Abstract:
Methods and device for in-system firmware update in an information output device are provided. In one aspect, a method of firmware update in a display device receives a set of data in an image format through a video signal input channel of an input port of the display device. The set of data is converted from the image format to an instruction set format that is different from the image format. A first set of instructions that is used to operate the display device is updated with the set of data in the instruction set format.
Abstract:
One embodiment discloses a method for soldering a cap for an integrated electronic device to a support layer, including the steps of: providing a support layer; providing a cap including a core of a first material and a coating layer of a second material, the first and second material being respectively wettable and non-wettable with respect to a solder, the coating layer being arranged so as to expose a surface of the core; coupling the cap with the support layer; and soldering the surface of the core to the support layer, by means of the solder.
Abstract:
A method for testing a strip of MEMS devices, the MEMS devices including at least a respective die of semiconductor material coupled to an internal surface of a common substrate and covered by a protection material; the method envisages: detecting electrical values generated by the MEMS devices in response to at least a testing stimulus; and, before the step of detecting, at least partially separating contiguous MEMS devices in the strip. The step of separating includes defining a separation trench between the contiguous MEMS devices, the separation trench extending through the whole thickness of the protection material and through a surface portion of the substrate, starting from the internal surface of the substrate.
Abstract:
The method of processing a first digital image by combining the first digital image with a second digital image includes the first digital image being received from a pixel array, and when receiving the first digital image it is converted into a first continuous sequential data stream. The second digital image may be provided in the form of a second continuous sequential data stream, and the first and second digital images may be combined by continuously combining the data in the first and second data stream.
Abstract:
An image sensor array of active pixel elements is arranged in rows and columns. Each column has an output circuit for reading out pixel image signals. The output circuit includes a pair of sample capacitors, a switching circuit operable based upon pixel switches for applying pixel voltages to the pair of sample capacitors. At least one optically masked pixel is provided so that output image signals obtained therefrom represent substantially only the column fixed pattern noise (FPN). An image processing circuit records the column FPN for each column from the optically masked pixels, records the image signal from the sensor array of active pixels, and subtracts the column FPN column-wise from the image signal.
Abstract:
A method for the extraction of shadows in noisy images includes capture of an image, subdivision of the image into a plurality of pixels, definition of a square odd matrix for every pixel having said pixel in the center, application of an algorithm to the matrixes of every pixel, and displaying of an error map of the image. The algorithm is a contour algorithm that includes the operations of =computation of the averages for each corner of the matrix, computation of the averages for the top, bottom, left and right sides, computation of the maximum variance between these eight averages, and comparison with a present value (max variance).
Abstract:
A computer navigation device includes a movement sensor and a trigger device activated by a timer. The computer navigation device periodically transmits to a host computer a pre-defined signal corresponding with the signal that would otherwise be generated by the movement sensor on detection of specific movements of the computer navigation device.
Abstract:
A dual mode radio frequency (RF) front end circuit includes a first transformer for conversion between a balanced and an unbalanced RF signal and a second transformer for conversion between a balanced and an unbalanced RF signal. A first switch is configured to selectively electrically connect to one of the first transformer, the second transformer and an RF transmit port. A second switch is configured to selectively electrically connect the first switch and a filter to one of the input and the output port of an amplifier. The first switch is connected to the input port of the amplifier when the filter is connected to the output port of the amplifier, and the first switch is connected to the output port of the amplifier when the filter is connected to the input Port of the amplifier. The first and the second switch cooperatively selectively connect one of the first transformer, the second transformer and the RF transmit port to the amplifier and the filter.
Abstract:
A WLAN communication system and algorithm that adaptively changes the data transmission rate of a communication channel based on changing channel conditions. The WLAN communication system or algorithm has two modes being a searching mode and a transmission mode. Furthermore, the WLAN communication system or algorithm incorporates an additive increase, multiplicative decrease (AIMD) function into the rate adaptation algorithm.
