摘要： Various embodiments of an optical proximity sensor having a lead frame and no overlying metal shield are disclosed. In one embodiment, a light emitter and a light detector are mounted on a lead frame comprising a plurality of discrete electrically conductive elements having upper and lower surfaces, at least some of the elements not being electrically connected to one another. An integrated circuit is die-attached to an underside of the lead frame. An optically-transmissive infrared pass compound is molded over the light detector and the light emitter and portions of the lead frame. Next, an optically non-transmissive infrared cut compound is molded over the optically-transmissive infrared pass compound to provide an optical proximity sensor having no metal shield but exhibiting very low crosstalk characteristics.

摘要： Immunogenic compositions and methods for eliciting an immune response against S. epidermidis and other related staphylococci are provided. The immunogenic compositions can include immunogenic conjugates of poly-γ-glutamic acid (such as γDLPGA) polypeptides of S. epidermidis, or related staphylococci that express a γPGA polypeptide. The γPGA conjugates elicit an effective immune response against S. epidermidis, or other staphylococci, in subjects to which the conjugates are administered. A method of treating an infection caused by a Staphylococcus organism that expresses cap genes is also disclosed. The method can include selecting a subject who is at risk of or has been diagonosed with the infection by the Staphylococcus organism which expresses γPGA from the cap genes. Further, the expression of a γPGA polypeptide by the organism can then be altered.
