    • Disclosed herein is a passive Radio Frequency Identification (RFID) reader supporting a dense mode. The RFID reader includes a modulator, a Radio Frequency (RF) transmitter, an RF receiver, a demodulator, a coupler, a scan receiver, and a microcontroller. The modulator encodes and modulates interrogation signals, and converts resulting signals into analog signals. The RF transmitter performs frequency up-conversion and power amplification on the analog signals, and radiates resulting signals. The RF receiver receives response signals from tags, and performs frequency down-conversion and then power amplification on the response signals. The demodulator converts the response signals into digital signals, and demodulates and decodes the digital signals. The coupler samples interrogation signals from other readers. The scan receiver scans the frequency channels of all sampled interrogation signals. The microcontroller receives the results of the scanning, detects a currently unoccupied frequency channel, and communicates with a tag using the detected frequency channel.
    • 本文公开了一种支持密集模式的无源射频识别(RFID)阅读器。 RFID读取器包括调制器,射频(RF)发射器,RF接收器,解调器,耦合器,扫描接收器和微控制器。 调制器对询问信号进行编码和调制,并将结果信号转换为模拟信号。 RF发射机对模拟信号进行上变频和功率放大,并辐射出结果信号。 RF接收机从标签接收响应信号,并对响应信号进行频率下变频,然后进行功率放大。 解调器将响应信号转换为数字信号,并对数字信号进行解调和解码。 耦合器对来自其他读取器的询问信号进行采样。 扫描接收机扫描所有采样询问信号的频道。 微控制器接收扫描结果,检测当前未被占用的频道,并使用检测到的频道与标签进行通信。

    • Disclosed herein is an automatic lubrication device for automatically supplying grease to a hydraulic breaker. The device is designed to supply a predetermined amount of grease to requisite components in a constant striking period by use of a pressure difference in a space above a piston within the breaker where a high pressure and a low pressure are alternately generated according to strike of the piston. The device comprises an input mechanism re¬ ciprocating whenever the breaker strikes for transmitting strike and force thereof to a compressing mechanism, the compressing mechanism for converting reciprocation of the input mechanism into rotation and compressing a spring of a pumping mechanism, the pumping mechanism compressed by amplified force of the compressing mechanism and pumping the grease in the constant striking period, and a filling mechanism for supplying the grease to the pumping mechanism while containing the grease.
