Embodiments described herein are directed to a wheelchair system that includes a wheelchair and an exoskeleton. The wheelchair includes a frame, a pair of armrests coupled to the frame, and a control unit. The pair of armrests movable between an attached position and a detached position. When in the attached position, each one of the pair of armrests are coupled to the frame and when in the detached position, each one of the pair of armrests is removed from the frame. The exoskeleton is communicatively coupled to the control unit via a cable extending between the exoskeleton and the control unit. The exoskeleton being releasably coupled to at least a portion of the frame of the wheelchair. The wheelchair system is translatable between a wheelchair mode and an exoskeleton mode such that, when in the exoskeleton mode, the control unit provides electrical power and control signals to the exoskeleton.

A device for improving children's attention to urination includes a streamlined shell; a light module including a liquid sensor and a control unit and a plurality of light sources, the liquid sensor and the control unit and the plurality of light sources are connected one-by-one, the liquid sensor and the light sources are mounted on the surface of the streamlined shell, the control unit is mounted inside the streamlined shell; a power supply module mounted in the streamlined shell and used for supplying power to the light module. It can effectively increase children's attention to urination, keep children focusing on urinating in the liquid draining tray for lighting up more light sources or making sound. It can effectively prevent children from spilling urine out of the potty.

A patient transfer and training aid includes a chassis to which a lifting unit is attached. The lifting unit includes a lifting arm assembly and an active foot support assembly fixed to the chassis. The device also includes a control unit which operates motors of the lifting arm assembly and the active foot support assembly. A patient can activate the foot support assembly to provide vibratory movement of the foot support assembly in order to provide muscle toning and training able to assist in the recovery and rehabilitation of the patient. The device can also be used to aid in the transfer of a patient from one location to another. The device can be used in a variety of different configurations to provide different forms of patient support and training.

A patient transport apparatus for use with a vehicle, comprising a lift mechanism between a base and a support frame to move between an extended configuration defining a first distance and a retracted configuration defining a second distance. An interface generates a user signal. A sensor generates a sensor signal corresponding to force acting on the base relative to the support frame. A controller determines if the user signal corresponds to an extend or retract command; determines if the force acting on the base has exceeded a predetermined threshold value based on the sensor signal; drives the lift mechanism toward the extended configuration where the user signal corresponds to the extend command and toward the retracted configuration where the user signal corresponds to the retract command; and interrupts driving the lift mechanism to stop motion of the lift mechanism in response to the sensor signal exceeding the predetermined threshold value.

A patient support apparatus comprises a base supported by caster assemblies with each caster assembly comprising a stem, a caster wheel, and a caster wheel axle. A patient support surface is coupled to the base and is configured to receive a load. One or more load sensors are integrated with at least one of the stem, the caster wheel, or the caster wheel axle for measuring the load. One or more of the caster assemblies can be coupled to a steering motor, which controls orientation of the caster assembly. A controller can control the steering motors based on analyzing the measurements of the load sensor. The load sensors can produce measurements indicative of both vertical load and non-vertical load applied to the caster assembly. The controller can also analyze the measurements of the load sensor to determine the load received by the patient support surface by negating the non-vertical load.

A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a base and support wheels coupled to the base. An auxiliary wheel is coupled to the base to influence motion of the patient transport apparatus over the floor surface to assist users. A wheel drive system is operatively coupled to the auxiliary wheel to rotate the auxiliary wheel relative to the base at a rotational speed. A throttle assembly having a throttle operably coupled to the actuator. The throttle is movable in a first position, a second position, and intermediate positions between the first and second positions. The rotational speed of the auxiliary wheel changes in a non-linear manner with respect to movement of the throttle.

A person lifting apparatus includes a strap movement system. The person lifting device includes a housing and a lifting strap feeding device located in the housing. The lifting strap feeding device includes a motor connected to a drum and a lifting strap wound on the drum. A sensor provides a signal indicative of force on the lifting strap. A controller receives the signal from the sensor. The controller controls operation of the motor based on the signal. A user input is used to place the strap movement system in a fast mode during which the controller speeds up operation of the motor from a normal operating speed.

Described herein are multifunctional smart beds and methods of operating thereof. Specifically, a multifunctional smart bed comprises a controller, configured to receive input from various sensors (e.g., load cells positioned in bed legs, thermometers, and/or microphones) and/or user. These inputs are analyzed and used to control various bed components to improve the sleep quality, to monitor users' health, score couple's relationship, and the like. For example, these inputs may be used to control the firmness of different mattress portions, change orientations of the head, torso, and/or leg sections, adjust the light, and the like. In some examples, the smart bed generates a report indicating one or more sleep duration, sleep depth profile, sleep scope, heart rate, breath rate, environment conditions, couple's relationship, and the like. Furthermore, in some examples, a multifunctional smart bed is also configured to control external devices in the same environment, e.g., smart switches, smart thermostats.

A caring device includes an adjustment command section configured to give a command for an adjustment of a standing start position of a support member, a standing operation command section configured to give a command for assistance of the standing operation using the support member, and a control device. The control device perform a cooperative operation of the first arm and the second arm so that the support member moves in an up-down direction when a command of the adjustment command section is received. The control device performs a cooperative operation of the first arm and the second arm so that a reference position of the support member moves along different movement trajectories in accordance with the standing start position adjusted by the command of the adjustment command section when a command of the standing operation command section is received.

A barrier overcoming method for a mobile assistive device is disclosed. The barrier overcoming method includes sensing a surrounding environment of the mobile assistive device; determining whether a dangerous terrain exists in the surrounding environment of the mobile assistive device; determining whether the dangerous terrain belongs to a conquerable obstacle when the dangerous terrain exists in the surrounding environment around the mobile assistive device; and adjusting a status of the mobile assistive device to overcome the dangerous terrain when the dangerous terrain belongs to a conquerable obstacle.
