Patent number: 11703394Abstract: A system includes a measurement instrument including a first connector, a control module, and a display. A temperature probe includes a shaft and a tip. A second connector is coupled to a first end of the shaft. The tip is coupled to a second end of the shaft and measures a change in temperature of a sample. The second connector is received by the first connector when the temperature probe is attached to the measurement instrument. A storage module is housed within the second connector and stores parameters of the temperature probe. The control module receives the parameters, prompts a user to select the sample on the display, and determines a thermal conductivity and a stable time of the sample. When the stable time has elapsed, the control module determines a temperature measurement based on a change in voltage and displays the temperature measurement on the display.Type: GrantFiled: January 27, 2022Date of Patent: July 18, 2023Assignee: Emerson Digital Cold Chain, Inc.Inventors: Philip Goulis, Gary Sawicki

Publication number: 20230196261Abstract: A flexible sensor label including a reservoir chamber configured to store an activation medium, a plurality of first chambers, and a plurality of second chambers. Each first chamber has an associated first temperature and stores an irreversible thermochromic polymer that is altered and irreversibly changes color in response to the activation medium being released and coming into contact with the irreversible thermochromic polymer in the first chamber and an environmental temperature of the flexible sensor label corresponding to the associated first temperature of the first chamber. Each second chamber has an associated second temperature and stores a reversible thermochromic polymer that is altered and reversibly changes color in response to the activation medium being released and coming into contact with the reversible thermochromic polymer in the second chamber and the environmental temperature of the flexible sensor label corresponding to the associated second temperature of the second chamber.Type: ApplicationFiled: February 23, 2023Publication date: June 22, 2023Applicant: Emerson Digital Cold Chain, Inc.Inventor: Casimir E. LAWLER, JR.

Patent number: 11668495Abstract: Systems and methods are provided and include first and second case controllers for first and second refrigeration cases. The first case controller receives a first air temperature value of the first refrigeration case and communicates the first air temperature value to the second case controller. The second case controller receives a second air temperature value, determine an evaporator saturated suction temperature (SST) value, controls an evaporator pressure regulator based on a comparison of the evaporator SST value with an evaporator SST setpoint, determines an air temperature control value, determines whether the air temperature control value is within a predetermined range of an air temperature setpoint, and adjusts the evaporator SST setpoint in response to the air temperature control value being outside of the predetermined range of the air temperature setpoint.Type: GrantFiled: June 22, 2022Date of Patent: June 6, 2023Assignee: Emerson Digital Cold Chain, Inc.Inventors: Christopher A. Tarbell, Gregory S. Mickelson, Christopher R. Denney

Patent number: 11615367Abstract: A flexible sensor label including a reservoir chamber configured to store an activation medium. The flexible sensor label includes an irreversible chamber configured to store a first indicator medium. The first indicator medium is altered in response to the activation medium being released and the flexible sensor label being exposed to a first condition associated with the first indicator medium. The flexible sensor label includes a reversible chamber configured to store a second indicator medium. The second indicator medium is altered in response to the activation medium being released and the flexible sensor label being exposed to a second condition associated with the second indicator medium.Type: GrantFiled: May 23, 2019Date of Patent: March 28, 2023Assignee: Emerson Digital Cold Chain, Inc.Inventor: Casimir E. Lawler, Jr.

Publication number: 20220180304Abstract: An environment monitoring method including measuring data from a plurality of sensors, wherein each of the plurality of sensors includes a unique identifier (UID). The method further includes instructing each of the plurality of sensors to measure data. The method also includes receiving the measured data from each of the plurality of sensors. The method then calculates a product degradation value of a product based on the measured data and compares the product degradation value with a threshold product degradation value. In response to the product degradation value of the product exceeding the threshold produce degradation value, the method generates and sends an alert to a device.Type: ApplicationFiled: February 28, 2022Publication date: June 9, 2022Applicant: Emerson Digital Cold Chain, Inc.Inventors: Casimir E.
