Abstract: The invention relates to apparatus for generating electrical signals representing the instantaneous position and attitude of an object with reference to a coordinate system. A pair of wave transmitters are mounted and controlled so that they follow any movement of the object and are arranged to transmit ultrasonic pulses to three planar transducers arranged to convert the received energy into signals representative of the instantaneous position and attitude of the two transmitters relative to the three transducers. The invention is particularly applicable to apparatus for the ultrasonic examination of bodies having non-planar surfaces and in this case the object referred to is the ultrasonic probe designed to transmit wave energy into the body. The probe may be mounted with one or two degrees of rotational freedom on a boom which is itself mounted with at least two degrees of rotational freedom on a vertical column.

Abstract: There are means in the sanitary facility defining a receiving bowl for liquid and/or solid excrement, and the bowl has a discharge valve in the bottom portion thereof. Also, there are means for controlling flow through the valve, including a pivotally mounted water receptacle which is operative to open the valve to flow when the receptacle is relatively inclined about its pivotal axis in a first position, and to close the valve to flow when the receptacle is relatively inclined about its pivotal axis in a second position relatively angularly spaced from the first position. Additionally, there are means for supplying water to the bowl to form a pool of carrier liquid therein when the valve is closed; a control valve which is adapted to be interconnected to a source of pressurized water; and control means which are responsive to the level of water in the bowl to close and open the control valve to flow as the water level rises and falls, respectively.
