    Abstract: An inductive power transfer system (1) comprises a primary unit (10) operable to generate an electromagnetic field and at least one secondary device (30), separable from the primary unit, and adapted to couple with the field when the secondary device is in proximity to the primary unit so that power can be received inductively by the secondary device from the primary unit without direct electrical conductive contacts therebetween. The system detects if there is a substantial difference between, on the one hand, a power drawn from the primary unit and, on the other hand, a power required by the secondary device or, if there is more than one secondary device, a combined power required by the secondary devices. Following such detection, the system restricts or stops the inductive power supply from the primary unit. Such a system can detect the presence of unwanted parasitic loads in the vicinity of the primary unit reliably.

    Abstract: Disclosed is a system and method for detecting the position of a wafer with respect to a calibrated reference position. In one embodiment of the invention, sensors are used to detect the edges of the wafer as the wafer is being passed over the sensors. This wafer detection information is then used to calculate the amount by which the wafer is off-centered such that corrections can be made before the wafer is placed onto a destination location.

    Abstract: A removable cap for receiving a writing implement includes a hollow tubular member with a closing wall at one end and an opening at the other end. The closing wall possesses three radial rib members and a central interior land portion which define three arcuately shaped apertures which are configured to allow air to communicate with the interior of the cap to dry residual ink on the writing point of the implement.

    Abstract: An inductive power transfer system comprises a primary unit, having a primary coil and an electrical drive unit which applies electrical drive signals to the primary coil so as to generate an electromagnetic field. The system also comprises at least one secondary device, separable from the primary unit and having a secondary coil which couples with the field when the secondary device is in proximity to the primary unit. A control unit causes a circuit including said primary coil to operate, during a measurement period, in an undriven resonating condition. In this condition the application of the drive signals to the primary coil by the electrical drive unit is suspended so that energy stored in the circuit decays over the course of the period. A decay measurement unit takes one or more measures of such energy decay during the measurement period. In dependence upon said one or more energy decay measures, the control unit controls the electrical drive unit so as to restrict or stop inductive power transfer from the primary unit.
