Visual surveillance

To combat attacks with fast-acting agents in the terminals, continuous visual surveillance of densely populated areas and observation of behavior patterns may be as useful as any detector. The TSA should study the feasibility of the widespread deployment of surveillance cameras in populated areas, coupled with behavioral-pattern-recognition software, as an alternative to chemical agent detectors. Such cameras could also provide a dual-use value in improving the overall security environment. In addition, many critical nodes in the air transportation system (control rooms, emergency-response centers, and so on) are supplied with air that is recirculated from publicly accessible areas this makes them vulnerable to being disabled by the release of... 

Visual surveillance is provided through a closed circuit television (CCTV) system, in which the capture, transmission, and reception of an image is localized within a closed circuit. This is different than other broadcast images, such as over-the-air television, which is broadcast over the air to any receiver within range. 

The pelletizer system does require periodic visual surveillance by an operator in order to maintain a smooth operation. Hence, if maximum automation is desired, the SCCRS is recommended. The SCCRS must be used when it is desired to recycle soot in feedstock too viscous to be pumped at temperatures below 200°F. In the SCCRS (shown in Figure 3) the water/carbon slurry is first contacted with naphtha so that carbon/naphtha agglomerates are formed and the carbon is removed in this form from the water slurry to be mixed with additional naphtha. The resultant carbon/ naphtha mixture is then combined, at an elevated temperature, with the hot gasification feedstock which may be as viscous as deasphalter pitch. The feedstock/ carbon/naphtha mixture is heated and flashed, and then fed... 

Many devices employing the visible spectrum, including the conventional video camera, are available at a reasonable cost. As these devices are subject to the same interferences as visual surveillance, they are used primarily to document the spill or to provide a frame of reference for other sensors. A sub-set of sensors operating in the ultraviolet spectrum may be useful for mapping out a very thin sheen.

The Supreme Court disagreed in an order delivered by Justice Antonin Scalia. The opinion observed that the Court had previously declared that a mere visual inspection from outside is not a search in the meaning of the Fourth Amendment. However, in Katz v. United States (1967), the Court ruled that use of a listening device attached to the outside of a phone booth did violate the Fourth Amendment because the user of the booth has a reasonable expectation of privacy. Similarly, aerial surveillance of a house was not considered a search because a resident has no reasonable expectation that the outside and surroundings of a house will not be seen from the air. 

Psendotnmor cerebri dne to hypervitaminosis A is a ser-ions comphcation, which can canse permanent visual impairment. Patients who take retinoids require proper surveillance. Raised sernm concentrations of retinoids can persist for weeks after withdrawal. 

During the last three decades airborne remote sensors have evolved into common instruments for the operational surveillance of oil pollutions (Goodman 1994, Fingas and Brown 2002, Zielinski 2003). Today s mostly used sensor suites include a side looking airborne radar and an infrared/ ultraviolet detector together with visual observation and video systems. 

In particular, the therapy of severely ill patients with deficiencies of one or several vital systems is based on the surveillance of the important body functions. In addition, the correct function of the medical equipment used and the connections to the patient need to be monitored because a malfunction of devices assisting vital body functions may be fatal for the patient. During intensive care, for continuously monitored parameters automatic alarm systems are used which signal a deviation from preset alarm limits by visual and/or audible alarms and which automatically start a recorder to record selected parameters during the alarm situation. 

Hazard surveillance (gray) Equipment that scores between and including 6 and 11 points on the criteria s evaluation system is visually inspected on an annual basis during the hospital hazard surveillance rounds. 

The interaction between the surveillance officer and the senior weapons director with respect to tracking the helicopter flight on the radar screen involved many dysfunctional interactions. For example, the surveillance officer put an attention arrow on the senior director s radarscope in an attempt to query him about the lost helicopter symbol that was floating, at one point, unattached to any track. The senior director did not respond to the attention arrow, and it automatically dropped off the screen after sixty seconds. Ihe helicopter symbol (H) dropped off the radar screen when the radar and IFF returns from the Black Hawks faded and did not return until just before the engagement, removing any visual reminder to the AWACS crew that...

Product safety experts can usually spot noncorapliant products visually in a matter of seconds or minutes without removing a product s cover. Minor discrepancies found on the outside of the equipment often mean that bigger problems are within. For example, over a two-year period the Finnish enforcement authority obtained over 1,200 products from stores and importers for market surveillance purposes. The inspectors selected products that appeared to have external deviations, such as wrong nameplate, incorrect plug or cord, user manual missing, or unknown trademark. The results of the audit testing were as follows ...
