摘要： An electrical energy generator relying upon piezoelectricity includes electrical generating elements comprising electroded bodies of an electrostrictive material, e.g., polyurethane, having inherent but weak piezoelectric characteristics. A d.c. bias is applied between the electrodes for field-inducing a larger piezoelectric characteristic whereby, upon applying mechanical energy to the element, in known manner, for alternately straining and destraining the body, electrical charge is generated on the electrodes with a high mechanical energy to electrical energy conversion efficiency.

摘要： A wave energy converter (WEC) including an electric generator for capturing energy contained in ocean waves and converting it to electrical energy at the output of the electric generator may be characterized as an effective capacitive (or inductive) element. Systems embodying the invention include an inductive (or capacitive) element inserted in the circuit between the output of the electric generator and a load in order to achieve resonance with the effective capacitance (inductance) of the WEC and so as to increase the efficiency of the power transfer to the load. In certain embodiments the load coupled to the system has an optimum value which is made a function of the frequency of the ocean waves and the effective capacitance (or inductance). The effective capacitance (inductance) of the converter varies as a function of the frequency of the ocean waves. Accordingly, systems embodying the invention may include a controller for varying the load and/or the inductive (capacitive) element coupled in the system to resonate with the converter for increasing the efficiency of the system.

摘要： A transducer operated as power generating device is driven at a low frequency and collects energy at the low frequency rate. The collected energy is extracted at a much higher frequency. Extracting the energy at a higher frequency enables the use of components, such as inductors, having reasonable values and sizes. In one embodiment, a power extracting circuit which includes elements designed to resonate with the transducer at a higher frequency than the frequency at which the transducer is being driven is periodically switched in circuit with the transducer. Thus, the electric power generator device operated and controlled by a slowly changing source of energy (e.g., ocean waves, wind, eddies of water) may develop energy at one frequency and may be operated to transfer the energy at another frequency. The resonating circuit is switched into circuit with the transducer on the positive and negative peaks of the force driving the transducer for a time approximately equal to Tc, where Tc is equal to approximately ½fo, where fo is the resonant frequency of the circuit with the switch closed. In another embodiment the load applied to the circuit is designed to have an optimum value to optimize the power transfer. Other embodiments include circuits for reliably and accurately detecting the peak(s) of the driving input signals.

摘要： Systems and circuits embodying the invention include means for sensing at least one of the peaks, amplitude and frequency of an oscillatory input force impinging on a power generating device for controlling the turn-on of a switch used to transfer energy collected by the power generating device to an associated load. The power generator may be a transducer such as a piezoelectric device or a wave energy converter (WEC). Sensors and sensing means embodying the invention are used to control the point in time at which power extracting circuits are switched in circuit with the power generating device. The power extracting circuit may include components which can resonate with the power generating circuit at a higher frequency than, and independent of, the frequency at which the power generating device is being operated. Thus, an electric power generator device operated and controlled by a slowly changing source of energy (e.g., ocean waves, wind, eddies of water) may develop energy at one frequency and may be operated to transfer the energy, at a selected point in time, at another frequency.

摘要： For the purpose of converting the mechanical energy of surface waves on bodies of water, a power generating piezoelectric structure (10) is provided comprising piezoelectric material members, preferably in the form of one or a laminate of sheets (14) of such material, each sheet having an electrode (24) on opposite surfaces thereof. Each pair of electrodes and the piezoelectric material therebetween define a power generating element, each of which is preferably dimensioned, relative to the wave lengths of selected waves on the body of water in which the generator is to be used, for increasing the efficiency of power conversion. A support means (12) is provided for maintaining the structure in a preselected position within and below the surface of the water. Preferably, the piezoelectric generating elements are flexible and are supported in such manner to allow flexure thereof in response to movement of the surrounding water. In certain embodiments, the elements are designed to enter into mechanical resonance in response to the passage of waves thereover, such flexure and/or resonance increasing the mechanical coupling efficiency between the waves and the elements.

摘要： A plurality of signals to be separated in time as well as in frequency areimultaneously applied to the input of a power amplifier whose output is applied to the input of a fast-tuned filter. The filter is capable of being almost-instantaneously tuned to any of the frequencies of the input signals to control the output at any given time or combinations of times. The filter is in the form of a coaxial section with an input to the inner conductor of the coaxial section and the output taken from a strip line, parallel to the inner coaxial conductor, coupled to a coaxial output cable at the top of the coaxial filter. The tuning is by a plurality of inductive spokes positioned at various locations within the filter, and connected between the inner and outer coaxial conductors by switching diodes, that are externally controlled, to provide almost instantaneous control of the resonant frequency of the filter.

摘要： A magnetic braking system for inhibiting excessive motion between a float and a column intended to be placed in a body of water; with the float and column moving relative to each other as a function of the waves present in the body of water. The braking system includes a permanent magnetic assembly (PMA) mounted on, and attached to, one of the float and column and a coil assembly (or a conductive plate) mounted on, and attached to, the other one of the float and column. The braking system is mounted such that motion between the float and the column is inhibited when the displacement of the float relative to the column exceeds a predetermined operating range.
