Title: A property based attestation system uses a zero knowledge proof to attest to the integrity of a TPM equipped computing device without disclosing configuration
Inventor: CHEN LIQUN
IPC: G06F21/57
Filed: 2007-07-09
Abstract: According to one exemplary embodiment of the present invention, a trusted computing platform (TCP) i comprises a host process Hi and a trusted platform module (TPM) Mi. The TCP responds to a challenge Nv 620 from a remote verifier V, to prove that the TCP has a configuration specification and respective properties that can be trusted by the verifier. According to the exemplary embodiment, the TPM generates a digital signature   s  M signed on a commitment Ci that commits to the TCP having a trusted configuration specification from a set of trusted configuration specifications 610 previously agreed by both the host and the verifier. Then the host uses the signed commitment Ci to generate a ring signature   s  r. The verifier is convinced that the TCP has trusted properties by verifying both the TPM signature   s  M and the ring signature   s  r, without the host having to reveal its configuration specification.

Title: A CMOS output buffer with ESD protection
Inventor: JEON CHAN-HEE
IPC: H01L27/04
Filed: 2004-12-30
Abstract: The pullup and pulldown sections in each output buffer are fed from separate power rails 40,46;42,48;44,50 so that a positive ESD impulse on any I/O pad cannot couple through the pull-up circuit MP10 to the gate of the pull-down cascode device MNA and cause gate voltage induced current crowding (GVICC). The pulldown circuit in each block shares a common supply with the pullup circuit in adjacent blocks. Positive ESD impulses on the I/O pad may be discharged by parasitic lateral NPN transistors associated with the pull-down NMOS transistors (figure 2).

Title: Closeable open cell foam for downhole use
Inventor: WOOD EDWARD T
IPC: E21B33/12
Filed: 2007-07-05
Abstract: A downhole packer or sealing device uses a swelling sealing element that is initially held in a compressed state. Exposure to well or other fluids occurs downhole as the initial restraint on the element is overcome. The element takes on well fluids as it resumes its relaxed position or swells. The element (10) is preferably an open cell material such as foam and has another material in its passages (12). The material in the passages, when exposed to well fluids, itself grows in size and can get harder. It blocks or seals the passages (16) in the foam so that the swollen foam becomes more like a closed cell material and can retain a seal against a greater range of operating conditions than had its passages remained open or unobstructed with another material.

Title: Fixed-position automatic stop control for an electric vehicle
Inventor: OISHI RYOICHI
IPC: B60T7/12
Filed: 2009-06-01
Abstract: A fixed-position automatic stop control means of a control system for controlling an electric vehicle having stored in advance a full-electric brake deceleration pattern capable of performing deceleration within the range of brake force obtained by the electric energy regeneration of a main motor. The vehicle is stopped at a target position via the full-electric brake deceleration pattern. By performing the fixed-position automatic stop control using only the regenerative brake, it becomes possible to prevent futile consumption of kinetic energy by the air brake, and since the frequency of use of the air brake is reduced, the abrasion of the brake shoe can be suppressed. The vehicle may have a plurality of patterns, either for the gradient/curve of different locations and/or a constant brake force pattern. The deceleration pattern may be automatically or manually switched.

Filed: 2009-06-03
Abstract: A receiver detects and recovers data from Orthogonal Frequency Division Multiplexed (OFDM) symbols, , the time domain OFDM symbols including a guard interval. The guard interval of the OFDM symbols is one of a plurality of predetermined temporal lengths. The receiver includes a correlator operable to correlate the time domain samples at a separation determined in accordance with the samples of the OFDM symbols and for each of a plurality of possible guard intervals combining the correlated samples for a period equal to the guard interval, for a plurality of consecutively received OFDM symbols, to form for each of the possible guard intervals a correlation output value, and a guard interval identifier arranged to receive the output from the correlator and to identify one of the guard intervals used for the received OFDM symbols from the correlation output value for each of the plurality of possible guard intervals. Accordingly in a system such as DVB-T2, where the guard interval is provided in signalling data communicated with the OFDM symbols, the guard interval can be detected without or before the signalling data is detected, thereby reducing a time for detecting the data conveyed by the OFDM symbols or the guard interval and/or improving an integrity with which the guard interval and therefore the data can be detected.

Title: GPS multipath reduction
Inventor: CHANSARKAR MANGESH
IPC: G01S19/22
Filed: 2009-08-26
Abstract: In order to reduce the effects of multipath signals in a GPS receiver, pseudorange measurements are generated from received satellites signals. These are processed to reduce pseudorange residuals (i.e. errors, innovations) based on statistical modelling and/or a knowledge of the receiver's position (e.g. from INS) in order to remove multipath errors, and navigation solutions are computed from these. Modelling may take into account the elevation of the satellites, as multipath is more likely in urban canyon at low elevations. A plurality of statistical models may be used, with the most suitable one being selected.

The compound BR2R1 may be formed by reaction of a mixture of compounds BR3 and BR13, or by reacting compounds BR3 or B2HnR6-n, where n is 1 to 6, with olefines of the formula Ar-Cm(Rc)2m-1 or (Rc)2m-1Cm-Ar-Cm(Rc)2m-1 in which Ar is an aromatic hydrocarbon radical, Rc a hydrogen atom or a hydrocarbon radical and m is 2 or an integer greater than 2. Formation of the compound B R2R1 may take place at a temperature of from 120 DEG  to 200 DEG C. with evolution of olefine. The examples also disclose the preparation of starting material BR2R1 from an aryl-substituted olefine and N-triethyl borazane. Specification 847,518 is referred to.

Title: Apparatus for producing an electrical output signal having a parameter which is linearly representative of the value of an unknown resistance
IPC: G01R27/14
Filed: 1974-03-06
Abstract: 1500695 Measuring resistance SOLARTRON ELECTRONIC GROUP Ltd 5 March 1975 [6 March 1974] 10002/74 Heading G1U . In a resistance or conductance measuring system an integrator is first driven positively from zero by a first voltage that varies non-linearly with the parameter being measured and then driven negatively back to zero by a second voltage which is a linear combination of a fixed reference voltage and the first voltage, the linear combination being so chosen that the ratio of the time taken for the integrator output to return to zero to the time for which the integrator was driven positively is linearly proportional to the parameter being measured. The invention is essentially an adaptation of the familiar dual-ramp A-D converter so as to eliminate the effect of the finite input impedance of such a converter when the converter is used to measure the voltage across an unknown resistor produced by a reference current. As shown in Fig. 1 for measuring resistance a constant current I c  is applied to a resistor R x  to be measured. Because of the finite input impedance R1 of a buffer amplifier 22, its output voltage V 1  does not vary linearly with R x . During a first phase of the measuring process, with a lead 68 from a control counter 62 marked, the voltage V 1  is applied, via a switch S1 to drive an integrator 32, Cl positively, 74, Fig. 2, for a fixed period To determined by a counter 46. At the end of the fixed period To, when counter 46 produces an overflow 58, the control counter is advanced to its next stage 69 and the integrator 32, C1 is driven negatively by a combination of a reference voltage 33 and the original voltage V 1  via switches 52 and 53. When, after a time T, the integrator output returns to zero, this being detected by a threshold circuit 38, the contents of the counter 46 are staticized 52 and displayed 56, and it is shown in the Specification that by appropriately choosing the input resistor to the integrator, i.e., by appropriately choosing the linear combination of the reference voltage and the original voltage V 1  that is used to drive the integrator back to zero, the time T can be made to be linearly proportioned to R x . By applying a constant voltage, rather than a constant current, Fig. 4 (not shown) to the resistor Rx, its conductance can be measured.
