    摘要: A ground fault detection circuit includes: a first switch circuit that connects/disconnects a first path between a positive bus bar and a ground potential section, the positive bus bar being connected to positive electrodes of secondary battery units through a field-effect transistor including a parasitic diode; a second switch circuit that connects/disconnects a second path between a negative bus bar and a ground potential section, the negative bus bar being connected to negative electrodes of the secondary battery units; and a ground fault detection unit that detects a ground fault of the positive bus bar or the negative bus bar based on an electric current flowing through the first path or the second path.

    摘要: A projection unit projects a predetermined image onto a projection plane through a lens. An image generating unit generates the predetermined image which is to be projected from the projection unit. A code generator generates a notifying image that contains information to be conveyed to another projector provided with an image pickup function. The projection unit projects the notifying image generated by the code generator and has the another projector capture the notifying image so as to convey the information to the another projector.
