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.

US Classification:

429 96, 429 99, 29428, 29878, 29593

Abstract:

Battery packs having electrically insulating material between conductive surfaces of electrical components are described herein. In some embodiments, a battery pack includes a battery cell with a first conductive surface, an electrically conductive member with a second conductive surface, and electrically insulating material positioned between the first and second conductive surfaces. The electrically insulating material has at least one passage that enables the first and second conductive surfaces to be electrically connected. For example, the passage in the electrically insulating material may be formed by, during, or as a result of a process in which the first and second conductive surfaces are attached, such as by a welding process that both ablates a portion of the electrically insulating material to form the through passage and that physically joins the first and second conductive surfaces, thereby creating an electrical connection therebetween.

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.

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.
