20080202407 | Theft Deterrent System and a Device For Use in Said System - The invention concerns a theft deterrent device ( | 08-28-2008 |
20100012016 | Selectable field motion detector - A detection field selectable motion sensor that includes a modulator having a output with a shaped response to received radiation emissions forming a detection field and a sensor configured to detect the output from the modulator. The motion sensor can be configured with a set of lenses that can be aligned with the sensor. Further, the motion sensor can be an active sensor that transmits electromagnetic radiation which is detected after reflection from a detection field. Infrared radiation is the preferred source of received and transmitted radiation but microwave or visible light can be used. For an active motion detection either coherent or incoherent radiation can be used. The motion sensor includes a means for mounting and a hinge or swivel for orientating the sensor. | 01-21-2010 |
20100288180 | Automotive Power Window Intrusion Detection - A system detects forced opening of a power window of a motor vehicle. An electric motor is responsive to a drive signal to provide a torque to selectably open or close the window. A regulator couples the electric motor to the window for transferring the torque into an opening or closing force on the window. A sensor is coupled to the electric motor responsive to a back voltage produced by the electric motor when an external force on the window glass opens the window glass when the drive signal is not present. A vehicle security system is coupled to the sensor for generating a perimeter alarm condition in response to detection of the back voltage by the voltage sensor. | 11-18-2010 |

20100288181 | IMPACT SENSING MULTI-LAYERED PLASTIC MATERIAL - A method and apparatus for detecting encroachment of property perimeters or boundaries employing a multi-layer structure having an inner layer of polyvinylidene fluoride having piezoelectric properties disposed between and joined with two outer layers of an electrically conductive plastic material. The multi-layer structure is connected with an electrical signal detector and buried at a boundary or property perimeter. The buried multi-layer structure is monitored for generation of an electrical signal. Detection of an electrical signal corresponds to an encroachment of the property perimeter or boundary. | 11-18-2010 |
20140048009 | ALARM MAT - An alarm mat includes a sheet, and sound producer from which sound is produced by air inflow and outflow. The sheet is provided with a plurality of projections made of an elastic material, projecting toward an upper-surface side of the sheet with top portions thereof continuously extending, and each having a sealed cavity inside. The plurality of projections are juxtaposed to each other. The sound producer is loaded in the sheet in a manner that air flows in and out of the projections through the sound producer alone. | 02-20-2014 |

20090277374 | APPARATUS AND METHOD FOR STORAGE TANK HATCH MONITORING IN AN INVENTORY MANAGEMENT SYSTEM - A method includes receiving information associated with a level of material in a tank, where the tank has a hatch. The method also includes determining whether the level of material in the tank experiences a specified variation within a critical zone associated with the hatch. The specified variation is indicative of the hatch being open while the tank is being filled. In addition, the method includes generating an alarm when the level of material in the tank experiences the specified variation. Determining whether the level of material in the tank experiences the specified variation could be based on an entrance level speed of the material, which identifies a rate at which the level of material in the tank is increasing when the material level crosses a lower bound of the critical zone. Also, no alarms could be generated when the level of material in the tank is outside the critical zone. | 11-12-2009 |
