Title: Linear regulator with zero crossing coordination
Inventor: JACKSON JONATHAN KEITH
IPC: G05F1/571
Filed: 2008-03-28
Abstract: A power regulator comprises a linear regulator HV that regulates a rectified AC signal Vin, to give an output Vs connected to two switches S1, S2. Switch S1 is operated by the difference between the rectified AC voltage and a reference VREF1; and switch S2 operates to provide a current bypass to switch S1 when the difference between voltage VINT at the output of the switches and another reference VREF2 is equal to or greater than a predetermined amount. Switch S1 limits the current flow through the regulator, typically when the unsmoothed rectified AC voltage is high, but the current limit can be overridden by switch S2 when high current is demanded, such as at start-up. Switch S2 can be a zener diode (fig 7, D3), bypassing current when its breakdown voltage is exceeded and reference VREF2 can be derived from the linear regulator output. Switch S1 can be a transistor such as darlington pair (fig 7; Q2,Q3) whose base is connected by a potential divider to the rectified AC input. The regulator can further comprise a smoothing capacitor (fig 7, C2) at the output of the switches a; a full wave rectifier (fig 7, D2) a MOSFET (fig 7, Q1) regulator and a further linear regulator LV (fig 7, Q4) or a buck converter.

Title: Holographic display with viewer eye tracking via microprism array
Inventor: MISSBACH ROBERT
IPC: H04L47/2416
Filed: 2008-05-16
Abstract: A holographic display includes a spatial light modulator (SLM) and a position detection and tracking system, such that a viewers eye positions are tracked, with variable beam deflection to the viewers eye positions being performed using a microprism array which enables controllable deflection of optical beams. Image beam deflection can be continuously variable, and may use electrowetting technology; beam deflection may be controlled by using variable voltage differences applied to different electrodes on an electro wetting cell array. Micro liquid prisms may be used. Two dimensional (2D) beam deflection may be achieved by using two microprism arrays in series, and prisms can have different deflection angles. Also, lens aberrations and phase discontinuities may be corrected dynamically through SLM encoding. An additional SLM may provide phase compensation for the prism array. Various combinations of transmissive and reflective prism arrays and SLMs are disclosed.

Title: Selecting optimal processor performance levels by using processor hardware feedback mechanisms adjusted according to stall count
Inventor: FENGER RUSSELL J
IPC: G06F1/32
Filed: 2008-09-26
Abstract: A system is provided which uses hardware feedback to select optimal processor frequencies and reduce power consumption as part of adaptive power management. An effective P-state is determined in step 101 by comparing the cycle count of current actual processor frequency (APERF) adjusted by a cycle count of processor stall time with the cycle count of the maximum processor frequency available (MPERF). The target P-state is determined in block 103 by multiplying a measure of the percentage of time the processor is busy (%Busy) by the effective P-state. If the target P-state is not the same as the current P-state (step 105) the processor is transitioned to the new P-state in step 107 and the counters (APERF/MPERF) reset. The selection may also include a predetermined acceptable performance loss percentage.

Title: Viscous Lupulin and Method of Forming.
IPC: C12C3/00
Filed: 1969-02-25
Abstract: 1,190,670. Hop extracts. JOHN I. HAAS Inc. Feb.25, 1969 [April 8, 1968], No.10053/69. Heading C6E. A viscous lupulin paste is formed by confining a mass of lupulin glands and rupturing the lupulin glands of the mass to release the encapsulated constituents within the glands. The glands may be ruptured by extrusion through 0À2 mm. apertures (the extrusion process being repeated at least twice), by crushing them between steel rollers adjusted to a clearance of 0À025 mm. or by abrasion for 15 minutes in a blender having cutting blades rotating at such a high velocity that the heat generated serves to liquefy the viscous lupulin paste produced whereby it is rendered flowable (temperatures of at least 140‹ F.). The process of rupturing may take place in an atmosphere of nitrogen or carbon dioxide. When a can of the viscous lupulin paste perforated with several small holes is suspended above, or immersed in, boiling wort, the paste is warmed and rendered flowable, and leaks out of the holes of the can into the boiling wort. The viscosity of the paste is normally within the range 1000-100 centiposes at temperatures between 140‹ and 180‹ F.

Title: Improvements in the supply of air to compression-ignition engines wherein the vacuum in the intake pipe is utilised to operate the brakes
IPC: F02D33/02
Filed: 1946-04-02
Abstract: 617,179. Preventing stalling of engines. ALBION MOTORS, Ltd., and STEAD, E. B. April 2, 1946, No. 10224. [Class 7 (ii)] In an engine for vehicles having vacuumoperated brakes and other accessories, a spring-urged idling valve 1, controlling an orifice 3 on the engine side of the throttle valve 6, closes when the throttle valve closes, setting up the high vacuum necessary to exhaust the vacuum tank through a pipe 9, and opens when the speed drops to admit idling air and avoid stalling of the engine. The valve 1 is so shaped that its position from a stop 4 bears a linear relation to the force due to the pressure difference closing the valve. Thus, if the valve opens when the speed has dropped to a predetermined value, it closes immediately it rises above the speed with the valve 6 still closed. The spring 2 is adjustable by means of locknuts 2a, 2b. Specification 497,878 is referred to.

Title: Improvements relating to electro-magnetic switches
Inventor: VICKERY ERNEST CLEMENTS
IPC: H01H50/54
Filed: 1955-04-13
Abstract: 787,667. Electromagnetic switches. STONE & CO. (DEPTFORD), Ltd., J. April 6, 1956 [April 13, 1955], No. 10653/55. Class 38 (5). A switch intended for use as a cutin switch in a train-lighting installation &c. for automatically connecting a generator to a battery and/or a load at a predetermined generator voltage, comprises shunt and series windings 2, 3 mounted on a yoke 1 and controlling a clapper armature 6 carried on a structure 7 pivoted by a cross leaf spring hinge 9. Arms 10 on the structure 7 operate, respectively, a normally open main contact 11 and a normally closed main contact 12, the contacts being pivoted at 13 and biased by springs 14. An arcing contact 15 carried by the structure 7 and connected in shunt with the contact 11 closes before and opens after the latter contact. A spring 19 connected at one end to a temperature-compensating bimetal 23 and at the other end to an adjustable screw device 24 mounted on an arm 17 of the structure 7, restores the armature. The winding 3 is in series with the contact 11 and the load, the winding 2 being initially energized through contacts 26, 35 of an auxiliary switch which short-circuit an adjustable economy resistance 25. The circuit is given in Fig. 5, not shown. The auxiliary switch comprises a blade 27 connected at its lower end to a pivot pin 33 carried in a mounting 34, the blade being held in a bowed condition by a pair of coil springs 30 connected between eyes 31 in the upper end of the blade and ends of the pin. The contact 26 on the blade is operated with a snapaction between a pair of fixed contacts 35, 36 by a bifurcated finger 28 embracing the blade with lost-motion and fixed to the structure 7. The arrangement produces a large operating differential relative to the position of the armature 6 so that when the coils 2, 3 are energized the blade 27 is not snapped to disengage contact 35 and engage contact 36 until the armature has nearly completed its movement, whereas when the armature releases, the blade 27 is not returned until the armature has nearly engaged its back stop 20.
