Patent number: 9974642Abstract: An expandable vascular sheath utilizes a set of expandable members such as shape memory alloy wires for expanding its distal end. The wires are slidable along a portion of the sheath's elongate shaft. In certain embodiments, the distal end of the shaft is manufactured with a more pliable and elastic polymer relative to more proximal portions of the elongate shaft, so that as the wires advance into distal portions of the shaft, they expand, causing the distal end opening of the shaft to expand. A method for retrieving a foreign object from a vasculature utilizes a retrieval tool that can be advanced through the expandable vascular sheath.Type: GrantFiled: April 18, 2016Date of Patent: May 22, 2018Assignee: The Regents of the University of CaliforniaInventors: Bashir Akhavan Tafti, Edward W. Lee, Stephen T. Kee

Publication number: 20160346074Abstract: The present invention relates to a device for filtering obstructive material within the vasculature of a subject. The device includes a frame with multiple flexible legs connected to a hub, and a web that is positioned between the legs. The web is substantially perpendicular to the central axis. The legs are compressible about the central axis when the frame is in a compressed state, and the legs expand away from the central axis such that the web is held taut when the legs are in an expanded state. In certain embodiments, the web is a single piece of thread that passes through openings in the legs. In certain embodiments, a heat shrink material is used to secure a thread of the web to the frame.Type: ApplicationFiled: August 11, 2016Publication date: December 1, 2016Inventors: Bashir Tafti, Edward W.

Patent number: 7873837Abstract: An electronic data flash card includes a random number generator that generates a random number stored in the card and a host system each time the card is accessed by the host system. The random number is used by the host system to encrypt a logical branch address, a user password, and user data that is written to and stored in a secure area of the card. The random number is encrypted using a key associated with the card, and the encrypted random number is stored by the card with the associated encrypted data. The random number is not stored in the host system. A new random number is generated each time the card is queried. In a read process the host system decrypts the encrypted random number using the key, then uses the random number to decrypt the associated encrypted data. Access to read/write processes are password protected.Type: GrantFiled: March 12, 2007Date of Patent: January 18, 2011Assignee: Super Talent Electronics, Inc.Inventors: Charles C.

Patent number: 7814337Abstract: A secure flash-card reader reads a user ID from a secure card and finds a matching entry with a hashed password in a user table on the reader. An encrypted key is received from a secure host that hashes and encrypts a password the user types into the host and the user's ID. A card decryption engine uses a random number to decrypt the encrypted key and recover the hashed password and user ID from the secure host, which is compared by a comparator to the hashed password and user ID from the user table. A mismatch causes an access controller to block access to encrypted data on the secure card. Flash data is transferred over a flash-serial buffer bus between flash-card controllers and a RAM buffer. An encryption engine on the flash-serial buffer bus encrypts and decrypts data and connects to a serial engine to the host.Type: GrantFiled: January 17, 2007Date of Patent: October 12, 2010Assignee: Super Talent Electronics, Inc.Inventors: Charles C.

Patent number: 7788553Abstract: A high volume testing/formatting process is provided for Universal Serial Bus-based (USB-based) electronic data flash cards (USB devices) that meets the increasing demand for USB electronic data flash cards (USB devices). A test host is simultaneously coupled to the multiple USB devices (e.g., using a multi-port card reader or a probe fixture), a controller endpoint value is read from each of the USB devices and verified with a known good value, and then testing/formatting is performed on each of the USB devices by writing predetermined data into each USB device in a pipelined manner, then reading out and testing the predetermined data. In one embodiment, the test host implements a special USB driver that blocks standard USB registration procedures upon detecting the plurality of USB devices. Control and/or boot code data are written onto the flash memory device (i.e., instead of being provided on a controller ROM).Type: GrantFiled: October 11, 2007Date of Patent: August 31, 2010Assignee: Super Talent Electronics, Inc.Inventors: David Q.

Patent number: 7702831Abstract: An electronic data flash card is accessible by a host computer, and includes a processing unit connected to a flash memory device that stores a data file, and an input-output interface circuit activated so as to establish a communication with the host computer. In an embodiment, the electronic data flash card uses a USB input/output interface circuit for communication with the host computer. A flash memory controller includes an index for converting logical addresses sent by the host computer into physical addresses associated with sectors of the flash memory device. The index is controlled by arbitration logic referencing to values from various look up tables and valid data stored in the flash memory device. The flash memory controller further includes a first-in-first-out unit (FIFO) for recycling obsolete sectors of the flash memory device in the background process so that they are available for reprogramming.Type: GrantFiled: August 23, 2006Date of Patent: April 20, 2010Assignee: Super Talent Electronics, Inc.Inventors: Abraham C.
