Abstract: The present disclosure relates to a mobile agent in an RFID system with reduced power consumption and increased localization capabilities. In one aspect, a relay circuit attached to a mobility mechanism such as a drone or robot is in communication with an RFID reader and a backend host computer. The mobile agent moves around a warehouse, for instance, in which landmark RFID tags are arranged. The mobile agent can transmit with an adjustable power to identify a single landmark tag and associate it with object tags of one or more objects within the range of the mobile agent. The host computer can communicate with the mobile agent to instruct it to adjust its power when multiple landmark tags are detected.

Abstract: An example wearable device includes a haptic actuator to produce a haptic vibration in response to a target input waveform, a haptic effect sensor to measure a haptic vibration corresponding to the haptic vibration and to output a measured haptic vibration waveform and a feedback circuit to modify the target input waveform to reduce a difference between the haptic vibration and a measured haptic vibration waveform.
