Smart occupant alarm system
First Claim
1. An occupant alarm system, comprising an occupancy sensor in combination with an ambient temperature monitor, a logic unit, and an alarm;
- the ambient temperature monitor, the logic unit, and the alarm integrated into a motor vehicle, such that when the ambient temperature monitor detects a hazardous temperature for at least a predetermined time period after the occupancy sensor communicates to the logic unit that an occupant is present, the alarm is triggered.

Abstract
An occupancy alarm system can be integrated into a motor vehicle or can be portable. The occupancy alarm system may be programmed to communicate with a program within a logic unit of the on-board computer within the vehicle or a cellular telephone or other wireless logic device so that if the driver'"'"'s door is open and the engine is turned off but there still is an occupant in the motor vehicle, an alarm is immediately triggered. The GPS coordinates of the motor vehicle or the cellular telephone or other wireless device may be communicated to a remote location service or a local emergency center as part of the alarm. The occupancy sensor may be mounted on the occupant or on the restraint system, and may interact with an ambient temperature sensor and an alarm, both of which may be integrated into a motor vehicle, to indicate that a dangerous condition exists for an occupant within the motor vehicle. The occupancy sensor, the ambient temperature monitor, and the alarm may further be integrated together for a portable alarm system or may be mounted or otherwise integrated onto a portable restraint system. The occupancy alarm system may provide an interface and an override such that when the occupant remains in a potentially hazardous environment, that state is communicated via the interface and, if monitored by a responsible adult, the alarm can be overridden.

3. An occupant alarm comprising:
-
1. an occupancy sensor;
2. an ambient temperature monitor;
3. an alarm; and
4. a logic unit having inputs from the occupancy sensor, the ambient temperature monitor, and outputs to the alarm, such that when the occupancy sensor detects an occupant, and when the ambient temperature is beyond limits of a safe temperature range for a specified time, then the logic unit outputs an alarm signal indicating that a hazardous condition may exist for the occupant. - View Dependent Claims (4, 5, 6, 7, 8, 9, 15, 16, 17)

10. A smart occupant alarm for a child restraint system, comprising:
-
(a) an occupancy sensor;
(b) an ambient temperature monitor electronically connected to the occupancy sensor;
(c) an interface mounted on the child restraint system to communicate to a user a state of the occupancy sensor and the temperature monitor;
(d) an alarm; and
(e) a logic unit having a time delay, the logic unit having inputs from the occupancy sensor and the temperature monitor and outputs to the interface and the alarm, wherein when the state of the occupancy sensor indicates the restraint system is occupied for longer than the time delay and when the temperature monitor indicates that an ambient temperature is beyond preset limits beyond the time delay, when the logic unit communicates to the interface that an alert condition persists. - View Dependent Claims (11, 12)

13. A portable child safety seat, comprising:
-
a first sensor that detects whether the portable child safety seat is occupied;
a second sensor that detects an ambient temperature around the portable child safety seat; and
a logic unit operatively coupled to the first sensor and the second sensor, the logic unit adapted to generate an alarm signal beginning a predetermined time interval after both the ambient temperature is outside an acceptable safety range and the portable child safety seat is occupied. - View Dependent Claims (14)
