2. Normative references
The following referenced documents are indispensable for the application of this document (i.e., they must be understood and used, so each referenced document is cited in text and its relationship to this document is explained). For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments or corrigenda) applies.
There are no normative references in this recommended practice.
3. Defnitions
For the purposes of this document, the following terms and defnitions apply. The IEEE Standards Dictionary Online should be consulted for terms not defned in this clause. 3
accuracy: Closeness of a set of measurements versus the actual value, including precision and trueness.
See also: precision; trueness.
action: Operation generated from a rule. See also: rule.
area: User-defned location or set of locations of interest. See also: location.
association positioning method: Subject-location reported as proximity to another subject. See also:
positioning method.
chokepoint: Egress between two locations. See also: location.
chokepoints positioning method: Subject-location reported as being seen by at an egress between locations.
See also: positioning method.
clinical: Healthcare business processes associated to direct patient care. Contrast: non-clinical.
constraint: Conditions or objects that infuence system performance.
event: Occurrence that triggers a rule. See also: rule.
event history: Set of all events that occurred over a time period. See also: event.
locatable: Identifable device or technique that enables estimation of a subject-location. See also:subject-location.
locatable category: Classifcation of locatable as a) active, when locatable power is internal and locatable positioning initiation is internal, b) passive, when locatable power is external and locatable positioning initiation is external, or c) battery-assisted passive, when locatable power is internal and locatable positioning initiation is internal. See also: locatable; subject.
locatable-position: Position of a locatable. See also: locatable.
locatable-position accuracy: Accuracy of locatable-position estimation. See also: locatable; position.
locatable positioning initiation: Origination of locatable-position estimation, internal or external. See also:locatable-position.
locatable positioning power: Manner in which energy is utilized for a given locatable-position estimation,internal or external. See also: locatable; subject.
locatable-subject association: Relationship method of a locatable with a subject that is either physically attached to a subject, embedded in a subject, a characteristic of a subject, or an inferred association to another subject. See also: locatable; subject.
location: Place described meaningfully for the intended use case in a symbolic, coordinate, or relative convention.
location coverage: Ability to estimate subject-location while a locatable is physically located in a specifc location. See also: location; subject-location.
location-enabled application: Software that utilizes location service data for one or more use cases. See also: location service.
location-enabled application type: A location-enabled application can categorize as either a) native application that has a location interpretation or b) interfaced to a location service. See also: location interpretation; location service.
location interpretation: Process that interprets locatable-position from positioning engine(s) to the subjectlocation. See also: locatable-position; positioning engine; location service.
location naming coordinate convention: Location described as displacement from defned origin (e.g.,X/Y/Z). See also: location.
location naming relative convention: Displacement from another location or subject (e.g., 2 m [5 ft] from
patient bed). See also: location.
location naming symbolic convention: Location described as defned region of space (e.g., room A203).
See also: location.
NOTE—Example hierarchy is as follows:
enterprise: Groupings of campuses relevant to the healthcare system.
campus: Grouping of closely related area/grounds and buildings.
building/grounds: Structure with roof and walls creating indoor spaces.
foor: All rooms or areas on the same level of a building.
subfoor/wing/zone: Contiguous grouping of area/rooms on a foor, typically for a department.
room: Enclosed area of permanent walls, foor, ceiling, and one or more openings, that can be composed of various materials and of various dimensions.
sub-room: Non-enclosed area or temporarily enclosed area of a room (e.g., bay).
specifc: Reserved for defnitive location within sub-room (e.g., bed, fxed cabinet, shelf, chokepoint).IEEE 1847 pdf download.
