Filed:

Nov 13, 1990

Appl. No.:

7/612179

Inventors:

Bruce Murdock - Beaverton OR

Assignee:

Tektronix, Inc. - Wilsonville OR

International Classification:

G01B 714
G01D 2100
G01H 1102
G01R 33035

US Classification:

32420713

Abstract:

A micromechanical sensor comprises a support, a micromechanical element that is movable relative to the support under the application of a stimulus, and a transducer. The transducer comprises a first component carried by the micromechanical element and movable therewith, and a second component stationary relative to the support. One of the first and second transducer components is a member for establishing a magnetic field and the other of the first and second transducer components is a SQUID positioned in the magnetic field for detecting variation in the magnetic field due to relative movement of the micromechanical element and the support.

Daniel G. Teichmer - Portland OR

Assignee:

Tektronix, Inc. - Beaverton OR

International Classification:

G08C 2100

US Classification:

178 19

Abstract:

A touch panel has panel scanning signals selectively applied to the four sides of a touch sensing surface of the panel so as to establish alternating current voltage gradients in desired directions across the touch sensing surface. When the panel is touched, touch signals result and are utilized by a touch location circuit in determining the location of touch. The impedence touch current resulting from a user's touch may also be determined and used. The touch panel circuit automatically compensates for any variations in touch signals which occur when the touch panel is untouched and automatically nulls the touch signals under such circumstances to enhance the accuracy of touch location determination.

Abstract:

When the panel is touched, touch signals result and are utilized by a touch location circuit in determining the location of touch. The impedence touch current resulting from a user's touch may also be determined and used. The touch panel circuit automatically adjusts the frequency of the applied panel signals to shift this frequency away from fixed frequency interference spectra, such as due to cathode-ray tube flyback signals, in the environment in which the touch panel is used. The touch location thereby minimizes the effects of such spectra on touch location determinations.

Assignee:

Tektronix, Inc. - Beaverton OR

International Classification:

B21D 5300
B23K 916

US Classification:

29157C

Abstract:

An aperture plate for an ink jet head is formed by micro electrical discharge machining one surface of the plate to form a dimple-like recess with a relatively wide flat base. An aperture is then formed through the plate in the region of the dimple, as by micro electrical discharge machining. In one method of the invention, recesses are formed in two plates which are then mounted to the body of an ink jet head. A third plate with a formed third aperture is then mounted to the body such that the first, second and third plates overly one another and the third aperture is aligned with the recesses. Apertures of a smaller cross-section than the third aperture are then formed in the first two plates by drilling through the third aperture. The aperture through the first plate is then enlarged.
