Deployment Systems

A consequence of this long project cycle is that the number of major customers deploying systems at any one time is relatively small. 

The quality of a system is a measure of how closely it meets all its requirements it is an attribute of the design itself. Some qualities can be observed only during runtime because they relate to the dynamic behavior of the deployed system others must be observed during development or maintenance activities because they relate to the design structure itself and how it can be manipulated. 

A prediction of useful life for solid propellant rockets is quite important, from the standpoint of operational readiness and economic considerations. The premature removal and replacement of deployed systems, based on inaccurate storage life estimates, can be costly. A specific missile system and propellant combination could become obsolete while long term storage data are being compiled. Accelerated aging tests are normally used to give qualitative indications of storability, but the deficiencies of these tests are obvious and are discussed later. 

Now, consider stability. If a satisfactory initial system or component performance and cost are assumed, then in many cases the critical issue is to maintain the physical behavior of materials adjoining an interface for up to 30 years. The physical behavior may include properties that directly influence solar device performance, such as reflectance, transmittance, absorptance, emittance, and photovoltaic efficiency or solar device performance may be indirectly affected by properties such as adhesion, permeability, photo-oxidative stability, or interdiffusion. The required stability of interfaces in SECS components is counter to basic physics and chemistry, because atoms at interfaces must be more reactive and thermodynamically less stable than when in the bulk of materials (2). Yet, the density of solar energy requires deploying systems with large interfacial... 

One of the most common uses for accelerometers is in airbag deployment systems in automobiles. The accelerometers are used to detect rapid deceleration of the vehicle to determine when a collision has occurred and the severity of the collision. Research is currently being done on the use of accelerometers to improve Global Positioning Systems (GPS). An accelerometer can infer position in places such as tunnels where the GPS cannot detect it. They are incorporated into Tablet PCs to align the screen based upon the direction in which the PC is being held and in many laptop computers to detect falling and protect the data on the hard drive. Accelerometers are incorporated into sports watches to indicate speed and distance (useful to runners).

To alleviate the effects of vessel motion, a number of alternative systems have been developed. One of these is a seabed jacking machine (Figure 4.5). This is a device that is tethered to the survey vessel. The advantage of this type of deployment system is that the vessel mohon is not felt by the sampler or sensor. The disadvantage of the system is limited penetration. In the following sections, deployment systems will be discussed in detailed along with sensors, sensor calibration, and special purpose tests. 

The knuckle is electrically driven via a spiroid gear set and has a capability of rotation of +105 and again the stress levels imposed are very high in comparison to previous manipulators with mast diameters of approximately 240mm. The camera remains solidly clamped to the knuckle end as there is no requirement, unlike the peripheral manipulator, to Incorporate a camera deployment system. 

The most widespread type of emission spectroscopy method used to excite the analyte atoms is a plasma that consists of electrons, ions, and excited atoms. In the most frequently deployed system, the plasma is indnced in argon gas by a strong radiofrequency (RF) field (or by microwaves), and is thns called indnctively coupled plasma (ICP) and the method is known as ICP-AES. The plasma is formed when argon gas flows through a torch made of three concentric glass tnbes surrounded by a cooled metal coil with the RF field (Figure 1.18). 

Chapter 20, Section 20.7.3, will discuss the unit building block manufactured in advanced polymer composites and the deployment mechanism by stored potential energy for the skeletal structure. Figure 20.4 of Chapter 20 illustrates the unit building block backing frame of a nine-cluster node point of 21 tubular members. Hollaway and York (1995) have discussed a suitable deployment system. 

Service location descriptor (SLD). Contains the MPEG references to the contents of each component of the programs plus a language code for audio. The PID values for the components identified here and in the PMT must be the same for the elements of an event/program. Some deployed systems require separate manual setup, but PID values assigned to a VC should seldom change.

Boat-deployed systems are those that can be launched and installed by the crew on the boat. For our systems, an installation device is lowered to the sediment. Burial of the anode and placement of cathode and electronics package are started by towing the system with the boat [7]. Our experience has shown that deploying large BMFCs is most easily done with a boat-deployment system such as the systems developed in our laboratory. Therefore, in this chapter, we focus on boat-deployed systems.
