A modular tool system is disclosed herein with a power unit, a battery, a controller, a sensor, and a plurality of tool modules. The hand-held sized power unit can include a motor housing and a motor with a shaft. The controller can variably control the shaft. Each tool module can include a housing, a work-engaging portion, a transmission linkage, and an identifier. The identifier is within a range of detection of the sensor when the housings are coupled. Each of the identifiers is distinguishable from other identifiers and the sensor transmits a different signal for each of the identifiers. The controller is configured to determine one of a plurality of different shaft speeds or one of a plurality of different torques to transmit through the shaft in response to the signal from the sensor indicating a particular identifier.

Disclosed is a drive unit for a wheelchair and a wheelchair including such. The wheelchair includes a control input and a structural frame with two lateral frame elements, each supporting a drive wheel. The drive unit includes two drive motors within a driveshaft housing, adapted to drive the drive wheels independently based on input via the control input. The drive shaft housing is releasably attached between the two lateral frame elements of the wheelchair and connected to the drive wheels via quick-release couplings. The drive shaft housing is divided into at least two sections, each section housing one of the drive motors and that the at least two sections of the drive shaft housing are telescopically moveable relative to each other for adjusting the width of the drive shaft housing to different wheelchairs having different distances between the lateral frame elements of the structural frame of the wheelchair.

A vehicle includes a front modular assembly having at least one front wheel, a steering assembly, a throttle, and a power source. The vehicle may include a rear modular assembly removably couplable to the front modular assembly and having at least one rear wheel, a brake selectively coupled to the at least one rear wheel, and at least one rear light configured to emit light while receiving a power signal, the at least one rear light and the brake being in electrical communication with the power source via a shared electrical connection while the rear modular assembly is coupled to the front modular assembly. The vehicle may include a controller in electrical communication with the power source, the controller being configured to selectively provide the power signal to the brake and the rear light via the shared electrical connection.

A motorized armchair for the movement of a person with motor impairments includes an adjustable motorized armchair structure having a resting base, a seat and a back oriented with respect to each other and/or moved integrally with respect to each other relative to the ground. The armchair includes at least one mechanical movement system, provided with at least one actuator and kinematic transmission elements to move and/or orient the seat and back.

The armchair includes a support and movement structure to be fixed to the armchair structure between the resting base and ground having a supporting frame to which at least two driving wheels actuated by at least one motor and two steerable wheels fixed to allow movement of the armchair along the ground. The armchair includes a control interface connected to the motor and actuator to actuate movements of the seat and back and movement of the motorized armchair.

The invention relates to a folding all-terrain electric wheelchair comprising: A triangular support structure (1) provided with two rear wheels (2), traction motors (3) joined to the rear wheels (2), at least two batteries (4), a chair formed by a removable seat (5) and a folding back (8), folding armrests (6) joined to the back (8), a remote or joystick (7), a hinged joint (10) arranged on the free end of the support structure (1) and which enables the assembly and fastening of either an urban wheel (11) or an all-terrain wheel (12), an anti-tipping assembly (15) fastened to the bearing structure (1) and suspension means (16) of the seat. A chair is achieved which is able to be used with maximum comfort on rough terrain, in urban areas, to be folded, to be transported very easily, and has symmetric and asymmetric suspension means, and a very light final weight.

A wheeled personal mobility device for transporting a person, an electric motor for use with the personal mobility device, a splined connection, an electromagnetic braking system and a steering engagement mechanism. The wheeled personal mobility device may be embodied as a wheeled personal mobility aid. The wheeled personal mobility device is reconfigurable between at least three configurations.

A connector structure in an electric mobility device including a mobility body driven by a motor, a seat unit which includes an operation unit to control the motor and which is detachably attached to a seat attachment member of the mobility body, and a seat height adjustment mechanism which adjusts a height position of the seat attachment member to adjust a height position of the seat unit relative to the mobility body. The connector structure connects a signal line provided in the seat unit to a signal line of the mobility body, and includes a first connector attached to the seat unit and connected to the signal line which is connected to the operation unit, and a second connector attached to the seat attachment member and connected to the signal line of the mobility body.

Disclosed is a mobility platform, system, method and, a detachable wheelchair and rickshaw drive assembly (Electric Mobility Attachment) including a chassis connected to a front and rear unit, each unit comprising a respective electrically motorized wheel. The chassis includes an interlocking element extending towards and interfacing-with a structural element on the frame of a wheelchair, such that forward force applied onto the chassis by the front and rear wheels, is conveyed to the wheelchair by the interlocking element, thereby propelling it forward.

It is already known in the prior art to provide muscle-powered wheelchairs with an auxiliary drive, which in the event of a force stress is switched on as needed, and the coupled-in muscular power is increased. Thus far, however, it has not been possible to control the application of the force, which in each case is coupled in intermittently, in such a way that it may be applied in different magnitudes. If a sensor system has sufficient sensitivity to fine movements, the detection for coarse movements is too imprecise, and for a more precise detection of coarse movements, fine movements become overly intensified.

The invention therefore provides that at least one force element that is elastically deformable is associated with the wheelchair. Since the deformation becomes more and more intense with increasing force, this results in natural damping of the coupled-in force, which may be detected by a sensor. As a result, a wheelchair according to the invention may be controlled in a targeted manner for fine movements as well as for faster, coarser movements.

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.
