Method and apparatus for enhancing data resolution

A resolution enhancement algorithm is trained on sample images to obtain a polynomial model mapping of low resolution image data to high resolution image data. The polynomial model mapping is applied to other low resolution images to obtain corresponding higher resolution images. The mapping provides resolution enhancement which is superior to that of conventional image data interpolation techniques.

Systems and methods and systems are disclosed for allowing the medium access control (MAC) layer in a communication system within an integrated circuit or device to accurately determine a timestamp point and a timestamp value when, for example, the Precision Time Protocol (PTP) protocol is in use by the communication system. Such determination of accurate timestamp point and timestamp value may be used by the communication system to account for and to compensate for the time shift(s) from forward error correction (FEC) sublayer changes in a data frame that is transmitted by the MAC layer. Feedback is provided to the MAC from the FEC to allow the MAC to accurately determine the timestamp point and timestamp value align preamble of the data frame to the beginning of the FEC bit block that is output by the FEC sublayer.

HYPERFINE INTERPOLATED RANGE FINDING FOR CW LIDAR, RADAR, and SONAR USING REPEATING WAVEFORMS AND FOURIER TRANSFORM REORDERING

Systems, methods, and devices may enhance the apparent sample rate of data collected using Nyquist sampling from a system, such as Continuous Wave (CW) Light detection and ranging (“Lidar”), Radio detection and ranging (“Radar”), or Sound Navigation and Ranging (“Sonar”), that has been modulated with a repeating waveform, such as linear swept frequency, by reordering of the data in the frequency domain. The enhancement of the apparent sample rate may result in a highly interpolated range profile where the data resolution may be enhanced by a factor equal to the number of repeats in the signal being processed, and may result in a highly detained range measurement with a high precision. The various embodiments may combine data from multiple modulation repeats into a single highly interpolated pulse, which may result in a real-time finer range measurement from CW Lidar, Radar, or Sonar systems.

Visualizing a time-variant parameter in a biological structure

The invention relates to a system and a method for visualizing a time-variant parameter at a plurality of positions in a biological structure, wherein a visualization display is configured to display a first representation showing a first visualization parameter at a plurality of time intervals, determined in a first volume between a first and a second boundary of the structure, and to display a second representation showing first and second visualization parameters determined in the first and in a second volume extending between the first and the second boundary of the structure. By providing the user with this combination of the two representations, a higher resolution of data may be processed and meaningfully visualized for intermediate volumes between the first and the second boundary. This is based on the insight that it is desirable to view data between boundaries of a structure as well as at different positions through the structure. However, without simple means of visualization, processing a higher resolution of data is not feasible. This is especially useful when performance differences may be present between the structure at the first and the second boundary. For example, perfusion measurements within the myocardium are different for the endocardial and epicardial layers. Therefore, the relative position of the measurements relative to these layers yields valuable data in the evaluation of perfusion. This increases the information which the healthcare professional can extract from imaging data without complicating the representations required to visualize it.
