Abstract: A single memory space of a device having a dedicated functionality is dynamically partitioned to provide separate memory partitions for access by different processes along a production stream. Firmware in the device that controls the overall functionality of the device also controls partitioning of the memory space. The firmware also controls how each of the partitions may be accessed. The firmware includes a number of different safety features for protecting data in the device and applies each of the safety features utilized by the device to each of the memory partitions. Data security is implemented independently for each partition in order to maintain functional safety compliance of the device. The different partitions can be created and accessed at different points in a production stream by different entities such as a device manufacturer, its customers and suppliers or other entities along the supply chain.

Abstract: Systems and methods of transcoding video sequences for delivery in a mobile network. A source video sequence including source video frames is received and a source video frame type associated with each of the source video frames is determined based on a differential between a composition time stamp (CTS) and a decoding time stamp (DTS) associated with each of the source video frames. A frame type ratio value for the target frame-types is calculated based on a longest mini-GOP length. A target frame size of each target video frame is determined based on the frame type ratio value and a target transcoding rate, and each of the target video frames in a target video track is encoded to the target frame size to form a target video sequence.

Conductive yarn may also be soldered or otherwise coupled to electrical components.

Abstract: Systems and methods are described herein for adaptively transcoding media in a communications network such that computer processing resources are effectively utilized to deal with varying traffic patterns in the communications network. A computing device receives a request to transcode content and determines a first amount of tokens based on a number of CPU cores associated with the computing device, and a currently used amount of tokens. The computing device determines a second amount of tokens associated with transcoding the content and when the first amount of tokens is less than the second amount of tokens, the computing device bypasses transcoding for the content or adjusts a transcoding parameter to reduce a number of tokens associated with transcoding the content.

Abstract: A MEMS system has an input for receiving a plurality of frequency division multiplexed variable capacitance signals, and a readout node electrically coupled with the input. Each variable capacitance signal is produced by a variable capacitor and has data relating to movement of microstructure associated with that variable capacitor. Moreover, each variable capacitance signal is produced by a variable capacitor that is different from the variable capacitor producing any of the other variable capacitance signals. The system further has a mixer electrically coupled with the readout node, and an output electrically coupled with the mixer. The mixer is configured to substantially continuously receive the plural variable capacitance signals. In addition, the output has an output interface for delivering the plurality of variable capacitance signals in parallel. The signals at the output should represent real time signals, as compared to stale sample and hold signals used in prior art systems.
