在美国,每年都有数百名儿童在玩弄父母的枪枝时走火射中了自己。同样,在美国,每4名死去的警察中,就有一名是被自己的枪击中的。 为此美国司法部正在研制一种,“智能”手枪,其特点是,在握把上装有传感器,以监视谁在握枪。只有当指定的使用者握住这支枪时才能射击。若这枝枪识别不出谁在握它,它就不开火。 In the United States, hundreds of children fire and shoot themselves each year while playing with their parents’ guns. Similarly, in the United States, one out of every four police officers dead is shot by himself. To this end, the U.S. Department of Justice is developing a “smart” pistol that features a sensor on the grip to monitor who is holding the gun. Shoot only when designated user holds this gun. If this gun does not recognize who is holding it, it will not fire.
