Abstract: A server including a backplane, first and second EM units is provided. The signal of the first EM unit is determined whether or not to be transmitted to a bus at the backplane according to statuses of the first EM unit and other EM unit(s). The signal of the second EM unit is determined whether or not to be transmitted to the bus according to statuses of the second EM unit and other EM unit(s). Thus, the server prevents the first and the second EM units on the backplane simultaneously connected to the backplane to cause a signal short between the first and the second EM units.

Abstract: A test method for a plurality of circuits respectively having inputs for greatly reducing the required test time and the control circuit complexity is provided. The method includes steps of providing a set of test patterns for detecting a characteristic of the circuits, providing a common data line, and electrically connecting the circuit inputs to the common data line so that the test pattern can be broadcasted to the circuits through the common data line. The present invention also provides an architecture for implementing such method.

Abstract: A method and system are provided to identify coordinate information of a selected position on a three-dimensional object or on a leaf among plural pages with pre-formed reference indications. While identifying the coordinated information on the leaf, identification of page number is accomplished based on the reference indications formed around margins of the sheet. Moreover, by using at least one corner of the leaf and symbols printed around the margins as the reference coordinate data, the actual coordinate information of the selected position is derived. Corresponding to the actual coordinated information, accessory data in a form of voice, image or text are then output.
