Title: Millimeter wave and far-infrared detector
Inventor: KUTSUWA TAKESHI
IPC: G01R29/08
Filed: 2000-07-07
Abstract: The invention provides a millimeter wave and far-infrared detector of extreme sensitivity and shorter response time. The detector comprises an input (1) for introducing incident millimeter wave or far-infrared radiation (2) to a detector antenna;  a semiconductor substrate (4) on which is formed a single-electron transistor (14) for controlling the current penetrating a semiconductor quantum dot (12); and bow tie antennas (6, 6a, 6b, 6c) for concentrating millimeter wave or far-infrared radiation (2) onto a semiconductor quantum dot that define a submicron space in the single-electron transistor (14). The quantum dot forming a two-dimensional electron system efficiently absorbs the concentrated radiation and maintains the resulting excitation state for more than 10 nanoseconds so that more than 1,000,000 electrons can be transported for a single photon absorbed.
Patent CA-2341803-A1 (CA)
Inventor: BOLLINGER J DANIEL
IPC: A61P25/06
Filed: 2001-03-23
Abstract: A new oral polymeric controlled release formulation suitable for the once-a- day administration of valproate compounds, such as divalproex sodium, has been discovered. This formulation exhibits significant advantages over the sustained release valproate formulations of the prior art. This formulation minimizes the variation between peak and trough plasma levels of valproate over a 24 hour dosing period. This formulation follows a zero-order release pattern thus producing essentially flat plasma levels of valproate, once steady-state levels have been achieved. This results in a significantly lower incidence of side effects for patients consuming such a formulation.

Premièrement, on prépare du NaXO¿2? de structure stratifiée du type .alpha.-NaFeO¿2? en faisant réagir des quantités stoechiométriques d'un sel de sodium ou d'un sel du métal X en solution de manière à former un précipité; on sèche ce précipité et on le soumet à un traitement thermique à une température comprise entre 650 et 720 ·C dans de l'air; et on refroidit rapidement le précipité à température ambiante dans l'air. Ensuite, on soumet le NaXO¿2? à un échange d'ions avec un sel de lithium en solution dans un solvant non alcoolique, à une température comprise entre 140 et 210 ·C. L'oxyde de lithium et de manganèse obtenu peut être utilisé comme matériau de cathode dans une pile au lithium rechargeable.

Abstract: A quilting machine (10) is provided having at least one set of single needle stitch forming elements. The stitch forming elements include a needle (36) and a looper (39) mounted on separate heads (35, 38) that are independently moveable on a bridge (30) transversely relative to the panel. The bridge (30) is longitudinally moved by a servo (32) and the heads (35, 38) are transversely moved on the bridge (30) by separate servos (43, 44). A controller (60) drives the servos to chain stitch patterns and differentially move the heads transversely to account for transverse needle deflection. The drives of the needle and looper are phased to compensate for longitudinal needle deflection. The controller may store empirically determined data and respond to control signals and/or sensors (81, 82) to determine or predict deflection and calculate needle deflection compensation.

Title: Multiple job signals per processing unit in a multiprocessing system
Inventor: EGELAND TERJE
IPC: G06F9/38
Filed: 1999-11-12
Abstract: The invention is directed towards a multiprocessing system (10) having multiple processing units (34A-D). According to the invention, for at least one of the processing units in the multiprocessing system, a first job signa l is assigned to the processing unit for speculative execution of a corresponding first job, and a further job signal is assigned to the processing unit for speculative execution of a corresponding further job. Th e speculative execution of said further job is initiated when the processing unit has completed execution of the first job. If desirable, even more job signals may be assigned to the processing unit for speculative execution. In  this way, multiple job signals are assigned to the processing units (34A-D) of the processing system, and the processing units are allowed to execute a plurality of jobs speculatively while waiting for commit priority. By assigning multiple job signals for speculative execution by one or more processing units, the effects of variations in execution time between jobs a re neutralized, and the overall performance of the processing system is substantially improved.

Title: Method of calculating capacity of intelligent battery, intelligent battery and portable electronic device
Inventor: ODAOHHARA SHIGEFUMI
IPC: G01R31/387
Filed: 2001-10-24
Abstract: To provide a method of calculating capacity of an intelligent battery, the intelligent battery and a portable electronic device capable of allowing for power consumption by a minute current undetectable by a conventional circuit without any special cost required so as to consequently allow an error of capacity data to be smaller. The capacity data in a low electric power consumption mode such as while in a soft-off mode is calculated based on the capacity data acquired by multiplying a consumption electric current value in a low electric power consumption mode acquired in advance by the time that the mode continues and voltage or the capacity data acquired by multiplying the consumption electric power value in the low electric power consumption mode acquired in advance by the time that the mode continues rather than capacity calculation based on the electric current value measured by a current measurement circuit of a battery itself, and so it allows the power consumption in the low electric power consumption mode to be calculated correctly so as to make the error of the acquired capacity data smaller.

Patent CA-2363462-A1 (CA)
Title: Electronic emergency brake load weigh device
Inventor: WOOD JAMES A
IPC: B60T13/66
Filed: 1998-06-08
Abstract: An electronic load weigh device is used with a railcar truck control unit. A  relay valve provides to a brake cylinder a pressure proportional to the pressure impinging upon its control port. A first feedback signal is indicative of the pressure at the control port. A  second feedback signal is indicative of the load borne by the truck. A pressure switch opens when pressure within a trainline changes to a level indicative of an emergency. By controlling the opening and closing of application and release magnet valves, a controller controls the pressure impinging on the control port and thereby service braking of the wheels of the truck. The load weigh device includes (i) circuitry for electronically compensating for the load during braking and (ii) a mechanism for granting the circuitry exclusive control over the magnet valves. Should such emergency occur, the mechanism responds to such emergency by disconnecting the controller from the magnet valves. This gives the circuitry exclusive control over the magnet valves. The circuitry compensates for the load borne by the truck during emergency braking by selectively opening and closing the magnet valves, according to predetermined criteria using the feedback signals, thereby controlling the magnitude of the pressure impinging upon the control port. Absent such emergency, the mechanism responds to such absence by connecting the controller to the magnet valves whereby such service braking on the truck is normally controlled, yet the circuitry is still enabled to compensate for the load during such service braking.
