Abstract: Provided are an anode for a secondary battery including an anode collector, an anode active material coated on the anode collector, and a non-coating portion (anode tab) which protrudes from one side of the anode collector and is not coated with an anode active material, wherein the anode includes a metal member which is bonded to the non-coating portion and has higher reactivity or reducibility with respect to a metal oxide than the anode collector, and a secondary battery including the anode.

Abstract: A lithium ion secondary battery including a compound containing at least one thiol group (—SH) in a molecule in a unit cell of the battery is provided. By including the compound containing thiol group (—SH) having good reactivity with copper or copper ions, the formation of dendrite through the reduction of copper ions present in the inner portion of the battery or produced during operating the battery at the surface of an anode may be prevented. The internal short between two electrodes due to the dendrite may be also prevented.

Abstract: A mobile communication system includes a signal processor, a first memory, a controller, and an input-output controller. The signal processor receives first forward GPS data and transmits backward GPS data. The first memory has a preamble area, a base station information area, a time information area, and a location information area and stores the backward GPS data, the first forward GPS data, and second forward GPS data received by an exterior GPS receiver. The controller controls data input and output over the first memory and controls transmission of the backward GPS data stored in the first memory to the signal processor. The input-output controller is controlled by the controller and transmits the second forward GPS data to the first memory.

Abstract: A device and method for converting an analog signal into a digital signal using an interleaving sampling operation is described. The device and method includes generating multiple clock signals of the same frequency but with different phases. An input analog signal is compared against multiple reference voltages. For each phase, comparison results are transmitted and decoded into a binary representation of the input analog signal. The decoding also includes the value of the clock phase of the comparison.

Abstract: The present invention relates to a wireless local loop (WLL) system using a patch-type antenna which is provided with microstrips and can be installed indoors. In a WLL system wherein there are provided a base station for relaying transmitted/received signals and a terminal for exchanging these signals between the base station and a telephone or a modem. The present invention includes a patch-type antenna that is detachable/connectable from/to the terminal.

Abstract: A radio pager includes a decoder for decoding coded data transmitted from a central office at a predetermined interval. The decoder classifies the data into one of traffic information and a call number, and informs a control unit of the result. If the identification information of the received data is identical to the identification information stored in the pager, an address decoder stores the traffic information and a call number in a separate address of a memory according to a control signal of the control unit. In addition to traffic information, various information such as weather, stocks, alternate routes, etc., can be transmitted to the pager to increase its usefulness.

Abstract: A communication apparatus for use with a telephone network is provided that includes a DCE controller that controls first and second switches to convert modes based on a transmission/reception state. A mode detector determines whether an applied signal is a voice signal or a data signal. First and second buffers are enabled based on a detection signal from the mode detector to respectively transmit a ring signal or the data signal. A modem controller receives an output signal of the second buffer through the second switch. The DCE controller can receive and apply to an internal processor the output signal from the second buffer via the MODEM controller. Further, an indicator unit that receives the output signal of the second buffer illuminates a light or generates a beeping sound for notification of a received dated signal. Alternatively, a ring generator generates a ring signal for a telephone for a received voice signal.
