Abstract: An actuator in an HVAC system is provided. The actuator includes a motor and a drive device. The drive device is driven by the motor and coupled to an HVAC component for driving the HVAC component between multiple positions. The actuator further includes a processing circuit. The processing circuit is coupled to the motor and configured to transmit control signals to operate the motor to drive the HVAC component between a first position and a second position, monitor temperature data received from one or more temperature sensors, determine that the temperature data does not meet an expected performance criterion and transmit an alarm signal.

Abstract: A hazard beacon has an interface to a vehicle wiring harness configured to detect that vehicle emergency indicators have been deployed, a plurality of separately strobe capable light segments forming a hazard symbol, and a microcontroller controlling operation of the plurality of separately strobe capable light segments.

Abstract: A jet injector system for injecting fluid into a body. The jet injection system includes capsules for holding the material to be injected, apparatus for applying force to the capsule(s) to eject the injection material(s) and a perforator for directing the jet stream for the respective materials into the body. A flyweight system is described for developing jet injection pressures, and latching devices control the flyweight system. An injector system for injecting more than one fluid is described.

Abstract: The invention includes liquid weighted, variable inertia flywheels of various designs together with subsystems to selectively control the addition of liquid into and the removal of liquid from the flywheels while the flywheels rotate. In one embodiment liquid is removed and energy extracted through centrally mounted turbines. In other embodiments, liquid is extracted through various rotatable Pitot tube devices. In yet another embodiment liquid is added and removed through bucket wheels supported for rotation on a centrally located, independently rotatable carrier. Pairs of flywheels are further incorporated into continuously variable transmissions, together with fluid control devices to vary the fluid levels in and thus the moment of inertia of each of the flywheels for energy storage and extraction.

Abstract: A flywheel energy storage system with a continuously-variable output speed employing a pair of variable inertia flywheels for energy storage and transfer and a second pair of variable inertia flywheels for control of the inertia of the first flywheels. A gear type transmission is provided for coupling each of the flywheels to an input shaft and each of the flywheels with an output shaft with multiple output shaft speed ranges. A system for automatic control of shifting is provided.

Abstract: Rotatable blades are tuned by forming a plurality of ribs on concave air foil surfaces of the blades adjacent trailing edges in longitudinal alignment with the fluid flow.
