US Patent:

20010045036, Nov 29, 2001

Filed:

Feb 7, 2001

Appl. No.:

09/779042

Inventors:

John Maxwell - Garden Grove CA, US
Thomas Maxwell - Garden Grove CA, US

International Classification:

G09F021/04

US Classification:

040/593000

Abstract:

A product is disclosed to assist a vehicle owner and user in properly keeping track of the amount of miles driven in a particular vehicle. The goal of the product is to ensure that regular oil changes will occur approximately every 3,000 miles, which is the usual recommended interval that oil changes occur for most vehicles. The product is a multipage notepad which is preferably one inch tall by one and one-half inches wide, and which can be fastened to an automobile dashboard by means of a mounted Velcro tab, with an accompanying Velcro tab mounted onto the dashboard. The product is designed to provide a user with the ability to perform a quick mathematical calculation in order to determine whether it is presently time to perform an oil change.

Appl. No.:

7/229617

Inventors:

John L. Gehrich - Laguna Beach CA
Thomas P. Maxwell - Santa Ana CA
Thomas G. Hacker - Anaheim CA

Assignee:

Minnesota Mining and Manufactoring Company - St. Paul MN

International Classification:

A61B 500

US Classification:

128637

Abstract:

An assembly useful in conjunction with a signal transmission means for the measurement of a compositional parameter of the blood of a patient is disclosed. This assembly comprises a housing adapted and sized to be located outside the body of a patient and having a fluid flow passage therethrough into which blood from the patient is passed from a hollow tube, the fluid flow passage being defined by a wall which is substantially impermeable to blood, the housing being adapted to be removeably secured to a signal transmission system such that the housing is capable of being removed from the signal transmission system without disrupting the fluid flow passage; and a sensing element located in the housing in or near the fluid flow passage for providing a signal directly to the signal transmission system in response to a compositional parameter of blood located in the fluid flow passage.

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

G01N 3350

US Classification:

436 68

Abstract:

Sensing composition precursors and sensing compositions, useful in sensing the concentration of a gas, e. g. , carbon dioxide, in a medium, e. g. , blood, are disclosed. In one embodiment, the sensing composition precursor comprises a dispersed aqueous liquid including a sensing component dissolved therein, a polymer precursor, and a hydrophilic dispersing agent selected from hydroxyalkyl celluloses and mixtures thereof in an amount effective to facilitate maintaining the dispersed aqueous liquid.

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

G01N 2100

US Classification:

422 81

Abstract:

An endless path calibration system comprising a sensor cassette having a flow-through passage and at least one sensor to be calibrated, a chamber coupled to the sensor cassette to define an endless path and a sterile calibration liquid in the endless path. A gas injection passage for injecting gas into the sterile calibration liquid and a gas vent leading from the endless path to the exterior of the endless path. A check valve allows gas to escape from the endless path and substantially prevents gas and liquid from entering the endless path through the gas vent.

US Classification:

427 2

Abstract:

A method for making a sensing element, and an assembled sensing element, useful in sensing the concentration of a gas, e. g. , carbon dioxide, in a medium, e. g. blood, are disclosed. In one embodiment, the method comprises placing a quantity of a sensing composition precursor between and in contact with a transparent, gas impermeable solid disc and an opaque, gas permeable film, the sensing composition precursor comprises a sensing component, a polymer precursor and a cross-linking agent; and forming a gas sensing composition from this quantity of sensing composition precursor.

Appl. No.:

7/008937

Inventors:

Thomas P. Maxwell - Santa Ana CA

Assignee:

Minnesota Mining and Manufacturing Co. - St. Paul MN

International Classification:

A61B 500

US Classification:

128637

Abstract:

A parameter of blood is sensed in vivo with a system which includes a catheter and a probe. The catheter has a lumen extending therethrough, a proximal end, a distal end and a distal opening at the distal end. The probe includes one or more sensors at its distal end. A saline solution is introduced into the lumen so that there is an interface adjacent the distal opening of the catheter between the blood and saline solution. The probe is received within the catheter and affixed thereto. The interface is moved back and forth in the lumen to expose the sensors to blood so that they can sense the blood parameters of interest.
