Title: Authentication method using a third party
Inventor: MCDIARMUID ALISDAIR
IPC: H04L9/32
Filed: 2007-10-05
Abstract: Authentication in an ad-hoc network is established between a first device (for example a service-requesting device) and a second device (for example a service-providing device) using a third device (a peer device). An authentication request is transmitted from the first device to the second device. The second device transmits a query message to at least one third device (i.e. peer device). If the peer device has previously been authenticated with the first device, the peer device sends an authentication credential, for example an authentication key, to the first and second devices. Upon receiving the authentication credential, the first device sends the authentication credential to the second device. The second device then compares the authentication credential received from the first device with the authentication credential received from the third device, and authenticates the first device with the second device if the authentication credentials match. Preferably the authentication credential from the third (peer) device to the first device is encrypted.

Title: Adaptive decision threshold setting circuit, preferably with high and low thresholds
Inventor: CHOW FUN KOK
IPC: H04B10/158
Filed: 2007-11-19
Abstract: An optical receiver includes a photodetector assembly 26, a hold circuit 42, a threshold generating circuit 44, 45, and a signal generator 43, which acts as a decision circuit. The photodetector assembly generates a photo signal and the hold circuit stores a potential related to the maximum amplitude of the photo signal. The hold circuit may for example be a capacitor (52, Fig. 4). The threshold generating circuit generates a high threshold signal related to the stored potential. The signal generator generates an output logic signal (e.g. a binary output) that changes state when the photo signal crosses the high threshold. Preferably, there is also an adaptive low threshold which triggers a change of state of the output signal. The low threshold may be set to a minimum threshold value when the stored potential is less than a predetermined potential. This can be achieved, for example, using a current source (78, Fig. 5). The receiver may form part of an optical coupler.

Title: Wall-mounting device for CDs cases or similar
Inventor: JONES SAMUEL NICHOLAS
IPC: A47B47/00
Filed: 2008-01-19
Abstract: A device 30 for supporting at least two flat rectangular objects 32 against a wall having a rear planar wall (2, Figure 2e). Slots 12, 14 are defined in the upper two quadrants of the device 30 for receiving part of a flat rectangular object such as a CD case. The device is preferably attached to the wall by a double sided sticky pad (24, Figure 2f) or other conventional means. A CD case may be lowered into a pair of mounting devices 30 so the lower left and right corners enter the slots 12, 14. A third device 30 may then be attached to the wall above the CD case and lower face 20 may receive a top corner or an edge along an engagement face (18, Figure 2c). Slots 12, 14 may be wider than the thickness of object 32 so object 32 may be pivoted about its lower edge.

Title: Cryogen vessel comprising a pressure relief valve
Inventor: MANN NICHOLAS
IPC: F17C3/08
Filed: 2008-04-16
Abstract: A cryogen vessel 2, containing a liquid cryogen 3 such as helium, comprises a pressure relief valve 11 situated in the cryogen vessel wall to vent pressure out of the cryogen vessel when the valve opening pressure is exceeded. The valve opening pressure is independent of an environmental pressure, and is preferably set to open at a pressure of 110 kPa (16 psia). A pressure control system 13, 15 is provided to control the pressure in the cryogen vessel so as to maintain a substantially constant positive pressure differential, for example 700 Pa (0.1 psi), relative to a variable environmental pressure, such as atmospheric pressure. A sensor 16 may be used to monitor the ambient environmental pressure and provide an output to the pressure control system to control the pressure in the cryogen vessel. Preferably, the cryogen vessel houses a superconducting magnet 4 of a magnetic resonance imaging (MRI) scanner 1. In use, a processor 15 in combination with an absolute pressure sensor 14 and an ambient environmental pressure sensor 16 may be utilised to drive a pressure controller 13 to provide as large a pressure buffer as possible before a pressure relief valve is opened, thus ensuring that cryogen is not lost unnecessarily.

Title: Inhibiting wheelchair operation whilst determining yaw rate sensor zero point offset
Inventor: LEWIS JASON
IPC: A61G5/04
Filed: 2007-03-30
Abstract: The invention relates to the measurement of zero point offset of a yaw rate sensor so that the offset of the yaw rate sensor is measured accurately so that the yaw rate and the rate of turn of the vehicle is sensed efficiently and accurately. The vehicle may be an electric vehicle such as a wheelchair. A control system measures the output of the yaw rate sensor when the vehicle is at rest and then tests the measured output in accordance with test criteria to determine if the measured output is reliable. If it is determined that the measured output is reliable, the control system uses the measured output to determine a value for a zero point offset of the yaw rate sensor. Whilst doing so it inhibits the vehicle from being operational. The control system then enables the vehicle to be operational after the value for the zero point offset has been determined.

Title: Improvements in the stabilization of microwave oscillators
IPC: H03L7/26
Filed: 1949-04-14
Abstract: 665,390. Automatic frequency control systems. RADIO CORPORATION OF AMERICA. April 14, 1949 [June 25, 1948], No. 10197/49. Class 38 (iv). A microwave oscillator is stabilized in frequency by modulating part of its output to produce sidebands, and passing one or both, with or without the carrier, through a body of gas 14 exhibiting molecular resonance adjacent the oscillator frequency; then demodulating the output to obtain the modulation frequency shifted through a phase angle,due to the gas, relative to the modulator, and using a phase comparator to derive a D.C. voltage, corresponding in magnitude and sign to the phase shift controlling the oscillator frequency. The gas preferably acts to vary the phase of both sidebands to produce a resultant differential phase shift and may be contained at low pressure in an enclosure in a wave-guide or coaxial line. The relative variation in amplitude produced being small may be disregarded. The gas may be ammonia, carbonyl sulphide or a methyl halide. Demodulating may be effected by beating the gas cell output, after phase shift, with the oscillator frequency. In Fig. 3, the gas cell 14 is contained between two magic Tees, with the modulator output applied to crystal rectifiers 23 in opposite closed arms of the T and the oscillator frequency at 21. The lower T comprises similar rectifiers 28 oppositely poled to produce phase addition of their output, balanced demodulation being effected by an input of the oscillator frequency at 27. For low power oscillators, Fig. 4 (not shown), modulation and demodulation may be effected by crystals respectively located before and after a gas cell in a wave-guide output of the oscillator. Alternatively a beat oscillator, Fig. 5 (not shown), may beat with carrier frequency outputs of the modulator and demodulator to produce equal low frequencies for phase comparison. One frequency may be used to produce two trains of pulses of opposite polarity, symmetrically staggered in phase, superimposed on a saw-tooth wave derived from the other frequency in a combining circuit comprising a rectifier bridge from which is derived the phase-shift measuring D.C. voltage. This voltage may be applied to the reflector electrode of a reflex klystron or the control grid of a magnetron.
