摘要： An apparatus and method for forming a RAM data memory that generates predictable noise/interference components that are coherent with each write cycle and essentially independent of the data content of the RAM data memory. The RAM data memory is comprised of a plurality of cells, each representing a data bit, which are selectively addressable as memory bytes formed of multiple bits. Each cell is formed of two sets of cross-coupled transistors. By causing each set of cross-coupled transistors to be set to a common voltage level at the beginning of a write cycle before setting one set of transistors to a low level and the one set of transistors to be set to a high level (thus representing a desired data bit value), the associated noise/interference components of the power drain are data independent. Furthermore, the data-independent noise occurs at frequencies at or above the write cycle rate.

摘要： A transponder system including a transponder and an interrogator having a transmission coil for producing a high-intensity electromagnetic field for inductively powering the transponder and two receiver coils for receiving a low-intensity electromagnetic field reradiated by the transponder. The transmission coil includes one or more conductive windings circumscribing a substantially polygonal volume of space. The receiver coils are diametrically disposed opposite one another within the volume space of the transmitter and are electrically connected to each other in a differential circuit relationship, the output of which is at a minimum when the two receiver coils receive approximately equal quantities of energy and is at a maximum when one of the receiver coils receives more electromagnetic energy from the transponder than the other receiver coil. The transponder uses a coil to derive both a power source and a clock pulse from the high-intensity field for powering and driving an identification circuit. The frequency of the clock pulse is then divided by 8 to drive the memory array and logic network of the identification circuit so that it clocks out a new data bit every 16 cycles of the carrier frequency. The output of the memory array is then used to phase modulate a subcarrier, which is at 1/2 the frequency of the carrier frequency. The subcarrier frequency of 1/2 the carrier frequency is chosen to maximize the amplitude of the transmitted subcarrier. The transponder also includes a double pulse lockout circuit which prevents rapid consecutive short-outs of the transponder's coil.

摘要： A coil assembly for use in an inductively powered transponder including a primary coil and a secondary coil wrapped around the same coil forming ferrite rod. The primary coil's leads are left floating while the secondary coil's leads are connected to the integrated identification circuit of the transponder. There are approximately three times as many turns to the primary coil as there are turns to the secondary coil. The primary coil is configured to self resonate at the operating frequency of the identification circuit when brought within range of an interrogator's magnetic field, thereby creating a voltage across the primary coil having a high source impedance. The secondary coil is configured to resonate at the same operating frequency, but to convert the high source impedance level of the primary coil to a low source impedance level, which is more suitable for powering the identification circuit and which substantially matches the impedance level of the secondary coil to the impedance level of the interrogator field, thereby maximizing the quantity of energy which can be transferred between the interrogator and the transponder.

摘要： An electromagnetic transmission and detection apparatus comprising a transmission coil (20) for producing a high intensity electromagnetic field including one or more conductive windings (24) circumscribing a substantially polygonal volume of space having a central axis, and first and second receiver coils (22) disposed within the polygonal volume of space for receiving a low-intensity electromagnetic field transmitted from an external source. The receiver coils (22) are co-planar with the transmitter coil (20) and are disposed within the polygonal volume of the transmitter coil at positions which are polygonally, diametrical opposed to one another. The receiver coils (22) are electrically connected to each other in a differential circuit relationship such that the magnitude of electrical signals induced in the receiver coils (22) by uniform electromagnetic energy are substantially equal and opposite to one another. The differential circuit is operative to substract the electrical signals induced in the receiver coils and output a differential output signal, which is at a minimum when the two receiver coils receive approximately equal quantities of energy and is at a maximum when one of the receiver coils receives more electromagnetic energy from the external source than the other receiver coil. A display device (19) receives the differential output signal and displays a measure of the identification signal when the differential output signal is at a maximum.

摘要： A compressor comprises a variable gain path and a feedback path. The variable gain path includes a modulator which, in response to an input signal and a feedback signal, outputs a train of pulses whose widths and heights are modulated. Also in the variable gain path, a demodulator converts the pulse train into a compressor output. Feedback is derived from the variable gain path.
