Patent number: 8373544Abstract: RFID apparatus includes transmission means for transmitting an RF signal; reception means for receiving a modulated RF signal; and demodulation means for demodulating a received modulated signal. The apparatus comprises generating means for generating a RF signal dependent on an incoming RF signal, the incoming RF signal being generated by different apparatus, and the apparatus is arranged to transmit the generated RF signal such that the generated RF signal interferes with the incoming RF signal. The RFID apparatus has both the means to respond to an RF reader device, in tag emulation mode, and means to function as an RF reader device, in reader mode.Type: GrantFiled: October 29, 2004Date of Patent: February 12, 2013Assignee: Innovision Research & Technology PLCInventor: Glen Pitt-Pladdy

Patent number: 8368514Abstract: An electronic device and a method of operating the device. The device receives a first signal having a first frequency and a predetermined signal strength and retransmits a signal after a latency period and during a time period. The device comprises an oscillation circuit operating in a sub-threshold area in a meta-stable, first mode of operation. When the first signal is received, the oscillation circuit is trigged and passes to an active mode in a second mode of operation, wherein the circuit oscillates. Finally, the device is reset to the first mode of operation. The device may have an identity, which is used for the purpose of the system, which may be an RFID system.Type: GrantFiled: September 3, 2007Date of Patent: February 5, 2013Assignee: LeptonRadio ABInventors: Per-Arne Wiberg, Urban Bilstrup

Patent number: 8362880Abstract: A method and apparatus for loading and executing program code at a micro-processor are disclosed. In this method, a monitoring procedure is performed to monitor whether the micro-processor receives a loading request corresponding to a target program code. If the loading request is received, the target program code is loaded from an external memory into an internal memory of the micro-processor. The micro-processor is then rebooted to enter a first mode in which the target program code in the internal memory is to be executed.Type: GrantFiled: April 27, 2009Date of Patent: January 29, 2013Assignee: MStar Semiconductor, Inc.Inventors: Chih-Hua Huang, Chih Yen Chang

Patent number: 8354918Abstract: A method to elicit a behavior in response to a simplex communication signal comprises receiving, at a receiver device, an encoded simplex communication signal from a transmitter device, the simplex communication signal including an identifier. The method further comprises referencing a stored program in the receiver device to a stored program block corresponding to the identifier. The receiver device then initiates execution of the program block and renders a behavior in accordance with or corresponding to the program block corresponding to the simplex communication signal. The receiver device includes a program database, wherein the receiver is programmed to reference a stored program block of the program database corresponding to the identifier. The receiver device also includes mechanisms to enable a behavior in accordance with the program block to be audibly and visibly perceived.Type: GrantFiled: August 24, 2009Date of Patent: January 15, 2013Inventor: Stephen W. Boyer
