20150041158 | FIRE SAFETY CONTROL SYSTEM - A fire safety control system includes a storage container with an agent; a valve on the storage container for releasing the agent; a control head on the valve for actuating the valve; and a connection sensor on the control head for sensing whether the control head is connected to the valve and for producing a connection status signal. | 02-12-2015 |
20130097507 | FILMSTRIP INTERFACE FOR SEARCHING VIDEO - An interface for searching and playing recorded video comprises a filmstrip snapshot sequence, a selection window, a first input device, a second input device, and a third input device. The filmstrip snapshot sequence comprises chronologically ordered snapshots associated with video segments of the recorded video. The snapshots are taken at regular intervals that may be equal to the length of the video segments. The selection window highlights consecutive snapshots from the filmstrip snapshot sequence. The first input device advances the filmstrip snapshot sequence, causing the selection window to highlight a chronologically later set of snapshots. The second input device zooms in on the filmstrip snapshot sequence as a function of time, causing a new set of snapshots to be retrieved at a smaller regular interval. The third input device causes the video segments associated with the highlighted snapshots to be played. | 04-18-2013 |
20120160525 | VIDEO-BASED FIRE DETECTION AND SUPPRESSION WITH CLOSED-LOOP CONTROL - 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. | 06-28-2012 |
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 |
20120008832 | REGION-OF-INTEREST VIDEO QUALITY ENHANCEMENT FOR OBJECT RECOGNITION - 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. | 01-12-2012 |
20110103641 | VIDEO-BASED SYSTEM AND METHOD FOR FIRE DETECTION - A video recognition system detects the presence of fire based on video data provided by one or more video detectors, but suppresses the triggering of an alarm in situations based on the selection of acceptable regions and application of rules associated with each acceptable region. A user defines acceptable regions within the field of view of the video detector and associates with each acceptable region a rule. During processing of video data associated with the field of view, video metrics are calculated and analyzed to detect the presence of fire (e.g., flame or smoke). Prior to triggering an alarm, regions identified as indicative of fire are compared with the user-defined acceptable regions. If there is overlap between the two regions, the rule associated with the acceptable region is applied to determine whether the alarm should be suppressed or triggered. | 05-05-2011 |
20100052903 | Voice recorder based position registration - A system and method for monitoring a location having at least one sensor for sensing a change in at least one condition using voice tags to announce alarms. The system includes a registration process where a voice recorder and a digital conversion unit form digital voice tags from recorded speech representing the type and location of sensors. The voice tag is sent as part of an alarm message or pre-stored in a control panel for later retrieval such that the type and location of an alarm is reproduced vocally at the time of the alarm. The registration process may be completed with a registration module which may be a keypad or the voice recorder may be included in the sensors. Additional features include sensor location change notification to ensure the stored voice tag represents the current location of the sensor. | 03-04-2010 |
