20150238065 | STORED ENERGY GASKET-COMPRESSING LATCH WITH REDUCED ROTATIONAL FRICTION - An appliance latch provides a hook that may be energized against a spring force to receive a catch element which releases the hook to pull the catch element into engagement. A toggle arm may be used to hold the hook in the energized state before receipt of the catch element to provide for a sensitive and predictable release of the spring force with rotation of the hook. The hook may be mounted on a floating pivot both to accommodate the toggle arm operation and to permit re-engagement of the catch element with the hook in the event that the hook is released from its energized state without engagement of the catch element, for example, by inertial forces. | 08-27-2015 |
20150240527 | APPLIANCE LATCH WITH DOOR PRESENCE SENSING - A door locking mechanism for an appliance provides a bolt that may be moved by an actuator between an extended and retracted position. A bolt stop mechanism blocks movement of the bolt in retraction at one of two positions, depending on how the bolt was extended before the retraction. In this way the bolt automatically retracts when the door is not present because this causes extra extension of the bolt and an over-travel position need not be directly sensed reducing controller complexity or wiring. | 08-27-2015 |

20100301122 | NON-VOLATILE MEMORY CHARGE PUMP FOR RADIO FREQUENCY IDENTIFICATION (RFID) SYSTEM - A charge pump is incorporated into circuitry of an RFID tag. The charge pump takes advantage of an antenna voltage phase to eliminate the need for a charge pump clock generator. Placement of the charge pump in the RFID circuitry reduces the number of pump stages and eliminates drivers used in each pump stage. In some implementations, an RFID tag comprises antenna circuitry, including a tuned antenna, for receiving an RF signal. Voltage conversion circuitry in the RFID tag is coupled to the antenna circuitry and operable for converting a varying magnetic field produced in the antenna to a voltage source. A charge pump is coupled to output voltage signals of the antenna circuitry which provide the charge pump with a high starting reference voltage and a two phase pump clock. | 12-02-2010 |

20080256999 | APPLIANCE LATCH WITH POWER FAILURE UNLOCK - A lock for a washing machine or the like provides fast actuation through a solenoid driven bolt that remains stably in the locked position after power is no longer applied to the solenoid. The possibility of power failure preventing subsequent access to the washing machine is avoided through the use of a slower actuation time, thermal actuator storing sufficient energy to unlock the bolt after a time delay when power is lost. | 10-23-2008 |
20080264455 | HUMIDITY REDUCING EXHAUST DUCT FOR DISHWASHER - A vent system for a dishwasher provides a mixing chamber receiving high humidity air from a downdraft dishwasher vent system or the like and mixes this air with dry air before discharging it from the dishwasher to reduce the humidity of the discharged air moderating condensation problems | 10-30-2008 |
20100052338 | GASKET-COMPENSATING LATCH MECHANISM - A latch for an appliance or the like provides a floating bolt assembly spring biasing a door against a sealing gasket in different positions depending on gasket compliance. A lock provides a stop that may adjustably bridge a distance between the latch frame and the floating bolt assembly as the gasket ages thereby providing positive locking of the door over the life of the appliance. | 03-04-2010 |
20120175894 | APPLIANCE LOCK WITH MECHANICAL DOOR SENSOR - A locking latch for an appliance provides an improved three-wire interface that reduces the chance of malfunction if the door is forcibly opened when it is in the lock state and a bi-stabile actuator is used. In one embodiment, the door switch is positioned to disengage the major load of the washing machine when the doors open, regardless of the lock or unlock state. | 07-12-2012 |
20120186288 | ICE-HARVEST DRIVE MECHANISM WITH DUAL POSITION BAIL ARM - An ice-maker drive mechanism presents a housing having a frontward extending drive for an ice-harvester mechanism and left and right bail arm drive hubs. A bail arm that may drop into an ice bin collecting ice from the ice-maker to sense a height of ice cubes in a the ice bin may be attached to either of the left and right bail arm drive hubs providing a versatile ice-making mechanism that may be used in a variety of refrigerator designs. | 07-26-2012 |
20120312594 | LID LOCK WITH MAGNETIC ANTI-TAMPER FEATURE - A latch for a washing machine or other appliance provides two interengaging elements on a lid and housing each having a magnet oriented for mutual repulsion. Proper repulsion of the magnets is necessary to signal that the lid is properly closed such as may be used to determine if the appliance may be locked and safely operated, for example, in a clothes spinning mode. | 12-13-2012 |
20130008046 | APPLIANCE LATCH WITH IMPROVED DOOR RETENTION AT ELEVATED TEMPERATURES - A door latch for an appliance provides a U-shaped spring for engaging a strike having an expanded tip and passing between the arms of the U-shaped spring in a direction substantially perpendicular to the extent of those arms. Locking of the latch may be provided by collaring the distal ends of the arms to prevent their expansion once the strike is engaged. | 01-10-2013 |
20140170954 | DISHWASHER WITH SELF-SEALING VENT FAN - A vent fan for use with the dishwasher and providing a vent door covering the opening associated with a motorized fan employs a mechanical coupling between the fan motor and vent door to eliminate the need for a separate vent door actuator by using energy of the fan motor to accomplish the actuation. | 06-19-2014 |
20150240527 | APPLIANCE LATCH WITH DOOR PRESENCE SENSING - A door locking mechanism for an appliance provides a bolt that may be moved by an actuator between an extended and retracted position. A bolt stop mechanism blocks movement of the bolt in retraction at one of two positions, depending on how the bolt was extended before the retraction. In this way the bolt automatically retracts when the door is not present because this causes extra extension of the bolt and an over-travel position need not be directly sensed reducing controller complexity or wiring. | 08-27-2015 |

20140124688 | ROTARY ACTUATOR FOR ENERGY EFFICIENT ICE CUBE DISPENSER DOOR SYSTEM - A rotary actuator suitable for use in a refrigerator ice-dispensing door provides a rotating shaft driven by a DC permanent magnet motor through a gear train and subject to a returning force of an internal spring. The gear train communicates with a switch to reduce current to the motor when a limit of travel is reached and a shunting path is provided around the motor to produce generative braking when power is removed from the motor and the actuator rotates backward to its initial position. | 05-08-2014 |
