Patent number: 8908162Abstract: Disclosed is a system for aligning a collimator tube with an alignment ring used to hold a film or sensor aligned with the collimator tube. The disclosed alignment system includes a light source, a light detector, and a reflective surface, where, when the collimator and alignment ring are aligned, light emitted from the light source reflects off the reflective surface and is received by the light detector.Type: GrantFiled: February 24, 2012Date of Patent: December 9, 2014Assignee: IDI Dental, Inc.Inventors: Michael R. Razzano, Raynold Lee Saar

Publication number: 20140161234Abstract: Disclosed is an alignment indication system for an X-ray to align a sensor with X-rays emitted from a collimator that includes a conductive surface and two contacts that abut the conductive surface when an alignment ring holding the sensor is properly aligned with the collimator to activate an indicator such as a light when the sensor is properly aligned.Type: ApplicationFiled: December 4, 2013Publication date: June 12, 2014Inventors: Raynold Lee Saar, Michael R. Razzano

Patent number: 7802438Abstract: The present invention provides an airflow control loop that uses averaged airflow measurements without the problems that are normally encountered with averaging measurements, such as the delay introduced into the airflow control loop. This is accomplished, in the present invention, through a predictive control scheme. The predictive control scheme of the airflow control loop calculates the damper sensitivity, calculates the damper runtime needed to achieve setpoint, and then runs the damper for the determined period of time. In addition to the unique airflow control loop used to maintain the constant airflow into the room, the present invention also implements a digital form of proportional, integral, and derivative (PID) control to maintain the room temperature. The digital form of PID control uses non-linear gains which vary according to how far the measured temperature is from setpoint.Type: GrantFiled: November 17, 2006Date of Patent: September 28, 2010Assignee: Automated Logic CorporationInventors: Gerry Glancy Hull, Steven Treece Tom, Raynold Lee Saar

Patent number: 7669777Abstract: The present invention applies a slope predictive control method to a Variable Temperature Control (VTC) system, measuring the slope of the discharge temperature as a function of flow regulation device position, and using this slope to predict the position of the flow regulation device needed to achieve the desired discharge temperature. The present invention also monitors the response of the VTC over time and utilizes a self-learning algorithm to predict the response time of the system in order to determine when further control adjustments need to be taken.Type: GrantFiled: June 12, 2007Date of Patent: March 2, 2010Assignee: Automated Logic CorporationInventors: Gerry Glancy Hull, Steven Treece Tom, Raynold Lee Saar
