Abstract: This application discloses a data transmission method and an apparatus. The method includes: A base station sends configuration information to UE. The UE receives the configuration information, where the configuration information includes an association relationship between a first SRS configuration and one or more PUSCH configurations, and a first BWP in which the first SRS configuration is located is different from a BWP in which each PUSCH configuration is located. The UE sends a first SRS on the first BWP based on the first SRS configuration, and sends a first PUSCH based on a first PUSCH configuration, where the first PUSCH configuration is one of the one or more PUSCH configurations. Correspondingly, the base station receives the first SRS based on the first SRS configuration, and receives the first PUSCH based on the first PUSCH configuration.

Abstract: Redundant Layer 2 Domain Interconnection may be provided. First, a first device in a first domain may be designated as an active device in response to the first device in the first domain negotiating with a second device in the first domain. The first device in the first domain may be connected to a first device in a second domain. The first domain may use a first protocol and the second domain may use a second protocol. Next, the first device in the first domain in response to being designated as the active device, may allow data traffic to pass between the first device in the first domain and the first device in the second domain. Then the second device in the first domain may be designated as a standby device in response to the first device in the first domain negotiating with the second device in the first domain. The second device in the first domain may be connected to a second device in the second domain.

Abstract: A method of forming an object by powder injection molding, the object being formed from an injection molded integral body comprising a green part contiguous with an expendable part, the method comprising debinding the integral body at step 18 to obtain a debound green part contiguous with a debound expendable part; sintering the debound green part at step 20 at a sintering temperature, the debound expendable part configured to at least partially define the debound green part and has a melting point higher than the sintering temperature; and separating the debound expendable part from the sintered debound green part at step 22 to form the object.

Abstract: An alloying system for preparing a titanium alloy, the system comprising a rotating mill to mechanically alloy a mixture of elemental powders in predetermined proportions, the elemental powders including titanium particles, alpha stabilizer particles and beta stabilizer particles; wherein the mixture is mechanically alloyed using low impact energy to layer the titanium particles with beta stabilizer particles whereby sintering of the mechanically alloyed mixture produces alternate layers of alpha and beta stabilizer particles.

Abstract: Metal-metal or metal-ceramic/carbide composite materials are fabricated by combination of powder injection molding and infiltration. This is achieved by first forming a composite system having a matrix component and an infiltrant layer. The matrix component is formed from a metal or ceramic/carbide powder, that is of a higher melting point, admixed with a first binder. The infiltrant layer is formed from a metal powder, that is of a lower melting point, admixed with a second binder. The first and second binders are subsequently removed from the composite system during a debinding process. The composite system is then heated in a sintering furnace to coalesce the matrix component into a matrix phase having a network of interconnected pores, and to effect infiltration of the infiltrant layer into these pores to form the composite material of the present invention.

Abstract: A flow control device for a data storage system to reduce flow induced vibration. The flow control device includes a plurality of streamline flow passages to reduce turbulent flow in a flow field along a disc surface. Thus, air flow induced by rotation of data discs is directed through the plurality of streamline flow passages to reduce turbulence to limit excitation or vibration of the head and suspension components.

Abstract: A shroud mounted to the housing of a disc drive blocks wind to the arm and suspension that positions a slider adjacent a recording surface of a disc. A first wall has a windward surface facing into the direction of rotation of the first disc. A second wall extends downwind from the windward surface between the arm and the disc to from a low-wind region with the first wall. The region is open at the leeward side so that the arm in the low-wind region positions the slider adjacent the disc. In some embodiments, a third wall is parallel to the second wall so that the low-wind region is a slot.
