ADVANCED WHEELCHAIR
20230056464 · 2023-02-23 ·

An advanced manually propelled wheelchair (100) is described. The wheelchair (100) has a chassis (110). In certain examples this may be a single piece design. The wheelchair (100) may further have one or more of a load adjustment mechanism (150) and a power-assist mechanism. The load adjustment mechanism (150) is configured to adjust a position of a set of rear wheels (120) for the wheelchair (100) relative to a loading of the wheelchair (100). Load adjustment may be performed based on a sensed loading. The power-assist mechanism provides a powered torque to a set of front wheels (130) to help a user propel the wheelchair (100) or to stabilise the wheelchair (100) during use. The power-assist mechanism may be provided as a set of modular front wheel units.

METHOD AND APPARATUS FOR CLASSIFYING ELECTROENCEPHALOGRAM SIGNAL, METHOD AND APPARATUS FOR TRAINING CLASSIFICATION MODEL, AND ELECTRONIC DEVICE AND COMPUTER-READABLE STORAGE MEDIUM

A method and an apparatus for classifying an electroencephalogram signal, a device and a computer-readable storage medium. The method includes: obtaining an electroencephalogram signal; performing feature extraction on the electroencephalogram signal to obtain a signal feature corresponding to the electroencephalogram signal; obtaining a difference distribution ratio, the difference distribution ratio being used for representing impacts of difference distributions of different types on distributions of the signal feature and a source domain feature in a feature domain, the source domain feature being a feature corresponding to a source domain electroencephalogram signal; aligning the signal feature with the source domain feature according to the difference distribution ratio to obtain an aligned signal feature; and classifying the aligned signal feature to obtain a motor imagery type corresponding to the electroencephalogram signal.

CONFIGURABLE POWER WHEELCHAIR SYSTEMS AND METHODS

In one embodiment, a control system for a power wheelchair is provided allowing a user to change the type of input control device throughout a day, week, month, and/or year as their physical and/or mental condition changes. This includes changing input controls from proportional to switch-type devices. A user may start the day when they are not tired with a proportional input control device like a proportional joystick. Then, as the day progresses and the user begins to experience fatigue or exhaustion, the user can change to a switch-type control device requiring less control and dexterity (e.g., less strength and energy) to effectively control the power wheelchair. The user can also start the day with a 4, 3, or 2 switch direction input control and later change to a single switch input control device with scanning. Other combinations are also possible.

Movable object control system

A plurality of thermal areas (11a, 11b, 11c, and 11d) of different thermal environments are formed in a room (11). When it is determined that a person (13) riding on a movable object (20) is feeling uncomfortable in the thermal area (11d), the movable object (20) is remotely operated to move toward the thermal area (11a) where the person (13) feels comfortable.
