    摘要: An interface output stage includes a pull-up circuit and a pull-down circuit connected to a positive power supply signal line having a first voltage, an output signal line having an output voltage and a negative power supply signal line having a second voltage. The pull-up circuit includes a single output transistor and a body snatcher circuit, both interconnected between the positive power supply signal line and the output signal line. The body snatcher circuit ties the bodies of the output transistor and the transistors forming the body snatcher circuit to either the first voltage or the output voltage. The pull-down circuit is designed generally similar to the pull-up circuit to tie bodies of its transistors to either the output voltage or the second voltage.

    摘要: An exercise equipment has a structure that can be easily collapsed for storage, and that provides improved utility due to its multiple functional capabilities and configurations thereby enabling a comprehensive set of strength exercises. The exercise equipment includes a rigid base structure that can be folded into compact form when not in use and can be configured for accessories that attach to the base structure. The exercise equipment with attached accessories combines heretofore separate pieces of equipment into one that covers a fraction of the floor space of all such separate pieces of equipment. This provides exercise equipment that is more flexible, more functional, and has a smaller footprint, all of which can be folded up for compact storage.

    摘要: A digital input circuit includes a series connection of a current limiter and a switch having a switch control input coupled between a signal input and ground, and a logic level shifter coupled to the signal input and having a switch control output coupled to the switch control input and a signal output, where a maximum amplitude at the signal input is greater than a maximum amplitude at the signal output. A digital input method includes coupling an input signal to ground with a current limiter by closing an electronic switch, providing an output signal responsive to the input signal, where a maximum amplitude of the input signal is greater than a maximum amplitude of the output signal, by latching the output signal while the input signal is above a threshold voltage and opening the electronic switch after the output signal is latched.
