Publication number: 20090173186Abstract: A declutching mechanism includes a chassis, a first gear rotatable relative to the chassis about a first gear axis fixed relative to the chassis, and a second gear selectively engageable with the first gear. The declutching mechanism includes an eccentric arrangement having a first shaft with a first shaft axis and a second shaft with a second shaft axis offset from the first shaft axis. The first shaft is non-rotatably fixed to the second shaft and selectively rotatably mounted in the chassis. The second gear is rotatably mounted on the second shaft. A holding feature selectively holds the eccentric arrangement in a first position. With the eccentric arrangement being held in the first position by the holding feature, the first gear and the second gear are in meshing engagement. With the eccentric arrangement being released by the holding feature, gear separating forces cause the eccentric arrangement to rotate about the first axis to a second position, thereby disengaging the first gear and the second gear.Type: ApplicationFiled: December 18, 2008Publication date: July 9, 2009Inventors: Nigel V.

Publication number: 20090174268Abstract: A mechanism includes a movable member and a reluctance motor having an armature, a coil and two pole pieces, the armature being operably coupled to the movable member. The mechanism also has a first condition in which the reluctance motor is powered and the moveable member engages the pole pieces to magnetically hold the moveable member in a first position and a second condition in which the reluctance motor is unpowered and the moveable member is in a second position disengaged from the pole pieces. With the mechanism in the second position, powering of the reluctance motor causes the armature to rotate to drive the moveable member to the first position.Type: ApplicationFiled: December 18, 2008Publication date: July 9, 2009Inventors: Nigel V.

Patent number: 7170253Abstract: Latch control methods and systems are disclosed, including a latch that receives power from a motor associated with a latch. A sensor can be provided for monitoring the current consumption of the motor. A microcontroller can control the latch and/or the motor, based on the current consumption data received from the sensor concerning the current consumption of the motor. Monitoring of the current waveform of the motor therefore provides speed and direction feedback data for control of the latch. Additionally, a microprocessor can process instructions for controlling the interaction of the motor, the latch, the sensor and/or the microcontroller. Such a current monitoring control system is made possible by variation in current consumption of the motor during rotation as a result of commutation, which can be interrogated by measuring the voltage drop across the motor or a shunt resistor, or through the use of other current sensors, such as, for example, a Hall-effect type current sensor.Type: GrantFiled: September 14, 2004Date of Patent: January 30, 2007Assignee: Honeywell International Inc.Inventors: Nigel V.
