Abstract: The present disclosure provides a metal structure, or antenna radiator, for an accessory that is configured to function as both an antenna and an input control. The device may be a wearable device with a first surface shaped to be in contact with the human body and a second surface shaped to be exposed when the device is being worn. The antenna radiator may be located internally within the housing of the device and coupled to a printed circuit board (“PCB”). The PCB may be located between the antenna radiator and the surface of the housing such that the PCB may shield the antenna radiator from antenna loss due to the human body. An electric field may extend between the PCB and the antenna radiator. The fringe electric field may improve cross-head and cross-body connectivity between the accessory and another device.

Abstract: Techniques and apparatuses are described that implement a smart device-based radar system capable of detecting human vital signs using a compact circularly-polarized antenna. A radar system includes at least one compact circularly-polarized antenna with a patch antenna and a quadrature hybrid coupler. The quadrature hybrid coupler is on a separate plane that is above or below the patch antenna. By vertically stacking the patch antenna with the quadrature hybrid coupler, lateral dimensions of the radar system can be reduced relative to other antenna configurations or designs. The quadrature hybrid coupler can also have a ring-shape design to improve isolation and polarization purity of the compact circularly-polarized antenna relative to a rectangular design. The compact circularly-polarized antenna enables a radar system operating at frequencies between approximately 1 gigahertz (GHz) and 24 GHz to be implemented within a variety of small smart devices.

Abstract: Techniques and mechanisms to provide wireless communication with a body-mountable device comprising a single-loop antenna. In an embodiment, distal ends of the single-loop antenna are disposed on opposite sides of a slit structure, wherein the single-loop antenna extends around a controller configured to provide any of multiple modes of high-frequency communication with the single-loop antenna. Different operational modes each provide for operation of the single-loop antenna with both a proximity-coupled feed structure and a first contact at or near a distal end of the single-loop antenna. In another embodiment, the single-loop antenna forms a hole or a recess structure which is aligned with a sensor or an input/output (I/O) mechanism of the body-mountable device.

Abstract: The technology provides for an electronic device. The electronic device includes a housing, a display cover, and a modular component configured to provide a seal between the housing to the display cover. The modular component is configured to be attached to the housing. Further, the modular component includes a first surface configured to be attached to the display cover. The modular component includes a channel extending along the first surface, where the channel is configured to hold a liquid adhesive that bonds with the display cover. The modular component further includes a radial protrusion disposed on the first surface, the radial protrusion is configured to be in contact with the display cover when the display cover is attached to the housing and to prevent the liquid adhesive from moving out of the channel.

Abstract: 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.

Abstract: An antenna is provided for a wearable personal computing device, such as a smartwatch. The antenna integrates with other components of the wearable device, such as a second antenna. For example, the first antenna may be a coupled loop antenna in proximity to a second antenna that may be a monopole antenna, without causing interference between the two antennas. In one example, the first antenna shares a common ground with the second antenna.

Abstract: Role switch between wirelessly paired master/slave devices may be performed without perceived glitches in audio. The devices negotiate an anchor point, such as a point in time or a point in relation to other events, for performing the role switch. To prepare for the role switch prior to the anchor point, the devices communicate a variety of information, such as information for communicating with the host device after the role switch and information for bit processing after the role switch. The slave device may use such information to serve in the master role, without the host knowing that a role switch occurred.
