    摘要: In a radio communication system, a relay route is established with a plurality of wireless devices constructing an MPR set for a wireless device as a root node by transmission and reception of a Hello packet. A wireless device other than that constructing the MPR set transmits neighboring wireless device information, information of a neighboring wireless device thereof, to the wireless device as the root node via the relay route. Based on the neighboring wireless device information received via the relay route, the wireless device as the root node generates and stores topology information indicating a topology of a plurality of wireless devices constructing the radio communication system. The wireless device as the root node transmits the topology information to a plurality of wireless devices on a regular basis, or transmits to a wireless device requiring the topology information. As a result, radio communication can be performed with reduced overhead.

    摘要: A source terminal measures characteristics of the path at the source terminal itself, produces a characteristics-measurement packet, and transmits the produced characteristics-measurement packet to a relay terminal. Upon receiving the characteristics-measurement packet, the relay terminal measures characteristics of the path at the relay terminal itself, renews the characteristics of the path included in the characteristics-measurement packet using the measured characteristics of the path, and transmits the characteristics of the wireless communication path to the destination terminal. The source terminal produces an admission-request packet and transmits the packet to the destination terminal. Upon receiving the admission-request packet, the destination terminal allows or rejects the traffic quality maintenance request according to the characteristics of the wireless communication path. The allowance or rejection of the quality maintenance request is transmitted to the source terminal with the admission-reply packet by the destination terminal.

    摘要: A polarization beam combiner/splitter (“PBCS”) for combining and splitting multiple channels of light beams simultaneously is disclosed. The PBCS includes a first fiber array, a second fiber array, and an optical core composed of a birefringent or other suitable material. The first fiber array includes a plurality of optical fiber pairs, while the second fiber array includes a corresponding plurality of optical fibers. The optical core is sized to modify light beams from any of the optical fibers of the first or second array. In a beam combining operation, multiple channels of polarized beams are emitted by the optical fiber pairs of the first fiber array and passed through the optical core, which combines the beams into dual-polarized combined light beams. The combined beams exit the optical core and are received by the second array of optical fibers. A similar beam splitting operation can be performed on multiple combined beams.

    摘要: A device functions as a polarization beam combiner and an isolator. When light is transmitted in a first propagation direction, a second beam is displaced towards a first beam. The second beam has a polarization orthogonal to the polarization of the first beam, and the second beam is substantially parallel to the first beam. The polarizations of the first and second beams are rotated by a same first amount in a first rotation direction and then rotated by the same first amount in a second opposite rotation direction. The first and second beams are combined by displacing the second beam towards the first beam. The combined beam is polarized along a first plane and second plane, which is orthogonal to the first plane. When light is transmitted in a second opposite propagation direction, the device is used to provide optical isolation.

    摘要: A method of testing memory of a system is disclosed which operates the system from a second area of system address space which is outside of a first area of system address space, the system having one or more physical memory devices associated with the first area of system address space. The memory locations associated with the first area of the system address space are tested for predetermined characteristics after which the one or more tested physical memory devices are replaced with respective untested physical memory devices without dropping power to the system, and tested by repeating the test cycle. The system is prevented from operating in the first area of system address space and forced to operate from the second area, thereby preventing system interruptions when replacing the physical memory devices for testing.

    摘要: Double layer, or bi-layer, magnetic films are deposited over a substrate with an underlayer. The bi-layer film is a film of two different magnetic layers which have different chemical composition, deposited with no spacer layer between the two layers. The lower magnetic layer should be of a low noise magnetic material, while the upper magnetic layer should be a high coercivity magnetic material. The bi-layer film exhibits a single response to magnetic recording and a joint coercivity different from the coercivity of either layer by itself. A preferred double layer media uses a CoCrTa layer deposited under a CoCrTaPt layer, with the CoCrTa layer comprising 30 to 70% of the total film thickness. The double layer film produces magnetic media with higher coercivity and lower media noise as compared to single layered films of either of the materials of the magnetic layers.
