The present invention relates to methods and system for providing telecommunications services, such as call waiting, three-way call, and automatic recall, utilizing a plurality of state machines. Logic specifications define a set of states for each state machine. Each state in turn defines at least one action to be performed in response to a signal received by the state machine. The logic specification for each state machine can be stored, for example, in a textual format in a mark up language, such as HTML, XML, or or other markup language. A compiled representation of the logic specification is generated. Further, a context object tracks a current state of the telecommunication service. The context object accesses the compiled representation in response to an event, e.g., a call progress event, in order to effect a state transition and/or perform an action with respect to the telecommunication service.

A first split-bracket is joined to a first tube-shaped frame by lazar welding. A second split-bracket is joined to an end portion of a second tube-shaped frame by the lazar wielding. The second tube-shaped frame equipped with the second split-bracket is assembled to the first tube-shaped frame equipped with the first split-bracket. A second flange of the first split-bracket and a second flange of the second split-bracket are joined temporarily by spot welding. The second flange of the first split-bracket and the second flange of the second split-bracket are joined by continuous welding with lazar welding. Accordingly, the tube-shaped frames can be connected properly without forming any hole at a wall of the tube-shaped frame, ensuring the rigidity of the connection portion of the tube-shaped frames.

This invention provides an optical imaging lens assembly comprising five lens elements with refractive power, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface; a second lens element with negative refractive power; a third lens element with negative refractive power; a fourth lens element with negative refractive power having at least one of the object-side and image-side surfaces thereof being aspheric; and a fifth lens element having a concave image-side surface, at least one of the object-side and image-side surfaces thereof being aspheric, and made of plastic. By such arrangement, photosensitivity and total track length of the optical imaging lens assembly can be reduced, and the aberration and astigmatism of the assembly can be effectively corrected. Moreover, high image resolution can be obtained.

The invention relates to a coaxial connector (1), comprising a first and a second connector part (2, 3) and an adapter (4) arranged therebetween. The first and the second connector part (2, 3) include a first inner conductor (5) and a first outer conductor (8), including a first internal cylindrical contact surface (24) and a second internal cylindrical contact surface (25), respectively. In a socket area (17) of the first inner conductor (5), a first mechanical operative-connection means interacts with a second mechanical operative-connection means (11) in the installed state in order to establish a mechanical connection (13) that is effective in the axial direction (z). The first inner conductor (5) protrudes beyond the level of the mechanical operative-connection means (10, 11) so the internal cylindrical contact surface (24) is able to compensate a large axial offset (dz) of the connector parts (2, 3) relative to the adapter (4).

A flexible workpiece assembling method for assembling a flexible workpiece (W) with an object by using a first robot comprising a first hand and a second robot comprising a second hand includes the steps of: gripping a first portion of the flexible workpiece by the first hand and gripping a second portion of the flexible workpiece different from the first portion by the second hand; moving the flexible workpiece to the object through a cooperating operation of the first and second robots; deforming the flexible workpiece into a shape corresponding to the nonflexible object by the first and second robots; and assembling the flexible workpiece onto the nonflexible object by the first and second robots. As a result, the flexible workpiece can be accurately assembled onto the nonflexible object without breaking or tearing. The first and second robots may comprise a pushing means for pushing the flexible workpiece into the object.
