Abstract: A new data format used in a communication system employing binary phase shift keying modulation and demodulation is described. The data format provides for a frame comprising a plurality of variable data bits and synchronization bits. The number of variable data bits in the data format of the present invention is more than the number of synchronization bits. The data format preferably includes a CRC field for error detection. In order to uniquely decode the information contained in the frame, the inverse of frame should not be a valid frame. A method for detecting invalid frames is also disclosed.

Abstract: A portal for automatically exciting and reading a passive transponder type tag, which is excited by an inductively coupled signal of a first predetermined frequency and which simultaneously produces a magnetic field and an electrostatic field modulated with a digitally coded identifying signal, while the tag is moving along a substantially horizontal conveyor belt. The portal comprises: a rectangular frame for placement around a portion of a substantially horizontal conveyor belt in a direction transverse to the direction of movement of the conveyor belt; first, second, third and fourth exciter coils, mounted respectively on an upper, a lower and respective side panels forming the walls of the frame, for producing a magnetic field of the first predetermined frequency within the interior of the frame; a curtain formed of a plurality of spaced flexible rectangular flaps of non-conductive material which are suspended from the upper panel within the frame, extend in a direction transverse to the direction of movement of the conveyor belt, and are of a length such that at least one flap will be contacted and deflected by an object moving along the conveyor belt; a pickup coil, serving as a magnetic field receiving antenna, and an electrostatic field receiving antenna disposed in each flap; and a receiver circuit, connected to each of the magnetic pickup coils and the electrostatic field receiving antennas, for detecting a coded signal of the second frequency received by any of the pickup coils and the electrostatic field receiving antennas.

Abstract: A proximity detection system which combines the advantages of an electrostatic (electric) field coupling mechanism with those of an electromagnetic coupling mechanism in order to overcome the disadvantages of the respective individual coupling mechanisms. The system includes a coded tag (9) which is excited with an induction field, i.e., by using an electromagnetic coupling mechanism (13, 17) as has been done in the past in such proximity identification systems, but which transmits stored data back to the receiver (5) using both an electric field coupling mechanism (47, 52) and an electromagnetic field coupling mechanism (50, 53). The receiver (5), in turn, is provided with a novel preamplifier circuit arrangement (55, 73-85), so that it can simultaneously receive signals via either or both of these coupling mechanisms.

Abstract: A transponder for use in an object indentification system including an interrogator which transmits a continuous interrogation signal and detects a responsive identification signal transmitted by the transponder. The transponder receives and detects the interrogation signal and, in response to receipt of the interrogation signal, produces a repeating identification signal having a fixed number of binary bits consisting of an identification data portion of a specified number of consecutive bits less than one half of the fixed number of bits, and a synchronization pattern of consecutive bits consisting of first, second and third bits of alternating binary values, a consecutive sequence of a plurality of bits which are all of the same binary value as the second bit, and a single bit of the same binary value as the first and third bits. The identification signal is modulated onto a carrier signal and transmitted. Preferably, the first, second and third bits and the sequence of a plurality of bits constitute one half of the fixed number of binary bits of the identification signal, with the binary value of the first bit being a binary 1.
