Publication number: 20110294313Abstract: A receptacle connector is provided for mounting on a printed circuit having a contact mounting area and an incoming trace that extends into the contact mounting area. The receptacle connector includes a housing having a slot configured to receive a mating connector therein. The receptacle connector also includes an upper contact and a lower contact held by the housing. The upper and lower contacts include mating segments, mounting feet, and intermediate segments that extend between the mating segments and the mounting feet. The mounting foot of the lower contact is configured to be mounted on the incoming trace of the printed circuit such that the mounting foot creates a conductive path between the incoming trace and the intermediate segment of the lower contact. The conductive path forms part of a propagation path of electrical current through the electrical trace and the lower contact.Type: ApplicationFiled: May 26, 2010Publication date: December 1, 2011Applicant: Tyco Electronics CorporationInventor: Michael Frank Cina

Patent number: 7967614Abstract: A plug connector having a plug body including a board substrate. The board substrate has at least one engagement surface that is configured to interface with mating contacts of a receptacle connector. The plug connector also includes a plurality of differential pairs that extend along the board substrate. The differential pairs include conductive pathways that have contact pads located on said at least one engagement surface. The contact pads are configured to electrically engage the mating contacts of the receptacle connector. The conductive pathways of at least one differential pair form a cross-over such that the conductive pathways of the plurality of differential pairs have a first arrangement with respect to each other before the cross-over and a different second arrangement after the cross-over. The first and second arrangements generate first and second crosstalk components, respectively, that are configured to offset one another.Type: GrantFiled: April 28, 2010Date of Patent: June 28, 2011Assignee: Tyco Electronics CorporationInventors: Michael Frank Cina, Randall Robert Henry, Linda Ellen Shields

Patent number: 7794241Abstract: A pluggable module for mating with a receptacle connector of a host device. The pluggable module includes a housing having a front and a rear, a circuit board held by the housing that includes a mating edge and a plurality of contact pads arranged at the mating edge, and a straddle mount connector coupled to the mating edge of the circuit board. The straddle mount connector includes a plurality of contacts engaging corresponding contact pads. The contacts extend between a termination end coupled to the contact pads and a mating end configured to engage corresponding contacts of the receptacle connector. The straddle mount connector also includes a dielectric connector body having a platform for supporting the contacts. The platform includes a plurality of dividers between each of the contacts, where the dividers define a plurality of channels that receive the contacts. The dividers extend from the platform beyond the contacts such that the contacts are recessed below an outer surface of the dividers.Type: GrantFiled: January 14, 2009Date of Patent: September 14, 2010Assignee: Tyco Electronics CorporationInventors: Edward John Bright, Michael Frank Cina

Patent number: 7674133Abstract: A connector assembly includes a housing and a contact module assembly including first and second contact modules loaded into the housing. The first contact module has a plurality of ground leads extending between mating contacts and mounting contacts. The ground leads extend along separate paths within a first plane. The second contact module has a plurality of signal leads extending between mating contacts and mounting contacts. The signal leads extend along separate paths within a second plane. The ground leads are aligned with the signal leads in a direction transverse to the first plane, and the ground leads have a width and a thickness defining a cross-sectional area that is larger than a cross sectional area of the signal leads.Type: GrantFiled: June 11, 2008Date of Patent: March 9, 2010Assignee: Tyco Electronics CorporationInventors: Michael Warren Fogg, Michael Frank Cina

Patent number: 6128510Abstract: A cordless modem comprises a radio pair interfaced to a standard data/fax modem which allows a user of a personal computer to wirelessly connect to a telephone line. One end of the radio pair is a remote unit interfaced to the modem contained within the PC while the other end is a base unit connected to a standard telephone wall jack. The base unit can selectively discriminate and adjust for signals received from a telephone voice handset or data signals received from the cordless modem remote unit. Upon receiving an off-hook signal or an incoming call signal, the base unit identifies the type of data (i.e., voice or computer modem data) and adapts accordingly by placing an FM modulator in either of a narrow band deviation or a wide band deviation covering the required range of the particular signal combined with local echo. That is, when voice data is present, a low deviation, narrow filter combination is selected.Type: GrantFiled: May 13, 1997Date of Patent: October 3, 2000Assignee: International Business Machines CorporationInventors: Troy James Beukema, Michael Frank Cina, Ephraim Bemis Flint, Brian Paul Gaucher, Young Hoon Kwark, Modest Michael Oprysko, William Edward Pence, Saila Ponnapalli

Patent number: 6009247Abstract: A portable or notebook type computer communication interface that permits portable computers to be reliably used in a data processing network. The interface involves communication circuitry, special device inputs and power monitoring and charging. A flexible portable computer wireless time and frequency division network is formed using a time and frequency division multiplexed communication channel assignment feature that together with a wireless link establishes a unique direct communication channel between data processing devices on different levels with data packet type transmission security. The principle permits each portable computer in the network to communicate with any other and any and all can transmit and receive at the same time.Type: GrantFiled: October 29, 1996Date of Patent: December 28, 1999Assignee: International Business Machines CorporationInventors: Frank J. Canora, Michael Frank Cina, Brian Paul Gaucher, Paul Francis Greier, Richard Ian Kaufman, Alphonso Philip Lanzetta, Lawrence Shungwei Mok, Robert Stephen Olyha, Saila Ponnapalli, John LeRoy Staples

Patent number: 5937348Abstract: A cordless modem comprises a radio pair interfaced to a standard data/fax modem which allows a user of a personal computer to wirelessly connect to a telephone line. One end of the radio pair is a remote unit interfaced to the modem contained within the PC while the other end is a base unit connected to a standard telephone wall jack. This arrangement allows the user the convenience and freedom of using a PC, laptop, personal digital assistant, etc., within several hundred feet of a phone jack without being encumbered by a cord. A warning alarm on the remote unit informs the user when the signal strength between the radio pair is below a threshold value. Additionally, the base unit may be equipped with two spatially separated antennas to help mitigate the effects of signal fading.Type: GrantFiled: January 23, 1996Date of Patent: August 10, 1999Assignee: International Business Machines CorporationInventors: Michael Frank Cina, Ephraim Bemis Flint, Brian Paul Gaucher, Young Hoon Kwark, Modest Michael Oprysko, William Edward Pence, Saila Ponnapalli
