Patent number: 6144370Abstract: A track ball control system which is attachable to a computer system that has a display screen on which a cursor is positionable, including at least one track ball regulator for providing physical control of the position of the track ball in response to signals from the control system. These signals depend on the location of the cursor on the display screen and cause the track ball to change in movement. This change in movement may be a vertical change, and/or an azimuthal change. The operator does not control this change in movement except indirectly by knowingly or unknowingly positioning the cursor in a position which causes the signals to be sent to the track ball.Type: GrantFiled: April 1, 1997Date of Patent: November 7, 2000Assignee: The University of North Carolina at CharlotteInventors: Nadeem N. Eleyan, Stephen M. Bobbio

Patent number: 6013381Abstract: A method for pretreating a solder surface for fluxless soldering is disclosed. The method uses a noble fluorine gas to remove surface oxides from solder surfaces, without the use of external stimulation. A noble fluorine gas is suffused across the solder surface to reduce or eliminate or chemically convert the surface oxides. The process can take place at atmospheric pressure and room temperature. A simple belt driven transport may be used to move the parts past a nozzle which emits the vapor in a system similar to a conventional solder reflow machine.Type: GrantFiled: September 15, 1997Date of Patent: January 11, 2000Assignee: MCNCInventors: Stephen M. Bobbio, Glenn A. Rinne

Patent number: 5961031Abstract: A method of forming hydrogen fluoride (HF), to allow fluxless soldering, from a solid source such as potassium hydrogen fluoride (KF.HF) using a specialized apparatus, including a cartridge which is heated in a controlled atmosphere apparatus. The gaseous reaction product, HF, may be extracted from the apparatus either by itself or in a carrier gas (such as argon or nitrogen). The solid reaction product, potassium fluoride (KF), is an inert material which remains in the cartridge. The combination of the cartridge and KF may be safely disposed of as a unit or refilled with KF.HF under controlled conditions.Type: GrantFiled: November 21, 1997Date of Patent: October 5, 1999Assignee: The University of North Carolina at CharlotteInventors: Stephen M.

Patent number: 5698942Abstract: A field emitter flat panel display and associated method of operation provides an electron emission path along which a beam of electrons emitted by a microelectronic field emitter travels such that the electrons impinge upon a light emitting element without passing through a mirror. The light emitting element is spaced apart from the microelectronic field emitter and includes a mirror and a luminescence layer on the mirror. The flat panel display can also include a deflector, such as a deflector electrode, which is spaced apart from both the microelectronic field emitter and the associated light emitting element and which controllably deflects the beam of electrons emitted by the microelectronic field emitter toward the luminescent layer of the associated light emitting element and along a curved electron emission path which is independent of the underlying mirror.Type: GrantFiled: July 22, 1996Date of Patent: December 16, 1997Assignee: University of North CarolinaInventors: Richard F. Greene, Stephen M. Bobbio, Farid M. Tranjan, Kasra Daneshvar, Thomas D. DuBois

Patent number: 5563466Abstract: This invention incorporates micro-machining fabrication techniques to achieve practical electrostatic actuation forces over a length change of the order of 20 to 50 percent. It constitutes an improvement over the prior art by virtue of array designs which yield a more versatile and stronger actuator. One basic design utilizes diamond-shaped attractive elements to transmit transverse forces for longitudinal, two-way actuation. Another basic design features interlocking, longitudinally attractive elements to achieve longitudinal, two-way actuation. Other improvements include means for locking the actuator at an arbitrary displacement as well as means for amplification of either the actuation force or length change.Type: GrantFiled: June 7, 1993Date of Patent: October 8, 1996Inventors: Brian G. Rennex, Stephen M. Bobbio

Patent number: 5499754Abstract: A fluxless soldering sample pretreating system includes a sample chamber having an opening therein and a sample holder. A sample chamber extension extends outwardly from the opening to define a passageway from the sample chamber extension, through the opening, and into the sample chamber. A fluorine-containing gas is supplied into the sample chamber extension. Am energy source such as a microwave oven surrounds the sample chamber extension. The microwave oven produces microwave energy in the sample chamber extension to form a plasma therein and dissociate the fluorine-containing gas into atomic fluorine. A perforated aluminum plate extends transversely across the passageway and blocks the plasma from traversing the passageway from the sample chamber extension into the sample chamber, while allowing the atomic fluorine to traverse the passageway from the sample chamber extension into the sample holder.Type: GrantFiled: November 15, 1994Date of Patent: March 19, 1996Assignee: MCNCInventors: Stephen M. Bobbio, Nicholas G. Koopman, Sundeep Nangalia

Patent number: 5479061Abstract: An electrically and mechanically robust microelectromechanical transducer is formed of a pleated dielectric sheet having patterned electrical conductors on the opposing faces thereof. The pleats define a plurality of spaced apart walls, with each wall including an electrically conductive portion at one side thereof. Positive and negative voltages, applied to opposite faces of the pleated sheet, cause the walls to move towards one another by electrostatic attraction. The walls can also move away from one another by electrostatic repulsion upon application of appropriate voltages. The microelectromechanical transducer may be fabricated by fabricating a sheet with integral pleats or by forming a "self-pleating" flat sheet which forms pleats after conductor fabrication thereon.Type: GrantFiled: December 31, 1992Date of Patent: December 26, 1995Assignees: University of North Carolina, MCNCInventors: Stephen M.
