Method of detection of points of interest in a digital image A camera (10) produces a sequence of images (12) processed by a point of interest search algorithm (14) that is parameterizable with a detection threshold (τ) such that the number (n) of points of interest detected in the image varies as a function of the threshold level. The characteristic giving the number (n) of detected points of interest as a function of the threshold (τ) is modelled by a square root decreasing exponential function, which is dynamically parameterizable with values linked to the image to be analysed.

Throughput enabled rate adaptation in wireless networks Rate adaptation in a digital wireless communication network is performed by measuring by a wireless node data throughput values attained while communicating at different data rates on a channel in the network. The node calculates from the measured throughput alone a current transmission rate without any a priori knowledge of a state of the channel. The Regents Of The University Of California

Ultra low power temperature insensitive current source with line and load regulation A temperature insensitive subna current reference is presented with parange power overhead. The main concept is to linearly reduce the gate voltage of a subthresholdbiased mosfet as temperature increases, in order to compensate for exponential dependence of drain current on temperature.

Method, device and computer program for correcting a frequency shift on symbols received by a receiver The present invention concerns a method for correcting a frequency shift on symbols received by a receiver, each symbol being composed of n samples and of a cyclic prefix of a predetermined number Δ samples, the Δ samples being a copy of Δ samples of the n samples. The receiver: —calculates for each symbol, a correlation between at most the Δ samples of the cyclic prefix and the at most Δ samples among the last samples, —averages the correlations over a number of symbols and determines one smooth frequency shift estimation for each averaged correlation, —calculates an exponential from the smooth frequency shift estimation, —delays the received symbols by a delay, —multiplies the exponential by the delayed received symbols..
