A sensor apparatus includes: a display cover including an operation area that is pressed by an operator and a circumferential area located on the circumference of the operation area; a frame including an opening covered by the operation area and a fixing portion that fixes the circumferential area; a touch panel that is supported by the display cover to be positioned at the opening and detects a position at which the operator comes into contact with the operation area; and a pressure-sensitive sensor that is provided between the display cover and the frame, includes a first electrode and a second electrode opposed to the first electrode, and detects a pressing force with respect to the operation area based on a change of a capacitance between the first electrode and the second electrode that corresponds to a deflection amount of the display cover.

Sensor apparatus and electronic apparatus

A power supply apparatus and method are provided. A conversion component outputs a first current having a predetermined phase region, an output component outputs a load voltage, a sense component senses a second current value, and a switch element allows current to flow in a first state and impedes current in a second state. The switch element changes between states based on a drive signal forcing the switch into the second state when the first current is in the predetermined phase region and the second current value exceeds a threshold indicating an overcurrent condition. A region determination circuit determines whether the first current is in the predetermined phase region and produces a phase region signal. An overcurrent detection circuit senses the second current value, determines whether it exceeds an overcurrent condition threshold, and produces an overcurrent signal. A protection circuit causes the drive circuit to switch the drive signal.

Power supply apparatus and method

The present invention provides a multi-output DC-DC converter which supplies an input direct voltage to a series circuit consisting of a primary winding () of a transformer () and a switching circuit () to obtain first and second output direct voltages from a secondary winding () of the transformer () via first and second rectifying circuits, wherein a switching signal of the switching circuit () is controlled corresponding to the first output direct voltage so that the first output direct voltage is caused to be constant, and a variable reactor () is inserted into the second rectifying circuit. Thus, loss of power can be reduced in a simplified configuration.
