Title: Generating pulses in a switching amplifier
Inventor: WITCHARD CLYDE
IPC: H03K5/13
Filed: 2006-09-05
Abstract: A class D or switching amplifier has a modulator which generates positive 40 and negative 44 pulses, in response to an input signal. The frequencies of the negative and positive pulses are controlled independently, and both pulses are combined to form a composite stream 48 which, when low-pass filtered (fig 2) gives an output which as an amplified version of the input signal. Timing of the pulses can be adjusted, to prevent positive and negative pulses occurring simultaneously (fig 8, 152). Pulse times are determined (fig 7, 128,130) by comparing a signal represented by a sequence of samples with a threshold value using an iterative method. If contiguous samples are close to a straight line, linear interpolation is used to decide when the threshold is reached, but if they are not more accurate interpolation generates new sample points around the threshold. The switching amplifier also comprises a timer (fig 7, 132,134) to generate pulses from a digital time value. The timer (fig 9) may comprise a low precision timer operated from a slow clock which triggers a second, higher precision timer, operated from a fast clock, that outputs a trigger event. The timer may also comprise a ring oscillator (fig 10) of inverters connected to a multiplexer (fig 11, 212) and the oscillator clocks a timer (fig 11, 202). The clocked timer and the multiplexer are loaded with the digital time and their outputs combined to provide a trigger. The amplifier has low switching losses, and is suitable for battery powered audio use.

Title: Use of carbonated water as a solvent for freeze drying, and method of purification comprising dissolution of material in carbonated water and freeze drying
Inventor: FABBRI OLIVER JEAN
IPC: A61P21/02
Filed: 2007-01-17
Abstract: Carbonated water may be used as a solvent for freeze drying. A crude organic compound, e.g. one comprising residual solvent, may be purified by dissolving it in carbonated water to form a solution and subsequently freeze drying the solution to yield the compound with a reduced level of residual solvent. The carbonated water preferably has a pH of less than 6 prior to dissolution and is optionally further carbonated during or after dissolution to restore a pH of less than 8. Prior to freeze drying, residual solvent may be reduced in an intermediate solvent removal step (e.g. by vacuum distillation). This process is particularly suited for the purification of organic compounds which are unstable in basic solution or are difficult to purify by recrystallisation (e.g. due to solvate formation), especially the basic steroidal pharmaceutical neuromuscular blocking agent, rocuronium bromide: <EMI ID=1.1 HE=45 WI=100 LX=555 LY=1449 TI=CF> <PC>This process may also be applied to the purification of tubocurarine, atracurium, cisatracurium, mivacurium, pancuronium, vecuronium and rapacuronium.

Filed: 2007-11-27
Abstract: A method of authenticating an authorised entity via the telephone network is disclosed. A telephone call is placed from a telecommunications terminal to a server that comprises a valuable resource and that only provides the resource to authorised entities. When the terminal has already demonstrated its authorisation to the server, the server indicates to the terminal that the terminal need not provide its authorisation credentials. In contrast, when the terminal has not yet demonstrated its authorisation to the server, the server indicates to the terminal that the terminal does need to provide its authorisation credentials. The server indicates to the terminal whether or not it needs to provide its authorisation credentials by deliberating waiting to establish the call with the terminal, wherein in the length of the wait is indicative of whether or not the terminal needs to provide its authorisation credentials.

Title: Position sensor offset for an electric machine
Inventor: CELIK TUNCAY
IPC: H02K29/08
Filed: 2009-04-04
Abstract: A control system for an electric machine 8, comprises a position sensor 13, a drive controller 16, a gate driver module 12 and an inverter 11. The drive controller generates one or more control signals S1-S4 to control excitation of the winding in response to edges of a signal output by the position sensor.
