  • Publication number: 20060110282
    Abstract: The connection, assembly, or fill of two or more pre-sterilized components having at least one terminal end each for attachment to another component, and an apparatus for performing such a connection, while maintaining the sterility of the components is disclosed. The resulting connection is made permanent by bonding the contacting components together using either a solvent bonding technique, a radio frequency sealer, a heat sealer, or any other suitable process. The connection is preferably made within an active sterile field. Using a low-voltage electron beam instrument, such as the MIN-EB™, a suitable sterile field sphere can be created. The terminal ends of the multiple components remain within the sterile field sphere until the possibility of contamination within the sealed components is significantly reduced to industry acceptable standards.

  • Publication number: 20060007878
    Abstract: An apparatus and method for switching a mobile processing device from communicating over a wireless connection with a first base unit to a second base unit based upon latency. In accordance with this invention, the mobile processing device determines latency information for packets being transmitted over the wireless connection to and from a base unit. The latency information is compared to a threshold value. If the latency information is greater than the threshold value, the mobile processing device adjusts parameters of the wireless connection between the mobile processing device and the network.

  • Publication number: 20050060319
    Abstract: A technique for network planning that includes an interface for guiding a network user through the network allocation process, such as defining groups of clients based on their capabilities. Portions of the wireless local area network infrastructure, e.g., access points, are allocated among the groups. When a client attempts to associate with an access point, the access point determines the client capabilities. If the client is supported by the access point, the access point allows the client to associate and sends the client a message that contains a prioritized list of other nearby access points allocated to service that client, otherwise the access point sends a prioritized roaming list of nearby access points to the client that are allocated to serve that type of client. Feedback is provided by the network infrastructure enabling a network user or the network to automatically reallocate resources based on the feedback.

  • Patent number: 6358236
    Abstract: A device is provided for reconstituting a lyophilized or powdered medicament such as blood factor VIII which must be reconstituted just prior to use, such as by introduction of a sterile fluid from a syringe, which comprises a housing having an upper section capable of receiving a syringe and a lower section capable of receiving a vial containing the medicament in co-axial alignment with the syringe, a middle section connecting the upper and lower sections which has a central aperture which forms a passageway for fluid transfer between the syringe and the vial, and a hollow vented spike which extends downwardly from the central aperture for a length sufficient to ensure that the lower end of the spike will pierce the seal and enter the interior of a vial housed in the lower section of the device. The invention is advantageous because the vented opening in the spike will allow for an equalization of the pressure after the piercing of the vial by the spike which will facilitate the use of the device.
