Abstract: CONSTELLATION MATCHING SYSTEM AND METHOD                   ABSTRACT OF THE DISCLOSURE      A system  (10)  and method for matching a set of detected points (26) to a reference constellation (20). A  programmable  processor   (14)   receives  detected coordinate locations from a sensor (16) and reference coordinate locations from a reference storage device (12).     The  processor  (14)  performs  a  coordinate transformation from the reference coordinate frame to the detected  coordinate  frame  and  contructs  a  table  of possible matches.  Potential matches are found from the possible matches which have their difference vectors below a predefined threshold.  These possible matches are then placed in a match matrix histogram (30) which is further refined to eliminate all but the best matches. The final matching then may be used to find a particular aimpoint (24) in the detected constellation (26).

Filed: 1992-01-23
Abstract: ABSTRACT OF THE DISCLOSURE    The apparatus for analyzing particles classifies or counts components in sample liquid by image processing, by passing a liquid sample of urine or the like in a flattened flow.  This apparatus for analyzing particles comprises sheath liquid supply means (21), sample liquid discharge means (18), temperature sensor (36) for detecting the ambient temeprature, temperature measuring circuit (38) for measuring the temperature depending on the changes of the temperature sensor, and driving circuit (34) for driving the sample liquid discharge means by correcting the sample liquid discharge flow rate depending on the signal from the temperature measuring circuit.    Moreover, the sheath liquid is supplied at a specific pressure, and the sample liquid discharge quantity is corrected depending on the ambient temperature.  When changed to the high scale factor taking state or low scale factor taking state, a different correction rate is set.    Thus, if the environmental conditions such as temperature should vary, the sample liquid volume is kept constant, so that particles may be analyzed at high precision.

Abstract: Apparatus and methods for adjusting the video display controls in a multi-frequency video display include an EEPROM that stores multiple sets of video display parameters for the video display. A microcontroller receives input from a user, changes the stored display parameters and outputs changes in the parameters to the video display. The microcontroller also controls video display apparatus that displays on-screen menus and value indicator graphs for facilitating user input. The video display apparatus incorporates a video clock synchronized to the horizontal synchronization signal of the multi-frequency display, to keep the displayed menus synchronized regardless of the current frequency. In addition, the video display apparatus elongates displayed characters at higher frequencies to control the absolute size of displayed characters across frequencies. The present invention provides for changes to video display parameters, and for resetting the display parameters to factory standards, without manipulating electromechanical devices such as potentiometers.

Abstract: ABSTRACT       A loudspeaker  system  having  the  ability  to uniformly direct high-frequency as well as low-frequency sound hemispherically is described.  The acoustical centers of a low-frequency and a high-frequency driver are aligned in space to provide a common source of sound to be   directed   through   a   common   sound-guiding structure.
