Patent attributes
A wheelchair system includes a chip assembly configured to be coupled with a wheelchair, the chip assembly including a wireless communication chip. The wireless communication chip is programmed to, in response to the chip assembly coming within a predetermined range of a dedicated short range communication (DSRC) device of an automobile, automatically communicate, through a telecommunications network, a notification signal to the DSRC device that the wheelchair is within the predetermined range. The chip assembly includes one or more chips configured to, in response to receiving an acknowledgment signal through the telecommunications network from the DSRC device, provide an acknowledgment notification to a user of the wheelchair that the notification signal was received. In implementations a geospatial algorithm is stored within memory of the chip assembly, the assembly programmed to determine, using the algorithm, when the wheelchair has experienced an accident event, and to automatically notify one or more persons.
