Title: Imaging system
Inventor: ROBINSON CHRISTOPHER PAUL
IPC: H04N5/349
Filed: 1988-04-13
Abstract: An imaging system, which improves the optical revolution and reduces optical alias of a solid state imager comprises a lens and a modulating element, which alters incident radiation in such a manner as to displace the image by fractions of a pixel between adjacent fields by either mechanically shifting the elements or by electro-optic variations of refractive index. A processing system is also provided, in which alternate fields are interlaced and output to a monitor. The modulator is arranged in a demountable manner, so that it can be "bolted on" as an additional attachment to a standard camera. The processing means is attached via the original CCD output terminal.

Patent GB-2216298-A (GB)
Title: Control of an automatic welding machine
Inventor: TSUJII GEN
IPC: B23K11/25
Filed: 1989-02-23
Abstract: The respective movements of a pair of welding gun arms (31, 32) are detected by a pair of distance sensors (61, 62), which each output a signal dependent on the position or rate of change of position of the gun arms (31, 32). This signal is used to determine whether each gun arm has started to move towards its open position when the welding gun is operated to open after each welding operation. When sufficient movement of each gun arm (31, 32) towards its opened position has been registered by the distance sensors (61,62) it is assumed that neither of the electrode tips (3a) in the gun arms (31, 32) have become spot welded to the workpiece during the welding operation and a robot moves the welding gun to a new welding position. As the gun arms (31, 32) do not have to open fully before the robot moves the welding gun on, time is saved between welding operations.

Patent GB-2220456-A (GB)
Title: Electric cable grommets
Inventor: PATTON STUART
IPC: H02G3/08
Filed: 1989-07-06
Abstract: The deformation of grommets by compression for fitting into holes to protect electrical wires is not always easy and the deformable nature can give rise to pulling out. In order to elevate such problems a grommet 10, which is split, can be flexed between larger and smaller effective diameters so that the material is effectively not reliant on deformation of its thickness. The preferred splitting provides staggered ends which have overlying circumferential portions 16A, 16B. One side of the grommet has a chamfer 24 leading to a groove 18.   <IMAGE>

Title: Smoke density monitor system
Inventor: SUZUKI TAKASHI
IPC: G08B17/103
Filed: 1990-12-18
Abstract: A smoke density monitoring system uses an array of light sources 2 and light detectors 3 to divide a space to be monitored two-dimensionally into a plurality of notional subspaces. The light sources and detectors create a number of intersecting light paths 4 passing through a plurality of arbitrary subspaces. The detectors assess the transmittance of light transmitted along each path; and the output from the detectors is converted into a digital signal. A CPU 10 calculates the relative transmittance of each subspace using a mathematical method in which the measured transmittances of the paths are placed into matrices and calculations are performed using the matrices and previously stored data. The smoke density for each of the subspaces is then determined on the basis of the transmittance through each subspace. <IMAGE>

Patent GB-2249922-A (GB)
Title: Dynamic channel allocation method
Inventor: TOMABECHI AKITAKA
IPC: H04W72/08
Filed: 1991-07-22
Abstract: In a multichannel time division multiple access (TDMA) mobile radio communication system prior to a collision between a time slot used in a base station or mobile station and a time slot employed by another base station or mobile station, a free channel is selected. This is effected by a particular station receiving a signal from a different station using a different time slot at the same frequency, with independent synchronization (and possibly with a different time slot timing) and estimating the chance of a collision between the time slots, and then depending on the estimate conducting a transition 306 to a detected free channel. This collision avoidance enables multichannel TDMA to be applied to existing mobile telephone systems operating in an asynchronous manner. <IMAGE>

Title: Gear-changing device for multi-speed hubs has pawl clutches maintained in engaged position
Inventor: BERGLES EDUARD
IPC: B62M11/18
Filed: 1993-08-31
Abstract: The invention relates to a gear-changing device between two ratchet planes in a multi-speed hub, which can also be engaged and disengaged under load. This is achieved by driving pawls (5, 6) arranged one over the other and held forcibly in a following engagement, of which the inclination of the tooth engagement is chosen in such a way that the driving pawls are shifted out of engagement under load. A control disc (7) can be displaced to a position below the driving pawls whereby these are alternately held and locked in their associated ratchets. The control disc is carried along at the driving speed by means of a follower disc (4b) in the pawl carrier (4) and has in relation to the driving pawls a backwardly directed free play or backlash which is necessary in order to employ the initial angular movement on backward movement on braking for releasing the forcibly held driving pawls. <IMAGE>

Title: Anti-lock control method for vehicle
Inventor: SUTO SHINJI
IPC: B60T8/62
Filed: 1993-11-04
Abstract: An anti-lock control method for a vehicle includes the steps of: calculating an operation control quantity (PY) on the basis of a reference braking pressure (PBR), and controlling the operation of an actuator (23FL) to adjust the braking force of a wheel brake in accordance with the operation control quantity (PY), to reduce the braking force. In this method, the braking pressure at the start of an anti-lock control when a wheel is about to be locked during braking is corrected in accordance with the degree of wheel locking tendency (e.g. wheel acceleration  alpha ) to provide the reference braking pressure (PBR). Thus, it is possible to determine the braking pressure with good accuracy, leading to enhanced accuracy of the anti-lock control. <IMAGE>
