Title: Minature silicon accelerometer and method
Inventor: O'BRIEN BENEDICT BUTLER
IPC: G01C19/56
Filed: 1991-12-23
Abstract: A miniature accelerometer is fabricated using integrated circuit manufacturing and silicon micromachining techniques to form a closed loop, force balance sensor utilizing a silicon proofmass 16 formed from and connected to a layer of silicon 24 by a split flexure 22 etched therein. Sensor circuitry 14 detects AC signals coupled from the proofmass to a pair of electrodes 30, 32 formed on glass layers 26, 26 anodically bonded to the silicon layer. A DC restorative force is applied to the electrodes 30, 32 in response to the detected AC signals to balance acceleration forces applied to the proofmass. The sensor design is highly symmetrical. The proofmass receives applied voltages from DC bias source 35 and AC source 38, the resultant signals on electrodes 30, 32 being fed to amplifier 60 via a diode quad bridge. The amplifier output signal, at point 34, is of magnitude and sign corresponding to the sensed acceleration and is fed back to the electrodes 30, 32 (via an inverter 62 in the latter case). Conductive guard bands 64, 66 are provided on the glass layers 26, 28 around the electrodes. To prevent the proofmass touching one of the electrodes if the device is under acceleration at start-up, the guard electrodes have inward fingers 74 - 77 corresponding to cut-outs in the electrodes, and contact posts are provided on the proofmass as at 78, 79, fig. 3. <IMAGE>

Title: An arrangement for mounting a cab structure to a vehicle frame
Inventor: KEECHNER DAVID M
IPC: B62D27/04
Filed: 1994-02-28
Abstract: Cab (16) and rollover structures (18) are useful for protecting an operator while operating a vehicle. When an integral cab rollover structure (18) is used it is necessary to provide a mount (26) which will isolate the structure from the frame (12) to reduce vibration and noise and also to provide a solid construction to transfer loads during rollover. The subject mounting arrangement (26) will provide a mounting structure which will isolate the cab rollover structure (18) from the frame (12) in a normal first operating condition to reduce noise and vibration within the cab (16). In a second condition of operation the isolating structure will deform allowing the mounting structure to contact the frame (12) and withstand forces on the cab rollover structure (18). This arrangement (26) of components provides an isolated mount which will not be overstressed during a vehicle rollover. <IMAGE>

Title: Controlled bending of an endotracheal tube
Inventor: WINLO LEO RONALD
IPC: A61M25/00
Filed: 1995-01-09
Abstract: Bending of an endotracheal tube 1 to aid insertion is effected by control of fluid pressure in one or more distally placed passageways 20 extending partially around the circumference of the tube 1. Said passageways 20 may be integral with or attached to the tube wall. Fluid (e.g. saline) pressure is controlled by a proximally located sack or bulb (not shown) connected to passage 24 which extends along the length of the tube 1 and is in fluid communication with said distal passageways 20. Manual pressure to the sack or bulb causes changes in fluid pressure within the passageways 20 causing them to expand or contract leading to bending of the distal end of the tube 1. Also disclosed are endotracheal tubes where bending is effected by a cord or flexible rod connecting the distal and proximal ends of the tube. A series of grooves cut into the wall of the tube provide a region of increased flexibility to allow localised bending to take place. <IMAGE>

Title: Apparatus for acquiring code phase lock in direct sequence spread spectrum systems
Inventor: HULBERT ANTHONY PETER
IPC: H04B1/707
Filed: 1995-02-16
Abstract: A received signal is applied via a frequency converter 4, which generates complex I Q baseband signals, to respective correlators comprising a multiplier 6 and an accumulator 12 in respect of the inphase signal and a multiplier 8 and an accumulator 14 in respect of the quadrature phase signal. The output of the correlators are subjected to a modulus squaring function which comprises multipliers 16, 18 and an adder 20. The output of the adder 20 is applied to a store 22, and the inputs and outputs to the store (which represent correlations spaced apart by one chip difference in code phase) are added together in an adder 24, the output of which is compared with a threshold value in a comparator 26. The correlators and store are controlled by a controller 28 which is arranged to control the setting and resetting of the accumulators 12 and 14. For a fixed interval of time a local code generator 10 is held constant, the output of which is applied to an input of the multiplier 6, 8, and at the start of the interval the accumulators 12, 14 are reset to zero and allowed to accumulate. At the end of the period the comparison is performed and thereafter the codes generated are shifted by one chip and the accumulators 12, 14 are set to zero and the output of the adder 20 is clocked into the storage means 22. This process is repeated until such time as the threshold value is exceeded as determined by the comparator 26.

Inventor: YOSHII KEIICHI
IPC: F28F13/04
Filed: 1996-04-18
Abstract: In a plate heat exchanger assembly, a tube element (2) is formed by a pair of symmetrical core plates (4). Each core plate includes a connecting portion (4a) for connecting the respective pair of core plates (4) at an upstream air side, an extending portion (4d) extending from the connecting portion (4a), a fin connecting portion (4e) for connecting the core plate to an adjacent corrugated fin (3), and an end portion (4f) which forms a gap with the corrugated fin (3). The arrangement closes the space between the tube element (2) and the adjacent corrugated fins (3) at the upstream air side of the refrigerant passage, so that the flow of air entering between the tube element (2) and the adjacent corrugated fins (3) can be substantially stopped. This prevents dust and dirt from contacting the tube element (2) so causing corrosion. In an alternative arrangement, the fin connecting portion (4e) may be bent in a U-shaped fashion back over the connecting portion (4a). The heat exchanger can be used as a refrigerant evaporator in a vehicle air-conditioning system.

Title: Multiple-clock controlled spatial light modulator
Inventor: WORCHESKY TERRANCE L
IPC: G02B26/08
Filed: 1996-12-06
Abstract: A SAR radar has an optical processor which uses an electrical-signal-to-light modulator. The modulator includes a tapped delay line (618) which may be either analog or digital, and the signals tapped from the delay line are applied to an array of temporary storage elements (624), which in the case of analog signals may he a capacitive sample-and-hold, or for digital signals may include store register. In order to improve the signal-to-noise ratio (SNR) by comparison with a processor using an acoustic modulator, the signals tapped from the delay line are sampled at a display sampling rate, which is very low by comparison with the signal sampling rate or the highest frequency of interest, and the sampled signals are held until the next following display rate pulse. The signals held in the temporary storage elements are applied to the modulator elements (612) so that the optical pattern remains fixed for relatively long periods of time during which the optical processing can integrate photons for improved SNR.
