Patent number: 11721201Abstract: Transmitting a radio frequency identification (RFID) interrogation signal into an RFID interrogation zone of an Electronic Article Surveillance (EAS) system. Detecting at least one response signal from a first RFID tag of the EAS system responding to the interrogation signal. Capturing, at one or more times in a window of time around the detection, sensor data within a sensor field, the sensor field and the RFID interrogation zone overlapping to form a zone of interest. Characterizing movement of a non-tag object during the window of time based on the captured sensor data. Determining whether the first RFID tag is associated with the characterized non-tag object based on a comparison of the at least one response signal and the characterized movement of the non-tag object.Type: GrantFiled: April 7, 2022Date of Patent: August 8, 2023Assignee: SENSORMATIC ELECTRONICS, LLCInventors: Eric Floyd Riggert, Michael Sansur, Adam S.

Patent number: 11620458Abstract: A radio frequency identification (RFID) system first interrogates, in a first mode, one or more particular target zones of the plurality of target zones including a given target zone. Each particular target zone is interrogated with one of the antennas at a time at a first power for the particular target zone. The RFID system monitors, upon first interrogating, for a trigger condition to occur. In response to the trigger condition not occurring, the RFID system continues the first interrogation in the first mode. In response to the trigger condition occurring, the RFID system second interrogates the given target zone in a second mode at a second power with a plurality of the antennas. The second power for the given target zone is greater in an aggregate across the second interrogating antennas than the first power for the given target zone.Type: GrantFiled: August 4, 2022Date of Patent: April 4, 2023Assignee: Sensormatic Electronics, LLCInventors: Steve Edward Trivelpiece, Adam S. Bergman, Eric Floyd Riggert, Manuel A. Soto

Patent number: 7088803Abstract: A modem utilizing a DAA having line side circuitry including a telephone network interface and system side circuitry including a host system interface. The line side circuitry and the system side circuitry are separated by a high voltage isolation barrier. In accordance with the invention, the high voltage isolation barrier and other DAA circuitry are configured such that data and control information may be communicated between the system side circuitry and the line side circuitry using a serialized digital communication protocol. In one embodiment of the invention, the line side circuitry of the modem includes detection and measurement circuitry that is programmable to measure or establish electrical characteristics (e.g., tip/ring voltage and loop current) of the telephone line interface connection. Command information for the programmable circuitry is multiplexed with data communicated across the high voltage isolation barrier.Type: GrantFiled: November 6, 2003Date of Patent: August 8, 2006Assignee: Silicon Laboratories, Inc.Inventors: Raphael Rahamim, Thomas Grey Beutler, Eric Floyd Riggert

Patent number: 6731749Abstract: A telephone line interface circuit is disclosed having intelligent line current control that can adjust to the various requirements of worldwide telephone systems (DC masks), and/or can reduce the power consumed by the interface circuit. A controller reads a voltage value and based on the theoretical model of a telephone line network, and the expected current/voltage characteristic, as dictated by the appropriate DC mask. The controller sets the line current (via an output voltage) to an optimum value and causes the line voltage to adjust so as to comply with the DC mask and/or minimize power dissipation in the circuit.Type: GrantFiled: May 14, 1999Date of Patent: May 4, 2004Assignee: Conexant Systems, Inc.Inventors: Frank Sacca, Raphael Rahamim, James Bunde Villadsen Skov, Eric Floyd Riggert
