Abstract: Methods, apparatuses, systems, computer readable media, and a computer product for detecting a gas leak of a gas tank. In a method, at least one inside temperature is determined for the gas tank based on a plurality of outside temperatures that are collected outside the gas tank, the at least one inside temperature being estimated for at least one inside position within the gas tank during an operation of the gas tank. A gas pressure within the gas tank under a standard temperature is obtained based on the at least one inside temperature. The gas leak of the gas tank is detected based on the gas pressure.

Abstract: Embodiments of present disclosure relate to a switchgear assembly and a switchgear. The switchgear assembly comprises a housing comprising an internal space filled with an insulating gas; and a plurality of circulating tubes arranged on the housing, each of the plurality of circulating tubes comprising a gas inlet and a gas outlet in fluid communication with the internal space, wherein the gas inlet of each of the plurality of circulating tubes is arranged at a position higher than the respective gas outlet such that the insulating gas is circulated between the housing and the plurality of circulating tubes.

Abstract: A method of processing air quality data includes: receiving air indicator data collected by one or more air quality sensors, wherein the one or more air quality sensors are detachably coupled to a hardware base of the air quality monitoring station via one or more data communication interfaces, and the hardware base is communicably coupled to a remote server over a network; generating air quality data according to the air indicator data, wherein the air quality data is derived from air indicator data received from one or more air quality sensors over a distance traveled by the one or more air quality sensors; and sending the air quality data, via the hardware base, to the remote server.

Abstract: A movable touch module and an electronic device using the same are provided. The movable touch module is disposed at a main body and includes a suspending element, a touch unit, a four-direction sensing element, and at least two rotation sensing elements. The suspending element is disposed at the main body and is movable relative to the main body on a plane. The suspending element has a plurality of elastic portions against the main body. The touch unit is fastened to the suspending element. The four-direction sensing element and the rotation sensing elements are fastened to the main body. When the suspending element moves along a direction on the plane, the suspending element triggers the four-direction sensing element along the direction. When the suspending element rotates on the plane, the suspending element correspondingly triggers one of the rotation sensing elements.
