Abstract: Disclosed is an RF (Radio Frequency) power source having a power supply configured to convert an AC (Alternating Current) voltage at a power supply input to a second voltage at a power supply output, and an RF generator configured to receive the second voltage at an RF generator input and to use the second voltage to produce an output RF signal at an RF generator output. According to an embodiment of the disclosure, the power supply performs the voltage conversion without galvanic isolation between the power supply input and the power supply output, which can increase energy efficiency while reducing complexity and cost as well. Instead, the RF generator is provided with galvanic isolation between the RF generator input and the RF generator output, which can be sufficient for achieving galvanic isolation between the power supply input and the RF generator output for safety reasons.

Abstract: A thermal break system for cast-in-place concrete slabs is provided that includes a load-bearing structural foam barrier designed to separate an interior portion of concrete slab from an exterior portion of concrete slab. The thermal break system includes a plurality of reinforcing tension bars holes passing through the insulating barrier. In addition, reinforcing shear bars are inserted through the insulating foam at a non-horizontal angle and bent such that the shear bars are horizontal on either side of the insulating barrier.

Abstract: A temperature control system and method for regulating a liquid temperature in a recirculation system of a molding system includes determining an operating pressure of the liquid in the recirculation system, determining an operating temperature of the liquid in the recirculation system, receiving the operating pressure and the operating temperature, comparing the received operating temperature to a threshold temperature as a function of the operating pressure, and adjusting an output of a heat exchanger in the recirculation system when the operating temperature is beyond the threshold temperature.

Abstract: A method, amplifier and system are provided for enabling power recovery from a narrow-band antenna when a signal having bandwidth exceeding that of the antenna is utilized. The amplifier provides amplification of a source signal to the antenna and recovery of power stored in the antenna during periods when the impedance of the antenna is negative to enable reverse current through the amplifier to a direct current (DC) power source.
