Abstract: A method and a system for providing an application to be executed on a plurality of computer systems. The method includes: providing an interface for each computer system, wherein the interface includes at least one application container; and migrating a script of the application into each of the plurality of the computer systems through the corresponding interface, wherein for each interface, the script is executable in the at least one application container of the interface.

Abstract: A socket protector for fixing a protective cover to a housing includes a connecting member and a receiving groove defined in the housing. The connecting member is connected to the protective cover. The connecting member has an elastic connecting portion defining a restricting hole. A restricting portion is formed in the receiving groove. When the elastic connecting portion resists the restricting portion, the elastic connecting portion deforms to extend the restricting portion through the restricting hole of the elastic connecting portion, thus connecting the protective cover to the housing.

Abstract: A pump (10) has a housing (11), a base (12) and a flexible diaphragm (13) between the housing and the base. The diaphragm (13) and the base (12) define a driving chamber and the diaphragm (13) and the housing (11) define a pump chamber. The driving chamber is coupled to a pump driver adapted to direct fluid to and from the driving chamber to drive the diaphragm. The pump chamber is of generally conical form with its outlet (21) being located at the apex of the conical pump chamber and the inlet (22) being disposed at an angle inclined to the plane of the base of the conical pump chamber and being generally tangential to the outer portion of the base of pump chamber such that flow through the pump chamber is in the form of a continuous spiral vortex.
