Patent number: 6899278Abstract: A multi-functional electronic card with a multi-I/O interface has a plurality of interface ports for connecting to a host, at least one functional device, and a multi-interface and multi-functional controller. When an interface prot is inserted into the host, other interface ports are off-line automatically. The multi-interface and multi-functional controller is connected to a multi-I/O interface and the functional devices for selecting one functional device. Signals of the multi-I/O interface are converted into signals of the selected functional device so that the host can access the selected functional device.Type: GrantFiled: November 18, 2002Date of Patent: May 31, 2005Assignees: C-One Technology Corp., Pretec Electronics Corp.Inventors: Caph Chen, Jui-Chung Chen, Ping-Chang Liu

Patent number: 6813668Abstract: A multi-functional electronic card capable of detecting removable cards includes at least one functional device, a controller, a host interface, and a removable card interface. The host interface has a card detecting pin fixed at a level representing that a card is inserted. The removable card interface has an elastic switch connected to the device detecting pin of the controller. The controller detects event and status of a card insertion and removal by a level change of the device detecting pin for setting the event and status in a status register, and informs the host device through the host interface so that the host device reads the status register to determine whether the removable card is inserted or removed.Type: GrantFiled: July 31, 2002Date of Patent: November 2, 2004Assignees: C-One Technology Corp., Pretec Electronics Corp.Inventors: Chien-Chih Tseng, Jui Chung Chen, Ping-Chang Liu, Sidney Young

Patent number: 6778401Abstract: A mini-type connector has a substrate, a plurality of metal joints and a metal frame. The substrate includes a connector and a circuit board, wherein the connector is extended from the circuit board. The plurality of metal joints is assembled to the connector of the substrate for being electrically connected to an external electronic device. The metal frame covers the connector of the substrate for enhancing the stress-resistance strength of the connector. The connector is integrally formed with the circuit board.Type: GrantFiled: May 14, 2003Date of Patent: August 17, 2004Assignees: C-One Technology Corp., Pretec Electronics Corp.Inventors: Gordon Yu, Forli Wen, Justin Cheng

Patent number: 6764017Abstract: A multi-function electronic card has a host interface, a multi-functional controller and a plurality of function devices. Each function device is connected to the host via the host interface by issuing an interrupt request to the multi-functional controller. The multi-functional controller has an interrupt queue and an interrupt status register, each bit of the interrupt status register corresponding to a function device. When a function device issues an interrupt request, an identification number of the function device is stored into the interrupt queue, and only when all the bits in the interrupt status register are zeros, a corresponding bit in the interrupt status register is set as 1 for issuing an interrupt request to the host. When the host has serviced the function device, the interrupt queue is updated and the interrupt status register is cleared.Type: GrantFiled: May 22, 2002Date of Patent: July 20, 2004Assignees: C-One Technology Corp., Pretec Electronics Corp.Inventors: Jui-Chung Chen, Po-Jen Hsueh, Sidney Young, Ping-Chang Liu

Patent number: 6735643Abstract: An electronic card with dynamic memory allocation management is provided, which requires only one single memory by utilizing a dynamic memory controller having a selector and a first, a second and a third base registers. A first DMA controller provides an output address added to the first base register for performing data access. A micro-controller provides an output address added to the second base register for performing data access. A second DMA controller provides an output address added to the third base register for performing data access. When the micro-controller, the first DMA controller or the second DMA controller issues an access request to the memory, the dynamic memory controller selects one of the micro-controller, and the first and second DMA controllers to access the memory based on a sequence of the access requests.Type: GrantFiled: May 22, 2002Date of Patent: May 11, 2004Assignees: C-One Technology Corp., Pretec Electronics Corp.Inventors: Edison Chang, Ellope Shiue, Sidney Young

Publication number: 20040019760Abstract: A non-volatile memory based storage system capable of directly overwriting without using redundancy and its writing method are provided. The invention first writes data into a register. Then, a portion of MCF information of the decoded logical writing destination address is taken as a physical writing address and used to determine whether there is data in a block corresponding to the physical writing address. If yes, a new swap block is taken out from a swap table and at least one record of data in the register is written into the swap block.Type: ApplicationFiled: December 10, 2002Publication date: January 29, 2004Applicants: C-One Technology Corp., Pretec Electronics Corp.Inventors: Chung I.

Patent number: 6646885Abstract: An enhanced electronic card structure includes a circuit board, a top cover board, and a bottom cover board. The circuit board has multiple front front and rear contact points. At least one fixing hole is defined between any two adjacent front contact points. The top cover board has a front edge defined therein multiple gaps, each aligned with one front contact point and corresponding rear contact point. Any two adjacent gaps are separated by a rib, each rib having a bottom face extended thereform a fixing tip aligned with the fixing hole. The bottom cover board has a surface formed thereon multiple fixing joints, each aligned with one fixing tip at the bottom of the rib, so as to make the fixing tip pass through the corresponding fixing hole to be fixed to the corresponding fixing joint.Type: GrantFiled: February 4, 2003Date of Patent: November 11, 2003Assignees: C-One Technology Corp., Pretec Electronics Corp.Inventors: Gordon Yu, Tsung-Kan Cheng, Forli Wen
