 as they are inserted. Contacts 423 of male fixed connector 407 may also be configured to align with contacts 223 of female fixed connector 215. For example, connectors 423 of male fixed connector 407 may be sized to fit within female fixed connector 215.
In some embodiments, male fixed connector 407 and/or female fixed connector 215 are configured to provide friction force to secure ultrasound module 201 within portable ultrasound system 100 when inserted. The friction force may prevent or assist in preventing ultrasound module 201 from disconnecting from the other components of portable ultrasound system 100 except by the function of release lever 701. For example, the guide shaft and guide slot features described above may be sized such that an inserted ultrasound module 201 is held in place by the friction between a guide shaft and the guide slot into which the guide shaft has been inserted. Once a guide shaft has been aligned by and inserted fully into a guide slot, the inner radius of the guide slot and the guide shaft may form an interference fit or other type of fit to provide friction force. The fit may still allow removal of the guide shaft from the guide slot in response to force provided by release lever 701.
Female fixed connector 215 and the associated features have been described as corresponding to ultrasound module 201 and male fixed connector 407 and the associated features have been described as corresponding to main circuit board module 401. However, this is illustrative only. In other embodiments, fixed connectors (male and/or female) may be used on other or additional components. For example, male fixed connector 407 may be located on ultrasound module 201 and female fixed connector 215 may be located on main circuit board module 401. In further embodiments, fixed connectors may be used to couple ultrasound module 201 and other components of portable ultrasound system 100 (e.g., power supply module 301).

In some embodiments, male floating connector 217 includes one or more types of contacts to establish electrical communication with the contacts of female floating connector 307. For example, male floating connector 217 may include pin contacts 227. Pin contacts 227 may be configured to come into electrical contact with pin slot contacts 327 of female floating connector 307 when male floating connector 217 is connected to female floating connector 307. Pin slot contacts 327 and pin contacts 227 may be made of a conductive material to allow electrical communication between both sets of contacts. In some embodiments, pin slot contacts 327 include chamfered openings to the slots which assist in the alignment of pin contacts 227 and pin slot contacts 327. The reducing openings of pin slot contacts 327 may allow pin contacts 227 to be inserted and then centered with pin slot contacts 327 as the size of the opening decreases along the depth of slot contacts 327.
Male floating connector 217 may include one or more plate contacts 225. In some embodiments, plate contacts 225 are configured to push outward so as to be in contact with plate slot contacts 325 of female floating connector 307 when male floating connector 217 is inserted. For example, plate contacts 225 may be spring loaded so as to push outward against plate slot contacts 325, positioned such that they plastically deform and push against plate slot contacts 325 when inserted, or otherwise configured to form an electrical connection with plate slot contacts 325. In some embodiments, plate slot contacts 325 are chamfered to aid in the alignment of plate contacts 225 with plate slot contacts 325. The electrical communication formed by contacts on male floating connector 217 and female floating connector 307 may allow for the transfer of electrical power, control signals, data, and/or other information between ultrasound module 201 and power supply module 301. In one embodiment, electrical power is provided from power supply module 301 to ultrasound module 201 using plate contacts 225 and plate slot contacts 325. In further embodiments, data, control signals, and/or other information is transferred between ultrasound module 201 and power supply module 301 using pin contacts 227 and pin slot contacts 327.
In some embodiments, the pair of floating connectors includes guiding features which assist in aligning female floating connector 307 with male floating connector 217. For example, female floating connector 307 may include one or more guide protrusions 331. Guide protrusions may extend from female floating connector 307 and be chamfered. During connection of female floating connector 307 and male floating connector 217, guide protrusions 331 may be received by guide sections 231 of male floating connector 217. Guide sections 231 may also be chamfered. As the size of the above features is reduced along the depth of the guide feature, guide protrusions 331 may be inserted into guide sections 231 while misaligned. As guide protrusions 331 are inserted along the depth of guide section 231 the reducing size (e.g., due to the chamfer) of guide section 231 aligns male floating connector 217 with female floating connector 307. In some embodiments, the edge of housing 229 of male floating connector 217 is also chamfered. This may allow the chamfered main body 329 of female floating connector 307 to align with housing 229 of male floating connector 217 as described with reference to guide protrusions 331 and guide section 231.
In some embodiments, male floating connector 217 and/or female floating connector 307 are configured to provide friction force to secure ultrasound module 201 within portable ultrasound system 100 when inserted. The friction force may prevent or assist in preventing ultrasound module 201 from disconnecting from the other components of portable ultrasound system 100 except by the function of release lever 701. For example, the guide protrusion, guide section, housing, and/or main body features described above may be sized such that an inserted ultrasound module 201 is held in place by the friction between the features on male floating connection 217 and the features on female floating connector 307. For example, the fit between guide protrusion 331 and guide section 231 may form an interference fit or other type of fit to provide friction force. The fit may still allow removal of the guide shaft from the guide slot in response to force provided by release lever 701.
