Abstract: A process for cleansing microorganisms from the pliant epidermal surface of a human hand which comprises brushlessly scrubbing the pliant epidermal surface of the human hand with a plurality of cleansing fluids. The cleansing fluids are oscillating sprays which are sprayed onto the epidermal surface at a frequency of 20-80 HZ and at a temperature of 40-50° C. thereby removing microorganisms present on the pliant epidermal surface.

Abstract: Fluidic oscillators are used to apply pulsatile sweeping streams of a liquid, preferably a cleansing solution, to selected areas of epidermis in a manner consistent with the resonant characteristics of the epidermis. The device thereby cleanses the skin, pores, and folds of microorganisms.

Abstract: An animal birth detector is described comprising apparatus attached in the proximity of the animal's vulva for detecting the birth of the animal fetus by monitoring the size of the vulva during the period prior to and during delivery of the fetus. More specifically, the animal birth detector comprises a transmitter attached to the skin proximate one side of the animal's vulva, the transmitter utilizing a reed relay switch to sense the proximity of a permanent magnet located on the opposite side of the vulva. As the vulva dilates at time of delivery of the animal fetus, the magnet is moved out of the magnetic field sensing area of the reed switch, turning on the transmitter whose transmissions are received by a receiver monitored by the stockman. The transmitter and magnet are held in place on the animal's rear section by an adhesive coated or sutured vinyl holding pad.
