ULTRA-WIDE BAND (UWB) RADIO-BASED OBJECT SENSING
First Claim
1. An apparatus for sensing an object, comprising:
- a layer of material; and
a plurality of ultra-wideband, UWB, radio sensors integrated within the layer of material at various locations, wherein individual UWB radio sensors are to;
receive first signals, which are UWB radio signals transmitted from a device attached to an object within a sensing distance of the layer of material, andtransmit second signals based on receipt of the first signals, wherein the second signals are used to determine by another device a location of the object relative to the layer of material.

Abstract
The present disclosure describes a number of embodiments related to devices, systems, and methods locating a an object using ultra-wide band (UWB) radio transceivers embedded in carpet or other flexible material that may be rolled up and moved to various locations. Once in a location, the carpet may be unrolled and the multiple embedded radio transceivers may receive a signal from a tag attached to the object sending UWB radio signals. Based on the signals received by the UWB radio transceivers, various processes including time-difference on arrival, time-of-flight, and phase shift may be used to determine the location or the movement of the object.
