    Abstract: A signal transceiving system and a signal receiver thereof are provided. The signal transceiving system includes a signal transmitter. The signal transmitter includes a first data buffer, a comparator, and an encoder. The first data buffer receives transmitted data and provides previously transmitted data. The comparator receives currently transmitted data and receives the previously transmitted data. The comparator compares, in a first mode, the previously transmitted data with the currently transmitted data to generate a data variation information. The encoder generates, in the first mode, at least one index value and a corresponding instruction signal according to the data variation information. The signal transmitter sends the at least one index value which is a serial signal and the instruction signal to a signal receiver.

    Abstract: A polyhedron lens architecture is disposed in a virtual sphere. The virtual sphere has a horizontal plane, an upper hemisphere above the horizontal plane and a lower hemisphere below the horizontal plane. The polyhedron lens architecture has an upper half part above the horizontal plane, and a lower half part below the horizontal plane. The polyhedron lens architecture includes: multiple bases, which are respectively disposed on the upper half part and the lower half part; and multiple lenses respectively disposed on surfaces of the bases. Optical axes of the lenses intersect at a central point, which is located at the horizontal plane and is a structural center of the polyhedron lens architecture.

    Abstract: In one embodiment, a monolithic integrated circuit includes a first UART, a second UART, and a multiplexer. The first UART has a parallel IO interface to couple to a host system to transceive parallel data and a serial IO interface. The second UART has a parallel IO interface and a serial IO interface coupled to the serial IO interface of the first UART. The first and second UARTs convert parallel data into serial data and serial data into parallel data. The multiplexer has an output coupled to the serial input of the first UART, a first input coupled to the serial output of the second UART, a second input coupled to a serial input of a serial communication port, and a select input coupled to a control signal selectively coupling serial interfaces of first and second UARTs together for remote terminal services at a remote computer system over a network.

    Abstract: An object tracking method and an object tracking apparatus, which are adapted for a low latency application, are provided. In the method, an object detection is performed on one of continuous image frames. The objection detection is configured to identify a target. The continuous image frames are temporarily stored. An objection tracking is performed on the temporarily stored continuous image frames according to a result of the object detection. The objection tracking is configured to associate the target in one of the continuous image frames with the target in another of the continuous image frames. Accordingly, the accuracy of object tracking may be improved, and the requirement for low latency may be satisfied.
