Abstract: There is provided an integrated articulating thermal isolation system having an articulating actuator assembly, a support frame assembly, and a thermal blanket assembly. The thermal blanket assembly has a pair of non-articulating blankets positioned on exterior surfaces of the support frame assembly and a pair of articulating blankets disposed between the non-articulating blankets. Each articulating blanket has a plurality of stiffener elements. The system further has a harness assembly, a deployable assembly interface element, and a vehicle interface element. When the articulating actuator assembly is actuated, the articulating blankets are guided by the support frame assembly from a stowed position to a deployed position through motion of the articulating actuator assembly.

Abstract: An electronic switching ballast for fluorescent lamp having a rectifying circuit, a square generator, a phase discriminator, a switching time differentiating circuit and a wave shaping circuit. The alternating current input signal provided to the ballast is rectified by the rectifying circuit to a direct current signal. The square generator generates a square wave signal in reference to the direct current signal. The phase discriminator compares a feedback signal from the wave shaping circuit with a reference signal corresponding to the direct current signal to provide a full-wave rectified signal. The switching time differentiating circuit combines the square wave signal and full-wave rectified signal, and differentiates the combined signal to generate a pair of pulsed signals. The pulsed signals are out of phase with respect to one another.
