Publication number: 20120223514Abstract: A conveyance such as a wheelchair that includes a seat assembly and a chassis. The chassis comprises a central frame member disposed substantially along the centerline of the wheelchair. The central frame member includes portions for connecting to or supporting one or more front casters, a seat assembly, one or more drive wheel assemblies, an energy source (e.g., one or more batteries), rear anti-tip wheels, and/or at least one footplate. The central frame member is disposed substantially along the centerline of the wheelchair and structurally distributes of the weight of the seat assembly (and optionally the weight of the energy source) to the supporting drive wheels and casters. In this manner, a clean-looking, simple, and lightweight chassis structure is provided for a conveyance.Type: ApplicationFiled: November 15, 2010Publication date: September 6, 2012Applicant: Invacare Corp.Inventors: Damon Jurkiewicz, Joshua Greiner, Daniel James Yee, Daniel Watson, Traian Mohan, Robert Bekoscke

Publication number: 20110316253Abstract: The present application relates generally to conveyances and, more particularly, to wheelchairs. In one embodiment, a wheelchair includes a seat assembly coupled to a chassis. The chassis includes a frame having a rear wheel support member, one or more front wheel support members extending in a forward direction from the rear wheel support member, and a seat support member. The rear wheel support member comprises a central portion and left and right portions extending downward from the central portion. The wheelchair also includes one or more drive wheels for propulsion of the wheelchair, a set of front wheels for supporting the wheelchair, and a shrouding system for at least partially covering the frame and other components of the wheelchair.Type: ApplicationFiled: June 24, 2011Publication date: December 29, 2011Applicant: Invacare CorporationInventors: Thomas Tuckowski, Traian Mohan, Robert Bekoscke, Damon Jurkiewicz, Daniel James Yee, Joseph Spalding, Howard Loewenthal

Patent number: 8041317Abstract: A system includes a radio frequency transceiver. A baseband processor includes an automatic gain control module. The automatic gain control module has a gain that changes from and subsequently returns to a predetermined value each time the radio frequency transceiver receives a radio frequency signal. The baseband processor is configured to selectively generate an interrupt signal each time a radio frequency signal is received based on a magnitude of the change in the gain of the automatic gain control module and a length of time in which the gain returns to the predetermined value. A control module is configured to identify a radio frequency signal received by the radio frequency transceiver as a radar signal in response to the baseband processor having generated a plurality of interrupt signals at substantially equal time intervals.Type: GrantFiled: October 5, 2009Date of Patent: October 18, 2011Assignee: Marvell World Trade Ltd.Inventors: Milind Kopikare, Hui Yao Lin, James Yee, Chuong Vu

Publication number: 20110227314Abstract: A seat assembly for a conveyance, such as a wheelchair, that allows the user to set the recline angle of the seat back at a seating position, fold the seat back down to a folded position and back up to the seating position, such that the seat back is returned to the seating position at the user selected recline angle R unless the recline angle is adjusted by the user. The user selected recline angle R is not disturbed by folding the seat back from the seating position, to the folded position 106, and back to the seating position.Type: ApplicationFiled: March 16, 2011Publication date: September 22, 2011Applicant: Invacare CorporationInventors: Howard Lowenthal, Traian Mohan, Robert Bekoscke, Damon Jurkiewicz, Daniel James Yee

Publication number: 20110200055Abstract: A Cable Modem Termination System (CMTS) is partitioned into Line Cards, I/O Cards, and a midplane to provide enhanced Reliability, Availability, and Serviceability. Each I/O Card provides a cabling interface for coupling an assigned Line Card to other portions of a Hybrid-Fiber-Coax Network. A plurality of RF signals is coupled via connectors between each Line Card and a corresponding I/O Card, via the midplane. This permits a Line Card to be removed for servicing without requiring recabling of the corresponding I/O Card. Preferably, a rectangular-multi-pin collinear connector-cascade (Line Card jack, midplane double-plug, and I/O Card jack) is used to couple the plurality of RF signals. The connector-cascade is configured with protective RF ground pins adjacent and surrounding each of a plurality of RF signal pins.Type: ApplicationFiled: April 19, 2011Publication date: August 18, 2011Applicant: JUNIPER NETWORKS, INC.Inventors: Valentino LIVA, Alok SHARMA, Lance SMITH, James YEE

Publication number: 20110176457Abstract: A method of configuring an ad-hoc wireless network between an authenticator and a plurality of wireless devices seeking authentication includes assigning a wireless device as the authenticator and receiving a first setup message transmitted from a first device seeking authentication to the authenticator and initiating a first handshake process between the authenticator and the first device seeking authentication. The method also includes receiving a second setup message transmitted from a second device seeking authentication to the authenticator. The second setup message is received by the authenticator prior to completion of the first handshake process. The method further includes initiating a second handshake process between the authenticator and the second device seeking authentication. The second handshake process is initiated prior to completion of the first handshake process. Moreover, the method includes completing the first handshake process and completing the second handshake process.Type: ApplicationFiled: March 21, 2011Publication date: July 21, 2011Inventor: JAMES YEE

Publication number: 20100031305Abstract: Enhanced Cable Modem Termination System (CMTS) functionality, including programmable digital domain modulators and demodulators for dynamic channel assignment, is incorporated into Fiber Nodes (FNs) or mini Fiber Nodes (mFNs), yielding enhanced Fiber Nodes (eFNs). These eFns distribute CMTS functionality deep into Hybrid-Fiber-Coax Networks (HFCN) rather than centralizing the CMTS functions within a single location. Moving the cable modem terminations closer to the subscribers shortens the analog RF paths required to support cable modems. Communication of both subscriber data and CMTS control data is performed over Ethernet-compatible packet networks between the field-based CMTSs and an upstream facility (e.g., the Head End), which includes an Internet gateway. Packet data for multiple subscriber cable modems is easily compressed and merged over common network paths, reducing cabling plant complexity and increasing bandwidth utilization.Type: ApplicationFiled: October 9, 2009Publication date: February 4, 2010Applicant: JUNIPER NETWORKS, INC.Inventors: Valentino LIVA, Alok SHARMA, Lance SMITH, James YEE
