  • Patent number: 10363331
    Abstract: A sterilization indicator for a sterile container includes a shape-memory element in the form of a compression spring, which, when a predetermined temperature is reached or exceeded, subjects an indicating unit to a defined axial compressive force. The indicating unit is biased by a restoring spring in the counter-direction of the shape-memory element by way of a restoring force which is smaller than the defined axial compressive force. A latching mechanism can be actuated by a closing or locking mechanism of the sterile container. Following or during the closing or locking of the sterile container, the latching mechanism retains the indicating unit in a sterile position, once the unit has been moved into the sterile position by the shape-memory element. Upon opening or unlocking of the sterile container below the sterilization temperature, it frees the indicating unit, whereupon the restoring spring moves the indicating unit back into an unsterile position.

    Abstract: A tamper resistant device comprises a matrix material and a microcapsule in the matrix material. The microcapsule has a first compartment, a second compartment, and an isolating structure separating the first and second compartments. The isolating structure is rupturable in response to a stimulus, such as temperature increases or compressive forces. The first compartment contains a first component, and the second compartment contains a second component. The first and second components react exothermically (produce heat) when in contact with each other. Thus, in some examples, a temperature change in the device resulting from the rupture of the isolating structure in the microcapsule due to physical tampering efforts can be used to trigger a security response.

  • Patent number: 9748062
    Abstract: Malfunction or failure of mechanical, electrical, and electro-mechanical equipment, for example, equipment used in manufacturing operations, is often preceded by an increase in the operating temperature of at least some portion of the equipment. A temperature-sensitive, active material-containing actuator is pre-selected to operate at a pre-determined temperature indicative of impending equipment failure and placed in thermal contact with the equipment. If the equipment achieves the pre-selected temperature the actuator signals this by closing an externally-powered circuit to enable or provide a suitable alarm signal. Additionally, the actuator may close a second circuit connected to a machine controller to alert the machine controller to take some pre-programmed action. Selected actuators are based on shape memory alloys (SMA) adapted to operate over a temperature range sufficient to encompass the expected range of pre-determined temperatures.

  • Publication number: 20140290558
    Abstract: The thaw indicator is a device to determine if a frozen space has gone thru an undesired temperature change and if so remains in an alert position until manually reset even if the temperature corrects itself. It's made up of three major components a base, a piston indicator and a transparent tube. When frozen the thaw indicator looks like a thermometer when unfrozen it looks like a thermometer that has jumped out of its case indicating a change of temperature and state with great certainty. It has been designed to stay out of the way but in plain sight.

  • Publication number: 20140227397
    Abstract: A method for hydrating yeast comprises several steps. A package comprising a thermochromic ink and an indicator is provided. A liquid is provided. The temperature of the liquid is measured by placing the package in contact with the liquid. The liquid is heated or cooled until the thermochromic ink indicates the liquid is within the predetermined temperature range. The liquid and yeast are combined. The package comprises a pouch, a thermochromic ink, and an indicator. The pouch is formed from one or more films sealed together to create an internal space. The thermochromic ink and indicator are arranged relative to each other to indicate when the liquid is within a predetermined temperature range. The thermochromic ink changes color when the liquid is within the predetermined temperature range.

  • Patent number: 8794826
    Abstract: A secure cover for a hot appliance made with heat resistant material having an insulation layer between heat resistant layers that can be stitched with heat resistant thread. The cover prevents users from burning themselves and can be in a shape that covers the hot part of the appliance. The cover has an encasement enclosing a band. The encasement runs along the cover's perimeter and secures the cover on the appliance. The cover may include flares that are used to attach the secure cover to the hot appliance without having the user's fingers approach too close to the hot metal of the appliance. The cover transmits heat, allowing the individual to be aware of the fact that the appliance is hot. The cover may include temperature sensitive fabric, a light indicator or other visual display with a written indication that the appliance is hot.

  • Patent number: 8757503
    Abstract: The invention relates to a method for verifying a time-sensitive and/or temperature-sensitive indicator for marking perishable products. According to said method, the time at which the indicator is activated is detected and stored, the time difference between the stored activation time and a verification time is determined, and verification is made as to whether the change of the indicator occurring during the determined time difference exceeds or falls short of a desired value that depends on the determined time difference. The invention further relates to an indicator for carrying out such a method.

  • Publication number: 20140144366
    Abstract: A temperature-activatable time-temperature indicator that can be used to monitor the historical exposure of a host product to ambient temperatures includes an optically readable, thermally sensitive indicator element. The indicator element can be inactive below a base temperature and is intrinsically thermally responsive at or above an activation temperature which is equal to or greater than the base temperature. The indicator can record cumulative ambient temperature exposure above the activation temperature irreversibly with respect to time. The indicator element can include a synthetic polymeric material, and optionally, a dye. A side-chain crystallizable polymer such as poly(hexadecylmethacrylate), that is solid below the base temperature and is a viscous liquid above the activation temperature can be employed. Intense indicator element colors can be obtained using an appropriate dye or dyes. Various structural configurations of indicator are described and illustrated.
