Abstract: Radio-Frequency identification (RFID) locationing systems and methods for locating one or more items positioned within a defined space are disclosed herein. An example embodiment includes energizing, by an RFID reader having an RFID antenna, an RFID tag corresponding to an item positioned within a defined space. Each of a first signal strength and a second signal strength of the RFID tag is detected, respectively, by a first RFID receiver node of a first node channel and a second RFID receiver node of a second node channel. A controller alternates a multiplexor to receive at the multiplexor each of first signal strength data from the first RFID receiver node and second signal strength data from the second RFID receiver node. The first signal strength data and the second signal strength data is provided to the RFID reader and combined to determine a location of the item positioned within the defined space.

Abstract: At least some embodiments of the present invention are directed to RFID reader systems configured to estimate a directional bearing of an RFID tag. In an embodiment, the present invention is an RFID system configured in a way that upon a detection of a variance in the direction of a maximum RSSI value for a given RFID tag in response to a plurality of interrogation signals transmitted by an RFID reader over a respective plurality of different directions, the RFID reader retransmits the plurality of interrogation signals over the respective plurality of different directions with successively lower power levels until the only response(s) being received no longer exhibit the previously detected variance.

Abstract: A dual-mode data capture system includes a capture controller, a point cloud generator, a collision detector, a plurality of cameras viewing a capture volume, and a motion sensor to generate a detection signal when an object arrives at a capture position within the volume. The controller: activates a subset of cameras in a collision detection mode to capture sequences of images of the volume; responsive to receiving the detection signal, activates the cameras in a dimensioning mode to capture a synchronous set of images of the capture position. The collision detector: determines whether the sequences of images indicate a potential collision; and responsive to detection of a potential collision, generates a warning. The point cloud generator: receives the synchronous set of images and generates a point cloud representing the object based on the synchronous set of images, for use in determining dimensions of the object.

Abstract: The disclosure is an antenna device, comprising a substrate layer and a patch antenna assembly on the substrate layer, configured to contain at least one patch antenna element. Each patch antenna element has a feed insertion cutout and a base cutout, where a feed line extending from a feed point on the substrate layer couples to the antenna element in the feed insertion cutout. Each patch antenna element corresponds to a respective parasitic patch element, positioned above the patch antenna element, and a respective capacitive loading element, positioned on the feed line and proximate to the patch antenna element, to improve the performance of the antenna device. Each parasitic pat antenna is larger than its respective patch antenna element. The antenna device may also include a mounting structure to position each parasitic patch element over each patch antenna element.

Abstract: Imaging devices, systems, and methods for determining a distance to an object using light projected from an illumination device are provided. An example method includes: projecting, from an illumination source of the illumination device, projected light having a first wavelength; receiving, at one or more sensors of the illumination device, reflected light having the first wavelength; receiving, at the one or more sensors of the illumination device, emitted light having a second wavelength; determining, by one or more processors, a phase difference between the reflected light and the emitted light; and determining, by the one or more processors, the distance to the object based at least on the phase difference between the reflected light and the emitted light.
