摘要:
A needle threading device includes a rectangular block housing including a chamber at a lower end thereof which opens through a side wall. A needle receiving bore extends through a top wall of the housing for receiving a needle; and a V-shaped recess at the lower end of the needle receiving bore aligns the needle with a predetermined orientation. A thread receiving notch in the housing adjacent to the needle receiving bore receives a thread to be inserted through an eye of the needle when the needle is in the needle receiving bore. An actuator is slidably positioned in the chamber for pushing the thread in the thread receiving notch through the eye of the needle in the needle receiving bore. The actuator includes a block slidable with the chamber and a mandrel secured to an upper end of the block and extendible through a tunnel which connects the chamber with the lower end of the thread receiving notch, through another tunnel which connects the lower end of the thread receiving notch with the lower end of the needle receiving bore so as to push the thread from the thread receiving notch through the eye of the needle in the needle receiving bore and then through a tunnel which connects the lower end of the needle receiving bore to the outside of the device whereby a person can grasp the thread so as to pull the thread through the eye of the needle to a desired length.
摘要:
A hardware independent and graphically extensible tester state browsing technique for observing and modifying operating state of test equipment includes accessing a descriptor file describing an architecture of the test equipment, invoking a set of plugins associated with one or more subsystems of the test equipment, and displaying a map with a set of drill-down mechanisms each associated with different ones of the subsystems of the test equipment which invoke the respective plugin associated with its corresponding respective subsystem.
