ABSTRACT:
FIELD OF THE INVENTION
The invention is an apparatus, method and system for providing remote monitoring of a person's need for assistance without necessarily monitoring physiological conditions at the person. More particularly, the invention monitors user spatial orientation, velocity and acceleration changes, and based on these changes, the invention determines if assistance may be required. The invention determines the location of the user and selectively communicates the location; orientation information obtained from the spatial orientation, velocity, and acceleration sensors; and the current alert status to a remote location.
PROBLEMS IN THE ART
There is an ever-growing number of people that engage in independent and/or active lifestyles but still may be susceptible to injury. Friends, family, loved ones, caretakers, caregivers, and other persons may not always be physically present to accompany or monitor the person. The friends, loved ones, caretakers, caregivers, and other persons may, however, want to be notified in case of any emergency situation involving the person susceptible to injury. One solution to this problem has been physiological monitoring. One example of physiological monitoring is the commonly owned application titled APPARATUS, METHOD AND SYSTEM FOR REMOTE MONITORING OF PHYSIOLOGICAL CONDITIONS, filed on Sep. 20, 2000 and having Ser. No. 09/666,732. In physiological monitoring, a person or user is connected to one or more physiological monitoring devices to monitor vital signs or other physiological information. Physiological monitoring has had numerous problems.
Typically, a physiological monitoring device senses physiological conditions of the user and immediately transmits these conditions to another location which remotely processes the information. Problems are present in the communication link from the device on a user to the central location. Some problems are related to the amount of physiological data that is sent. In order to properly monitor the vital signs or other physiological information of the user, frequent or continuous transmissions must be made. These transmissions may consume more bandwidth and more power than is desirable.
Another related problem concerning physiological monitoring devices involves the integrity of the information received over the communication link. Particularly where there is a large amount of information being transmitted in the process, there is the opportunity for this information to be corrupted. Where physiological information is corrupted in the transmission process, the goal of monitoring for emergency events and conditions is not fulfilled.
In addition, there is a security or privacy problem associated with transmission of physiological information. Users are not particularly amenable to having their physiological information capable of being monitored by third parties. Although these problems may be addressed through some extent through error checking and encryption, attempts at solving these problems may increase the bandwidth, or otherwise increase the overall complexity and cost of the device.
Another related problem is that these continuous transmissions of physiological data require additional power requirements that may make it infeasible for a battery operated device or else may result in a device that is large or cumbersome or requires frequent battery replacement.
In addition, the remote processing of this information may take considerable time. If there is a medical emergency, this must be known as soon as possible so that there is adequate time to respond to the emergency.
A further problem is that even when the physiological conditions of a user are monitored, the location of the user needs to also be known so that medical assistance can find the user if required.
Yet, another problem with physiological monitoring is that physiological monitoring requires a complex device such as with multiple sensors attached to the users body and other inherent constraints in current designs. These constraints make physiological monitoring inconvenient, uncomfortable and undesirable for users. In addition, these extra sensors may require design complexity that increases the overall size of the device. A larger, heavier device is also inconvenient for users to wear.
Another problem with physiological monitoring involves false alerts due to inaccurate monitoring. Physiological sensors may become displaced or detached from the body area they are monitoring. This results in the transmitted physiological readings not being reflective of the actual physiological condition of the user. Those monitoring the physiological conditions may only know the physiological readings and not realize that the sensors are simply not properly attached. This may result in false alerts.
These and other problems have made remote monitoring of people cumbersome, inconvenient, or sometimes unworkable.
