Inventor: CARRENDER CURTIS LEE
IPC: H04B1/713
Filed: 2002-04-01
Abstract: A radio-frequency identification (RFID) interrogator (23) is provided that generates pseudo-randomly selected radio frequency interrogation signals for transmission on a first antenna (28) and receives the reflected modulated radio-frequency signals via continuous-wave backscatter from a RFID tag device through a second antenna (30) coupled to a heterodyne receiver (31) where data is extracted. The RFID tag device can be configured to write data as well as have data read there from the interrogator. The frequency-hopping transmission in combination with the heterodyne reception provides higher power levels with substantially reduced interference, as well as the ability to link with bounced signals at certain frequencies, increasing the level of communication in the RFID system.

Title: Polyurethane and elastic fiber obtained therefrom
Inventor: MASUI TAKASHI
IPC: C08G18/65
Filed: 2000-04-04
Abstract: A polyurethane which is obtained from ingredients comprising a high-molecula r polyol, an organic polyisocyanate, and a chain extender comprising a specifi c trifunctional isocyanurate compound having an aromatic hydroxyl group and/or a benzylic hydroxyl group, and which has a crosslinked structure due to the isocyanurate compound. The polyurethane has excellent elastic recovery, and the urethane bonds at the crosslinking sites reversibly undergo cleavage and bonding at a certain temperature. From this polyurethane can therefore be produced an elastic fiber which can be thermally set in a high degree at temperatures not lower than a certain temperature and which, after the therm al setting, has the same excellent elastic recovery as the fiber which has not undergone thermal setting.

Abstract: Tickets (10) available in a detection zone (22) are stamped in a first step (marq) with an information unit (ST) transmitted by a transmitter (31). At the beginning of the provision of a service, in a second step (phase1), another first information unit (S<SB>G</SB>) is transmitted and those tickets (10) available in a first frame (CF) in predetermined slots are transmitted with a second information unit (T) whose receipt is confirmed by a second transmitter/receiver (32) by way of a confirmation message Q. Those tickets (10) not assigned to a slot are assigned to a slot in another frame (ACA). In a third step (phase2), second information units (U) are specifically transmitted to the tickets (10) so that the provision of a service can be registered both on the ticket (10) and on the transmitter/receiver (31, 32).
