Abstract: A switch-mode power supply comprises a D.C. power source (1-13), a transformer with a primary winding (20), first and second switching transistors (22,24) in series with the primary winding, and drive means (30) for generating signals for controlling the switching transistors. On activation of the drive means (30), a diode (44) completes a circuit through the first transistor (22) and part of the primary winding (32) and draws energy from a junction (19A) between two series connected reservoir capacitors (15A,16A). A field is generated in the core of the transformer which is sensed by an auxilliary winding (42) of the transformer which generates a signal. The signal switches on the second switching transistor (24), allowing a circuit to be completed through both switching transistors and the primary winding of the transformer. A rebalance winding (45) is provided to replace energy drawn from junction (19A) to maintain the capacitors in balance.

Abstract: The invention concerns an RF connector for the connection of a radiotelephone (1) to an external antenna, whereby the telephone and correspondingly a device rack (2) connected to the external antenna have two pairs of matching metal plates (1a, 2a, 1b, 2b) that provide a capacitive two-wire connector-inter­face. In order to avoid too large a size and too high an attenuation, a coil (3a, 3b) is connected in series with the pair of plates (1a, 2a; 1b, 2b) constituting each capacitor, the coil and capacitor being dimensioned so that they form a resonant circuit with an attenuation nearly 0 at the employed transmission frequency. A first balancing transformer (4) before the resonant circuit trans­forms the signal into a balanced signal, and a second balancing transformer (5) after the resonant circuit transforms the signal back to an unbalanced signal to be transmitted further on a coaxial cable.
Patent EP-0439182-A2 (EP)
Inventor: BACKMAN KEITH C
IPC: C12Q1/68
Filed: 1991-01-25
Abstract: The present invention involves methods of improving LCR and PCR amplification schemes by modifying at least one probe/primer end so that the probability of the probe/primer contributing to spurious signal development is greatly reduced. Only after specific hybridization of the modified probe/primer with true target, are the modified ends "corrected" in a target dependent fashion to allow participation of the probe/primer in the enzymatic assembly reaction. Specific modifications depend on whether the assembly is done by ligation (as in LCR) or by extension/elongation (as in PCR).

IPC: G11B20/18
Filed: 1982-10-04
Abstract: In a disk type mass storage facility for data processing systems, a disk format which improves handling of defective segments of medium and reduces access time. The format has three layers. A first, physical layer comprises the bytes, sectors and collections of sectors, as well as error detection and correction codes. A second, logical layer is used to address the physical layer and to collect together sectors to form multiplicity of separately addressable spaces, with space having a distinct functional utility. As a third, functional layer the use of data fields in each space is specified. This layer governs the handling of bad blocks if required, and the use of certain format information. At the physical layer, bits are collected into sectors, sectors are collected into tracks, tracks are collected into groups, and groups are collected into cylinders. These are logically, rather than physically, defined collections. A group is set of tracks wherein individual tracks in a group can be selected in the inter-sector rotation time. At the logical layer, the disk is divided into three main areas, each separately addressable. The first main area is broken down into two sub-areas. The first sub-area (12) is available to the host computing system for its use; the second sub-area (14 and 16) is used for replacement of the bad blocks. The second is for format information. The third main area (18) is for diagnostics. Handling of bad blocks is controlled by a hierarchically layered process. A portion of each disk, distributed across the medium, is reserved as spare sectors to replace defective sectors. After a bad sector is replaced, future attempts to access the bad sector are redirected (i.e., revectored) to the replacement sector. For the simplest revectoring, the bad block is replaced by a replacement block in a known location. If that cannot be done, multiple copies of the replacement block's header are stored in the bad block's data field and the copies are compared to find the replacement address. If the comparison fails, or the header cannot be read, a back-up table is available to match the available replacement addresses with the original address which was replaced. A special code is used to identify blocks wherein the medium is good but the contents of the block are logically corrupted.
