  • Patent number: 10541357
    Abstract: The invention relates to a method for cyclical operation of a thermoelectric cell arrangement by periodically changing the temperature of the thermoelectric cell arrangement, wherein the thermoelectric cell arrangement is thermally coupled to a cyclically operated absorption heat pump. The following method steps are carried out cyclically: thermally coupling the thermoelectric cell arrangement during a cooling phase to a cold side of the absorption heat pump, thermally coupling the thermoelectric cell arrangement during a heating phase to a hot side of the absorption heat pump. The invention also relates to a harvester device for generating electrical energy by means of a thermoelectric cell arrangement, wherein the thermoelectric cell arrangement is thermally coupled to an absorption heat pump, wherein the thermal coupling makes it possible to effect, in time with the working cycle of the absorption heat pump, a temperature change in the thermoelectric cell arrangement.

  • Patent number: 10460717
    Abstract: The present disclosure is directed to controlling, reducing, and/or altering sound generated by an aerial vehicle, such as an unmanned aerial vehicle (“UAV”), while the aerial vehicle is airborne. For example, one or more transducers, such as piezoelectric thin-film transducers, or carbon nanotube transducers may be applied or incorporated into or on the surface of propeller blades that are used to aerially navigate the aerial vehicle. As the propeller blade rotates and generates sound, the transducers may be activated to generate one or more anti-sounds that cancel, reduce, or otherwise modify the sound generated by the rotation of the propeller blade. The anti-sound combines with the sound and causes interference such that the combined, or net-effect, is an overall cancellation, reduction, or other modification of the sound.

A piezoelectric material is additionally coupled to the vane, arranged such that a deflection of the free end of the vane generates stress acting on the piezoelectric material. When the piezoelectric converter is illuminated with a radiant flux, the differing emissivities of the first and second surfaces produce a temperature gradient across the vane and a thermal creep force across the planar surface generates a deflection of the vane, and a subsequent voltage induced by the stress on the piezoelectric material generates a voltage between a first electrode and second electrode in electrical contact with the piezoelectric material.

  • Patent number: 9267962
    Abstract: A single-chip scanning probe microscope is disclosed, wherein the microscope includes an isothermal two-dimensional scanner and a cantilever that includes an integrated strain sensor and a probe tip. The scanner is operative for scanning a probe tip about a scanning region on a sample while the sensor measures tip-sample interaction forces. The scanner, cantilever, probe tip, and integrated sensor can be fabricated using the backend processes of a conventional CMOS fabrication process. In addition, the small size of the microscope system, as well as its isothermal operation, enable arrays of scanning probe microscopes to be integrated on a single substrate.

  • Patent number: 9109818
    Abstract: System and methods are disclosed for controlled thermal energy transfer. The system includes a thermal energy source, a thermal energy sink, spaced apart from the thermal energy source, an electrocaloric structure carried by a suspension and configured for alternating physical movement between thermal communication with the thermal energy source and thermal communication with the thermal energy sink, and a control signal source simultaneously providing both a temperature control signal for controlling the temperature of the electrocaloric structure and a movement control signal for controlling the alternating physical movement of the electrocaloric structure between thermal communication with the thermal energy source and thermal communication with the heat sink. Heating or cooling of a desired element may be provided. Movement control may be electrostatic, magnetic, mechanical, etc., and is self-synchronizing with the field employed for temperature control in the electrocaloric structure.

  • Patent number: 9035534
    Abstract: The electrical energy generating system of the present invention comprises a piece of alignment Buckypaper, an energy generator, a thin deposition and two contacts. The alignment Buckypaper is a thin sheet made from an aggregate of carbon nanotubes. The thin deposition is formed on at least one surface of the alignment Buckypaper by electrolysis to form a semimetal material. A contact is connected with the upper surface of the alignment Buckypaper and the other contact is connected with the lower surface of the alignment Buckypaper. In use, the energy generated by the generator is inputted to the alignment Buckypaper. The energy then ionizes the molecules contained in the alignment Buckypaper. The positive charges move to the upper contact and the negative charges move to the lower contact. Such electrical energy may then be fed to a load connected with the two contacts to do work on the load.
