Tire monitoring system, device and method
First Claim
1. A tire monitoring system, comprising:
- a plurality of housing units each positionable within a monitored tire of a vehicle to form an enclosure therein that is unattached and hence is freely movable within said monitored tire;
a plurality of sensor units each positioned within said housing units for detecting at least one predetermined abnormal condition of each said monitored tire and providing output indications thereof;
a plurality of transmitter units each positioned within said housing units and connected with a different one of said sensor units to receive said output indications therefrom, each said transmitter unit including an antenna within said housing units providing output signals responsive to said output indications received by said transmitter units from said sensor units; and
a receiver unit including an antenna for receiving said output signals from said transmitter units, said receiver unit, responsive to receipt of said output signals, providing an indication of said predetermined abnormal condition detection with respect to each said monitored tire.

Abstract
A tire monitoring system, device and method are disclosed for detecting and indicating the presence of one or more predetermined abnormal conditions of tires on a vehicle. The system includes a plurality of monitoring devices (each of which is inserted in a different one of the vehicle tires to be monitored with the monitoring devices being unattached, and thus freely movable, when within the tire) and a receiver unit (mounted to be readily accessible, such as within the cab of the vehicle). Each monitoring device includes a sensor unit and an associated transmitter unit both of which are enclosed within a housing unit that is cushioned, as needed. Periodic output signals indicative of sensed abnormal tire conditions are transmitted from the transmitter units to the receiver unit that includes a reception distance controller and provides an indication of abnormal tire condition detection, responsive to receipt of output signals from the transmitter units within the maximum reception distance, with the indication, normally visually displayed by an indicator, being continuos as long as output signals are received from the transmitter units within a predetermined time interval between received output signals.

8. A tire monitoring device, comprising:
-
a sensor unit, said sensor unit including at least one of a pressure sensor and a temperature sensor with said sensor unit detecting at least one of predetermined low tire pressure and predetermined high tire temperature and providing output indications thereof; a transmitter unit connected with said sensor unit to receive said output indications therefrom and, responsive thereto, providing output signals; and a housing unit enclosing said sensor unit and said transmitter unit therein, said housing unit being configured to be positioned unattached and hence is freely movable within a tire to be monitored. - View Dependent Claims (9, 10, 11)
