  • Publication number: 20050124061
    Abstract: Hapten-carrier conjugates capable of eliciting anti-hapten antibodies in vivo by administering, in a therapeutic composition, are disclosed. Methods of preparing said conjugates and therapeutic compositions are also disclosed. Where the hapten is a drug of abuse, a therapeutic composition containing the hapten-carrier conjugate is particularly useful in the treatment of drug addiction, more particularly, cocaine addiction. Passive immunization using antibodies raised against conjugates of the instant invention is also disclosed. The therapeutic composition is suitable for co-therapy with other conventional drugs.

  • Publication number: 20050025067
    Abstract: The present invention extends to methods, systems, and computer program product for waking a link layer based on data included in a network packet. A sending computer system and a receiving computer system are connected to a common network, such as, for example, an IEEE 1394 network. A physical layer at the receiving computer system receives a network packet from the sending computer system. The physical layer parses a plurality of bytes of packet data contained in the received network packet. The receiving computer system compares at least a portion of the packet data to rule data in a physical layer rule register. Based on the results of the comparison, it is determined if the physical layer is to assert a link on signal that, when received at a corresponding link layer, wakes the corresponding link layer.

  • Patent number: 6724239
    Abstract: A voltage boost circuit includes a boost capacitor; a charge circuit for charging in the charging mode the boost capacitor to a supply voltage, the charging circuit including a charging MOS switch interconnected between the supply voltage and one terminal of the boost capacitor and a back gate isolation circuit connected to the back gate of the charging MOS switch and including a first switch for connecting the back gate to the supply voltage for reverse biasing the back gate in the charging mode and the second switch for connecting the back gate to the one terminal of the boost capacitor for reverse biasing the back gate in the boost mode to prevent charge loss from the boost capacitor; and a boost bias voltage and a boost switch for connecting the second terminal of the boost capacitor to the boost bias voltage in the boost mode.
