Abstract: An apparatus including a patient interface device formed from a flat substrate that is folded, wherein the patient interface device includes a plurality of seams where sections of the substrate are joined together, and wherein one or more of the plurality of seams form a shape that corresponds to a perimeter of a bottom side of a nose from a first alare corner of the nose to a tip of the nose to a second alare corner of the nose.

Abstract: Methods are disclosed for the detection of structural variations and/or repair events in chromosomes by labeling of single-stranded chromatids with probes, which in illustrative embodiments are of different colors. The hybridization pattern of the labeled probes produces a spectral pattern that provides high-resolution detection of structural variations and/or repair events, which for example can facilitate distinction of benign structural variations from deleterious structural variations. Further, the spectral pattern provides information regarding complex structural variations where more than one rearrangement of chromosomal segments may have occurred. Spectral information can be used to generate data tables upon which nodal analysis can be applied to identify structural features of interest.

Abstract: Method of determining electrical anisotropy in a subsurface formation, wherein electromagnetic field data from a multi-offset electromagnetic survey obtained by using an electromagnetic source and a plurality of electromagnetic receivers at varying offset distances from the source is provided. The electromagnetic field data comprises a first set of multi-offset response signals received at each receiver with the electromagnetic source emitting at a first frequency, and at least one additional set of multi-offset response signals received at each receiver with the electromagnetic source emitting at a different frequency. The presence of electrical anisotropy in the subsurface formation is determined using the first and at least one additional sets of multi-offset response signals.

Abstract: A commutator for rotation with or by the shaft of a electrical machine has first and second electrically conductive commutator segments provided on a base for electrical engagement with brushes connected to windings. Isolated from and interspersed between the commutator segments are first and second freewheeling segments. A first diode is connected between the first commutator segment and the first freewheeling segment. A second diode is connected between the second commutator segment and the second freewheeling segment. The diodes allow current to flow in only one direction between the commutator and freewheeling segments to help suppress commutation sparking.
