    摘要： An ion source for ionizing a source gas includes an arc chamber housing defining an arc chamber to receive the source gas. The arc chamber has a first region and a second region. An electron emitting device is disposed in the arc chamber adjacent the first region and is adapted to emit electrons into the first and the second regions to ionize the source gas. An electron returning device is disposed in the arc chamber adjacent the second region and is adapted to return at least some of the electrons emitted from the electron emitting device into the second region. A gas supply system is adapted to direct the source gas into the first region and into the second region. According to some embodiments, the gas supply system is adapted to provide a greater mass flow rate of the source gas into the first and second regions than is provided into other regions of the arc chamber.

    摘要： An earring-type microphone to be hung on and used in the ear includes fixing members to be fixed to both ears of a user and a cable formed from an elastic member, of which both ends are respectively positioned at two fixing members, such that one side of the cable comes into close contact with the neck of the user. Speakers are respectively coupled to ends of the cable. A microphone part is provided at one side of the cable for inputting a voice. If force is applied to the microphone part when the user inputs the voice, the cable is stretched such that the microphone part moves from the neck of the user toward the area around the mouth. If the force applied to the microphone part is removed, the microphone part comes into close contact with the area around the mouth by the elastic force of the cable.

    摘要： Methods and apparatuses are provided for determining an interference transmission mode (TM) at a communication device in a cellular communication system using a resource element (RE) defined by frequency and time. A first signal is received in one RE. The first signal comprises a serving signal and an interference signal. A first vector of the received first signal is projected onto each of N projection vectors. A traffic-to-pilot ratio (TPR) decision metric of the interference signal is determined by using N pairs of an actual squared value and an expected squared value which are corresponding to the projected first vector. A TM of the interference signal is detected by determining a TF of the interference signal which minimizes the TPR decision metric from among predetermined transmit format (TF) candidates.
