The Federal Circuit recently in In re Cellect, invalidated a series of patents based on obviousness-type double-patenting (ODP), finding that term-adjusted patents (PTA) in the same family are invalid ...

Circuit breakers with extra features increase efficiency, thus saving time and money in the long run. Equipped with a wide range of UL approvals, the customer enjoys the advantage of looking no ...

Effective overload protection in a pluggable package is provided by the new TCP thermal miniature circuit breaker. Designed for use with terminal blocks, the circuit breakers offer an integrated ...

Teaming up with the appropriate test adapters, the 300V/8A WTL 4/2 STB disconnect test terminal block makes it possible to open the busbar in the terminal and for the adapter to make contact with a ...

The circuit in Figure 1 is a high-power analog of the popular TL431 programmable shunt regulator. This two-terminal circuit is convenient when the drain of the P-channel FET is grounded, since it ...

It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...
