  • Sparse matrix storage in a database
    Patent number: 10275479
    Abstract: Methods, processes and computer-program products are disclosed for use in a parallelized computing system in which representations of large sparse matrices are efficiently encoded and communicated between grid-computing devices. A sparse matrix can be encoded and stored as a collection of character strings wherein each character string is a Base64 encoded string representing the non-zero elements of a single row of the sparse matrix. On a per-row basis, non-zero elements can be identified by column indices and error correction metadata can be included. The resultant row data can be converted to IEEE 754 8-byte representations and then encoded into Base64 characters for storage as strings. These character strings of even very large-dimensional sparse matrices can be efficiently stored in databases or communicated to grid-computing devices.

  • Radio access network service-assisted, sensor based indoor navigation
    Patent number: 9977133
    Abstract: Examples are provided that enable a cellular network location assist to confirm a position determined using a sensor of a mobile device. As a result of global positioning system signals becoming unavailable due to the mobile device traveling indoors, the mobile device implements a sensor-based position determination that provides a position of the mobile device as the mobile device travels about a location. In order to confirm the reliability of the sensor-based position determination, the mobile device, after passage of time or after traveling some estimated distance, requests location assistance indications from the cellular network. A processor of the mobile device receives the location assistance indications and generates a directional vector based on several of the location assistance indications. Using the directional vector, the processor confirms the reliability of the dead reckoning position.

  • CONTROLLED ENERGY STORAGE BALANCE TECHNOLOGY
    Publication number: 20180069403
    Abstract: An energy storage system that comprises an energy reservoir and a system controller. The energy reservoir is charged by DC energy from a DC energy source while discharging DC energy to a DC/AC converter. A system controller regulates the DC energy discharged from the energy reservoir to the DC/AC converter to nearly balance the amount of DC energy charged into the energy reservoir. Because this charging and discharging is nearly balanced, the size of the energy reservoir can be made quite small relative to the amount of charging and discharging. This is advantageous where the flow of charge and discharge is high, as might be the case if the energy reservoir receives charge from all or a substantial portion of a power station, such as a solar power station. With such a controller, the use of an energy reservoir becomes technically feasible even with such large current flows.
