| 20110131639 | Secure PIN Management of a User Trusted Device - A mechanism is provided for secure PIN management of a user trusted device. A user trusted device detects a memory card coupled to the user trusted device. The user trusted device receives user input of an external PIN (ext_PIN). The user trusted device identifies a key (K) associated with the external PIN, wherein the key is stored in the persistent memory. The user trusted device computes a card PIN (card_PIN) using a function (f) and the key as stored on the persistent memory, wherein the card PIN is computed using the following equation: card_PIN=f(K, ext_PIN). The user trusted device unlocks the memory card using the card PIN, thereby forming an unlocked memory card. | 06-02-2011 |

| 20080214999 | ANGIOPLASTY DEVICE AND METHOD OF MAKING SAME - An angioplasty device and particle trap for use in removal of a particle from a small diameter vessel or vessel-like structure is disclosed. One embodiment includes a catheter for insertion into a vessel-like structure, the catheter having a catheter wall and a movable member, a trap operably connected to the catheter wall and to the movable member, wherein relative motion between the catheter wall and the movable member actuates the trap. In one embodiment, the expanded trap is formed from struts in a spiral-shaped configuration. In one embodiment, the contracted trap forms a waist to creates a pinch-point to trap particles. In one embodiment, the contracted trap forms a cocoon-like structure to further trap particles. In one embodiment, the angioplasty device includes a handle to actuate the trap from a contracted position to an expanded position and return to a contracted position. The handle provides rotational or longitudinal or both types of movement to actuate the trap. | 09-04-2008 |

| 20080221611 | EMBOLIC PROTECTION DEVICE HAVING EXPANDABLE TRAP - An embolic protection device for use in medical, veterinary, non-medical or industrial applications where removal of an obstruction from a small diameter vessel or vessel-like structure could produce particles, which, if allowed to remain in the vessel, could cause undesirable complications and results. One embodiment comprises a catheter for insertion into a vessel and a trap operably connected to the catheter and to a rotatable member. Rotating the rotatable member relative to the catheter actuates the trap. One embodiment comprises a rotatable member that actuates a flexible strut between an arcuately expanded position and a helically twisted position, and a membrane operably connected to the flexible strut. | 09-11-2008 |
| 20110172597 | Embolic Protection Device Having Expandable Trap - An embolic protection device for use in medical, veterinary, non-medical or industrial applications where removal of an obstruction from a small diameter vessel or vessel-like structure could produce particles, which, if allowed to remain in the vessel, could cause undesirable complications and results. One embodiment comprises a catheter for insertion into a vessel and a trap operably connected to the catheter and to a rotatable member. Rotating the rotatable member relative to the catheter actuates the trap. One embodiment comprises a rotatable member that actuates a flexible strut between an arcuately expanded position and a helically twisted position, and a membrane operably connected to the flexible strut. | 07-14-2011 |
