Abstract: A mobile computing device is presented. The mobile computing device has two housing segments that each contains a set of electrical components. The housing segments are slideably coupled to each other to move between a first position and a second position. The mobile computing device also has a cable connector that connects the sets of electrical components together. The cable connector is configured to include three connector structures that are each configured to mate with a connector. A first connector structure is configured to mate with a first connector of the first housing segment in connecting to the first set of electrical components. Similarly, a second connector structure is configured to mate with a first connector of the second housing segment in connecting to a first portion of the second set of electrical components.

Abstract: A display assembly may include a plurality of pixel elements, of which a set of pixel elements include both a display cell and a memory cell. The display cell and the memory cell may be connected to receive data from a common source at the same time.

Abstract: A system and method optimizing data throughput to a processor from a storage device having sequential data access capabilities where the processor enables its data cache for memory operations involving the storage device. The system includes a processor coupled to the data storage device, e.g., a NAND flash memory. The processor establishes an address window used as a cache (CW) for reading data from the flash memory and also establishes a non-cacheable address window (NCW) for commands, address delivery and writes to the flash memory. The CW is sized to be larger than the processor data cache to ensure that reads from the flash memory always encounter a cache-miss so that read data is obtained directly from the flash memory. By reading through the CW from the flash memory, the processor takes advantage of bursting, pipelining and data prefetch efficiencies which significantly increase data throughput.

Abstract: A video controller providing control signals for one or more screen resolutions. The video controller does not change or modify the pixel data for a video signal with a screen resolution. Accordingly, the video controller does not require additional computing or memory resources. Furthermore, because the video controller can be implemented by counters and logic gates, the video controller does not require additional hardware resources. The video controller also provides a convenient architecture for scrolling images with a higher screen resolution in a viewing device that only supports a lower screen resolution.

Abstract: A braille cell assembly is described which provides precision cell positioning. Such assembly includes a holder in the form of a tray which engages the individual braille cells, which holder is selected to be capable of itself rigidly maintaining the individual cells in predetermined positions adjacent to one another. The position of each cell in the assembly is thus independent of other cells of the assembly.
