Patent EP-0419029-A2 (EP)
Inventor: CORCORAN JOHN W
IPC: H04B10/118
Filed: 1990-08-10
Abstract: A multi-channel rotary optical coupler (30) incorporates a multi-­element lens assembly (35) formed of a coplanar plurality of annular lens elements (35a,35b,35c,35d), with each lens element of the assembly having a substantially constant annular width and a discrete optical axis, with each optical axis of each lens element (36a,36b,36c,36d) displaced about a central rotational axis of the coupler. Each lens element receives an output from a respective light source and provides discrete data channels for the continuous transmission of discrete data signals through the lens elements to respective similarly radially displaced optical detectors (4a,4b,4c,4d) of a detector array (40).

Abstract: The present invention provides a straightforward sensor and method for quench detection in a superconduct­ing coil (1), magnet or inductor. The superconducting sensor of the present invention consists of a probe (4) having a twisted loop of superconducting wires (5, 6) in a protective sheath (7) which is co-wound with the supercon­ducting coil (1), and a readout device (8). A very small amount of energy is applied to the superconducting loop of wire in the probe by the readout device (8) and its resistance is monitored by readout device. When joule heating occurs in the superconducting coil (1) as a result of a portion becoming normal, the heat is transferred to a corresponding portion of the probe (4) causing a portion of the superconducting wires (5, 6) therein to become normal. This causes the resistance in the superconducting wires to change and this change is detected or measured by the readout device (8) which is magnetically coupled to the wires (5, 6) of the probe (4).

Abstract: An electronic watthour meter is digitally configurable to operate as several different types of watthour meters for metering electrical energy from a variety of different electric utility services Automatic scaling of line input currents is provided to scale the voltage input to an analog to digital converter over selected ranges such that low level and high level input signals are measured in an optimum range. A digital signal processor is employed to calculate values for metered electrical energy and output pulses, each proportional to a guantum of energy flowing in the circuit being metered The processor calculates the value of DC offset errors inherent in the various analog circuits of the meter and uses that value in the calculation of metered electrical energy to compensate for such offset errors The meter employs automatic and manually initiated test functions for testing the operation of the processor and other critical circuits in the meter

Abstract: According to the temporary address system in the radio communications system of the present invention, as a temporary address data, an identification number determined based on the number of repeated zones in which the pattern of the same frequency is repeated, is assigned to a radio base station (P), and a temporary identification number, which is valid temporarily in the area of the base station is assigned to a terminal device (T). Real address data, which corresponds to said temporary address data, and is used to specify a terminal device, is stored in a not-yet-used transmission data field during traffic of control data, which is conducted for setting up a radio link between a base station (P) and a terminal device (T), and is transmitted. Thus, in the radio communication system, using an address field having a limited number of bits, more number of terminal devices (T) than that is possible with the bit length, can be used in the area of a base station (P).

Abstract: The network is interactive (return of information to the server). It operates in two frequency ranges distinct in transmission and in reception. These two frequency ranges are divided into sub-ranges and there is a head-end modem for each sub-range. A user modem comprises a first oscillator (1) whose frequency is equal to the difference between the reception frequency (FR) and the frequency desired as intermediate frequency (FI), and a second oscillator (4) provided with a frequency slaving circuit (11). A mixer (5) mixes the signals from the two oscillators, then the signal passes through a frequency divider (2) and is brought to the slaving circuit (11). After passing through a divider (3), the signal from the second oscillator provides the transmission signal (FE). <IMAGE>

Abstract: Apparatus and methods for time multiplexing a resource among a plurality of entities at average rates and with deterministic delays between accesses to the resource by an entity. An entity accessing the resource received a time slot on the resource; a fixed number of time slots constitute a frame. Each entry receives a fixed allocation of time slots in the frame. When an entity has work for the resource to do, it receives access to the resource for a number of slots in each frame equal to the lesser of the number of slots required to do the work and the number of slots in the allocation. A rate-controlled server is disclosed which defines a frame and allocations therein, as well as a hierarchy of servers which combines rate-controlled traffic with best traffic. In the hierarchy, a rate-controlled server activates a round-robin server when the entitles served by the rate-controlled server do not require all the slots in a frame. A hierarchy of rate-controlled servers is further disclosed which permits access to the resource at widely-differing average rates. In that hierarchy, a number of slots in the frame for a given member of the hierarchy are reserved for the next number down of the hierarchy and the next member down is active only during those slots. Further disclosed are nodes of ISDN networks employing ATM which incorporate the servers and hierarchies thereof.
