摘要： A speaker system includes a first array of transducers in a speaker enclosure and, and at least a second array of transducers in the speaker enclosure. The second array is a low-frequency array and the first array is a high-frequency array. The transducers in the first array are configured to have an operating frequency region covering at least the frequency ranges of the first array and the second array, and the transducers in the second are configured to have an operating frequency region covering at least the frequency ranges of the first array and the second array. The speaker system further includes an input port, and a controller operatively coupled with the input port. The controller is configured to provide an electronic-audio signal to the transducers such that the first array and the second array are tuned to different center frequencies and are a two stage dipole beamforming array.

摘要： In a radio access network (10) comprising a radio network controller node (26) and a base station node (28), a code tree has spreading codes which are allocatable between high speed downlink shared (HS-DSCH) channels and dedicated (DCH) channels. According to one aspect of the technology, use of the spreading codes of the code tree is monitored and an HS-DSCH channel is allocated a free spreading code which is non-adjacent to a spreading code already allocated to the HS-DSCH channels. In some example implementations, the free, non-adjacent spreading code is allocated so that more than one high speed channel user can use the spreading codes. In other example implementations, the free, non-adjacent spreading code is allocated so that one user uses the spreading codes by using more than one HS-SCCH channel. Preferably the non-adjacent spreading code is released from the HS-DSCH channel when the non- adjacent spreading code is needed for use by a DCH channel.

摘要： The inventors have envisioned a multihop network scenario in which nodes are equipped with advanced multi-antenna arrangements, and recognized the advantage of exploring the presence of such advanced antenna arrangements in multihop network nodes for the specific purpose of determining link cost for routing in the network. A basic idea of the invention is therefore to determine link cost for a wireless link between a pair of nodes in the network based on multi-channel characteristics between the nodes, where at least one of the nodes is configured for operation with multiple antennas to provide for multiple channels. These multi-channel characteristics may for example be determined based on explicit channel matrix estimation and/or the number of transmit and receive antennas or other information on the antenna capabilities of the involved nodes. The determined link cost information may subsequently be used together with additional routing cost information for route determination, and packet forwarding.

摘要： Melt extrudable grafts of emulsion polymerized silicone rubber and polyacrylate rubber hybrids have been found to be valuable impact modifiers for organic thermoplastic polymeric materials. Optimum impact modifier properties are achieved by employing as a source material, an emulsion polymerized silicone rubber made under semi-continuous, low shear process conditions.
