IPC: H04B7/26
Filed: 1995-03-06
Abstract: A portable security system is based on maintaining wireless communication between two or more plastic cards within a defined range. In the simplest form, a first card intermittently transmits an identification code to a second card. The second card compares that code with a code in an internal register, and on matching those codes, transmits a return code to the first card. The first card compares the return code with a code in an internal register, and on matching those codes, resets a timer. If the timer is not reset during a defined number of transmissions by the first card, an alarm circuit is activated. One card is attached to a valuable object such as a wallet on the person, and the other card is placed elsewhere on the person; theft of the object from the person results in activation of the alarm circuit. In an advanced form, a master card communi-cates with a series of slave cards; each of the slave cards is attached to a different valuable object on the person.

Title: Dynamic atm network access control using an availability parameter at each port in a network path
Inventor: WONG ALBERT KAI-SUN
IPC: H04Q3/00
Filed: 1995-06-15
Abstract: A facility is provided in an ATM network to control the level of data traffic that a source of data supplies to the network for transmission over an associated connection. Such control is achieved by associating a scout cell with an availability parameter (Ac) and also associating each output port serving a segment of a connection with an availability parameter (Ap) indicative of the level of congestion at the port.  Responsive to receipt of a scout cell, an output port overwrites the availability parameter (Ac) contained in the scout cell with its availability parameter (Ap) only if the latter value is less than the former value.  The output port then forwards the scout cell to its intended destination.  The destination port performs the same function, and then returns the scout cell to its originator via the reverse direction of the connection.  Accordingly, the value of the availability parameter Ac contained in a returned scout cell thus indicates whether or not congestion exists at a point along the forward direction of a connection. That is, the value of Ac will be a minimum of all of the port availability parameters (Ap1, Ap2, .... Apn) values that the cell encountered as it traversed the associated connection. The level of such control is then determined as a function of the value of the availability parameter contained in the received scout cell.

Title: Fractional bit-leaking clock signal resynchronizer for a high-speed digital communications system
Inventor: BROWN CARLTON D
IPC: H04J3/07
Filed: 1995-10-13
Abstract: A method and apparatus us are provided for smoothing jitter in a smoothed clock output by routing a portion of the incoming clock signal representing phase hit information through a digital high-pass filter (12), which produces complementary output digital signals . One of the output signals includes the higher order bits of the filtered phase hit signal, and the other output signal includes the lower order bits of the filtered phase hit signal. The filtered, complementary phase hit signals are summed with the stream of clock pulses to be smoothed. Each of these summed signals is supplied to a separate phase detector circuit (120, 121). The phase detector (120) receiving the higher order bit signal generates a coarse error signal, and the phase detector (121) receiving the lower order bit signal generates a fine error signal. These fractional coarse and fine error signals are summed and converted to a high resolution analog control signal which drives a voltage controlled oscillator (50) in a phase-locked loop circuit. The phase-locked loop functions as a type two, second order low-pass filter and generates the smoothed clock output signal. An elastic buffer (18) is used to time-coordinate the incoming data signals and the smoothed clock signals output from the resynchronizer circuit (100). The phase hit adjustments are thus low-pass filtered by the phase-locked loop, which is controlled by the high resolution analog signal. Consequently, the effects of these phase adjustments on the smoothed clock output signal are introduced slowly and more evenly over a relatively longer period of time, which significantly reduces jitter as compared to existing techniques.

Title: Transmission bit rate discrimination method and apparatus
Inventor: TAKAKI TETSUYA
IPC: H04B1/7075
Filed: 1995-11-02
Abstract: The invention provides a transmission bit rate discrimination method and apparatus wherein, when a base station in a mobile communication which makes use of spectrum spreading performs transmission at a variable bit rate using four different transmission bit rates and repetitively transmits transmission symbols of a low transmission bit rate, a mobile station detects a rate of repetitions of received symbols and discriminates the transmission bit rate of received data simply.  A received symbol sequence for one frame is inputted to shifters for shifting the received symbol sequence by one, three and seven symbol distances, respectively, and a correlation calculator for calculating an auto-correlation.  The outputs of the shifters are inputted to correlation calculators for calculating cross-correlations, and results of the correlation calculations are inputted to a comparator, by which they are compared with reference to a result of the auto-correlation calculation to discriminate the transmission bit rate.  A switch is switched in response to the discriminated transmission bit rate so that the received symbol sequence is sent out to one of Viterbi decoders which corresponds to the transmission bit rate.
