Idan-02 201461 ,7'JI I 453576 τηκ pirn rnrriDH runnrr? πϋΊωι rmim INFANT SAFETY ALERT SYSTEM AND METHOD Idan Nachmani Yamit Nachmany Moshe Attias PN V>N n\yD FIELD AND BACKGROUND OF THE INVENTION The present invention relates to child safety systems and, more particularly, but not exclusively, to a system and method for alerting on a child left in a vehicle, when a driver exits the vehicle and the child is left behind.

Every year, thousands of children get injured or die due to being left unattended inside parked vehicles. In some instances, the children are left only for a few minutes. Furthermore, the number of deaths of children left inside parked vehicles, by parents or other drivers, has increased significantly in recent years. It certainly is not the intention of the vehicle drivers to subject the children to such dangers. In many cases, the driver just needs simple reminding of the presence of the children inside the vehicle.

If the outdoor temperature is 90 degree Fahrenheit, the interior temperature of a parked vehicle can rise to 85 degree Fahrenheit in less than twenty minutes. After another twenty minutes, the temperature may rise to 160 degree Fahrenheit. Even if the vehicle's windows are left open, the interior temperature may be only 10 degrees Fahrenheit cooler, which is still a life threatening temperature for a child.

The exposure of a child to temperatures of over 100 degrees Fahrenheit may be fatal for a small child. Such heat rapidly overwhelms the ability of the small child's body to regulate his own temperature. When exposed to such temperatures in the closed environment of a vehicle, children's bodies may go into shock and blood circulation to vital organs may begin to fail, resulting in a heat stoke in a few minutes.

Even if the outdoor temperature is as low as 60 degree Fahrenheit, the interior temperature of a vehicle can reach fatal levels for a child within minutes. The danger is far more fatal than commonly realized, as made evident by the increase in annual occurrences of fatality due to circumstance as described hereinabove. A child's core body temperature can increase three-to-five times faster than an adult's. Consequently, even a quick stop at the store can generally be fatal to a young child. Unfortunately, not enough adults are aware of the risk.

Several systems have been offered to overcome the problem of injury or death among small children left unattended inside parked vehicles For example, US Patent Publication No. 20070268119, entitled "Child abandonment avoidance system for automobiles", to Cram et al., filed on May 18, 2006, describes a child safety system.

The child safety system includes a weight sensor pad for sensing a child's weight applied to an infant car seat, a transmitter to transmit to an alarm device, an alert signal when a child is in the seat, and a door switch. The alarm device is configured to generate an alarm signal if a baby is in the seat and the door switch indicates the driver has left the car.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present embodiments comprise an apparatus, a kit and a method, for alerting on an infant left in a vehicle.

According to an exemplary embodiment of the present invention, there is provided an apparatus embedded in an infant seat deployable in a vehicle.

The apparatus embedded in the infant seat operates an alarm upon an indication that an infant is seated on the infant seat and one (or more) of the doors of the vehicle is opened (say by the vehicle's driver who leaves the vehicle).

The indication that the infant is seated on the infant seat is provided by a sensor which senses the presence of the infant within the infant seat, say a pressure sensor installed inside the infant seat, which senses the infant's weight applied on the infant seat, as described in further detail hereinbelow.

The indication that the door is opened is provided by an infrared light sensor installed on the infant seat. Optionally, the infrared light is emitted from one or more infrared light emitting elements installed inside the vehicle's dome light, as described in further detail hereinbelow.

When the vehicle's driver opens the doors, the dome light is turned on and the infrared light emitting elements emit the infrared light. The infrared light is sensed by the infrared light sensor installed on the infant seat, thus providing an indication that the vehicle's door is open.

Unlike conventional dome lights that emit light in wavelengths similar to wavelengths of day light and wavelengths of street lights in the environment of the vehicle, a light source which emits infrared light is likely to be distinct from the environment lights and thus indicative of the door's being opened.
