Abstract: A battery charger compatible with AC/DC power sources is provided. The battery charger comprises a power output port connected to a battery, a rectifier electrically connected between an AC connecting port and the power output port, and a power conversion unit electrically connected between a DC connecting port and the power output port. When the AC connecting port receives an AC power, the rectifier rectifies the AC power into a DC power and outputs the DC power to the power output port. When the DC connecting port receives an DC input power and the AC power is not received by the AC connecting port, the power conversion unit transforms the DC input power into the DC power and outputs the DC power to the power output port. The battery charger is a 2-in-1 charger that can charge the battery using either the DC power or the AC power.

Abstract: A hose includes an inner layer containing a fluoroelastomer, an outer layer containing one or more EPDM elastomer and EPM elastomer, and at least one textile reinforcement layer disposed between the inner layer and the outer layer. In some aspects, the at least one textile reinforcement layer is wound directly onto inner layer. Further, the textile reinforcement layer(s) may be an open braid textile which facilitates direct contact between the outer layer and the inner layer. In some cases, the fluoroelastomer has a fluorine content which is within the range of 64 weight percent to 71 weight percent. The fluoroelastomer may have repeat units which include at least two perflurorinated monomers and at least one cure site monomer, while in other cases, the fluoroelastomer has repeat units which include a perfluoroolefin monomer, a perfluorovinyl ether monomer, and a cure site monomer.

Abstract: Provided herein is a method, including a) transferring an initial pattern of an initial template to a substrate; b) performing block copolymer self-assembly over the substrate with a density multiplication factor k; c) creating a subsequent pattern in a subsequent template with the density multiplication factor k; and d) repeating steps a)-c) with the subsequent template as the initial template until a design specification for the subsequent pattern with respect to pattern density and pattern resolution is met.

Abstract: Ultrasonic transmitters that can be used for ranging in mobile devices are disclosed. In some examples, an ultrasonic transmitter device can be configured to transmit ultrasonic signals in multiple frequency bands. The transmitter can include multiple sets of ultrasonic transmitters, each capable of transmitting in a different frequency band. In other examples, frequency-adjustable ultrasonic transmitters can be used. The transmitters can be configured to change one or more of a length, mass, or tension of a membrane to change a resonant frequency of the membrane. In some examples, the transmitter can include a non-uniformly shaped membrane capable of vibrating at more than one resonant frequency. The ultrasonic transmitters can be included within a housing configured to control the flow of air within and out of the housing. The transmitter membrane can further be formed on a patterned substrate configured to increase the sound pressure levels produced by the transmitter.

Abstract: The present invention provides a method for predicting prognosis of hepatocellular carcinoma patients based on measurement of the relative level of expression of a combination of 15 immune genes of interest, or a subset thereof, in the tumors of such patients. Tumor material can come from surgical resection or biopsy. The relative gene expression information may be combined in an algorithm. The signature can be used by itself or in combination with other information such as stage information.

Abstract: There is disclosed a recovery node testing system and method. The system and method include copying a protected server image associated with a protected server to a test node and creating a test environment for the test node, the test environment including at least one of the network characteristics of the protected server. The test node may then be activated using the protected server image which may then be connected to the virtual network. Once connected, at least one test is performed on the test node to confirm that the protected server image operating on the test node responds in the same manner as the protected server.
