Abstract: A flag assembly for presentation of at least one electrically-powered entity identifying source. The flag assembly includes a pole, a piece of material attached to the pole, and at least one electrically-powered entity identifying indicia within the assembly.

Abstract: Apparatus is directed to a personal, portable alarm system that interfaces with an individual's portable radio and remote speaker/microphone to provide the individual with an audible indication that a radio signal has been received from a remote sensor that is indicative of an event being detected adjacent to the location of the remote sensor.

Abstract: An ultrasound visualization system, and certain aspects of the electronics that are incorporated therein. A scan conversion system which includes means for converting the ultrasound scan signal into a stream of single bit digital data in which each bit is indicative of the relative amplitude of the ultrasound scan signal as compared to the amplitude indicated by previously converted digital data. The single bit digital data is inputted and stored alternately into two full screen buffers. As the data is read into one of the two full screen buffers, the stored data in the other buffer is being simultaneously converted into an analog television video signal. The digital to analog conversion is accomplished by varying an analog television video signal in response to the relative amplitude indicated by each bit in comparison with the amplitude indicated by previously converted digital data.
