Title: Method and apparatus for displaying multi-frequency bio-impedance
Inventor: WITHERS PAUL OWEN
IPC: A61B5/05
Filed: 1992-04-27
Granted: 2001-11-06
Abstract: A method and apparatus for displaying complex impedance and related physical characteristics of an object (30) at a plu-rality of sinusoidal frequencies over a wide frequency range. Excitation signal waveforms (10, 14, 18) are stored in digital form. Digital sampling and processing circuitry (84, 86) provide high form. Digital sampling and processing circuitry (84, 86) provide high noise immunity and accurate measurement at all impedance phase angles.  The technique is particularly well-suited to the measurement of complex impedances in living biological tissue because the digital implementation results in highly accurate mea-surement values over a plurality of selectable frequencies within a wide sinusoidal frequency region. A novel adaptation of digital cross-correlation (84) and convolution (86) techniques is used to simultaneously display (72) real and imaginary electrical imped-ance of living biological tissue at several selectable sinusoidal frequencies.

Granted: 1999-07-20
Abstract: The apparatus comprises a light source, generally a laser diode,  providing a beam that is modulated by an input signal and is controlled for scanning,  at a rate fixed by a clock, along a generatrix line of a photosensitive drum which is rotated by a motor: it further includes a  memory for storing input data representing successive pixels of all  lines in a page which were scanned  for transmission, and a computer for determining the length to be reproduced of the transmitted document, and for determining the width, necessary to avoid truncating the information contained in any of the scan lines, in the width direction.  The computer calculates the minimum vertical reduction ratio Rv and the minimum horizontal reduction ratio Rh that should be adopted in order to enable the useful information to be reproduced in length and width and selects the smaller ratios. The frequency of the clock and the motor of the drum are controlled to achieve the smaller reduction ratio both in the horizontal direction and in the vertical direction.

Patent CA-2129103-C (CA)
Inventor: CIRCEO LOUIS J JR
IPC: E02D3/11
Filed: 1993-01-25
Granted: 2001-11-20
Abstract: A method and apparatus for in-situ solidifying and stabiliz-ing a mass of unstable foundation soil (A, B) utilizes a plasma arc torch (30). The torch is inserted into a drilled and cased hole (22) to a selected depth in a subterranean unstable soil layer and the torch is energized. The intense heat generated by the torch melts the soil material close to the hole and forms a pool of melt (26) while more remote sections (28, 29) are baked to a brick-like con-sistency or dried and strengthened. Upon cooling, the central melt-ed soil material cools to a hard, vitrified column (24) with physical properties equivalent to a hard, dense rock. Variations of the meth-od apply to a variety of construction support problems and land-slide remediation problems.

Title: Apparatus for dithering
Inventor: FORTIN JEAN
IPC: H04N5/349
Filed: 1995-03-13
Granted: 2004-11-23
Abstract: An dithering system for implementation of a microscan that dithers an image on an array of sensing elements that defines an image plane by moving one or more lenses which displaces the image focused on the image plane. Piezoelectric positioners are provided to move the one or more lenses a predetermined amount and on a predetermined plane parallel to the image plane so that the image focused by the lensing system on the array of sensing elements is displaced on the image plane by the movement of the lensing system. As the lens is moved by the positioners and thus the optical axis of the lens, the image passing through the lens is also moved on the image plane. Moving the lens horizontally and vertically or in a predetermined pattern provides dithering of the image so that microscanning can be employed.

Granted: 2001-02-06
Abstract: The control system controls the operation of a charge coupled device. The operation of the charge coupled device is responsive to a shift clock signal of a given frequency and a shift enable signal. The control system includes a timer for generating one of a number of shift clock signals. Each of the shift clock signals has a different frequency. A programmable register stores a plurality of control bits which may be programmed into the program memory of the control system. A multiplex switching is used for selecting one of the shift clock signals in response to the state of the control bits and directing the selected shift clock signal to the charge coupled device. An address decoder in response to addressing by the microprocessor, generates the shift enable signal which signal is directed to the charge coupled device concurrently with the presence of the selected shift clock signal.

Granted: 1999-04-13
Abstract: In a fuel supply system for a multi-cylinder engine, a pump driving cam is provided between an intake cam and an exhaust cam on a camshaft.  The pump driving cam and a fuel pump are interconnected by a pump driving member.  The pump driving member is slidably supported on a pair of supporting portion projectingly,  integrally provided on a cylinder head and disposed between valve springs of a pair of intake valves.  Thus, the intake valves and the valve springs are prevented from interfering with the pump driving member and the supporting portions and therefore, the fuel pump driven by the camshaft in the multi-cylinder engine can be disposed at a lengthwise intermediate portion of the cam shaft. As a result, the distance between the fuel pump and each of carburetors can be decreased to enable a stable supplying of fuel.

Title: Object-oriented programming environment that provides object encapsulation via encryption
Inventor: VOLDAL ERIK EDWARD
IPC: G06F12/14
Filed: 1997-02-05
Granted: 2004-10-19
Abstract: This invention relates in general to object-oriented encapsulated enforcement mechanisms. In particular, a hardware independent object encapsulation enforcement mechanism is disclosed herein. The object encapsulation enforcement mechanism of the present invention uses encryption technology to ensure that data controlled by an object is accessed solely through use of the object's method programs. When an object is instantiated, the virtual address used to refer to the object is encrypted before it is returned to the instantiating application program. When access to a previously instantiated object is requested, the object encapsulation enforcement mechanism decrypts the presented object address and passes the address to the identified method program, thereby ensuring that only object method programs have access to data controlled by the object.
