Abstract: Provided is a control method, an electronic device and a storage medium. The method comprises: when a first yarn spindle with a first identifier is transported on a transport channel and determining that the number of first yarn spindles located in a preset area needs to be detected, detecting the first number of first yarn spindles located in the preset area; and when the first number of first yarn spindles is less than the total number of yarn spindles that the first mechanical arm can grab, determining the target number of first yarn spindles to be replenished, and generating a first control instruction to instruct a second mechanical arm to grab the target number of first yarn spindles from a target trolley associated with the first identifier of the first yarn spindle, and place the target number of first yarn spindles in the transport channel or preset area.

Abstract: A personal gas monitor may include a housing configured to be worn or held by an individual, one or more components secured on or in the housing, and a diagnostic system within the housing and coupled to the one or more components. The diagnostic system tests the one or more components to determine whether or not component (s) are properly functioning.

Abstract: A monitoring system and method include at least one monitor including an internal communication unit, and at least one mobile device that is in communication with the internal communication unit of the monitor. The monitor(s) transmits monitoring data to the mobile device(s) through the internal communication unit. The system and method may also include an external communication unit that is separate and distinct from the monitor(s). The external communication unit receives the monitoring data from the monitor(s) and relays the monitoring data to the mobile device(s).
