20110209507 | SEMI-ACTIVE ELECTRORHEOLOGICAL FLUID CLUTCH FOR ELECTRONIC DOOR LOCK - A clutch for an electronic door lock includes a first shaft, a second shaft, a spring, a rheological fluid, and a plunger. The second shaft has an aperture therein and is axially co-aligned with the first shaft and is rotatably mounted adjacent the rotatable first shaft. The spring is disposed in the aperture in the second shaft. The rheological fluid is held within the aperture and is capable of changing viscosities in response to the application of an electrical current across the fluid. The plunger is biased by the spring into selective coupling engagement with the first shaft and is capable of selective motion into the aperture in response to contact by a camming surface of the first shaft due to relative rotation of the first shaft with respect to the second shaft. | 09-01-2011 |
20110210564 | BI-STABLE ACTUATOR FOR ELECTRONIC LOCK - An actuator for an electronic door lock includes a stationary first magnet assembly, a beam, and a second magnet assembly. The first magnet includes at least one magnet stationarily positioned within the electronic door lock. The beam is movable relative to the first magnet assembly to a first position and a second position. The second magnet assembly is connected to the beam and is configured to be magnetically repulsed away from the first magnet assembly. The repulsion of the second magnet assembly maintains the beam in either the first or second position until the beam is selectively actuated therefrom. | 09-01-2011 |
20110291428 | LOW ENERGY CLUTCH FOR ELECTRONIC DOOR LOCK - A clutch for an electronic door lock includes a primary mover, a pivotal pawl, a first shaft, and a second shaft. The second shaft is axially co-aligned with the first shaft and is rotatably mounted adjacent the rotatable first shaft. The primary mover is selectively actuatable to engage the pawl such that rotation of the first shaft relative to the second shaft by a user pivots the pawl into coupling engagement between the first shaft and the second shaft. | 12-01-2011 |
20120024155 | BATTERY FIRE PREVENTION DEVICE - A battery fire prevention device includes a lithium battery, a container, and a porous material. The container houses the lithium battery and has an outwardly interfacing wall with an aperture which extends therethrough to vent outgassed battery constituents generally away therefrom. The porous material is disposed within the container between the aperture and the battery. The porous material is capable of trapping lithium particulates outgassed from the lithium battery within the container. | 02-02-2012 |
20120025948 | POWER MANAGEMENT CIRCUITRY FOR ELECTRONIC DOOR LOCKS - A power management circuit decreases power consumption in an electronic door lock. The power management circuit includes an ON/OFF circuit, a load switch circuit and a electronic door lock circuit. The ON/OFF circuit generates an initial enable signal in response to a detected keycard that places the load switch circuit in an enabled state. When enabled, the load switch circuit provides dc power to the electronic door lock circuit that allows the electronic door lock circuit to receive identification input from the detected keycard and determine whether an output should be generated to actuate the door lock mechanism. Having completed the keycard detection operation, the electronic door lock circuit generates a self turn-off signal that is provided as feedback to the ON/OFF circuit to disable the load switch circuit. When disabled, the load switch circuit prevents any power from being provided to the electronic door lock circuit and thereby conserves energy otherwise consumed by the electronic door lock in times between activations. | 02-02-2012 |
20120079859 | BATTERY FIRE PREVENTION VIA THERMAL MANAGEMENT - An assembly for preventing a fire resulting from the outgassing of a lithium battery in an electronic door lock includes a lithium battery, a circuit board, and a thermal insulation. The lithium battery and circuit board are housed within the electronic door lock. The thermal insulation is arranged between a door interfacing side of the electronic door lock and either or both of the circuit board and lithium battery. Another thermal management technique for preventing fire resulting from the outgassing of a lithium battery in an electronic door lock is achieved by using a battery cover that is selectively movable away from the circuit board or ignition source in response to temperature rise to ensure the lithium battery does not reach a critical temperature that may cause outgassing in close proximity to the ignition source. | 04-05-2012 |
20130274388 | METHOD OF MAKING A CORD AND POLYMER JACKET ASSEMBLY HAVING A FLAME RETARDANT IN THE POLYMER JACKET MATERIAL - An illustrative method of making an elevator load bearing member having at least one elongated tension member at least partially covered by a jacket includes mixing a flame retardant with a polymer material. The flame retardant is selected from a group consisting of (i) a halogen-free melamine based intumescent comprising melamine cyanurate, melamine-phosphate, melamine pyrophosphate or melamine polyphosphate in an amount up to about 20% by weight of the thermoplastic polymer or (ii) a filled polymer having a nanoscale filler chemically bonded to a matrix phase. Applying the mixed flame retardant and polymer material to the tension member forms a jacket of a desired shape. | 10-17-2013 |
20140015168 | TENSION MEMBER AND POLYMER JACKET ASSEMBLY INCLUDING A GEOMETRY STABILIZER IN THE JACKET - An exemplary assembly includes at least one elongated tension member. A jacket covers at least some of the tension member. The polymer jacket comprises a polymer material including a melamine based geometry stabilizer that facilitates maintaining the jacket material near the tension member if the assembly is subjected to a high temperature condition. | 01-16-2014 |
