Time warped modified transform coding of audio signals

A spectral representation of an audio signal having consecutive audio frames can be derived more efficiently, when a common time warp is estimated for any two neighbouring frames, such that a following block transform can additionally use the warp information. Thus, window functions required for successful application of an overlap and add procedure during reconstruction can be derived and applied, the window functions already anticipating the re-sampling of the signal due to the time warping. Therefore, the increased efficiency of block-based transform coding of time-warped signals can be used without introducing audible discontinuities.

Method for evaluating blush in myocardial tissue

Vessel perfusion and myocardial blush are determined by analyzing fluorescence signals obtained in a static region-of-interest (ROI) in a collection of fluorescence images of myocardial tissue. The blush value is determined from the total intensity of the intensity values of image elements located within the smallest contiguous range of image intensity values containing a predefined fraction of a total measured image intensity of all image elements within the ROI. Vessel (arterial) peak intensity is determined from image elements located within the ROI that have the smallest contiguous range of highest measured image intensity values and contain a predefined fraction of a total measured image intensity of all image elements within the ROI. Cardiac function can be established by comparing the time differential between the time of peak intensity in a blood vessel and that in a region of neighboring myocardial tissue both pre and post procedure.

Network connection setup procedure for traffic admission control and implicit network bandwidth reservation

ActiveUS7039712B2Avoid adversely affecting the bandwidth already in useEasy to implementTime-division multiplexMultiple digital computer combinationsNetwork connectionPeak value
A new network connection setup procedure for network computers to set up data transmission connections over a network that implements traffic prioritization (e.g., according to IEEE 802.1p) has the effect of providing admission control and implicit bandwidth reservation. A sending network device (the “sender”) that wants to initiate a new transmission over the network first enters a probing mode in which it sends data packets at a priority level that is lower than the target priority level and at a transmission rate up to a peak probing transmission rate that may be the same or slightly higher than the desired transmission rate. If the sender determines based on feedback regarding the probing transmission that the network can support a transmission at the peak probing transmission rate and the probing priority level, it switches to a steady mode in which it sends data packets at the desired transmission rate and at the target priority level.
