    摘要： Aspects of the subject disclosure may include, for example, receiving a request for media content, the media content being divided into a plurality of chunks, obtaining information about the chunks and constraints, determining whether there is a remaining layer to be downloaded, in response to determining that there is a remaining layer to be downloaded, determining a list of chunks that can be downloaded at a current layer and a downloading schedule according to the list of chunks that can be downloaded at the current layer, in response to determining that there is no remaining layer to be downloaded, producing a composite schedule for downloading the media content, and downloading the media content according to the composite schedule. Other embodiments are disclosed.

    摘要： A method for overpressure control in a hydraulic system having multiple hydraulic pumps, with each hydraulic pump being connected by a respective hydraulic circuit for actuating a single respective hydraulic actuator, includes actuating a first variable displacement hydraulic pump, the first hydraulic pump being fluidly linked by a first hydraulic circuit to a first hydraulic actuator for powering the first hydraulic actuator. Upon detecting a pressure that exceeds a predetermined threshold pressure, the flow rate of the first hydraulic pump is electronically modified to a second flow rate lower than the first flow rate whereby the pressure in the first hydraulic circuit is reduced to a pressure that is below the predetermined threshold pressure.

    摘要： A circuit includes an input block and a combinational logic block. The input block has reconfigurable latches that are connected serially during testing times such that an output of one of the latches is connected to an input of a successive latch. The latches are directly connected to first level gates of the combinational logic block. The combinational logic block contains switches that prevent the propagation of signals through the combinational logic block during testing times other than when a desired vector is loaded into the latches. The switches disconnect the power and/or ground from the first level gates. The switches further connect the outputs of the first level gates to power or ground, depending on the type of transistors used in the first level gates. The switches alternatively delay the output through a pair of inverters and resupply the output to itself if refreshing the output is desired.
