Publication number: 20210402033Abstract: Aspects of the present disclosure relate to a reading apparatus that a well formed from a portion of a housing. The well dimensioned to receive at least a portion of a sterilization indicator having spores. The reading apparatus can also have a heating element thermally coupled to a portion of the well and an excitation source to excite the substance in the sterilization indicator. The reading apparatus can have a sterilization indicator activation circuit for detecting activation of the sterilization indicator. The excitation source is positioned such that light from the excitation source is directed into the well. A color sensor can be positioned adjacent the well to receive reflected light from the sterilization indicator.Type: ApplicationFiled: March 13, 2020Publication date: December 30, 2021Inventors: Peter D. Ludowise, Anthony J. Jennen, Barry W. Robole, Leroy J. Longworth

Publication number: 20190117810Abstract: Process monitoring systems include a reader having a read sensor, an optional reference sensor, and a light source. The reader optionally includes an optical block defining an interior volume and an aperture aligned with the read sensor to allow diffuse light to be received by the read sensor. One or more percent reflectance values may be calculated in response to a dark measurement, a correction function, and normalization. The one or more percent reflectance values may be compared to a threshold to determine whether a disinfection cycle was effective. The reader may indicate the determination to a user and provide the determination to a tracking system for diagnostics, inventory management, or compliance monitoring.Type: ApplicationFiled: April 19, 2017Publication date: April 25, 2019Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: PETER D. LUDOWISE, ANTHONY J. JENNEN, BARRY W. ROBOLE, PHILIP G. DION, LEROY J. LONGWORTH, JAY R. GOETZ

Patent number: 9428786Abstract: A biological sterilization indicator (BI) system and method. The system can include a BI and a reading apparatus comprising a well. The BI can include a housing, which can include a first portion, and a second portion movable between a first “unactivated” position and a second “activated” position. The BI can further include a frangible container containing a liquid and dimensioned to be positioned in the housing. The reading apparatus can be configured to detect activation of the biological sterilization indicator, for example, by detecting that the second portion is in the second position, and/or by detecting that the liquid from the frangible container is present in a specific chamber of the biological sterilization indicator. The method can include positioning the BI in the well of the reading apparatus and detecting activation, for example, by detecting one or more of the above conditions.Type: GrantFiled: August 18, 2015Date of Patent: August 30, 2016Inventors: Jeffrey C. Pederson, Sailaja Chandrapati, Bryan S. Behun, Barry W. Robole, Leroy J. Longworth

Patent number: 9410180Abstract: A biological sterilization indicator (BI) system and method. The system can include a BI and a reading apparatus comprising a well. The BI can include a housing, which can include a first portion, and a second portion movable between a first “unactivated” position and a second “activated” position. The reading apparatus can detect at least one of (i) when the well is empty; (ii) when the biological sterilization indicator is positioned in the well with the second portion of the housing in the first position, and (iii) when the biological sterilization indicator is positioned in the well with the second portion of the housing in the second position. The method can include detecting at least one of the above conditions, which can be used to detect an activation status of the biological sterilization indicator.Type: GrantFiled: October 28, 2011Date of Patent: August 9, 2016Inventors: Jeffrey C. Pederson, Sailaja Chandrapati, Bryan S. Behun, Barry W. Robole, Leroy J. Longworth, Kaileen Chen

Patent number: 6839833Abstract: A programmable pipeline depth controller is provided to control the number of instructions that begins execution within an instruction pipeline of an instruction processor within a predetermined period of time. The pipeline depth controller of the present invention includes a logic sequencer responsive to a programmable count value. Upon being enabled, the logic sequencer generates a pipeline control signal to selectively delay the entry of some instructions into the instruction pipeline so that the number of instructions that begins execution within the instruction pipeline during the predetermined period of time following the enabling of the logic sequencer is equal to the count value.Type: GrantFiled: October 15, 1999Date of Patent: January 4, 2005Assignee: Unisys CorporationInventors: Thomas D. Hartnett, John S. Kuslak, Leroy J. Longworth
