The present invention discloses a combined dry sorting bed, the sorting bed is arranged with an inclination, and the inclination between the longitudinal extending of said bed surface and horizontal plane is from −2° to +4°, and the inclination between the lateral extending of said bed surface and horizontal plane is from 0° to +15°. By reasonable setting of the angle of inclination, the material being separated spiral overturn continuously on the sorting bed under the influence of the rising air currents and the force of vibration, with the result that the light material in the upper layer is separated under the influence of weight. The material is sorted for many times during the circularly movements, the product with different content of ash can be obtained. This invention also relates to a combined dry sorting device that comprises frame, sorting bed, vibrator and air supply device. This invention further relates to an apparatus for separation that comprises a feeding device, an air supply and dedusting device and a separating device, the above mentioned sorting bed is used in the sorting device and apparatus, therefore different products with vary quantity of ash are generated according to the gravity of material, and the accuracy of separation is improved.

A method for transmitting control information from multiple base stations in an active set to a mobile device in a wireless communication system reduces resource consumption by routing information originating from a plurality of active base stations through a single serving base station. The serving base station pools and resolves the information from the active base stations and sends the resolution of the pooled information over a downlink control channel for evaluation and response by the mobile device.

Techniques for generating preamble sequences for OFDM and OFDMA communication systems based on CAZAC sequences with desired properties of constant amplitudes (CA) and zero autocorrelation (ZAC). Such preamble sequences may be used for synchronization and identification of individual transmitters. For example, the OFDMA symbol is constructed using a CAZAC sequence in the frequency-domain and the resulting time-domain waveform is a near-CAZAC sequence.
摘要:
A method of identifying the available Walsh code space. The method includes at least one wireless unit receiving a Walsh code-based signal. The Walsh code-based signal may be transmitted by a base station, for example. The Walsh code-based signal may be realized by 13 bits, for example, corresponding to indices in a look-up table within the mobile unit that should not be employed. Thereafter, the wireless unit may determine the remaining Walsh code space. This determination step may include ascertaining which indices in the look-up table are relevant, and thusly, removing irrelevant indices. Subsequently, the step of determining the remaining Walsh code space may include examining the Walsh Table ID signal received from the base station to identify the remaining Walsh codes space.

A proton conducting polymer electrolyte comprising a proton conducting ionomer cross-linked with an amount of a copolymer additive comprising cross-linking functional groups and other functional groups (e.g. proton carriers, chelating agents, radical scavengers) shows improved durability over the ionomer alone and provides for more stable inclusion of these other functional groups. The copolymer additive comprises at least two types of metal oxide monomers, one having cross-linking functional groups and the other having the other functional groups.
