Abstract:
A system includes a controller configured to estimate a brake specific nitrogen oxide emission of an engine based on a plurality of sensed parameters of the engine. The controller is also configured to control one or more control variables of the engine to reduce specific fuel consumption while ensuring compliance of brake specific nitrogen oxide emissions within predetermined limits.
Abstract:
A control system includes an estimator configured to determine a present state of a device and compare the present state of the device with an expected state of the device. The control system further includes a predictor operatively coupled to the estimator, and configured to predict an event for execution by the device to reach the expected state of the device. The control system also includes a supervisory control unit operatively coupled to the predictor and the device, and configured to facilitate execution of the predicted event by the device.
Abstract:
A system and method increase yield from semiconductor wafer electroplating. The aspects include a semiconductor wafer, the semiconductor wafer comprising a plurality of die areas. A plating ring for holding the semiconductor wafer in position during electroplating is also included, the plating ring substantially surrounding a circumference of the semiconductor wafer and having a width that varies in order to avoid overlap near edge die areas of the semiconductor wafer.
Abstract:
A method and system for manufacturing an integrated concentrator photovoltaic device is disclosed. In an embodiment, the invention includes a one step process using a sheet of coupling material provided in a pre-arranged pattern to couple an array of photovoltaic members to an array of respective optical concentrating members. In another embodiment, the invention includes an integrated concentrator photovoltaic device made by coupling a photovoltaic member and an optical concentrating member together through an encapsulant or coupling layer formed from a sheet member of coupling materials possessing a pre-arranged pattern
Abstract:
A fuse formed in an integrated circuit die includes: a length of an electrically conductive material for connecting two points of a circuit on the integrated circuit die and for selectively breaking the connection by a pulse of electrical current sufficient to dissolve a portion of the electrically conductive material; a passivation layer formed over the length of electrically conductive material; and a protective coating formed over a portion of the length of electrically conductive material in addition to the passivation layer to avoid damage to the fuse from an etchant during a bumping process.
Abstract:
A method of casting a refractory article. The method includes providing a mold formed from a slurry composition comprising plaster and fibers and adding a refractory composition to the mold. The method also includes allowing the refractory composition to set. The refractory composition comprises colloidal silica.
Abstract:
Various embodiments for managing uplink transmissions in a mobile communication device may include receiving, on a first subscription of the mobile communication device, an uplink grant from a first network and determining whether a tune-away from the first subscription to a second subscription of the mobile communication device is scheduled to occur during reception of a response message sent from the first network following an initial transmission of a data packet according to the uplink grant. The mobile communication device may use a block error rate and a buffer status report index of a connection between the first subscription and the first network to determine how to manage uplink transmissions following the tune-away.
