Publication number: 20240104317Abstract: A reader includes a first antenna, a second antenna spaced apart from the first antenna, an RFID reader circuit, and a processor. The first antenna and the second antenna are connected to the RFID reader circuit. The first antenna is configured to receive a first signal from an RFID tag. The second antenna is configured to receive a second signal from the RFID tag. The processor controls the RFID reader circuit to determine a first value of a signal parameter associated with the RFID tag based on the first signal and a second value of the signal parameter associated with the RFID tag based on the second signal, receives, from the RFID reader circuit, the first value and the second value, and determines, based on the first value and the second value, whether the RFID tag is located between the first antenna and the second antenna.Type: ApplicationFiled: December 7, 2023Publication date: March 28, 2024Inventors: Hong Zhu, Gary Ellerbusch

Patent number: 6195414Abstract: Apparatus (100) and accompanying methods for accurately simulating a digital facility, including impairments, in a public switched telephone network (PSTN). The invention is particularly suited for precisely emulating, as part of that facility, a line card within a channel bank including a hardware coder-decoder (CODEC) circuit contained therein, but without using an actual CODEC. Specifically, to properly emulate a digital facility, including such a line card, impairments, which need to be emulated, arise not only from the network facility itself but also from the line card. The former include robbed bit signaling (RBS), digital trunk loss and network delay. The latter include intermodulation distortion (IMD), analog loss and echo. To achieve very precise emulation, the simulator implements IMD and network impairments digitally but with the former impairment being processed at much higher, i.e., oversampled, (illustratively 32 kHz) sample rate relative to the sample rate for the latter impairments (e.g.Type: GrantFiled: April 11, 1998Date of Patent: February 27, 2001Assignee: Telecom Analysis SystemsInventors: Charles W.
