Patent GB-2451470-A (GB)
Title: Multiple output DC-to-DC converter
Inventor: NOTMAN ANDREW
IPC: G05F1/62
Filed: 2007-07-31
Abstract: A DC-to-DC converter generates a plurality of power outputs at different voltages using a single inductor 33 and an arrangement of switches A to F enabling the input voltage to be connected to the inductor 33 in both forward and reverse directions. Power is supplied to an output during an inductor charge phase in which current flows from the input supply through the inductor to the power output, followed by an inductor discharge phase in which current flows from ground through the inductor to the power output, the current in the inductor at the end of the inductor discharge phase is detected and stored, and, before the next inductor charge phase for the same output, a slew phase is provided in which the input supply is connected across the inductor in either the forward or reverse direction, to alter the inductor current at the beginning of the inductor charge phase to be equal to the inductor current at the end of the previous discharge phase for that respective output. The inductor current can be regulated rapidly, enabling the converter to supply current to an output whose voltage is close to the input voltage. This arrangement reduces crosstalk between power outputs, and enables the converter to supply outputs having different power requirements. Preferably, the total length of time (slew phase plus inductor charge phase plus inductor discharge phase) for each power output is the same, which reduces the variable frequency noise generated by the converter. The converter may be used in portable devices such as an MP3 audio device (fig 2) which can receive power from a battery or from a computer USB connection (fig 1).

Title: Heat pipe for a solar collector
Inventor: WILLIAMSON THOMAS PATRICK
IPC: F24S10/95
Filed: 2008-04-07
Abstract: A heat pipe 2 comprises an evaporator section 5 comprising a radiation absorbing plate (6, fig.2), for absorbing solar radiation, and a portion of an elongate tube (7, fig.2) containing a working fluid, in thermal contact with the radiation absorbing plate, and an evacuated radiation transparent enclosure (8, fig.2). The heat pipe includes a condenser section 10 at a distal end of the elongate tube remote from the evaporator section. To achieve a desired temperature limitation of the working fluid within the condenser section, a flow control valve 20, comprising a valve head 22 and a valve seat 24, is provided between the evaporator section and the condenser section to selectively close communication between the sections when the temperature within the condenser section exceeds a predetermined maximum value. Preferably, a temperature sensitive member, in the form of a coil of memory metal 34' or bimetallic discs (34'', fig.7), acts to urge the valve head towards the valve seat to close the flow control valve. A return spring (38, fig.5) may be located around a pintle 30, acting between the valve head and a support plate 26, to bias the valve head away from the valve seat. In use, when the valve head is in its closed position, an increase in pressure within the evaporator section acts against the valve head to urge the valve head against the valve seat.

Title: Semiconductor gain medium which can generate THz radiation
Inventor: PEREIRA MAURO
IPC: H01S5/34
Filed: 2008-11-25
Abstract: A semiconductor gain medium for example, GaAs and AlGaAs with alternating intrinsic and p-doped regions or InGaAs-InP quantum well-multiple barrier structures are described which can generate THz frequency electromagnetic radiation. The gain medium is configured so as to have a valence band having a plurality of sub-band states. The energy spacing between a first sub-band state and a second sub-band state is such that a hole transitioning from the first sub-band state to the second sub-band state will emit TE mode electromagnetic radiation in the THz frequency range. A method of generating THz frequency electromagnetic radiation from the semiconductor gain medium is also described. A hole is introduced in a sub-band state of a valence band of the semi-conductor medium. The hole is allowed to transition into a lower energy sub-band state of the valence band of the semi-conductor medium and to emit TE mode electromagnetic radiation in the THz frequency range. The gain medium may be used in a vertical cavity emitting laser (VCSEL, 700 Figure 7). The invention may use k-space filtering resulting from intervalence transitions in semiconductor structures operating at high temperatures.

Title: Controller for a motorised vehicle
Inventor: SHARP NIGEL PETER
IPC: B60L15/20
Filed: 2009-04-21
Abstract: A controller and control method for a motorised vehicle such a wheelchair are provided. The motorised vehicle has at least two driven wheels 20, 25 driven independently by a motor arrangement, 40, 45 and the controller receives a number of input signals from a user input device 85 of the motorised vehicle. The controller comprises drive control circuitry 70 for generating control signals for controlling the driving of the driven wheels by the motor arrangement, the control signals being dependent on the input signals. Speed assist circuitry 75 is responsive to an indication of current consumed in driving the driven wheels to detect occurrence of a loading condition. On detection of occurrence of a loading condition, the speed assist circuitry is then arranged to boost at least one of the input signals in order to boost top speed in the presence of the loading condition. This significantly improves the control of the motorised vehicle in situations where the occurrence of the loading condition may otherwise prevent the vehicle from moving, as for example may occur when seeking to turn the vehicle at low speed. The controller may also include IR compensation circuitry 60.
