Abstract: Various implementations include in-ear wearable audio devices. In certain implementations, the in-ear audio devices include an eartip with a body having first and second ends, an inner wall extending between the first and second ends defining a hollow passage to conduct acoustic energy, and a deformable outer wall connected to the inner wall of the body at the first end and tapering away from the inner wall toward the second end, where the deformable outer wall is functionally graded from the first end to the second end to comply with an entrance of an ear canal of a user. In additional implementations, the eartip includes a retaining structure, and at least one of the inner wall or the outer wall of the body, or the retaining structure, has an integral electronic component and/or an electronic component signal trace.

Abstract: A headphone cushion includes a body formed of a partially reticulated polymeric foam and including a front surface configured to engage or surround an ear or head of a user, side surfaces, and a rear surface. The headphone cushion further includes a layer of high-density polymer material extending over at least a portion of the body.

Abstract: An earphone cushion includes a body formed of a partially reticulated polymeric foam and including a front surface configured to engage or surround the ear of a user, and a rear surface, a snap ring at least partially embedded in and integrally formed with the body and including a periphery configured to engage one or more retention elements of an earcup of a headphone, and a non-porous film on the front surface of the body.

Abstract: A method of fabricating a wearable device having one or more integrated electronic components, including providing a substrate having an elastomeric material, at least one metal additive, and/or a carbon source additive; forming electrical circuitry within the elastomeric material by structuring one or more electrically conductive traces and plating the one or more electrically conductive traces; and providing the electrical circuitry with a sensor, wherein the sensor is configured to come in direct contact with skin of an individual.

Abstract: An induction cooking utensil is constructed such that it cooks food within its chamber while maintaining a relatively cool outer surface (e.g., preferably an outer surface that is cool enough to pick up with one's bare hands). The cooking utensil includes an inner wall that is made at least in part of an electrically conductive material and an outer wall that is made at least in part of the electrically non-conductive material. A reflective layer, a vacuum-sealed thermal insulator and/or a gas more resistant to conducting heat than air is disposed between the inner and outer walls to resist the transfer of heat from the inner wall to the outer wall.

Abstract: An induction cooking system with an induction heating system, a cooktop, and cool touch cookware that has a target layer that is heated by induction. An absolute cookware temperature is directly sensed at one or more locations of the cookware. A relative cookware temperature can be determined based on the value of an electrical variable of a circuit that includes the target layer. The cookware can include a layer of thermal insulation directly below and spaced from the target layer by a gap. The insulation and gap act as the major heat insulating elements to keep the outer surface of the cookware cool. The cooktop can be cooled by placing a cooling chamber just below the cooktop and drawing air through the cooling chamber. The induction coil can be located in the cooling chamber.

Abstract: An apparatus for a cooking system with a number of electrically-operated heating elements that each define a center, and a number of heating element power control circuits that each control power flow to a respective one of the heating elements. There is a cooktop surface member located above the heating elements and defining a top surface and a front edge. There are also a number of user interface elements visible from above the top surface of the cooktop surface member and spaced from the heating elements. One of each of the user interface elements is operatively associated with a respective one of the heating elements and used to control the heating element power control circuit for such heating element.

Abstract: An induction cooking system including one or more methods or apparatus for identifying items of cookware. The identifying may include identifying whether in use, the temperature of the outside surface of the element of cookware is significantly lower than the temperature of the inside surface. The methods may include one or more of measuring impedance, communicating information by RF radiation, or measuring reactance.

Abstract: Among other things, light that carries information about cooking is directed in a first direction towards a redirection element and, at the redirection element, the light is redirected to be visible to a person cooking.

Abstract: An induction cooking utensil is constructed to have an inner wall that is made at least in part of electrically conductive material and an outer wall having a bottom portion and a sidewall portion. The bottom portion is made at least in part of a non-conductive material (e.g., so as to not interfere substantially with the magnetic field produced by the induction cooktop) and the sidewall portion is made at least in part of a metallic material.

Abstract: An induction cooking utensil includes an inner wall and an outer wall that is separated by a vacuumed-gap. Disposed within the vacuumed-gap is a piece of getter material that absorbs at least some gas present within the gap. The getter material may thus be used to create and/or preserve the vacuum.
