Abstract: A method of reducing image artifacts in tomographic, projection imaging systems due to periodic motion of the object being imaged includes the acquisition of a signal indicative of the periodic motion. This signal is used to identify a quiescent period in the periodic motion so that the acquisition of projection data may be coordinated to be centered within the quiescent period. The sequence of the angles at which projection data is acquired is controlled so that the primary axis of periodic motion is perpendicular to the axis of projection at the center of the quiescent period. Multiple periodic signals may be coordinated by awaiting their best alignment over a fixed number of cycles of one of the periodic motions.

Abstract: In a data modem receiver (80) the received signal is digitized in an A/D-converter (84), the output of which is applied to notch filter means (88, 96) which eliminates secondary channel signals, and which applies an output signal to a pair of IIR filters (112, 116), responsive to the frequency components present in a training signal. The values of the IIR filter output signals are determined and compared with a pair of threshold levels provided by a threshold setter circuit (152) responsive to the peak received signal level to detect the receipt of a training signal. In response to the detection of a training signal, DFT calculations are initiated for timing recovery and modem address identification, using samples stored in a buffer shift register (206). A gain control circuit (220) is located subsequent to a band-pass filter (212) coupled to the buffer shift register (206).

Abstract: Gradation display is demanded in the display device for binary display by the intensity of electric field, possessing a threshold voltage for display operation, such as liquid crystal display device. Various methods have been proposed to realize this but they have their own problems, such as necessity of advanced high preci­sion machining and requirement of extremely high response speed. In the invention disclosed herein, display electrode and insulation layer are formed on a pair of substrates, and a display layer is placed between insula­tion layers to compose a display device. In this display device, plural display picture elements are set depending on the arrangement state of the display electrodes. In the display picture elements, divisions are set in insualtion layer, and different dielectric constants are set for each division. Therefore, the display device has a different impedance in every division within the display picture element, and the apparent threshold voltage of each division may be varied. As a result, gradations corresponding to the number of divisions within each display picture element may be displayed.

Abstract: A method of compensating for the angular coupling of optical fibers to a tilted facet optoelectronic component (26) involves a precise calculation of the coupling angle with respect to the active layer of the component and with respect to the side walls of the package in which the component is to be mounted. With these angles computed, the tilted facet component is positioned on a carrier (24) at an offset to the perpendicular such that input/output fibers (30,31) can exit the component package perpendicularly to its sidewalls. The component (26) is secured to the carrier (24) by a solder having a high melting point such that subsequent soldering of parts to the carrier will not affect the component positioning. A localized cooling method then allows the sequential alignment and soldering of one optical fiber at a time to the offset tilted facet component, while previously aligned and soldered optical fibers are held fixed. This method utilizes the mechanical property of a sharp melting point eutectic alloy solder or a pure metal solder for the fiber connections and is effective for multi-fiber optoelectronic packages demanding stability and high precision. A package design for tilted facet optoelectronic components requiring multi-fiber alignment incorporates this feature of localized cooling internally. The package utilizing localized cooling method internally eliminates the tilted facet-optical fiber alignment problem, while providing standard lead configurations.

Abstract: The invention relates to a collet chuck for thread cutting with internal coolant feeder. Collet chucks for clamping machining tools in rotating spindles of machine tools are known in which the coolant for the cutters flows through a flexible conduit, e.g. a hose, arranged in the interior of the collet chuck and leakages of the coolant occur. In order to avoid this, the driver (8) containing the collet chuck (13) together with the tool is supported axially in two bearings (32, 37), while maintaining the coolant flow in a main body (2) of the collet chuck, for the purpose of travel compensation between the relatively small advance of the tool spindle (4) and the relatively small pitch of the thread to be cut. The collet chuck can be used even if it is the workpiece which performs the feed motion.

Abstract: An electronic gaming device (10) (e.g., a so-called "videogame" type portable electronic game including a raster scanned liquid crystal display panel (14) and user controls (18)) includes a pseudo-stereo sound generator (58). Plural independent sound generating circuits (541-544) produce audio signals under microcomputer (22) control and the microcomputer (22) may route the outputs of the plural sound generating circuits (541-544) independently to one or the other (or both) of two independent audio channel outputs. Pseudo-stereo sound is thus produced when a stereo headset (64) is used to listen to the sounds produced. A selecting circuit (202) automatically mixes the two audio channel (SO1, SO2) outputs together and provides them in monaural form to an internal loudspeaker (62) when no such stereophonic headset (64) is connected. 
     The microcomputer (22) controls generation of sounds and music in accordance with a musical pitch (frequency) data structure (312), a musical duration data structure (314) and a musical score data structure (316) stored in the interchangeable memory cartridge (16). The musical score data structure (316) specifies pitch and duration in terms of address offsets into the pitch and duration data structures (312, 314). Program control instructions (310) controlling sound generation thus need not explicitly specify the actual control data written to the sound generator (58) to produce musical notes of desired pitches, durations and other characteristics.

Abstract: A computer system 10 employs an apparatus for controllably generating interrupts to the computer system processor 12 in order to correlate a significant event occurring within the computer system to the value stored within the program counter at the time of the significant event. In this manner, the apparatus is useful for diagnosing the performance of the computer system. The apparatus includes at least one pair of 16-bit binary counters 42, 44, each having inputs connected through respective multiplexers 50, 52 to a variety of significant event signals. For example, the computer system 10 typically employs a cache where significant time can be wasted by repeated "misses" within the cache. By selecting the cache "miss" signal to be counted by the 16-bit binary counters 42, 44, a signal is generated approximately every 64,000 "misses." The output of the counters 42, 44 are connected to high priority input ports 30, 32 of the processor 12 so as to generate an interrupt that will ordinarily be handled immediately upon the completion of the current instruction being executed. The software interrupt routine retrieves the instantaneous value of the program counter and places that value within a buffer, which is subsequently written to a file in main memory. Thus, at the completion of the program currently being executed, a file within the main memory contains an incidence chart of the particular instructions that generated the cache "misses."
