Abstract: A monitoring system and method may receive detection times at which passage of one or more vehicle systems by a detection device disposed along a route is detected. Locations of the one or more vehicle systems at different times may be received from one or more location sensors disposed onboard the one or more vehicle systems. The locations of the one or more vehicle systems when the one or more vehicle systems were detected by the detection device may be determined by comparing the detection times with the different times associated with the locations. A condition or state of the detection device can be determined by comparing the locations that are determined by the controller with a device location of the detection device.

Abstract: A semiconductor optical amplifier (SOA) with a variable optical confinement factor I? along the length of the device is disclosed. At the input end of the SOA, the optical confinement is high as an optical core is adjacent an optical gain layer, resulting in a high-gain region that rapidly increases the optical signal power. In the central portion of the SOA, the optical confinement is continuously reduced as the optical core is tapered away from the optical gain layer, thereby lowering the gain, but increasing the output saturation power. Near the output end of the SOA, the optical confinement factor is held constant, providing a length of additional gain, thereby further increasing the output power. The SOA may optionally include a spot-size converter region to focus the output optical signal.

Abstract: Methods, systems, and non-transitory computer readable storage media are disclosed for optimizing computer memory usage for lookup lists in computer memory via probabilistic data structures. For example, the disclosed system generates a probabilistic data structure (e.g., a Bloom filter) to represent data in a lookup list including multi-token items by hashing items of the lookup list to sets of bit values in a bit vector. The disclosed system classifies text content in a digital document by utilizing a maximum number of tokens from multi-token items in the lookup list to select and compare sets of sequential tokens in the digital document to the probabilistic data structure. The disclosed system also iteratively reduces the number of tokens in sets of sequential tokens for subsequent comparisons. Furthermore, in some aspects, the disclosed system causes a computing device to modify a digital document and/or database operations based on the classifications.
