Obstacle detection

The values found with the glass plates rtd = 1-5209, dis — 2-556 were divided between those given in hg 3 and those given in row 2, table 5, the first being values with the plates moving freely, the second being values with obstacles detected. This division is somewhat arbitrary and it might be that low values in fig. 3 are still due to obstacles. 

These measurement points may be clustered for road surface detection and obstacle detection. Tracking these measurements over time, as implemented, for example by Kalman filtering, not only yields high reliability and accuracy, but also enables acquisition of information that is not directly observable in an image, such as speed or acceleration.

Figure 7 shows the robot designed for experimentation. This robot has four proximity sensors for obstacle detection and two position sensors to locate the robot within the environment. It also has two wheels (motors) responsible for its movement when it establishes its system of sensors. 

The defnon6ttLOtion 0 -chain vaAijant6 In heterozygotes Is complicated by the presence of the large amount of Hb-F. Another obstacle Is the nearly Identical electrophoretic mobilities of Hb-A and the minor Hb-Fi component. Despite these difficulties, abnormalities such as AS, SS, AC, CC, SC, and others can readily be detected using cellulose acetate electrophoresis, starch gel electrophoresis, acid agar electrophoresis, and by CM-Cellulose microchromatography to be described In a separate section. 

Infrared spectroscopy (IRS) is a very powerful technique for the study of adsorbates on electrode surfaces. The two major obstacles to applying in situ IRS are strong absorption of infrared (IR) light by the electrolyte and the difficulty of detecting... 

Optical detectors shall be used in more open configurations where ressure buildup due to the incipient explosion is limited. Optical etectors shall not be used where high dust concentrations limit the reliability of the suppression system. Both uv and ir detectors are available for optical detection. The use of daylight-sensitive sensors shall be avoided to avoid spurious activation. The sensor shall be mounted such that the angle of vision allows it to cover all the protected hazard area. The performance of an optical detector will also be affected by any obstacles within its vision, and this shall be overcome by the introduction of more detectors. Optical detectors shall be fitted with air shields to keep the optical lens clean.
