  • Patent number: 8599789
    Abstract: Within both the licensed and unlicensed wireless spectrum, benefits are obtained in allowing devices to form and communicate based upon opportunistic spectrum availability. At present such ad-hoc networks are established using either directly existing Media Access Control protocols or proposing modifications to them. According to the invention, there is provided a method for allowing abstract wireless links, i.e., arbitrary cooperation among a set of proximite wireless nodes, to be established between devices in a fast and efficient manner. Beneficially the approach allows multi-standard cognitive radios to operate in ad-hoc environments and non-ad-hoc environments. Accordingly a wireless module monitors a plurality of sensing tones and polling tones, each pair of sensing and polling tones associated with a transmission channel. A wireless module determines a vacant transmission channel by the absence of both a sensing tone and its associated polling tone.

The special device has an effective grating region (1). The effective grating region (1) has a middle zone (2) and two side zones (3, 4); the middle zone (2) has two side edges which are parallel and equal in length, and the two side edges has a distance therebetween which is 10-90% of diameter of the effective grating region (1), and the middle zone (2) and the two side zones (3, 4) have different grating pitches.

  • Patent number: 7760649
    Abstract: The invention relates to opportunistic wireless mesh networks which operate under random networking conditions. Such random network conditions typically limit the effectiveness of prior art wireless mesh networks, and more particularly to those supporting low power devices within the wireless network. Random network conditions include: random power supply, random node distribution, random node mobility, high mobility of nodes, random wireless link fluctuations, and random application traffic. The opportunistic wireless mesh network utilizes a two-layer architecture Embedded Wireless Interconnect (EWI) framework, which is adopted as the architecture reference model. A mesh network according to the invention supports opportunistically determining both mesh interconnections and network transmission routes by providing nodes with broadcast modules and unicast modules.

  • Publication number: 20070172387
    Abstract: An analytical instrument includes an instrument body having a multiple external-device interfaces for connection with external devices, and a housing that covers the instrument body. The housing includes a housing panel having a first opening exposing the external-device interfaces and a plug structure having a first plug and a second plug. The first plug rotatably fits into the first opening and includes a second opening that exposes one of the external-device interfaces. The second plug is smaller than the first plug and is removably fitted into the second opening to close the second opening when no external device is connected to any of the external-device interfaces. When an external device is to connect to one of the external-device interfaces, the second plug is removed from the second opening and the first plug is rotated to expose the intended one of the external-device interface through the second opening.
