A vibration isolating thermally conductive connector includes a first thermally conductive element configured to draw heat from a heat source, a second thermally conductive element separated from the first thermally conductive element, and a flexible seal connected with the first and second thermally conductive elements and defining an enclosed cavity between the elements. The enclosed cavity contains a thermally conductive liquid, and allows limited movement of the second and first thermally conductive elements with respect to each other while maintaining thermal connection.

An unmanned vehicle capable of operating in harsh environments is disclosed. The unmanned vehicle includes an aerial platform, a piloting system supported by the aerial platform, a medium source supported by the aerial platform, and a control system having a processor running computer executable code that actuates the medium source to emit a medium away from the aerial vehicle with an intensity sufficient to disorient a subject when the medium interacts with an exteroceptive sense of a subject.

An unmanned aerial vehicle (UAV) includes a housing forming a central body of the UAV and including an internal compartment, one or more electrical components disposed within the internal compartment and configured to affect operation of the UAV, and an inertial measurement unit (IMU) disposed in an external compartment external to the central body. The IMU is isolated from the internal compartment such that a barometric pressure in the external compartment is independent of a barometric pressure in the internal compartment.

An energy delivery system includes: a solar cell configured to receive solar energy and generate electrical energy; an electrolysis module configured to generate a first fuel from water; a fuel cell configured to generate electricity by reacting the first fuel with a second fuel through an electrochemical reaction, wherein the electricity is used to power a movable platform; and a controller configured to generate instructions for the solar cell to provide the electrical energy to one or more of: (1) the electrolysis module to effect operation of the electrolysis module, and (2) the movable platform.

A power module includes a turbine arranged along a rotation axis, an interconnect shaft fixed in rotation relative to the turbine, and a compressor with a regenerative compressor wheel. The regenerative compressor wheel is fixed in rotation relative to the interconnect shaft supported for rotation with the turbine about the rotation axis. Generator arrangements, unmanned aerial vehicles, and methods of generating electrical power are also described.

A cell device including a cell module and at least one temperature adjusting module is provided. The temperature adjusting modules are configured on the cell module in a heat conduction manner. Each of the temperature adjusting modules includes a thermoelectric cooling chip. The thermoelectric cooling chip has a first surface and a second surface opposite to each other. The thermoelectric cooling chip is configured to receive a first electric signal to heat the first surface and cool the second surface. The thermoelectric cooling chip is configured to receive a second electric signal to cool the first surface and heat the second surface. A vehicle including the cell device is also provided. The cell device of the disclosure is capable of implementing active temperature control and has good temperature control effect. The vehicle of the disclosure is capable of implementing active temperature control, and has a wider usage environment temperature.

Systems, methods, and devices are provided herein for removing a byproduct of a fuel cell from a vehicle. The vehicle comprises a fuel cell and a venting system. The fuel cell is in communication with a fuel storage container. The fuel is configured to generate electricity and a byproduct, by reacting a first fuel from the fuel storage container with a second fuel through an electrochemical reaction. The venting system is configured to expose the byproduct to forced convection.

The unmanned vehicle includes an aerial platform, a piloting system supported by the aerial platform, a medium source supported by the aerial platform, and a control system having a processor running computer executable code that actuates the medium source to emit a medium away from the aerial vehicle with an intensity sufficient to disorient a subject when the medium interacts with an exteroceptive sense of a subject.

An unmanned aerial vehicle (UAV) includes a heat dissipation device, an inertial measurement unit (IMU), and a control module. The heat dissipation device includes an air guiding cover and a heat conduction plate. The air guiding cover includes an air duct configured to guide an airflow, and the heat conduction plate directly constitutes a portion of a sidewall of the air duct. The IMU module is received within the air duct. The control module is located outside the air duct and disposed at a side of the heat conduction plate that faces away from the IMU module. Heat generated by the IMU module is taken away directly by the airflow within the air duct.

A cooling shroud assembly for an engine is disclosed. This cooling shroud assembly includes a shroud body. There is an inlet door or flap to an interior of this shroud body, along with an outlet door or flap from this shroud body. When installed on an engine that is incorporated by a moving vehicle (e.g., aircraft, unmanned aerial vehicle, radio-controlled aircraft, watercraft), airflow through the shroud body from an inlet to an outlet. The position of the inlet and outlet doors may be adjusted (e.g., simultaneously) to change the airflow through the shroud body, and to thereby change the dissipation of heat from the operating engine via this airflow.
