  • Patent number: 10502781
    Abstract: A detection circuit, a detection method, and an electronic system for detecting an I/O output status are provided. The detection circuit includes a comparison-window generating circuit configured to: detect an I/O data signal, generate a first single pulse signal, determining a first-time window, in response to a rising edge of the I/O data signal, and generate a second single pulse signal, determining a second-time window, in response to a falling edge of the I/O data signal. A first comparison circuit is configured to: receive the first single pulse signal, and compare the I/O drive signal with a preset high-level reference signal within the first time window to obtain a first comparison result. The second comparison circuit is configured to: receive the second single pulse signal, and compare the I/O drive signal with a preset low-level reference signal within the second time window to obtain a second comparison result.

  • Patent number: 9990310
    Abstract: A bus contention detection circuit includes a delay unit having an input terminal for receiving an output signal of an I/O driver, a duty cycle adjustment unit connected to the delay unit, and a comparison unit having a first input terminal for receiving the output signal, a second terminal for receiving a reference voltage, and an enable terminal for receiving an enable signal of the duty cycle adjustment unit. The enable signal has a rising edge that is delayed relative to a rising edge of the output signal and a falling edge that is aligned with a falling edge of the output signal. The comparison unit compares a voltage level of the output signal with the reference voltage when the enable signal is in a stable voltage state and determine a bus condition in response to a comparison result.

  • Publication number: 20100189426
    Abstract: A method and system for automatic zoom adjustment is disclosed. Content is displayed on a display screen for a user. In an auto-zoom mode, a first and a second pictures are acquired. Pre-determined features are detected from the first and second pictures. A first and a second feature distances are computed based on the pre-determined features detected from the first and second pictures, respectively. The first and second feature distances relate to the user's head movement relative to the display screen. An adjustment to the zoom of the content on display is determined based on the difference between the first and the second feature distances.
