Title: Vehicle air compressor
Inventor: WONG PAUL WAI KAN
IPC: F04B49/03
Filed: 1995-03-27
Abstract: A vehicle compressor comprises an electrically operated compressor (16) driven by a motor (14) arranged to be connected to the vehicle's electrical supply, output supply means (22) from the compressor for attachment to a vehicle tyre to inflate the tyre and pressure release valve means (42) subject to the output pressure from the compressor. The release means comprises a moveable valve urged by resilient means against a valve seat, a housing defining an enclosure into which air from the pressure release valve releases; and means for adjusting the pressure at which the release valve means opens. Adjustment is via a knob (56) mounted so as to be rotatably movable over a planar surface of the housing which carries a pressure - calibrated scale. Means (76) which detect the release of air into the enclosure (64) are arranged to de-energise the motor.

Title: Radar for vibration detection
Inventor: HARPER MARK FRANCIS LUCIEN
IPC: G01S13/32
Filed: 1996-02-08
Abstract: A radar set is able to measure vibrations of a body 6 whose displacements are far smaller than (eg one millionth of) a wavelength of the radio beam it transmits. The radar set incorporates a transmitting antenna 4 and a receiving antenna 8; the received signal is mixed 12, 13 with the transmitted signal to provide a Doppler signal. In order to detect small vibrations feedback path 22, 28, 26 allows the part of the received signal 9 which does not vary with the displacements of the body 6 to be cancelled out before it reaches the receiver 10; this is done by adjusting the phase and amplitude of the signal provided by the feedback path in network 22 (shown in more detail in fig 2) and can be done automatically (51, 52, 53, fig 3). The remaining signal is proportional to the displacements of the vibrating body 6 and so may be used directly as a measure of them.

Title: Noise output for a decoded speech signal
Inventor: CHAN DOMINIC SAI FAN
IPC: G10L19/005
Filed: 1997-03-01
Abstract: A speech decoder (201) is arranged and constructed to receive a plurality of speech parameters and decode the plurality of speech parameters into at least one fragment of decoded speech. A noise generator (205) is arranged and constructed to output a noise signal. Determining means (203) provide a decision as to whether the plurality of speech parameters represents unvoiced speech. A switch (209), operating together with the speech decoder, the noise generator, and the means for determining, is arranged and constructed to output the noise signal when the plurality of speech parameters represents unvoiced speech. A noise source (2051) e.g. a pseudo-random sequence generator applies a Gaussian noise signal to an LPC filter (2053) which spectrally shapes the noise signal with an estimate of the original speech spectrum envelope as provided by the LPC parameters provided by speech decoder (201). A filter (2055) adjusts the output energy of the noise signal to match the original decoded speech.

Title: Bed base with air chambers for water mattress
Inventor: CHUNG MING-CHUN
IPC: A47C27/08
Filed: 1997-05-02
Abstract: A water bed base 20 defines a number of container chambers 26 into which an equivalent number of water bed mattresses 10 are respectively removably inserted. Each container chamber is sealed and thus advantageously prevents any of the water bed mattresses which may be leaking water from leaking water outside of the water bed base. Further, the leaking water bed mattress, because it is removably inserted into the water bed base, may be individually replaced. Also, the water bed mattress has a plurality of air 12, 13, 17 and water 11 chambers, some having fluid baffles 16, 14 to restrict the free flow of fluids. Further, the water bed base has several air chambers 23. These chambers maintain the shape of the water bed while providing a regulator and an absorbing means of the pressure inside the water bed. Thus, user comfort is maximized.

Title: An arrow for a crossbow
Inventor: OSSEGE JOHANNES
IPC: F42B6/02
Filed: 1997-12-11
Abstract: The invention relates to an arrow for a crossbow comprising a tubular shaft formed of inner and outer tubes 4 and 5, the outer tube projecting beyond the inner tube at the front of the shaft and the inner tube projecting beyond the outer tube at the rear. The shaft allows different arrow tips 7 to be interchangeably inserted at the front, and yet always have the same properties of flight. On impact, the arrow tips are supported against the inner tube end and do not expand the shaft. At the rear 6, it is possible to push on (i) identical tail parts 13 that can be differently coloured and which are cast off in the case of a through shot, and (ii) a part 15 with a rubber buffer pad 16 insertable from the rear, which protects the string of the crossbow during the shot and prevents the arrow from being set into harsh vibrations. A cover shell 9 of different hunting tips, which is always the same in external shape, always ensures the same flight properties of the arrow, and hence a high accuracy of shot.

Title: Printing with different printer heads
Inventor: CHENG PETYER L
IPC: B41J2/175
Filed: 1998-01-16
Abstract: A printing method for use with a printer which reads and then outputs to a printer head a fixed number of bits at a time, permits the printer to use a printer head having a number of e.g. nozzles which is different from the fixed number of bits. Bit data corresponding to an image band to be printed is obtained, the band including multiple pixel arrays, the pixels in each pixel array being arranged in a manner similar to the nozzles. In a first loading step, bit data for m pixels of an i-th pixel array are loaded into a register in the printer head. In a second loading step, bit data for n pixels of an (i+1)-th pixel array are loaded into the register. Finally, the printer head is caused to print an array of dots based on the contents of a register which includes the bit data loaded pursuant to the first and second loading steps, the printed array of dots corresponding to the i-th pixel array. Whether a printer head is a monochrome or a color printer head is detected, with translation of color image data into monochrome image data controlled to occur only if the input image data is color image data and the detection means has detected a monochrome printer head.
