Publication number: 20050128311Abstract: An image capture device is described having a remote photograph mode in which images can be captured without physical contact with the device. The device activated by the user speaking a keyword. The image capturing device is arranged so that after being initialised in the remote capture mode of operation, it enters a standby state for a period of time in which it is unresponsive to utterances and, after a period of time sets itself into a listening state in which it can capture images in response to detecting spoken keywords.Type: ApplicationFiled: September 10, 2004Publication date: June 16, 2005Applicants: Canon Research Centre Europe Ltd., Canon Europa N.V.Inventors: David Rees, Robert Anthony Fraser, Takashi Saito

Patent number: 6794865Abstract: A method and system for detecting an anomaly in a fluid system, comprising exposing a sample of the fluid system to a first, non-oscillating magnetic field, simultaneously exposing the sample to a second, oscillating magnetic field orthogonal to the first field, modulating one or both of the magnetic fields, and detecting and capturing a resulting NMR signal from the sample. An analysis of the captured signal, typically involving transformation of the signal into an NMR frequency domain spectrum, can be performed to look for specific changes in the signal indicative of the presence of a particular anomaly.Type: GrantFiled: September 12, 2001Date of Patent: September 21, 2004Assignee: Rolls-Royce PLCInventors: Kenneth Richard Astley, Paul Anuzis, Ian Colin Deuchar Care, Terry Alan Moore, Peter Gordon Morris, Paul David Rees

Patent number: 5953190Abstract: An electrostatic discharge (ESD) protection circuit for an output transistor coupled to an I/O pin of an integrated circuit, including a logic circuit having at least one data input, a tristate enable input, and an tristate output coupled to a gate node of the output transistor wherein the tristate output is placed in a high impedance state in response to the tristate enable input. The ESD protection circuit also includes a tristate enable circuit which drives the tristate enable input according to the presence or absence of an ESD event on the I/O pin. During normal operation, the tristate enable circuit applies a first logic level to the tristate enable input such that the tristate output of the logic circuit is placed in a low impedance state, and during an ESD event on the I/O pin, the tristate enable circuit applies a second logic level to the tristate enable input such that the tristate output of the logic circuit is placed in a high impedance state.Type: GrantFiled: May 2, 1997Date of Patent: September 14, 1999Assignee: Cypress Semiconductor Corp.Inventors: David Rees, James Lutley, Sandeep Pant

Patent number: 5841132Abstract: An optical displacement sensor is used to measure the rotary displacement between two shafts which rotate together. By connecting the shafts together by means of a torsion bar, the sensor may be used to measure transmitted torque. The sensor comprises first and second coaxial discs mounted on the shafts and having slots formed therein. A light source directs light through the slots onto an array of photodetectors and a data processor determines the displacement or torque from the positions on the array of images of the slot edges.Type: GrantFiled: May 9, 1997Date of Patent: November 24, 1998Assignee: Lucas Industries public Limited CompanyInventors: Steven John Horton, Adrian Leslie Trace, David Rees

Patent number: 5821770Abstract: A method for varying the type of function selected on a chip (for example, after completion of manufacturing) may include the steps of providing predetermined fuse arrangements which individually or in combination correspond to each type of function on the chip and providing disable control lines having fuses to each of the predetermined fuse arrangements. When one of the types of circuits is selected, the predetermined fuse arrangement individually or in combination corresponding to that selected type of function is blown. The blowing of fuses may change the functionality of the chip directly or may perform a complex procedure such as controlling a portion of a decoding scheme which may radically change the function of the chip. To prevent further blowing of predetermined fuse arrangements, the fuses in disable control lines to each of the predetermined fuse arrangements may be blown, eliminating further selection of types of function.Type: GrantFiled: April 30, 1996Date of Patent: October 13, 1998Assignee: Cypress Semiconductor CorporationInventor: David Rees

Patent number: 5781034Abstract: An output buffer having a reduced-swing output includes a p-channel pullup transistor as the primary pullup device. A biasing circuit is provided so as to bias the gate terminal of the pullup p-channel transistor to a predetermined level. The predetermined level is effective to cause the p-channel pullup transistor to shut off when the output of the buffer reaches a reduced magnitude output level (V.sub.OH). In the disclosed embodiment, the biasing circuit includes an n-channel transistor connected between the gate and drain terminals of the p-channel pullup transistor. The biasing circuit also includes a p-channel transistor having a source terminal connected to V.sub.cc, and a drain terminal connected to the gate of the pullup transistor. When the output of the buffer is desired to be in a logic high state, both of the biasing transistors are "ON.Type: GrantFiled: July 11, 1996Date of Patent: July 14, 1998Assignee: Cypress Semiconductor CorporationInventors: David Rees, Sandeep Pant

Patent number: 5559447Abstract: An output buffer with a variable output impedance is described. The buffer is designed so that the output impedance is set relatively low during the initial portion of the output transition in which the step would occur. The output impedance is increased near the end of the transmission to approximate the characteristic impedance of a transmission line driven by the buffer. Specifically, a first feedback circuit in the variable impedance output buffer outputs a first control signal in a first state during a first portion of the output transition. The first feedback circuit outputs the first control signal in a second state during a second portion of the output transition after the first portion. A first switched resistive element receives the first control signal from the first feedback circuit. The first switched resistive element increases the output impedance of the buffer in response to the first control single being in the second state.Type: GrantFiled: November 17, 1994Date of Patent: September 24, 1996Assignee: Cypress SemiconductorInventor: David Rees

Patent number: 4065782Abstract: A field-effect transistor (FET) for use at microwave frequencies has electrodes which act as transmission lines. Gate electrodes can comprise a narrow operative part between the source and drain electrodes which provides gating action, and a gate supply part which lies outside the source and drain electrodes and is connected to the operative part by a plurality of connections distributed along its length. In one form the device can be used as an amplifier and as such is capable of providing higher power handling capacity than conventional FETs, since the device can be extended in size and phase differences between various parts of the device compensate for one another. Other forms and applications are disclosed as a modulator and as a convoluter.Type: GrantFiled: October 15, 1976Date of Patent: December 27, 1977Assignee: The Secretary of State for Defence in Her Britannic Majesty's Government of the United Kingdom of Great Britain and Northern IrelandInventors: Kenneth Walter Gray, Huw David Rees
