Patent number: 8834792Abstract: A system and method for processing sample processing devices. The system can include a base plate adapted to rotate about a rotation axis. The system can further include a cover including a first projection, and a housing. A portion of the housing can be movable with respect to the base plate between an open position and a closed position, and can include a second projection. The first projection and the second projection can be adapted to be coupled together when the portion is in the open position and decoupled when the portion is in the closed position. The method can include coupling the cover to the portion of the housing, moving the portion of the housing from the open position to the closed position, and rotating the base plate about the rotation axis.Type: GrantFiled: November 13, 2009Date of Patent: September 16, 2014Assignee: 3M Innovative Properties CompanyInventors: Barry W.

Patent number: 8700118Abstract: A biomedical sensor system. The system can include a sensor adapted to create a signal based on a physiological characteristic from a subject, and a hub adapted to receive the signal from the sensor. The signal can include at least one of an electromagnetic signal, an electrical signal, an acoustic signal, a mechanical signal, a thermal signal, and a chemical signal. The system can further include a connector adapted to couple the sensor and the hub, the connector having a variable length, such that the sensor and the hub can be positioned a variable distance apart by changing the length of the connector. The connector can be adapted to provide a pathway between the sensor and the hub for the signal. A method of applying a biomedical sensor system to a subject can include changing the length of the variable-length connector to provide an appropriate distance between the sensor and the hub, and coupling the sensor to the subject.Type: GrantFiled: April 29, 2009Date of Patent: April 15, 2014Assignee: 3M Innovative Properties CompanyInventors: Craig D.

Patent number: 8128893Abstract: Processing devices that include one or more process arrays with thermal transfer structures that can be used alone or in conjunction with gravity/rotation to transport fluids within a microfluidic system. The thermal transport function can be accomplished by changing the temperature of one or more chambers to create a vacuum to draw fluids in selected directions within the process array. The methods and apparatus of the present invention may provide the ability to move fluids in a direction that is against the direction of gravity or any centrifugal forces generated by rotating a processing device using the thermal transfer structures. In other words, fluids may be moved against the direction of gravity or towards the axis of rotation using the thermally-activated vacuum.Type: GrantFiled: December 21, 2007Date of Patent: March 6, 2012Assignee: 3M Innovative Properties CompanyInventors: William Bedingham, Christopher R.
