Abstract: A rollover mitigation device for a motor vehicle comprises a frame mounted to a roof assembly within which is disposed a transversely mounted deployable rollover protector shaft. The frame comprises a pair of lateral mounting rails mounted to the roof assembly and a tubular cross member extending between the pair of lateral mounting rails. The deployable rollover protector shaft is substantially disposed within the tubular cross member when in the stowed position and is actuated from the stowed position to a locked deployed position by a spring disposed within the tubular cross member. A controller actuates a release lock to release the deployable rollover protector shaft to the deployed position upon a sensor detecting a roll angle of the motor vehicle exceeding a predetermined value. A deployment lock restrains the deployable rollover protector shaft in the deployed position.

Abstract: Approaches for creating video on demand (VOD) assets with a VOD watermark. For a digital stream yet to be broadcast, a duplicate version of an accompanying audio stream comprised within the digital stream is created. A video on demand (VOD) watermark is inserted into or affixed within the duplicate version of the accompanying audio stream. Thereafter, the digital broadcast stream which comprises the original audio stream and the duplicate version is transmitted to an integrated receiver-decoder. The integrated receiver-decoder creates a broadcast version of the digital broadcast stream which comprises a broadcast watermark and a video on demand (VOD) version of the digital broadcast stream which comprises a VOD watermark. The integrated receiver-decoder may align the broadcast video with the VOD watermarked audio to ensure proper local storage and subsequent VOD distribution.

Abstract: A diagnostic system for monitoring a status of a CT system includes at least one radiation detector configured to monitor a CT component and generate signals representing measurement data associated with the CT component. The system also includes a diagnostic computer device in communication with the detector. The device is configured to receive an electrical signal from the detector and identify a first frequency in the electrical signal.

The first reference frequency is at least partially indicative of a first mechanical status of the CT component. The device is further configured to determine that the first frequency in the electrical signal is substantially similar to the first reference frequency and, in response, determine that the CT system has the first mechanical status.
