Abstract: An electrochemical cell is described. The electrochemical cell includes an anode, a cathode, a separator between said anode and said cathode, and an electrolyte. The electrolyte includes a salt dissolved in an organic solvent. The separator in combination with the electrolyte has an area specific resistance less than 2 ohm-cm2. The electrochemical cell has an interfacial anode to cathode ratio of less than about 1.1.

Abstract: A razor cartridge comprising a housing, a guard disposed toward a front portion of the housing, a cap disposed toward a rear portion of the housing, a plurality of bent blade assemblies, wherein at least one of the blade assemblies comprises one or more perforations along a length of the assembly. In another embodiment, a razor cartridge comprising a housing, a guard disposed toward a front portion of the housing, a cap disposed toward a rear portion of the housing, a plurality of integrally formed bent blade assemblies, wherein each of the blade assemblies comprises one or more perforations along a length of the assembly.

Abstract: A system and method for generating a numerical skin model. The skin model may be used to predict the interaction of the skin to various devices, such as shaving devices and absorbent articles, for example. The computer-based numerical skin material model of the simulated skin may comprise a mechanical behavior model of a surface epidermis, a mechanical behavior model of a dermis, a mechanical behavior model of a hypodermis, and a van der Waals hyperelastic formulation to represent the behavior of the simulated skin. A strain stiffening viscoelasticty of the simulated human skin may be determined by a Prony time series expansion.

Abstract: A primary battery includes a cathode having a non-stoichiometric metal oxide including transition metals Ni, Mn, Co, or a combination of metal atoms, an alkali metal, and hydrogen; an anode; a separator between the cathode and the anode; and an alkaline electrolyte.

Abstract: A battery includes a separator with a trapping layer that traps dissolved metal ions.

Abstract: A shaving blade unit includes a housing having a front edge, a rear edge and side edges extending between the front and rear edges. The housing has an aperture located between the front and rear edges. One or more shaving blades are positioned between the front edge and the rear edge and the one or more blades have cutting edges arranged to define a first cutting region. A clip is arranged to retain the one or more shaving blades on the housing. The clip has a leg received by the aperture, the leg having a bent portion defining a curvature to secure the clip to the housing.

Abstract: A shaving blade unit comprising a shaving cartridge having a floatably secured shaving blade member wherein said cartridge comprises: a) a housing with a front wall, a rear wall, and opposing side walls extending between said front and rear walls; b) said shaving blade member having opposing ends with a shoulder at each end and wherein said shoulder rests along said side wall and wherein a cutting edge of said shaving blade member is facing a front surface of said housing; c) a resilient member disposed rearward of said shaving blade member and that is secured by a shaving blade member retainer; and wherein said resilient member provides a forward biasing force to said shaving blade member such that said contact between said shoulder and said side wall is at least maintained when said unit is removed from a skin surface during shaving.

Abstract: A wet shaving razor cartridge that comprises a plurality of at least five elongate blade assemblies disposed in parallel between a guard and a cap of a housing, each blade assembly having a sharp cutting edge; wherein said blade assemblies exhibit a cumulative interblade span of no greater than about 3 mm. Also, a wet shaving razor cartridge that comprise a plurality of at least four elongate blade assemblies disposed in parallel between a guard and a cap of a housing, each blade assembly having a sharp cutting edge; wherein said blade assemblies exhibit a cumulative interblade span of no greater than about 2.5 mm.
