Title: Electronic throttle monitoring and power limiting
Inventor: PALLETT TOBIAS JOHN
IPC: F02D41/26
Filed: 1997-08-05
Abstract: Electronic throttle monitoring of a powertrain system including an electronic powertrain control module (16), and an electronic throttle control (18), includes an independent processor receiving signals shared with the powertrain control module (16) from sensors (19) and actuators (21) on the vehicle. The monitor operates in a monitoring mode to detect faults occurring in the powertrain or the powertrain control module, and determines whether mitigating conditions occur in conjunction with detected power output greater than power demand. In the event that these mitigating conditions are not detected, the monitor operates in a limiting mode to actuate decreases in power output below the level of power demand. These actuation may occur by invoking powertrain system (17) protection with the powertrain control module (16) or by otherwise effecting demands to the electronic throttle control. For example, the monitor may limit the throttle plate angle, the spark advance or the injection of fuel to the cylinders, or shut down engine operation completely.

Title: A low loss optical demultiplexer
Inventor: JANG JOO-NYUNG
IPC: H04B10/00
Filed: 1997-12-03
Abstract: An optical demultiplexer, for use in low-power, high density wavelength division multiplexing (WDM) optical transmission systems, comprises a plurality of serially connected optical wavelength filters (figure 9). Each filter consists of two optical couplers 510, 520, and two wavelength reflectors. When an optical signal I 1 , having a plurality of wavelength components (# 1 , # 2 , ...# n ), is input to port 511 the first optical coupler 510 splits it into two signals I 2  and I 3  which are output by ports 513 and 514. respectively. Upon reaching the wavelength reflectors one component of these signals having a predetermined wavelength # i  is reflected back to the first coupler 510 as signals I 4  and 15. The first coupler combines these signals and outputs them as signal I 9 . The remaining components of signals I 2  and I 3  are output by the wavelength reflectors as signals I 6  and I 7 . These signals are recombined by the second coupler 520 and output as signal I 8 . In this way the filter separates out signals having a predetermined wavelength # i  with a minimal loss of signal intensity. Preferably the wavelength reflectors are fibre grating reflection filters. An embodiment using a third coupler and two more wavelength reflectors is also disclosed (figure 10).

Title: Linear motors and bearings therefor
Inventor: HOOLEY ANTHONY
IPC: H01L41/09
Filed: 1998-02-09

The motor may operate upon piezoelectric, magnetostrictive, hydraulic, pneumatic, thermal, shape memory or biological principles. The bearings 103, 104 preferably consist of toroidal elastomeric fluid- or foam-filled "bags". The motor is preferably used as a loudspeaker drive unit.

Title: Generating bias signals
Inventor: BRENNAN MARTIN JOHN
IPC: G11B5/03
Filed: 1998-04-03
Abstract: The quality of a recorded signal can be vastly improved by recording with it what is known as a "bias" signal. The bias signal is commonly generated in the most economical way using a tuned circuit, and thus is sinusoidal in form; there are, however, substantial advantages in employing a significantly non-sinusoidal waveform for the bias signal. The present invention proposes a way in which such a bias signal can be formed; by using a succession of sample digital values (taken from some suitable source thereof, such as a Read Only Memory), which are applied them to a Digital-to-Analogue Converter (DAC), say, there may be constructed a bias signal with a waveform determined simply by the stored and selected digital values - a waveform of a shape, frequency and amplitude most suited to the task at hand and the prevailing circumstances.

Title: Venting a waterbed
Inventor: HSIA YU CHUN
IPC: A47C27/08
Filed: 1998-10-14
Abstract: An air vent for a waterbed includes a float 3 which prevents water loss while allowing air venting. The device includes an exhaust port attached to the waterbed and having vents 231,24. Float 3 is inside the body of the port and rises when water enters the vents 231,24. The body of the float carries convex strips 32 to minimise sticking. Vent hole 21 in the body allows air to escape but is blocked by the conical end 312 of a soft plug 31 at the top of the float when the float rises. Shoulders 311 on the plug prevent the conical end jamming in the vent 21. A similar plug (31', Fig 6) in the base of the float may block the vent(s) to the waterbed interior when the float falls to prevent air being sucked back into the bed. A cap 22 is screwed to the body.

Title: Method for crystallizing amorphous silicon layer and method for fabricating tft
Inventor: PARK WON-KYU
IPC: H01L21/77
Filed: 1999-06-08
Abstract: An active layer commonly used in a thin-film-transistor is made by irradiating an amorphous silicon layer with a laser source at an energy density sufficient to induce substantially complete melting to form a melted region and an unmelted region. The melted region of the amorphous silicon layer is solidified with a lateral grain growth from the unmelted region to the melted region. Then the amorphous silicon layer is translated relative to the laser source. In such an apparatus, the laser source is prepared by emitting a laser beam through a mask 160. The mask 160 has a plurality of transparent regions 162 which comprises slits arranged adjacent to or next to each other and separated by a predetermined distance in certain applications. Such pattern may include contiguous chevron-shaped lines with curved apexes. Alternatively, the pattern includes slim rectangular apertures or dots. The size of the crystal grains may be increased by rotating the pattern through 90 and repeating the procedure.

Title: An electronic lamp ballast with a minimum frequency of 400kHz
Inventor: TYSON LAWRENCE SAMUEL
IPC: H05B41/292
Filed: 1999-11-18
Abstract: An electronic ballast for a high intensity discharge lamp which has electrodes, the ballast produces a variable high frequency output of the order of 400 to 1500 kHz. The circuit consists of a resonant inverter tuned to increase the voltage at startup to ignite the lamp whilst the ballast limits voltage and current drawn. The lamp operates above its acoustic resonance so that it appears to the supply as an inductor (see figures 3 to 5) and to avoid damage to the bulb by an arc impinging on the internal surface of a burner. The lamp is started by reducing the frequency from a turn on frequency ST ON until an arc occurs at the ballasts resonant frequency PF, the frequency is then decreased to a dwelling frequency DWF to allow the bulb stabilises before the frequency is increased to a steady state value SF. The rate of varying the frequency in the circuit is above 50Hz to avoid any acoustic resonance developing and to remove any perception of lamp flicker.
