Abstract: A system and method for a motorized mobile chair use a plurality of sensors having a plurality of sensor types to detect a plurality of objects and generate sensor data about the detected objects, each of the detected objects being a person, the sensor data about the objects comprising a plurality of range measurements to the people and a plurality of bearing measurements to the people. The system has at least one processor to receive the sensor data about the people, group the detected people into a plurality of zones, determine a closest person in each zone, and generate one or more control signals to cause the motorized mobile chair to match a speed and a direction of the closest person in the zone corresponding to a direction of travel of the motorized mobile chair while at least approximately maintaining a selected space to the closest person in the zone corresponding to the direction of travel of the motorized mobile chair.

Abstract: A system and method for a motorized mobile chair include at least one processor of the motorized mobile chair to receive sensor data from one or more sensors of the motorized mobile chair, the sensor data comprising attitude data of the motorized mobile chair, determine a tipping of the motorized mobile chair has occurred based on the attitude data of the motorized mobile chair, transmit an authentication key to a remote server, wherein the authentication key, when authenticated by the remote server, corresponds to a unique user account, and transmit at least one of the attitude data of the motorized mobile chair and a communication identifying the tipping of the motorized mobile chair from the motorized mobile chair to the remote server for storage in a memory in association with the unique user account when the authentication key has been authenticated by the remote server and the at least one processor determines the tipping of the motorized mobile chair has occurred.

Abstract: A cushion has at least one fluid chamber and at least one cushion conduit to enable fluid to be added to or removed from the at least one fluid chamber of the cushion. A management system for the cushion has a pressure sensor to measure a pressure of fluid in the at least one fluid chamber of the cushion and to transmit a sensor report with the measured pressure, a tube having a first end connecting to the cushion conduit, a second end leading to the pressure sensor, and a valve to enable fluid to be added to or removed from the at least one fluid chamber of the cushion through the cushion conduit and a processor to receive the sensor report, determine a pressure value of the at least one fluid chamber of the cushion based on the measured pressure in the sensor report, and generate a status indicative of the pressure value of the fluid chamber of the cushion.

Abstract: A system for a motorized mobile chair includes a human machine interface (HMI) to receive one or more user inputs, transmit one or more first control instructions in response to the one or more user inputs, receive one or more second control instructions, and provide haptic feedback through the human machine interface to assist user navigation of the motorized mobile chair in response to the one or more second control instructions. One or more sensors generate sensor data about an area proximate to the motorized mobile chair.

Abstract: A processing system is for a motorized mobile system that provides powered mobility to one or more users. The processing system comprises at least one sensor to measure one or more kinematic states of an object proximate to the motorized mobile system and at least one processor to use at least one object kinematic model as at least one state estimator. The at least one processor predicts a first kinematic state estimate of the object at a first time based on a prior knowledge of state for the object and a measured kinematic state observed by the sensor at a second time to determine a second kinematic state estimate of the object at the second time. The at least one processor outputs the first kinematic state estimate at the first time from the object kinematic model for use by at least one other process of the motorized mobile system.

Abstract: An upgrade system upgrades a motorized mobile chair to a smart motorized mobile chair. The motorized mobile chair has a processing system comprising at least two processors. The upgrade system comprises a plurality of object detection sensors and at least one processing unit connected between at least a first one of the at least two processors of the processing system and at least a second one of the at least two processors of the processing system. The processing unit receives sensor data from at least one of the plurality of object detection sensors, receives at least one control signal transmitted from the first processor, the control signal comprising data, modifies or does not modify the data of the control signal based on at least the sensor data, and transmits the modified or not modified control signal, the transmitted control signal to be received by the second processor.
