摘要： A system and method of recording and transmitting compressed audio signals over a network is disclosed. The end node device first converts the audio signal to a spectrogram, which is commonly used by machine learning algorithms to perform speech recognition. The end node device then compresses the spectrogram prior to transmission. In certain embodiments, the compression is performed using Discrete Cosine Transforms (DCT). Furthermore, in some embodiments, the DCT is performed on the difference between two columns of the spectrogram. Further, in some embodiments, a function that replaces values below a predetermined threshold with zeroes in the Encoded Spectrogram is utilized. These functions may be performed in hardware or software.

摘要： The present disclosure describes a hydrogen sulfide decomposition process for converting hydrogen sulfide into hydrogen gas and sulfur dioxide. Such a process can significantly increase the amount of available hydrogen gas. In fact, if each Claus unit in the U.S. creating elemental sulfur in traditional systems were replaced by this hydrogen sulfide decomposition process, 1.83 million metric tons of hydrogen gas could be produced. This represents about 20% of the annual hydrogen produced in the U.S. for any purpose, recovered and available for reuse. Additionally, if desired, the sulfur dioxide can be further processed to form sulfuric acid.

摘要： A fluid distributor valve (1) for repartitioning an inlet fluid stream (Z) into two outlet fluid streams (X, Y), comprising an inlet port (10), two outlet ports (11, 12), a first and a second valve mechanism (13, 14), one arranged upstream each outlet port (11, 12), wherein each valve mechanism (13, 14) comprises a valve body (15, 16) slidable in a cylindrical valve bore (17) in reciprocating strokes through a valve shaft (18), wherein the valve body (15, 16) includes a first portion (15a, 16a) that is formed with a progressively changing diameter so as to reduce a valve gap between the valve bore inner peripheral wall and the valve body outer peripheral wall at a plane (A, B) perpendicular to the stroke direction, in a regular operating range of the valve mechanism (13, 14), from a maximum valve gap to a minimum valve gap, to reduce or increase the flow rate through the gap towards the associated outlet port (11, 12) upon the relative movement, and wherein at least one of the valve bodies (15, 16) of the valve mechanisms (13, 14), preferably both, is/are formed such that the minimum valve gap is maintained at the end position of the stroke of the valve body (15, 16) in the regular operating range.

摘要： The present invention describes a fuel-management system for minimizing particulate emissions in turbocharged direct injection gasoline engines. The system optimizes the use of port fuel injection (PFI) in combination with direct injection (DI), particularly in cold start and other transient conditions. In the present invention, the use of these control systems together with other control systems for increasing the effectiveness of port fuel injector use and for reducing particulate emissions from turbocharged direct injection engines is described. Particular attention is given to reducing particulate emissions that occur during cold start and transient conditions since a substantial fraction of the particulate emissions during a drive cycle occur at these times. Further optimization of the fuel management system for these conditions is important for reducing drive cycle emissions.

摘要： An advanced sputter target is disclosed. The advanced sputter target comprises two components, a porous carrier, and a metal material disposed within that porous carrier. The porous carrier is designed to be a high porosity, open cell structure such that molten material may flow through the carrier. The porous carrier also provides structural support for the metal material. The cell sizes of the porous carrier are dimensioned such that the capillary action and surface tension prohibits the metal material from spilling, dripping, or otherwise exiting the porous carrier. In some embodiments, the porous carrier is an open cell foam, a weave of strands or stacked meshes.

摘要： A monitoring circuit that includes a pickup loop to monitor a voltage applied to a cavity of a linear accelerator is disclosed. The monitoring circuit is electrically isolated from the linear accelerator and is also electrically isolated from the controller that receives input from the circuit and controls the linear accelerator. In certain embodiments, the monitoring circuit also includes an energy harvester so as to capture energy without any physical connection to the controller. This may be achieved using light energy or electromagnetic energy, for example. In certain embodiments, the monitoring circuit includes an analog-to-digital converter to convert the signals received from the pickup loop to digital values. In other embodiments, the monitoring circuit passes analog voltages to the controller. The outputs from the monitoring circuit may include the amplitude and phase of the voltage being applied to the respective cavity.
