The invention discloses a system for controlling the movement of a personal mobility vehicle. The system includes a processing unit that receives and processes a location data of one or more obstacles over a period of time and determines a change frequency of change of location of the obstacles during the period of time and further generates a movement state categorization of the obstacles categorizing them into either a dynamic obstacle or a static obstacle. The processing unit further determines a dynamic distance traveled by the dynamic obstacle during the period of time and also determines the velocity of the dynamic obstacle. Further, based on the change frequency of change of location, the processing unit determines the movement probability data that relates to the probability of movement of a static obstacle. And, based on the velocity of dynamic obstacles during various time intervals of the time period, the processing unit determines the velocity prediction data which relates to the prediction of the velocity of a dynamic obstacle.

A system and method for a motorized mobile chair using a plurality of sensors having a plurality of sensor types to detect a plurality of objects and generate sensor data about the detected objects, each of the detected objects being a person, the sensor data about the objects comprising a plurality of range measurements to the people and a plurality of bearing measurements to the people. The system has at least one processor to receive the sensor data about the people, group the detected people into a plurality of zones, determine a closest person in each zone, and generate one or more control signals to cause the motorized mobile chair to match a speed and a direction of the closest person in the zone corresponding to a direction of travel of the motorized mobile chair while at least approximately maintaining a selected space to the closest person in the zone corresponding to the direction of travel of the motorized mobile chair.

A patient support apparatus for transporting a patient over a floor surface is described herein. The patient support apparatus includes a drive system with a drive member, a user interface arranged for selective user engagement by a user to operate the drive system, and a control system for operating the drive system. The control system includes a processor configured to determine that the patient transport apparatus is traveling on an inclined floor surface, monitor the user interface for changes in user engagement by a user, and operate the drive system to decelerate the drive member to one of a plurality of positions based on the changes in user engagement.

A mobility aid assembly which may be used for lifting and lowering a user. The assembly includes an articulated lifting arm releasably mounted to a base structure with a first portion of the lifting arm operable between a lowered position and a raised position by a linear actuator. A first end of the linear actuator is pivotally connected to a second portion of the lifting arm with the second end releasably mounted to a second upright portion of the lifting arm. The lower end of the linear actuator disengages from its mounting on the second upright portion when the first portion of the lifting arm is lowered by the actuator to a position in which the first portion of the lifting impinges on the user.

A powered balancing mobility device that can provide the user the ability to safely navigate expected environments of daily living including the ability to maneuver in confined spaces and to climb curbs, stairs, and other obstacles, and to travel safely and comfortably in vehicles. The mobility device can provide elevated, balanced travel.

A person support apparatus with an extendable mattress, a night light message display system, a screen key pendant, egress handle siderails, and various other features. The extendable mattress includes hinged extensions along the sides of the extendable mattress that are moved from a nested position to the extension position. The screen key pendant includes a plurality of screen keys that can be pressed to cycle through various control modes for the person support apparatus. The night light message display system can be configured to display a message or image on the floor communicating information to the person and/or alerting the person as to when they are able to exit the bed.

A lift device includes two vertical extendible tower members, each of the two vertical extendible tower members including, at a first lower distal end, an omnidirectional wheel assembly, and a vertical extension assembly configured to simultaneously raise and lower the two vertical extendible tower members in a vertical direction. The lift device further includes a horizontal extendible transverse member connected between second opposing distal upper ends of the two vertical extendible tower members. The horizontal extendible transverse member further including a horizontal extension assembly configured to extend and retract the horizontal extendible transverse member in a horizontal direction perpendicular to the vertical direction, a traveler carriage configured to move in the horizontal direction upon the horizontal extension assembly between the second opposing distal upper ends of the two vertical extendible tower members, and a payload lifting device configured to raise and lower a payload in the vertical direction with respect to the traveler carriage on the horizontal extension assembly.

The present invention relates to a human-propellable vehicle comprising a chassis and a footplate for receiving a rider's feet. The footplate is movably mounted to the chassis so that at least part of the footplate can be deflected up towards the rider in the event of a collision between the underside of the footplate and an object or terrain passing under the chassis.

The present disclosure describes a system, device, and method for assisting a user to avoid contacting surfaces with their mobile device. An environment is sensed with one or more electronic sensors. The sensor readings are analyzed. Information is then provided to a user based on the analyzed sensor readings. The sensors may be configured so their sensor cones cross at a midpoint. Readings from the sensor(s) may be grouped according detection zone(s) corresponding to one or more areas about a mobile device. A computing module may control a feedback module according to detection zone readings. The feedback module may comprise an indicator for each detection zone. The indicator may be a vibration motor. The indicator may be a light. The computing module may set the colour of a light and/or control the vibrations based on the proximity of surfaces detected within the corresponding detection zone.
