A method for writing and reading in-band information to and from a single storage element, comprising the steps of receiving the in-band information, storing data in either a port information register when in a first state or a memory element when in a second state and storing subsequent data in the memory element. The button is held in its rest position by a restoring force and can be pushed in counter to the action of this restoring force. The main components of the device are paddle and at least one crossbar assembly. A compensated control signal is produced from the desired valve flow coefficient and the characterization data, to counter act effects that changes in differential pressure have on flow of fluid. The one-part epoxy resin composition of the present invention comprises a bisphenol A type andor F type epoxy resin which is in liquid form at room temperature, methylnadic anhydride as a cycloaliphatic anhydride which is in liquid form at room temperature, and a nitrogen-containing latent hardening accelerator.
