Simple Safe Site Selection (S4) Algorithm

This is a much more computationally efficient method for finding safe landing sites.

This hazard avoidance algorithm uses a single flash lidar range image to select a safe landing site for NASA missions. The advantage of flash lidar is that the entire range image is captured instantaneously, and...

Fast Classification Method for Multivariate Mixtures of Spectroscopic Responses

Method uses a large database composed of correlated predictors.

In many fields of spectroscopy, classification of the measured multivariate response is not always a straightforward process. Accurate classification is limited by many factors that are highly...

Feature Database

The primary function of the Feature Database (FDB) is to contain information about all the ground features seen so far in a sequence of aerial images. This information is organized so that features can be efficiently located and tracked into later images. As each new image is processed, the database grows to include more images...

Peak-Seeking Control Method

Peak-seeking algorithms optimize physical processes in real time and are widely used throughout a variety of industries. However, measuring associated parameters in changing conditions, and responding to them appropriately, is difficult because the measurements are typically distorted by noise. This technology...

Detecting High Stress in Oral Interviews and Text Documents

Content of an interview or text is subjected to various levels of statistical analysis to determine if the person knows the truth and is communicating it.

When a person is interviewed, some of the answers may be inaccurate, or even deceptive, because the person may have either...

Titan Lake and Shore Sampler

The device is suitable for cryogenic dispensing of fluids, and for cryocoolers.

A lake and shore sampling and sample distribution system was developed for a Titan lake environment (93.7 K, in liquid hydrocarbons). The Titan Lake and Shore Sampler (TLASS) would enable the chemical analysis of hydrocarbon lake...

VLBI Antenna Calibration by GPS

This technique could be adapted to monitor deformations of any large outdoor structure including dams, bridges, and buildings.

The determination of local geodetic parameters for VLBI (very-long-baseline interferometry) antennas is traditionally done by conventional surveying techniques. These techniques...

Predicting Heart Age Using Electrocardiography

Knowledge of a patient’s cardiac age, or “heart age,” could prove useful to both patients and physicians for encouraging lifestyle changes that are potentially beneficial for cardiovascular health. This may be particularly true for patients who exhibit symptoms, but who test negative for...
