Patent 6850172 was granted and assigned to LG on February, 2005 by the United States Patent and Trademark Office.
A portable vehicle parking assistance device has a base and a vertical shaft to which is coupled a motion detecting sensor and an alerting mechanism; namely, a light or horn. The device also has a combination carbon monoxide and smoke detector, which is linked to the alerting mechanism. When the device is bumped by a vehicle during use or when the combination carbon monoxide and smoke detector detects the presence of these fumes, the alerting mechanism is actuated, thereby notifying the vehicle operator.
