IPC: H01S3/00
Filed: 1990-08-02
Abstract: Light input means (11) inputs exciting pulsed light beams to a parametric oscillator (12) simultaneously in a plurality of directions. The parametric oscillator (12) including a parametric element (20) such as a urea crystal produces parametric pulsed beams having different wavelengths (ν₁,ν₂). The parametric pulsed beams are corrected into coaxial beams by a correcting optical means (16) which includes an optical fiber (16B), and then group dispersion of the coaxial beams are compensated for by a group dispersion compensating means (18) which may include opposed diffraction gratings (18A-18D). By converting a pulsed light beam using a parametric oscillator (12) and then subsequently applying this to the correcting optical means (16) and the group dispersion compensating means (18) its pulse length is shortened in an efficient manner.

Title: Disk format for secondary storage system
Inventor: RUBINSON BARRY L
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 subarea (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.

Abstract: The present method is an integration of aspects of representation which are sensitive to network prediction and, at the same time, control the architectural resources of the network. In consequence, cell division networks can be used for dynamically and opportunistically controlling the network complexity and thus indirectly its learning efficiency and its capacity for generalisation. Cell division networks are defined with the aid of local noise injections and noise-associated learning rules. As the learning progresses, the cell division network measures the prediction history of particular nodes and can opportunistically split the node if it is considered to be inadequate and, as a result, enhance the resources of the network. <IMAGE>

Abstract: A cardioverting/defibrillating pacemaker with the ability to sense and respond to haemodynamic compromise. The ventricular pressure (VP) and electrical activity of the heart are sensed via one or more transvenous or epicardial devices. The filtered peak-to-peak amplitude (VFPPA) or a peak pressure function (VPPF) based upon the right and/or left VP waveform(s) are derived. In one embodiment the VP and the electrical activity of the heart are sensed and processed continuously, and the VFPPA or the VPPF continuously derived. The VFPPA or the VPPF, and the ECG are used to initiate bradycardia pacing, antitachycardia pacing and cardioversion/defibrillation therapies. In another embodiment the VP and electrical activity of the heart are continuously sensed. The electrical activity is processed continuously and used to determine whether or not some irregularity exists. If so, one of the VPPF or VFPPA is derived and used to decide which of the therapies are to be used. One of the VPPF or VFPPA is also periodically determined to ensure optimal haemodynamic function. In both embodiments the degree of haemodynamic compromise is determined by comparing the derived VFPPA or VPPF with programmed values. An algorithm maximizes the effectiveness of support pacing. Preferably an ECG transvenous sensor in the right atrium and a combined ECG/VP sensor in the right ventricle are used.

Abstract: Clock signals (68-71) synthesized by a first phase-locked loop circuit (60) are monitored by a second phase-locked loop circuit (87). The second phase-locked loop circuit (87) additionally provides clock signal synthesis redundancy and monitors the functional status of the first, signal synthesizing phase-locked loop circuit (60). One (71) or more of the primary clock signals (68-71) are supplied to an input selector (85) which selects and divides, if necessary, one of its input clock signals (33,34,71) and supplies a predetermined frequency signal (86) to the second phase-locked loop circuit (87), the output signal (89) of which is divided (90) to produce a redundant set of clock signals (91-94), one (94) of which is used as a comparison frequency in the second phase-locked loop circuit (87). If the second phase-locked loop circuit (87) detects an out-of-lock (72') condition it supplies a signal (88) to a microcontroller (56) that controls the selection of input clock signals (33,34,71,94) to input selectors (85,55) of the second and first phase-locked loop circuits (87,60) and the selection of clock signal sets (68-71,91-94) by an output selector (75). The circuitry may be used in a telephone communication system (Fig. 1).

Abstract: This invention provides a process to convert linear alkenes such as butene-1 and butene-2 to methyl branched chain alkenes such as isobutylene using one dimensional, medium pore zeolite catalysts and similar type catalysts such as SAPO's and MeAPOS's. The pore size for the catalyst should be greater than 0.42 nm and less than 0.7 nm, preferably with a larger dimension of between 0.5 and 0.6 nm. This pore size allows the branched chain alkenes to form and diffuse out of the catalyst while reducing the formation of unwanted by-products, including dimers, trimers, aromatics and coke. This invention has been demonstrated with H-ferrierite, SAPO-11, and magnesium mordenite in a laboratory scale reactor. Selectivities ranging from about 50% to almost 100% were demonstrated for isobutylene formation using H-ferrierite, at temperatures ranging from about 340°C to about 440°C.
