A medical apparatus comprises a first component, at least one second component movable with respect to the first component, a driving device to drive the at least one second component, a sensor to detect a position of the at least one second component, and a controller to retrieve stored data of at least one bounding box of the at least one second component, to calculate actual positions of the at least one bounding box based on the position of the at least one second component as transformed data, and to determine a collision between the at least one second component and the first component or a surface supporting the first component by the transformed data and further transformed data of a further bounding box representing the first component or of a surface supporting the first component.

An operating table is provided. The operating table comprises a base including a column, a tabletop supported by the column, at least one sensor configured to directly detect a change of position of the tabletop, and a controller configured to process signals of the at least one sensor in order to determine a position of the tabletop.

A system and method for providing safety for a motorized mobile system (MMS) are optimized for accurate object detection, the system comprising at least two sensors that are operably configured to generate one or more of a range measurement and a bearing measurement to an object in a field-of-view of the sensors, wherein the range and bearing measurements have associated uncertainties.

Patient handling equipment, such as a hospital bed, is provided with a propulsion system and a status indicator light system incorporated in the propulsion system and operable to generate at least two light beams beyond a perimeter of the bed. The light indicator, which may have different colors, shapes or intensities, can indicate the state of propulsion of the system and generates light beams which are visible all around the equipment so as to be visible to a carer from any angle. The apparatus may include an ambient light sensor disposed to detect floor level lighting conditions rather than general ambient light.

An electrically powered wheelchair has a main frame, a seat frame, a seat back frame, a footrest frame, a wheel section, and an obstacle detection sensor. The seat frame is disposed above the main frame, and supports a sitting seat which supports buttocks and thighs of a user. The seat back frame is disposed behind the main frame, and supports a backrest which supports a back of the user. The footrest frame is disposed in front of the main frame, and supports a footrest which supports feet of the user. The wheel section movably supports the main frame. The obstacle detection sensor is installed in front of the seat frame, and detects an obstacle.

A system and method for providing safety for a motorized mobile system (MMS) are optimized for accurate object detection, the system comprising at least two sensors that are operably configured to generate one or more of a range measurement and a bearing measurement to an object, wherein the range and bearing measurements have associated uncertainties.

A movable object includes a sensing device for detecting traveling-route reflector on a travel surface so that a region outside a floor projection region of the movable object, in particular the traveling-route reflector forward, can be detected. Detecting the traveling-route reflector across a wide range of areas allows traveling control, such as gradual deceleration before entering a curve, speed regulation based on a turning radius at the curve so that centrifugal force on a rider or load is not too great. Also the movable object can detect a branch point or an intersection beforehand, decelerate, and notify the user for user's instruction regarding the traveling direction. Furthermore, for a movable object autonomously traveling with an item mounted thereon, a single sensing device detects the traveling-route reflector and also serves as a safety sensor for avoiding collision with any other objects therearound.

A system and method for providing safety for a motorized mobile system (MMS) are optimized for accurate object detection, the method comprising generating one or more of a range measurement and a bearing measurement to an object using at least two sensors, wherein the range and bearing measurements have associated uncertainties.

A system for physical rehabilitation is disclosed. The system may comprise a plurality of motors configured to be coupled to a ceiling; a plurality of cable portions, wherein each cable portion is connected at a first end to a motor and connected at a second end to a connector element; and a controller in operative communication with the plurality of motors to move the connector element in relation to a staircase.

The present disclosure discloses the surrounding information collection, feedback system and method of the intelligent wheelchair. The system includes a processor, a movement module, and a holder, and the processor is configured to perform operations of receiving information, constructing a map, planning a route, and generating control parameters. The movement module executes the control parameters to move around and includes one or more sensors to detect the information. The holder includes one or more sensors to sense the information.
