Abstract: An automatic zoom-sensing riflescope display adapter (RDA) system can illuminate an iris of a user with a beam from a light emitter. The RDA system can activate a display which includes at least one graphical element visible by the user through an eyepiece. Additionally, the RDA system can focus an image of the iris on a sensor. The RDA system can determine a diameter of the iris from the image of the iris using an iris analyzer. The RDA system can develop a calibration table that correlates the diameter of the iris to a zoom level of an optical scope. The RDA system can estimate the zoom level of the optical scope from the diameter of the iris via the calibration table. Additionally, the RDA system can adjust, to match the zoom level, a font size of the at least one graphical element of the display.

Abstract: A system and method for filtering chirp noise as it passes through a Radio over Internet Protocol (RoIP) gateway in a communication network is disclosed. Radio signals often include a short burst of chirp noise. Incoming signals are buffered and any chirp noise is detected. A chirp filter performs the filtering operation to remove chirp signal while ensuring true audio is not clipped. Without audio clipping the integrity of the audio signals are preserved.

Abstract: A fare gate in a transportation system including a barrier, a sensor, and an actuator. The actuator moves the barrier from the open position into the closed position. The sensor is mounted on the barrier and in one position captures sensor data across an aisle formed by the fare gate. A transit user in front of the barrier in another position is identified by the sensor. The transit user passes through the fare gate using the aisle. The actuator moves the barrier from a closed position to an open position to clear passage through the aisle. Using the sensor, the aisle is scanned with a movement of the barrier. The sensor is calibrated based on a predetermined point with movement of the barrier to align the sensor and the predetermined point.

Abstract: A method and a system for enhancing contrast for an electro-optical video for live streaming is disclosed. An image block from an electro-optical frame of a video is received, where a number of pixels in the image block are identified to compute intensity of the image block. A distribution of intensity of the number of pixels in the image block is determined, and from the distribution, a degree of variation is determined, where a lower threshold and upper threshold for the intensity are determined.
