Title: A speed controller for a battery powered vehicle
Inventor: YAMAWAKI HAJIME
IPC: B62M7/02
Filed: 2001-01-25
Abstract: A human powered vehicle eg. a bicycle with a battery powered assisting drive is characterised by a speed controller 73. In an embodiment said speed controller detects pulses via a pulse detecting circuit 81 generated by the rotation of one the vehicles wheels. An arithmetic circuit 82 determines if a period of acceleration is occurring eg. during pedalling of the vehicle. If acceleration occurs the maximum speed attained is saved in a memory and a signal proportional to this speed is passed to motor 3 to maintain the vehicle at this speed when the period of acceleration is completed. If subsequent periods of acceleration occur the previous speed stored in the memory is overwritten by the new maximum speed obtained. On application of the brake the stored speed is erased and power to the motor is cut to preserve the life of the batteries. A 'dead mans' switch may also be included that detects the weight of the rider. Power is cut if the switch is not made i.e no rider is present or if the rider exceeds a predetermined weight.

Title: Calibration rod and testing apparatus for magnetic rolls
Inventor: FIESELER WAYNE GERARD
IPC: G01B7/24
Filed: 2001-03-23
Abstract: A calibration rod (1) with grooved track (2) and a testing apparatus (17) for magnetic rolls that produces an accurate homing location and probe-to-probe reference for repeated test verification at many testing locations. The grooved track calibration rod can be transported to different equipment to verify that equipment is performing similarly, has improved accuracy, has temperature compensation, uses a circumferential drive movement from one end of a roll magnet and verifies angular position from the other end, eliminates the possibility of angular inaccuracy from twisting of the part being measured during clamping and provides for improved accuracy of several degrees. A high order polynomial curve fit of the data is used to determine the true value of the Gauss level being measured during 360 degree revolution. The apparatus takes measurements to accurately measure magnetic differences which define differences in probe operation. The value of other probes will be matched (multiplied by a percentage) to a first master reference probe. The apparatus eliminates twist, which can affect pole location accuracy by several degrees.

Title: Virtual studio system
Inventor: THOMAS GRAHAM
IPC: H04N5/272
Filed: 2002-03-15
Abstract: A system is disclosed which enables feedback to be provided to two participants in a virtual studio. An image is rendered from the perspective of the relevant participant and projected so as to be visible to the participant but keyed out of the camera image of the studio by a keying process. The actor is aided by providing an indication of the presence of objects in the background image which is to be keyed with the image of himself. To achieve this, an image from the actors viewpoint is projected into the studio environment so that the actor can see where the virtual objects are. A claimed embodiment details how a portion of the projected image may be masked based on the presence of objects in the studio so that projection onto these objects is reduced. Another embodiment provides for a situation where different images are projected for different actors wherein these images may be multiplexed. The actors are the provided with de-multiplexing means in order to see the image intended for them to view.

Title: A method for preventing contamination of a dielectric
Inventor: KARTHIKEYAN SABRAMANIAN
IPC: H01L23/52
Filed: 2003-08-14
Abstract: A process for preventing interconnect metal diffusion into the surrounding dielectric material. Prior to the formation of a metal interconnect in an opening of a dielectric region, the underlying metal surface is cleaned, during which metal can be deposited on the sidewalls of the opening. This metal can diffuse into the dielectric and cause leakage currents. To prevent deposition of the metal onto the sidewalls a barrier layer is deposited into the opening and sputtered onto the sidewalls before the metal surface cleaning step.
