Traditional communication networks have relied on accurate and dependable location information in order to deliver a range of critical and value-added services for decades. The location of a device attached to a network is a fundamental artifact of any access network, regardless of underlying technology. The success of the Internet, fuelled further by the(More)
Three experiments examined some features of hypnotic induction that might be useful in the development of brief memory-facilitation procedures. The first involved a hypnosis procedure designed to facilitate face identification; the second employed a brief, focused-meditation (FM) procedure, with and without eye closure, designed to facilitate memory for an(More)
Epidemiological studies have shown that loads imposed on the human spine during daily living play a significant role in the onset of low back pain. The loads applied to the lumbar spine are shared by a number of structures: muscles; posterior elements, including facets and ligaments; and the disc of a ligamentous motion segment. In vivo, it is not practical(More)
This document defines key concepts of uncertainty and confidence as they pertain to location information. Methods for the manipulation of location estimates that include uncertainty information are outlined. This document normatively updates the definition of location information representations defined in RFCs 4119 and 5491. It also deprecates related(More)
This document describes a protocol for a Device to provide location-related measurement data to a Location Information Server (LIS) within a request for location information. Location-related measurement information provides observations concerning properties related to the position of a Device; this information could be data about network attachment or(More)
Current location configuration protocols are capable of provisioning an Internet host with a location URI that refers to the host's location. These protocols lack a mechanism for the target host to inspect or set the privacy rules that are applied to the URIs they distribute. This document extends the current location configuration protocols to provide(More)
New fields are occasionally added to civic addresses. A backward-compatible mechanism for adding civic address elements to the Geopriv civic address format is described. A formal mechanism for handling unsupported extensions when translating between XML and DHCP civic address forms is defined for entities that need to perform this translation. Initial(More)
Discovery of the correct Location Information Server (LIS) in the local access network is necessary for Devices that wish to acquire location information from the network. A method is described for the discovery of a LIS in the access network serving a Device. Dynamic Host Configuration Protocol (DHCP) options for IP versions 4 and 6 are defined that(More)
This document describes how holes can be specified in geodetic service boundaries. One means of implementing a search solution in a service database, such as one might provide with a Location-to-Service Translation (LoST) server, is described. Information about the current status of this document, any errata, and how to provide feedback on it may be(More)
