A spare voice channel on a cockpit voice recorder (CVR) is used to record flight data. Data from an accelerometer and other sensors in an aircraft are digitized and collected by a microprocessor once each second and are collated and arranged in an industry standard format, and an encoder converts the formatted data into an industry standard code for recording on the CVR. During transmission of data to the CVR, fresh data is collected for the next transmission.
The present invention is directed to recording changes associated with the acceleration of a structure. An exemplary embodiment includes an accelerometer array having at least one silicon beam type accelerometer, a nonvolatile memory, a clock timer, a programmable control unit operatively coupled to the accelerometer array, at least one non-volatile memory, and clock timer. The accelerometer array, the at least one non-volatile memory, the clock timer and the programmable control unit can be formed on a common semiconductor substrate (e.g., integrated), with the accelerometer array disposed in a central region.
A multifunction remote controlled video recording, transmission and playback system includes a still frame generator adapted for selecting and generating still frames on the fly while a full motion video signal is being recorded, without interrupting the recording function. Audio and data signals, such as cockpit audio in an aircraft and gps and telemetry signals may also be incorporated in the recorded full motion video recording on a real time synchronized basis. The still frames are digitally enhanced, producing a full field frame from the analog video signal. Still frames can be produced in single, burst and snap modes without interrupting the full motion video recording function.
A security and surveillance system for aircraft on the ground incorporates a plurality of strategically spaced sensors including video imaging generators, audio sensors, motion detectors, and fire and smoke detectors for monitoring critical components and critical areas of both the interior and the exterior of the a commercial transport such as an aircraft. The system is a comprehensive multi-media safety, tracking and/or surveillance system, which provides both visual and/or audio information as well as critical data such as location, direction, intrusion, fire and/or smoke detection and/or status of environmental conditions and/or asset systems status. The collected information is analyzed and prioritized according to type of event, location and nature of required response for automatically dispatching the proper response. The captured data and images are transmitted to a ground based security station for display on a monitor and may be recorded on a "black box" recorder as well as on a ground based recording system.
A data collection and distribution system for monitoring aircraft in flight, on the ground and at the gate or terminal for monitoring critical and catastrophic events, managing the emergency during such an event, and for investigating the event. The system generates, transmits and collects critical data generated by monitoring equipment onboard an aircraft or other commercial transport and selectively displays the data on a cockpit display console as well as for downloading, transmitting and displaying data at external monitoring and response stations, including fixed ground stations, roving ground stations and chase aircraft or vehicles. Digital surveillance information is collected, processed, dispatched, and log via remote control and access. The system includes a variety of system appliances such as surveillance cameras, sensors, detectors, and panic buttons and accommodates legacy equipment. Within the commercial transport, the system maybe hardwired or may use wireless transmission and receiving systems.
