Abstract: The anti-blooming structure of an image sensor is supplied with varying voltages during different integration periods such that charges generated in response to low level light are fully captured, whereas charges generated in response to a bright light spill over in a controlled manner. Accordingly, sensor's response may be generated to result in higher gains at low light levels and progressively lower gains at the higher light levels.

Abstract: A system for detecting and analyzing electrical activity in the anatomy of an organism underlying an electrode array provides signals corresponding to electrical activity adjacent each electrode. Such signals are correlated to the underlying anatomy of the organism and representative outputs presented through various types of output devices. Such outputs may include variations in coloration or other qualities in correspondence with representations of underlying anatomical structures. The system includes novel electrode structures (200, 224, and 284) and methods for producing and attaching electrode arrays (240 and 280) to the organism. The exemplary form of the invention is used in connection with the diagnosis of muscle activity in the lower lumbar regions of humans. Levels of muscle activity detected are analyzed by correlation with the muscular structures underlying the electrode array. Forms of the invention may be used in other applications.

Abstract: A preferred embodiment of this invention is illustrated in FIG. 4 showing an offset and tilted object transducer 50 being rotated about a system axis 51 to sequentially insonify the object from various acute incident angles .theta. to the system axis to provide images of the out-of-focus structures at spaced locations at the hologram detection surface 18 at different spaced times. If the pulse rate of the object transducer is greater than the fusion of the eye, the eye is able to average two or more images into a single perceived image. Likewise, video equipment that receives images at a rate greater than 30 Hertz will average two or more images and display the image at a rate of approximately 30 Hertz. Additionally, external video processing may be utilized to electronically average two or more images electronically to obtain an averaged image at any time constant desired by the operator.

Abstract: The description details a preferred embodiment of an improved large area ultrasonic transducer 70 capable of reducing the generation of adverse "edge effect" waves. The transducer has a thin piezoelectric wafer 72 that has a high area-to-thickness ratio of preferably between 30 and 300. A front electrode coating 84 is deposited on the front surface 74, over the front edge 77, along the side surface 82 and over the back edge 78 and onto a border of the back surface 76 to minimize the application of a voltage potential along the side surface.A voltage modifying layer 92 is placed on the back surface 76 along the back edge 78 for further minimizing the generation of "edge effect" waves. The layer 92 varies in thickness to progressively decrease the voltage applied to the back surface 76 from a large central area 79(a) to the back edge 78. The layer 92 is preferably composed of a non-piezoelectric dielectric material.

Preferably, the velocity of the ultrasonic sound through homogenous plastic material is less than twice that of water. One or both of the concave surfaces 108 and 110 have surfaces that are without a constant radius and curvature, but however are composed of separate radius of curvatures for each small increment of lens surface to properly focus the ultrasound at a desired focal length "L".An alternate embodiment is illustrated in FIG.

Abstract: An image-forming composite image member and subtractive photo process employing that composite, in which composite, a spectrally reflective light-blocking layer, a secondary thin optically functional layer and a subtractive photosensitive layer are carried on a base in an association, in which the reflective layer and the secondary layer cooperate after imagewise exposure and development to define an image member in which the secondary layer and reflector layer may provide a guide to orientation of the composite and may provide a unique polarity-reversing ability to display both a negative and a positive image. In a preferred form, the reflective and secondary layers provide superior uniform light-blocking with a minimum combined thickness, and also cooperate in the photo process during the development to insure rapid and complete clearing of areas with at most minimal mechanical action under portions of the photosensitive layer which are soluble after imagewise exposure and have been removed in development.
