Abstract: The present application is directed to a video-based motion extraction system that uses mmWave imaging. In one example, an object velocity is extracted in real time from at least one motion vector obtained from a compressed video. The velocity information is combined with distance information obtained from a distance sensor. The combination of distance and velocity is used to calculate a position of the object at each time instance. A velocity profile may be generated. The velocity profile may then be used to reconstruct an image of an object passing in front of an mmWave antenna array.

The encapsulated sensor systems and/or valve controllers can be used to detect fluid levels in a contained system and control valves to adjust the fluid levels in the contained system to a desired level.

Abstract: A machine is cleaned by directing a foam detergent into the machine to remove contaminants from inside the machine. An effluent portion of the foam detergent exits from the machine with some of the contaminants. One or more of a turbidity, a salinity, an amount of total dissolved solids, or a concentration of the contaminants in the effluent is measured. A cleaning time period during which the foam detergent is to be directed into the machine is determined based on the turbidity, the salinity, the amount of total dissolved solids, and/or the contaminant concentration that is measured from the effluent. The foam detergent continues to be directed into the machine during the cleaning time period, and the flow of the foam detergent into the machine is terminated on expiration of the time period.

Abstract: A computer implemented method handles object references. A computer system determines whether an object reference fetched by a load instruction has an expected value for heap protection for a heap in response to receiving the load instruction for execution. The computer system generates an event in response to the object reference not being the expected value, wherein the event is used to manage the object reference. According to other illustrative embodiments, a computer system and a computer program product for managing object references are provided. As a result, the illustrative embodiments can prevent a load instruction from loading an invalid object reference that does not point to a memory location in a heap.
