摘要:
Apparatus for automatically adjusting the orientation of a first surface of a first body to be against a second surface of a second body when said first surface is pressed against said second surface. The apparatus includes a means for movably mounting the first body to a support which permits rotation of the first surface so that when the first surface is pressed against the second surface, the first surface rotates with respect to the support resulting in the first surface being against the second surface.

A method is described for aligning a contact pattern on an electronic device held by a first movable support, with a bond site pattern on a lead frame held by a second movable support. The method includes the steps of: (a) creating and storing models of a chip's contact pattern and a lead frame's bond site pattern; (b) imaging the electronic device and lead frame; (c) determining the position of contacts on said electronic device and reorienting the contact pattern model to a best fit with the imaged contact position; (d) determining the position of each bond site on the imaged lead frame and reorienting the bond site model to a best fit with the imaged bond site position; (e) determining positional differences between the reoriented lead frame and contact pattern models; and (f) generating signals to reorient the first and second movable supports to minimize the positional differences when they are moved into a bonding positon. A machine is described for performing the above method wherein each of three main movable elements of the machine is assigned a dimensional axis in which its travel is non-adjustable, so that other movable elements can be calibrated thereagainst.

The susceptibility of human macrophages to human immunodeficiency virus (HIV) infection depends on cell surface expression of the human CD4 molecule and CC cytokine receptor 5. CCR5 is a member of the 7-transmembrane segment superfamily of G-protein-coupled cell surface molecules. CCR5 plays an essential role in the membrane fusion step of infection by some HIV isolates. The establishment of stable, nonhuman cell lines and transgenic mammals having cells that coexpress human CD4 and CCR5 provides valuable tools for the continuing research of HIV infection. In addition, antibodies which bind to CCR5, CCR5 variants, and CCR5-binding agents, capable of blocking membrane fusion between HIV and target cells represent potential anti-HIV therapeutics for macrophage-tropic strains of HIV.
摘要:
A novel radio frequency transponder (tag) with a minimum of components and connects is thin and flexible because these components and connects can be unsupported by a substrate layer. This is accomplished by using a conducting leadframe structure not only as a connection medium but also as a circuit element, i.e., the transponder antenna. In various preferred embodiments, the leadframe is mechanically positioned and fixably attached to a circuit chip so that the leadframe (antenna) is self supporting. A protective coating can be added where the leadframe is attached to the circuit chip. Further a protective surrounding can envelops the entire leadframe antenna, circuit chip, and, if provided, the protective coating.
摘要:
A computer system that includes a plurality of servers, and a shared I/O subsystem coupled to each of the servers and to one or more I/O interfaces. The shared I/O subsystem services I/O requests made by two or more of the servers. Each I/O interface may couple to a network, appliance, or other device. The I/O requests serviced by the shared I/O subsystem may alternatively include software initiated or hardware initiated I/O requests. Different servers coupled to the shared I/O subsystem may use different operating systems, and each I/O interface may be used by two or more servers.

摘要:
The present invention relates to the discovery of molecules that inhibit viral infection and promote a host immune response to a pathogen. More specifically, the invention disclosed herein concerns molecules that interact with a FPR class receptor, inhibit HIV infection, and stimulate an inflammatory response in a subject. Embodiments of the invention include biotechnological tools, prophylactics, therapeutics, and methods of use of the foregoing, for the study, treatment, and prevention of HIV infection and the induction of an inflammatory response in a subject.
