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.

An electric mobility vehicle in a facility includes a mobility body having a wheel, a driving unit driving the wheel, and a seat for the user, and sensors, and the mobility body has a controller which controls the driving unit for at least one of automatic driving and automatic stopping by using detected data of the sensor, the controller is configured to be able to set a detection cancel area, which is an area where a part of the user can exist in front of the user, the electric mobility vehicle further includes a lower side sensor which detects an object to be avoided from under a footrest surface or from a front end portion of a footrest portion.

A personal mobility vehicle 1 includes one or more automation components, a vault 2, and locking means 3 adapted to lock the vault 2. The automation components include at least one of a motor controller, computing processors, or a battery to power other automation components, or combination thereof. The functional components are the components that either display various information related to navigation of the vehicle, or receive inputs to be processed by the computing processor or microcontroller, or receives triggers from the motor controller or the computing processor regarding the functioning of the functional components, or combination thereof. Inside the vault 2, the automation components are placed, such that the automation components are functionally connected to other functional components of the vehicle 1. The embodiment helps to safeguard the automation components, and keep them protected, such that authorized personnel have access to the automation components inside the vault. These automation components are critical to functioning of the vehicle 1.

A kit of parts which when assembled will provide a wheeled chair and include a central frame member to which all other elements are connected.

An improved sit-to-stand wheelchair having a base for engaging a surface and carrying a power actuated elevating drive supporting a patient seat and a wheels with improved footrests that may be retractable, said power actuated elevating drive simultaneous elevating the seat and lowering the base into fixed engagement with a surface when the patient desires to move to a standing position.

A mobile wheelchair/chair, especially for the disabled, having a body support system mounted on the casing, a swivel and drive assembly and castors is characterized in that the swivel and drive assembly equipped with drive motor (8) and swivel motor (5) has s form of coupled vertical fixed fork (6) furnished with at least one swivel wheel (7), and seat (3) is mounted on the steering and swivel axis of fixed fork (6), with swivel motor (5) located in the upper part of the steering and swivel column (6a) of fixed fork (6). Casing (1) is equipped with castors (2) in its lower part.

A footrest mechanism, comprising a chair support body, a locking component and a leg component. The locking component comprises a locking rod, a locking arm and a locking elastic member. The locking rod is pivotally connected to the chair support structure. The locking arm is pivotally connected to the leg component and the locking rod, respectively. The locking elastic member is connected to the chair support structure and the locking arm, respectively. The locking arm can be locked to the chair support structure to define a locking state and the locking state can be maintained due to an elastic deformation of the locking elastic member. The leg component is pivotally connected to the chair support structure and in a transmission connection with a driving component, and the leg component is capable of rotating relative to the chair support structure when the leg component is driven by the driving component.

A mobility device positionable between a powered transport position and a powered wheelchair position is provided. The mobility device includes a frame including a pair of side rails, a pair of wheels on each side rail, a distance between each wheel on a corresponding side rail defining a length of the mobility device, a pair of arms coupled to an end of the pair of side rails, and a seat member positioned between the pair of arms. A pair of foot plates is pivotally attached to the pair of side rails and rotatable between an unfolded position in which the foot plate is horizontal and a folded position in which the foot plate is vertical. Each foot plate having a length at least substantially equal to the length of the mobility device.
