Unique item identifier

RFID tags carry data that represent the unique item identifier (UID) as well as product details to which it is attached. This data is very significant and, if tampered with, can have severe conse-... 

CAS Number - Chemical Abstracts Service Registry Number A CAS (Chemical Abstracts Service) Registry Number is a unique identifier that tells you, for example, that aeetone and dimethyl ketone are actually the same substance. The Chemical Abstracts Service is a division of the American Chemical Society. OSHA only requires certain items on an MSDS and a CAS number is not one of them. However, authors of MSDS s are allowed to add additional information, such as the CAS number, if they desire. The numbers you see on trucks on the highway are not CAS Numbers, butU.S. Department of Transportation (DOT) codes, which are not necessarily specific to each chemical. Their aim is to assist emergency responders. 

The label should be fairly obvious and so will need to be a significant size in relation to the item of equipment. For a small item such as a thermometer, a luggage label would be suitable. For a large instrument, a larger label would be appropriate, perhaps 15 x 10 cm. In each case, some means of fixing the label in place will be necessary. The label should reference any serial numbers which uniquely identify the instrument or its separate parts. The person under whose authority the label has been issued should be identified by signature or initial, and dated. The message should be brief and clear, e.g. OUT OF SERVICE - NOT TO BE USED UNTIL FURTHER NOTICE . 

Table 10-6 presents one type of basic HAZOP form. The first column, denoted Item, is used to provide a unique identifier for each case considered. The numbering system used is a number-letter combination. Thus the designation 1 A would designate the first study node and the first guide word. The second column lists the study node considered. The third column lists the process parameter, and the fourth column lists the deviations or guide words. The next three columns are the most important results of the analysis. The first column lists the possible... 

The vendor shall submit complete parts lists for all equipment and accessories supplied. The lists shall inelude manufaeturer s unique part numbers, materials of eonstrae-tion, and delivery times. Materials shall be identified as specified in 2.11.1.2. Eaeh part shall be eompletely identified and shown on eross-sectional or assembly-type drawings so that the purchaser may determine the interchangeability of these parts with other equipment. Parts that have been modified from standard dimensions and/or finish to satisfy specific performance requirements shall be imiquely identified by part munber for interchangeability and future duplication pmposes. Standard purchased items shall be identified by the original manufacturer s name and part number. 

To ensure the trackability (traceability to the raw data) of analytical results, the laboratory shall have a system to identify test and/or calibration items uniquely. The identification shall be retained throughout the life of the item in the laboratory. 

Committee of Experts has been allocated a unique four-digit number, called the Substance UN Number (or simply the UN Number). Thus a hazardous substance can be distinctly identified by the Substance UN Number (also called the Substance Identification Number or SIN). UN Serial number 0001 to 1000 are reserved for Class 1 items, that is, explosives and ammunition. The nine classes of dangerous goods and hazardous chemicals with a distinctive diamond shaped label bearing a pictorial diagram for quick hazard recognition are ... 

All test and reference items should be identified with a Chemical Abstracts Service registry number or other unique code. Where test items are novel compounds supplied by the sponsor of the study, there should be an agreed-upon identification system to allow the item to be tracked through the study. The composition and concentrations of prepared solutions should be known and recorded. A sample for analytical purposes of each batch of test item should be retained for all except short-term studies. This requirement has the potential to overload storage facilities very quickly, and some sensible arrangement must be made to archive samples of importance, while not giving an inspector cause to worry about inappropriate disposal of items. 

Examination of physical evidence provides two subtle and different types of conclusion. All members of a class or group have identical characteristics. Types of physical evidence which exhibit class characteristics are paint, glass, fibers, fabric, building material, etc. This type of physical evidence is said to be identified. The best that chemical and physical examinations can ever do is to place items into groups of similarly manufactured ilems. It is not possible to differentiate one item of evidence as being uniquely distinguishable from another. 

The equipment list is used in conjunction with the process flow diagram (or P ID). Each item of equipment on the flowsheet should be assigned a unique reference number, and that number is used to cross-reference items in the equipment list. Particular letters may be used to identify similar items of equipment, e.g. reactors as Rxxx, pumps as P-001, etc. 

If the analyst cannot immediately identify the cause, the supervisor should debrief the analyst and all other participants involved in the analysis. A checklist approach to these items would be helpful so that consistency and comprehensiveness is ensured from one investigation to the next. Since there maybe aspects of the analysis that are unique to the particular procedure, the checklist should serve only as a guide, and additional possibilities should be discussed and investigated if deemed appropriate. The examination should include but not necessarily be limited to the following ... 

