Abstract: In some implementations, a monitoring device associated with a lanyard device may detect that a portion of a strap of the lanyard device has extended from a strap core of the lanyard device. The monitoring device may generate a notification that the portion of the strap has extended from the strap core, wherein the lanyard device is configured to anchor the user to a support structure via the strap, and wherein a sensor within the monitoring device is configured to monitor a position of the strap relative to the strap core. The monitoring device may transmit, to a management device, the notification that the portion of the strap has extended from the strap core, wherein the notification includes an identifier associated with the lanyard device to alert the management device of a hazardous event involving the user.

Abstract: Methods and systems for using barcodes to determine item dimensions are disclosed herein. An example method includes a scanner identifying a barcode in an image of an object, and determining a datum associated with the barcode. A physical feature of the object located outside of the barcode is identified. A comparison of the datum associated with the barcode to the physical feature is made; and, in response, at least one dimension of the object is determined.

Abstract: A server includes: a memory storing calibration data; and a processor connected with the memory, the processor configured to: obtain a point cloud depicting a capture volume containing a transporter having a body and a holder carrying an object to be dimensioned; obtain a set of positions associated with the transporter; based on the set of positions and the calibration data: generate side cutting planes corresponding to sides of the body of the transporter; generate a front cutting plane corresponding to a forward surface of a mast of the holder; and discard points between the side cutting planes and the front cutting plane to obtain a first portion of the point cloud; based on the calibration data, select a second portion of the point cloud from the first portion, excluding a base of the holder; and dimension the object based on the second portion of the point cloud.

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 radio frequency (RF) identification (RFID) reader calibration system for use with a venue includes an RFID reader having a primary identifier and a plurality of secondary identifiers. The primary identifier and each of the plurality of secondary identifiers having a respective unobstructed line of sight to a point on the floor of the venue. The RFID reader calibration system also includes a data capture device configured to be aimed at the primary identifier and the plurality of secondary identifiers and to capture respective coordinates of the primary identifier and each of the plurality of secondary identifiers. The RFID reader calibration system also includes a controller configured to determine: a location of the RFID reader based on the coordinates of the primary identifier; and an orientation of the RFID reader based on the respective coordinates of the primary identifier and each of the plurality of secondary identifiers.
