摘要： A wearable device comprises an exteriorly positioned first electrode and a reporting capacitor. The first electrode forms a first side of the reporting capacitor, and a second side of the reporting capacitor is formed by skin of a user when the wearable device is worn. An oscillator is configured to output a signal to drive the first electrode at a first frequency. The oscillator is configured such that changes in capacitance at the reporting capacitor adjust the signal output by the oscillator from the first frequency to a second frequency. A frequency-to-voltage converter is configured to generate a voltage representation of the second frequency. A controller determines a change between the first frequency and the second frequency based on the voltage representation and indicates an amount of movement of skin of the user relative to the first electrode based on the determined frequency change.

摘要： A system for facilitating secure communications accesses a secure element in response to determining that an authorized user operates the system. The system causes a light emitter to emit an output light signal for detection by a second system. The output light signal is emitted according to a predefined field of view, which operates as a constraint to prevent devices outside of the field of view from detecting the output light signal. The system also configures the light detector to detect a second output light signal emitted by a second light emitter of the second system. In response to (i) detection of the output light signal by a second light detector of the second system and (ii) detection of the second output light signal by the light detector, the system enables secure communication between the system and the second system.

摘要： A head-mounted mixed-reality (MR) device that is wearable by a user is disclosed. The MR device includes a user-facing display that displays user-directed content. The user-directed content is visible from a first position of a user who is wearing the MR device. The MR device further includes an outward-facing display that displays outward-directed content. The outward-directed content is visible from a second position that is external relative to the position of the user who is wearing the MR device.

摘要： Examples are disclosed that relate to determining a capacitance based on a charge accumulated on a sense capacitor electrode. One example provides a head-mounted device comprising a facial-tracking sensor, a controller, and a charge sensing circuit connected to the facial-tracking sensor. The facial-tracking sensor comprises a sense capacitor electrode configured to be positioned proximate to a surface of a face and form a capacitance based upon a distance between the sense capacitor electrode and the surface of the face, and the controller configured to apply a reference voltage to the sense capacitor electrode. The charge sensing circuit is configured to determine the capacitance of the sense capacitor electrode by determining an amount of charge accumulated on the sense capacitor electrode resulting from the reference voltage.

摘要： Examples are disclosed that relate to sensing a position of a surface proximate to a resonant LC sensor. One example provides a method on a sensing device comprising one or more resonant LC sensors each configured to output a signal responsive to a position of a surface proximate to the resonant LC sensor. The method comprises, for each LC sensor, generating an oscillating signal on an antenna of the resonant LC sensor and detecting a near-field response of the resonant LC sensor at a selected frequency.

摘要： To track an object with radar, and achieve greater than range resolution precision, the phase of a difference signal can be utilized and adjusted as the tracked object crosses between resolution ranges. Changes in the object's distance can be detected with greater than range resolution precision by utilizing the phase. Such changes can iteratively inform the determined distance across multiple phase cycles within a single distance range. As the movement of the object approaches, and then crosses, between resolution ranges, the phase as determined within an origin resolution range can be compared with a coincident phase within the destination resolution range and the difference can then be utilized to adjust the phase as the object then remains within the destination resolution range. Such phase adjustments can be applied across multiple resolution ranges, allowing for the tracking of an object, utilizing radar, while achieving greater than range resolution precision.

摘要： An extended reality headset has light-based communication transceivers coupled to the extended reality headset. The relative position of a remote transceiver with respect to the current position and orientation of the extended reality headset is determined. A line-of-sight is calculated from the light-based communication transceivers to the remote transceiver. The light-based communication transceivers emit a light-based communications beam in accordance with the calculated line-of-sight. The light-based communications beam is adjusted in response to changes to the relative position of the remote transceiver with respect to the current position and orientation of the extended reality headset.
