Title: Mobile communication terminal having fluorescent key pad
Inventor: CHOI WOO HYUK
IPC: H04B1/38
Filed: 1998-12-31
Abstract: PURPOSE: A mobile communication terminal having a fluorescent key pad is provided to reduce a battery consumption by maintaining a light for a predetermined time in case of a backlight-off, and coats a fluorescent material in each key button of a terminal. CONSTITUTION: A mobile communication terminal includes a fluorescent key pad(20), a backlight driver(21), and a control part(17). The backlight turns on a background illumination in order to discriminate a printed character or a printed number of a key pad without relation to a surrounding illumination degree. The fluorescent key pad(20) includes a number key and a function selection key on which a fluorescent material is coated in each key button. The backlight driver(21) turns on/off a light emitting diode(LED) according to a predetermined level signal. If a key input of the fluorescent key pad is detected under the condition that the backlight function is set, the control part(17) applies a predetermined level signal to the backlight driver for a predetermined time. If the predetermined time elapses, a predetermined level signal is applied to the control part(17). Thereby, a battery consumption is reduced by maintaining a light for a predetermined time in case of a backlight-off.

Title: Modular multiplication method using systolic array
Inventor: LEE KWANG HYUNG
IPC: G09C1/00
Filed: 1999-02-23
Abstract: PURPOSE: Because a systolic array that Walter suggested has a defect that other bits except for a carry bit inside of each processing element(PE) should wait until the carry bit is calculated, in a secret key or a public key cipher algorithm it takes a long time to decipher the cipher and there is a problem inappropriate to a design of an exclusive use chip to optimize the public key algorithm. A modular multiplication method using a systolic array is for an improvement in efficiency of the Walter's modular multiplier using the systolic array to accomplish the modular multiplication effectively. CONSTITUTION: A carry bit is not calculated in the end of a PE, but the calculation is processed in the next PE in parallel. And, the number of passing gate levels of the PE is reduced by using a multigate to process the same operations in one gate, so the modular multiplication method using the systolic array helps to design the PE having an advanced efficiency.
