Abstract: The present disclosure provides methods and systems for stochastic optimization of a robust inference problem using a sampling device.

Abstract: A refrigeration control apparatus comprises a master unit with a mother board. The mother board comprises a bus configured to carry signals between boards coupled to the mother board. A processor board interfaced to the mother board is provided. The processor board comprises a processor, and a program memory where instructions for the processor are stored on the program memory. An interface circuit coupled to the mother board is provided. A load control module interfaced to the mother board is provided, wherein the load control module comprises an interface circuit coupled to the mother board, and a circuit breaker coupled to a power input. A load relay comprising a first interlocked relay and a second interlocked relay coupled to the circuit breaker is provided. The load relay is configured to switch power. An override switch and the processor coupled to the load relay to control the load relay is provided.

Abstract: An adaptive canceller filter module having signal sensors and signal filters in a circuit for use with filtered-x algorithms to adapt the coefficients of one of said filters to minimize the measure of the error.

Abstract: An apparatus and method of actively cancelling undesirable acoustic noise generated by a patient diagnosing apparatus during a diagnosis operation which includes a remotely located active noise cancellation unit. The undesirable acoustic noise is transferred via hollow tubes from the patient diagnosing apparatus to the remote location to be detected thereat. A control unit thereafter generates cancellation waves based upon the detected undesirable acoustic noise. The cancellation waves are transferred to the patient area via additional hollow tubes to cancel the undesirable acoustic noise. The use of hollow tubes of non-magnetic, non-metallic material ensures that the undesirable acoustic noise and the cancellation waves do not interfere with the diagnosis of operation.

Abstract: An elongate element such as a length of nylon cord or fiber optic cable is provided with means attached to at least one of its ends and operable to rotate or otherwise move the same. The moving elongate element is illuminated by illuminating means operable to vary the color of illuminating light either independently of, or in dependence on, the speed of movement of the said elongate element thereby to obtain a constant or varying visual effect.
