Abstract: An RFID tag and an RFID access card configured to reduce detuning effects from a typical RFID environment. The present invention provides an RFID tag that is specifically configured to reduce the detuning effects caused by initiating communication between an RFID tag and an RFID tag reader in the presence of materials such as metal, liquid, and the human body. In one embodiment, the present invention provides an RFID tag comprising an electronic circuit portion attached to a main antenna body portion, the main antenna body portion having two opposite side portions, which are substantially symmetrical with respect to one another, wherein each side portion extends outwardly to form a generally side-oriented v-shape.

Abstract: A hose coupling for connecting lengths of fire hose is formed by coupling halves. Each coupling half includes a hose connection piece and a cam ring rotatable relative to the hose connection piece. The cam rings provide a bayonet-type locking engagement. The hose connection piece has two serially arranged axially extending sections each of different diameters. The larger diameter section receives and holds a length of the fire hose. A neck on the cam ring is rotatably attached to the smaller diameter section. The neck on the cam ring is held on the smaller diameter section against movement in the axial direction. A resilient back-springing holding ring is located adjacent the free end of a smaller diameter section in a recess in the section. The holding ring in combination with the free end of the smaller diameter section forms an annular space in which a sealing ring for the coupling is secured.

Abstract: A misalignment connector has a pair of hubs providing internal, opposed spherical surfaces loaded into engagement with an internal, metal sealing ring having a spherical, outer sealing surface, the hubs being constrained together to maintain loading of the seal ring over a range of angles of misalignment. The internal seal ring is initially retained in position with respect to one of the hubs and is shiftable for proper sealing and loading engagement by the hubs over the range of permissible misalignment. The metal-to-metal seal between the hubs and the seal ring is backed up by a resilient seal. The metal seal ring has an outer peripheral projection forming a connection for the retainer, and the projection is engageable by the hubs to angularly shift the seal ring during assembly.
