The multiple hazard marker further has collapsible elements that expand upon deployment, a signaling device, a receiver for activating the signaling device and transmitter associated with the signaling device. The deployment device for deploying the multiple hazard marker collapses and retains the multiple hazard marker in the deployment device until a releasing mechanism releases the multiple hazard marker from the deployment device at deployment.

  • Patent number: 6414598
    Abstract: The alarm system is capable of detecting both conductive and non-conductive liquid level increases, designed for indoor operation, and ideally suited for detecting basement flooding or leaky domestic steel oil tanks or other fluid containment devices. A float, positioned above any surface such as a contained area (sump or drip pan), rises with the presence of a liquid, allowing a spring-loaded switch to rise, triggering a 9-volt powered battery electric circuit. The electric circuit, enclosed in a plastic enclosure, activates an audible pulsating alarm when triggered. A battery voltage monitor incorporated in the electric circuit, tests the battery voltage on a continuous bases, and will trigger the unit into the alarm mode when the battery voltage is insufficient to sustain continuous operation. A simple convenient self check feature allows the user to simply check the unit at any time.

  • Patent number: 6373385
    Abstract: A water sprinkler based deterrent system is used to deter entry into landscaped areas by undesirable intruders. The system incorporates an infrared detector combined with a control circuit that is adapted to be powered from a wide range of power supplies. In this manner, the system can be easily integrated into a variety of landscape environments, including those that may or may not include a preexisting sprinkler controls system.

  • Patent number: 6359568
    Abstract: The present invention is a rescue device including a casing having a hollow interior area. The casing includes an opened top and enclosed bottom. Removably secured to the opened top is a lid. Located within the casing is a gas cylinder, having a gas that is lighter than air. This gas cylinder is coupled to a collapsible and inflatable balloon. A sensing mechanism is coupled to a valve. This valve is coupled to the gas cylinder. Once a change in the electrical potential is detected via the sensing mechanism, it triggers the valve. This will cause the valve to open and hence allow for the gas to enter and fill the balloon. During the inflation process, the balloon expands and inherently causes the top to be lifted and remove for allowing the balloon to float and travel upwards. The balloon is maintained to the device via a tether.

  • Patent number: 6271763
    Abstract: The bases of an audible alarm unit and an audible/visible alarm unit are configured to be used interchangeably with a single cover. The cover has an opening that receives a projecting wall portion on the base of the audible alarm unit and a receptacle for a strobe lamp unit on the base of the audible/visible alarm unit. The bases have mounting holes that enable the alarm units to be mounted on several types of standard backboxes, the cover concealing the screw holes for good appearance of the installed units.
