Position Fixation TRIZ Cases

A relay apparatus uses distinct reference signal sequences to differentiate direct and relayed wireless transmissions.

Image sensors reduce power consumption by activating only during predicted visibility windows derived from light fixture identifications.

An identification tag merges ultrasound and magnetic induction receivers into identical analog circuits for efficient hardware architecture.

Mobile devices compare surrounding WiFi hotspots against stored data to minimize network lookups and conserve battery life.

Head of train device filters non-linked end of train unit messages using serial numbers and proximity checks to eliminate false alarms from adjacent trains.

Dual bandwidth TDOA location system combines ultra-wideband and wireless local area network signals for precise positioning.

A mobile device computes relative location changes using local sensors and transmits this data to a server for absolute position estimation.

User equipment exchanges location reference signals to determine position, resolving accuracy loss in environments lacking traditional infrastructure.

A distributed acoustic sensing system triangulates gunshot origins in three-dimensional space using fiber optic cables.

A satellite signal receiver uses adjustable time-division multiplexing to control correlation speed via variable clock rates.

Server estimates distances between wireless access points using signal strength data collected from user terminals to build spatial maps.

Adjustable location subsystem modifies spatial and temporal resolution of reported coordinates based on user-defined application preferences.
