Remote-control and robotic lawn mowers reduce physical effort and provide convenient, scheduled maintenance for small to medium yards. They offer safety features and require appropriate storage and supervision.
Smartphones evolved from niche gadgets to everyday tools. They enable emergency contact, navigation, photography, remote work, and more - but bring trade-offs: distraction, health questions, and variable costs. Modern designs focus on durability and connectivity.
The Garmin c340 was a mid-2000s automotive GPS known for on-screen maps, voice directions and route recalculation. Today it remains useful as an offline navigator, but live traffic and current maps are better handled by modern devices or smartphone apps.
A modern overview of how auto GPS works: satellites, trilateration, device roles, accuracy improvements, and what GPS can and cannot do.
Emergency call boxes (blue-light phones, elevator phones, roadside call boxes) remain a practical safety measure. They work when phones fail, are highly visible deterrents, and now often include GPS, IP links, and solar power. Many places still use them, though some jurisdictions have reduced numbers where cellphone coverage is strong.
The Garmin StreetPilot c340 was prized for its simple touchscreen, reliable routing, and flexible mounting. Today it's a capable legacy GPS for offline navigation, but modern smartphones and current Garmin models offer more live features and map updates.
GPS watches combine satellite positioning and onboard sensors to record routes, monitor heart rate and calories, provide navigation, sync to apps, and offer safety features like incident detection and SOS.
Modern vehicle tracking combines GNSS positioning, cellular and satellite comms, and cloud telematics to deliver real-time location, geofencing, diagnostics and fleet intelligence for theft prevention and operational efficiency.
Atomic clock radios sync consumer and infrastructure devices to national atomic standards via radio broadcasts, GNSS, or network protocols. They support everyday convenience and critical systems - telecom, finance, power, and science.
