Abstract: A dome camera assembly (10) of this invention includes a base housing (12) and a transparent dome (14). A pan motor (18), a tilt motor (20), and a video camera (22), are mounted to a movable platform (24) that is suspended by horizontal and vertical bearings (32, 36) to a platform support ring (26) attached to the base housing. The pan motor is direct-coupled to the platform support ring by a panning drive wheel (28) that pans the video camera through azimuthal angles. The tilt motor is attached to the movable platform and is directly coupled to the video camera for tilting the camera through elevation angles. The pan and tilt motors are mounted in a balanced configuration at opposite sides of the video camera with their drive shafts rotating about a common axis that extends through the center of gravity of the video camera.

Abstract: A method and apparatus for enhancing the operation of computer keyboards. The keyboard includes a plurality of keys, and code generation means for producing make and break codes when keys are depressed and released. The invention comprises a processor coupled to receive the generated codes. The processor detects a sequence of codes serially including a make code of a trigger key, a make code of a target key different from the trigger key, and a break code of the target key. A timer determines whether the interval of time between the trigger key make code and the target key break codes exceeds a predetermined non-zero triggering interval. If the sequence is not detected, or if the triggering interval is not exceeded, then the processor outputs the codes produced by the code generation means. However if the sequence is detected and if the triggering interval is exceeded, modified codes are output.

Abstract: A method and apparatus for enhancing the operation of computer keyboards is disclosed. The invention allows touch-typing of nontouch-type keys by detecting a triggering sequence in the touch-type keys. For example, by holding down the Space Bar while depressing and releasing a second key and before release of the Space Bar, the Space Bar is seen to act as a Control key. Furthermore, the functions of nontouch-type keys may be superimposed upon touch-type keys and accessed in a similar manner. The invention interprets make codes which are generated by the keyboard when a key is depressed and a break code which is generated by the keyboard when a key is released. If a triggering sequence of codes is detected, then the normal function of one of the touch-type keys is altered.
