  • Patent number: 11931220
    Abstract: Wax-based compositions for making barrier layers used in oral treatment devices are thermally stable when formed into a flat sheet or three-dimensional article to a temperature of at least 45° C. and are plastically deformable at room temperature (25° C.). The wax-based compositions include a wax fraction homogeneously blended with a polymer fraction. The wax fraction includes at least one wax and the polymer fraction includes at least one polymer selected such that, when the at least one wax and at least one polymer are homogeneously blended together, they yield a wax-based composition having the desired properties of thermal stability and plastic deformability. Barrier layers and oral treatment devices made from such wax-based compositions are dimensionally stable to a temperature of at least 40° C. without external support and can be plastically deformed in a user's mouth to become at least partially customized to the size and shape of user's unique dentition.

  • Patent number: 10746138
    Abstract: An EGR cooler may include an EGR cooler housing having top, bottom and side walls, inlet and outlet end walls disposed at opposite ends, and a longitudinal axis extending in a direction of exhaust gas flow from the inlet end to the outlet end. A plurality of cooling tubes extend through the EGR cooler between the top and bottom walls, and are arranged in a cooling tube array to form an exhaust gas receiving area at an upstream side of the cooling tube array proximate the inlet end wall so that exhaust gas flowing into the EGR cooler through an exhaust gas inlet opening will flow into the exhaust gas receiving area and then disperse through the cooling tube array. A pitch distance between the cooling tubes may be greater proximate the longitudinal axis than proximate the side walls to promote flow through, instead of around, the cooling tube array.

  • Patent number: 10526986
    Abstract: According to one aspect of the present disclosure, a method of controlling an exhaust gas recirculation (EGR) system of an engine system includes determining a first EGR command according to a first method during a steady state engine condition, determining a second EGR command according to a second method during a transient engine condition, wherein the first method is based at least in part on values from a NOx sensor, and the second method is not based on values from a NOx sensor. The method further includes adjusting an EGR valve of the EGR system based on the first EGR command during the steady state engine condition, and adjusting the EGR valve based on the second EGR command during the transient engine condition.

  • Patent number: 10082114
    Abstract: An Exhaust Gas Recirculation (EGR) system for an engine system is provided. The EGR system includes an exhaust gas treatment module positioned upstream of an EGR cooler with respect to an exhaust gas flow direction. The exhaust gas treatment module is in selective fluid communication with an exhaust gas line of an engine. The EGR system also includes a bypass line in selective fluid communication with the exhaust gas line of the engine. The EGR system further includes a valve arrangement configured to route an exhaust gas flow through at least one of the exhaust gas treatment module and the bypass line.

  • Patent number: 8600938
    Abstract: A technique for updating elements in a data storage facility, including a single server or a multi-server system, such as by providing updated internal code packages to the elements. The update is performed using a fixed state machine, where the elements are updated in a coordinated manner within the constraints of the state machine. In a multi-server device, code packages are distributed to elements associated with the different servers in one traversal of the state machine, during distribute states of the state machine. The distributed code packages are activated in activate states of the state machine in multiple traversals of the state machine, so there is a serial activation. The code packages can be grouped in a flexible way by configuring an external update bundle used by the state machine. The distributing of the code is based on the grouping.

  • Patent number: 8365159
    Abstract: A method to update code in an information storage and retrieval system comprising one or more processors, and existing code, where that existing code includes a Concurrent Code Load having (N) phases, where that Concurrent Code Load invokes an as yet unwritten Temporal Coupling File. The method provides a code update image comprising that Temporal Coupling File. If the (i)th phase of the Concurrent Code Load invokes the Temporal Coupling File, then the method reads instructions for that (i)th phase of the Concurrent Code Load from the Temporal Coupling File, and executes those instructions. The method completes each phase of the Concurrent Code Load, and then operates the system using the code update.
