Patent number: 11763650Abstract: Managing foreign RFID tags within a secured area involves use of a first RFID portal system to read tag data from an RFID tag present within a first portal zone. A processing device associated with the first RFID portal system is used to determine whether the RFID tag is entering the secured area. The determination is based on an evaluation of a direction of travel of the RFID tag through the first portal zone. Responsive to determining that the RFID tag is in fact entering the secured area, one or more operations are performed to cause a first tag value corresponding to the tag data to be added into a safe to exit (STE) list.Type: GrantFiled: July 10, 2020Date of Patent: September 19, 2023Assignee: Tyco Fire & Security GmbHInventors: John C. Y. Huang, Tamlyn J. Jones, Eric F. Riggert, Steven J. Raynesford, Glen Ouellette, Steve E. Trivelpiece

Patent number: 11514768Abstract: Systems and methods for operating an EAS detection system. The methods comprise: detecting an Active Security Tag (“AST”) in an EAS detection zone; determining whether AST is coupled to an object identified in a list; and performing operations when a determination is made that AST is coupled to a listed object. The operations involve: accessing sensor data generated by at least one sensor device disposed on/near display equipment associated with the listed object; processing the sensor data to determine whether a person was within a defined distance range of AST during a period of time immediately preceding the detecting; concluding that a false alarm scenario exists when the sensor data indicates that a person was not within the defined distance range of AST during the period of time; and suppressing alarm issuance by the EAS detection system in response to the false alarm scenario conclusion.Type: GrantFiled: November 9, 2020Date of Patent: November 29, 2022Assignee: SENSORMATIC ELECTRONICS, LLCInventors: Glen Ouellette, John C. Y. Huang, Steve E. Trivelpiece, Ian Westmacott

Patent number: 4720839Abstract: Partial response and quadrature partial response data transmission system characterized by increased transmission rate, lower signal-to-noise ratio, low cost and simpler hardware implementation than prior art systems. A steep filter (almost rectangular) is connected to the output of a cosine filter, forming a composite filter, wherein the cut-off frequency of the rectangular filter is less than the Nyquist frequency by a predetermined amount which is inversely proportional to the amount in percentage by which the data transmission rate exceeds the Nyquist rate. The system is thus capable of signalling at the Nyquist rate and greater, without requiring that channel filter parameters or the basic clock rate be adjusted. A smaller number of signal levels can be selected (as compared to previously existing methods) for spectrally efficient applications, and the resulting more robust system can also be used to transmit PAM, QAM, and other baseband or modulated signals.Type: GrantFiled: December 2, 1986Date of Patent: January 19, 1988Assignee: University of OttawaInventors: Kamilo Feher, Kuang-Tsan Wu, John C.
