Filed:

Oct 27, 2000

Appl. No.:

09/703988

Inventors:

Jason P. Jacobs - San Francisco CA

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H03K 312

US Classification:

327217, 327219, 327215, 327225, 327218

Abstract:

A multiple input set/reset circuit is described that includes cross-coupled inverters connected between set and reset nodes. The set/reset circuit also includes at least one set input circuit coupled to the set node configured to receive a set signal and to drive the set node to a first logic state in response to the set signal asserted, and at least one reset input circuit coupled to the reset node configured to receive a reset signal and drive the reset node to the first logic state in response to the reset signal asserted. Incorporated into the set/reset circuit are a first switching circuit to change the logic state of one of the nodes to a second logic state when the other node changes the logic state to the first logic state, and a second switching circuit to disable the first switching circuit after the first and second nodes have completed a logical state change in response to a set or reset signal asserted.

International Classification:

A61C 500

US Classification:

433215

Abstract:

An improved dental procedure contacts a tooth with a fluoride carrier to produce a fluoride containing layer on the tooth. The tooth is then irradiated with UV radiation in the wavelength range of 100-400 nm. The fluoride carrier is at least 70% transparent to UV radiation, and the radiation is provided with sufficiently low energy to avoid inflicting pain on the patient.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

A61B 1736

US Classification:

606 12

Abstract:

An improved dental procedure and apparatus where ultraviolet radiation pulses are used to etch selectively both hard tissue and soft tissue in dental procedures. There exists distinct ablation thresholds for hard and soft tissue which are dependent on the material being ablated for a given wavelength of the ultraviolet radiation. Sufficient differences in ablation threshold exist for enamel, dentin, and carious material, thereby allowing dentists to perform both hard tissue and soft tissue procedures without excess damage of healthy enamel, dentin or other pulp structures.

US Classification:

606 10

Abstract:

An improved dental procedure and apparatus where ultraviolet radiation pulses are used to etch selectively both hard tissue and soft tissue in dental procedures. There exists distinct ablation thresholds for hard and soft tissue which are dependent on the material being abated for a given wavelength of the ultraviolet radiation. Sufficient differences in ablation threshold exist for enamel, dentin, and carious material, thereby allowing dentists to perform both hard tissue and soft tissue procedures without excess damage to healthy enamel, dentin or other pulp structures.