Databases are electronic filing cabinets that serve as a convenient and efficient means of storing vast amounts of information. An important distinction exists between primary (archival) and secondary (curated) databases. The primary databases represent experimental results with some interpretation. Their record is the sequence as it was experimentally derived. The DNA, RNA, or protein sequences are the items to be computed on and worked with as the valuable components of the primary databases. The secondary databases contain the fruits of analyses of the sequences in the primary sources such as patterns, motifs, functional sites, and so on. Most biochemical and/or molecular biology databases in the public domains are flat-file databases. Each entry of a database is given a unique identifier (i.e., an entry name and/or accession number) so that it can be retrieved uniformly by the combination of the database name and the identifier. 

The FDA and other regulatory authorities require that all major items of equipment be uniquely identified. All the specified components of the system should be present and correct including printers. Visual Display Units (VDUs) and touch screens, keyboards, and computer cards. The identifying serial numbers and model numbers of all the major items must be recorded. The question as to whether units of equipment need to be dismantled in order to check their component details is often raised. If a unit is sealed in such a way that dismanthng would invalidate the manufacturer s equipment warranty, then disassembly should not be attempted it is not required in these circumstances. The IQ should simply check the unique identity of the sealed unit. Processing boards that are clip-fastened into slots in a rack should have their serial numbers recorded, along with their slot position within the rack. It is worth checking with suppliers in advance of delivery whether their equipment does in fact have unique identifiers. 

The order of item presentation was uniquely determined for every student, and each one responded to 10-20 items, depending on his or her success in identifying the situations. SPS continued to present items until the student had made two correct responses to each situation or until the student had seen a maximum of 4 items for any situation still eligible for presentation.1 Thus, every student responded to at least 2 items of each type and to no more than 4. The minimum number of items displayed in the exercise for any student was 10, which occurred only if the student answered all of them correctly. The maximum number that could be presented... 

A unique identification should be given to each study. All items concerning this study should carry this identification. Specimens from the study should be identified to confirm their origin. Such identification should enable traceability, as appropriate for the specimen and study.

IQ Testing. A record of the physical installation of the individual computer systems and their interconnections and interfaces is the result of IQ testing. The purpose is to uniquely identify the component parts of the individual systems, hardware, firmware and software and to verify that they were the items utilized in the supplier acceptance testing. It is often the case, however, that due to supplier acceptance failures, there may have been modifications to the software or replacement hardware performed under change control. 

Equipment Identification. Developing an accurate equipment history depends on reliable means of identifying the equipment. This usually includes a department- and/or facility-assigned unique identification number as well as the manufacturer, vendor, model, and serial number. Identification numbers provided by asset management are often inadequate to allow tracking of interchangeable modules or important items with a value less than a given amount. Acquisition cost is a useful data element.

If the Web is to function at all, there must be some way to uniquely specify a document located anywhere on the Internet. This is achieved through a URI. In essence, the URI naming scheme makes it possible for every item on the Web to have a unique name. Such a naming scheme must also include a technique for identifying the server on which a document is located. Given this, the user of a browser obtains documents by either explicitly entering a URI or by invoking a link that has a URI built into it. 

Traditionally, the snpply chain was designed to track lot or pallet level information for chain of cnstody. Tomorrow in chemical, food, toy, and pharmacentical snpply chains the chain of custody will be defined by tracking each. Each item will have a unique identifier that will be traced across the end-to-end supply chain. This is termed serialization. 

In addition to the tools described for specific searches of the CSD, one of the major requirements for crystal engineering is a capability to compare sets of crystal structures in order to identify degrees of similarity and difference. It is obvious that this task has formed the very basis of the development of crystal engineering, [40] but consistent with the general contemporary trend there is a move towards automated procedures for large-scale structure comparison. The key concept that is required for automation is some unique representation of a crystal structure. Standard items in a CSD entry can cause problems in this respect for example, unit-cell parameters may differ on account of thermal expansion the space group may be influenced by a particular choice of origin... 

There are two fundamental differences between the conventional barcodes and the contemporary RFIDs. First, RFIDs do not require line of sight— that is, objects tagged with RFID can be sensed in a wide area, and there is no need to individually scan all the objects in front of an optical scanner. Second, RFIDs offer item-level tagging— that is, each item within a product range can be uniquely identified (e.g., 109839 is a bottle oforangejuice manufactured by ABC Company ). However barcodes do not identify individual items they can only identify that this is abottle oforange juice manufactured by ABC Company. ... 

One major security issue with the RFID tag is authentication. The data on the RFID tag like the unique identifier (UID) can be easily manipulated or spoofed, as these tags are not tamper resistant (Knospe Pohl, 2004). Anonymity to undesired and anon5mious scanning of items or people. 

Item banks can be created across different patient safety culture instmments and also across different countries or healthcare settings. Based on estimated item parameters, items can be identified with the same and different characteristics across healthcare systems, which will in turn allow a better understanding of similarities and unique attributes depending on the contexts within which healthcare is delivered. 

Functional approach—The functional approach is normally used when hardware items cannot be uniquely identified or when system complexity requires analysis from the top down.
