Abstract: The present invention relates to a shaving device includes a housing with a skin contacting surface and at least one cutting blade mounted in the housing, wherein the cutting blade has an asymmetric cross-sectional shape with a first face, a second face opposed to the first face and a cutting edge at the intersection of the first face and the second face. An intersecting line connects the primary bevel of the first face and the secondary bevel of the second face such that a first wedge angle q1 and a second wedge angle q2 are formed. Further, the clearance angle ? between the skin contacting surface and the primary bevel of the first surface is ?11°, the effective cutting angle ? between the skin contacting surface and the bisecting line of the first wedge angle q1 is ?10° and q1>q2.

Abstract: Methods of the present disclosure can include: using a computing device to perform actions including: applying a design rule check (DRC) on a proposed integrated circuit (IC) layout, wherein the DRC applies a set of restrictive design rules (RDRs) in response to the proposed IC layout being a contact area (CA) layout; computing a conflict graph for the proposed IC layout in response to one of the IC layout being a metal layer layout and the set of RDRs being satisfied; determining whether the IC layout is one of non-colorable, indeterminate, partially colorable, and fully colorable; and partially coloring the IC layout and identifying non-colorable nodes in response to the IC layout being indeterminate or partially colorable.
