Abstract: An orthopaedic surgical instrument includes a patella trial and drill guide that may be used to both perform a surgical trial of the patellofemoral joint and guide the surgeon in drilling a number of anchor holes in the patella of the patient.

Abstract: A system and method for modifying monoatomic oxygen levels in an initial fluid, for applications. The system and method produces both positive and negative oxygen modified fluid that retains oxygen levels for long durations as measured by oxygen reduction potential (ORP). An incoming fluid is split between a positive chamber defined by a cathode and a porous divider and a negative chamber defined by the porous divider and an anode. The relative charge over the porous divider produces fluid with elevated ORP from the positive chamber and fluid with lowered ORP from the negative chamber. A method of killing bacteria includes contacting the bacteria with negative ORP fluid produced in the system and method to the bacteria.

Abstract: This invention is directed to myocardial imaging of human patients having a history of asthma or bronchospasm. In particular, the present invention uses binodenoson as a pharmacological stressor in conjunction with any one of several noninvasive and invasive diagnostic procedures available. For example, intravenous administration may be used in conjunction with a radiopharmaceutical agent and myocardial perfusion imaging to assess the severity of myocardial ischemia.

Abstract: Confectionary image design system including a graphical user interface through which a user defines a pattern of confectionary pieces to be arranged on a substrate. A computer processor controls the graphical user interface through which the user defines the pattern, and provides instructions for arranging the confectionary pieces in the defined pattern. A container retains the confectionary pieces used to form the defined pattern. A robot receives from the computer processor the instructions for arranging the confectionary pieces, retrieves the confectionary pieces stored in the container, and arranges the pieces on the substrate in the pattern defined by the user.

Abstract: The neutral override circuit of this invention includes a variable displacement pump controlled by a servo fluidly connected to a displacement control that is biased to a neutral position. A charge pump is connected to the pump and the displacement control. A solenoid-operated neutral override brake control valve is connected to the charge circuit upstream of the displacement control valve and is normally biased to an open position. However, the solenoid urges the valve to a closed position in a response to a signal indicating that the brake has been released. In the open position, the valve dumps charge flow to the pump case until the supply pressure to the displacement control is inadequate to overcome the centering bias of the displacement control. The characteristics of the brake control valve can be set so that some minimum charge pressure and lubricating flow are still provided to the rotating elements of the pump.
