Abstract: Proposed is a highly reliable information detecting apparatus and method. In an information detecting apparatus and method for detecting transmission information a transmission signal in which a burst period of transmitting a burst signal and a space period as a no-signal period are repeated in a pattern according to the subject matter of the transmission information, whether the absolute value of a signal amplitude level of the transmission signal is not less than a first threshold is detected, whether the absolute value of a signal amplitude level of the transmission signal is not less than a second threshold is detected, and whether the amplitude level displacement of the transmission signal is based on noise or the reception of the transmission information is determined based on the detection results.

Abstract: To adjusts protocol and analog characteristics of an interface automatically, there is provided a data input/output device coupled to a host computer for inputting and outputting data to and from the host computer, including: an interface coupled to an interface of the host computer; and a controller for controlling the interface of the data input/output device, wherein the controller is configured to: measure an analog characteristic of the interface of the host computer and a protocol characteristic of the interface of the host computer when the data input/output device is reset; and adjust an analog characteristic of the interface of the data input/output device to an optimum value based on a result of the measurement, and then adjust a protocol characteristic of the interface of the data input/output device to an optimum value.
