Commercial Hybrid IR/RF Local Positioning System
نویسندگان
چکیده
Location-aware applications for supporting the mobile user require reliable information about their position and the environment. Based on a critical review of solutions so far, a very cost effective solution of a local positioning system (LPS) is introduced for the need of positioning indoors as well as on a constrained outdoor campus with dynamic granularity. The simple and costeffective hybrid IR/RF (Infrared / Radio Frequency) technology fits into a suite of distributed Smart IP devices within a scalable and flexible architecture. It enables applications like in-house navigation, user centric home & building automation, or dynamic access control systems.

Solving the local positioning problem using a four-layer artificial neural network
Today, the global positioning systems (GPS) do not work well in buildings and in dense urban areas when there is no lines of sight between the user and their satellites. Hence, the local positioning system (LPS) has been considerably used in recent years. The main purpose of this research is to provide a four-layer artificial neural network based on nonlinear system solver (NLANN) for local pos...
متن کاملHybrid RF Localization inside Small Intestine using Images from Wireless Capsule Endoscopy
Wireless capsule endoscope (WCE) provides a noninvasive method to examine the entire gastrointestinal (GI) tract including small intestine, which other video endoscopic instruments cannot reach. However, since the shape of the small intestine is extremely complex and the length of small intestine varies from 5m to 9m, localization of the capsule inside small intestine is very challenging. Exist...
متن کاملUSRPS - Ultrasonic Short Range Positioning System
A short range positioning system under development is described. A hybrid ultrasonic – RF link is established between three or more transmitters of known positions and a multi-channel receiver fitted to a mobile vehicle. The described system exploits the enormous propagation speed difference between electromagnetic and sound waves to obtain synchronization without the need of precise (and expen...
متن کاملPOS - the Mote Indoor Positioning System ∗
In the past few years, there have been huge research efforts into ubiquitous and context aware platforms that offer a user a custom level of service based on some known local parameters. The utility of such systems is greatly enhanced if a physical locational area can be determined. Recently, hybrid devices have been developed combining low power microcontrollers with short range FM radio trans...
متن کاملGene-Based Marker to Differentiate Among B, A, and R Lines in Hybrid Production of Rapeseed Ogura System
Background: In plant breeding program to produce hybrid varieties, pair of male sterile and restorer fertility lines are required. Differentiation of lines possessing restorer fertility allele from the lines lacking it remove the need for the progeny test, and thus reducing the time and the cost in the hybrid production procedure. Canola breeding program in Iran has concentrate...
