Patent number: 6043636Abstract: A voltage transient suppression circuit includes a capacitor, a diode, and a voltage limiter. The negative terminal of the capacitor can be coupled to the negative terminal of a variable voltage circuit element (e.g., a switching device, a series impedance, or a load). The anode of the diode can be coupled to the positive terminal of the variable voltage circuit element, and the cathode of the diode is connected to the positive terminal of the capacitor. The voltage limiter is connected in parallel with the capacitor. When the voltage applied across the voltage limiter is above a predetermined voltage, current is allowed to conduct through the voltage limiter and a voltage potential drop across the voltage limiter is substantially independent of the current conducted therethrough. When the voltage applied across the voltage limiter is below the predetermined voltage, current is substantially prevented from passing through the voltage limiter.Type: GrantFiled: October 20, 1997Date of Patent: March 28, 2000Assignee: Diversified Technologies, Inc.Inventors: Marcel P.

Patent number: 5942991Abstract: Apparatus, and related method, for remotely measuring at 1east one environmental condition includes an electromagnetically resonant sensor having a measurable resonance characteristic (e.g., center resonance frequency, quality factor, or bandwidth) that varies in correspondence to changes in the environmental condition present at the sensor. The sensor emits an electromagnetic return signal representative of a state of the resonance characteristic when an electromagnetic excitation signal impinges on the sensor. The electromagnetic excitation signal is generated by a generator located separate and away from the sensor, and the excitation signal is then directed at the remote sensor. The sensor thus remotely detects and measures the environmental condition. In one embodiment, the sensor is an electromagnetically resonant electrical circuit. In another embodiment, the sensor is an antenna resonator (e.g., a half-wavelength antenna) made of a conductive material.Type: GrantFiled: June 6, 1995Date of Patent: August 24, 1999Assignee: Diversified Technologies, Inc.Inventors: Marcel P.

Patent number: 5782196Abstract: A remotely-operated unmanned vehicle attached to the hull of a marine vessel by electromagnets surveys the hull for damage. The vehicle attached to the hull is electronically controlled from a remote location. An imaging system on the vehicle provides an operator with images of the vessel's hull and the surrounding environment. Once damage has been found and assessed, the vehicle applies a patch over the damaged opening in the hull to prevent cargo outflow and water inflow. The patch, which resists puncturing and tearing, is constructed from one or more sheets of flexible material having dimensions appropriate to cover most openings.Type: GrantFiled: October 4, 1996Date of Patent: July 21, 1998Assignee: Diversified Technologies, Inc.Inventors: Christopher C.
