Patent number: 7405656Abstract: This invention involves encapsulating an RFID device in an encapsulating material by known encapsulating processes to form a domed, encapsulated RFID tag. The encapsulating material may be translucent or opaque, flexible or hard, and has minimal effect on transmission or reception of radio frequency (RF) signals. The invention further involves a stand-off bracket, composed of one or more materials that have minimal effect on transmission or reception of RF signals, for mounting an RFID device on or near materials that impede RF transmission and reception. The encapsulated RFID tag and stand-off bracket, separately, may have an adhesive or other attachment means on one of their surfaces so that they may be adhered or otherwise attached to another surface. In one application, an encapsulated RFID tag in the 860-928 MHz range is mounted on a stand-off bracket and may be used for tracking items to which it is attached.Type: GrantFiled: October 25, 2004Date of Patent: July 29, 2008Assignee: United Parcel Service of America, Inc.Inventor: John Olsen

Publication number: 20080116609Abstract: A method for making a reinforced composite separator plate is disclosed. According to the method, a reinforcement media (16) is molded into a composite material (22, 24) such as graphite embedded in a thermoplastic or thermosetting polymer resin matrix. The composite material is placed in a mold cavity (15, 17) such that the composite material flows through the reinforcement media. The separator plate is molded into a net step. The molding is performed via injection or compression moulding, or a combination of both.Type: ApplicationFiled: January 10, 2006Publication date: May 22, 2008Inventor: Joseph B. Darke

Patent number: 7373719Abstract: A method of manufacturing a terminal block for a telecommunication cable comprising the steps of providing a mold having a first half and a second half, each forming a respective body cavity configured to form a terminal block and configured to receive a substrate comprising a plurality of openings adapted to receive an insulated electrical contact. A plurality of projections extend from the first half into the cavity, wherein the plurality of projections are adapted to remove a portion of insulation from the electrical contact positioned within each of the openings. The substrate is positioned in the mold and the insulated electrical contact is inserted into each of the openings. The mold is closed such that the plurality of projections remove a portion of the insulation from the insulated electrical contact upon closing of the mold. A dielectric material is then injected into the mold containing the substrate and insulated electrical contact to form a terminal block.Type: GrantFiled: November 9, 2004Date of Patent: May 20, 2008Assignee: Channell Commercial CorporationInventors: William H.
