Patent GB-1296829-A (GB)
IPC: H03F3/19
Filed: 1968-12-20
Abstract: 1296829 Amplifiers; remote control of TV receivers COMMUNICATIONS PATENTS Ltd 18 Dec 1969 [20 Dec 1968] 60576/68 Headings H3Q and H3T An h.f. amplifier 1, 2 has one end of a coaxial cable 6 connected across at least part of a resonant circuit 3, 4, 5, the other end of the cable 6 connected to an adjustable impedance 8 and the length of the cable 6 is different from a quarter wavelength or any multiple thereof at the resonant frequency of the resonant circuit 3, 4, 5. The amplifier may be an i.f. amplifier for a colour T.V. receiving colour signals on 625 line standard. If resistor 8 is adjusted so that the impedance of resistors 7 and 8 is greater than the characteristic impedance of the cable 6 then a capacitive reactance occurs across capacitor 5 which lowers the resonant frequency of the resonant circuit 3, 4, 5 and modifies the pass band of the amplifier so as to accentuate the signals towards the lower frequency part of the pass band. Conversely if the value of the resistor 8 is reduced an inductive reactance occurs across capacitor 5 and the resonant frequency is raised so as to accentuate signals towards the higher frequency part of the pass band. The resistor 8 may be remotely positioned from the amplifier 1, 2 by the cable 6 so as to enable adjustment of the amplitude of the brightness and colour subcarriers.

Title: Radio frequency responsive targets a method for making same and systems for automatic radio frequency identification of items by such targets
IPC: G01S/
Filed: 1992-09-23
Abstract: A radio frequency automatic identification system detects targets which include solid resonators resonating at several frequencies, attributing information to the frequencies at which the target resonates. Preferred resonators are quartz crystals, which according to the invention, may be made by a process of heating quartz to soften it and cutting crystals to approximate size and resonant frequency. Resonators produced by such a process may be measured to determine their actual resonant frequency, and preferably the crystals may be sorted into predetermined frequency windows in accordance with their measured resonant frequency. A set of resonators having frequencies corresponding to predetermined data can be selected from the sorted groups of resonators and incorporated into a target. A preferred target is an ink-like material having a plurality of resonators disposed in a matrix which is radio frequency transparent at the frequency of interest. Targets maybe detected by repetitively sweeping the frequency of the interrogating signal through a range which includes the information-bearing range of the system. <IMAGE>
