The development trend of the car navigation market

According to the GPS report, some subtle changes are taking place in the in-vehicle infotainment market. The growth rate of navigation devices has exceeded the growth of car audio. GPS applications will begin to differentiate after military and instrument navigation to portable navigation (PND). One is to provide positioning services for mobile network devices such as mobile phones, and the other is to target automotive applications, such as C2C (car-to-car information exchange). ), C2I and ADAS (Advanced Driver Assistance System).

In the car navigation market, according to ST's estimates, shipments of PNDs in 2008 will increase by 43% year-on-year, from 32 million in 2007 to 46 million. The main growth driver still comes from the sub-standard penetration rate of the car navigation market, and the education and promotion of the market is still insufficient. Low-cost OEM navigators (dual-use portable navigators) will open up new markets in mid-size cars. It is expected that car-mounted navigators will account for more than 25% of cars sold in Europe and the United States in 2012. The average annual growth rate of the built-in navigator of OEM dashboards will reach 15% in 2007-2013, and the growth rate of portable navigators will be 16%. It is expected that the navigation market will reach the level of automobile influence by 2013.

The development of navigation technology has surpassed the simple point-to-point route guide today. The map-based independent driver assistance system and the collaborative safety system between cars are the next development goals.

Integrated Advanced Driver Assistance Systems (ADAS) and emergency rescue calls in the navigation system will be standard on all premium cars. ADAS includes Adaptive Cruise Control (ACC), Adaptive Frontlight System (AFS), Lane Departure Warning (LDW), and Blind Spot Monitoring. BSM), parking assistance and pre-crash safety systems. However, the introduction of ADAS, in addition to considering the impact of ADAS equipment on the cost of the vehicle, the stability and safety of the equipment operation is also the focus, so the automotive electronics manufacturers must design the related products in cost and stable operation. Under the condition requirements, a balance point can be reached to enter the vehicle supply chain.

Emergency calls are a typical application in the current telematics market, and the European Union has proposed a pan-European emergency rescue service eCall system. In the event of a traffic accident, the car eCall transmitter will automatically send an emergency call to the nearest rescue center. Similar services have been carried out by ON Star in the United States and Japan. There are not many vehicles that load the eCall system, but it is expected to begin to tell growth in 2010. Especially in the European market, more than 70% of new cars will be installed in 2013, and the United States will also have a general car to join ON-Star, while Japan will install 30%.

Looking at the development trend of the navigation market, low-cost, networked car navigation systems (dual-use portable navigation devices) will occupy a certain share in the low-end car market. A navigation system that integrates ADAS and emergency call will be standard on all premium cars. In addition, in order to bring the feeling of home living room to the car, audio and video content playback and file download functions in WMA, MP3, DIVX, MPEG and other formats will be integrated into the car navigation system.

Electric Tea Kettle:

 

Quickly brew the perfect cup of tea or make pour over coffee right at the table with the Electric Tea Kettle. With 1500 watts, this Electric Kettle boils water faster than a microwave, and is safer to use than a stovetop kettle because it automatically turns off when the water reaches a boil. Serving at the table is no problem as the kettle lifts off the base without the cord. Additional features include two water level windows and a pull-lid to make filling and serving easy. 

 

Features:

  •  Thermostat Control – Having a thermostat control allows the kettle to [know" when to shut off. This will prevent damage to the heating element and is an important feature in all modern styles.
  •   Auto shut off/Boil Dry Protection/Fuse â€“ these are three features that are great for protecting the safety of users as well as extending the life of the electric kettle.  The fuse and boil dry protection shut the kettle off if the water gets down below a certain level or if it`s left on for an extended period of time, It doesn`t burn up the kettle.
  • Colors and Designs â€“ Electric kettles come in all shapes, sizes and colors.

  • Savety in Electric- the heating element is typically fully enclosed, with a power rating of 2–3 kW at 220V. In countries with 110V mains electricity, kettles may be less powerful (1–1.5 kW) to avoid drawing too much current and requiring a very thick supply wire.
