Patent EP-0356191-A2 (EP)
Inventor: FREEDMAN BARRY ALLEN
IPC: G06Q10/00
Filed: 1989-08-21
Abstract: A method and apparatus is described for optimally allocating resources. The optimal allocation is done by minimizing a cost (which is a convex non-linear function of various allocation variables) subject to different constraints (which are linear functions of the allocation variables). The method initially picks a state of the above variables  (x₀)  in the interior of the solution polytope (where the constraints are satisfied) and computes successive states  x₁,x₂ ,···, which progressively reduces the cost of allocation. The above iteration stops when suitable stopping rules are met. 
     The method employs (i) an affine scaling transformation (a variant of Karmarkar's projective transformation) of the linear constraints, (ii) an ellipsoid to sphere transformation of the curved cost surfaces, (iii) a potential search scheme on the curved constant cost surfaces, (iv) an affine scale adjustment mechanism, and (v) a line-search scheme.

Abstract: A fluorescence polarization immunoassay (FPIA) for detecting the presence of one or more amphetamine-class analytes in a test sample is provided. The immunoassay uses competition between the analyte and a fluorescently labeled tracer for the binding site on an antibody specific for phenethylamine derivatives. The concentration of amphetamine-class analyte in the sample determines the amount of tracer that binds to the antibody. The amount of tracer/antibody complex formed can be quantitatively measured and is inversely proportional to the quantity of analyte in the test sample. The invention relates to tracers, to immunogens used to elicit antibodies for use as assay reagents, and to assay kits incorporating these tracers and assay reagents.

Abstract: Fast logic circuit technology has the disadvantage of generating high power dissipation. In each integrated circuit, however, there are also switching elements which do not participate in the fast switching processes. The power loss of these switching elements is reduced by replacing the load resistors with bipolar transistors and by replacing the fast bipolar switching transistors with MOS switching transistors. It is provided, for example, to use one MOS transistor (T3) as current source, two MOS switching transistors (T1, T2), which are connected at their source terminals, as current switches and two pnp bipolar transistors (T4, T5) as load resistors.

Abstract: For a laser (2) capable of continuous wave operation, a power supply (4) for supplying pulsed power to the laser includes circuitry (76, 78) for modulating the power supplied to the laser in order to generate a pulsed laser output beam. The pulsed operating mode reduces the amount of heat generated during system operation, so that the system may be cooled by an internal. self-contained coolant flow loop. An independent safety monitoring system (46, 54) is capable of terminating tbe laser output in response to any unsafe failure of the control system. An argon laser tube (2) capable of generating between 6 and 7 kilowatts of heat at full continuous wave power generates only 2.5 kilowatts of average power during the electronically pulsed operating mode. A power supply control board (76) controlled by microprocessor based control electronics (6) and the safety monitor (54) controls a tube pulse starter (82) and a power MOSFET pass bank (78) connected in series with the laser tube (2).

A stamper substrate (16) is then applied to force the agent to fill the space between the stamper substrate and the principal surface of the master disk. The stamper-forming photopolymer is cured with UV rays to form an information recording layer on the principal surface of the stamper substrate. The stamper substrate (ii) is stripped from the master disk together with the stamper information recording layer to form a resin stamper, which is then fixed. The stamper information recording surface of the resin stamper is supplied with a liquid replica-forming photopolymer that is UV curable and is strippable from the stamper information recording surface. A transparent replica substrate is then applied to force the photopolymer to fill the space between the replica substrate and the principal surface of the stamper information recording surface. The photopolymer is cured with UV rays, whereby a replica information recording layer of the cured replica-forming photopolymer is formed on the principal surface of the replica substrate. Finally, the replica substrate is stripped from the resin stamper together with the replica information recording layer.

Abstract: 5 n7 A device for storing and delivering a sensor through a catheter. A sensor delivery device (10, 10') includes an elongate tube (20), which is attached to a rigid housing (22, 22'). A sensor (12), stored within a sterile environment comprising an interior of the sensor delivery device, has an attached signal line (16) that extends along the longitudinal axis of the delivery device and through its proximal end. The proximal end is open when the sensor is in its stored position. An eversible sheath (34) extends between the rigid housing and the signal line, sealingly separating the sterile environment (48) in which the sensor is stored from the open end of the rigid housing. To use the sensor, the signal line is moved into the rigid housing, causing the eversible sheath to turn inside out as the sensor is advanced through the catheter into its use position. The protection afforded by the eversible sheath permits the sensor to be withdrawn through the catheter and then reinserted without introducing contamination. A probe stop (54) abuts an inner surface of a catheter fitting (17), precisely controlling the distance that the sensor extends beyond a distal end of the catheter.

Abstract: In a powertrain including an engine (10) controlled by the position of the throttle valve (26), a hydrodynamic torque converter (14) and multiple ratio automatic transmission (18) connected to the drive wheels of the vehicle (22), a solenoid-operated hydraulic valve (38) supplies pressurized fluid to engage and release the clutch (84 resp.86) that controls torque transfer between an offgoing clutch and an oncoming clutch. The position of the throttle valve (TAP) and the speed of the engine (N e ) are applied as input to a mathematical model (60) programmed in algorithmic form for execution by a digital microprocessor. The engine produces a signal representing net torque output by the engine (T e ,) and torque converter (T t ), which signal is applied as input to an inverse mathematical model (62) of the solenoid-operated valve (38) that supplies hydraulic fluid to the controlling clutch. The unique relationship of phase to gain, the frequency response of the solenoid valve (38), is inverted within the frequency range of interest to remove the effects of delay. Torque converter turbine speed error (e) is determined as it is applied as input to a PID compensated feedback control (46), whose output is summed (56) with the inverse of the solenoid valve frequency response to produce a duty cycle supplied to the solenoid that controls pressure in the transmission friction element.

Abstract: Vision correcting lenses utilizing the principles of both Fresnel lenses and Fresnel zone plates are disclosed. The lenses of the present invention provide multifocal vision correction, and are most preferably used to provide intraocular lenses for small incision surgeries. Using the concept of a "tuned" Fresnel lens, intraocular and other types of vision correcting lenses are provided by the present invention which overcome the limitations found in typical Fresnel lenses by phase synchronizing the light passing through the lens. As disclosed, the groove width and depth of the lens may be varied to provide the synchronization, and also to provide multifocal vision. Also, the design of the present invention permits a relatively thin lens to be designed, therefore making it particularly applicable to small incision surgeries since it may be rolled or folded into a configuration which is easily inserted into an incision in the eye.
