Publication number: 20030027597Abstract: A method and apparatus for reducing the cost of an RF base station that services a location where real estate is expensive without reducing the capacity of the system, subjecting the system to significant environmental interference, or purchasing additional licensed frequency spectrum. In accordance with the present invention, communication between two sections of an RF base station of a wireless communication system is implemented using an over-the-air optical link, also referred to as a wireless optical link. In particular, wireless RF communication equipment of either, or both, 1) the RF antenna and RF hardware, and 2) the processing and/or control section of the RF base station is coupled to over-the-air optical communication equipment. Overall, the present invention allows an RF base station to service the location where real estate is expensive at a much lower cost without reducing the capacity or the signal quality of the system.Type: ApplicationFiled: July 31, 2001Publication date: February 6, 2003Inventors: James T. LaGrotta, Richard Thomas LaGrotta

Patent number: 6477361Abstract: On instructions obtained from a subscriber, a wireless terminal service provider sends a power-down signal to a wireless terminal. Upon receipt of the power-down signal, the wireless terminal goes into a sleep state. In this state, all monitoring functions other than time, date and elapsed time are turned off. The power-down signal sets a clock, which can be located within the wireless terminal, to awaken the wireless terminal at the end of a discrete interval of time by powering-up the monitoring circuits. The wireless terminal service provider, by knowing the power-down/power-up time cycle of the wireless terminal, can alert a party attempting to contact the wireless terminal during the power-down period that the called party cannot be reached.Type: GrantFiled: May 23, 2000Date of Patent: November 5, 2002Assignee: Lucent Technologies Inc.Inventors: Richard Thomas LaGrotta, James T LaGrotta

Patent number: 6315597Abstract: A power connector for receipt and releasable engagement with a wire to effect a transmitting power electrical connection to the wire. The power connector includes a connector housing having a wire insertion side with an opening for receiving the wire. A spring contact is disposed within the housing and includes an attachment end for attaching the spring contact to the connector housing and a contact end for contact with the wire. The spring contact includes a substantially C-shaped segment extending between the attachment end and contact end. The C-shaped segment is dimensioned to be maintained under compression and so that the spring contact applies a contact force against an inserted wire at the contact end with a force sufficient for supporting the conducting of electricity between the wire and contact end.Type: GrantFiled: December 16, 1999Date of Patent: November 13, 2001Assignee: Lucent Technologies Inc.Inventors: James Christopher Coyne, James T. LaGrotta, Richard Thomas LaGrotta

Patent number: 6213578Abstract: A mounting assembly includes a metallic base member, such as a wall of an enclosure. A threaded stud is fused to the base member. A threaded collar engages the threaded stud and provides a threaded recess for receiving a mounting fastener. The mounting assembly is well-suited for supporting electronic items within an enclosure in a weather-tight or water-proof manner because the mounting assembly requires no seals for an environmental barrier.Type: GrantFiled: August 11, 1999Date of Patent: April 10, 2001Assignee: Lucent Technologies Inc.Inventors: Richard Thomas LaGrotta, James T. LaGrotta, Manuel G. Orellana

Patent number: 6201221Abstract: A heating/cooling apparatus for electronic components of a wireless base station is described. The apparatus includes a heat exchanger having a material-filled chamber and a plurality of extrusions. The chamber is located adjacent to the electronic components. A heater is provided within the chamber. The material within the chamber, which is preferably a liquid, serves to conduct heat from the electronic components to the extrusions. The heater serves to heat the material within the chamber, which in turn conducts that heat to the electronic components, when heat is required to maintain operation of the components with prescribed parameters.Type: GrantFiled: September 16, 1999Date of Patent: March 13, 2001Assignee: Lucent Technologies, Inc.Inventors: James T. LaGrotta, Richard T. LaGrotta

Patent number: 6151757Abstract: A lockable piano-type hinge assembly including a locking hinge piece in addition to two hinge pieces which include the hinge pin barrels. The hinge pin is secured to the locking hinge piece which has an opening aligned with a locking loop secured to one of the hinge pieces. When the hinge assembly is assembled, the locking loop extends through the opening of the locking hinge piece and a locking device is insertable through the locking loop to prevent relative movement of the locking hinge piece and removal of the hinge pin from the barrels.Type: GrantFiled: February 23, 1999Date of Patent: November 28, 2000Assignee: Lucent Technologies Inc.Inventors: Harry C. Beals, Jr., James T. LaGrotta, Richard T. LaGrotta, Ronald B. Walsh, Jr.

Patent number: 6105875Abstract: Outdoor, electronic component containing cabinets are cooled by forced circulation of outside air through the cabinet for direct, cooling contact with the components. The incoming air is filtered, heated as necessary to evaporate water droplets in the air prior to entry of the air into the component containing portions of the cabinet, and the air flow is regulated for slowing the flow rate of the air within the cabinet as is necessary for maintaining the relative humidity within the cabinet below a maximum percentage; typically 40%.Type: GrantFiled: September 8, 1998Date of Patent: August 22, 2000Assignee: Lucent Technologies, Inc.Inventors: James T. LaGrotta, Richard T. LaGrotta

Patent number: 6095482Abstract: A structure on which various equipment, particularly outdoor electronic cabinets, can be mounted comprises a shallow, box-like frame including rigid sides, bottom plates secured to the sides, and cross braces extending between and secured to opposite sides. For rigidity and strength, the cross braces comprise U-beams having upper and lower laterally extending flanges, the upper flanges serving as horizontal surfaces for the mounting of equipment on the support. In a preferred use, the support structure is placed on the ground at a cleared outdoor site and locally available ballast is loaded into the structure for firmly anchoring it in place.Type: GrantFiled: September 14, 1998Date of Patent: August 1, 2000Assignee: Lucent Technologies, Inc.Inventors: James T. LaGrotta, Richard T. LaGrotta

Patent number: 5991145Abstract: An EDS tester is combined with an employee identifier and recording monitor so as to provide and audit trail of compliance with the fact of ESD testing and, if desired, a record of the ESD test results such as body resistance or charge. In one illustrative embodiment, a fingerprint identifier pad is used together with the ESD test to identify a unique biological characteristic of the worker being tested. In addition, the feature of providing physical contact with the workers body typically required for ESD testing may be combined with the fingerprint identifier pad thereby enabling the ESD test results to be correlated with a specific individual.Type: GrantFiled: August 24, 1998Date of Patent: November 23, 1999Assignee: Lucent Technologies Inc.Inventors: James T. Lagrotta, Richard T. Lagrotta

Patent number: 5608159Abstract: A freeze device for an elongated element includes a pressure vessel disposed about at least a part of the element and a freeze seal between the part of the elongated element and the pressure vessel. The freeze seal includes a frozen material exerting a force inwardly against the part of the element and outwardly against the pressure vessel by virtue of having been frozen in situ such that the frozen material thereby seals the elongated element to the pressure vessel.Type: GrantFiled: April 5, 1995Date of Patent: March 4, 1997Assignee: Lucent Technologies Inc.Inventors: John M. Carcone, Jon W. Engelberth, James T. LaGrotta, Joseph V. Newell
