  • Patent number: 10488994
    Abstract: A capacitive sensor is provided that includes an array of sensor electrodes deposed in single layer on a substrate. The array includes a number of columns of sensor electrode sets arranged in a row. Each column of the sensor electrode sets includes a plurality of transmitter electrode elements and at least one receiver electrode. The transmitter electrode elements are deposed in a staggered arrangement in a direction of the column, wherein each transmitter electrode element has a trace led out from a first end thereof along the direction of column. The at least one receiver electrode is deposed along the direction of column and is interdigitated with the transmitter electrode elements for capacitively coupling with the transmitter electrode elements. At least part of the transmitter electrode elements has an extension extending from a second end of the transmitter electrode element along a direction opposite the direction of the trace.

  • Patent number: 9113544
    Abstract: A method for producing hyperthermal molecular hydrogen is disclosed and use of same for selectively breaking C—H or Si—H bonds without breaking other bonds are disclosed. A hydrogen plasma is maintained and protons are extracted with an electric field to accelerate them to an appropriate kinetic energy. The protons enter into a drift zone to collide with molecular hydrogen in gas phase. The cascades of collisions produce a high flux of hyperthermal molecular hydrogen with a flux many times larger than the flux of protons extracted from the hydrogen plasma. The nominal flux ratio of hyperthermal molecular hydrogen to proton is controlled by the hydrogen pressure in the drift zone, and by the length of the drift zone. The extraction energy of the protons is shared by these hyperthermal molecules so that average energy of the hyperthermal molecular hydrogen is controlled by extraction energy of the protons and the nominal flux ratio.

  • Publication number: 20020194083
    Abstract: In a computer network, services are provisioned for a user over the network, typically via a series of messages. Depending on the particular service to be provisioned many network entities may be concerned with the provision of a particular service. However, an initiator of a service request may be unaware of all the network entities concerned with a service provision request. A system which receives a single request for service provisioning from an initiator, determines each network entity corresponding to the request from a common repository of network entities, and applies the operations concerned with the service provision request at each corresponding network entity, allows a service to be provisioned without manually searching and examining the network to determine the network entities concerned with a particular service provision request.

  • Patent number: 6453870
    Abstract: An electrically conducting fuel filter mechanism for a fuel supply system for an internal combustion engine. The housing for the fuel filter has a conductive inner or core layer and at least one non-conductive outer layer positioned adjacent the fuel. The conductive layer is made from a non-conductive material with conductive fibers or powders mixed in it, while the non-conductive layer is free from the conductive materials. Any electrostatic or electrical charge buildup in the fuel filter, fuel or housing, will be dissipated through the inner non-conductive layer forming conductive paths directly to the conductive layer. This prevents any further charge buildup and pitting.
