Patent number: 8519361Abstract: A system for sanitizing an enclosed structure has first and second sensors, a germicidal ultraviolet light source, a motor, and a controller. The first sensor detects humans within the enclosed structure. The second sensor detects the position of at least one door to the structure. The motor selectively moves the light source from an inactive position to an active position. The controller receives inputs from the first and second sensors and transmits outputs to the light source and the motor. When the controller receives signals that no humans or animals are present in the enclosed structure and that the door is in a closed position, the controller transmits a signal to the motor to move the light source from the inactive to the active position. If humans are detected in the structure or if the door is detected open, then the controller deactivates or repositions the light source.Type: GrantFiled: January 16, 2012Date of Patent: August 27, 2013Assignee: Elevated Health Systems, LLCInventor: David Leben

Patent number: 8501461Abstract: An automated analyzer for performing multiple diagnostic assays simultaneously includes multiple stations in which discrete aspects of the assay are performed on fluid samples contained in sample vessels. The analyzer includes stations for automatically preparing a sample, incubating the sample, preforming an analyte isolation procedure, ascertaining the presence of a target analyte, and analyzing the amount of a target analyte. An automated receptacle transporting system moves the sample vessels from one station to the next. A method for performing an automated diagnostic assay includes an automated process for isolating and amplifying a target analyte, and, in one embodiment, a method for real-time monitoring of the amplification process.Type: GrantFiled: December 3, 2009Date of Patent: August 6, 2013Assignee: Gen-Probe IncorporatedInventors: Byron J.
