Abstract: A device for cracking open an egg is shown, having egg-size sensing means for determining the size of an egg positioned in the device, thereby providing for automatic calibration of the device to the specific size of an egg to be cracked. The calibration determines how much would the distance between the piercing members and the imaginary longitudinal axis of the egg be reduced before the piercing members stop their advancing towards the egg and start moving apart for cracking its shell open. The device can thus open eggs of different sizes, e.g. having widths between 40 and 50 millimeters, accurately without requiring special preparation or manual calibration. A method for cracking open an egg based on said device is also shown.

Abstract: Excrement catching device for a quadruped is disclosed, comprising a harness and a receptacle-holder connected to the harness, wherein the connection between the harness and the receptacle holder is configured to respond to the gravitational force acting on the receptacle-holder by allowing movement of the receptacle-holder between a loosen neutral position when the quadruped stands or walks and an excrement-catching position when the quadruped pose being its customary position to defecate. Excrement catching method is disclosed accordingly, comprising configuring a device to be responsive to gravitational force by taking an operative position for catching excrement automatically when the quadruped takes a particular pose.
