Abstract: A method for detecting and reporting changes in functional features of a simulation model caused by a software revision is disclosed. In one aspect, the method is independent of simulation model architecture. One performs regression testing with a plurality of feature-specific modules. The feature-specific modules are configured to generate a first set of information with the simulation model and compare the first set of information to a second set of corresponding information from the simulation model. In the above-described testing, the first set of information postdates the software revision and the second set of information predates the software revision.

Abstract: An enclosure is disclosed which is highly secure, permits access to a cabled network system only by one user at a time, permits visual and unequivocal observation of the security status of the enclosure, and prevents access to the interior thereof only by authorized persons. The enclosure has back, front and side walls and an interior, with all connections being internal. Limited interior access is provided only through a door and a service opening. Within the enclosure is a system connection device to the system, which is configured for access thereto by only a single user at a time. A lock secures door closure. Thus access to the cabled system through the enclosure is available only to one user at a time and must be obtained through the open door, with usage thereby being visually identifiable, and the door prevents unauthorized access.

Abstract: A speed display device for focusing a motorist's attention on the vehicle's speed, includes a screen which will digitally display thereon the vehicle's radar measured speed in either a first steady state at one color or in a flashing state at a second color. An internal microprocessor compares a preset threshold speed with the vehicle's measured speed. If the measured vehicle's speed is not greater than the threshold speed, the measured speed is screen displayed by energization of a first set of amber lights in a pattern according to the measured speed. If the measured speed is above the threshold speed, a second set of red flashing lights is energized in an accentuated pattern according to the measured speed. The device focuses the motorist's attention on the vehicle speed per se, particularly when above the threshold limit.

Abstract: A digital video surveillance system for a law enforcement vehicle comprises a video camera mounted on the law enforcement vehicle and positioned to view an incident. A memory buffer records video signals from the video camera. A controller generates record and playback signals to record and to display the video signals. A digital video recorder is responsive to the record signal to record the video signals from the memory buffer on an optical medium and to the playback signal to reproduce video signals recorded on the optical medium. A vault encloses the digital video recorder. A battery provides backup power to the digital video surveillance system. The optical medium may be a DVD disk. A watermark may be included with the digital recording.

Abstract: An improved switching system for controlling a radar control unit includes a radar hold switch and lock release switch on a remote control. Depression of the hold switch places the radar in a hold or standby mode. Upon depression and holding of the lock switch tracking of the target vehicle occurs. Upon release of the lock switch the displayed vehicle speed will be locked on the lock window of the radar with the radar unit being placed in a standby mode. A subsequent depression and release of the lock/release switch clears the locked target speed and maintains the unit in a standby mode. Underlying logic utilized by the signal processor analyzes signals corresponding to the positions of the hold and lock switches so as to direct the radar into the appropriate mode.
