US 8,699,983 B2 · Six port linear network single wire multi switch transceiver

Abstract

A fluid sensor comprises a sensor housing (12), a sensor package (14), an actuator (16) and a switch (18). The sensor package (14) is disposed within the sensor housing (12) and includes first and second screens and at least one sensing membrane. The sensing membrane is disposed between the first and second screens (36) and is adapted to expand when exposed to a predetermined quantity of a first predetermined fluid. The actuator (16) is disposed proximate the sensor package (14) within the sensor housing (12) and moveable between a first position and a second position through an intermediate position. The switch (18) is disposed proximate the actuator (16) and is operable between closed and open positions. When the actuator (16) is in the second position at least a portion of the actuator (16) depresses the switch (18) to control an-electrical, circuit connected therewith.

Dependent claims

An apparatus comprising:

a first DC voltage block coupled between a source of a first RF signal and a first transmission line, said first RF signal having a first frequency;
a second DC voltage block coupled between a source of a DC potential and a source of reference potential;
and
a first band reject filter for rejecting said first frequency, coupled between said source of the DC potential and the first transmission line;
a third DC voltage block coupled between a source of a second RF signal and a second transmission line, said second RF signal having a second frequency;
a second band reject filter for rejecting said second frequency, coupled between said first transmission line and the second transmission line;
and
a low pass filter coupled between the first transmission line and the source of reference potential.
