I-PRF/C-PRF is emerging as a promising treatment modality for skin rejuvenation. These PRF products can be used as an anti-aging modality and for improving blemishes, acne scars and skin tone and texture. These can also be used for improvement of tear trough, nasolabial folds, marrionnete lines, peri-oral lines and skin of neck, chest and hands.

An adaptive procedure for selecting radar pulse repetition frequency (PRF) bas been developed as the primary means of minimizing the occurrence of range aliased echoes within operationally significant coverage areas (e.g., airport runways) of the …

By carefully selecting the pulse repetition frequency (PRF) of the radar, range obscuration from distant storms can be minimized over specified airport regions. This document describes techniques for predicting the obscuration as a function of PRF, and details the criteria which shall be used by the TDWR system to automatically and adaptively ...

This paper presents a technique that enables the estimation of spectral moments of overlaid first and second trip weather echo signals in a pulsed Doppler radar. The transmitted pulses are phase…

Table 7 provides a mechanism for quantitatively assessing the effectiveness of the PRF selection technique in reducing potential obscuration levels. Another means by which to analyze performance characteristics of the technique is to examine obscuration conditions following PRF selection over the distribution of total track time.
