Our device using the wireless signals presented with infrared this time would not be reflected if the people wearing it was in an open space, neither would the receiver proceeded anything. In other words, the infrared signals would be reflected if they confronted the obstacles in predicted distance and receive d by the receiver and started the alarm to inform blind people to be careful.
The submission is about the safeness shoes for blind people. It provides the convenience and safety for the blinds when they walk and do any activity. The safety device of the shoes are the combination of start switch, tappet switch, power supply body, wireless launcher, wireless receiver and the alarm. Out surface of the shoes there are settings of the start switches, and tappet switches beneath the shoes. The power supply bodies are on the side of the tappet switches, and the wireless launchers are at the front, which can launch the signals. The wireless receiver and the alarm are at the back of the shoe body. The wireless launcher would remain silence while the tappet witch at the bottom of the shoe body was bulging, but it would launch the signals while the tappet switch was pressed into the shoe body. If the signals were confronted by the obstacles, the reflection would received by the receiver and then started the alarm to keep the blinds alert.
ADVANTAGES OF OUR INVENTION
Outstanding Characteristics of the Invention Compared with learning skills such as using walking sticks, which need to be carried all the time, or using guide dogs, which need more money and time to train and feed, our design uses the signal reflection in predicted distance to start the alarm to inform the blind people to avoid the obstacles. Besides, we use the tappet switch device to let the launcher start only when the bottom of the shoe body touches the ground, and it may decrease the waste of power and misjudgment. This cost effective and practical product will surly be used by most of the blind people.
OTHER POINTS YOU SHOULD NOTICE
The wireless launcher would remain silence while the tappet switch at the bottom of the shoe body was bulging, but it would launch the signals while the tappet switch was pressed into the shoe body. So we use the tappet switch device to let the launcher start only when the bottom of the shoe body touches the ground, which may decrease the waste of power. It also decreases the misjudgment rate since the launcher at the front of the shoe not being horizontal to the ground while the shoe isn't on it, which may launch the wrong signals, will be controlled by the tappet switch.
OPERATION AND ITS EFFECTS OF OUR INVENTION
The device is set in at least one shoe. Out surface of the shoe there is a setting of the start switches, and a bulging
tappet switch beneath the shoe. The power supply body, recharged with the battery inside of the shoe and supplying the power to the wireless launcher, receiver and the alarm is on the side of the tappet switch. The wireless launchers are at the front of the shoe, which can launch the signals of infrared or ultrasonics. The wireless receiver and the alarm are at the back of the shoe body.
The wireless launcher would remain silence while the tappet witch at the bottom of the shoe body was bulging, but it would launch the signals while the tappet switch was pressed into the shoe body. If the signals were confronted by the obstacles, the reflection would receive by the receiver and start the alarm, like the whistle or vibration, to keep the blinds alert.
