1. A wheelchair apparatus, comprising:
- a wheelchair comprising a seat, a seat back and an armrest, and at least one of the seat, the seat back and the armrest is provided with a plurality of sensors;
a data processing unit configured to process data of the plurality of sensors to analyze a user'"'"'s posture and action;
the data processing unit comprising;
a data input interface configured to receive sensed data of the plurality of sensors;
a microprocessor configured to analyze the sensed data to estimate the user'"'"'s posture and action; and
a wireless transmission module configured to transmit the user'"'"'s posture and action to a remote server;
wherein the relationship of the user'"'"'s posture and action and the sensed data comprises at least one of the following;
nobody is using the wheelchair when there is no pressure on the seat, the seat back and the armrest;
the user intends to be seated when pressure is sensed on the front of the armrest and the front of the seat;
the user is seated when pressure is sensed on the rear of the seat and the seat back; and
the user intends to stand up when pressure sensed on the seat back and the rear of the seat disappear and pressure is sensed on the armrest.

Abstract
A wheelchair includes a seat, one or more wheels and a seat weight sensing mechanism. The wheel includes a brake for stopping the wheel. The seat weight sensing mechanism is placed below the seat and is connected to the brake. When the seat is loaded by a weight more than a predetermined value, the seat weight sensing mechanism releases the brake to free the wheel. When the seat is not loaded by a weight more than a predetermined value, the brake stops the wheel.

7. A wheelchair care service network system, comprising:
-
a wheelchair comprising a seat, a seat back, an armrest and a data processing unit, wherein the seat, the seat back and the armrest is provided with a plurality of sensors and the data processing unit processes data obtained by the plurality of sensors to analyze a user'"'"'s posture and action; wherein the data processing unit comprises; a data input interface configured to receive sensed data of the plurality of sensors; a microprocessor configured to analyze the sensed data to estimate the user'"'"'s posture and action; and a wireless transmission module configured to transmit the user'"'"'s posture and action to a remote server; a server configured to store and process the sensed data from the wheelchair; and at least one user interface connected to the server and being configured to allow a care provider to access the sensed data in the server; wherein the relationship of the user'"'"'s posture and action and the sensed data comprises at least one of the following; nobody is using the wheelchair when there is no pressure on the seat, the seat back and the armrest; the user intends to be seated when pressure is sensed on the front of the armrest and the front of the seat; the user is seated when pressure is sensed on the rear of the seat and the seat back; and the user intends to stand up when pressure sensed on the seat back and the rear of the seat disappear and pressure is sensed on the armrest. - View Dependent Claims (8, 10, 11, 12, 13)
