Abstract: The invention captures harvestable mechanical energy, e.g., in the form of wind or moving water, and uses it for electrical generation or other work. In various embodiments a turbine is used to pressurize a fluid, and the pressurized fluid is then optionally stored and then used to drive an electric generator. Because the pressurized fluid can be stored in a pressurized state indefinitely, the invention provides a straightforward way to accumulate the mechanical energy until it is needed. Additionally, the invention allows portions of the system, e.g., a pressure vessel or generator, to be located away from the turbine, reducing the costs of deploying and maintaining the system.

Abstract: The invention generally relates to systems and methods for increasing effective spectrum. The invention provides wireless antennas that transmit or receive within a narrow spectrum at distances that overlap the reach of neighboring antennas and that also transmit or receive within a broader spectrum at restricted distances that do not interfere with the operation of neighboring antennas. This way, within a network of antennas, each antenna can use the full band of spectrum for wireless communications.

Abstract: The invention generally relates to rapid reading of data from multi-level cell (MLC) memory devices. Information is stored in a way that allows all of the bit-space to be used but that also allows single-read-per-cell retrieval. Data is triaged into high priority data and low priority data. The high priority data is then stored in an MLC memory device with one bit per cell. This data can them be read from the MLC cells by one comparison operation on each cell, accomplishing all of the required read operations in parallel in the time it takes to perform a single comparison. Low priority data is stored in the remaining bit-space of the cells, to take full advantage of all of the available bit-space of the cells.
