Abstract: A system for tolerating a single event fault in an electronic circuit is disclosed. The system includes a main processor, a fault detection processor responsive to the main processor, the fault detection processor further comprising a voter logic circuit, three or more logic devices responsive to the fault detection processor, each output of the three or more logic devices passing through the voter logic circuit, and a programmable error filter. An output of the voter logic circuit is coupled to the programmable error filter.

Abstract: An instrument comprises first and second modules. The modules each comprise computer electronics hardware including a display screen typically carried by the first module. The modules are separable from each other. One of the modules has a projecting bus for connection with the interior of the other module. The bus defines a plurality of sockets for removably receiving circuit boards of desired variable types for direct connection with electronics within the other module and for connection with electronics of the one module through the bus. Thus, the instrument is easily modified in its functioning by addition, subtraction, or replacement of circuit boards from the bus.

Abstract: A care management workstation unit which contains three basic elements. There is a cathode ray tube or CRT, a mount, and a system unit. The CRT is rotatably mounted on the mount. It is capable of any rotational position and is able to be balanced at all such positions. The CRT is unique in that it is integral to the system. The mount connects the CRT to the system unit. It is able to be mounted flush against a wall such that the entire unit is supported by the mount. The system unit is also flush with the wall and the wall mount so that the entire system may be placed for mounting against a wall. In all, these three devices combine into one system to provide for a powerful, compact and ergonomically successful device which enables one to use the system virtually anywhere within a hospital or industrial setting.
