Filed:

Mar 12, 2002

Appl. No.:

10/096398

Inventors:

Michael D. Potter - Churchville NY

Assignee:

Rochester Institute of Technology - Rochester NY

International Classification:

H01G 700

US Classification:

361277, 361278, 361279, 3612831, 361291, 361290

Abstract:

A varactor includes a first capacitor plate, a second capacitor plate, at least one fixed charge holder, and a control electrode. The second capacitor plate is spaced from and movable towards and away from the first capacitor plate. At least one fixed charge holder with an imbedded charge is on at least a portion of the second capacitor plate. The control electrode is spaced from the second capacitor plate. Applying a bias to the control electrode moves the second capacitor plate towards or away from the first capacitor plate depending on the polarity of the applied bias.

Rochester Institute of Technology - Rochester NY

International Classification:

G11B 700

US Classification:

428446, 1562731, 156 60, 365151, 310324, 428461, 369126, 257350, 438455

Abstract:

A method for electrostatic bonding includes placing a first region of a first unit at least adjacent to a first region of a second unit. The first region of the first unit has trapped charge. A bond between the first region of the first unit and the first region of the second unit is formed by the electrostatic forces between the trapped charge and induced charge in the first region of the second unit. A system for electrostatic bonding includes a first unit having a first region with trapped charge and a second unit with a first region with induced charge. Electrostatic forces between the trapped charge in the first region of the first unit and the induced charge in the first region of the second unit bond the first and second units together.

International Classification:

G01L 700

US Classification:

73700, 257252, 257248

Abstract:

A pressure transducer system includes a housing with a chamber, a member with a stored electrical charge, and a pair of electrodes that are at least partially in alignment with each other. At least a portion of the chamber is at a reference pressure. The member is connected to the housing and extends across at least a portion of the chamber. Each of the pair of electrodes is connected to the housing and is spaced from and on substantially opposing sides of the member. The member is movable with respect to the pair of electrodes or one of the pair of electrodes is movable with respect to the member in response to a monitored pressure.

Abstract:

A sensing system for a target includes a member with an embedded charge, at least one input electrode, at least one output electrode, at least one common electrode, one or more probes, an input system, and an output monitoring system. The input and output electrodes are spaced from and on substantially opposing sides of the member from the common electrode. At least one of the member and the input and output electrodes is movable with respect to the other. The probes which engage with the target hazardous substance are connected to the at least one of the member and the input and output electrodes which is movable with respect to the other. The input system is coupled between the at least one input electrode and the at least one output electrode and provides an input signal. The output monitoring system is coupled between the at least one output electrode and the at least one common electrode and detects a change in an output signal when the target engages with the movable member or electrode.
