Patent number: 6191847Abstract: A fixed optic sensor system (200) comprising a sensor system (210), and electronic sub-system (205) and a communications means (215). The system can be used for detecting the presence of various sample (236) properties and in that regard has widespread application by leveraging off various miniaturized sensor configurations including surface plasmon resonance (50), fluorescence (80), light transmission (125) and others (150). In one embodiment, the communications means (215) is a wireless transmitter/receiver. In another embodiment, a hand held instrument (358) can be used on-site and communicates with the sensor (350) to receive sample (352) related data and transmit it to a remote processing system (370) for further analysis. In yet another embodiment, a hand held instrument (403) has a plurality of cardiac marker binding ligands (400) deposited on the sensor/sample interface providing a medical diagnosis and point-of-care device (403).Type: GrantFiled: February 8, 1999Date of Patent: February 20, 2001Assignee: Texas Instruments IncorporatedInventors: Jose L. Melendez, Richard A. Carr, Patrick Paul Smith, Dwight U. Bartholomew, John H. Berlien, Jr., Frederick F. Geyer, Paul S. Breedlove

Patent number: 4672599Abstract: An improved method of optically writing and/or reading high density information involves: (1) predeterminedly positioning a flat, uniformly thick, flexible, optical disc with respect to an axis of rotation; (2) rotating the disc on such axis at a high speed and in a predeterminedly spaced relation to a predeterminedly shaped, smooth, featureless reference surface and (3) coupling a central region between the disc and reference surface to an ambient gas source. Related apparatus and disc configurations, including embodiments having flexible disc covers, also are disclosed.Type: GrantFiled: February 16, 1984Date of Patent: June 9, 1987Assignee: Eastman Kodak CompanyInventors: Frederick F. Geyer, Dennis G. Howe

Patent number: 4561086Abstract: An optical write/read unit includes a support, an overlying record layer that is constructed for writing or reading with a predetermined light wavelength(s) and is absorptive to light of other wavelengths and a protective cover means that is selectively transparent to light of at least one of said predetermined wavelength(s). In one embodiment the disc unit is adapted for writing and reading with the same light wavelength and the cover means blocks other light wavelengths. In another embodiment the disc unit is adapted to reading with light of wavelength substantially different than the writing wavelength and the cover means selectively transmits the operative (write and read) wavelengths and selectively blocks a large proportion of other light wavelengths. In another embodiment the cover means is selectively transmissive to the reading wavelength and is displaceable to permit writing light onto the record layer.Type: GrantFiled: May 12, 1983Date of Patent: December 24, 1985Assignee: Eastman Kodak CompanyInventor: Frederick F. Geyer

Patent number: 4536869Abstract: An optical disk assembly includes a flexible disk-shaped support carrying a record layer. The support has an information storage region. An annular retaining ring engages the annular peripheral region of the support. The support, and preferably a cover sheet, are captured between the outer annular reference ring member and an inner annular reference ring member which has been conically deformed to spring toward the outer ring member.Type: GrantFiled: January 17, 1983Date of Patent: August 20, 1985Assignee: Eastman Kodak CompanyInventors: Jasper S. Chandler, Frederick F. Geyer

Patent number: 4475179Abstract: Spot-focus of a write or read beam upon a flexible optical disc, which is rotated with its neutral plane highly stabilized in space, is maintained precisely by moving the write or read beam source (e.g. a laser diode) in response to focus error signals.Type: GrantFiled: June 30, 1982Date of Patent: October 2, 1984Assignee: Eastman Kodak CompanyInventor: Frederick F. Geyer

Patent number: 4462036Abstract: An optical disc assembly includes a flexible disc-shaped support. An annular retaining ring engages the support around its periphery. The support carries a record layer with an information storage region of the record layer located between the retaining ring and a central hub. In use on cooperating optical disc write/read apparatus having disc assembly receiving structure, the central hub positions an annular area of the support, which area is radially inward of the storage region, against a locating surface of the receiving structure with a predetermined abutting force, whereby firm contact is assured between the support and the location surface radially inwardly of the storage region of the record layer. The disc assembly includes a flexible, transparent cover sheet which is coextensive with the support.Type: GrantFiled: October 14, 1982Date of Patent: July 24, 1984Assignee: Eastman Kodak CompanyInventors: Eric M. Leonard, Frederick F. Geyer, George M. Myers

The support carries a record layer with an information storage region of the record layer located between the retaining ring and a central hub. In use on cooperating optical disc write/read apparatus having disc assembly receiving structure, the cental hub positions an annular area of the support, which area is radially inward of the storage region, against a locating surface of the receiving structure with a predetermined abutting force, whereby firm contact is assured between the support and the location surface radially inwardly of the storage region of the record layer. The disc assembly includes a flexible, transparent cover sheet which is coextensive with the support.Type: GrantFiled: October 14, 1982Date of Patent: May 29, 1984Assignee: Eastman Kodak CompanyInventors: Eric M. Leonard, Frederick F. Geyer, George M. Myers
