Abstract: An electrochemical sensor structure (30) includes a housing (32) having an inner surface defining a housing cavity (42). The sensor (30) also has an inner body (34) having an outer surface (51). The outer surface (51) of the inner body (34) and the inner surface of the housing (32) have engaging portions which directly engage one another to form a channel therebetween. The channel defines an ionic junction in the sensor (30).

Abstract: A measuring probe (12) measures a parameter with a sensor (20). The sensor (20) provides a sensor output signal related to a measured value. An amplifier (28) section receives the sensor output signal and provides an amplifier output signal. An integrator (34) has an input and an integrator output related to an integration of the input. Switching circuitry (32) receives the amplifier output signal and a reference signal and has an output connected to the input of the integrator (34). Controller circuitry (26) coupled to the switching circuitry (32) connects the amplifier output to the integrator input during a sampling time, and the reference signal to the integrator input during a conversion time. The conversion time is related to the sensor output signal and is measured to obtain a digital representation of the sensor output.

Abstract: A micromachined mass spectrometer (10) includes an ionizer (30), a separation region (32) and a detector (34). The ionizer (30) is formed from an upper electrode (36), a center electrode (38) and a lower electrode (40). Ionization (30) of a sample gas takes place around an edge (48) of the center electrode (38). Accelerating electrodes (54, 56) extract ionized particles from the ionizer (30). Ionized particles are accelerated through the separation region (32). A magnetic field is applied in a direction perpendicular to travel of the ionized particles through the separation region (32) causing the trajectory of the ionized particles to bend. The mass spectrometer (10) is formed using micromachined techniques and is carried on a single substrate (24).

Abstract: A valve controlling fluid flow includes a brittle layer (12) of material having a port opening (30, 32) therein and a valve seat (24A-24F) disposed about a perimeter of the port opening (30, 32). The valve seat (24A-24F) is selectively covered to control fluid flow through the port opening (30, 32). A second layer of material (20) is spaced apart from the brittle layer (12) and has a surface facing the valve seat (24A-24F). A flexible sheet of material (18) sandwiched between the brittle layer of material (12) and the second layer of material (20) includes a diaphragm (22A-22F) actuated by a control force to selectively cover the valve seat (24A-24F) to thereby control fluid flow through the port opening (30, 32). The flexible sheet of material (18) includes a moldable material (64) a portion of which conforms to a contour of the valve seat (24A-24F). The moldable material (64) is preferably joined to a flexible organic material (66).
