    摘要： A floatable lounger includes a first buoyancy means; second buoyancy means spaced from said first buoyancy means; first and second extending means; and headrest rotatable about said first extending means between a first stored position and a second operable position. The floatable lounger provides for a simpler construction for a floating lounger with excellent buoyancy.

    摘要： A flexible connector includes a unitary connector block having first and second board-facing areas. The first and second board-facing areas are longitudinally spaced from each other on a chosen surface of the connector block. The connector block includes a block body transversely separating the chosen surface from an opposing surface oppositely facing from the chosen surface. The connector block includes a flexible connector bridge longitudinally interposed between the first and second board-facing areas. A first connector port is located within the first board-facing area. A second connector port is located within the second board-facing area. A connector trace extends through at least a portion of the block body between the first and second board-facing areas. The connector trace electrically connects the first and second connector ports. Methods of making and using the flexible connector are also included.

    摘要： An apparatus includes a top conductive layer of on an integrated circuit waveguide filter and a bottom conductive layer. The top and bottom conductive layers are coupled via a plurality of couplers that form an outline of the waveguide filter. A dielectric substrate layer is disposed between the top conductive layer and the bottom conductive layer of the integrated circuit waveguide filter. The dielectric substrate layer has a relative permittivity, εr that affects the tuning of the integrated circuit waveguide filter. At least one tunable via includes a tunable material disposed within the dielectric substrate layer and is coupled to a set of electrodes. The set of electrodes enable a voltage to be applied to the tunable material within the tunable via to change the relative permittivity of the dielectric substrate layer and to enable tuning the frequency characteristics of the integrated circuit waveguide filter.

    摘要： A downstream adaptive modulation system and method. The downstream adaptive modulation system comprises a wireless access termination system and one or more wireless modems. The wireless access termination system includes a plurality of queues and a parser. The parser parses data traffic onto the plurality of queues. Each queue is associated with a different coding and modulation scheme. Each of the one or more wireless modems receives data traffic from the plurality of queues based on the wireless modem's ability to demodulate and decode the signal from each of the plurality of queues. When a wireless modem experiences a change in signal strength, the present invention enables the wireless modem to adapt to data from other queues to compensate for the change in signal strength. Thus, if the signal strength improves over a period of time, the wireless modem may receive data at a higher order modulation and FEC code rate. If the signal strength weakens over a period of time, the wireless modem may receive data at a lower order modulation and FEC code rate.

    摘要翻译： 一种下行自适应调制系统及方法。 下行自适应调制系统包括无线接入终端系统和一个或多个无线调制解调器。 无线接入终端系统包括多个队列和解析器。 解析器将数据流量分析到多个队列上。 每个队列与不同的编码和调制方案相关联。 一个或多个无线调制解调器中的每一个基于无线调制解调器解调和解码来自多个队列中的每一个的信号的能力，从多个队列接收数据业务。 当无线调制解调器经历信号强度的变化时，本发明使得无线调制解调器能够适应来自其他队列的数据以补偿信号强度的变化。 因此，如果信号强度在一段时间内改善，则无线调制解调器可以以较高阶调制和FEC码率接收数据。 如果信号强度在一段时间内衰减，则无线调制解调器可以以较低阶调制和FEC码率接收数据。

    摘要： A system includes a broadcast overlay network including a ring topology. The ring topology includes a first network ring and a second network ring that is coupled to the first network ring via at least one cross-connect element. The ring topology is adapted to carry broadcast traffic from a network. The system also includes a digital subscriber line access multiplexer (DSLAM) having a line interface and a network interface. The network interface is in communication with the broadcast overlay network via the second network ring. The DSLAM is adapted to receive a request for a particular video channel from a customer premise via the line interface and to deliver the particular video channel from the network interface to the line interface.
