Abstract: A rail testing system comprises a proximal mobile track system and a distal mobile track system. Each of the proximal mobile track system and the distal mobile track system are movable in a horizontal direction and a vertical direction. A carriage is movably coupled to the proximal mobile track system and the distal mobile track system. The system has a sensor pod comprising a roller search unit. The sensor pod is configured to lock to the carriage for testing of a rail. The system includes a sensor array comprising time of flight sensors. The sensor array is usable to maintain an alignment of the roller search unit with the rail.

Abstract: A roller search unit for detecting rail defects with integrated digital circuitry includes a liquid filled tire mounted to an axle assembly with wheels. An ultrasonic transducer array positioned within a housing is positioned within the within the tire and coupled to the axle. The housing contains transducer interface circuitry operable to receive analog signals from the ultrasonic transducer array and contains digital flaw detection circuitry operable to convert the analog signals to digital signals and perform analysis on the digital signals to detect flaws in a rail. The transducer interface circuitry and digital flaw detection circuitry are configured to stack to provide a compact, small footprint assembly. The conversion of the transducer signals from analog to digital within the tire permits transmission of the digitized data without susceptibility to interference and noise.

Abstract: Systems and methods of environmental parameter determination are provided. A system can include a data processing system to obtain sensor data, apply a data normalization operation to the sensor data to generate a normalized data set for storage in a database, apply at least one filter to the normalized data set to generate a filtered data set, obtain the filtered data set to generate a plurality of performance indices, generate a digital output that corresponds to the performance indices, and provide the digital output to a client computing device for display by the client computing device.

Abstract: This invention is in the field of medicinal chemistry. In particular, the invention relates to a new class of small-molecules having a dimethyl-nonatetraenyl-trimethyl-cyclohexyl structure useful as therapeutics for the treatment of subjects suffering from disorders characterized by abnormal proliferation and/or abnormal differentiation of cells, in particular of cells of which the growth and differentiation is sensitive to the actions of retinoids.

Abstract: Devices, systems and methods are provided for writing, by a plurality of computing resources, to contiguous memory addresses of memory that supports random access, without having to specify actual write addresses of the memory.

Abstract: Systems and methods are provided for performing write-with-response operations in a network on a chip architecture. In response to receiving an instruction to perform a write-with-response operation, a writer computing resource of a computing system (implemented using the network on a chip architecture) executes this instruction by performing a write operation for writing data to a memory location followed by a response operation for notifying a notification target computing resource of the computing system that the data has been written to the memory location.

Abstract: Systems and methods to be used by a processing element from among multiple computing resources of a computing system, where communication between the computing resources is carried out based on network on a chip architecture, to send first data from memory registers of the processing element and second data from memory of the computing system to a destination processing element from among the multiple computing resources, by sending the first data to a memory controller of the memory along with a single appended-read command.
