Abstract: A light beam emitted from a light source (1) is split into three light beams by diffracting the light beam by means of a diffraction grating (2). The three light beams are reflected by the first side (31) of a plane-parallel plate (3). The reflected light beams are projected onto an optical disk (100). The three signal light beams are reflected by the optical disk (100) and returned to the plane-parallel plate (3). The plane-parallel plate (3) transmits part of the signal light beams to a first photodetector (5) and reflects part of the signal light beams from the second side (32) and transmits the reflected light beams to a second photodetector (6). The first photodetector (5) receives the central light beam. The second photodetector (6) receives the side light beams. The overall size of the apparatus can thereby be reduced.

Abstract: The invention provides an inhaler for delivering a substance in a finely divided form from a storage chamber within the inhaler. The inhaler comprises a metering member operable to transfer a dose of the substance from the storage chamber (10) to an inhalation passage (15), the metering member having a frusto-conical metering surface (7) which is indented to provide at least one dispensing cup (8) and being moveable between a first position in which a dispensing cup (8) is presented to the storage chamber (10) to receive a dose of the substance and a second position in which a dose of the substance is presented to the inhalation passage (15) in an upwardly open dispensing cup (8). The body (4) of the inhaler comprises a seat having an annular, frusto-conical contact surface making sliding contact with the metering surface and defining a socket within which the metering member (6) is journalled for rotation between its first and second positions. The use of a frusto-conical metering member allows a good seal to be obtained between it and the seat and also makes the inhaler relatively compact.

Abstract: In the formation of microstructures, a preformed sheet of photoresist, such as polymethylmethacrylate (PMMA), which is strain free, may be milled down before or after adherence to a substrate to a desired thickness. The photoresist is patterned by exposure through a mask to radiation, such as X-rays, and developed using a developer to remove the photoresist material which has been rendered susceptible to the developer. Micrometal structures may be formed by electroplating metal into the areas from which the photoresist has been removed. The photoresist itself may form useful microstructures, and can be removed from the substrate by utilizing a release layer between the substrate and the preformed sheet which can be removed by a remover which does not affect the photoresist. Multiple layers of patterned photoresist can be built up to allow complex three dimensional microstructures to be formed.

Abstract: To form a ball bearing retainer (10) or cage, material is first formed into a flat ring. Ball receiving pockets (12) are formed in the flat ring leaving bridge material (14) between adjacent pockets. The bridge material between adjacent pockets is flattened such that the bridge material spreads to meet the adjacent bearing balls (30), thereby locking the retainer within a ball bearing assembly. The resulting substantially flat bridge (42) between adjacent reconfigured ball pockets (34) is then crimped such that ends of the bridge are moved slightly towards each other and pressure of the reconfigured ball pockets against the bearing balls is reduced. Forming of a separate bearing retainer or cage is also disclosed.

Abstract: The volume determining the compression ratio is formed by a combustion antechamber (8) and a chamber (4) over the piston and a further air chamber (14) storing the air required by the antechamber. The air chamber and antechamber are permanently connected by a passage (12), connected at regular intervals via a slot (17) to the air chamber. A plug (15) alternately shuts off the slot and the drilling (13) connecting the air chamber to the main chamber. A poppet valve (6) controls admission of fuel from a vaporising chamber (7). A further valve (9) controls admission of gas through a further passage (10). A vaporiser (24) heated by the exhaust manifold (25) may gasify liquid fuels. On the compression stroke air passes up the passage into the antechamber, diluting the rich mixture contained in it. During the power stroke, air from the air chamber scavenges the combustion chamber.

Abstract: A circuit is provided for rectifying an AC input voltage to provide a substantially constant DC output voltage. A composite input voltage is derived from the AC input voltage, which is composed of a scaled input AC voltage shifted by a selected DC bias voltage such that the entire range of such input signal voltages is contained within the supply voltages of detection circuitry which controls the rectifier circuitry. The detection is thus carried out during both the upper and lower excursions of the input AC voltage.

Abstract: The present invention discloses an apparatus and method for transmitting a data packet over a wireless network with improved security. Each transmitted message includes three segments. A first segment includes information identifying the originator of the message. A second segment includes a digital signature obtained by hashing and encrypting the data to be transmitted. A third segment includes the data packet. Upon receiving the message, a wireless receiving unit uses the information contained in the first segment to retrieve an encryption key and, thereby, identify the originator of the message. The wireless receiving unit then hashes and encrypts the received data packet according to the same hashing and encryption algorithms used to form the digital signature. The resulting encrypted hashed version of the data packet is compared to the received digital signature in order to establish the integrity of the received data packet.
