The form of the electric vehicle can be switched among different modes according to the requirements of a driver, so that different requirements are met, and the driving experience and safety of the driver are improved.

A mobility aid is provided. The mobility aid includes a mobile base movable along a mobile-base-movement plane, the mobile base having a plurality of wheels. The mobility aid also includes a seat pivotably coupled to the mobile base in a manner so as to be pivotable between a sitting disposition, in which the seat is oriented parallel to the mobile-base-movement plane, and a standing disposition, in which the seat is oriented perpendicular to the mobile-base-movement plane and a sitting surface of the seat is facing forward with respect to a forward-movement direction of the mobile base. The mobility aid also includes a balance-assist unit having a balance-assist-linkage mechanism coupled to the seat, and a body-support-module coupled to the balance-assist-linkage mechanism. Components of the balance-assist-linkage mechanism are jointed in a manner movable to allow movements of the body-support-module relative to the seat along a module-movement-plane parallel to the mobile-base-movement plane when the seat is in the standing disposition.

An apparatus and method for purification of air, is disclosed. The apparatus includes: (a) a mist generator, is configured to generate water micro droplets, (b) a charging chamber, is configured to transfer electric charges to the micro droplets, (c) an interacting space is configured to act as a physical barrier and provide sufficient space for adsorption of air pollutants, (d) a collecting chamber is configured to collect the contaminated micro droplets and convert them to a liquid form, (e) and a water recycling section, is configured to remove the contaminations and provide a usable clean water for the mist generator. The collecting chamber of the apparatus is incorporated with a plastic grid enhanced with surface modified nanofibers to promote the micro droplet collecting efficiency. Further, a method of fabricating a plastic grid enhanced with surface modified nanofibers for an air purifier apparatus is also disclosed.

Methods, systems, and techniques for controlling posture by using eye gaze technology to facilitate position changes in seating, such as in a wheelchair or bed, are provided. Example embodiments provide an Eye Gaze Posture Control System (“EGPCS”) which enables people with advanced motor neuron diseases or disabilities like amyotrophic lateral sclerosis or muscular dystrophy to use eye gaze technologies to control their seating and bed positioning. In one embodiment, the example EGPCS comprises a posture and pressure advisor, logging and telemetry logic, a posture control application, device interface(s) to one or more other devices that control aspects of the powered wheelchair or bed, and eye gaze actuation control. These components cooperate to adjust position of a seat or a bed using eye gaze technology as opposed to by a virtual cursor or by manual control.

A wheelchair system comprises a wheelchair comprising a seat, one or more first sensors disposed on or within the seat, one or more second sensors configured to communicate with the one or more first sensors and configured to be associated with a user to determine if the user is falling out of the wheelchair, wherein, upon detection that the user is falling out of the wheelchair, the wheelchair is configured to automatically stop.

Personal transportation aid that can be converted easily between a wheelchair and a walker. The device has handles that can be pushed forward to switch from wheelchair mode to walker mode. Pushing the handles forward causes the seat bottom of the wheelchair to flip up, opening a space where the user can stand to use the walker; the front wheels of the wheelchair are also pushed forward. Pulling the handles backwards returns the device to its wheelchair configuration, with the seat bottom flipped down and the front wheels moved backwards. Simple mechanical linkages may be used to flip the seat bottom up and down, and to push the front wheels forward and backwards; therefore the device does not require a power source or actuators.

An adjustable back support for a mobility device includes a first adjustable back support assembly including a first support member and a second support member, and a second adjustable back support assembly. The first support member is moveably connected to the second adjustable back support assembly, the first support member being configured to pivot relative to the second adjustable back support assembly relative to a first axis of rotation, and the second support member is moveably connected to the first support member, the second support member being configured to pivot relative to the first support member relative to a second axis of rotation that is not parallel to the first axis of rotation.

A lift which is mainly used in wheelchairs to change the position of the seat and thus to change the position of a person sitting in the wheelchair. On the known scissor lift there is attached an upper frame consisting of a horizontal fixed part 1 and a tilting plate 2 attached to arms 3. In the fixed part 1 of the upper frame, tilting arms 5 are pivotally mounted on axle 4, with the other end pivotally mounted on axle 6 in arms 3 of the tilting plate 1, powered by the actuator 7 mounted in fixed part 1 of the upper frame. Actuator 7 through the levers of the cam tilting system drives tilting arms 5. The tilting plate 2 can be tilted in both directions around axle 6 that is around the attachment point of the arms 3 in the tilting arms 5.

This disclosure describes a low-profile, high-load, and hands-free ball-balancing omnidirectional rolling system with multiple human-robot interfaces for modular and adaptive design configurations and input control interfaces. The disclosed platform uses a self-balancing ball-based robot to allow for a safe, compact, high-load, self-balancing and intuitive mobility device for a person with lower-limb disability. Advanced driving assistance such as obstacle avoidance and semi-autonomous navigation between predefined locations is also disclosed.

An access system includes a laterally extending frame, a carriage in operative connection with the laterally extending frame and including a drive to move the carriage laterally on the frame, a seat support attached to the carriage including a seat assembly interface and a lift to raise and lower the seat assembly interface within a range of positions, a seat assembly attached to the seat assembly interface, a controller in operative connection with the drive of the carriage and the lift of the seat support via which the position of the seat support is controllable, and a controller interface in operative connection with the controller.
