  • Publication number: 20180277993
    Abstract: A sliding contact assembly for a DC electrical outlet receives plug contacts of an electrical plug. The assembly includes sliding contact structure having a base and a plurality of electrical sliding contacts fixed to the base. A housing includes a first end wall having an internal top surface and second end wall opposing the first end wall. The second end wall has an internal bottom surface. The housing has a side wall structure defining an internal chamber between the top surface and the bottom surface. The sliding contact structure is disposed in the housing to be movable linearly within the chamber. A spring is disposed between the top surface of the housing and a surface of the base so that when the plug contacts are completely disconnected from the associated sliding contacts, the spring rapidly forces the sliding contacts away from the plug contacts, reducing arcing energy there-between.

  • Publication number: 20180259678
    Abstract: Post-processing corrections can be applied to operational numerical model forecasts of weather variables to reduce forecast model errors. The post-processing technique is based on an analog post-processing correction scheme. In the analog scheme, the system searches for previous model forecasts that are similar to the current forecast, and modifies the current forecast based on errors in such previous predictions. An “abnormal (or abnormal) index” can be generated for each analog as a function of several meteorology variables (i.e., humidity, pressure and temperature) and two experience coefficients. The abnormal index can be used to exclude some errors. Furthermore, dynamic weights based on the “abnormal index” can be applied to the errors. Using the “abnormal index” weights in a post-processing technique may generate a more accurate air quality forecast.

  • Publication number: 20180260614
    Abstract: A first face region within a first image is determined. The first face region includes a location of a face within the first image. Based on the determined first face region within the first image, a predicted face region within a second image is determined. A first region of similarity within the predicted face region is determined. The first region of similarity has at least a predetermined degree of similarity to the first face region within the first image. Whether a second face region is present within the second image is determined. The location of the face within the second image is determined based on the first region of similarity, the determination of whether the second face region is present within the second image, and a face region selection rule.

  • Publication number: 20180210469
    Abstract: A system, method and computer program product for establishing and using a pollutant emission scavenging forecasting (PESF) model to calculate a purgeable pollutant emission to dynamically control an emitted pollutant at any target concentration. The dynamic control considers the initial pollutant concentration and pollutant scavenging ability of atmosphere. The method further takes into account the constraint conditions specified by a user, and employs a dynamic emission correction system to quickly calculate an optimal pollutant emission scheme. If the emission is lower than minimum acceptable value for a current time instance (a moment), the method corrects the emission intensity before (prior to) this moment by changing the initial concentration at this time. This initial concentration is the final pollutant concentration of a prior moment.

If the emission is lower than minimum acceptable value for a current time instance (a moment), the method corrects the emission intensity before (prior to) this moment by changing the initial concentration at this time. This initial concentration is the final pollutant concentration of a prior moment. Since the method makes full use of the atmospheric pollutants scavenging ability, the dynamic emission control scheme can provide the most effective and lowest economic losses solution.

  • Publication number: 20180188952
    Abstract: Provided are an apparatus, system and method for apparatus, system and method for throttling an acceptance rate for adding host Input/Output (I/O) commands to a buffer in a non-volatile memory storage device. Information is maintained on an input rate at which I/O commands are being added to the buffer and information is maintained on an output rate at which I/O commands are processed from the buffer to apply to execute against the non-volatile memory. A determination is made of a current level of available space in the buffer and an acceptance rate at which I/O commands are added to the buffer from the host system to process based on the input rate, the output rate, the current level of available space, and an available space threshold for the buffer to maintain the buffer at the available space threshold. I/O commands are added to the buffer to process based on the acceptance rate. The I/O commands are accessed from the buffer to process to execute against the non-volatile memory.

  • Patent number: 9998117
    Abstract: A resettable solid state fuse that automatically restores an interrupted circuit after an overcurrent event is cleared. The resettable solid state fuse can include one or more switching devices, such as, for example, a normally-on power semiconductor, and one or more positive temperature coefficient (PTC) resistive elements. The switching device is structured to extend the voltage rating of the resettable fuse, allowing the solid state resettable fuse to attain both a relatively elevated voltage rating and a relatively elevated electrical current rating while using a PTC resistive element. According to certain embodiments, the solid state resettable fuse can be tripped by a cascaded PTC resistive element, thereby providing a passive electronic device that can operate in the absence of electronic sensing, detection, and tripping, as well as without reliance on an auxiliary power supply.

  • Patent number: 9666977
    Abstract: Technologies for providing DC arc protection in a DC socket include an electromagnet positioned in the DC socket configured to produce a magnetic field. The electromagnet is positioned to be adjacent to a contact region between one or more supply terminals of a DC socket and one or more prongs of a DC plug. As the DC plug is disconnected from the DC socket, a DC arc might form between one or more of the supply terminals and one or more of the prongs. The magnetic field produced by the electromagnet reduces the energy of the DC arc and reduces the time duration of the DC arc.
