Abstract: Disclosed are wearable ultrasound probes for use in trauma triage and assessment. The probes define a finger-receiving aperture and include an ultrasound array disposed adjacent the distal end wherein the ultrasound array is angled toward the bottom side of the probe about 10-50 degrees from the longitudinal axis and a second ultrasound array adjacent the distal end and proximal to the first ultrasound array, wherein the second ultrasound array is angled about 105-155 degrees from the first ultrasound array.

Abstract: Disclosed is a process capable of precision slicing substrates with a dimension in the linear direction of at least I meter, comprising the following steps: (I) affixing the work piece to a stage; (11) providing multiple essentially parallel, essentially straight wires having a diameter in the range from about 100 ?m to about 600 ?m, and allowing the multiple wires to contact the surface of the work piece; (III) allowing the multiple wires to travel in linear directions, optionally with cutting slurry dispensed thereon; and (IV) allowing the multiple wires to move in the slicing directions relative to the work piece; wherein in step (IV), the multiple wires maintain essentially straight and essentially parallel to each other. The process can be used for slicing silica glass substrates having a diameter large than 2 meters in producing slices thereof with a high surface flatness and a low thickness variation.
