Abstract: Certain embodiments of the present disclosure are directed to methods, devices, systems, mobile devices, applications, and servers that measure or utilize measurements for quality of service of wireless communication networks by measuring a variety of real-world data transfer speeds. Certain embodiments of the present disclosure include a data-use-measuring application that can carry out data transfer rate measurements without impacting (or minimally impacting) a consumer's data usage.

Abstract: An apparatus for applying a continuous film to a tube. A carriage allows the apparatus to move axially along the exterior of the tube. A film holder retains and dispenses the continuous film. A mechanism is provided to change the orientation of the film after being dispensed from the film holder. Guide rollers spaced radially and axially about the tube shape the continuous film longitudinally about the circumference of the tube.

Abstract: A pig which may be propelled by fluid flow through a pipeline includes a cupped or hollow spherical head having an inside and an outside. The head has an opening for facing upstream and receiving fluid flow in the pipeline and has an outside for facing downstream and for contacting the inside walls of the pipeline. An elongate tail has a first end connected to the inside of the head and a second end extending out of the opening. The tail is of smaller diameter than the opening and has a length greater than about 1.5 times the largest internal diameter of the pipeline. A first fastener is provided on the outside of the head and a second fastener is provided on the second end of the tail. The fasteners are used to connect multiple pigs end-to-end and to attach objects, such as pipeline cleaning and maintenance equipment, to the pig.

Abstract: A method of making a humidity sensor comprises providing a host device constituted by a semi-conductor substrate (10) and a gate insulator (13) of an insulated gate field effect transistor, forming a layer (14) of poly (vinyl) alcohol (PVA) on the exposed surface of the insulator, heat treating the layer to crystallize and stabilize the PVA, and forming a gate electrode (15) on the PVA layer, so that the gate electrode is porous allowing ambient water vapor to be absorbed by the PVA which, in response, undergoes a change of bulk dielectric constant, thereby causing a change in gate capacitance of the transistor resulting in a detectable change of electrical conductivity in the drain source channel.

Abstract: A gas sensitive device, for example a gas sensitive MISFET (FIGS. 1 to 3) has a gas-sensitive electrode (15) comprising a catalytically active metal (e.g. Pt or Pd) and a non-metallic material (e.g. SiO.sub.2) mixed with, or deposited at an exposed surface of, the metal to modify the catalytic activity of the metal. The electrode has an enhanced sensitivity to, and selectivity of, certain gases. The composite material is applicable to other gas-sensitive devices, e.g. an optical fibre gas sensor.

Abstract: An ionic conductivity accelerometer comprises a layer of an ionically conductive material such as rubidium silver iodide (RbAg.sub.4 I.sub.5) deposited on an electrically insulative substrate with spaced electrodes in contact with the layer. The ionically conductive material may be mixed with an electrically insulative, chemically inert material such as quartz wool in order to alleviate susceptibility to cracking.

Abstract: A ground anchor has an auger fluke defined by a lower leading and upper trailing beveled cutting edges, the shape of the edges being at a non-radial or oblique angle, the disc being vertically separated in the shape of a helix and attached to an axial anchor rod. The rod is set in the ground with a socket tool that is coaxially positioned over the rod. The tool includes a helical slot engagable with the helix of the anchor fluke to rotate the anchor into the ground, to pull test the anchor, and in one embodiment capable to reverse rotate the socket tool for its removal.

Abstract: An ammonia gas sensor comprises a dual gate field effect transistor (FET) in which the two gate electrodes are of platinum deposited respectively by sputtering and evaporation. The gate regions of the two FETs are connected together differentially and the net drain source voltage represents the concentration of ammonia gas to which the sensor is exposed.

Abstract: A ground anchor includes a saddle to receive and support buried pipe and having an anchor rod that will bend from upward forces acting on the pipe yet still retaining the pipe in the ground.
