A programming device comprising a group of program generation tools to generate programs for a plurality of devices that form part of a control system. The trip unit includes a sensor structured to sense current flowing through the contacts, a processor structured to output a trip signal responsive to the sensed current, and a trip actuator. The enhancement can be by either adding a storage capacity to the finFET or altering a portion of the finFET after formation of a fin body of the finFET. The first and second housings include respective contact surfaces, which are pressed against each other in the open state, thereby maintaining a posture of the second housing relative to the first housing. Upon receipt of the request, the software supplier verifies entitlement of the requester to the key including licensing, payment, and configuration concerns. Thus, the optical module integrated package not only have the chip and the electronic component integrated therein to reduce the packaging cost and to improve the yield but also provide a light filtering, focusing or diffusing effect to enhance optical recognition accuracy.
