    摘要: The present invention relates to the field of radio frequency identification (RFID). In one form, the invention relates to a method and/or device adapted to provide at least some level of providing lateral discrimination within a given area. The invention has been developed primarily for interrogating multiple passive transponders which are attached to objects to be identified by those respective transponders and will be described hereinafter with reference to that application. A typical application is the identification of RFID transponders or other RFID devices, such as those embedded in plastic tokens or cards within a selected area and which may be provided near each other or stacked on each other.

    摘要: Where a single cable conveys bidirectional RF signals and bidirectional data using a data carrying DC power signal where the RF signals and the bidirectional data carrying DC power signal are separated using frequency selective networks. Alternatively a single cable conveys bidirectional RF signals and bidirectional data using a modulated RF data signal where the RF signals and the bidirectional modulated RF data signal are separated using frequency selective networks. A array of switchable antennas where RF switching elements are integral to the antennas is connected to the single cable and is powered by and communicated with through the cable. The array of switchable antennas can be arranged to produce an interrogation field in any of one, two or three dimensions by the antennas being arranged to provide for a series of parallel spaced conductors through which currents are sequentially switched in order to produce both tangential and normal magnetic field components. The spatial relationship of the sequentially switched currents is chosen to ensure that at different times a tangential and a normal magnetic field are produced at the same location. The conductors are preferably arranged in a planar fashion and the tangential and normal magnetic fields are produced above the planar surface. A single layer of parallel spaced conductors provides for one or two dimensional operations. Adding a second parallel layer of orthogonally oriented parallel spaced conductors provides three dimensional operations where currents are sequentially switched in both layers.

    摘要: A frame over which woven wire mesh is to be stretched and secured to form a sieving screen and which can be used to screen solids from drilling mud recovered from down-hole when drilling for oil or gas. The frame is a rectilinear moulded plastics frame having edge regions by which it is secured in place in a shaker. Within the frame is a plurality of rectilinear windows formed by an orthogonal array of intersecting ribs also of moulded plastics material. Some of the ribs are internally reinforced by rigid metal members which extend orthogonally between hollow box-section members which define a sub-frame for reinforcing the four edge regions of the frame. The orthogonal members are secured at their ends to the sub-frame. The ends of the sub-frame members are joined at the four corners of the sub-frame. In this way not are only the edge regions of the frame reinforced internally but so also are some of the orthogonally intersecting ribs, so as thereby to produce a rigid frame for the screen. The internal reinforcement for those ribs which are to be reinforced may comprise hollow box-section metal members which may be of similar cross section to that of the sub-frame members, or the internal reinforcement for those ribs which are to be reinforced comprises metal I-beam cross section members, which typically have the same height as the height of the box-section members forming the sub frame.

    摘要: A frame over which woven wire mesh is to be stretched and secured to form a sieving screen and which can be used to screen solids from drilling mud recovered from down-hole when drilling for oil or gas. The frame comprises a rectilinear moulded plastics frame having edge regions by which it is secured in place in a shaker. Within the frame is a plurality of rectilinear windows formed by an orthogonal array of intersecting ribs also of moulded plastics material. Some of the ribs are internally reinforced by a structure comprising two spaced apart layers of orthogonal intersecting spaced apart wires, running parallel to the length and breadth of the rectilinear shape of the frame within the ribs to increase their rigidity. The edge regions of the frame are reinforced internally by metal box-section members joined at their four corners and defining perimeter reinforcement, and the ends of the wires are secured to the box-section members. The latter are encapsulated in the same plastics material from which the orthogonal array of intersecting ribs are moulded. Alternate ribs are not reinforced with wires, and the non-reinforced ribs only extend partway between the upper and lower faces of the frame. Lengths of wire bent to form spacers and adapted to fit between upper and lower wires of the rib reinforcing structure, are joined to the upper and lower wires so as to extend therebetween and maintain the desired separation of the two layers of wires during the plastics encapsulation/moulding process.

    摘要: A pneumatic tire for dirt track racing comprising lateral and circumferential grooves forming blocks on the tread surface. The blocks have leading and trailing edge walls. The trailing edge walls of the blocks are buttressed by inclining the walls at an angle of 20°-60° relative to a line perpendicular to a tangent to the tread, and the edge wall extends into the groove by a distance of approximately one-half the tread width. The leading edge walls of the blocks have a radially outer portion inclined at about zero degrees and a radially inner portion have a radius of curvature of infinity or less, wherein the intersection point between the two portions is at about one-half the groove depth.
