Publication number: 20120160525Abstract: A closed-loop system employs video analytic outputs in a feedback loop to control the operation of a video-based fire detection system. In particular, video data captured by a video detector is analyzed by a video analytic system to generate outputs identifying regions indicative of fire. These outputs are employed as feedback in a closed-loop control system to orient the camera such that field of the view of the camera is modified to improve the ability of the video analytic system to verify or confirm the presence of fire within a region identified as indicative of fire. In addition, video analytic system may generate outputs identifying the delivery location of a fire suppressant. These outputs are employed as feedback in a closed-loop control system to orient the delivery of suppressant to extinguish the fire.Type: ApplicationFiled: December 22, 2010Publication date: June 28, 2012Applicant: UTC FIRE AND SECURITY CORPORATIONInventors: Alan Matthew Finn, Pei-Yuan Peng, Rodrigo E.

Patent number: 8155399Abstract: There is provided a discriminative framework for image alignment. Image alignment is generally the process of moving and deforming a template to minimize the distance between the template and an image. There are essentially three elements to image alignment, namely template representation, distance metric, and optimization method. For template representation, given a face dataset with ground truth landmarks, a boosting-based classifier is trained that is able to learn the decision boundary between two classes—the warped images from ground truth landmarks (e.g., positive class) and those from perturbed landmarks (e.g., negative class). A set of trained weak classifiers based on Haar-like rectangular features determines a boosted appearance model. A distance metric is a score from the strong classifier, and image alignment is the process of optimizing (e.g., maximizing) the classification score.Type: GrantFiled: March 26, 2008Date of Patent: April 10, 2012Assignee: UTC Fire & Security CorporationInventors: Xiaoming Liu, Peter Henry Tu, Frederick Wilson Wheeler

Publication number: 20120079859Abstract: 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.Type: ApplicationFiled: June 8, 2009Publication date: April 5, 2012Applicant: UTC FIRE & SECURITY CORPORATIONInventors: Vijaya Ramaraju Lakamraju, Jean Yamanis, Ulf J.

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.Type: ApplicationFiled: April 16, 2009Publication date: February 2, 2012Applicant: UTC FIRE & SECURITY CORPORATIONInventors: Vijaya Ramaraju Lakamraju, Ulf J.

Publication number: 20120025948Abstract: 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.Type: ApplicationFiled: April 6, 2009Publication date: February 2, 2012Applicant: UTC FIRE AND SECURITY CORPORATIONInventors: Vijaya R.

Publication number: 20120008832Abstract: A video-based object recognition system and method provides selective, local enhancement of image data for improved object-based recognition. A frame of video data is analyzed to detect objects to receive further analysis, these local portions of the frame being referred to as a region of interest (ROI). A video quality metric (VQM) value is calculated locally for each ROI to assess the quality of the ROI. Based on the VQM value calculated with respect to the ROI, a particular video quality enhancement (VQE) function is selected and applied to the ROI to cure deficiencies in the quality of the ROI. Based on the enhanced ROI, objects within the defined region can be accurately identified.Type: ApplicationFiled: March 17, 2009Publication date: January 12, 2012Applicant: UTC FIRE AND SECURITY CORPORATIONInventors: Hongcheng Wang, Zhen Jia, Lei Sun

Publication number: 20110291428Abstract: 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.Type: ApplicationFiled: February 20, 2009Publication date: December 1, 2011Applicant: UTC FIRE & SECURITY CORPORATIONInventors: John M.

Publication number: 20110259617Abstract: 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.Type: ApplicationFiled: December 18, 2008Publication date: October 27, 2011Applicant: UTC FIRE & SECURITY CORPORATIONInventors: Muhidin Lelic, Giuliano Amantini, May L.
