Abstract: An apparatus for raising and lowering toilet seating parts, such as a toilet seat or a seat cover or lid, can be placed on a toilet. A lifting means, such as a bar or lever, connects to the toilet seating part. The lifting means is mounted on a beam, and as the beam rotates, so does the lifting means. A placing means, such as an anchor or clip, holds the apparatus in place. A handle is attached to the beam to rotate the beam and lift or lower the toilet seating part.

Abstract: The present invention is related to a method of artificial animal reproduction by which healthy cows and heifers are impregnated on the first attempt at artificial insemination. The sperm is deposited at the time the uterine horns are at the optimum time to conceive.

Abstract: The bio-informatics system of the present invention serves to identify by electronic means, in body fluids of domestic and/or wild mammals, the metabolic changes that occur in each of the physiological moments of economic, scientific, and technological importance, associated with the female reproduction and with the health of animals in general. The system encrypts the information, analyzes it, memorizes when each one of the metabolic variables reach a predetermined level, and informs a receiver of the event.

Abstract: A method to palpate cows or heifers which includes determining the natural state of consistency of the uterus to determine the size of the uterus to know the physio-reproductive status of the uterus, touching the uterus by sliding the hand on the uterus from the base of the horns towards the tip of the horns to determine the anatomically similarities or differences between the two horns to determine which of the horns is active; and feel the uterus to determine how the active horn reacts.

Abstract: The present invention relates to an embryos collector system used for the collection and careful selection of embryos, which maintains the fluid control from the uterus discharge fluids inside the collector device and the control of displacement of the embryos and mucosal in the interior of the device. This system includes a conduit system free of internal collision points where the embryos can safely navigate to a section on the device, in which the direction, force, and speed of the turbulent currents are controlled; thus, the embryos are not subjected to any trauma, cannot be trapped by the mucosal; nor dragged by the filtration mesh.
