    摘要： An audio broadcasting signal disruption sensor and backup program source for providing an alternate audio programming sources in the event of primary-source audio programming failure so as to automatically switch to a backup alternate audio programming source feeding an output audio stream for broadcasting. The system includes monitoring an audio stream from a primary-sources audio programming output, detecting a substantially constant amplitude waveform in the audio stream, determining that the substantially constant amplitude waveform remains of substantially constant amplitude continuously for a threshold period of time, switching the output audio stream from the primary-source audio programming to the alternate audio programming source upon expiry of the threshold period of time, and providing notice of any main-source audio programming failure to administrative personnel.

    摘要： There are disclosed two forms of load lifting and lowering unit for attachment to a vehicle. The units are of the kind in which a load platform is carried between two parallel spaced-apart articulated parallelogram linkages, movable in unison up and down guide members spaced across an access opening of the vehicle to raise and lower a load to and from the access opening. An inextensible tie member, pivotally connected between the platform and a swinging arm of the parallelogram linkage, causes the platform automatically to close off the access opening when the linkages are folded towards the vehicle. In one embodiment, the swinging arm cooperates with a fixed stop during upward movement of the linkages to effect such closure: in the other embodiment, a fluid operated ram swings the platform upwardly about its pivot to fold the linkages towards the vehicle and cause the platform to close off the access opening.
