A photodetector array for sensing radiant energy is described incorporating photodetectors, a respective semiconductor region for holding charge and two transistors coupled in series at each pixel, and a column load transistor. An amplifier at the load transistor may provide gain while providing dynamic range compression and a reduction in signal noise due to resetting of the voltage at the semiconductor regions. The invention overcomes the problem of CMOS manufacturing of photodetector arrays a...

A furnace gas injection apparatus and process for delivering gaseous fuel to a furnace at a compound angle wherein one angle .alpha. of the compound angle is directed outwardly from the furnace burner centerline at an angle of between 75.degree. and 120.degree. to a line extending radially from the furnace burner centerline to the gas discharge openings of the gas injection means.

An inkjet array for a printer includes a number of elements. Each element has an ink chamber and an ink provider, and a piezo-actuator rigidly secured to one side of the ink chamber. The ink chamber is brought into motion in response to an image signal whereby an ink droplet is ejected from a nozzle of the ink chamber. Each of the ink chambers of the array can be brought into motion separately.

In a photodiode array suitable for use in an x-ray detector for computed tomography, the influences of direct conversion of x-rays into contributions to the electrical output signal and optical cross-talk between channels in the photodiode array are significantly reduced by integrating a number of extraction diodes into the photodiode array, with one extraction diode disposed between each two neighboring photodiodes. The anodes of all of the extraction diodes are connected together at a common a...

A hydrophone array to perform passive and active sound imaging is described. The array is comprised of a plurality of acoustic transducers attached to a cable that may be towed behind a geophysical survey vessel. The cable and acoustic transducers are enclosed within a sheath of essentially constant external dimensions, which extends longitudinally the length of the cable and which is effective in minimizing turbulent noise created by the array during its use. The sheath may be circular or ellip...

A switch network is included for connecting each of the I/O paths 136 t...

A hydroelectric power generating module comprises an upper housing section and a lower base section connected to the upper housing. The upper housing has a plurality of generators situated therewithin, and the lower base has a plurality of water flow paths extending therethrough. Each water flow path comprises an upstream water inlet, a downstream draft tube, and a distributor disposed intermediate the draft tube and the water inlet. The water inlets are defined by a plurality of horizontal memb...

An array of processing elements can incorporate a degree of redundancy. Specifically, the array includes one or more spare, or redundant, rows of array elements, in addition to the number required to implement the intended function or functions of the device. If a defect occurs in one of the processors in the device, then the entire row which includes that defective processor is not used, and is replaced by a spare row.

An LED array includes a plurality of first and second light-emitting rows. Each of the first light-emitting rows is composed of a plurality of red and green LEDs arranged linearly alternately. Each of the second light-emitting rows is composed of a plurality of green and blue LEDs arranged linearly alternately. The first and second light-emitting rows are parallel to each other and arranged alternately. Thus, the LED array can generate preferably equable arrangement of colored light to output pr...

A sensor array designed to be continuously indexed through a compatible blood glucose test monitor for the purpose of conducting multiple consecutive blood glucose measurements. The sensor array can be configured to substantially conform to a non-planar surface. In one embodiment, the sensor array includes first and second test sensors which are hingedly coupled together through a pin and socket interconnection. In another embodiment, the sensor array includes a unitary, non-conductive substrate...
