US Patent:

20130008237, Jan 10, 2013

Filed:

Jan 10, 2011

Appl. No.:

13/520605

Inventors:

James E. Usowicz - Webster MA, US
Tony A. Lin - Ashland MA, US
Joshua A. Burnett - Taunton MA, US
Marc Lemelin - Douglas MA, US

International Classification:

G01N 30/00

US Classification:

73 6152

Abstract:

Described are techniques for force sensing. A computing device is configured to have a desired force setting. A first vertical position of a needle is determined using the computer device. A control signal is sent from the computing device to a positioning device. In response to the control signal, the needle is positioned at the first vertical position. When in the first vertical position, surfaces of a tip of the needle are in contact with surfaces of an opening of a sealing member and positioning the needle causes application of a force at surfaces of the opening in contact with surfaces of the tip of the needle. In response to application of the force, a spring is compressed a distance that is proportional to the force. The force is measured using a force sensor.

International Classification:

G01N 1/00

US Classification:

7386485

Abstract:

Described are techniques for use with an injection port. The injection port includes a needle support structure configured to accommodate a needle containing a sample aspirated therein. The injection port includes a needle seal having a first surface thereof in contact with a second surface of a tip of the needle. A seal is formed when the first surface contacts the second surface and a sufficient force is applied to the needle.

International Classification:

G01N 30/30
H05B 3/42
G01N 30/54

Abstract:

To heat a flowing liquid, an apparatus includes a heater block assembly having a heater block made of thermally conductive material. The heater block assembly has a tube inlet, a tube outlet, and a tube path between the tube inlet and tube outlet. Tubing extends through the tube path from the tube inlet to the tube outlet. The tubing is in thermal communication with the heater block. A heater cartridge, in thermal communication with the heater block, is configured to provide heat to the heater block for transfer to liquid flowing through the tubing between the tube inlet and the tube outlet of the heater block assembly. Circuitry is in electrical communication with the heater cartridge to control a temperature of the heater block by controlling operation of the heater cartridge.
