The invention includes a hand tool that may be used for applying a design to a jewelry line. The components of the circuit design can be clustered by combining slices and including slices into configurable logic blocks according to design constraints, while leaving enough white space in the configurable logic blocks for post-placement circuit optimizations. A pusher member is disposed within the lumen for deploying the plug and anchoring element out the distal end of the cartridge. According to the micromachined filter system, the micromachined filter may be formed in one or more polysilicon layers of the micro-device. An insulating filling component is filled in the contact hole of the insulating film so as to be interposed between the drain electrode and the pixel electrode in a pixel in which the source line is short-circuited with the drain electrode. An example real-time clock comprises a first counter to count cycles of a selectively-operable clock, a multiplexer to select from at least an output signal associated with the first counter or a continuously-operating clock, and a second counter to count cycles of an output signal of the multiplexer.
