Title: Audio/power jack for ic card
Inventor: BETHURUM GARY CAIN
IPC: H01R24/58
Filed: 1997-02-13
Granted: 2000-07-04
Abstract: The rear of a thin IC card is provided with a jack (42A, 42B, Fig. 4) that can receive a multi-contact audio type plug (40) having a diameter that is more than half the thickness of the card. The circuit board has a slot (60) that opens into the rear of the card. A U-shaped insulative block (80) is mounted on the card, with the opposite arms of the block lying at opposite sides of the board slot. Sheet metal contacts are mounted on the block and project into the slot in the circuit board, with each contact having a vertically-extending plug-engaging part (120) lying in the circuit board slot. The IC card includes a housing with a rear end cap (140) having a largely cylindrical passage (142A, 142B) that guides an audio-type plug into the slot in the circuit board to engage the contacts thereat. The end cap is constructed to form a rearward extension of the card that projects rearward of a card-receiving host slot, to enable a wide plug handle to be inserted against the rear of the end cap.

Abstract: A method for analysing an integrated circuit (IC). At least a portion of a layer of the IC is scanned using high magnification to obtain images of the IC. The images are registered to create a mosaicked image. An IC layout database is created in the form of a set of polygons from the mosaicked image, where the step of creating the IC layout database is performed after, or pipelined with, the registering step. The process is repeated for plural IC  layers, as necessary. Polygon sets from each layer are vertically registered into alignment with minimal distortion. A netlist or schematic diagram is generated to represent the scanned IC portion based on the registered set(s) of polygons.

Title: Orthomolecular medical use of l-citrulline for vasoprotection, relaxative smooth muscle tone and cell protection
Inventor: WAUGH WILLIAM HOWARD
IPC: A61K33/12

Granted: 2002-05-07
Abstract: This invention is a novel method in orthomolecular health to sustain favorable amounts of L-arginine efficiently within the human body for preservation of good health and amelioration of various disease states. The method provides administration of sizable amounts of L-citrulline as precursor substance for bioconversion to L-arginine in order to maintain greater blood plasma concentrations of L-arginine as potential substrate for various metabolic functions. The method is useful to increase the availability of substrate for nitric oxide production by constitutive nitric oxide synthases. Embodiments include uses of exogenous L-citrulline for more vasoprotection in sickle cell disease and atherosclerosis, more stability in circulating platelets, more relaxative smooth muscle tone during pregnancy and in achalasia, greater defense against angiostenosis after angioplasty, greater defense against oxidative stress, enhanced cell stores of creatine, enhanced fertility in males with oligospermia, and greater defense against osteoporosis.

Title: A stripe pattern matching system
Inventor: HOSHINO YUKIO
IPC: G06T7/00
Filed: 1998-02-26
Granted: 2001-04-10
Abstract: To provide a stripe pattern  system enabling to verify minutia correspondence between a searching stripe pattern and a filed stripe pattern independent of position or direction of the searching strip pattern, correspondence value between them is evaluated by comparing their distances, directions or relations to their each neighboring minutiae by a pairing examination means (16). The most appropriate rotation angle and the most appropriate shifting coordinates for adjusting the searching stripe pattern to the filed stripe pattern is obtained by selecting a most appropriate axial candidate giving the most concentrated coordinate deviations referring to deviation distributions of correspondence values accumulated on a deviation plane memory (18) by applying each axial candidate as the coordinate adjustment reference. Therefore, the most appropriate coordinate adjustment can be performed even when either or both of absolute direction and position cannot be specified, in the invention.

Abstract: A Hall effect plasma accelerator comprises an annular accelerating channel with a radial magnetic field applied across the channel between magnetic poles of opposite polarity. According to the invention, the magnetic poles are defined on bodies of material which are physically and magnetically separate. The accelerator may be used as a Hall effect thruster, producing a stream of ions deflected by appropriate adjustment of the magnetic fields, so as to produce thrust and steer a satellite or other vehicle. The channel, along which the ions are accelerated, is preferably flared outwardly at its open end to avoid erosion caused by the deflection. The adjustment of the magnetic fields is preferably achieved by dividing an outer magnetic pole, surrounding the channel, into separate sectors having individual coils. The invention allows greater freedom in selecting the dimensions of the thruster in general and of the magnetic system in particular, thereby improving thruster efficiency and allowing manufacture of thrusters having a wide variety of different shapes depending on the available space.
