Abstract: An electrical signal jitter and wander measurement system (30) operates in real time and digitally controls bandwidths over which the measurements are performed. A digital phase-lock loop ("PLL") (34) includes a phase detector (44), low pass filters (48, 56), an analog-to-digital converter ("ADC") (54), a digital signal processor ("DSP") (32), a direct digital synthesizer ("DDS") (38), and a tracking oscillator (39). The phase detector receives an input signal that is compared with a signal derived from the DDS. The phase detector signal contains wander and jitter data that are filtered and digitized by the ADC. The DSP receives the data and performs a proportional integral control function to lock the PLL by digitally controlling the DDS frequency. The DDS generates a clock signal at a precise rate determined by the phase accumulation registers. The tracking oscillator locks to multiples of the DDS frequency to increase the resolution of the phase measurement.

Abstract: In a method for automatically identifying an unknown number of transponders, these transponders are put into a dead state by a collision signal transmitted by the reader. Then, each transponder generates its own random dead time and the transponder with the shortest dead time is the first to transmit its data to the reader, while the other transponders are put into an idle state. When the reader has completely received the data of the first transponder, the idle states of the other transponders end and they generate another dead time for themselves. The entire process is then repeated, i.e., the transponder with the shortest dead time transmits its data to the reader, etc. until all transponders have transmitted their data to the reader individually and successively.

Abstract: A display device, in form of a panel meter which includes a combination of a linear bar graph and digital numeric display, linearly displays a non-linear input variable at an infinite number of input points. A microprocessor receives a digital input, which can be a converted analog signal, representing a non-linear variable such as a liquid level height in a tank or reservoir or a corresponding analog input received through an analog to digital (A/D) converter. A non-volatile memory stores a finite set of predetermined number n of correlated input/output points (x.sub.n, y.sub.n ) which together define a conversion function for converting a given input (x.sub.n) at any given point (x.sub.n, y.sub.n ) to an associated output (y.sub.n). Each two adjacent points (x.sub.0, y.sub.0) and (x.sub.1, y.sub.1) define a straight line segment. The microprocessor is programmed to interpolate for any given input x between two points (x.sub.0, x.sub.1) to provide an output (y) between associated outputs (y.sub.0, y.sub.

Abstract: This invention of a proportional force modulation wheel slide protection process for steel wheel/steel rail vehicles. It applies particularly to self-propelled transit type railway vehicles. It uses a slide detection logic which predicts the force reduction needed to control slippage and correct the slide condition. The force modulation is made on the basis of the initial prediction and the time that a slide has been in effect to determine if greater force reduction is needed to effect a slide correction. Sensing of positive to negative axle rate polarity shift is used to determine when a slide has been corrected and normal braking force can be restored. This process is used to control slides by modulating both the dynamic and friction braking in like manner. The normal braking control devices are used to reduce braking force during slide correction. Although this process could be implemented through the use of discrete circuits, it lends itself to microprocessor applications.

Abstract: In a data bus with m data bits, electromagnetic interference is produced by polarity switching the data on that data bus. When two consecutive data items result in a change of over half of the data bits, the polarity of the second data item is switched, and a polarity signal is correspondingly switched on the data bus. When the data is received, it is restored to its original polarity by adjusting the polarity of the received data according to the signal on the polarity line. In this way, the total number of bit transitions between any two data items is reduced to a maximum of m/2.

Abstract: In advanced digital networks for providing selective point-to-point communications between subscribers terminals and broadband server equipment operated by a plurality of independent information service providers, routing through the network is controlled by functionality identified as a Level 1 Gateway. The Level 1 Gateway will perform a variety of functions including communications port management of transmissions of information between subscribers and servers, processing of billing information and session management. The Level 1 Gateway generates menus of providers, either as a function of providers available through a particular portion of the network or in a customized fashion specified by individual subscribes. The Level 1 Gateway may also provide a PIN number functionality, e.g. to permit parents to limit which providers their children can access.
