| 20120096265 | Method and apparatus for communicating information between a security panel and a security server - A security panel includes a processor, memory, and a network interface having a unique MAC address, and is configured to communicate over a network with a server. A method for registering the security panel with the server includes contacting the server utilizing a network address stored in the memory. A dealer ID, a line number, and a unique account number is sent to the server. The dealer ID, the line number, and the unique account number are stored in the memory. An encryption key is received for encryption of additional communication between the security panel and the server. The unique MAC address is sent to the server in an encrypted session to verify the security panel to the server. | 04-19-2012 |
| 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 |
| 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 |
| 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 |
| 20110260081 | DISCHARGE FLOW CONTROL VALVE - A self-regulating valve controls the flow of high pressure gas discharging from a gas cylinder in a fire suppression system in response to a detection of a fire within a protected space by a two-step process which reduces the pressure rise within the protected space upon release of the fire suppression gas into the protected space. | 10-27-2011 |
| 20110259617 | ATOMIZING NOZZLE FOR A FIRE SUPPRESSION SYSTEM - A nozzle for a fire suppression system has a bonnet and a deflector base. An inlet port extends through the bonnet along the axis of symmetry of the bonnet. The inlet port receives an outlet end of a fire suppression delivery pipe to mount the bonnet to the pipe. The bonnet has a frustoconical surface which extends radially outward and downward from the inlet port. The deflector base is secured to and co-axially aligned with the bonnet at a predetermined distance to create a flow passageway therebetween. The flow passageway imparts a down angle to a suppressant flow discharging from the nozzle to better disperse the suppressant within the fire zone. A discharge port at the circumferential edge of the bonnet and deflector base constricts the suppressant flow to atomize the droplets of liquid suppressant discharged into the fire zone. | 10-27-2011 |
| 20110223548 | OXYGEN TRIM CONTROLLER TUNING DURING COMBUSTION SYSTEM COMMISSIONING - A method is provided for tuning an oxygen trim controller during the commissioning of a combustion control system for controlling operation of a boiler combustion system, rather than tuning the oxygen trim controller after the commissioning process has been completed. | 09-15-2011 |
| 20110212404 | AUTOMATED SETUP PROCESS FOR METERED COMBUSTION CONTROL SYSTEMS - A method is provided for the automated setup of a metered combustion control system for controlling operation of a boiler combustion system. The automated setup process includes both commissioning and controller tuning, rather than tuning the carbon monoxide and/or oxygen trim controller after the commissioning process has been completed. The oxygen trim controller or the carbon monoxide trim controller is used to identify the air/fuel ratio. | 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 |
| 20110180276 | FIRE SUPPRESSION SYSTEM WITH IMPROVED TWO-PHASE FLOW DISTRIBUTION - A two-phase liquid/inert gas flow inerting fire suppression system is provided having improved liquid fire suppressant distribution within the inert gas flow. The system includes a flow distribution network having a first pipe interconnected with a second pipe at a flow splitting tee. A liquid flow redistribution device is disposed in the first pipe upstream with respect to fluid flow of the flow splitting tee. | 07-28-2011 |
| 20110175378 | ADJUSTABLE DOOR STRIKE FOR LATCH AND DEADBOLT - An adjustable door strike includes a mounting bracket ( | 07-21-2011 |
| 20100294518 | HYBRID INERT GAS FIRE SUPPRESSION SYSTEM - A hybrid fire suppression system includes a supply of pressurized inert gas, a pipe network connected in inert gas flow communication to the inert gas supply, a first inert gas nozzle, a second inert gas nozzle, and a water storage cartridge having an interior volume defining a water reservoir storing a limited amount of water. The water reservoir communicates with the second inert gas spray nozzle. The first inert gas nozzle connects with the first terminus for introducing a flooding flow of inert gas only into a first protected space. The second inert gas nozzle connects with the second terminus for introducing a flooding flow of inert gas and the limited amount of water from the water reservoir into the second protected space. | 11-25-2010 |
| 20100230412 | LIFE SAFETY MOUTING SYSTEM AND METHOD - A life safety assembly includes an attachment stud configured to attach to a surface, and a life safety device that is mountable on the attachment stud. The life safety device has a receptacle configured to receive and interlock with the attachment stud to mount the life safety device with respect to the surface. | 09-16-2010 |
| 20100073477 | SYSTEM AND METHOD FOR VIDEO DETECTION OF SMOKE AND FLAME - A method for detecting flame and smoke using spatial analysis of video input ( | 03-25-2010 |
| 20100034420 | SYSTEM AND METHOD FOR VIDEO BASED FIRE DETECTION - A method for recognizing fire using block-wise processing of video input provided by a video detector. Video input is divided into a plurality of frames ( | 02-11-2010 |
