Hand Carry Item(s) Reminder For Vehicle Passenger 

This invention was made because many taxi passengers leave their belongings in the taxi. Private car users sometimes forget to take the things they should take when leaving their cars. 

This invention is better than that Japanese invention in some important respects:  

1) Its call can be stopped at once by merely a press on a button done by the passenger for stopping the noise disturbance but not switching off the reminder (no need to re-press the button to restore the call function). The time taken for checking if any item is left in the taxi is relatively short.  

2) It can be installed easily just by following its installation instruction and diagrams.

 3) Its cost is much lower (estimated installation cost per taxi door is HK$200.0, or installation cost for three taxi doors is about HK$600.0 or about US$77.0).  Its functions are very stable, it is waterproof and will never ignite any inflammable gas. 

Private cars also need installing reminder call provided by this invention. That can prevent things that should be taken away by their passengers leaving in the car and brings trouble as well as waste of  time.  

The Japanese alarm call installation is inappropriate to be installed in private cars because there can be movable things on the car seat and can make a different image taken before and after a journey causing the alarm call's release. The additional manufacture cost of future cars with this invention is very little. It will be welcomed by buyers.  

Function 1:    Only opening the car door from inside the car can activate a reminder call or speech voice.  

Function 2:  The reminder call can be stopped by merely a press on a button for stopping the noise  disturbance but not switching off the reminder (no need to re-press the button to restore the call function).  

Function 3:   Closing the car door can stop the call automatically.  

Function 4:   If the door opener in the car wants to avoid the call for that time, that button should be pressed  with one finger and held with the cooperation of another one or two fingers until the door's  opening displacement made by the other hand is at least 2 cm and the door-opening handle  returned to its original position.  

There is a sideward push button switch for switching off the reminder. This is appropriate to exist in private cars but should be excluded in taxis because the reminder should not be switched off by any taxi passenger.
