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.

Patent number: 7300405Abstract: Techniques are described for analyzing auscultatory sounds to aid a medical professional in diagnosing physiological conditions of a patient. A data analysis system, for example, applies singular value decomposition to auscultatory sounds associated known physiological conditions to define a set of one or more disease regions within a multidimensional space. A diagnostic device, such as an electronic stethoscope or personal digital assistant, applies configuration data from the data analysis system to generate a set of one or more vectors within the multidimensional space representative of auscultatory sounds associated with a patient. The diagnostic device outputs a diagnostic message associated with a physiological condition of the patient based on the orientation of the vectors relative to the disease regions within the multidimensional space.Type: GrantFiled: February 18, 2004Date of Patent: November 27, 2007Assignees: 3M Innovative Properties Company, Regents of the University of MinnesotaInventors: Marie A.

Patent number: 5425701Abstract: An orthopedic brace to facilitate healing of injuries to the foot, ankle or portions of the leg above the ankle includes a boot having a lower edge section releasably connected to a sole. The width of the boot, as well as the distance between a pair of upright struts located along opposite sides of the boot, may be varied to complementally match the width of the patient's foot. The struts and a section of fastening straps are located between layers of foam pads of the boot to reduce the likelihood that the straps or struts will become ensnarled with other items. The sole has a mirror image configuration on either side of its longitudinal axis, and left and right insoles are provided so that a single boot may be used with either the left or right foot of the patient.Type: GrantFiled: January 21, 1994Date of Patent: June 20, 1995Assignee: Minnesota Mining and Manufacturing CompanyInventors: Craig D.

Patent number: 5105987Abstract: An applicator for dispensing hot melt adhesives has a receptacle for storing solid blocks of adhesive, along with a feeding mechanism having a movable arm for advancing a single block of adhesive toward a melting chamber. A coil spring element is connected to the arm and unwraps as the arm is advanced in order to retain any remaining blocks of adhesive in the receptacle. At the end of a dispensing operation, the spring exerts just enough force on the arm in a direction away from the melting chamber to relieve pressure against the advanced block, so that the tendency for unwanted molten material to drip from the applicator nozzle is reduced.Type: GrantFiled: November 14, 1990Date of Patent: April 21, 1992Assignee: Minnesota Mining and Manufacturing CompanyInventors: Gerald W. Quinn, Craig D. Oster

Patent number: 4951846Abstract: A hot melt applicator has a feeding mechanism for advancing a block of solid material toward a melting chamber, and the feeding mechanism includes a retraction device for shifting the block a slight distance in a rearward direction to a retracted position subsequent to the dispensing operation. The feeding mechanism has a release device for enabling the block to float freely after moving to the retracted position in order to provide additional room for molten material in the melting chamber upon thermal expansion of the material.Type: GrantFiled: February 2, 1989Date of Patent: August 28, 1990Assignee: Minnesota Mining and Manufacturing CompanyInventors: Craig D. Oster, Gerald W. Quinn, Rodney J. Wilson

Patent number: 4948944Abstract: A heater assembly for a hot melt applicator includes a heating block having a melting chamber and two compartments receiving a pair of elongated heating elements along opposite sides of the chamber. The heating elements have respective longitudinal axes that lie in a common plane which extends toward an outlet of the melting chamber at an angle relative to a central axis of the melting chamber. In preferred forms, the longitudinal axes of the heating elements converge toward each other as the outlet of the melting chamber is approached.Type: GrantFiled: December 19, 1988Date of Patent: August 14, 1990Assignee: Minnesota Mining and Manufacturing CompanyInventor: Craig D.
