  • 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.

  • Publication number: 20220161131
    Abstract: This disclosure describes, in part, techniques for controlling network applications. For instance, a remote system may send, over a network, data representing a state of an application to a display device, such as a television. The remote system may then receive, over the network, input data from a control device. The input data may represent one or more inputs received by the control device. Using the input data, the remote system may update the state of the application. The remote system may then send, to the display device, data representing the updated state of the application. In some instances, the remote system may further send, to the control device, audio data representing sound corresponding to the updated state of the application. The control device may synchronize outputting of the sound with the displaying the updated state of the application by the display device.

  • Patent number: 10642361
    Abstract: A haptic electromagnetic actuator for track pad is provided. The actuator includes an array of electromagnets with alternating South and North poles on a first end, each magnet comprising a metal core and an electrical wire around the metal core. The array of magnets is coupled to a base plate on a second end opposite to the first end. The actuator also includes an attraction plate at a distance from the first end of the array of the magnets such that the attraction plate moves toward the magnets when an electrical current flows through the electrical wire around the metal core and moves away from the magnets when the current becomes zero. The array of magnets is configured to form a uniform gap from the attraction plate.

  • Patent number: 10452116
    Abstract: A decision engine executing on an electronic device may determine, using sensor data captured by multiple sensors of the device, whether a user is present in an environment that includes the device. If the user is determined to be present in the environment, the device may transition from a first state to a second state. The first state may be a first power state of the device in which the device is powered off or an idle or dormant state in which the device is powered on but a display of the device is powered off. Correspondingly, the second state may be a second power state of the device in which the device and the display are powered on and content is being rendered on the display. If the decision engine cannot make a determination based on the sensor data, a context engine may adjudicate the user presence determination.

  • Patent number: 9929763
    Abstract: Systems and methods for addressing an inadvertent decrease in transmission energy/power due to triggering a proximity sensor by a cover disposed on a computing device. In an embodiment, a cover sensor may be incorporated into the device. The cover sensor may be used to detect the presence of a cover on the device, as well as whether the cover is in an open or closed position. The output of the cover sensor may then be used to adjust a trigger/proximity threshold of the proximity sensor to account for the presence and position of the cover on the device. In this manner the device may avoid unnecessary power backoff caused by proximity of the cover, rather than proximity of the user. This improves the over the air (OTA) performance of the device, as well as the user experience.

  • Patent number: 9880676
    Abstract: Electronic devices may include force sensitive sensors. The sensor may include a first layer of electrodes, a second layer of electrodes and a deformable dielectric material separating the first layer of electrodes and the second layer of electrodes. A conductive material may be disposed to negate capacitive effects between an object near to or touching the touch surface and the electrodes of the first layer and the electrodes of the second layer. A force applied to the sensor may be detected based at least in part on a change in capacitance between at least one electrode of first layer and at least one electrode of the second layer resulting from deformation of the deformable dielectric material. This disclosure also describes techniques for assembling electronic devices including these components.

  • Patent number: 9779888
    Abstract: An input device configured to communicate with a computing device includes at least one keycap, a support mechanism operably connected to the keycap and configured to move the keycap from a first position to a second position, a feature plate operably connected to the support mechanism, and a sensing member. The sensing member is configured to detect at least one of a change of position of the at least one keycap, a speed of the at least one keycap, an amount of force applied to the at least one keycap, or a location of a finger. The sensing member may be a capacitive sensor. In some embodiments, the input device may not include the support mechanism and the sensing member may be configured to detect the location of a finger regardless whether or not the keycap moves.

  • Patent number: 9679128
    Abstract: A wearable device comprises a first member, a second member that is configured to move relative to the first member, a sensor disposed on the first member, one or more components disposed on the second member, and an authentication module. The sensor is configured to output a sense signal that is indicative of a distance between the sensor and at least one of the one or more components. When the wearable device is worn by a user, the wearable device may be authenticated. The sense signal indicates when at least a portion of the wearable device is opened and/or removed. The wearable device may be de-authenticated based at least in part on the sense signal indicating that a portion of the wearable device has been opened or removed.
