    摘要: A parallel architecture matrix algebraic processing system exhibits patterns of arrayed (i) light transmitters and (ii) light receivers that are identical, but at differing scales. Planar arrays of one or more optoelectronic processors--principally semiconductor chips or chip arrays--having both computational and light input/output capabilities optically communicate from one plane to the next through free-space space-invariant optical data distributions--principally lenses and computer-generated holograms--having both replication and distribution capabilities. Each optoelectronic processor, or OP, consists of a number of arrayed optoelectronic processing elements, or OPEs. The OPEs, in turn, typically consist of a number of optoelectronic sub-processing units are preferably electrically interconnected in a tree-based structure, preferably an H-tree. Leaf units include typically one light detector plus local memory, logic circuitry, and electrical input/output. Fanning units typically include local memory, logic circuitry, and electrical input/output. A root unit typically includes electrically-connected local memory, logic circuitry, electrical input/output, and a light transmitter. Vector results of algebraic computations and combinations are flexibly performable in the units of each OPE, and variously optically distributable to other OPEs in successive OPs. The versatile algebraic vector manipulations and vector distributions support primitive functions such as intrinsic and extrinsic vector outer products; operations such as vector-matrix multiplication; and complex systems such as neural networks, fuzzy logic and relational databases. A system of .gtoreq.10.sup.3 fully optically communicating OPEs achieves capacities of 10.sup.6 -10.sup.8 interconnects, and processing speeds of 10.sup.12 interconnects/second.

    摘要: The present invention utilizes the modulation ratio between the flicker of a sensor signal and the absolute signal average to detect fire conditions. The system of the present invention requires that the signal on a sensor channel be above a certain threshold and the ratio of the flickering portion of the signal to the absolute signal average be within a certain range. The system may be applied to any sensor signal in response to any source, including, but not limited to, radiation, acoustic or optical signals including ultraviolet, visible or infrared radiation. Signals may be filtered with a median filter to remove noise. A least-mean-square curve-fit is made to the data to account for any growth or decay in the fire signal. The flicker can be calculated using any of several metrics such as standard deviation, p-norms, or maximum deviation, but mean deviation seems to provide optimal performance. The modulation ratio system can be augmented with a separate detection scheme for large-scale fires. The system can also be modified to allow for increased sensitivity in the case of a previous alarm condition. Multi-channel modulation ratio systems may be configured such that each channel's corresponding ratio and absolute signal average must meet the corresponding requirements before a fire alarm is declared. Multi-channel systems may include a form of cross-thresholding wherein the threshold of one channel is dependent upon the signal levels of the other remaining channels.

In one embodiment, an optical multiplexer/demultiplexer system comprises an optical filter, a first optical isolator in optical communication with one side of the optical filter, a second optical isolator in optical communication with an opposite side of the optical filter, and a light disposer in optical communication with the first optical isolator. In another embodiment, an optical multiplexer/demultiplexer system comprises a first boundary filter, a first transitional optical filter in optical communication with the first boundary filter, a second boundary filter in optical communication with the first transitional optical filter, a second transitional optical filter in optical communication with the second boundary filter, and a third boundary filter in optical communication with the first transitional optical filter. Various optical filtering techniques are disclosed which utilize filters with shifted free spectral ranges, half-band filters, or boundary filtering. These filtering techniques can be used in both multiplexing and demultiplexing methods.
