  • Publication number: 20240128291
    Abstract: A sensor package structure includes a substrate, a sensor chip disposed on and electrically coupled to the substrate, a light-permeable layer, an adhesive layer having a ring-shape and sandwiched between the sensor chip and the light-permeable layer, and an encapsulant formed on the substrate. The adhesive layer has two adhering surfaces having a same area and a middle cross section located at a middle position between the two adhering surfaces. An area of the middle cross section is 115% to 200% of an area of any one of the two adhering surfaces. The adhesive layer can provide for light to travel therethrough, and enables the light therein to change direction and to attenuate. The sensor chip, the adhesive layer, and the light-permeable layer are embedded in the encapsulant, and an outer surface of the light-permeable layer is at least partially exposed from the encapsulant.

  • Publication number: 20240087057
    Abstract: A power consumption monitoring device includes a sensor, a storage, and a processor. The sensor is configured to detect a power-consuming device quantity and a power consumption amount. The storage is configured to store the power-consuming device quantity and the power consumption amount. The processor is communicatively connected to the sensor and the storage. The processor is configured to calculate a power-consuming device idling indicator based on the power-consuming device quantity and the power consumption amount in a monitoring time interval, wherein the power-consuming device idling indicator is used for indicating a deviation status of the power-consuming device quantity and the power consumption amount. The processor is further configured to determine whether the power-consuming device idling indicator exceeds a warning threshold. In response to the power-consuming device idling indicator exceeding the warning threshold, the processor is further configured to generate a warning message.
