Abstract: A waveguide (1) comprising a shell (11, 12) having an inlet opening (110, 120) intended to receive acoustic energy and an outlet opening (111, 121) for emitting acoustic energy; and a phase plug (13, 14) located into the shell (11, 12) so as to define therebetween a pathway (W) for the acoustic energy from the inlet opening (110, 120) to the outlet opening (111, 121). The acoustic pathway (W) has a longitudinal extension direction (D) between the openings (110, 120, 111, 121) and the directions of all longitudinal splines (S1, S2, S3, S4, S5, S6) of the pathway (W) are perpendicular to the inlet opening (110, 120) at the inlet opening (110, 120) on one ideal longitudinal surface.

Abstract: A device and method of driving multi-Packet Data Protocol (PDP) data communication for a mobile broadband device are disclosed.

Abstract: A driver management method and apparatus for a Mac system are provided. The method includes: receiving a driver file uninstallation instruction of a current device; determining whether the driver file is installed only in the current device among devices without uninstalling the driver files according to the driver file uninstallation instruction; if yes, uninstalling the driver file; if no, reserving the driver file. The method and apparatus solves a compatibility problem of multiple devices sharing a driver file very well. When the current device needs to uninstall the driver file, it is ensured that other devices that need to load the driver file can normally load and use the driver file, thereby avoiding the occurrence of the condition of the drive conflict resulted from the erroneous deletion of the driver file.

Abstract: A device and method of driving multi-Packet Data Protocol (PDP) data communication for a mobile broadband device are disclosed.

Abstract: The present invention discloses a universal driving method and a driver of a mobile broadband device. The method includes: a WWAN server sending an OID service request to a driver; the driver sending the OID service request to a WWAN device; the WWAN device responding after parsing the OID service request, and sending a response result to the driver; the driver sending the response result to the WWAN server. The present invention is implemented by delivering the parse processing of the OID service to the WWAN device, and the driver only has a transparent transmission function, therefore the driver is universal and is able to adapt to WWAN devices in different standards; the AT module is deleted, and it's I/O function utilizes the existing reading and writing threads, thus simplifying the complex process in the existing AT module, and guaranteeing the stability and robustness of the device drivers.

Abstract: An implementation method, an operation method and a system of a data card driver free installation are provided. The implementation method includes following steps. Device side software of a data card is taken as a compound device with a HID function interface. The device side software of the data card maps all of other function interface data of the data card into the HID function interface, and takes the HID function interface as a channel so as to interact data with a PC side. An operating system of the computer automatically obtains and runs green software built in a storage area of said data card.

Abstract: Methods for producing corn with increased transformability are provided. Markers for increased transformability are provided as well as their use to obtain corn plants with increased transformability. Locations on chromosomes that effect transformation efficiency of monocots are identified.
