Abstract: The present invention discloses a personal handphone system (PHS) handset for children, which comprises a plurality of indicating lamps, a plurality of drawings corresponding to the indicating lamps, a plurality of arrow keys and an enter key for selecting the indicating lamp, a lit indicating lamp being selected by controlling the arrow keys, and a telephone number corresponding to an indicating lamp being stored in a memory of the handset, so that when a phone call is dialed from the handset by pressing the arrow keys to move the lit indicating lamp next to a drawing corresponding to the desired telephone number and pressing the enter key, a microprocessor of the handset reads the telephone number corresponding to the code of the indicating lamp from the memory and dials that telephone number directly.

Abstract: The present invention is to provide a system of increasing communication quality of a PHS handset in a PHS-based communication network including a plurality of PHS handsets each including a first bluetooth module, an indoor Internet phone including a second bluetooth module and a gateway coupled to the second bluetooth module and two different protocols. When the first bluetooth module is connecting to the second bluetooth module, signals received from the network by the Internet phone are transmitted to the gateway and then converted into signals complying with a bluetooth protocol, enabling the second bluetooth module to transmit the same to the PHS handset. The PHS handset is also able to transmit signals complying with the bluetooth protocol to the Internet phone, enabling the gateway to convert the same into the PHS signals and transmit them over the network.

Abstract: A nanoparticle ion detector includes an ion trap that receives charged particles ejected from a mass selection device. A laser beam illuminates the particles to induce fluorescence, which is detected by the photon detector. Particles are periodically dumped from the ion trap. A mass spectrum of the charged particles can be obtained by comparing signals from the photon detector with the particle ejection characteristics of the mass selection device.

Abstract: A mass spectrometer that includes an ion source, an ion trap, and a light detection module. The ion trap has two end-cap electrodes and a ring electrode. The ring electrode is positioned relative to the end-cap electrodes to confine a charged particle from the ion source within a confinement region when an audio frequency voltage having a first amplitude is applied between the ring electrode and the two end-cap electrodes. The charged particle is ejected from the ion trap when the audio frequency voltage increases to a second amplitude. The light detection module includes a light source that illuminates the ejected particle and a light detector that detects light scattered from the ejected particle.

Abstract: A modem having embedded network transmission protocols is provided. A fax/voice/high-speed data transmission 3-way modem is provided with an additional built-in Internet transmission protocol communication module. The communication module includes various Internet protocols (such as PPP, TCP/IP, UDP, HTTP, FTP, POP3, SMTP, etc) and various Internet application services that support those protocols. Moreover, the communication module can also connect to computers through either an internal line-connection end or a parallel/serial port. Furthermore, the network functions of network connection and the desired operations are established in advance under the support of the corresponding BIOS drivers, making the communication module capable of connecting to the network operations independently.

Abstract: A system, a device and their relative methods for displaying the latest messages from an E-mail account under the conditions where there is no need to take the initiative in turning on a computer are disclosed. The incoming E-mail displaying system comprises: a displaying device for displaying new mails arrived from an E-mail box; a mail message service device responsive for searching a mail message in Internet, and responsive for transmitting the mail message through a transmission path; and a switching device responsive to the transmission path for receiving the mail message from the mail message service device and transmitting the mail message to the displaying device. Moreover, the displaying device can be further designed to comprise an input module, a telephone interface end, a displaying module, and a modem having embedded TCP/IP and E-mail client application et cetera functions. That is, enabling the displaying device to make a direct connection to Internet.
