Abstract: A razor blade including: a substrate having a tip portion including a tip region, a blade body including a base, and first and second outer sides disposed opposite a split line of the substrate that converge at a tip; and first and second coatings disposed substantially on the first and second outer sides, respectively. Also provided is a method of coating the razor blade, including: applying a first coating to at least a portion of the first outer side; and applying a second coating to at least a portion of the second outer side. The first and second coatings each extend from the tip region toward the base and are substantially different, as compared to each other. One or both of the first and second coatings comprise a plurality of layers of material.

Abstract: A novel cutting-edge structure and method and apparatus for manufacturing the cutting-edge structure is provided. The cutting-edge structure is comprised of naturally derived or renewable material at greater than 50% by volume fraction. In one embodiment, the naturally derived material is a cellulose nanostructure such as a cellulose nanocrystal. The cellulose nanocrystal is processed using a base or mold structure to provide a cutting edge of any shape such as linear or circular edge structures. The process includes dual cure steps to produce an optimal cutting-edge structure without shrinkage. The formed cutting-edge structure can be utilized as a razor blade as it is formed with very sharp tip and edge suitable for cutting hair. The base structure can form one or more cutting-edge structures simultaneously.

Abstract: A digital imaging method of analyzing pixel data of an image of a user's body for determining a user-specific hair removal efficiency value after removing hair is disclosed. The digital imaging method includes: aggregating training images of respective individuals' bodies after removing hair; training, using the pixel data of the training images, a hair removal efficiency model to determine hair removal efficiency values associated with a degree of hair removal efficiencies ranging from a least efficient to a most efficient; receiving an image of a user's body after removing hair; analyzing by the user image using the hair removal efficiency model to determine a user-specific hair removal efficiency value; generating a user-specific electronic recommendation designed to address a feature identifiable within the pixel data of the user's body based on the user-specific hair removal efficiency value; and rendering the recommendation on a display screen of a user computing device.

Abstract: A stand for a shaving razor handle with a cover having a top surface defining an opening with a lower cavity in communication with the top surface. The lower cavity having a handle resting surface with a second width configured to support a handle. A base mounted to the cover with a bottom surface opposite the top surface. The bottom surface defining a drainage opening extending into the lower cavity. A ring fixed to the bottom surface. The ring defines a slot extending from an outer edge of the ring to an inner edge of the ring.

Abstract: Digital imaging systems and methods are described for determining a user-specific skin irritation value of a user's skin after removing hair. An example method may be performed by one or more processors and may include aggregating training images comprising pixel data of skin of individuals after removing hair. A skin irritation model may be trained using the training images to output skin irritation values associated with a degree of skin irritation from least to most irritation. The method may include receiving an image of a user including pixel data of the user's skin after hair is removed from the skin, analyzing the image using the skin irritation model to determine a user-specific skin irritation value, generating a user-specific recommendation designed to address a feature identifiable within the pixel data of the user's skin, and rendering the recommendation on a display screen of a user computing device.

Abstract: A shaving razor cartridge with a housing having a top surface and a bottom surface. A guard is at the front of the housing. A cap is at a rear of the housing. At least one blade is mounted to the housing between the guard and the cap. The housing has a wall defining an opening extending from the top surface to the bottom surface that is configured to receive a portion of a handle. The wall having a pair of arms each with a distal end extending toward each other defining a gap. The bridge is a thermo-plastic elastomer that is different than a polymeric material of the housing.

Abstract: A link conveyor for an assembly machine and methods for chordal compensation in a link conveyor, may include a first upper chordal compensation cam in the upper rail assembly at the first end of the frame to deflect the chain by a first upper variable deflection amount; a first lower chordal compensation cam in the lower rail assembly at the first end of the frame to deflect the chain by a first lower variable deflection amount; and configuring the first upper variable deflection amount and the first lower variable deflection amount to reduce deviation between a first velocity of the chain at the first end of the frame and a second velocity of the chain at the second end of the frame.

Abstract: A consumer appliance with a body. A cartridge removably mounted to the body. The cartridge having a surface with a first colored region and a second colored region. A control circuit positioned within the body. A first emitter positioned on the body that projects a light at the first colored region. A second emitter positioned on the body that projects light at the second colored region. A first light sensor positioned on the body that sends a first signal to the control circuit based on a color of light reflected from the first colored region.
