  • Patent number: 12080497
    Abstract: The present invention is a variable control switch. In particular, it is a control switch with modifiable variables for activation and deactivation of primary and secondary devices. The control switch has an input plug and two output plugs. The control switch has a sensing circuit connected between the input plug and two output plugs and has an output comprising DC voltage varying proportionally to the current passing between said first and second output plugs. The sensing circuit is connected to a microcontroller unit that controls current to the first or second outputs based on a set of pre-determined variables, including a termination threshold.
    Type: Grant

  • Patent number: 7144139
    Abstract: A system with a pair of flange extrusions and a base extrusion having a channel for electrical leads and lighting. A preferred embodiment has a base extrusion of polyvinyl chloride (PVC) of 89–98 Duro on the Shore OO scale. The base extrusion is connected, on opposite sides of the channel, to a first flange extrusion and a second flange extrusion of PVC with a hardness of preferably of 90 Duro. Electrical leads are placed in the channel. A lens is inserted into the channel over the leads. A replaceable LED module having a circuit board secured to a module base is attached to the leads. The circuit board preferably has a gasket or seal, an LED and two contact teeth that make electrical contact with the leads.

  • Patent number: 7063441
    Abstract: The present invention is a soft light fixture. In particular, it is an LED soft light fixture. The preferred embodiment of the soft light fixture has a plurality of light emitting diodes mounted on a perimeter ring aimed to emit light into a light-mixing chamber. The perimeter ring supports a light deflection cap with a lens, preferably translucent. The ring, deflection cap and lens define the light mixing chamber which blends light from the plurality of light emitting diodes into a single light source.

  • Patent number: 6032498
    Abstract: A security system for securing personal property at a beach including two augers is provided. A pair of augers (15,16,50,100) are screwed into the sand. A crossbar (11,102) placed in loops (13,14,56) on the exposed ends of the augers. The crossbar is locked to the augers so that the augers may not be unscrewed from the sand. Items of personal property (31,140) may then be locked to the security device formed by the augers and crossbar.
