  • Publication number: 20170236080
    Abstract: Techniques are provided that produce a risk profile consisting of a risk score and trends of risk scores across devices and sensors in a machine-to-machine (M2M) or Internet of things (IOT) environment. For example, a device is assigned a risk score which is based on baseline factors such as expected network packets between two devices, normal network packets, access to critical devices, authorized access requests from one device to another device, normal communications to a device, and the critical ports of a device; access to and conflicts across physical, logical, and operational systems; historical and current usage of these systems, and anomalies from normal behavior patterns. Techniques encompass risk management by computing a risk score in a timely fashion in accordance with an architecture that enables achieving the required scaling necessitated by the huge number of devices in the machine-to-machine (M2M) or Internet of things (IOT) environment.

  • Publication number: 20160082392
    Abstract: A reverse osmosis filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with the raw water ingress, permeate egress, and reject water egress. The reverse osmosis filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

  • Patent number: 9119162
    Abstract: A method and apparatus for extending the driving capacity of a power management device are provided. The method involves determining an energy requirement for the operation of a power management device. Next, the method compares the energy requirement for the operation of a power management device with a capability of a first power device. If the energy requirement is greater than the energy requirement of the first power device, the energy is switched to a second power device of higher capacity. The apparatus includes: a first power device; a second power device connected in parallel to the first power device; a first inductor connected to the first power device and a capacitor connected to the first inductor; and a second inductor connected to a second power device and a capacitor connected to the second inductor.

  • Patent number: 9095822
    Abstract: We report an electro-deionization (EDI) device having split flow arrangement for the purification of second pass RO permeate water with high flow rate in which the feed water is fed through the center port and is diverted into each section of dilute chamber with equal flow rate, producing two product streams. The EDI device has concentrate chambers adjacent to dilute chambers in two sections of the stack, allowing independent flow through the separate sections. The split flow design reduces resin bed depth requirement for processing of second pass RO permeate water. This results in higher flow rate through the stack, elimination of the pressure drop limitation, and reduction of power consumption per unit volume of water.

  • Patent number: 8901989
    Abstract: An adaptive gate drive circuit that can generate a gate bias voltage with temperature compensation for a MOSFET is disclosed. The adaptive gate drive circuit may generate the gate bias voltage with variable drive capability to combat higher gate leakage current of the MOSFET at higher temperature. In one design, an apparatus includes a control circuit and a gate drive circuit. The control circuit generates at least one control signal having a variable frequency determined based on a sensed temperature of the MOSFET. For example, a clock divider ratio may be determined based on the sensed temperature of the MOSFET, an input clock signal may be divided based on the clock divider ratio to obtain a variable clock signal, and the control signal(s) may be generated based on the variable clock signal. The gate drive circuit generates a bias voltage for the MOSFET based on the control signal(s).
