The invention relates to a method for determining characteristic-curve correction factors a matrix detector that images in the infrared spectral range. A good image correction can be obtained by virtue of an area of homogeneous temperature being recorded at two different temperatures by the matrix detector, there being two images with different integration times for each temperature. A signal gradient over the integration time is established for each of the pixels from the four pixel values at the two temperatures in each case and the gain being established from the difference of the signal gradients and characteristic-curve correction factors for the gain being stored.

The auxiliary head unit includes a frame for mounting to a head of a user, a scene camera module mounted in or on the frame in a forward-facing orientation, a gaze tracking module disposed in or on the frame and configured to monitor an eye of the user, and an auxiliary controller. The auxiliary controller includes for: acquiring a scene image with the scene camera module, determining a gazing direction of the eye based upon gaze direction data from the gaze tracking module, identifying a sub-portion of the scene image based upon the gazing direction, and wirelessly relaying the sub-portion of the scene image to an IOMD implant within the eye for displaying to a retina of the eye.

A radio receiver is made much more immune to jamming signals. A vector EM sensor, in a 2-dimensional (3-axis sensor) or 3-dimensional (6-axis sensor) sensor configuration, is combined with a unique digital rotation to a preferred direction to create a new reference channel and, using an advanced frequency domain noise mitigation algorithm or other noise cancellation algorithm, can effectively reject jamming and other interference signals and improve the signal-to-noise ratio (20-40 dB) and the receiving performance of the receiver. The method can cancel both near-field and far-field interference and improve accuracy for various applications concerned with establishing the direction, or bearing, to a source. A communication receiver with the vector sensor and the cancellation algorithm has unique anti-jamming capabilities even for multiple jamming sources.
