On-board low-power vehicle condition indicator
First Claim
1. A sensor monitoring system comprising:
- a housing mountable to an exterior surface of a transport apparatus;
a radio frequency (RF) receiver positioned at least partially within the housing, the RF receiver configured to receive RF signals from one or more sensors associated with the transport apparatus, the RF signals including information associated with an output of the one or more sensors;
a processor positioned within the housing and communicatively coupled to the RF receiver, the processor configured to monitor the information associated with the output of the one or more sensors; and
a visual alarm indicator positioned at least partially within the housing and communicatively coupled to the processor, the visual alarm indicator configured to be visible from an exterior of the transport apparatus, the visual alarm indicator further configured to receive power only when changing an indicated state and otherwise maintain the indicated state without receiving power,wherein responsive to detecting that the information associated with the output of the one or more sensors is outside of a predetermined limit, the processor is configured to change the indicated state of the visual alarm indicator,wherein the visual alarm indicator is configured to change state when the information from the received RF signals indicate a parameter is outside of the predetermined limit, andwherein the visual alarm indicator receives power when changing the indicated state.

Abstract
A monitoring unit wirelessly monitors sensor(s) associated with a vehicle and includes (a) a radio frequency (RF) receiver that receives RF signals from one or more sensors; (b) a processing unit connected to the RF receiver that monitors information related received RF signals from the sensor(s); (c) the processing unit monitoring the received RF signals and a status of an output of the sensor(s) associated with the vehicle. The received RF signals may include information on a value of an output of the sensor and limits of acceptable values, and the processing unit generates an alarm when the value of the output is outside of the limits of acceptable values. The alarm may be a visual indication visible from the exterior of the vehicle.

16. A method of monitoring an output of one or more sensors associated with a transport apparatus, the method comprising:
-
receiving, at a radio frequency (RF) receiver of a sensor monitoring system, RF signals from one or more sensors associated with the transport apparatus, wherein the RF receiver is configured to receive RF signals from the one or more sensors associated with the transport apparatus, and wherein the RF signals include information associated with an output of the one or more sensors; monitoring, by a processor of the sensor monitoring system, the information associated with the output of the one or more sensors; presenting an indicated state of a visual alarm indicator of the sensor monitoring system, wherein the indicated state of a visual alarm indicator is visible from an exterior of the transport apparatus, wherein the visual alarm indicator does not receive power and maintains the indicated state without receiving power, detecting, by the processor of the sensor monitoring system, that the information associated with the output of the one or more sensors is outside of one or more threshold values; responsive to detecting that the information associated with the output of the one or more sensors is outside of a predetermined limit, changing the indicated state of the visual alarm indicator, wherein the visual alarm indicator is configured to change state when the information from the received RF signals indicate a parameter is outside of the predetermined limit, and wherein the visual alarm indicator receives power when changing the indicated state.
