Patent number: 7336044Abstract: A DC motor control circuit includes a pair of substantially identical unipolar control circuits. Each of the unipolar control circuits are connected between a respective current source and a current input to the motor. Each of the unipolar control circuits includes a solid state switch located between a motor current input and the source of direct current. The degree to which the solid state switch allows current to flow to the motor is controlled by an input bias signal to the switch. Current limiting for adjusting the input bias signal according to the current flowing through the motor is provided in one way of controlling the motor movement.Type: GrantFiled: September 20, 2000Date of Patent: February 26, 2008Assignee: Visiocorp Patents S.a.r.l.Inventors: Andrew Churchett, Donald Kay

Patent number: 7282881Abstract: A circuit and method of reducing the occurrence of overheating of a power fold vehicle mirror. The circuit controls the operation of the power fold mirror such that when a portion of the circuit reaches or exceeds a predetermined temperature threshold, the vehicle mirror is prevented from at least folding in. In practice, the vehicle mirror will be allowed to fold out even when the predetermined temperature threshold has been reached or exceeded, to allow the vehicle door to be opened and the car to be driven. The vehicle mirror may be allowed to be folded in when the temperature of the circuit falls to or below a second predetermined temperature threshold.Type: GrantFiled: March 25, 2004Date of Patent: October 16, 2007Assignee: Schefenacker Vision Systems Australia Pty Ltd.Inventor: Donald Kay

Patent number: 4905698Abstract: A method and apparatus (10) for determining accurately the location of the tip (14) of a catheter (16) inside biological tissue is disclosed including a locator (34) having a coil (38) wound axially on a core (36) and a detector (12) in the form of a coil (28) wound on a core (24) removably positionable within catheter (16) adjacent the tip (14). A controller (20) generates AC current to coil (38) to produce an electromagnetic field and compares it with the output voltage developed in coil ( b 28) when the locator (34) comes within close physical proximity to detecetor (12). Locator (34) includes an amber LED indicator (42) which is energized when the locator (34) is behind the detector (12) and the monitored output voltage is in phase with the generated alternating current and includes a red LED indicator (44) which is energized when the locator (34) is beyond the detector (12) and the monitored output voltage is 180.degree. out of phase with the generated alternating current.Type: GrantFiled: September 13, 1988Date of Patent: March 6, 1990Assignee: Pharmacia Deltec Inc.Inventors: Clair L.

Patent number: 4743231Abstract: A needle or cannula set especially adapted to access an implanted drug delivery portal includes a rigid base having a flat undersurface and a low profile. The base supports one end of a needle so that the needle projects from the base perpendicular to the base undersurface. One end of a flexible tube is secured to the base in fluid communication with the needle and the opposite end of the tube is terminated by a connector. A complaint pad is mounted to the base undersurface to assure proper seating of the base against the skin of the patient when the needle unit is inserted in the patient. The set also includes a handle which releasably connects to the base to facilitate inserting the needle unit into and withdrawing it from the patient and an adhesive dressing which is arranged to drape over the base with its edge margin extending all around the base for anchoring the needle unit to the patient and for providing an occlusive seal all around the puncture site.Type: GrantFiled: July 6, 1987Date of Patent: May 10, 1988Assignee: Pharmacia NutechInventors: Donald A.
