An electronic lighted safety marker system used by emergency responders to warn motorists of the presence of an accident scene ahead on or beside the roadway is provided by the invention. Such safety marker can be deployed individually or in groups by the emergency responder along the perimeter of the accident scene and ideally ahead of it along the roadway to provide adequate warning to approaching motorists to avoid the accident scene. The safety marker contains a power source, a light panel, a protective shield for the light panel, and electronic circuitry for controlling the operation of the lights in a predetermined frequency or pattern, and may be automatically actuated and self-righting when it is dropped onto the ground or other hard surface. The safety marker further includes a transmitter for sending a signal to a receiver. Upon impact with the safety marker, the signal ceases and the receiver, equipped with an alarm, triggers either or both of an audible or visual signal. The safety marker can also contain an incursion warning system against incoming vehicles, an early warning radar transponder for sending a warning message to such incoming vehicles, a GPS location detector and transmitter for providing the location of the safety marker and its associated accident scene to a central dispatcher, and a gunshot sensor for detecting the occurrence of gunfire around the accident scene and its location to provide that information to the central dispatcher.

A processor unit for a multipoint audio-video conferencing system, wherein the processor unit includes a host processor for controlling operation of the audio-video conferencing system. Controlling operation includes controlling the performance of a plurality of functions associated with servicing each of a plurality of communications connections, each of the connections being between a conferee terminal and the audio-video conferencing system. The processor unit also includes a plurality of digital signal processors, in communication with each other over a first bus and in communication with and controlled by the host processor over a second bus. Each digital signal processor includes an associated configuration element for adaptively configuring a selected digital signal processor to perform processing required by a selected one of the functions associated with servicing a selected one of the communications connections. The processing required by the conferencing functions is distributed between the plurality of digital signal processors.

Audio-video conferencing system

An improved system for connecting and processing a plurality of phone user in a teleconference on a common digital bus. The apparatus includes a plurality of digital processing units (DSPs) associated with selective phone lines and in communication with each other. Each DSP determines an activity status for each associated phone line and transmits that status to the other DSPs, The DSPs create and update respective identical 'talk-lists' which reflect the active conferees whose voice data is currently being output on the phone channels. The system thus provides scaleable teleconferencing in a real-time configuration without switching between the various signals on the common bus such that each incoming caller or even a plurality of conferences has equal priority.

A man-machine interface for use with industrial processes is disclosed having the capability of design and configuration of the interrelationship of components forming an overall industrial process. The man-machine interface further provides operator use, including process monitoring and control, as well as alarm annunciation. Most user interaction with the man-machine interface is performed through a color CRT monitor having a touch panel on the surface of the CRT screen. Operator use may be limited to touch panel interaction while configurer and designer use normally further includes use of a keyboard. The man-machine interface utilizes distributed processing and incorporates a high level graphic language. The graphic language facilitates real time graphic display implementation through use of dynamic and static variables. Variable types are dynamically associated with variable values so that variables can undergo type changes without detrimental effect. Video bit bangers and shifters further enhance the versatility and ease of implementing rapid modifications of graphic displays. The man-machine interface further incorporates a new bus structure including a new bus arbitration technique, a unidirectional memory boundary protection mechanism, an improved interrupt system, and an improved watchdog timer circuit.

A data communication system is disclosed that utilizes a synchronized serial bus for communication between multiple stations connected to the bus. A token is employed such that when owned by a station it allows that station to transmit high level messages over the bus and command other stations to transmit high level messages to it if required by the token owner. Fundamental events called primitives are perceived by stations. Each station capable of token ownership embodies the same set of rules, the rules in turn defining the circumstances when perceived events cause a station to change from one state to another. Fundamental sets of rules, or modules, are used in the communication system to achieve a system for the automatic generation of a token list of stations with periodic ownership of the token, as well as for expansion or contraction of this token list. In addition, automatic change in the token pass handshake protocol is described. The communication system allows bus interconnection to stations having no potential token access, with communication control provided by master stations which have token ownership capability.
