Abstract: Methods of fabricating transistor in which a first Group III nitride layer is formed on a substrate in a reactor, and a second Group III nitride layer is formed on the first Group III nitride layer. An insulating layer such as, for example, a silicon nitride layer is formed on the second Group III nitride layer in-situ in the reactor. The substrate including the first Group III nitride layer, the second group III nitride layer and the silicon nitride layer is removed from the reactor, and the silicon nitride layer is patterned to form a first contact hole that exposes a first contact region of the second Group III nitride layer. A metal contact is formed on the first contact region of the second Group III nitride layer.

Abstract: Methods, systems and computer program products of dynamic communication data routing by a multi-network remote communication terminal across a plurality of networks are provided. The multi-network remote communication terminal is delivered to a locality to receive communication services. The terminal is communicatively connected to a first network, a second network, the second network having a communication characteristic different from the first network, and to a user endpoint device positioned in the locality. Communication data directed to a target device from the user endpoint device is received at the terminal. A characteristic of the received communication data is determined. Routing of received communication data to the target device is allocated across the first network and/or the second network based on the determined characteristic of the received communication data and the communication characteristics of the first and second network.

Abstract: A fluid displacement apparatus includes a housing defining a chamber therein having a first port and a second port. First and second helical rotors with opposing pitches are meshed within the chamber, in fluid communication with the first and second ports. A respective one of the first and second helical rotors includes a cylindrical body portion having a helical groove therein and a helical tooth portion extending radially from the cylindrical body portion adjacent the helical groove. The first and second helical rotors are arranged such that respective longitudinal axes of the first and second helical rotors are parallel to one another and a helical tooth portion of one of the first and second helical rotors engages a helical groove of another of the first and second helical rotors, such that the first and second helical rotors are operative to rotate within the chamber and provide fluid transport between the first and second ports parallel to the longitudinal axes.
