Abstract: A method and system for an application to load one or more files from a device (e.g., local disc of the device) rather than from a location outside of the device (e.g., a server) via a service worker. The service worker can communicate with one or more main JavaScript threads (e.g., clients) via one or more corresponding service worker bridges that communicates with one or more corresponding main JavaScript thread bridges that communication with the main JavaScript threads. The main JavaScript threads can communicate with the local disc of the device (e.g., native) to retrieve the one or more files and transmit them to the service worker such that the service worker can provide the one or more files to the application. In this manner, service workers can provide service with data stored in a memory of a computer device of a computer.

Abstract: A dual antenna transmitter includes a diversity encoding module that receives a data stream and provides a pair of encoded data streams selected to cause generation of overlapping symbols that provide substantially constant signal power to a receiver when the first and second antennas are unobstructed from the receiver. The diversity encoding module may compensate for the state retention of standard modulators thereby enabling the implementation of the Alamouti transmit diversity scheme. A wireless receiver capable of receiving data transmitted from the aforementioned transmitter includes a metric extraction module that repetitively extracts a metric from a transmitted signal at a selected rate to provide a first and a second metric stream, the first metric stream comprising data that is time offset from data in the second metric stream, the time offset corresponding to a differential time delay to the receiver for symbols emitted from the transmitter antennas.

Abstract: A ring impeller includes a central hub with a first row of vanes extending from the hub and a second row of vanes extending from the hub adjacent to and staggered from the first row of vanes. The vanes in each row are grouped to form adjacent vane pairs and a partition wall is positioned between each of the vanes within the vane pairs. A rib extends radially from the hub in alignment with the partition wall and is positioned between each vane pair. The bottom thickness of the partition wall is the same thickness as the rib. The partition wall includes a reduced material area at its forward and rear edges. The vanes in the first row are unevenly spaced and the vanes in the second row are spaced equidistantly between the vanes in the first row. The spacing of the vanes in the first row may be about 70% to about 140% of a spacing equal to an equal spacing. Some of the vanes may have a height that is less than the height of other vanes.

Abstract: A fuel sender assembly comprises an electric fuel pump held in a mounting plate which is, in turn, mounted in a fuel tank, such as an automotive fuel tank. The mounting plate includes a chamber wall that defines a pump chamber having an inboard end and an outboard end. The electric fuel pump is received in the pump chamber such that an inlet end, which includes a fuel inlet, is disposed within the fuel tank adjacent the inboard end of the pump chamber. The outlet end of the fuel pump includes the electrical terminals and is disposed adjacent the outboard end of the pump chamber so that the electrical terminals are accessible outside the fuel pump for connection to an external power source. A hermetic seal is formed between the fuel pump and the chamber wall to prevent vapors from escaping through the pump chamber. The fuel sender assembly permits electrical connections to be made to the fuel pump without requiring wires within the fuel tank.
