Patent number: 7930531Abstract: A multi-partition Universal Serial Bus (USB) device has a flash memory with multiple partitions of storage. Some partitions are for different operating systems and store OS images. Another partition has a control program while a user partition stores user data and user configuration information. The control program can test the multi-partition USB device and instruct the host computer BIOS to mount a partition from its flash memory as a drive of the host computer. The host computer can then be rebooted. The OS image from the flash memory is loaded into main memory during rebooting, and the host computer executes a new operating system using the new OS image. The user can press buttons on the multi-partition USB device to select which OS to load, and to begin rebooting. Virus removal programs in the alternate OS can help recover from a virus in the primary OS.Type: GrantFiled: August 13, 2007Date of Patent: April 19, 2011Assignee: Super Talent Electronics, Inc.Inventors: David Q.

Patent number: 7126559Abstract: A multi-light-emitting diode (LED) display for a USB flash drive produces a visually dazzling display. When accessed, a USB flash controller drives pulses onto an activity signal that increments a counter on a pattern-decoding generator. The pattern-decoding generator decodes the count and drives signals to data outputs. The data outputs connect to LED's, turning LED's on and off according to a display pattern. The pattern can be programmed by the USB flash controller into the pattern-decoding generator, or can be a hardwired pattern. Marquee patterns having a lit LED appearing to move down a line of LED's have more visual appeal than single LED indicators. Each data line can drive two LED's in different parts of a dual display, reducing costs. Multi-color LED's can be used to improve variety. The multiple LED's and the pattern-decoding generator can be mounted on a flexible PCB.Type: GrantFiled: December 24, 2003Date of Patent: October 24, 2006Assignee: Super Talent Electronics, Inc.Inventors: Ching-Jong Su, Sun-Teck See, Tzu-Yih Chu

Patent number: 7023700Abstract: A memory module has a two-plate heat sink attached by rivets. A front plate contacts the flat surfaces of memory chips on a front surface of the module printed-circuit board (PCB) substrate, while another back plate contacts chips on the back surface of the substrate. The plates contact the substrate along the top edge opposite the connector edge, and along the upper half of the substrate's side edges. Holes in the substrate allow for rivets or other fasteners to pass through to firmly attach the plates to the substrate, prevent wobble. Four top-edge slots are cut in the plates near the top edge, between the rivets along the top edge. The top-edge slots allow air to flow underneath the plates, in small gaps between memory chips, and between the plate and the substrate. The added air flow underneath the plates helps cool the heat-sink plates, reduce hot spots and failures.Type: GrantFiled: December 24, 2003Date of Patent: April 4, 2006Assignee: Super Talent Electronics, Inc.Inventors: Ren-Kang Chiou, Tzu-Yih Chu

Patent number: 6993618Abstract: A flash-card exchanger has two modes of operation. When a host personal computer (PC) is connected to a Universal-Serial-Bus (USB) connector, the flash-card exchanger operates in a card reader mode, allowing the host to read data from removable flash-memory cards inserted into connector slots of the flash-card exchanger. When the host PC is not connected, a USB flash-memory thumb or key-chain drive can be inserted into a second USB connector. A USB dual-mode microcontroller acts as a USB host, reading data from the removable flash-memory card and writing the data to the USB-memory key drive using USB packets. Since the USB-memory key drive is small and removable, the user can upgrade to larger storage capacities by plugging in a larger-capacity USB-memory key drive. A flash-exchanger program executing on the USB dual-mode microcontroller copies data from an input-output bus and generates USB packets to the USB-memory key drive.Type: GrantFiled: January 15, 2004Date of Patent: January 31, 2006Assignee: Super Talent Electronics, Inc.Inventors: Ben Wei Chen, Tzu-Yih Chu, Sun-Teck See

Patent number: 6933209Abstract: Memory chips are assembled into a stack with an insertion-pin frame between pins of two stacked memory chips. The insertion-pin frame is not bent or formed into 3-dimensional shapes but is flat, improving use in standard surface-mount processes such as solder printing onto the insertion-pin frame. Flat insertion pins held to the flat insertion-pin frame by necks are soldered to top shoulders of pins on a lower chip. Then bottom feet of pins of an upper chip are soldered to the insertion pins. The necks are punched away or broken to release the insertion-pin frame from the insertion pins that are soldered to the assembled stacked chips. An insulated wire jumper can be placed under the pins to jumper chip-select connections, or a bridge between insertion pins can be formed from the insertion-pin frame. Holding tabs to the bridge are removed with the insertion pins or by punching.Type: GrantFiled: December 24, 2003Date of Patent: August 23, 2005Assignee: Super Talent Electronics Inc.Inventors: Ren-Kang Chiou, Tzu-Yih Chu
