  • Patent number: 11446810
    Abstract: A robotic assistant comprises a plurality of sensors in a compact and unobtrusive form. One or more sensors may be emplaced upon a mast that may be selectively raised and lowered. The mast allows the robotic assistant to acquire images or other sensor data from a greater height, without substantially increasing the bulk of the robotic assistant. For ease of transport from one floor to another or from one building to another, the robotic assistant may deploy a handhold that a human may use to pick up and carry the robotic assistant. Floor characterization sensors may be used to determine characteristics of the floor such as if the floor is wet or dry. The robotic assistant may be used to provide a user with access to network services, to monitor a facility, provide telepresence services, and so forth.

  • Patent number: 11345052
    Abstract: An extensible mast device allows a payload to be supported at a controllable distance from a supporting device. A motor driving a flexible strip provides a force through the flexible strip to extend the mast. The extended strip may have a curved cross section that provides some rigidity. A set of telescoping sections may enclose the strip. One or more of the sections may be flexible. In the event of an impact between the extensible mast and an object, such as a user, the flexible section and the strip yield to the impact and collapse. The extensible mast may be easily reset by lifting it back to a vertical position, with the flexible strip reasserting the curved cross section and the flexible sections resuming substantially the same shape as before the impact. A robot may use the extensible mast to elevate cameras or other sensors to a higher vantage point.

  • Patent number: 9989980
    Abstract: Various examples are directed to providing thermal management to a computing device. The computing device may receive temperature state data describing a temperature state of the computing device. The temperature state may comprise a first temperature value at a first location at the computing device. The computing device may also receive use state data describing a first use state of the computing device. The first use state may comprise an initial operating condition of a first component of the computing device and an initial operating condition of a second component of the computing device. The computing device may determine that at least one temperature value at the computing device is out-of-range and select a second use state for the computing device. The second use state may comprise at least one of a new operating condition for the first component or a new operating condition of the second component.

  • Patent number: 9615011
    Abstract: An electronic device includes an elongated tubular housing. One or more electronic components are coupled to a chassis disposed in a cavity of the tubular housing. A pair of elongated channels are positioned on opposite sides of the chassis and between the chassis and a sidewall of the tubular housing. The channels are tapered or wedge-shaped along their lengths. During assembly, one of the channels may be slid longitudinally along the other, causing the channels to expand laterally, due to their wedge shape, to secure the chassis in the tubular housing. The chassis and the pair of channels provide a thermally conductive path to dissipate heat. During use, heat generated by the electronic components is transmitted radially outward from the electronic components, through the chassis and the pair of channels, and through the tubular housing to the exterior of the portable electronic device.

  • Patent number: 9213424
    Abstract: A stylus device including a first end or active end for writing and interacting with a touchscreen of a computing device, and a second end or passive end for using an erase function with the touchscreen of the computing device. This allows a user to write or interact with a computing device with one end of the stylus device and simply turn the stylus device over and erase without having to select an eraser function from a menu on the computing device. In this manner, the stylus device provides a more traditional method of writing and erasing, similar to that of traditional pencils.

  • Patent number: 8971049
    Abstract: A portable electronic device, a peripheral expansion module and methods for assembling a peripheral expansion module onto a portable electronic device are provided herein. The portable electronic device may comprise a main housing unit having a front cover and a back cover which, when coupled together, enclose internal components of the portable electronic device. The peripheral expansion module, comprising one or more peripheral devices coupled within or on a peripheral module housing, may be securely integrated with the portable electronic device. A majority of the peripheral expansion module may be positioned outside of the main housing unit along one side of the portable electronic device. In some embodiments, the peripheral expansion module includes a pair of rails, which extend out from within an interior of the module housing for attachment via one or more mechanical fasteners to an interior surface of the main housing unit of the portable electronic device.

  • Patent number: 7941231
    Abstract: An electronic device is provided that is able to detect noise to which the electronic device is exposed and an internal temperature of the device. The device contains a cooling unit to cool at least a portion of the electronic device and a subsystem coupled to the microphone and/or a thermal sensor and further coupled to the cooling unit. The cooling unit adjusts according to the detected noise and internal temperature. A method for cooling an electronic device is also provided. The method comprises monitoring the noise of the device's ambient environment, monitoring an internal temperature of the device, and actuating a user interface. The method provides for cooling the device by adjusting fan speed, clock speed, or power supply voltage applied to the device based on the noise of the ambient environment, an internal temperature of the device, and actuation of the user interface.

  • Publication number: 20090201636
    Abstract: A portable computer that is ergonomic and solvent resistant is disclosed. The computer may have an exterior surface that is made from a soft polymer, so that it will shield a user from exposure to heat while providing a positive tactile feel and shielding the computer from impact. The computer may comprise a number of input output devices with distinct controls arranged about the body of the computer so that a user may comfortably operate each the devices with one hand. The housing of the computer may be sealed, so that it will be resistant to liquid and particulate infiltration, and may be easily wiped clean and disinfected.
