One disclosed example provides a method including compiling and storing on the computing device a list of positioning signals each associated with a geographic location, detecting one or more currently available positioning signals, comparing the one or more currently available positioning signals to the list of positioning signals, and if one or more currently available positioning signals matches one or more matching positioning signals stored in the list, then determining the current geographic location based upon the one or more matching stored positioning signals.

The invention proposes a transmitter (such as a gateway or base station, both indoors and outdoors) that actively creates multiple virtual anchors which are associated with certain known reflectors by means of a code, to allow low-capability receivers to be localized more easily. By measuring propagation features, such as, e.g., timing of receipt, of three or more coded beams, low capability receiverseven those with only a single antennacan be localized, e.g., by the transmitter or by the receivers themselves. The receivers might localize themselves if each beam includes e.g. the location of the anchors, the location of transmitter, and the sending time. This has the advantage that the receivers do not have to send any information back to the transmitter.

An autonomous vehicle for use with an autonomous delivery service that facilitates a service delivery includes: a beacon receiver configured to receive a wireless homing beacon transmitted from a beacon device as a radio frequency (RF) signal that designates a desired delivery location at a service address selected by a subscriber, wherein the wireless homing beacon is modulated by beacon data that identifies the subscriber and includes a pseudo random code sequence generated by a code generator that is recognized by the autonomous vehicle to authenticate the delivery; and wherein the wireless homing beacon is received by the beacon receiver to facilitate the service delivery to the subscriber by the autonomous vehicle at the desired delivery location at the service address selected by the subscriber; an image capture device configured to generate delivery image data captured after the service delivery; and a transmitter configured to transmit the delivery image data captured after the service delivery.

Head-mounted augmented reality (AR) devices can track pose of a wearer's head to provide a three-dimensional virtual representation of objects in the wearer's environment. An electromagnetic (EM) tracking system can track head or body pose. A handheld user input device can include an EM emitter that generates an EM field, and the head-mounted AR device can include an EM sensor that senses the EM field. EM information from the sensor can be analyzed to determine location and/or orientation of the sensor and thereby the wearer's pose. The EM emitter and sensor may utilize time division multiplexing (TDM) or dynamic frequency tuning to operate at multiple frequencies. Voltage gain control may be implemented in the transmitter, rather than the sensor, allowing smaller and lighter weight sensor designs. The EM sensor can implement noise cancellation to reduce the level of EM interference generated by nearby audio speakers.
