Abstract: A toilet bowl unit includes a toilet bowl with an inner toilet bowl surface having an upper peripheral portion, a central peripheral portion and a lower sump portion. A peripheral slot separates a lower edge of the upper peripheral portion from an upper edge of the central peripheral portion. A peripheral water channel is concealed inside the toilet bowl unit and has a side wall which is a weir over which water may flow into the peripheral slot. The slot has a discharge opening which is substantially horizontal at the rear and sides of the inner toilet bowl surface (for discharging a curtain of water) and includes at least one serpentine portion at the front of the inner toilet bowl surface (for discharging a jet of water). The horizontal portion(s) of the discharge opening are positioned just below a seat platform surface in order to minimize the unwashed area at the top of the inner toilet bowl surface.

Abstract: A detector for detecting a buried current carrying conductor includes a digital signal processor, magnetic sensors, and a power supply unit. The power supply unit is a switched mode power supply which incorporates a proportional integral differential controller feedback algorithm and which is managed by the digital signal processor. The load and source voltage are monitored by the digital signal processor and a look-up table is used to control a pulse width modulator, which drives a single ended primary induction controller. The digital signal processor processes and compares signals received from the sensors to calculate a depth of a buried conductor. The self-generated noise of the power supply unit does not interfere with the frequency bands of detection of the detector.

Abstract: A detector 1 for detecting a current carrying conductor determines the presence of a current carrying conductor one or more of passive or active modes. In the passive modes, the detector 1 detects either very low frequency radio signals re-radiated from a conductor or electromagnetic radiation produced by a conductor as a result of mains voltage carried in the conductor, or in a nearby conductor. In the active mode, an alternating signal from a dedicated signal generator is coupled into the buried conductor. Signals are induced in a pair of antennae 3, 5 in the detector 1, and the signals are processed in each of these modes simultaneously. The outputs of each of the modes are convolved to produce an audio and/or visual alert if a current carrying conductor is detected by any of these modes.

Abstract: A detector 1 for detecting a current carrying conductor has a pair of vertically spaced antennae 3, 5 to detect the magnetic radiation produced by a current carrying conductor as a result of one or both of the mains power supply or an electromagnetic signal which is induced in the conductor by a dedicated signal transmitter. The detector 1 continuously calculates the depth of a buried conductor and if the buried conductor is above a predetermined minimum depth then the detector 1 triggers an audio and/or visual alarm. By reducing the sensitivity of the antennae 3, 5, the lateral offset range for which the alarm sounds is reduced and the location of a buried conductor can be determined.
