Abstract: A system and method for detecting a failure in a redundant signal path during operation of the redundant path is disclosed. A test signal is sequentially injected into each signal path while an input signal is conducted by the other signal path not receiving the test signal. The test signal is selected at a frequency to verify operation of a filter connected in series along each path. A processor generates the test signal, injects the test signal at the input of the filter, and receives the output of the filter. The processor then generates a frequency response of the filter in each signal path as a function of the output from the filter and of the original test signal. The frequency response obtained along each of the redundant signal paths is compared to each other to detect a failure of one of the filters present along the respective signal paths.

Abstract: Provided herein are pyridine and pyrimidine carboxylates and their derivatives, and compositions and methods of use thereof as herbicides.

Abstract: Aspects of the subject disclosure may include, for example, a method in which a processing system acquires a video image and voice data of a remote viewer of a live event content and generating animation parameters relating to the video image. An avatar of the viewer is constructed based on the animation parameters; the avatar includes an animated version of the video image. The animated version and voice data are encoded to obtain a compressed animation data stream and a compressed audio stream, which are transmitted at a low bit rate to a remote system providing the content. The remote system aggregates compressed animation data streams and compressed audio streams to obtain a virtual audience for the event; the virtual audience includes avatars of the remote viewers and sound produced by the remote viewers. Other embodiments are disclosed.

Abstract: An adjustable pillow including an outer shell, an inner top layer and an inner lower layer, a flexible bladder located between the inner top and lower layers, a closure mechanism located in the pillow that can be used to open and close an opening in the pillow, and a plurality of soft support members that can be inserted into and removed from the bladder. Each member includes a round core and a plurality of projections extending from the core. The pillow may also include a controller that communicates with a mobile device in order to monitor a user's sleep and provide sounds and movements that help the user fall asleep.
