Abstract: A valve assembly failsafe configured to be coupled to an actuator of a coolant control regulator assembly is provided. The valve assembly failsafe includes a wind arm, a spring that engages the wind arm under spring tension, a latch that engages the wind arm, a drive gear that engages the wind arm and the actuator, and a driver that engages the latch.

Abstract: A noise reducing pipe system may include a pipe having a first end and a second end. The system may also include a pipe coating connected to the pipe and extending continuously around the circumference of the pipe. The pipe coating may also extend substantially the length of the pipe. The first end and the second end of the pipe have an exposed portion that does not have the pipe coating connected thereto. The exposed portion on each of the first end and the second end is defined as having a length equal to one half an inside diameter of the pipe. There is no space between the pipe coating and the pipe so that substantially all portions of an outer wall of the pipe are in contact with the pipe coating.

Abstract: A threshold logic element (TLE) is disclosed. The TLE includes a first input gate network, a second input gate network, and a differential sense amplifier. The first input gate network is configured to receive a first set of logical signals and the second input gate network configured to receive a second set of logical signals. The differential sense amplifier is operably associated with the first input gate network and the second input gate network such that the differential sense amplifier is configured to generate a differential logical output in accordance with a threshold logic function. To obfuscate the TLE, any number of obfuscated transmission gates can be provided in one or both of the input gate networks. The obfuscated transmission gates are obfuscated such that obfuscated transmission gates are incapable of effecting the threshold logic function of the TLE and thus hide the functionality of the TLE.

Abstract: The invention provides systems and methods for providing compressed video data from multiple bit streams. The systems and methods apply a two-stage strategy. In the first stage, a conditioning step is performed on a bit stream comprising compressed video data which outputs a conditioned bit stream that is able to receive digital insertions without subsequent decompression of the compressed video data or removal from network packets. The conditioning includes recoding an incoming bit stream such that compressed video data in the bit stream immediately before and after a splice point does not have temporal reliance across the splice point. In the second stage, e.g., at a downstream network device, splicing of compressed video data from a second bit stream into the conditioned bit stream is performed. The splicing takes advantage of the changes made to the conditioned bit stream and may occur at the network packet level.

Abstract: Effects of diffraction of a spectral beam from an edge of the micromirrors are reduced in order to optimize the passband in a wavelength selective switch. The effects of diffraction on the pass band may be reduced by using rotation of the micromirror about both the attenuation axis and the switching axis to achieve the desired level of attenuation. Peak coupling can be attained by dithering the micromirror about a dither axis that is tangent to a contour of constant attenuation using simultaneous rotation about the switching and attenuation axes. A power level of a spectral channel may be attenuated by rotating the channel micromirror with respect to an effective attenuation axis that is non-orthogonal to the dither axis through a combination of rotations about the switching axis and the attenuation axis.
