Title: A damper assembly having an air flow control regulator
IPC: F24F11/75
Filed: 1978-11-27
Abstract: A regulator for a damper assembly operable to control the flow of conditioned air through a supply duct. The regulator includes a pressure responsive member connected to the damper assembly to vary the position thereof within the supply duct in accordance with changes in the conditioned air supply pressure to maintain a substantially constant volume air flow downstream of the damper assembly irrespective of such changes.

Title: Method and Device for Automatic Conflict Discrimination of PBN Instrument Flight Procedures in Terminal Areas
Inventor: PAN WEIJUN
IPC: G08G5/04
Filed: 2021-05-25
Granted: 2021-11-25
Abstract: A method and device for automatic conflict discrimination of PBN instrument flight procedures in the terminal area, comprising the following steps : retrieving route data of all route segments; traversing all route segments, extracting those with intersections, and finding the intersections between intersecting route segments; then deducing the altitudes of the two endpoints of the two intersecting route segments respectively; finally judging whether the spacing between two intersecting route segments at the intersection is less than or equal to the set threshold. If so, it is judged to be in conflict; otherwise, it is judged to be conflict-free. The application of the method and the device provided by the invention can significantly improve the working efficiency of programmers, reduce the workload of programmers and reduce the human error rate, while the visualization of flight procedures can intuitively and quickly provide control staff with a reference means for potential conflict analysis.

Abstract: A multi-level layered cellular radio architecture serves mobile subscriber stations moving within the system. Best server selection is performed for the mobile stations by assigning within each cell a preference value to each other one of the cells with which is associated by proximity of service area. The strength of the radio signal received by the mobile from the serving cell as well as the radio channels of associated cells is measured. A decision as to the best serving cell for the mobile station is made based upon both the preference value of the associated cells and the signal strength of their respective radio channels.

Abstract: Techniques for Walsh space assignment are disclosed. In one aspect, a list of Walsh functions is maintained in the base station (104) and mobile stations (106). A Walsh space indicator is transmitted to indicate which of the Walsh functions on the list are to be used in communication. The Walsh space indicator is updated according to the dynamically varying transmit power available or the use of Walsh functions within the base station. Methods by which a mobile station can request Walsh space information are provided. In another aspect, a Walsh space indicator channel is continually broadcast for mobile stations to detect the Walsh space indicator therefrom. In yet another aspect, the Walsh space indicator is used to initialize convolutional encoders (260) and decoders (304), to provide a mechanism for mitigating against errors introduced while receiving Walsh space indicators.; Various other aspects are also presented.
