Abstract: Proposed is a remote metering system using an ultrasonic water meter, which can minimize power consumption by adopting a low power wide area communication network and a low power design optimized for a power usage according to a transmission cycle when metering data is transmitted by radio so as to extend a replacement cycle of a battery, thereby minimizing maintenance costs due to battery replacement.

Abstract: Disclosed herein is a solar generation facility capable of using high power by configuring packages each including a power pump and a solar module in multiple stages. The solar generation facility includes a plurality of solar module packages connected in series to one another and stacked in multiple layers and at least one condenser corresponding to the solar module packages. At least one of the solar module packages has a solar module that supplies power to a load stage and a power pump that provides lifting power to the solar module. Here, the solar module outputs the power by reflecting the lifting power provided from the power pump.

Abstract: According to certain embodiments of the present disclosure, an electronic device and manufacturing method are disclosed. The electronic device includes: a housing including a first face, a second face, and a side member surrounding a space defined between the first face and the second face, a support member within the housing such that a side face of the support member is oriented towards an inner wall of the side member, a circuit board mounted on one face of the support member, an electrically conductive plate mounted on a second face, and a contact member mounted on the support member to electrically couple at least a portion of the side member to the circuit board, wherein the contact member includes an end portion adjacent to the plate, and an end face of the end portion includes a width smaller than a width of another portion of the contact member.
