Appl. No.:

13/545060

Inventors:

Christopher P. STEINMAN - Sandy UT, US
Jeffrey S. LOUIS - Akron OH, US
Rick W. WALKER - Stow OH, US
Evan D. SHAPIRO - Chicago IL, US
Aaron R. FERBER - Chicago IL, US
Rodney H. MONSON - Waukegan IL, US

Assignee:

LIFELINE SCIENTIFIC, INC. - Itasca IL

International Classification:

A01N 1/02

US Classification:

435 12, 4352841

Abstract:

An apparatus for separating gas bubbles that may be entrained in perfusate flow prevents such bubbles from continuing downstream and entering an organ or tissue. The apparatus may include a chamber having a top wall, a bottom wall and side walls. The chamber may include an inlet configured to allow at least one of gas and liquid to enter the chamber, an air opening configured to allow at least gas to exit the chamber and a first liquid opening configured to allow at least liquid to exit the chamber. The apparatus may function as an accumulator that reduces or eliminates pulsatility of the liquid flow and pressure. The apparatus may include a minimum volume of gas, initially or through the accumulation of gas, such that flow and pressure fluctuations in the liquid are dampened or eliminated. The apparatus may include a sampling port in a wall of the chamber.

International Classification:

A01N 1/02

US Classification:

435 12, 4352841

Abstract:

An apparatus for perfusing an organ or tissue includes a perfusion circuit configured to perfuse the organ or tissue; at least one shock and/or tilt detector such as an accelerometer; and a controller. The controller may be configured to control perfusion based upon a signal received from the accelerometer, which may include stopping and/or starting the perfusion based upon the signal. The controller may also or alternatively sense and/or record shocks experienced by the apparatus.

Appl. No.:

7/444737

Inventors:

Kurt Zwirner - Melrose MA

International Classification:

G01B 1102
F21V 704

US Classification:

356384

Abstract:

A backlighting system is comprised of a light source, a sensing portion and an imaging portion. The light source may be a linear backlight that has few hot spots and provides uniform lighting oriented primarily in a single dimension. Alternatively it may be an area backlight that provides backlighting in a uniform manner across two-dimensions. Furthermore, a line light source may be provided that provides a relatively large line source of light oriented almost exclusively in a single dimension. The imaging portion of the machine vision system preferably includes an element for homogenizing the received image onto the imaging array. The homogenization element may adopt either a dispersing approach or a condensing approach.
