Abstract: An X-ray detector comprises a detector panel (100) comprising a surface with a plurality of detector pixels, wherein the detector pixels are configured to convert received X-rays into electric signals representative of values indicative of the received X-rays. A data interface (308) transmits images having a fixed number of output pixels. A control unit controls to set (401) a region of interest comprising at least a subset of the plurality of detector pixels, wherein a number of detector pixels in the region of interest is independent of the number of output pixels. The control unit maps (403) the region of interest onto an output image having the fixed number of output pixels. The control unit resamples (404) the detector pixels within the region of interest to obtain values for the output pixels of the output image, and transmits (405) the output image via the data interface.

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: The invention is a mechanism for mounting a film shutter and assembly to a conveyor in a motion film projector, the film shutter assembly including a shutter secured to a mounting bracket, which houses a pair of trucks. Preferably, the mounting bracket securely houses a first truck and slidably houses a second truck to accommodate for the trucks passing over straight and curved portions of the truck, or shutter path. The trucks are rigidly clamped to the conveyor. This configuration permits the shutter to be stably coupled to the conveyor while permitting the shutter assembly to travel along both straight and curved paths. The trucks are generally configured to ride in a raceway, which supports the trucks and maintains the trucks on a predetermined truck path. In one embodiment, the trucks include rollers, which roll along an elongated channel formed in the raceway. According to another embodiment, the trucks include air bearings for carrying the truck along a pressurized raceway.

Abstract: A system and method are disclosed for transporting film in a motion film projector. The system includes a set of film carriages and a set of secondary shutters mounted on a conveyor, which continually advances the film carriages and the secondary shutters along a linear path oriented orthogonally with respect to an optical axis of a aperture block, through which images on the film are projected. Each film carriage receives a loop of film and then rolls the loop of film in the direction of the aperture block. A deceleration mechanism periodically engages and decelerates the film. Once the film has been decelerated, a section of the film is temporarily secured in alignment with the aperture block and an image disposed on the film is projected. The conveyor then moves a secondary shutter into alignment with the aperture block to shutter the aperture block.

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.

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.
