  • Patent number: 11334783
    Abstract: Systems and methods are provided for assembling an RFID device mounted to a fabric substrate via a “flip chip” approach. The system includes a pin thermode with a tip configured to penetrate the fabric substrate. The pin thermode may include or omit a heating element, with the tip being variously configured. The tip may have a variable cross-sectional area or include a plurality of projections that separately penetrate the fabric substrate, for example. If the pin thermode includes a heating element, a body of the pin thermode may be formed of a low thermal conductivity material to allow the temperature of the tip to increase without increasing the temperature of the body to the same degree. The body may define a lumen, with the tip and/or body defining an aperture for flowing a liquid out of the pin thermode and into the region surrounding the pin thermode.

  • Patent number: 11063350
    Abstract: An edge enabled void antenna (EEVA) apparatus is provided. The EEVA apparatus includes a conductive plane and a void is created on a geometric perimeter of the conductive plane to form an EEVA. A radio frequency (RF) port is coupled to the void to receive an RF signal. The RF signal excites the conductive plane to induce an electrical current along the geometric perimeter of the conductive plane. The void can cause the electrical current to increase and decrease on the geometric perimeter of the conductive plane, thus causing an electromagnetic wave corresponding to the RF signal being radiated from the EEVA. By forming the EEVA on the geometric perimeter of the conductive plane, it may be possible to enable a well-functioning antenna apparatus with a small effective footprint, thus allowing multiple EEVAs to be provided in a space confined wireless device with sufficient isolation for improved RF performance.

  • Patent number: 10916029
    Abstract: One aspect of the invention relates to a method of detecting a spatial orientation of a transducer by a handheld optical scanning device. The method comprises steps of providing a first spatial orientation feature on at least a first outer housing surface of the transducer and arranging a handheld optical scanning device in a sightline of the first spatial orientation feature at a selected spatial orientation relative to the first outer surface of the transducer housing. The method comprises further steps of identifying the first spatial orientation feature, detecting a spatial orientation of the handheld scanning device in a predetermined coordinate reference system and determining a spatial orientation of the transducer in the predetermined coordinate reference system.

  • Patent number: 10885287
    Abstract: An article management system includes multiple reader devices that read the RFID tags attached to the articles. Moreover, a central terminal partitions an article management area into multiple middle areas that are in turn partitioned into small areas, and then causes reader devices arranged in two or more small areas to work in a predetermined order for each small area, to read information of the RFID tags. The range of radio wave interference distance assumed for a reader device in a first middle area partially overlaps with a second middle area. Thus, when causing the reader devices arranged in the first middle area to work in order, the central terminal controls a reader device in the second middle area that lies outside the range of radio wave interference distance from a reader device working in the first middle area.

  • Patent number: 10839177
    Abstract: An electromagnetic interposer circuit is attachable to an article that is also equipped with an anti-counterfeit and anti-theft/tracking electromagnetic marker. The interposer circuit includes a first interface for exchanging electrical signals with the marker at a first, shorter, communication range and a second interface coupled to the first interface for exchanging electromagnetic signals with a reader at a second, longer, communication range. The first and second interfaces exchange signals with the marker and the reader, respectively, over a radiofrequency bandwidth that includes a first frequency band and a second frequency band. A filter circuit block within the interposer circuit between the first interface and the second interface operates to block the transfer of signals between the first interface and the second interface over the first frequency band.

  • Patent number: 10763588
    Abstract: A shield, when coupled to a tracker device that is worn by an individual, reduces interfering signals originating from the human body that can adversely impact the detection of signals transmitted by the tracker device. The shield can include multiple layers of components. Specifically, the shield includes a base component that is attached to an adhesive element on the first side of the base and covered by a removable backing. Furthermore, the base, through a second side of the base, is attached to a first non-conductive element, which is further coupled to a second non-conductive element. Each of the non-conductive elements attenuates interfering signals that originate from the human body and therefore, enables the detection of signals transmitted by the patient tracking system. For example, in view of the reduced interference signals, a RF signal transmitted by the patient tracking system can be detected at remote distances.
