Title: Down-mixing a stereo speech signal to a mono signal for encoding with a mono encoder such as a celp encoder
Inventor: GIBBS JONATHAN
IPC: G10L19/008
Filed: 2007-09-25
Abstract: An encoding apparatus comprises a frame processor (105) which receives a multi channel audio signal comprising at least a first audio signal from a first microphone (101) and a second audio signal from a second microphone (103). An ITD processor 107 then determines an inter time difference between the first audio signal and the second audio signal and a set of delays (109, 111) generates a compensated multi channel audio signal from the multi channel audio signal by delaying at least one of the first and second audio signals in response to the inter time difference signal. A combiner (113) then generates a mono signal by combining channels of the compensated multi channel audio signal and a mono signal encoder (115) encodes the mono signal. The inter time difference may specifically be determined by an algorithm based on determining cross correlations between the first and second audio signals.

Title: Top-down protein analysis in mass spectrometers with ion traps
Inventor: HARTMER RALF
IPC: H01J49/02
Filed: 2007-10-16
Abstract: The invention relates to the structural analysis of proteins in the molecular mass range from approximately 5 to 100 kilodaltons, without prior enzymatic digestion to small peptides, in mass spectrometers that operate with ion traps. Since the ionization of large proteins by electrospraying or similar processes always creates highly charged analyte ions, the invention combines fragmentation of the analyte ions with partial deprotonation. It is favourable to apply deprotonation prior to fragmentation, although the invention is not restricted to this. The aim is to generate the most evenly distributed mixture possible of fragment ions having between one and n charges, where n is a number between three and about eight. From this mixture of fragment ions it is possible to record a mass spectrum which demonstrates a sequence coverage that far exceeds the mass range of the mass analyzer for singly charged ions. Both ergodic and electron-induced fragmentation may be carried out.

Title: Improvements in an electrostatic trap
Inventor: MAKAROV ALEXANDER
IPC: H01J49/42
Filed: 2006-06-05
Abstract: An electrostatic trap such as an orbitrap is disclosed, with an electrode structure. An electrostatic trapping field of the form U'(r,  d  ,z) is generated to trap ions within the trap so that they undergo isochronous oscillations. The trapping field U'(r,  d  ,z) is the result of a perturbation W to an ideal field U(r,  d  ,z) which, for example, is hyperlogarithmic in the case of an orbitrap. The perturbation W may be introduced in various ways, such as by distorting the geometry of the trap so that it no longer follows an equipotential of the ideal field U(r,  d  ,z), or by adding a distortion field (either electric or magnetic). The magnitude of the perturbation is such that at least some of the trapped ions have an absolute phase spread of more than zero but less than about 2   f  radians over an ion detection period Tm.

Title: Cryptographic architecture with instruction masking and other techniques for thwarting differential power analysis
Inventor: SHU DAVID B
IPC: H04L9/00
Filed: 2005-06-07
Abstract: The invention prevents information leakage attacks that utilise timeline alignment such as Differential Power Analysis (DPA). Data processing in a CPU is concealed by inserting a random number of instruction fetch cycles during execution of a program and, while the random number of instruction fetch cycles are occurring, mimicking the power consumption associated with fetching instructions from memory, executing the instructions in program sequence, and writing results to memory registers. The mimicking of power consumption is achieved by the inclusion of an additional dummy register 222, an additional AND gate to emulate AND gates 221 associated with conventional registers 221, and a pseudo program counter 232 to emulate the operation of an actual program counter 230. At the conclusion of the random number of instructions, normal program execution recommences by re-fetching the same instructions which were initially fetched but this time updating memory locations in the normal way. The insertion of the random number of instruction fetch cycles is controlled by a Random Instruction Mask (RIM) control flag 202. Other embodiments are disclosed, including a cryptographic bus architecture that prevents usage of side channel information by randomly toggling the polarity of a target bit at a data bus driver.

Title: Improvements in electrical signalling systems
IPC: H04Q1/38
Filed: 1941-08-09
Abstract: 551,187. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., TAYLOR, R., and BAKER, G. T. Aug. 9, 1941, No. 10146. [Class 40 (iv)] In a system involving long non-repeatered lines, the reversals of current which occur upon the reply and upon the release of the called subscriber are detected by a pair of gridcontrolled gas-discharge tubes which are triggered into operation by an inductive kick through a transformer. The invention is applied to a system for " demand " working, in which an operator sets up long-distance calls by direct dialling. After plugging into the required junction, the operator throws her dialling key, whereupon relay DT pulls up and loops the junction. In the case of a short junction, straps would be removed to insert resistances YF, YO in the dialling circuit. Line relay A operates at the distant exchange followed by relay B which locks and prepares the incoming selector. A third winding of relay A is connected to the grid of a gasdischarge tube GDT3 and the fall of current at each impulse break produces an inductive kick which reduces the negative grid bias and causes ionization of the tube. Relay P operates in the anode circuit which is then opened to extinguish the tube by the response of the magnet RM. A mechanical impulse regenerator of the kind described in Specification 458,095 is employed to receive and retransmit the impulses, RM being its receiving magnet, but this is not essential. Moreover, the end of each impulse train is determined in the manner described in Specification 549,047 by a timing circuit comprising a neon tube NT in association with a continuously-charging condenser QF which is discharged at each operation of relay P. For the receipt of supervisory signals, a pair of gas-discharge tubes GDT1, 2 are coupled to the junction by a transformer TR. The reversal upon reply triggers the tube GDT2 and brings up relay D, the tube remaining conductive. Relay D completes the feed on the jack side, darkens the supervisory lamp and prepares the tube GDT1. The further reversal upon release therefore triggers the tube GDT1 and brings up relay RR, which disconnects D to relight the supervisory lamp. The opening of the loop across the junction produces the effect of a single impulse at the distant exchange, and relay B is unlocked after the timing circuit NT, QF has operated.
