A finger-placement sensor tape aligns and removably secures a finger to a sensor pad of a reusable finger-clip optical sensor so as to assure the finger is repeatably aligned between the sensors emitters and detectors and that the finger stays aligned during a test procedure. The sensor tape has a double-sided tape layer having a silicon-based adhesive on a finger side and an acrylic adhesive on a sensor-side. An aperture is defined in the tape layer so as to allow emitters disposed in a top sensor pad to emit light through the tape layer to detectors disposed in a bottom sensor pad. A finger-side release layer is removably disposed over the silicon-based adhesive. A sensor-side release layer is removably disposed over the acrylic adhesive.

Chemical Resistant Glove Having Cut Resistant Properties
InactiveUS20090077713A1Low shear strengthReduces cut stress intensityGlovesThin material handlingLatex gloveChemical treatment
A cut resistant chemical handling glove that is flexible and lightweight comprises a cured, liquid-impervious polymeric latex shell. A tacky acrylic adhesive with low shear strength can be used. A cut resistant liner is slipped on the tacky adhesive coating and is infiltrated with a polymeric latex coating and cured to integrally attach the cut resistant liner with the cured polymeric coating. When the latex glove is worn on a hand and a cutting edge, such as a knife edge, contacts the glove, a crease is formed due to slip at the tacky adhesive-cut resistant liner interface creating a geometry that reduces cut stress intensity at the knife-edge thereby increasing the cut resistance of the glove. Processes for making and using these gloves are also described.
