Abstract: Apparatus for a digital averaging filter, particularly suited for use with an aeronautical navigation receiver, for reducing oscillatory deviation errors that appear in a course deviation voltage produced by the receiver and occur as the result of reflected incoming radio-navigation signals and/or interfering signals as described. In essence, this apparatus first amplifies, filters and repetitively samples the course deviation voltage to provide digital representations thereof. Each digital representation is then converted by a digital to pulse count converter into a series of pulses wherein the value of each digital representation is encoded into the number of pulses in the series. Thereafter, these pulses are totalized over a pre-defined interval. The resulting totalized count is then divided to produce an average value, which at the end of the pre-defined interval accurately reflects the average course deviation error.

Abstract: Apparatus is described for a cosmetic container that can be used for holding at least two differently colored cosmetic powders--such as colored blush, for mixing a pre-determined portion of each powder together within the container in order to yield a resulting cosmetic powder of a desired shade and for applying the resulting powder to a user's body.
