    Abstract: A method and device for unlatching a door from a frame, using a keyless door latch system, is provided. In one embodiment, a secondary unlocking component receives a signal and derives power from the signal to provide a power source for the keyless door latch system. A microcontroller generates a control signal and an actuator, in response to receiving the control signal, actuates the secondary unlocking component, which allows an energy source, from an exterior of the door, to be transferred to the keyless door latch system for the unlatching of the door.

    Abstract: An embodiment is a computer-implemented method for detecting a straight line in a digital image comprising a plurality of pixels comprising the steps: detecting an edge in the digital image, generating a first straight line which passes through a first pixel of the detected edge, generating a second straight line which passes through a second pixel of the detected edge, which is different from the first pixel, determining at least two intersections with a boundary of the digital image for each generated straight line, determining a set of two parameter values for each generated straight line based on the respective determined at least two intersections, wherein the set of two parameter values uniquely determines the respective generated straight line, and detecting the straight line in the digital image based on the determined sets of two parameter values.

    Abstract: A pattern of symbols is generated and sent to a projector, wherein the pattern includes an array of symbols having a given number of symbol columns and symbol rows, and an image is obtained from a camera. Next the image is decoded in order to generate a decoded pattern of symbols and the depth map is generated as a function of the pattern and the decoded pattern. The image is decoded by placing an array of classification windows on the image and determining the displacement of each classification window in order to optimize a given cost function. Finally, the decoded pattern is generated by determining a respective symbol for each classification window.
