  • Publication number: 20050088112
    Abstract: A dimmer fixture has a ballast board 10, a main board 40 and switch 70. The ballast board and main board have no inductors so the fixture may be used for fluorescent and incandescent lamps. The ballast board 10 has two bridge circuits 14, 16 and two dc voltage regulators. A delay circuit 24 prevents the VCO 26 for operating for long enough to allow fluorescent lamps to warm up. The main board has four power MOSFETS or IGBTs. One of devices Q1 and Q2 is always on. One of devices Q3, Q4 completes the drive to the lamps. Control signals on ballast board 10 operate the power devices Q1-Q4.

  • Publication number: 20030091013
    Abstract: Disclosed is an authentication method between a mobile node (MN) and a home agent (HA) in a wireless communication system supporting packet communication. The wireless communication system includes the HA, a foreign agent (FA) connected to which the MN assigned a Mobile IP address, and first and second servers provided respectively to the HA and the FA for authentication. Upon receiving a Registration Request message from the MN, the FA generates an Access Request message and transmits the generated Access Request message to the first server through the second server. Upon receiving the Access Request message, the first server generates an authentication shared key with a preset number and transmits the generated authentication shared key to the FA through the second server. The FA authenticates the Registration Request message according to the authentication shared key and transmits the authenticated Registration Request message to the HA.

  • Patent number: 5769839
    Abstract: System and method for storing packed red blood cells (RBCs) long-term in a non-extractable plastic blood storage bag in a hypotonic cell preservation solution, for subsequent human parenteral introduction of the stored red blood cells. In addition, a blood storage bag that contains a volume of blood product, such as packed red blood cells, that have hemolyzed less than 1% during at least 42 days storage in a non-extractable plastic storage bag containing a volume of hypotonic cell preservation solution.

  • Patent number: 5240829
    Abstract: A closed system for inactivating viruses in blood or blood components. The system includes at least one plastic bag which communicates with a separate container including a single viricidal substance or separate substances which, when mixed, provide in situgeneration of a viricidal substance. The viricidal substance can be transferred into the bag for subsequent viricidal use on blood components or for use on components in the bag. A preferred system provides a means for the in-situ generation of ClO.sub.2 from sterilizable, separate substances for viricidal use on blood or blood components.

  • Patent number: 4994057
    Abstract: An improved heat sterilizable blood bag system adapted for containing and mixing of different materials originally placed in separate but potentially communicating compartments. The improvement comprises of having a smaller squeezable compartment for one material attached to and capable of communicating with a larger compartment for the other material. The material in the smaller compartment is separated from the interior of the larger compartment by means of an externally manipulatable closure means which, when opened, permits mixture of the contents in the first compartment and contents of the second compartment when the smaller compartment is repeatedly squeezed.
