Abstract:
Systems and methods for current sensing are described. The described systems and methods utilize a comparator for generating a current sense signal based on comparing an output current of a circuit against a reference current. The reference current is generated by using a current sourcing circuit that is connected to a controllable current source.
Abstract:
Dynamic biasing methods and circuits are described. The described methods generate bias voltages that are continuously varied so as to control stress voltages across transistors used within a cascode stack.

Abstract:
The disclosure teaches improvements of the lever operated pivoting float with generator. The improved parts include an improvement in the torsion spring system, more streamlined floatation, counter weighted and ballast balanced, buoyant lever arm and a shock absorbing lever arm. The device can also be use up side down. The disclosure also teaches a floating electric power generator including a buoyant float component, a lever arm pivoting on a shaft of the float and attached to a submerged structure, and an electrical generator that includes a shaft that turns in response to the pivoting of the lever arm. Also disclosed is a floating electric power generator including a float in a “U” or horseshoe shape with an opening for mounting the pivoting lever arm on a shaft, a generator contained within one arm of the float, a combination spring and shaft component wherein the springs are compressed by pulling down of the pivoting lever arm, and energy from the compression or relaxation of the power is communicated to the generator shaft to power the generator. The disclosure teaches a floating electric power generator comprising: a float in a “U” or horseshoe shape with an opening for mounting a pod shaped pivoting lever arm on a shaft, a generator contained within the lever arm pod, a chain, coil spring and end cap configuration in communication with a shaft within the lever arm wherein the chain is wrapped about the shaft when the lever arm is pulled down and thereby compressing the spring, a gear component on the shaft in communication with at least one other gear fixed to the generator rotating shaft so that as the lever arm rotates about the shaft, the generator rotating shaft is turned. The pod holds the weight of the generator and the generator acts as a counter weight and ballast to force the back end of the float under as it is lifted out of the water. The pivoting floatation device has large ends and thinner mid sections so that the float will enter the water smoothly.
Abstract:
A non-rigid inflatable gas storage apparatus comprising a plurality of layers of which one is gas impermeable and at least one controllable gas inlet and outlet component wherein the apparatus is substantially spherical when inflated and has a diameter of approximately 10 ft to 40 ft and can store gas at a range of pressure between 140 psi and 500 psi.
Abstract:
An air compression system for use on the ocean surface comprising an air compressor within a moveable float. The float also contains a drive rack engaged with a drive gear wherein the float moves substantially vertically up and down on the drive rack in response to ocean waves. The float also includes a retention spring to return the float vertically upward and a drive pulley connected to the drive gear moving in response to the float moving along the drive rack and powering the air compressor within the float. Also included is a method of utilizing wave motion to compress air comprising the steps of installing a float at the ocean surface wherein the float can move substantially up and down in response to wave motion and installing a drive rack within the float wherein one end of the drive rack is fixed to a beam that is relatively stable. The method further comprises placing a rotating drive gear that engages the drive rack and rotates as the float moves in relation to the drive rack, placing the rotatable drive gear in communication with further moveable component; and placing the moveable component in communication with a moveable piston of an air compressor.
