Abstract: An electronic device and a method of grip recognition of the electronic device are provided. The electronic device includes an antenna, a radio communication device having a coupler, a memory, and a processor which is electrically connected to the radio communication device and the memory, wherein the memory includes instructions, executable by the processor, wherein the processor is configured to detect a first signal being transmitted and a second signal being received through the antenna using the coupler, calculate a reflection coefficient of the antenna based on the first signal and the second signal, determine a signal magnitude and a phase corresponding to the reflection coefficient, and determine whether the electronic device is being gripped based on the signal magnitude and the phase.

Abstract: An electronic device and a method of grip recognition of the electronic device are provided. The electronic device includes an antenna; a radio communication unit having a coupler; a memory; and a processor which is operatively connected to the radio communication unit and the memory. The memory comprises instructions, executable by the processor. The processor is configured to detect a first signal being transmitted and a second signal being received through the antenna using the coupler, calculate a reflection coefficient of the antenna based on the first signal and the second signal, determine at least one of a signal magnitude or a phase corresponding to the reflection coefficient, and determine whether the electronic device is being gripped based on the at least one of the signal magnitude or the phase.

Abstract: In an optical measurement method, light is directed from a light generator to a light path cell. A light path is generated by continuously reflecting the light between first and second high reflection mirrors within a light path cell that face to each other. An optical signal is detected from an aerosol sample present within a range of the light path. The optical signal is separated into a particle signal and a gas signal by using a statistical methodology. A particle concentration is calculated from the particle signal by using an assumption of an optical particle counter (OPC). A gas concentration is calculated from the gas signal by using optical characteristic data of gas.
