Patent number: 8005565Abstract: A drilling system includes a controller, a human-machine interface, and a drilling device. The controller stores a drilling procedure and a startup mode module for the drilling procedure, and generates an information list which includes location information and corresponding procedure line number for each hole. The human-machine interface is configured for selecting the startup mode module for the drilling procedure, and for inputting a query information corresponding to the selected startup mode module. The controller invokes the corresponding procedure line according to the inputted query information to restart the drilling process to enable the drilling device to return to work.Type: GrantFiled: December 10, 2008Date of Patent: August 23, 2011Assignee: Foxnum Technology Co., Ltd.Inventor: Wei-Der Tang

Patent number: 7886101Abstract: An interruption control system includes two sense elements, a microprocessor, and a controller. The microprocessor includes two registers, two flip-latches, a multiplexer, and a microcontroller. Each sense element senses a device and sends a sense signal. The corresponding register receives and stores the sense signal. The microcontroller sets an identity signal for each of the registers and controls the each of the flip-latch units to record a data signal of the device. The multiplexer alternately outputs the ID signals and the corresponding data signals to the microcontroller to encode into a datagram. The microcontroller sends the datagram to the controller. The controller is interrupted for decoding the datagram.Type: GrantFiled: December 25, 2008Date of Patent: February 8, 2011Assignee: Foxnum Technology Co., Ltd.Inventor: Wei-Der Tang

Publication number: 20100157317Abstract: A testing system for testing dimensions of a cutting tool chosen by a cutting tool choosing device, includes a controller and an optical sensor. The controller includes a cutting tool changing module, a cutting tool control module, and a dimension calculating module. The cutting tool changing module is configured for controlling the cutting tool choosing device to move the cutting tool to a tip initial position above the optical sensor. The cutting tool control module is configured for controlling the cutting tool choosing device to move the cutting tool from the tip initial to the height of a lightbeam of the optical sensor, and moving the cutting tool to pass through the lightbeam of the optical sensor from side to side. The dimension calculating module is configured for receiving the electrical signals from the optical sensor and calculating dimensions of the cutting tool.Type: ApplicationFiled: December 30, 2008Publication date: June 24, 2010Applicant: FOXNUM TECHNOLOGY CO., LTD.Inventor: WEI-DER TANG

Publication number: 20090234898Abstract: The present invention relates to a method of generating a pulse for a digital differential analyzer. The digital differential analyzer includes a counter, a shift register and an adder with a comparator. The beginning number P of the shift register, the beginning number L of the comparator, and the beginning number Q of the counter, are all set, according to the formula Q=int(0.5L+0.5). A pulse command is inputted into the shift register. The number of the shift register and the number of the counter are added. The sum of the addition step is compared to the number of the comparator. If the sum is greater than or equal to the number of the comparator, the digital differential analyzer generates a pulse.Type: ApplicationFiled: September 5, 2008Publication date: September 17, 2009Applicant: FOXNUM TECHNOLOGY CO., LTD.Inventors: RONG-HWANG HORNG, WEI-DER TANG, YAW-SHEN LAI, CHAU-LIN CHANG, TSANN-HUEI CHANG
