Abstract: A method and system for fusing image data includes an electronic circuit (L) for synchronizing image frames. An adaptive lookup table unit (302a, 302b) receives the image frame data sets and applies correction factors to individual pixels. The size of an image is then scaled or otherwise manipulated as desired by data formatting processors (312a and 312b). Multiple images communicated within parallel circuit branches (P1 and P2) are aligned and registered together with sub-pixel resolution.

Abstract: A system and method for combining image data are disclosed. Sensor data sets (210, 212) are received from sensors (112). An image metric (214) with slots (217) is generated by repeating the following for each sensor data set (210, 212) until a final slot (217) of the image metric (214) is reached: generating display data from a subset of a sensor data set (210) for a slot (217) of the image metric, and generating display data from a subset of a next sensor data set (212) for a next slot (217) of the image metric (214). An image generated from the image metric (214) is displayed.

Spectral detectors detect energy of the light proximate each image sensor, and a voltage value corresponding to the detected energy is determined. A weight factor for each image sensor is calculated according to the voltage value. The image sensor data from each image sensor is weighted according to the weight factor for the image sensor, and the weighted image sensor data are fused.

Abstract: A spool (12), for supporting a fiber optic coil (14) and a shield (118) surrounding the spool and fiber optic coil, includes a centrally placed, bolt-receiving opening (29). The shield includes a lower shield portion (20), which supports the spool and the fiber optic coil, and an upper shield portion (118). The upper and lower shield portions are arranged to interfit with each other at an interface (121).

A bolt (156) has a head (156a), a shank (156b) and a threaded end (156c, 156d). The bolt head is engageable with the spool through intermediary structure (48). The shank is insertable through the centrally placed, bolt-receiving opening (29) and the lower shield opening (26), for radially centering the assembly and its components. The threaded end is disposed to engage a threaded opening (68) in a gyroscope assembly support (66).

A dam network (34) is formed about the bumps (30) to prevent undesired spreading of the conductive material (28). Bonding material (36) between the surfaces (38a and 38b) of the substrates (10 and 12) bonds the multiple layers. The bonding material (36) has apertures through which the solder bumps (30) are connected.

Abstract: A method for attitude alignment of a slave inertial measurement system connected to a rotationally mobile platform supported by a vehicle that is stationary relative to a reference navigation frame comprises the steps of mounting a master reference inertial measurement system on the rotationally mobile platform and determining a master reference system attitude using measurements of acceleration and angular rates of the master reference inertial measurement system relative to the reference navigation frame. A slave system attitude is determined using measurements of acceleration and angular rates of the slave inertial measurement system relative to a slave system navigation reference frame and comparing the slave system attitude to the master reference system attitude to determine an attitude difference. The attitude difference is processed to obtain a correction to the slave system attitude.

Abstract: An InGaAs Image Intensifier (“I2”) Camera (C) detects and forms an image (310) to be viewed. An InGaAs photocathode Image Intensifier (312) is used to pass an amplified signal (316) from a screen (320). The InGaAs image intensification tube (312) is optically coupled (328) to an imaging device (322) for passing output light. The output light (316) from the InGaAs tube (312) is transformed by an electronic circuit (322) producing a desired signal output (324). The signal output (324) from the electronic circuit (322) may be further enhanced into an enhanced signal output (310). The enhanced signal output may be formatted into a form for viewing or may be saved.

Abstract: The present invention provides a multilayered circuit board that can be used in high-density and high-speed electronic applications.

Abstract: The present invention is directed to a high density electrical connector which can provide 80 or more twinax connections per linear inch in a 20 millimeter card slot. In a typical electronic system package, 20 millimeters is the spacing from center line to center line of the adjacent parallel daughtercards. Twinax cable is coaxial cable that contains two .inner conducting wires rather than one. The two inner conducting wires provide two physical channels. Coaxial cable is called “coaxial” because it includes one physical channel that carries the signal surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis. The outer channel serves as ground.

The distance between the signal via in the first signal pad and the signal via in the second signal pad is greater than the distance between the contact section of the first signal pad and contact section of the second signal pad.
