摘要： Various implementations are disclosed for an instrumented mobility assistance device, such as an instrumented walker. The device includes an attached sensor that is operable to convert an operational action of a user of the mobility assistance device into a sensor signal. A use analyzer is operable to relate the sensor signal to a contact attribute associated with a contact of the user of the mobility assistance device with an underlying surface. The use analyzer is further operable to determine a gait characteristic of the user, based on the contact attribute. The sensor may include a force or moment sensor. The contact attribute may include a foot-initial contact, or a foot-off contact. In this way, gait characteristics of the user may be determined during normal operation of the instrumented device. Also, the sensor may be used to determine a stability measure associated with the device.

摘要： The invention relates to a control apparatus for an article such as a suitcase with motorized wheels and with a handle for pushing or pulling the article by the user. The apparatus has transducers to sense force applied to the handle pushing or pulling the article. The apparatus has control units connected to each transducer for controlling the speed of rotation of each motorized wheel. The control units increase the speed of rotation of the wheels when the handle is pulled, and the control units decrease the speed of rotation of the wheels when the handle is pushed.
