A system and method for a retail customer interfacing with a financial institution through a computer network is presented. A write scan line is disposed for each pixel row of the pixel array section and adapted to convey a write signal to be applied to a gate electrode of the write transistor. A system comprises modules to communicate audit requests, receive responses related to the audit requests, and store the responses. The system also includes a matching module that matches a query image to one or more catalog images. According to the invention, the diaphragm is removed from the particle stream after the specified layer thickness has been reached, and additional particles are directed onto the surface until a specified second layer thickness has been reached. The photodetector further includes a protective unit, and at least a light transmission area, through which the light passes, in a surface of the resin body on an incident side of the light is covered by the protective unit.
