Abstract:
A scalable, low cost, reliable, compliant, low profile, low insertion force, high-density, separable and reconnectable connector for high speed, high performance electronic circuitry and semiconductors. The electrical connector can be used to make, for example, electrical connections from components such as a Printed Circuit Board (PCB) to another PCB, MPU, NPU, or other semiconductor device. A normalized working range for an array of elastic contacts of the interposer can be about 0.2 to 1.0. A reversible normalized working range is maintained through multiple connections and reconnections using a highly elastic material for the contact arms. In one aspect, a first electrical component having a first array pitch can be connected to a second electrical component having a second array pitch.

An electrical connector includes an electrical contact array (17) having a plurality of contact elements (15) where each contact element has at least one conductive, resilient spring portion.
Abstract:
The present invention provides a clamp with spring contact elements to receive and secure a flat flex cable with exposed electrical traces to an electrical circuit such as on a printed circuit board. The clamp of the present invention has features for enhanced registration and alignment of exposed electrical traces on the flat flex cable to the spring contact elements in the clamp. Another aspect of the invention is the ability to connect high density contact arrays within the clamp to a circuit board via an array of contact pads on the opposite side of the substrate on which the spring contact elements are disposed. One exemplary application of the present invention is to connect a camera module in a cell phone to a printed circuit board or like electrical device in the phone.
Abstract:
A compliant, scalable, thermal-electrical-mechanical, flexible electrical connector. In one configuration, the flexible electrical connector comprises a flexible substrate, a first and second conductive layer, and a plating contiguously applied over the conductive layers and holes through the substrate. The first and second conductive layers are adhered to opposite sides of the flexible substrate and have a plurality of raised contact elements in registration with at least a subset of the holes. At least some contact elements on the first and second conductive layers that oppose each other are in electrical communication with one another by way of the plating.
Abstract:
A connector, and method for forming same, for electrically connecting to pads formed on a semiconductor device includes a substrate and an array of contact elements of conductive material formed on the substrate. Each contact element includes a base portion attached to the top surface of the substrate and a curved spring portion extending from the base portion and having a distal end projecting above the substrate. The curved spring portion is formed to curve away from a plane of contact and has a curvature disposed to provide a controlled wiping action when engaging a respective pad of the semiconductor device.
Abstract:
Organic compounds showing the ability to inhibit effector toxin secretion or translocation mediated by bacterial type III secretion systems are disclosed. The disclosed type III secretion system inhibitor compounds are useful for combating infections by Gram-negative bacteria such as Salmonella spp., Shigella flexneri, Pseudomonas spp., Yersinia spp., enteropathogenic and enteroinvasive Escherichia coli, and Chlamydia spp. having such type III secretion systems.
Abstract:
An electrical connector includes an electrical contact array having a plurality of contact elements. Each contact element has at least one conductive, resilient spring portion formed in a conductive, resilient sheet, each spring portion being biased outwardly from the sheet. The electrical contact array is arranged in a predetermined pattern corresponding to an electrical device to be connected. The conductive sheet is bonded to a first surface of a dielectric substrate, each spring portion extending outwardly away from the dielectric substrate. The spring portions are electrically connected to conductors that are at least one of embedded in or extending through the dielectric substrate. At least some of the plurality of contact elements are singulated from one another on the dielectric substrate by a chemical etchant.
Abstract:
The invention provides fungicide and/or antifungal organic compounds and compositions thereof that kill or inhibit growth of cells of one or more microbial pathogens, such as pathogenic fungi species (including opportunistic pathogenic species) by administration to an individual (human or other mammal), plant, or foodstuff that is susceptible to infection by or has been infected with cells of the fungal species.
Abstract:
Organic compounds showing the ability to inhibit viral glycoprotein (GP)-mediated entry of a filovirus into a host cell are disclosed. The disclosed filovirus entry inhibitor compounds are useful for treating, preventing, or reducing the spread of infections by filovirus including the type species Marburg virus (MARV) and Ebola virus (EBOV). Preferred inhibitors of the invention provide therapeutic agents for combating the Ivory Coast, Sudan, Zaire, Bundibugyo, and Reston Ebola virus strains.
