IPC: A63B23/12
Filed: 1995-09-12
Abstract: The present invention discloses an exercise apparatus which includes a gripping or handle assembly which is grasped at each of its ends by a user's hands. The handle assembly is rotatably mounted on a support having a configuration selected so that when the ends of the handle assembly are grasped by the user, the user is in a position with his hands positioned above his shoulders. The handle is then rotated by the user pulling on one end of the assembly and then the other end, to pivot the handle assembly about a pivot point and stretch the various upper body muscles.

Title: Voltage Regulators
Inventor: HARMAN STEPHEN G
IPC: G06F3/00
Filed: 1994-06-15
Abstract: A voltage regulator for an electronic circuit card includes a FLT (26) with a source supplied via an input LC filter (28, 38) with a voltage to be regulated, a drain for delivering a regulated output voltage via a current-sensing resistor (32) and an output LC circuit (34, 40), and a gate which is supplied with a current drive from a linear transconductance amplifier (54) having a differential input (+,-)responsive to the regulated output voltage relative to a reference voltage. The regulator provides large bandwidth low voltage drop regulation without requiring higher voltage supply for the gate of the FET. A current limiting circuit (82, 84) reduces the current drive in response to excessive current through the current-sensing resistor, and a turn-on control circuit (68) reduces the current drive to provide a controlled turn-on for hot insertion of the card into electronic equipment.

Patent CA-2173083-A1 (CA)
Title: A printer for printing on a continuous print medium
Inventor: GREEN MICHAEL CAMERON
IPC: B41J17/04
Filed: 1996-03-29
Abstract: A thermal printer for printing on a continuous print medium by ink transfer from a thermal print ribbon has a print head which is pivotally mounted and which is driven in an oscillatory nodding motion by means of a stepper motor so as repeatedly to bring a linear array of energisable printing elements to bear against a platen roller. Both the element array and the platen extend transversely to respective paths of travel of the print medium and the ribbon. The print medium is fed through the printer from an inlet region, between the platen and print head, and thence to an outlet region. The instantaneous rate of travel of the print medium past the print head is substantially the same as the rate of feed of print medium to the printer. Typically this rate is of the order of 250 to 400 mm per second. The ribbon also travels between the print head and the platen, overlying the print medium and is driven in such a manner that it travels at the same rate as the print medium during each printing operation. This is achieved by driving the ribbon with a motor the speed of which is controlled according to the sensed speed of travel of the print medium, e.g. by coupling the motor to processing circuitry which takes an input signal from a shaft encoder associated with the platen roller. Alternatively, the ribbon may be driven by frictional contact with the print medium. These methods of driving the ribbon have the advantage that the ribbon speed can be varied to take account of different print medium speeds, e.g. due to the requirements of differing packaging processes, and also in response to transient variations in print medium speed during each printing operation.

Abstract: An outer layer forming material is injected into a cavity in a mold and then, a core forming material is injected, whereby the core forming material is allowed to flow into the outer layer forming material existing in the cavity, and both the materials are allowed to flow within the cavity.  The cavity has a main area for forming a bumper main portion, and side areas for forming bumper sides.  A relation, d1> d2 is established between a distance d1 determining a bumper thickness of a first section for forming an upper portion of the bumper main portion and a distance d2 determining a bumper thickness of a second section for forming a lower portion of the bumper main portion.  A relation, d3>d1 is established between a distance d3 determining a bumper thickness of the side areas and the distance d1.  A film gate opens into the first section.  Thus, in the main area and the side areas, the times required for the filling of the outer layer forming material to be completed are substantially equal to each other.

Abstract: The invention concerns a DNA sequence for the genetic therapy of tumours. The essential components of the DNA sequence consist of an activator sequence, a promoter module and a gene for the active substance. The activator sequence is activated cell-specifically in proliferating endothelium cells or cells neighbouring these endothelium cells. The promoter module regulates this activation specifically according to the cell cycle. The active substance is an angiogenesis inhibitor or a cytostatic or cytotoxic molecule. The DNA sequence is introduced into a viral or non-viral vector, supplemented by a ligand having affinity for the activated endothelium cell.

Title: Method for measuring the conservation of stereophonic audio signals and method for identifying jointly coded stereophonic audio signals
Inventor: HERRE JURGEN
IPC: H04S1/00
Filed: 1995-10-11
Abstract: The conservation of stereophonic audio signal properties is measured by using a stereophonic signal as reference signal and creating a signal for testing by processing the stereophonic signal, e.g. by coding and subsequently decoding it.      Both signals are transformed into the frequency domain to create representative spectral data for the respective subbands. Signal quantities are determined for each subband both of the reference signal and also of the signal for testing on the basis of the spectral data of the channels of the reference signal or of the signal for testing. From the comparison of the signal quantities belonging to the same subband, conclusions can be drawn concerning the conservation of the stereophonic audio signal properties for the processing or coding technique being used.

Patent CA-2204687-A1 (CA)
Inventor: VAN BEEK GARY
IPC: G06V10/147
Filed: 1997-05-07
Abstract: An optical system for an optical character reader in which a camera, such as a TV camera, reads an image field in a document, includes at least one pair of mirrors which shift half of the image both laterally and vertically to convert a relatively long image, for example with a length to height aspect ratio of 1.5:8, into a rectangular image with a much lower aspect ratio, for example 3:4. Preferably two pairs of mirrors are used, so that the image light path for both parts of the image field is the same length. This optical system reshapes the image field from one having an aspect ratio which does not match the 3:4 aspect ratio of most cameras, such as camcorders, TV cameras, security and surveillance cameras and the like, into one that does, thus significantly simplifying the optical character reader, and lowering its cost.
