Abstract: A proximity sensor is provided with multiple channels and a proximity sensor chip (IC) connected to the multiple channels through a sensing line. The proximity sensor chip (IC) includes an internal temperature sensor, senses a first sensing value through the multiple channels, senses a second sensing value through the internal temperature sensor, and compensates the first sensing value through addition or subtraction of the second sensing value with respect to the first sensing value. The internal temperature sensor includes: a clock signal generator including a first oscillator and generating first clock signals variable according to temperature characteristics; and a temperature compensator generating second clock signals according to a setting condition corresponding to the first clock signals generated from the clock signal generator and outputting the second sensing value by counting the second clock signals through a second oscillator generating reference clock signals independent of temperature change.

Abstract: Disclosed herein are grip sensing method and apparatus. The grip sensing method includes generating a sensing count by differentially amplifying a voltage potential of a grip channel based on a predetermined correction offset and performing digital conversion, comparing the sensing count with a predetermined base value to determine whether a touch condition is satisfied, performing baseline tracking for determining a baseline count based on the sensing count when the sensing count is less than the base value and the touch condition is not satisfied, stopping the baseline tracking and performing temperature compensation with respect to the baseline count using a temperature sensor mounted therein when the sensing count is equal to or greater than the base value and the touch condition is satisfied, and sensing an event based on the sensing count and the temperature-compensated baseline count.

Abstract: The present invention relates to a method of simultaneously performing packet detection, symbol timing acquisition, and carrier frequency offset estimation in parallel using multiple correlation detection and a Bluetooth apparatus using the same, in which the Bluetooth apparatus receiving a frequency modulated signal includes a frequency demodulating unit converting the received signal into a similar amplitude modulated signal; and multiple correlation detectors generating multiple correlation indices from the converted signal, on a basis of an access address received from a link layer and a plurality of carrier frequency offset search windows. According to the present invention, since packet detection, symbol timing acquisition and carrier frequency offset estimation are simultaneously performed in parallel in the relatively long access address reception interval instead of the short preamble signal reception interval.

Abstract: The present invention relates to a method of detecting an access address of a physical channel in a Bluetooth signal to which channel coding is applied, the method including: performing initial signal processing in a unit of a specific length in a preamble section of a Bluetooth signal; and performing channel decoding in the specific length for a preamble part remained after the initial signal processing, wherein the specific length is a bit pattern length of a bitstream which is repeated in the preamble section or a length of a bitstream input for channel decoding. According to the present invention, channel decoding is performed in a unit of a bit pattern length of an access address from the remaining preamble part, and thus detection of the access address is available even though a start point of the access address is not provided.
