  • Patent number: 9847189
    Abstract: A push lock switch apparatus is provided. The apparatus includes a plunger that is inserted in a housing and slides and includes a moving passage in the inside thereof. A lock pin is hinged at a bottom portion of the housing and interferes with the moving passage to regulate the slide movement of the plunger. A return spring is disposed in the housing and is able to provide an elastic force to the plunger and allows the lock pin to rotate on the moving passage by pressurizing the lock pin. Additionally, a movable contactor is engaged with the plunger and slides together with the plunger and contacts a fixed terminal disposed at an outer side of the housing when the plunger slides.

  • Patent number: 9748912
    Abstract: Provided is a Radio Frequency (RF) communication apparatus and a method for detecting power. The RF communication apparatus includes a receiver that receives a segment value indicating one of multiple transmission output power ranges, a power detector that detects a strength of an RF transmission signal in an output power range corresponding to the segment value, and a transmitter that transmits the strength of the detected RF transmission signal. The power detector includes a feedback unit that receives the fed-back RF transmission signal, an RF core unit that generates a Root Mean Square (RMS) of the RF transmission signal, and a converter that converts a current signal corresponding to the RMS of the RF transmission signal into a voltage signal, and converts the converted voltage signal from a differential signal to a single signal.