In further embodiments, female floating connector 307 floats in relation to its corresponding component (e.g., power supply module 301). Female floating connector 307 may have six degrees of freedom in relation to power supply module 301. This may allow female floating connector 307 to translate vertically, horizontally, and/or along the depth of power supply module 301. Female floating connector 307 may also pitch, roll, and/or yaw in relation to power supply module 301. Advantageously, this movement may allow female floating connector 307 to align itself with a male floating connector 217 that is initially misaligned. The floating nature of female floating connector 307 may augment the alignment features previously discussed such that a connection may be made between connectors which are misaligned to a greater degree. In some embodiments, female floating connector 307 is constrained in its six degrees of freedom by the features which allow it to float and/or the features connecting it to power supply module 301.
In some embodiments, female floating connector 307 is attached to power supply module 301 with one or springs which provide female floating connector 307 with six degrees of freedom. For example, a spring at each corner of female floating connector 307 may connect female floating connector 307 to power supply module 301. In some embodiments, the springs may run within guiding features which constrain the movement of female floating connector 307. For example, each spring may be positioned within a hollow shaft which runs within a slot connected to power supply module 301. The slot may be sized larger than the shaft to allow the shaft to move relative to the slot thereby giving female floating connector 307 six degrees of freedom. The springs may cause female floating connector 307 to return to an initial position and/or provide a force which assists in the alignment process (e.g., by brining female floating connector 307 into alignment with male floating connector 217 as the two connectors are aligned and/or connected). In other embodiments, plastically deformable features connect female floating connector 307 with power supply module 301. For example, female floating connector 307 may be attached to power supply module 301 by a flexible gasket. The gasket may position female floating connector 307 relative to the housing of power supply module 301 (e.g., the gasket may be positioned around female floating connector 307 and between female floating connector 307 and an opening in the housing of power supply module 301). Other techniques may be used to give female floating connector 307 six or fewer degrees of freedom relative power supply module 301.
In some embodiments, female floating connector 307 may include flexible features which connect pin slot contacts 327 and/or plate slot contacts 325 to fixed components of power supply module 301. Advantageously, this may allow for female floating connector 307 to move relative power supply module 301 without causing damage to the contacts or disconnecting the contacts from other components of power supply module 301. For example, pin slot contacts 327 and/or plate slot contacts 325 may be connected to other components of power supply module 301 with flexible wire long enough to allow movement of female floating connector 307 and the contacts therein. When connected, the contacts of female floating connector 307 and male floating connector 217 may allow for the communication of electrical power and/or data between ultrasound module 201 and power supply module 301. For example, data may be electrically communicated between ultrasound module 201 and power supply module 301 using the connection formed by pin contacts 227 and pin slot contacts 327. Continuing the example, electrical power may be electrically communicated between ultrasound module 201 and power supply module 301 using the connection formed by plate contacts 225 and plate slot contacts 325.
Female floating connector 307 and the associated features have been described as corresponding to power supply module 301 and male floating connector 217 and the associated features have been described as corresponding to ultrasound module 201. Additionally, female floating connector 307 has been described as floating and male floating connector 217 as fixed. However, this description is illustrative only. In other embodiments, floating connectors (male and/or female) may be used on other or additional components. For example, female floating connector 307 may be located on ultrasound module 201 and male floating connector 217 may be located on power supply module 301. In further embodiments, fixed connectors may be used to couple ultrasound module 201 and other components of portable ultrasound system 100 (e.g., power supply module 301). Additionally, both floating connectors float (e.g., have six degrees of freedom) in some embodiments. In other embodiments, male floating connector 217 floats and female floating connector 307 is fixed.

Heat shield 813 may be a substance, material or materials, and/or layer included in portable ultrasound system 100 which absorbs, dissipates, and/or reflects heat. Absorbed heat may be directed away from protected components by the heat shield 813. Heat shield 813 may operate on the principles of convection, conduction, reflection, absorption, or other thermodynamic or heat transfer principles for preventing heat from reaching a shielded component or components. In some embodiments, heat shield 813 includes or is an insulating material. Materials making up heat shield 813 may include heat conductive materials (e.g., copper, aluminum, etc.), heat reflective materials (e.g., foils, radiant barriers, metalized fabrics, laminate films, or other materials suitable for reflecting heat and/or radiation), insulating materials (e.g., ceramics, fiberglass, foams, polymers, fiber based materials, or other materials suitable for impeding heat transfer), backing materials (cloth, fabric, paper, metals, ceramics, of other materials suitable for providing mechanical support to the materials described herein), and/or other materials for shielding components from a source of heat. In some embodiments, heat shield 813 may include an air space (e.g., as a layer between layers of other materials) and/or be positioned relative to other components of portable ultrasound system 100 such that an air space is created between heat shield 813 and the component to be shielded and/or the heat source. In additional embodiments, heat shield 813 is or includes an ablative heat shield and/or a thermal soak heat shield.
