Abstract: An overlay projection apparatus for aiding in the communication of graphic presentations to large audiences by enabling the on-screen writing of overlay icons, highlighting bars and alpha-numeric labels as selected by the presenter. Brightness and color control of overlay highlighting graphics provide audience visual comfort over a wide variation of projected underlay graphic and ambient light conditions. Digital formation of overlay graphics by presenter/lecturer touch control command from a remote video panel also enables total storage and recall of multiple frames of complex overlay graphics with matching underlay graphics for reemphasis or for question and answer sessions between the lecturer and audience.

Abstract: A wire insertion guide may be used with a wide variety of closed barrel electrical contacts. The wire insertion guide includes a housing, a movable funnel located within the housing, a fixed funnel nested within the movable funnel, and a contact holder mounted in spaced relation with the movable funnel.The wire insertion guide is used in concert with a crimper assembly, but is a separate apparatus, and may be used with a wide variety of crimper assemblies either of the manual or automatic type.

Abstract: A contact crimping machine for use with a pin having a wire receiving seat includes a chamber, a plurality of crimping dies and actuating means for activating the crimping dies. Means are provided selectively to move one of the pins through the chamber into communication with the crimping dies, and restraining means are provided for maintaining a pin in suspended position removed from the actuating means. The contact crimping machine is constructed so that when the pre-stripped end of a wire is placed into the wire receiving seat of a pin, and downward pressure is supplied, the pin engages the actuating means and the crimping dies are momentarily urged against the wire receiving seat thus crimping the pre-stripped end of the wire within the wire receiving seat. Circuit means are provided to automatically position the next pin into place.

Abstract: Method and apparatus are provided for the determination of the Raylographic information of a body part which is ensonified by acoustical energy pulses by a particularly precisely focused acoustical focusing system to produce acoustical energy echo pulses which are detected in coherent manner. Fourier transformation of the pulses from the time to the frequency domain enables frequency domain deconvolution to provide the impulse response with minimization of mathematical instabilities and distortion of the frequency domain impulse response. Noise extraction and spatial deconvolution filtering are included to respectively maximize signal to noise ratio and minimize distortive effects of body part surface non-orthogonality and combine with the above to provide for particular stability in the overall results and attendant increase in the axial resolution of Raylographic display and in the overall resolution of body part image displays.
