An exemplary latching mechanism (20) includes a base (22), a detachable portion (24), a rotatable wheel (25), and a resilient member (28). The base has two resilient hooks (224). The detachable portion has two clasping portion (244) for engaging with the resilient hooks. The rotatable wheel has a plurality of hook openers (256) and is rotatable between two states forced by the detachable portion. The resilient member is disposed between the base and detachable portion for providing elastic force. The at least one clasping portion of the detachable portion engages with the at least one resilient hook of the base and the rotatable wheel is at a second state. The rotatable wheel is rotated to a first state and the at least one resilient hook are pushed to deform by at least one of the hook openers of the rotatable wheel.

A new method is provided for evaluating the alignment of inner layers of interconnect layers. A test pattern is inserted within and as part of the process of creating a saw singulated plastic ball grid array substrate. The test pattern comprises a test point of reference for each inner layer of the substrate and multiple measurement points relating to the point of reference whereby each of these multiple measurement points is indicative of an amount of clearance or misalignment with respect to that inner-layer. By measuring electrical continuity or lack thereof between the point of reference and the respective multiple measurement points relating to the point of reference and by identifying which of the multiple points is shorted to the point of reference, the mis-alignment of the inner layers of the saw singulated plastic ball grid array substrate can be determined.

The present invention relates to a data transmission method in a radio communication system, comprising the steps of selecting a first reference transmission antenna of a first base station and a second reference transmission antenna of a second base station from among a plurality of base stations, transmitting a first transmission data stream via the first reference transmission antenna, transmitting a second transmission data stream via the second reference transmission antenna to a terminal, time-delaying the first transmission data stream and retransmitting the delayed first transmission data stream to the terminal via a transmission antenna of a first transmission group, and time-delaying the second transmission data stream and retransmitting the delayed second transmission data stream to the terminal via a transmission antenna of a second transmission group. Thus, co-channel interferences can be minimized, and the efficiency in using an antenna and the receiving performance thereof in a radio communication system adopting a multi-antenna technique and a multi-base station system can be improved at the same time.

An exemplary mechanical joint system includes a joint, an arm, a plurality of teeth, an engaging member, and at least one latching member. The joint defines a pivot hole and a joint receiving hole communicating with the pivot hole. The arm is rotatable relative to the joint and includes a pivot portion and a pivot hole defined in the pivot portion. The pivot portion is received in the joint receiving hole. The engaging member includes a pivot shaft and a fixing member fixed relative to the pivot shaft. The plurality of teeth extends from an outer surface of the shaft portion of the pivot shaft. The latching member is mounted in the pivot hole of the pivot portion of the arm for engaging with the teeth.

An exemplary joint mechanism (100) includes a pivot shaft (10), a joint (20), a rotary arm (30), and two bearings (50). The pivot shaft (10) is non-rotatable relative to the joint (20). The joint (20) is received in the rotary arm (30). The rotary arm (30) is rotatable relative to the joint (20). The two bearings (50) are fixed to an inner surface of the rotary arm (30). Each bearing (50) includes a concave inner surface, and the concave inner surface is engaged with a curved outer surface of the joint (20).

An exemplary latching mechanism (20) includes a base (22) having two resilient claps (224), a detachable portion (24) having two resilient clasps (244) for engaging with the hooking portions of the base, and an unlatching element (25). The unlatching element defines two engaging slots (258) and is disposed between the base and the detachable portion. The resilient clasps of the detachable portion engage with the hooking portions of the base when the detachable portion is pressed to be latched to the base. The resilient clasps engage in the engaging slots of the unlatching element when the detachable portion is pressed to be detached from the base. Then the detachable portion and the unlatching element together move away from the base. The engagement of the detachable portion and unlatching element makes the at least one resilient clasp deforms and thus disengages from the at least one hooking portion of the base.

An exemplary rotatable joint (100) used for a mechanical device includes a socket (10), a rotatable arm (20), a supporting shaft (13), a fastening member (15), an adjusting member (16), and a resilient module (18). A pivot hole (212) is defined in the rotatable arm. The supporting shaft includes a first shaft portion (130) and a second shaft portion (132). A threaded hole (131) is defined in the first shaft portion and the first shaft portion extends through the pivot hole. The second shaft portion is fixed to the socket. The fastening member includes a threaded portion (152) for engaging in the threaded hole of the supporting shaft. The adjusting member is disposed at the threaded portion of the fastening member. The resilient module is disposed between the rotatable arm and the adjusting member for providing an axial resilient force. The axial resilient force is fine tuned by moving the adjusting member.
