Abstract: The present disclosure includes methods and systems for creating, using, and controlling LED headlight topologies and matrices that require fewer parts, electricity, and power, while allowing for advanced features such as bend lighting. The disclosed methods and systems can enable the use of smaller electrical systems, including control systems for LED and other headlight topologies. The disclosed methods and systems can also take advantage of pixel pairing and time multiplexing, among other methods, to manage electrical flow to minimize power needed over the circuit at given times, thus reducing the amount of material needed to create the LED headlight topology and related methods and systems for creating, using, and controlling the LED headlight topology.

Abstract: A remote microphone device for a hearing aid system comprises a multitude of microphones providing a corresponding multitude of electric input signals; a digital signal processor for providing a processed signal in dependence of said multitude of electric input signals. The processor comprises a noise reduction system comprising at least one beamformer for providing a spatially filtered signal. The remote microphone device further comprises a wireless communication interface comprising antenna and transceiver circuitry allowing the remote microphone device to transmit said processed signal comprising said spatially filtered signal or a further processed version thereof to said hearing aid system; a rechargeable battery; a casing having a planar structure with a form and size as a standard credit card; and a user interface configured to allow the user to control functionality of the remote microphone device. The invention may e.g. be used in hearing aid systems or headsets.

Abstract: A perforating gun system with at least one gun. Each of the perforating guns have charges disposed in a gun carrier that are angled to the longitudinal axis of the gun to achieve a predetermined proppant transport profile into clusters within a stage in a well casing. The perforation tunnels may also have burrs on each side of the casing and acts in initially aiding proppant transport during fracture treatment. A method of tuning a cluster to achieve a desired fracturing treatment based on a feedback from another cluster includes selecting a hole diameter, a hole angle for creating an angled opening, a discharge coefficient, and a proppant efficiency. Moreover, a method of improving perforation charge efficiency.
