Title: System and method for selective regression testing
Inventor: CHEN YIH-FARN ROBIN
IPC: G06F9/06
Filed: 1995-04-13
Abstract: A system and method for selective regression testing of a software system that determines which test units of a test suite must be re-run after a modification to the software system. The entities which are covered by each test unit are identified. When the software system is modified the entities which were changed by the modification are identified. The test units which need to be re-run are determined by analyzing the change information and the coverage information to select those test units that cover changed entities.

Title: Optical glucose sensor
Inventor: SLATE JOHN B
IPC: A61B5/00
Filed: 1995-06-28
Abstract: An improved glucose sensor adapted for in vivo implantation includes one or more optical fiber optrodes mounted within a semipermeable probe housing designed  for  differential  diffusion  of  glucose  and oxygen.    In  a  preferred  form,  an  enzyme  optrode comprises  an  optical  fiber  with  an  enzyme coating such as glucose oxidase for catalyzing glucose in the presence of  oxygen  (O2)  to  produce  gluconic  acid and hydrogen peroxide.   An oxygen sensitive coating such as a fluorescent dye is provided on the enzyme optrode in  close  proximity  with  the  enzymatic reaction,  and  also  on  a  reference  optrode  at  a position  spaced  substantially  from  the  enzymatic reaction.    Optical  monitoring  of  the  fluorescent activity   of  the   optrode  coatings  provides   an indication  of oxygen depletion  as a result of the enzymatic reaction,  and thus also indicates glucose concentration  level.   The  semipermeable housing  is designed to ensure that the reaction proceeds with a stoichiometric excess of oxygen (O2).

Filed: 1995-02-01
Abstract: Bâtonnet extrudé (10) pour friandises et procédé de fabrication. Ce bâtonnet (10) est formé au moyen d'un procédé d'extrusion de façon à inclure une pluralité de rainures encastrées (20), ce qui réduit la quantité de matériau utilisé ainsi que le poids du bâtonnet tout en conservant sa rigidité structurale. Une partie dégagée (65) peut être prévue dans les rainures afin d'empêcher que les bâtonnets placés les uns au-dessus des autres ne se bloquent réciproquement. L'utilisation d'un procédé d'extrusion assure une fabrication plus simple et plus économique, tout en permettant une plus grande souplesse dans la conception du profil du bâtonnet.

Title: Optical method of measuring an alternating electrical current, including temperature compensation, and a device for carrying out the method
Inventor: BOSSELMANN THOMAS
IPC: G01R15/24
Filed: 1994-03-10
Abstract: In a magneto-optic method of measuring an a.c. current in a conductor, the plane of rotation of linearly polarized light is rotated through a measuring angle in a Faraday element surrounding the conductor, the angle being a measure of the current strength. This light is divided into two linearly polarized light signals, with polarization planes directed at right angles to each other, which are converted by opto-electro converters into corresponding electrical signals.      The two signals are used to form a functional value that represents the temperature. This value is used, together with the first signal, to determine a temperature-compensated measuring signal for the a.c. current.

Title: Non-Active Regenerative Systems
Inventor: MARGOLIS DONALD L
IPC: B60G17/015
Filed: 1994-12-21
Abstract: A non-active regenerative system (20) which regenerates energy by taking energy from relative motion of members (22) and (24) and using it later to accomplish overall improved performance and eliminates the need for an active source to provide assisting forces. The non-active regenerative system (20) includes an energy transformer element (26) interconnecting a first member (22) and a second member (24) which converts relative motion to an energy in storable form, and an energy management element (30) which channels the flow of energy to and from an energy storage element (32) to produce assisting forces. The energy management element (30) is commanded by a controller (36) which is responsive to sensors (34a, 34b, 34c, and 34d) which provide signals indicative of the system condition. Power is supplied to the energy management (30), sensors (34a, 34b, 34c, and 34d), and controller (36), only if required, by power source (40). However, no active power source is needed to drive the transformer element (26).

Title: Method of obtaining diagnostic reagents, assays and therapeutics based on clinical manifestations of a disease
Inventor: SANTI DANIEL V
IPC: G01N33/68
Filed: 1994-11-17
Abstract: Antibodies are recovered and isolated from the sera of a number "n" of patients each of which have or have had the same given disease so that each of the "n" patients has, within a large number of different antibodies, some antibodies uniquely associated with the same disease of interest.  The antibodies of a first patient are bound to a support surface. To carry out initial screening libraries of molecules, such as peptides displayed on the surface of bacteriophage, are brought into contact with the bound antibodies of the first patient under conditions where binding will occur.  Unbound molecules (peptides) are washed away and bound molecules (peptides) on the bacteriophage are identified.  Secondary screening is then carried out by extracting and labeling the antibodies of a second patient and using the labeled antibodies to probe the molecules (peptides) isolated in the initial screening.

Title: Image detection system
Inventor: DONELLY ROSS ALEXANDER
IPC: G06T7/00
Filed: 1996-05-21
Abstract: An image detection system is disclosed for the detection of all image in an input pixel stream. An image is input as a input pixel stream (19) and accumulated and converted (112,113,114) into cells which are formed into cell data portions from regions of a corresponding image of the input pixel stream (19). A template storage ROM (15) stores at least one template that comprises a multiplicity of cell data entries derived from an desired image to be detected. A comparator matrix (115) is connected to the cell converter (112,113,114) and the template ROM (15) for comparing the cell data portions with a multiplicity of cell data entries to derive a template detection signal (215) when a predetermined number of the cell data portions match with the multiplicity of said cell data entries. The system finds particular use in the prevention of fraudulent copying of images, such as bank noted using colour laser copiers and printers.

Abstract: A method and apparatus for providing a three-way connection between a mobile computing device, a stationary computing device and a computer network. When there is an established connection between a mobile computing device (e.g. a notebook computer) and the stationary computing device (e.g. desktop PC) over the wireless communication channel (e.g. infrared link), the system operates in BRIDGE mode. In BRIDGE mode the system redirects information packets in the OSI layer 2 (data link layer). When a notebook computer is not attached, the system operates in PASSTHROUGH mode and all non-broadcast message traffic from the Ethernet LAN is filtered by the Ethernet adapter based on the network address or group address of the desktop PC.

Inventor: KHOURY GEORGE
IPC: H03F1/32
Filed: 1996-06-19
Abstract: A tree mixer includes a first differential pair of transistors which divide current from a first current source between the transistors in dependence upon a first differential input signal supplied to first input terminals. Two second differential pairs of transistors have controlled paths which conduct current, divided between the transistors of the differential pair in dependence upon a second differential input signal supplied to second input terminals, dependent upon current passed by a respective transistor of the first pair of transistors, to produce a product signal at output terminals. One or more second current sources provide for the total current passed by the first pair of transistors to be greater than the total current passed by the two second pairs of transistors, for improved linearity without increasing noise. A quadrature phase modulator can include two such mixers with common output circuitry.

Title: Device and treatment machine for the mechanical treatment of high-consistency fibrous material
Inventor: SCHNELL HANS
IPC: B01F23/57
Filed: 1996-11-08
Abstract: Treatment tools for the mechanical treatment of high-consistency fibrous material, and preferably for dispersing waste paper. The treatment tools are provided with teeth and are moved past one another with tight spacing so that the fibrous material disposed between treatment tool may be subjected to high shearing forces. Because of the intense loading of the teeth, the teeth may be arranged together in groups.
