Filed:

May 11, 1977

Appl. No.:

5/796034

Inventors:

Joseph M. Carter - Stafford TX

International Classification:

A01K 2900

US Classification:

119 1

Abstract:

An improved sanitary facility for pets is provided for the collecting, removing and disposing of small animal excrement without the attendant mess and odor heretofore experienced. A rotatable chamber which contains pet litter, sand or other suitable material, has a first closeable opening for animal ingress and egress, and a second opening for expulsion of separated waste. Filter means, disposed circumferentially within the chamber, selectively separate solid excrement and agglomerated matter from unsoiled litter as the chamber is rotated. The separated waste is continuously urged, by the combined action of gravity and the incline of the filter means, toward a second sealable opening in the chamber. The separated matter is expelled from the chamber through the second opening and deposited in an appropriate receptacle. Means are provided to prevent rotation of the chamber during use by the animal.

Abstract:

Certain implementations of the disclosed technology may include systems and methods for extending a frequency response of a transducer. A method is provided that can include receiving a measurement signal from a transducer, wherein the measurement signal includes distortion due to a resonant frequency of the transducer. The method includes applying a complementary filter to the measurement signal to produce a compensated signal, wherein applying the complementary filter reduces the distortion to less than about +/−1 dB for frequencies ranging from about zero to about 60% or greater of the resonant frequency. The method further includes outputting the compensated signal.
