A defrost or thaw measuring device has a dumbbell or hourglass-shaped rotatable compartment with a cavity, the cavity being partly filled with at least two phase change materials having different melting points. The measuring device may determine the time period of thawing at two or more temperature intervals in the refrigeration space.

A circuit device includes an oscillation circuit and a processing circuit. The oscillation circuit includes a variable capacitance circuit configured by a capacitor array and oscillates at an oscillation frequency corresponding to the capacitance value of the variable capacitance circuit. First temperature data and second temperature data subsequent to the first temperature data are input to the processing circuit as temperature data. In the period between the start of the capacitance control based on the first temperature data and the start of the capacitance control based on the second temperature data, the processing circuit switches the first capacitance control data corresponding to the first temperature data and the second capacitance control data different from the first capacitance control data in a time-division manner to be output to the variable capacitance circuit.

An apparatus for providing negative-pressure therapy may comprise a negative-pressure chamber and a pneumatically-actuated service timer, which can be used to indicate an expiration or other service condition of the apparatus. The apparatus may further comprise an actuator operable to engage a timer fluid with a migration medium. The timer fluid and the migration medium may be selected so that migration time through the migration medium corresponds to an expiration condition of the apparatus. The timer may also provide indicia of migration progress or termination.

The invention discloses a bedroom desk decoration, which includes a bottom plate, and a decorative shell is fixedly mounted on the top end surface of the bottom plate. A rotation ring is mounted on the left end surface of the decorative shell to start a motor. The rotation of the second gear drives the first gears on the left and right sides to rotate in opposite directions to achieve the rotation of the spiral ornament to add decorative effects. The rotation of the fourth bevel gear drives the rotation of the fifth bevel gear, and the rotation of the fifth bevel gear drives the toggle. The slider can pull the pull wire to make the spring expression package jump up and down automatically. It can dynamically display various decorative accessories, improve the effect of decompression, and add pens. Pen holder reduces desktop space and improves desktop cleanliness.
