Detecting the Direction of a UWB Anchor or Tag Using Secondary Radiation

An ultra-wideband (UWB) tag is a device that can be attached to objects to locate them or for other operations such as unlocking a device based on proximity to another device. Common implementations utilize at least three antennas on the device that detects a precise location of a UWB tag. This disclosure describes techniques that leverage secondary radiation caused by the metal case of a laptop (or other devices) to accurately locate a UWB tag while utilizing just two antennas, simplifying hardware design and reducing cost

Guide pin holes for blind mating of connectors

Portable electronics have a charging port to which a user can connect a power cable. In situations where a large number of devices are being charged, e.g., at airports, schools, etc., a clutch of cables forms near the charging station that causes visual clutter and inconvenience. Some devices have a female charging port that can be mated with a male charger without a cable, e.g., by visually aligning the male and female connectors before mating. However, when a user is visually impaired, or where there are several simultaneous devices being charged, the mating of connectors is a difficult task that can cause frustration and connector damage. This disclosure describes techniques that place a guide pin hole next to the charging port of a device. The charger has a male element that fits into the guide pin hole. The guide pin hole makes it convenient to slide a device into a charger

Display Device for Wearable and Other Products

In a watch or other display device, the functionality of the device can be enhanced by using a display that pairs a transparent organic light-emitting diode (TOLED) layer with an underlying display, with the TOLED layer being placed on top of the underlying display instead of below it. There are two main embodiments: (a) one in which the display is a liquid crystal display (LCD) or other transparent display paired with a TOLED layer, and (b) one in which an electrophoretic display such as E-Ink or E-paper is paired with a TOLED layer. Additional layers can, of course, be added in other embodiments
