Title: Dynamic home agent system for wireless communication systems
Inventor: GORREPATI PATUARDHANA BABU
IPC: H04W8/06
Filed: 2000-08-03
Abstract: The dynamic Home Agent system for wireless communication systems uses the existing infrastructure of the telephony signaling networks and enhanced cellular authentication centers to support dynamic Home Agents, either in visited wireless networks or home wireless networks in a secure manner to provide packet data services to a roaming mobile subscriber station.   Authentication Centers are deployed in these networks as a cellular security mechanism to provide cellular service qualification checks and to prevent cellular fraud by the exchange of confidential keys. The cellular security mechanism is enhanced by the use of an additional key, the Dynamic Mobile IP Key (DMIPKEY) which is used by the dynamic Home Agent in the visited wireless network for authenticating Mobile IP registrations requested by the mobile subscriber station. In ANSI systems, the DMIPKEY can be derived from the Shared Secret Data key or Shared Secret Data part A (SSD_A), since the latter is used for authentication purposes. With necessary CAVE algorithm enhancements, both a mobile subscriber station equipped with the CAVE algorithm and its Authentication Center can independently produce the DMIPKEY. Since the mobile subscriber station is equipped with the CAVE algorithm, the DMIPKEY does not need to be transmitted over the air.

Title: Convertible catheter incorporating distal force transfer mechanism
Inventor: GERBERDING BRENT C
IPC: A61F2/958
Filed: 1999-02-18
Abstract: A method and apparatus for increasing the force transmission from a core wire to a more proximal portion of the catheter, and for directly providing column support at or near the side port of a convertible or rapid-exchange type of catheter. A core wire is typically attached to a proximal portion of a catheter, and extends distally therefrom through a lumen in the catheter. In accordance with the present invention, the core wire has a size and shape relative the lumen of the catheter such that the lateral movement of the core wire is restricted in a restriction region. By restricting the core wire at a distal location relative to the proximal catheter portion, the force transmission from the core wire to the proximal catheter portion can be increased. Further, in a rapid exchange or convertible type configuration, the restriction region may be placed proximate the side hole. By restricting the movement of the core wire adjacent to the side hole, the core wire can provide direct column support thereto reducing the likelihood of kinging or the like at that location.

Title: Molecular regulatory circuits to achieve sustained activation of genes of interest by a single stress
Inventor: VOELLMY RICHARD
IPC: C12Q1/6897
Filed: 1999-05-04
Abstract: The exposure of cells, tissues and organs to "stress", such as elevated temperature, stimulates production of active heat stress transcription factors (HSF), which in turn, induce expression of genes regulated by stress promoters. Normally, the activity of stress promoters declines after cells, tissues and organs are returned to a normal condition. Mutant forms of HSF, however, can constitutively transactivate stress genes, in the absence of stress. By taking advantage of such mutant HSF, molecular circuits can be devised to provide a sustained expression of a gene of interest using a single application of stress. One form of molecular circuit comprises (a) a first nucleic acid molecule that comprises a gene encoding a transcription factor and a promoter activatable by stress and by the transcription factor, wherein the stress-activatable promoter and the transcription factor gene are operably linked, and (b) a second nucleic acid molecule that comprises a gene of interest and a second promoter activatable by the transcription factor, wherein the second promoter and the gene of interest are operably linked.
