摘要： Described herein is an assistance system for an electric personal-mobility vehicle (1a) for a person with reduced mobility. The assistance system comprises sensors (50a) configured for supplying data on the current state of the electric vehicle (1a) and a processing system (60, 2, 3). During a path training step, the processing system monitors a control signal (S1; Da, Db) supplied by a user interface (10a) of the electric vehicle (1a) and drives at least one actuator (30) of the electric vehicle (1a) as a function of the control signal (S1; Da, Db). Moreover, the processing system acquires a plurality of positions of the electric vehicle (1a), processes such position data to generate data that define at least one allowed zone, and stores the at least one allowed zone in a memory (62). Instead, during a normal operating step, the processing system determines the current state of the electric vehicle (1a) as a function of the data supplied by the sensors (50a) and monitors the control signal (S1; Da, Db) supplied by the user interface (10a). On the basis of these data, the processing system estimates a future state of the electric vehicle (1a) and determines whether the future position of the vehicle is within at least one allowed zone stored in the memory (62). In the case where the future position is within at least one allowed zone, the processing system drives the at least one actuator (30) of the electric vehicle (1a) as a function of the control signal (S1; Da, Db). Instead, in the case where the future position is not within at least one allowed zone, the processing system may control the actuators for keeping the electric vehicle (1a) within at least one allowed zone and/or generate an alert signal.

摘要： A patient transport apparatus including a battery system is provided. The battery system includes a battery controller configured to enable power transmission from one or more battery cells to a power output in response to power draw across the power output being below a predefined current threshold. A track assembly, a drive system including a motor disposed in rotational communication with the track assembly to control movement of the patient transport apparatus, and an apparatus controller disposed in communication with the motor and the battery system are provided. The apparatus controller is configured to monitor the power transmission from the battery and to operate the drive system in a current sink mode causing the battery to interrupt power supply upon determining the input current of the battery is greater than the predefined current threshold by comparing the input current of the battery to the predefined current threshold.

摘要： An electric wheelchair propulsion system for a wheelchair. The propulsion system has a first and a second torque transfer hub rotatably mounted to a respective first and second drive wheel of the wheelchair, and an elongated axle tube arranged between the first and second hubs. First and second motors are arranged within the axle tube extending from opposing ends thereof. First and second drive axles are insertable into bores of the first and second hubs respectively, and are operatively connected to the first and second motors respectively. Means are provided to control the actuation of the motors. Actuation of the motors drives a rotation thereof, transferring a torque to the drive axles. The drive axles in turn transfer a torque to the hubs, thereby rotating the drive wheels.

摘要： A caster-wheel assembly (100; 200) for a vehicle, for example a wheelchair or powered wheelchair. The caster-wheel assembly comprises a switch (13) coupled to a housing (3); a castering wheel bracket (9) configured to receive a wheel (10), wherein the bracket is rotatably mounted about a caster pivot axis (28) with respect to the housing; biasing means (15) configured to provide a biasing force such that the wheel bracket is biased away from the housing; and a switch-actuating member (13) coupled to the wheel bracket such that movement of the wheel bracket towards the housing and against the biasing force causes the switch-actuating member to actuate the switch.

摘要： A power wheelchair [4] includes moveable components, motors, a drive controller [6] operatively connected to the motors, and a drive manager device [8] operatively connected to the drive controller [6]. The drive manager device [8] is configured to communicate with an input collection/display unit (IC/DU) 10 via a first communication interface, the IC/DU operable by a user in the power wheelchair. The drive manager device [8] is configured to communicate with a caregiver unit via a second communication interface, the caregiver unit operable by a caregiver. The drive manager device [8] is configured to determine a command made by the user or the caregiver by processing command data received in a communication with the IC/DU or the caregiver unit [12]. The drive manager device [8] is configured to cause voltage to be applied to the drive controller [6] to cause the drive controller [6] to interact with the motors to actuate at least one of the moveable components.

摘要： A motion-based push activation power assist system for manual wheelchairs. The system uses motion-based measurements to determine when the user applies a push to the wheelchair handrims and brakes with the handrims. The push recognition activates a drive system that provides an assistive driving force-pulse to the wheelchair to reduce the demand on the user during propulsion. The brake recognition deactivates the power assist. The provided power assist is proportional to the sensed push and can be modulated to different proportional settings.
