Title: Measuring mis-match between signals
IPC: G10L15/00
Filed: 1981-09-16
Granted: 1983-11-16
Abstract: The degree of mis-match which would be obtained between a test and a reference signal, for example speech signals, should their time-axes be subjected to that relative shift and/or distortion which is required to minimize the degree of mismatch is carried out by sampling the two signals at regular intervals and storing these samples in memories. All the samples of one signal are then read out in succession from one memory; each successive sample of the other signal is read out from the other memory, and the difference between each pair of samples is formed in a subtractor. Each difference value from the subtractor is added to the smallest of three quantities, X, Y and Z and the result stored in a register to form the new quantity X. This new quantity X is also stored in a further memory cyclically addressed in tandem with the memory 12. The quantity Z is the previous content of the location of memory into which the new quantity X is written, and the quantity Y is the previous value of the quantity Z, obtained by shifting the previous value of the quantity Z in a two-stage shift register. Thus the quantities X, Y and Z correspond to the present sample of the other signal and the immediately preceding sample of the one signal, the immediately preceding sample of both signals, and the present sample of the one signal and the immediately preceding sample of the other signal respectively. The result is that each successive value of the quantity X is the optimum cumulative distance value between the two signals for the corresponding pair of samples should these be assigned to each other when matching the two signals to each other. The process is continued until all the sampled value have been read and paired, at which point the value of the quantity X is a measure of the above-defined degree of mis-match.

Title: Cellular telecommunications networks and methods
Inventor: TARGETT DAVID JOHN
IPC: H04W16/32
Filed: 1991-03-22
Granted: 1995-02-15
Abstract: A macrocellular cellular telephone system has cells (macrocells) CI and CII. All the cells CI broadcast a particular Location Area Identity (LAI), and all the cells CII broadcast a different LAI. Upon receipt of an LAI, a macrocellular mobile station (MS) responds and the network thus knows its whereabouts. Communication is thus established with that MS by broadcasting from all cells within the appropriate area I or II. The network is also capable of offering a more restricted service to subscribers to a microcellular system - for example, service in large cities or towns identified at A,B and C. Microcells in these areas transmit LAI's which differ from the LAI's transmitted by the cells available for macrocellular subscribers. By means (for example) of its lower power level, a microcellular subscriber MS can be distinguished from a macrocellular MS and can be denied service unless it is within an area A,B or C. <IMAGE>

Title: A key oriented automatic closing system
Inventor: EMANUELE MOLTISANTI
IPC: E05B/
Filed: 1989-01-16
Granted: 1992-09-09
Abstract: This invention refers to an automatic closing system that uses a key that consists of: a cylinder with radial sockets and cylindrical plugs. These are contained in a casing that allows it only to rotate. It can be used on a door or any other type of compatible support that uses of a switch, a latch or an equivalent device. The key has a disk for the socket connected to a cylindrical tube with a detachable cone-shaped point. The cylinder is made of two or more interchangeable cylinder modules, with radial sockets and is united coaxially with a tightening components. The sockets of the cylinder and their seating are at the end next to the dowel pins. A stepped constriction is used in order to block the thrust of the spring on the pins. In the key tube two or more rings are inserted that are plugged-in, interchangeable and that move together. Each of the ring correspond to only one of the cylindrical modules and in an arranged order occupy the same position. The external surface of the rings present varying depths in their radial cone shaped notches, each of which correspond to only one pin. The cylinder is also made up of a cylindrical head that has a series of radial notches followed by a guide that is formed by two symmetrical blades that end in a slot. The cylindrical button has a cone shaped internal cavity to stop the course of the key inside the cylindrical plug. On the key tube a ring with a small tooth is also provided, plugged-into the last of the other rings. Together they turn onto the other rings. The rotation is generated from the contact of the small tooth with the guide to the symmetrical blades at the end of the insertion phase of the key in the plug. It is interrupted by the presence of the tooth in the slot when the cone-shaped notches of the rings are in position. This unblocks the cylinder from being stopped by the pin. Two blades to block two of the radial notches are provided to stop the cylindrical rotation.

Abstract: A single resource in the form of a data bus (BS) is shared among a number of users in the form of Modules (M). Control of the bus is restricted to not more than one module at a time. Each module is assigned a different n-digit binary identity number, all the identity numbers containing the same number m of ones, and associated with BS there are n lines AB which perform the wired-OR function. When a request for the control of BS is made, the module or modules determines whether the resulting number carried by AB contains exactly m, or more than m, ones. If it contains more than m ones, indicating two or more requestors, arbitration between them takes place in a known manner to determine which of them shall control BS first. But if the number on AB contains exactly m ones there can be only one requestor and so arbitration is disposed-with.
