脚穿式障碍检测设备以及对应的方法和计算机程序产品
摘要：
一种用于检测障碍的设备(10)，该设备(10)可由对象(18)穿戴在脚(19)上，特别是集成在可由对象(18)穿戴的鞋类物品(30)中，前述设备(10)包括：至少一个超声源(12T)，用于发射超声发射信号(UT)；超声接收器(12T)，用于接收由障碍(16)反射的相应超声信号(UR)；控制模块(11)，用于测量在超声发射信号(UT)的发射和由障碍(16)反射的相应超声信号(UR)的接收之间的飞行时间(Δt)，并且基于前述飞行时间(Δt)，计算障碍(16)所处的距离(d)。该设备包括：惯性传感器(13)(特别地是加速度传感器)，被设计成沿三个轴(x，y，z)测量脚(19)的加速度；以及控制模块(11)，被配置用于如果由前述惯性传感器(13)测量的前述加速度值遵守用于使能测量飞行时间(Δt)的给定条件(Cen)，则使能超声源(12T)的操作。
摘要（英）：

A device for detecting obstacles (10) that is wearable by a subject (18) on a foot (19), in particular integrated in an item of footwear (30) that is wearable by the subject (18), the aforesaid device (10) comprising at least one ultrasound source (12T) for emitting an ultrasound transmission signal (UT) and an ultrasound receiver (12T) for receiving a corresponding ultrasound signal (UR) reflected by an obstacle (16), a control module (11) for measuring a time of flight (At) between emission of the ultrasound transmission signal (UT) and reception of the corresponding ultrasound signal (UR) reflected by the obstacle (16) and calculating, on the basis of the aforesaid time of flight ([delta]t), the distance (d) at which the obstacle (16) is located. The device comprises an inertial sensor (13), in particular an acceleration sensor, designed to measure acceleration of the foot (19) along three axes (x, y, z), and a control module (11) configured for enabling operation of the ultrasound source (12T) if the aforesaid acceleration values measured by the inertial sensor (13) respect a given condition (Cen) for enabling measurement of the time of flight ([delta]t).
