20090029472 | Apparatuses and media for drug elution and methods for making and using them - Embodiments of the invention provide to apparatuses and media used in drug elution studies and methods for making and using them. Such methods and materials can be used for example to assess and control the manufacturing process variability of drug eluting implantable devices such as cardiac leads. One embodiment of the invention is a drug elution method that can be used for in-vitro studies of a matrix impregnated with a compound such as a drug blended polymer matrix. A related embodiment of the invention is an apparatus that is used for example to facilitate the practice of the above-noted methods by inhibiting the evaporation of dissolution media from the vessels in which elution is observed. | 01-29-2009 |
20090169624 | Nano-emulsion technology for drug elution - Embodiments of the invention provide to apparatuses and media used in drug elution studies and methods for making and using them.

20090117753 | BODY CONFORMABLE ELECTRICAL NETWORK - An entirely wearable electrical connector for power/data connectivity. The principal element of a modular network is the wearable electrical connector, which is integrated into a personal area network with USB compatibility. | 05-07-2009 |
20090149036 | INHERENTLY SEALED ELECTRICAL CONNECTOR - An entirely wearable electrical connector for power/data connectivity. The principal element of a modular network is the wearable electrical connector, which is integrated into a personal area network with USB compatibility. An embodiment comprises a non-conductive elastomeric environmental seal. | 06-11-2009 |
20090149037 | SELF-IDENTIFYING ELECTRICAL CONNECTOR - An entirely wearable electrical connector for power/data connectivity. The principal element of a modular network is the wearable electrical connector, which is integrated into a personal area network with USB compatibility. Several wearable connector embodiments are disclosed. An enhancement to the wearable connector includes OSI Layer 2 (and potentially Layer 3) functionality. Data Link layer functionality is supported by including electronic serial numbers at wearable snap-connector points. | 06-11-2009 |

20080236010 | Torsion spring base for deflectable sign - A deflectable sign spring base includes a bracket. A torsion spring between walls of the bracket walls includes first and second spring posts. The first spring post contacts a first bracket edge and the second spring post contacts an opposed second bracket edge. Spacing between the first and second edges is greater than the spring post spacing for a non-loaded spring. Spring post engagement with the edges separates the spring posts and induces a torsion spring preload force. A mast engaging member is rotatably connected to the bracket and in continuous contact with both spring posts. The member and mast are continuously urged to a vertical orientation by the torsion spring preload force until acted on by a second force overcoming the preload force, the preload force thereafter returning the member and mast to the vertical orientation after the second force is removed. | 10-02-2008 |

20150115106 | SEPARATION SYSTEM AND BURN WIRE RELEASE MECHANISM FOR TETHERED SPACECRAFT - A tethered spacecraft has a first endmass and a second endmass with a telescoping stacer spring and a tether arranged between the endmasses. The spring is coiled around a center rod and initially contained within a housing, the spring being biased to push the first endmass away from the second endmass. The spring housing is affixed to the first endmass, a first end of the spring being affixed to the spring housing, and tether are affixed to spring at one end and to the second endmass at the other end. A pretensioned loop holds the endmasses abuttingly together, and a burnwire release mechanism cuts the loop to deploy the spring. Upon deployment, the spring extends to its full length to form a cylindrical boom, and the endmasses continue to move outward along the spring centerline until stopped by the tether. | 04-30-2015 |
