  • Publication number: 20190068217
    Abstract: Various embodiments of the invention provide systems, devices, and methods for decompressing encoded electronic data to increase decompression throughput using any number of decoding engines. In certain embodiments, this is accomplished by identifying and processing a next record in a pipeline operation before having to complete the decompression of a current record. Various embodiments take advantage of the knowledge of the method of how the records have been encoded, e.g., in a single long record, to greatly reduce delay time, compared with existing designs, when decompressing encoded electronic data.

  • Publication number: 20190030867
    Abstract: Treatments are provided to strengthen adhesion of an optical filter layer in a photovoltaic (PV) module to an encapsulant layer, or generally, between inorganic materials and organic polymers. The embodiments disclosed herein can provide five or more times the adhesive forces of untreated encapsulant-filter interfaces. As a result, the system can enhance long-term reliability of PV modules by reducing interface surface charges and dangling bonds and reducing gaps and cracks, thereby preventing moisture, impurities, and particles from entering the interface. The treated optical filter layer can result in a surface modification. In some embodiments, treating the optical filter layer includes applying a chemical treatment such as an acid or alkaline wash, and/or ultrasonic cleaning.

  • Publication number: 20190006723
    Abstract: Embodiments of the present invention include a battery management system that provide a plurality of channels that allow communication between host and clients. This communication may operate in bi-directional modes such that commands from the host and responses from the clients are transmitted clockwise or counter-clockwise around a daisy-chain loop. This architecture provides both a high level of redundancy across multiple channels as well as transmission directions around the loop. The use of multiple channels provides a separation in signal paths akin to the provision of completely separate physical wires, preventing malfunction of spurious operation of devices using one channel from interfering with the normal operation of devices using the other channel. In addition, the signaling architecture allows a host to dynamically transmit commands and receive responses between specific client(s) and host or broadcast communication across all clients.

  • Publication number: 20180342640
    Abstract: A colored photovoltaic (PV) module or roof tile including a layer of highly stable nanoparticles provides uniform, angle-independent viewer color. The nanoparticles can comprise a metal oxide such as zinc oxide, titanium dioxide, or iron oxide. The nanoparticles can have composition and/or size tuned to absorb wavelengths of light reflected from PV cells, effectively concealing their appearance, and tuned to scatter wavelengths in a desired color range. The disclosed embodiments can provide better color uniformity and better efficiency, and be more cost-effective, than existing approaches for manufacturing colored PV modules. During the manufacturing process, a coating system, which may include one or more nozzles, can spray an inside surface of a glass cover with nanoparticles, which can be suspended in a solvent (such as water or isopropyl alcohol). The nanoparticle layer can then be encapsulated directly inside an encapsulant layer.

    Abstract: A vehicle seat restraint system includes a control system and a second-row restraint system. The control system receives a first-row seat value and a second-row seat value from seat sensors. The control system generates relative position data for a first-row seat and a second-row seat based upon the first-row seat value and the second-row seat value. The control system selects a load limiter setting value using a multidimensional load limiter model based upon body impact values as a function of load limiter setting values and the relative position data, a selected load limiter setting value outside a value avoidance zone for the body impact values. The second-row restraint system is configured by the control system with the selected load limiter setting value. The control system may also determine an occupant weight value and select the load limiter setting value using the occupant weight value.

    Abstract: An electric motor includes a case, a stator having stator windings, a rotor having a rotor shaft, and at least one main rotor bearing coupling the rotor shaft to the case. Common mode charge builds up on the rotor due to imbalances of the stator. The at least one main rotor bearing has a first electrical resistance between the rotor shaft and the case. The electric motor further includes a rotor discharge bearing coupling the rotor shaft to the case. The rotor discharge bearing has a second electrical resistance between the rotor shaft and the case that is less than the first electrical resistance, causing the common mode charge to discharge through the rotor discharge bearing. In a differing embodiment, a rotor discharge brush coupled between the case and the rotor shaft along the longitudinal axis of the rotor shaft discharges the common mode charge.
