  • Patent number: 11292512
    Abstract: A method of operating an electric power assisted steering system of the kind in which an electric motor applies an assistance torque to a part of the steering system as a function of an assistance torque signal, the assistance torque reducing the force required by the driver to turn a steering wheel, comprises during normal operation generating an assistance torque signal that is dependent on the torque applied by the driver, and during a fault operation in which the torque applied by the driver is not reliably known to the system generating an assistance torque signal that is derived from a first term that has a value that varies as a function of the angular position of the steering relative to a changeable datum, the angular position of the changeable datum being updated in the event that the direction of rotation of the steering changes.

  • Patent number: 10370915
    Abstract: A gauge hanger 10 and a setting tool 12 are disclosed. The setting tool 12 includes an electro-mechanical impact driver 26 and a drive shaft 28 which extends out of an outer casing 12. The gauge hanger 10 comprises a nut 32 which can be engaged by the drive shaft 28. When the nut 32 is rotated it can draw a threaded mandrel 36 upwardly in a wellbore. This causes the grippers 40 in a linkage assembly to be driven radially outwardly so that they can grip the sides of the wellbore. A pin 52 is designed to shear once the grippers have engaged with the sides of the wellbore so that the setting tool 12 can be lifted clear.

  • Patent number: 7662004
    Abstract: A pair of foils are pivotably coupled to a nacelle. The nacelle is pivotably coupled to a mast extending down from to a frame and below a water surface. A push rod oscillates, causing the nacelle to experience a heaving motion, in turn causing the foils to flap up and down. The push rod is driven by a power plant such as a human rider. Angles of attack for the foils are actively controlled to optimize lift and propulsion forces provided by the foils to cause the water craft to move over the water. A steering fin is also provided for heading control of the water craft. A control system for separate angles of attack for the foil sends appropriate information to servo motors which cause the foils to rotate relative to the nacelle to achieve optimal angles of attack relative to the particular position of the nacelle at any given moment.

  • Patent number: 7468652
    Abstract: A voice acquisition system for a vehicle includes an interior rearview mirror assembly attached at an inner portion of the vehicle. The mirror assembly preferably includes at least one microphone for receiving audio signals within a cabin of the vehicle and generating an output signal indicative of these audio signals, the at least one microphone providing sound capture for at least one of a hands free cell phone system, an audio recording system and an emergency communication system. The system includes a control that receives the output signal from the at least one microphone and distinguishes the presence of vocal signals from non-vocal signals. The system preferably comprises a learning mode whereby a vocal characteristic of a particular driver or occupant of the vehicle is learnt so that the ratio of vocal signals emanating from that particular driver or occupant to non-vocal noise signals received by the system is enhanced.

  • Patent number: 6977619
    Abstract: A door handle assembly for a vehicle includes a handle portion and an antenna positioned within the handle portion. The handle portion is movable or actuatable to open the door of the vehicle. The antenna receives a signal from a remote signaling device and communicates a signal to an accessory or system of the vehicle, such as a door locking/unlocking system of the vehicle, a lighting system of the vehicle, an ignition system of the vehicle, and/or the like. The antenna may function to receive the signal and automatically communicate a signal to the accessory or system of the vehicle in response to a remote signaling device approaching the door handle assembly. The antenna is preferably positioned within a cavity of the door handle portion and, more preferably, the handle portion is molded at least substantially around the antenna.
