Patent number: 6848616Abstract: A system having an RFID transceiver is adapted to communicate exclusively with a single RFID transponder located in a predetermined confined transponder target area. The system includes a magnetic coupling device comprising a magnetic flux generator responsive to a radio frequency input signal and a magnetic field pattern former. The pattern former is configured to collect flux produced by the flux generator and to form a field pattern in the location of the transponder target area. The system establishes, at predetermined transceiver power levels, a mutual magnetic coupling which is selective exclusively for a single transponder located in the transponder target area.Type: GrantFiled: March 11, 2003Date of Patent: February 1, 2005Assignee: ZIH Corp., a Delaware Corporation with its principal office in Hamilton, BermudaInventors: Boris Y.

Patent number: 6848941Abstract: A cable-connector system advantageously used with flexible, relatively small diameter coaxial cable and connectors, including a coaxial cable with a foam dielectric surrounding an inner conductor; and a tubular outer conductor surrounding the foam dielectric, the outer conductor being composed of aluminum or aluminum alloy and having helical corrugations; and a connector, having: a connector body having a hollow bore with internal perturbations keyed to the helical corrugations and arranged to retentively receive and secure the connector on the cable when the connector is screwed onto the cable with the corrugations engaging the perturbations; the connector body having a crimp section adapted to be compressed by a connector crimping tool; the crimp section configured such that when crimped, the crimp section deforms inwardly and distorts the cable outer conductor corrugations to prevent relative rotation between the cable and the connector body and interlock the connector and cable.Type: GrantFiled: March 17, 2003Date of Patent: February 1, 2005Assignee: Andrew CorporationInventors: James Wlos, James Krabec

Patent number: 6840803Abstract: A corrugated coaxial cable connector, field installable with a hand crimp tool has a connector interface coupled to the connector end of a hollow cylindrical body; an inner surface of the body is adapted to thread onto the helical corrugations on the outer conductor of the cable. A plurality of ridges on an outer surface of the body corresponding to an internal threaded section forms a crimp surface. An inner contact located coaxially within the body has a socket contact section at the cable end dimensioned for insertion of the inner conductor of the cable and electrical connection therewith. A body barb located on the outer surface of the body provides an acute surface for heat shrink tubing to seal against.Type: GrantFiled: February 13, 2003Date of Patent: January 11, 2005Assignee: Andrew CorporationInventors: James Wlos, James Krabec

Patent number: 6809686Abstract: A multi-band antenna with a radiator element located between a ring element with a feed leg and at least one ground leg, and a ground plane. The radiator element may be arranged in a substantially parallel orientation with and electrically isolated from the ring element and the ground plane. The antenna elements may be dimensioned for reception of AMPS, UMTS, PCS and SDAR frequency bands. Further, the antenna may include a GPS module.Type: GrantFiled: June 17, 2002Date of Patent: October 26, 2004Assignee: Andrew CorporationInventors: Xin Du, Francisco X. Gomez

Patent number: 6793529Abstract: An electrical connector for coaxial cable, the connector having a positive stop for a clamp nut. The clamp nut driving a means for compression which sandwiches a leading edge of the coaxial cable outer conductor between the connector body and the means for compression. The positive stop positioned to limit tightening of the clamp nut and thereby compression force upon the flared leading edge of the coaxial cable outer conductor to a desired maximum level. The means for compression, for example a circular coil spring may be deformable, allowing the connector to adapt to varying manufacturing tolerances of each connector component, yet still maintaining the maximum desired compression force limit. Thereby, the connector may be correctly installed without requiring use of a torque wrench to ensure proper compression force.Type: GrantFiled: September 30, 2003Date of Patent: September 21, 2004Assignee: Andrew CorporationInventor: Larry Buenz

Patent number: 6788264Abstract: A satellite antenna with a radiator element arranged between a ring element and a ground plane. The radiator element arranged in a substantially parallel orientation and electrically isolated from the ring element and the ground plane. The antenna elements may be dimensioned for reception of SDAR frequency bands.Type: GrantFiled: June 17, 2002Date of Patent: September 7, 2004Assignee: Andrew CorporationInventor: Xin Du

Patent number: 6752649Abstract: A power supply apparatus for coupling electricity between a power source and a device. The apparatus including a body having at least one aperture and at least one electrical contact configured to mate with the power source; at least one light source arranged within the body; and at least one light transmitting cover. The cover configured to cover the at least one aperture. The cover having indicia thereon. The at least one light source arranged to radiate through the at least one aperture and backlight the indicia. Manufacture of the power supply apparatus may be performed in large volumes and desired indicia later added and or changed via the cover, increasing manufacturing efficiency and flexibility.Type: GrantFiled: November 7, 2002Date of Patent: June 22, 2004Assignee: Xentris, LLCInventors: David M. Arkin, Michael Knapp

Patent number: 6686829Abstract: An electronic radio frequency (RF) identification system 10 is disclosed and claimed. The system includes an interrogator 11 and a plurality of RF transponders 12.1 to 12.n. In use, each transponder is operative in response to an interrogation signal 14 to respond with a forward error correctable data message 16.1 including base data encoded as symbol characters in accordance with a forward error correcting code, such as a Reed Solomon Code, and check characters on the base data as defined in the forward error correcting code. The interrogator 11 utilizes data relating to the forward error correcting code, the symbol characters and check characters in the received forward error correctable data message, to reconstruct the base data in the event of corruption of the forward error correctable data message during transmission.Type: GrantFiled: January 19, 1999Date of Patent: February 3, 2004Assignee: ZIH Corp.Inventors: Clive Paul Hohberger, Christopher Gordon Gervase Turner

Patent number: 6683254Abstract: A cable coupler between a trunk cable having a first center conductor and a first outer conductor and a second cable having a second center conductor and a second outer conductor. An aperture is formed in the first outer conductor; a probe having a capacitive element on a first end is inserted into the aperture to contact the first center conductor. A second end of the probe is coupled to the second center conductor. The first outer conductor and the second outer conductor may be coupled together directly or via a second capacitor. A cover may be added to secure the different components and or to provide environmental protection for the cable coupler. The capacitive element may be mounted on an insulating substrate. A range of capacitive elements may be used to achieve a desired coupling between the trunk cable and the second cable.Type: GrantFiled: September 30, 2002Date of Patent: January 27, 2004Assignee: Andrew Corp.Inventor: Robert Gunnels

Patent number: 6660939Abstract: A method and apparatus for forming a cable coupler for coupling a co-axial trunk cable having a trunk outer conductor, to a coupler cable. A channel is formed in the trunk outer conductor; a first coupler conductor is coupled to a first side of the channel; and a second coupler conductor is coupled to a second side of the channel. Alternatively, a trough may be formed and a conductor coupled with one end of a conductor inserted in the trough. Channels or troughs may be pre-formed in a trunk cable creating coupler connection points that may be quickly adapted to form a coupler with minimal field installation requirements. The coupler coupling factor may be varied by electrically shortening the channel or trough with, for example, a conductive ring, conductive foil or a conductive collar.Type: GrantFiled: December 3, 2002Date of Patent: December 9, 2003Assignee: Andrew CorporationInventor: Robert Gunnels
