Title: Circuit Tester
Inventor: SEHDEV ARUN
IPC: G01R27/18
Filed: 2001-10-02
Abstract: A method of making a measurement of line-earth impedance of a three-wire mains circuit which includes a residual current device such as an earth-leakage circuit breaker, which method comprises the steps of: <SL> <LI>(a) measuring the voltage across the line-neutral circuit and the neutral-earth circuit in an unloaded state; <LI>(b) connecting a suitable known load resistance across the line-neutral circuit, so as to cause a relatively high test current to flow, repeating both measurements for the loaded state and calculating the value of the test current from the value of the load resistances and the measured voltages; <LI>(c) dividing the difference voltages by the test current to give the resistances of the line-neutral loop (R LN ) and the neutral lead (R N ); <LI>(d) injecting a low DC current into the neutral-earth circuit and measuring the voltage change to determine the neutral-earth loop resistance (R NE ); and <LI>(e) determining the line-earth loop resistance R LE  from the sum of the live lead resistance (R L ) and the earth lead resistance (R E ) by calculating: </SL> <BR> <BR> R L  = R LN  - R N'; <BR> <BR> R E  = R NE  - R N ; and<BR> R LE  = R L  + R E .<BR> <BR> Several measurements may be arranged in successive half cycles and statistically analysed to minimise the effects of electrical noise or drift. An instrument to perform the above method is also claimed.

Title: User identity verification system
Inventor: POWERS DAVID
IPC: G06F21/34
Filed: 2002-04-11
Abstract: The method is suitable for use in a system comprising a client terminal (10) coupled to a server (20) by a first communication medium (50). A user (1) supplies first identification information to the client terminal (10). The supplied first identification information is transmitted over the first communication medium (50) from the client terminal (10) to the server (20). The server verifies that the first identification information corresponds to a stored user profile and then sends a second identification information to the user over a second communication medium (60, 40) such as a GSM network (60) to the user (e.g. to a mobile phone). The user supplies the second identification information to the server (20) via the client terminal (10) and the user's identity is verified at the server according to presentation of the second identification information. The communication media need not be different. The first information may be contained on a token (e.g. card or CD/DVD) or may be memorised or both. The second information may be used as first information in future identification procedures.

Title: Four-tap demodulation pixel
Inventor: SEITZ PETER
IPC: G01J9/00
Filed: 2002-06-20
Abstract: A two-dimensional, temporally modulated electromagnetic wavefield, preferably in the ultraviolet, visible or infrared spectral range, can be locally detected and demodulated with one or more sensing elements. Each sensing element consists of a resistive, transparent electrode on top of an insulated layer that is produced over a semiconducting substrate whose surface is electrically kept in depletion. The electrode is connected with two or more contacts to a number of clock voltages that are operated synchronously with the frequency of the modulated wavefield. In the electrode and in the semiconducting substrate lateral electric fields are created that separate and transport photogenerated charge pairs in the semiconductor to respective diffusions close to the contacts. By repetitively storing and accumulating photocharges in the diffusions, electrical signals are generated that are subsequently read out for the determination of local phase shift, amplitude and offset of the modulated wavefield. preferred embodiments of the demodulation device comprise four electrode contacts C1, C2, C3 and C4 on the electrode E and corresponding storage diffusions D1, D2, D3 and D4.

Title: Method and apparatus for DNA sequencing
Inventor: IZMAILOV ALEXANDRE M
IPC: C12Q1/68
Filed: 2001-04-12
Abstract: The sequence of a target DNA molecule is determined by preparing four chain termination reaction mixtures, one for each base type. The first set of fragments, indicative of the positions of a first type of base, are labeled with a first fluorescent label. The second set of fragments, indicative of the positions of a second type of base, are labeled with a second fluorescent label different from the first fluorescent label. The third set of fragments, indicative of the positions of a third type of base, are labeled with a third fluorescent label, different from the first and second fluorescent labels or with at least two labels, including at least one fluorescent label selected from among the first, second and third fluorescent labels. The fourth set of fragments, indicative of the positions of a fourth type of base, are labeled differently from the third set of chain-termination fragments and with at least two different species of labels including at least one fluorescent label selected from among the first, second and third fluorescent labels. Thus, a total of only three fluorescent labels are required to label the DNA sequencing fragments. The first, second, third and fourth sets of chain-termination fragments are loaded onto the same lane of an electrophoresis separation medium and separated in an electric field. The separated fragments are detected in real-time as they migrate in the electrophoresis separation medium by irradiating the separated fragments with an excitation beam and collecting light emitted by the fluorescent labels in three optical channels. The signals from three optical channels are evaluated to determine a DNA sequence for the target species. This evaluation can be done with a specifically programmed computer.

Upon detecting necessity to modify a control channel set to be assigned to a particular UE among the UEs, a Node B determines to modify a control channel set assigned into the UE to a new control channel set at a predetermined point of time to come. After determining to modify the control channel set, the Node B transmits an indicator indicating expected modification of the control channel set and information on the control channel set to be modified to the UE over a downlink.

Title: Method and apparatus using track scan data to qualify heads based on pes linearity
Inventor: SACKS ALEXEI H
IPC: G11B7/22
Filed: 2001-04-02
Abstract: A method and apparatus to qualify heads (110) to be used in disc drives (100). The method and apparatus collect a set of track scan data (1101, 1301) by moving the head across transitions (1004, 1204) in a track on a medium. The track scan data is changed based on a difference between a writer width of the head (1001, 1201) and a nominal track width (1002, 1202) to produce modified track scan data (1401, 1501). Position error signal data (1604) is then determined from at least some of the data in the modified set of track scan data (1401, 1501). The linearity of the position error signal data (1604) is used to qualify the head (110).

Title: Integrated circuit packaging process involving partial curing of bonding material prior to chip attachment and molding step
Inventor: LIN CHUNG-HUNG
IPC: H01L21/58
Filed: 2003-11-26
Abstract: A packaging process for improving the effective chip-bonding area is disclosed. An A-stage liquid paste is formed on a substrate 110 and partially cured (e.g. by heating the substrate) to become a B-stage film layer 122. A chip 130 is bonded to the substrate using the B-stage layer 122, and electrical connections 140 are formed. During the bonding step the temperature of the B-stage layer 122 is higher than its glass transition temperature, but the B-stage layer 122 is not fully cured. A molding compound 150 is formed on the substrate 110 with a packing pressure of 1000-1500psi, which is larger than the pressure used to attach the chip 130. The pressure causes the B-stage layer 122 to be closely compressed in order to improve the chip bonding area. The B-stage layer 122 and the molding compound 150 are simultaneously cured at a temperature of 150-200{ during the molding step.
