摘要： An apparatus includes an eyeglass frame, a first antenna, a second antenna, and a parasitic element. The eyeglass frame can include at least one rim. The first antenna can be attached to the eyeglass frame. The second antenna can be attached to the eyeglass frame. The second antenna can be disposed on a first side of the at least one rim. The parasitic element can be attached to the eyeglass frame. The parasitic element can be on a second side of the at least one rim. The second side of the at least one rim can be opposite from the first side. A distance from the first antenna to the second antenna can be greater than a distance from the first antenna to the parasitic element. The distance from the first antenna to the second antenna can be greater than a distance from the second antenna to the parasitic element.

摘要： The present disclosure provides for detection of input to a wireless device, such as earbuds or other wearable devices, based on RF signals between the earbuds and/or between an earbud and other devices, such as a host device. For example, gestures may be detected using signal strength, such as by using a received signal strength indicator (RSSI), between two earbuds and/or between an earbud and a host device.

摘要： An antenna includes a planar dielectric substrate having opposing first and second surfaces, a ground plane disposed at the first surface, the ground plane composed of conductive material, a radiating plane disposed at the second surface and composed of conductive material. The radiating plane implements a plurality of unit cells, with each unit cell having a corresponding section of the conductive material of the radiating plane that is formed in a specified shape, the specified shape including a first portion forming a load inductor and second portion forming a radiating patch electrically coupled to the load inductor. Each unit cell further includes at least one via electrically coupling the load inductor to the ground plane.

摘要： An antenna is provided for a wearable personal computing device, such as an earbud. The antenna integrates with other components of the wearable device, such as an input control. For example, the antenna may at least partially surround a portion of a touchpad input at a surface of the device that is exposed when the device is worn. In one example, the antenna shares a ground plane with the touchpad. In another example, the antenna includes two nested traces, wherein a first trace is connected to ground and a second trace is connected to an antenna feed.

摘要： Various arrangements for remote sensing using cross-circular polarization are presented. In some embodiments, an RFID (Radio Frequency Identification) emitter is present that emits circular-polarized RF (Radio Frequency) waves having a first polarization. A circular-polarized passive RFID tag may be present that is configured to receive, modulate, and output circular-polarized RF waves that have a second polarization opposite from the first polarization.

摘要： A system and method is provided for improving signal quality in communications among fully wireless systems including a host device in wireless communication with a primary accessory which further wirelessly communicates with a secondary accessory. The host device generates information for use by the primary accessory in determining which channels have interference and should be avoided. The information may include an adaptive frequency hopping (AFH) channel map for communications between the host and the primary device, from which the primary device can infer which frequency bands have interference and generate a second AFH map for communications between the primary accessory and the secondary accessory accordingly. In other examples the information includes the second AFH map generated by the host, for example, based on an out-of-band scan. In further examples, the information includes an indication of channels used by recognized nearby access points.