With reference to
Advantageously, this positioning of heat shield 813 may shield one or more of touchscreen 120, touchpad 110, and a keyboard from heat generated by components of portable ultrasound system 100. This may protect these or other components from damage caused by exposure to heat and/or improve the user experience by providing user inputs which are not hot or warm to the touch. Particularly, heat shield 813 may provide an advantage by preventing heat generated by ultrasound module 201 from increasing the temperature of user input device touchscreen 201. This may provide a particular advantage as components of ultrasound module 201 may produce a larger amount of heat or a larger amount of heat than other components of portable ultrasound system 100. Additionally, heat shield 813 may allow for portable ultrasound system 100 to be packaged in such a way as to support the modularity of the system. For example, heat shield 813 may allow for ultrasound module 201 to be located below components such as touchscreen 120 without the heat from ultrasound module 201 creating adverse effects in other components. Heat shield 813 may also allow the overall size of portable ultrasound system 100 to be reduced (e.g., the system may be thinner by allowing ultrasound module 813 to be closer to touchscreen 120) thus increasing the portability of the system.
In other embodiments, heat shield 813 extends to shield touchpad 110 and/or a keyboard. This may provide an advantage of decreasing the temperature of these components felt by a user and/or increasing the performance or durability of these components. In further embodiments, a plurality of heat shields 813 are used to protect components of portable ultrasound system 100.

In some embodiments, heat shield 813 is integrated into ultrasound module 201. For example, ultrasound modules 201 may include one or more heat shields 813 to prevent or mitigate heat transfer from ultrasound module 201 to other components of portable ultrasound system 100. In one embodiment, heat shield 813 is attached to an outer surface of ultrasound module 201. For example, heat shield 813 may be attached to or otherwise coupled to heat sink 207 of ultrasound module 201. Heat shield 813 may be attached using screws, nuts and bolts, adhesive, and/or other fasteners. In other embodiments, heat shield 813 is integral or internal to ultrasound module 201. For example, heat shield 813 may be included in or take the place of a heat sink 207. Alternatively and/or additionally, heat shield 813 may be included within ultrasound module 813. For example, heat shield 813 may be located within a housing of ultrasound module 201. In some embodiments, the housing of ultrasound module 201 may include heat shield 813 or be replaced by heat shield 813 or be made of a material with properties which allow it to function as a heat shield.
In some embodiments, the heat management system of portable ultrasound device includes one or more fans. Fans may provide a source of convection cooling for components of portable ultrasound device 100. The fans may provide the same or similar advantages described above with respect to the heat management system of portable ultrasound device 100. For example, fans may improve the effectiveness of air paths as relates to keeping components of portable ultrasound system 100 cool.

The present disclosure contemplates methods, systems, and program products on any machine-readable media for accomplishing various operations. The embodiments of the present disclosure may be implemented using existing computer processors, or by a special purpose computer processor for an appropriate system, incorporated for this or another purpose, or by a hardwired system. Embodiments within the scope of the present disclosure include program products comprising machine-readable media for carrying or having machine-executable instructions or data structures stored thereon. Such machine-readable media can be any available media that can be accessed by a general purpose or special purpose computer or other machine with a processor. By way of example, such machine-readable media can comprise RAM, ROM, EPROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to carry or store desired program code in the form of machine-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer or other machine with a processor. When information is transferred or provided over a network or another communications connection (either hardwired, wireless, or a combination of hardwired or wireless) to a machine, the machine properly views the connection as a machine-readable medium. Thus, any such connection is properly termed a machine-readable medium. Combinations of the above are also included within the scope of machine-readable media. Machine-executable instructions include, for example, instructions and data which cause a general purpose computer, special purpose computer, or special purpose processing machines to perform a certain function or group of functions.
Although the figures may show a specific order of method steps, the order of the steps may differ from what is depicted. Also two or more steps may be performed concurrently or with partial concurrence. Such variation will depend on the software and hardware systems chosen and on designer choice. All such variations are within the scope of the disclosure. Likewise, software implementations could be accomplished with standard programming techniques with rule based logic and other logic to accomplish the various connection steps, processing steps, comparison steps and decision steps.
