摘要:
An approach is provided for performing multiple and hybrid forms of communication in the same communication session. A communication manager receives a to establish a communication session using a first form of communication, wherein the communication session supports multiple and simultaneous forms of communication. Next, the communication manager selects a second form of communication to conduct the communication session. Then, the communication manager transcodes the second form of communication to the first form of communication. The different forms can be converted to facilitate and enrich the communication capability, according to an embodiment of the invention.

A limited free-motion coupling device 10 coupling an impeller 14 to a shaft 16 of a rotor 12, the coupling device 10 comprising first and second parts 20, 22 which are axially engaged for relative angular displacement about a rotational axis A, and two spherical coupling members 24 for engaging the first and second parts 20, 22 to prevent the relative angular displacement. One of the first and second parts 20, 22 is provided on the shaft 16 of the rotor 12, and the other is provided on the impeller 14. The first part 20 comprises two spaced coupling member arms 30 which project radially. The second part 22 comprises a cylindrical wall 66 extending coaxially with the rotational axis A of the coupling device 10. Two spaced arcuate channels 50 are formed in the cylindrical wall 66. Each coupling member 24 is received in and projects radially from a respective arcuate channel 50, and is freely movable between end walls of the arcuate channel 50. As the first part 20, rotates relative to the second part 22, the coupling member arms 30 of the first part 20 engage and move the coupling members 24 along the respective arcuate channels 50 until the coupling members 24 abut the end walls of the arcuate channels 50, thus locking the first part 20 relative to the second part 22.

An electrical connector includes an insulative housing (4), an insulative carrier (1), a spring (3) and a pair of conductive contacts (2). The insulative housing has a base (41) and a periphery wall enclosing therearound and defines a cavity therein. The base has a post (414) formed thereon. The carrier engages with the insulative housing and has a projection (12) formed on an upper surface thereof. The spring couples with the post and abuts the carrier. The conductive contacts are received in the cavity and each includes a contacting portion (21) extending upwardly and engaging with the projection.

An electrical connector (1) includes an insulative housing (10), a number of contacts (20) received in the housing, an inner shell (30) and an outer shell (40) covering the housing. The housing defines a partition (13) extending forwardly. The outer shell defines a pair of concaves (46) and a pair of resilient grounding tabs (411) extending upwardly therefrom for contacting with a metal panel of a personal computer to establish ground connections. The inner shell surrounds the partition with a pair of tangs (33) engaging in the concaves of the outer shell.
