    Abstract: Systems and methods for non-intrusive program tracing of a device are disclosed. The methods involve generating a program trace signal from at least one of power consumption and electromagnetic emission of the device; digitizing and decomposing the program trace signal into at least two digital program trace component signals including a low frequency program trace component and one or more high frequency program trace component signals; classifying fragments of the at least two digital program trace component signals of the program trace signal as at least one of a known portion of program code and an observed behavior of the device. Each of the at least two digital program trace component signals have different frequency bands and the bandwidth of each program trace component signal is smaller than the bandwidth of the program trace signal. Each of the high frequency program trace component signals include an envelope.

    Abstract: A rotary drive includes a housing; a shaft rotatably mounted within the housing and rotatable about a drive axis; a passage internal the housing and extending circumferentially about the shaft; a stator vane within the passage; and a rotor vane within the passage. The stator and rotor vanes are movable between respective closed positions in which the stator and rotor vanes separate the passage into a circumferentially expanding chamber in fluid communication with an inlet in the housing and a circumferentially collapsing chamber in fluid communication with an outlet in the housing, and respective open positions in which the rotor vane is movable circumferentially past the stator vane during rotation of the shaft.

    Abstract: There is provided a frozen food product, such as frozen juice, and the method of providing same. This involves cooling the food product, such as a juice, to a slurry temperature within a freezing temperature range for the juice to provide a slurry, the juice slurry comprising a liquid juice component and a frozen juice component; providing the juice slurry to a container; and freezing the juice slurry within the container.

    Abstract: Systems and methods are provided for operating a media transmission network. The system includes at least one destination device for receiving a plurality of media streams from a plurality of source devices. The system further includes a controller that is configured to, for each media stream of the plurality of media streams: determine a media property adjustment for the media stream based at least on the media stream; identify a source device from the plurality of source devices associated with generating the media stream; determine at least one device setting for the identified source device to apply the media property adjustment to the media stream; generate a control packet for configuring the identified source device based on the at least one device setting, the control packet including the at least one device setting; and transmit the control packet to the identified source device.
