Abstract: A method can be used for detecting a potential presence of an object by a reader capable of mutually communicating via a contactless communications protocol. An antenna of the reader transmits a magnetic field on a carrier signal having a sub-carrier modulated by a first data sequence. The modulated sub-carrier is non-interpretable by the object. The antenna of the reader receives a signal resulting from the transmission. The reader demodulates the sub-carrier of the resulting signal so as to extract a second data sequence from the resulting signal. The first data sequence and second data sequence are correlated and the potential presence or absence of the object is determined based upon the result of the correlating.

Abstract: Using inductive currents to wirelessly charge a device via a device connected to a power source. This inductive charging may result when a first mobile device recognizes a second mobile device via a wireless connection (e.g., Bluetooth, Bluetooth Low Energy (BLE), Near-Field Communication (NFC), or the like). An application stored on the first mobile device may recognize a second mobile device by transmitting an advertising packet when the first mobile device is connected to a power source. An advertising packet may be received by the second mobile device and the second mobile device may transmit a response to the advertising packet in order to generate a connection between the first and second mobile devices. The response may include data such as, connection strength, response time, connection preferences, and the like. Upon detection and connection, the second mobile device may be wirelessly charged by the first device via inductive charging.

Abstract: Provided is a high frequency module capable of reducing the IMD. During the transmission/reception operation based on W-CDMA, control signals VSWCC, VTRXCC are output as Hi signals from a control logic. Consequently, transistor T1 is turned ON, and transistors T2, T3 are respectively turned OFF. When the transistor T1 is turned ON, the voltage output from an operational amplifier is output as the signal VVSW to a control terminal, and the control signal VTRXC is output as a Hi signal. The signal VVSW is of a voltage level that is lower than that of the control signal VTRXC. The control signal VTRXC is a signal for turning ON a transistor circuit Q1, and the signal VVSW is a signal for supplying a DC voltage to the antenna potential. It is thereby possible to reduce the ON resistance of the transistor circuit Q1 and improve the IMD characteristics.
