摘要： Computing devices and methods for producing vibrations in computing devices are disclosed. In one example, a computing device comprises a chassis that includes a trackpad comprising a printed circuit board. A haptic actuator assembly comprises at least one conductive coil formed on or affixed to the printed circuit board, and at least one magnet rigidly affixed to the chassis. The magnet is spaced from and not mechanically coupled to the at least one conductive coil. A memory stores instructions executable by a processor to receive a haptic event requests, determine that the trackpad is not in use, and at least on condition of receiving the haptic event request and determining that the trackpad is not in use, cause a driver signal to be sent to the conductive coil(s) to cause the at least one magnet to produce user-perceptible vibrations in the chassis beyond the trackpad.

摘要： The wearable device (10) comprises a liveness detection module (103) arranged to detect whether the wearable device (10) is being worn by a user. The wearable device (10) comprises a communicator (107) arranged to transmit a message to a server in response to the liveness detection module (103) detecting that the wearable device (10) is being worn. Prior to the liveness detection module (103) detecting that the wearable device (10) is being worn by a user, the wearable device (10) is arranged to operate in a low power mode.

摘要： A system including a sensor configured so that the presence of a spectacle within a detection range of the sensor is detectable by the sensor when the spectacle includes a predetermined identification structure. The system may further include a control unit configured to receive an information from the sensor and to carry out a predetermined action, upon a condition in which the one or more spectacle lenses may be detected. A method may include detecting the presence of the spectacle within a detection range, and further providing, by the sensor, an information to the control unit. The information may confirm the detection of the spectacle. The method may include carrying out, by the control unit, the predetermined action. A computer program product including instructions to cause the system to execute the steps of the method. A computing device including the sensor and a memory.

摘要： This document describes techniques and systems for radar-based gesture-recognition with context-sensitive gating and other context-sensitive controls. Sensor data from a proximity sensor (108) and/or a movement sensor (108) produces a context of a user equipment (102). The techniques and systems enable the user equipment (102) to recognize contexts when a radar system (104) can be unreliable and should not be used for gesture-recognition, enabling the user equipment (102) to automatically disable or "gate" the output from the radar system (104) according to context. The user equipment (102) prevents the radar system (104) from transitioning to a high-power state (1910) to perform gesture-recognition in contexts where radar data detected by the radar system (104) is likely due to unintentional input. By so doing, the techniques conserve power, improve accuracy, or reduce latency relative to many common techniques and systems for radar-based gesture-recognition.

摘要： This document describes techniques and systems for reducing a state based on sensor data from an Inertial Measurement Unit (IMU) and radar. The techniques and systems use inertial sensor data from an IMU as well as radar data to reduce states of a user equipment, such as power, access, and information states. These states represent power used, an amount of access permitted, or an amount of information provided by the user equipment. The techniques manage the user equipment's states to correspond to a user's engagement with the user equipment, which can save power, reduce unwarranted access, and reduce an amount of information provided when the user is not engaged with the user equipment, thereby protecting the user's privacy.

摘要： The present disclosure describes a method and apparatus that can be used to determine whether an object is in proximity of an electronic device. When an object is not in proximity to the electronic device, the arrangement of two sensors at different distances from the optical emitter results in a higher strength of a reflection signal received in the sensor closer to the optical emitter and a lower strength of a reflection signal received in the sensor further from the optical emitter. The system uses this difference in reflection signals to calculate a ratio between the signals that are being reflected to both sensors, and based on the ratio whether an object is in proximity to the electronic device.
