The present invention relates to a wire rope diagnostic device that is capable of being fastened or unfastened by means of battery packs, and more specifically, to a wire rope diagnostic device for performing safety diagnosis of a wire rope used for a lifting device such as a crane, an elevator, a water gate, and the like in real time that is capable of being fixedly fastened by means of battery packs so that it can be simply installed and separated and allow the battery packs to be easily exchanged.

Wire rope diagnostic device that can be engaged using battery packs

Provided is a method and system for collecting sensor data using a data channel and a control channel. The method and system construct an appropriate and efficient communication environment when there are several sensors corresponding to one gateway in order to collect measured data from the sensors, by using a separate control channel for general control communication and a data channel for data communication to transmit data after confirming whether the data channel is available through the control channel in the communication between a gateway and sensors.

Method and system for collecting sensor data using data channel and control channel

An electronic device is provided that includes an antenna configured to receive a first signal and transmit a second signal. The electronic device also includes a transceiver configured to perform frequency conversion of the first signal and the second signal. The electronic device further includes a coupler path configured to transmit the second signal to the transceiver via a coupler, and a receive path configured to transmit the first signal, obtained from the antenna, to the transceiver. The electronic device also includes a switching unit configured to be connected with the transceiver and switch between the coupler path and the receive path.

Wireless communication device and method for supporting transceiver performance by switching between a coupler path and receive path

Disclosed in an embodiment is a light emitting device comprising: a light-emitting structure having a first semiconductor layer, an active layer under the first semiconductor layer, and a second semiconductor layer under the active layer; a first contact layer disposed under the light-emitting structure; a reflective layer disposed under the first contact layer; a first electrode layer including a capping layer disposed under the reflective layer; a second electrode layer electrically connected with the first semiconductor layer; a protective layer disposed at the outer peripheral portion between the capping layer and the light-emitting structure; a barrier layer at an outer side of the reflective layer and made of a metal different from that of the reflective layer; and a support member disposed under the capping layer.

Light-emitting device and light-emitting device package having same

A semiconductor device package and a lighting device including a semiconductor device package are provided. The semiconductor device package may include a substrate, a first electrode module provided on the substrate, a light emitting device provided in a first region of the first electrode module, a second electrode module electrically disconnected from the first electrode module and provided on the substrate, and an insulating reflection layer provided on a circumference of the light emitting device between the first electrode module and the second electrode module and having a polygonal shape.
