Title: Digital-to-analog converter and related method with 1's complement current supply structure for simplifying control logic
Inventor: LIN ROGER
IPC: H03M1/66
Filed: 2003-06-12
Granted: 2004-09-21
Abstract: A digital-to-analog converter generates an output voltage according to an input code. The converter includes: a plurality of positive current sources, a plurality of negative current sources, an assistant current source, and a control logic. The control logic converts the input code to a plurality of positive control bits and negative control bits for respectively controlling the positive current sources and the negative current sources so a current can be provided to a resistor for achieving the purpose of to establishing the required output voltage. The assistant current source also provides current to the resistor when the negative current sources provide current. When the input code is a 2's complement negative number, the control logic simply codes a 1's complement number to generate the negative control bits according to the input code such that the converter provides a negative output voltage according to the negative input code and the assistant current source.

Title: Glass cutting device
Inventor: WANG RUNG-SHAN
IPC: C03B33/037
Filed: 2003-06-16
Granted: 2004-06-11
Abstract: A glass cutting device includes a cutter wheel, a laser source, and a cooling tube nozzle set collinearly assembled on a substrate. The cutter wheel performs a cutting operation on a glass substrate forming a cutting crease. A laser beam from the laser source performs a local heating operation along the crease. Finally, a cooling fluid from the cooling tube nozzle performs a quenching operation along the crease so that the glass substrate cracks along the crease due to the stress generated by the thermal contraction and expansion of the glass substrate without the need of using a foreign force. Thus, the present invention simplifies the glass cutting process while avoiding the formation of irregular cracking, thereby increasing the dimensional precision of the product. Furthermore, the use of a laser source for local heating can also avoid the secondary contamination by molten crumbs.

Title: Non-quadratic modulus method and apparatus
Inventor: WEN JYH-HORNG
IPC: G06F17/10
Filed: 2003-12-31
Granted: 2005-05-21
Abstract: A non-quadratic modulus algorithm and apparatus realized by the congruence theorem for a divider. The divider is applicable to the frequency hopping (FH) scheme of the wireless communication spreading spectrum system to calculate a remainder of a dividend S divided by a modulus N. A smallest quadratic number (2<k>, wherein k is a whole number) greater than the modulus N is chosen as the divisor Y, and a quotient Q and reminder B is determined by shifting the dividend S, wherein the relationship is S=Y*Q+B. By canceling a multiple of the modulus (i.e. N*Q) from the dividend S to obtain a new dividend S', the dividend for calculation is diminished. The reminder of S divided by N is obtained by repeating the above procedures for diminishing the dividend.
