Abstract: A system for driving one or more electrical currents includes a current driver operable to cause current to flow to the one or more driven electrical elements, a sensor module for sensing a current at the input of the current driver, a compensation module for compensating an input control signal based on the sensed current at the input of the current driver and an optocoupling module having a grounded side connected to an earth ground and a floating side connected to a floating ground. The grounded side receives the compensated control signal and the floating side outputs a floating control signal corresponding to the compensated control signal. An amplification module connected to the floating ground is operable for amplifying the floating control signal outputted from the optocoupling module. The amplified floating control signal further controls the current driver to cause the flow of current to the driven electrical elements.

Abstract: A necklace having a chain and a jewelry element has attaching members at each end of the chain and two pins extending from a rear surface of the jewelry element, with the pins disposed through the attaching members and bent back to the rear surface. A jewelry element having two L-shaped members, with a pin extending from an upright side of each and having an opposite end in close proximity to a base of each L-shaped member is disclosed. A jewelry element may have two pins attached at one end, terminating at the other end in a ball and disposed through attaching members, attached to ends of a chain. A method of making a necklace from a jewelry element having two pins extending from a rear surface thereof and a chain having attaching members at each end includes placing each attaching member over a pin and bending each pin back to the rear surface or heating each pin to form a ball at the end thereof.
