Abstract: A shaving razor system with a handle and a shaving cartridge mounted to the handle. A circuit board having an electrical switch in communication with a power source is positioned within the handle. A heating element is in electrical communication with the electrical switch. The heating element having a skin contacting surface. The heating element has a first pre-determined temperature and a second pre-determined temperature. The second predetermined temperature is at least two degrees Celsius different from the first pre-determined temperature.

Abstract: An illumination level of a luminous element of a user interface for an electrical device is controlled by a processor driving the luminous element with a pulse-width-modulated (PWM) or other type of control signal that is calculated based on a) a signal corresponding to a desired time-varying illumination level of the luminous element to be perceived by a human observer and b) a nonlinear sensitivity relationship between an actual illumination level and a resulting illumination level perceived by a human eye, wherein the corresponding signal comprises an increasing sinusoidal-based ramp function and a decreasing sinusoidal-based ramp function.

Abstract: A monitoring device for monitoring a user's cleaning activity, comprising a squeezable housing and a sensor housed within the housing, wherein the sensor is configured to sense at least pressure exerted to the monitoring device by the user during the cleaning activity.

Abstract: A method and apparatus for automatically leveling a band of fibers such as sliver, roving and the like by varying the drafting speed of a drafting mechanism responsive to variations in the thickness of the band. Analogue signals are produced by variations in the thickness of the band and are converted to digital signals for being stored in a digital register. After a period of time, corresponding with the time for conveyance of the scanned point in the sliver up to and into the draft zone, the information is read out of the storage register and converted back to an analogue signal. The analogue signal is compared with another signal representing the actual drafting speed for producing a compared signal for controlling the drafting speed.

Abstract: One end of the housing for a spinning turbine is closed by a cover adjacent to the spinning cup mouth, which cover is connected with sliver-supply and yarn drawoff apparatus. The other housing end portion encircles a sleeve having bearings for the spinning cup shaft. Such shaft may be connected to drive means such as a belt or a commutatorless direct current motor, which drive means can be quickly disconnected. The sleeve-encircling housing portion includes quickly-releasable means for releasing the bearing sleeve for removal either alone or with attached drive means, and for replacement by a substitute bearing unit. The housing may have a longitudinal slit through a portion of its wall and cooperating lugs on each side of the slit for receiving nut and bolt means to clamp the split housing around the bearing sleeve. Alternatively, a set screw extends through the housing wall and bears on the sleeve to prevent sleeve movement.

Abstract: Free flight magnetizable selector elements are transferable from a selector element store disc to a selector element support disc for selecting particular ones of a series of textile processing implements in response to a program. The discs are disposed with an arcuate portion of one disc closely adjacent to an arcuate portion of the other disc, and the selector elements are transferred from store disc sockets to support disc sockets and vice versa by a transfer magnet. The discs include magnets with opposite polarity to maintain transferred selector elements in the sockets of the selected disc until the transfer magnet effects another transfer. The sockets of the store means and support means have the same pitch as the textile implements; however, the sockets of the entire support means may be distributed among a set of identical superjacent discs each having a socket pitch an integer multiple of the textile processing implement pitch. The store means has a corresponding set of superjacent discs.
