Title: Photodetector Circuit
Inventor: MARSHALL GILLIAN FIONA
IPC: H01L31/028
Filed: 2000-08-16
Abstract: A photodetector circuit (Figure 1, 10) has a readout circuit (Figure 1, MD1, MF1, and MR1) and is characterised by a CMOS component 12 and at least one epitaxial layer which is an active region of a photodiode detector APD1. The photodiode detector APD1 may have a first region of one conductivity type 16 incorporated in the CMOS component. The at least one epitaxial layer may have two epitaxial layers 16 and 18, one of which is substantially undoped 16, and the other of which is of opposite conductivity type 18 to that of the first region. The first region and the two epitaxial layers may be configured as a PIN diode. The undoped epitaxial layer may be a silicon germanium alloy (Figure 13), or a quantum well structure of the Si <SB>1-x</SB> Ge<SB>x</SB> material where the value of the compositional parameter x changes between successive layouts. Alternatively, a photodetector circuit (Figure 5) includes a readout circuit, and is characterised in that it includes an amplifier arranged to provide feedback to a transistor load in series with an avalanche photodiode detector (Figure 5, APD5) to stabilise the photodiode detector biased voltage. The photodetector circuit may include parasitic photodiodes connected in parallel with the avalanche photodiode detector. A cascode transistor (Figure 9) may be arranged to reduce the Miller Effect capacitance in a push -pull amplifier. A method of making a photodetector circuit incorporating a photodiode detector and an associated readout circuit is disclosed. The method includes the step of producing upon a CMOS circuit component at least one epitaxial layer providing an active region of the photodiode detector. A photodetector circuit which has a readout circuit, and at least one silicon germanium alloy region arranged for photoabsorption to which the circuit is responsive is disclosed.

Title: Handover of a mobile station between base stations without passing of the air interface encryption key over the air interface
Inventor: RAYNE MARK WENTWORTH
IPC: H04L29/06
Filed: 2000-09-27
Abstract: A technique for the handover of a mobile station 30,31,(44,45) between base stations 32,33,(39,40) in a radio communications system in which the mobile stations and base stations each derive an encryption key (DCK) for encrypting their communications to each other. On handover, the key derivation parameters used by a mobile station to derive the encryption key are passed to the new base station, which then uses the parameters to re-derive the encryption key. The mobile station can then communicate with the new base station using the original encryption key for that call. Preferably the new base station seeks the key derivation parameters for a particular mobile station from a database. The key derivation parameters passed to the new base station on handover preferably comprise only parameters previously transmitted over the air-interface. In this way handover of a mobile station between base stations is achieved, without passing of the air-interface encryption key over the air-interface.

Title: Mobile terminal power control in the event of a cdma base station fault
Inventor: SUZUKI TAKASHI
IPC: H04W52/04
Filed: 2001-04-12
Abstract: An increase in the transmission power level of an upstream signal from a mobile terminal due to a failure of a baseband processing section is inhibited and the interference of the upstream signal with upstream signals sent from other mobile terminals is prevented. If a failure occurs in a user correlation value detector 22-3 provided in a baseband processing section 22a of a transmitter/receiver 20, an abnormal operation signal is sent from a failure detector 22-9 that detects the failure to an alarm signal generator 22-5. When an alarm signal is sent from the alarm signal generator 22-5 which receives the abnormal operation signal to an alarm monitor 23, the alarm monitor 23 sends a decoding discontinuation signal to a decoder 22-4 and a power controller 22-6 generates a TPC bit instructing the mobile terminal to decrease the transmission power level of the upstream signal from the mobile terminal to a lower level. The generated TPC it is added to a downstream signal in a downstream data processing section 22-2 and the downstream signal is sent to the mobile terminal.

Title: A method and apparatus for determining the flow rate of a fluid through a pipe
Inventor: THURSTON ROBERT RICHARD
IPC: G01F1/7084
Filed: 2001-04-24
Abstract: The method and apparatus are particularly for determining the flow rate of a gas, which maybe natural gas, through a pipe, independent of the geometry of the pipe. The method involves discharging or injecting by unit (2) a known or determinable molar quantity of a tracer fluid, which maybe as a pulse, from a charge vessel (21) via valve (26) into a fluid flowing through a pipe. Control means (4), which maybe a portable computer, opens valve (26) and determines the quantity of tracer fluid discharged based on the change in pressure and temperature detected by sensors (24, 25). The flow rate of the fluid flowing in the pipe is determined by control means (4) dependent on the molar quantity of the tracer discharged and the measured concentration of the tracer fluid by detector (3) as a function of time. The concentration of the tracer fluid is preferably sampled continuously from when the tracer fluid first passes the detector (3) until all of the tracer fluid has passed the detector (3) and the sampled concentrations are integrated with respect to time. The concentration of the tracer fluid, which maybe helium, is preferably determined by measuring the thermal conductivity of the fluid mixture.
