Abstract
In one aspect, a wheel chock system is provided that includes a wheel chock with a sensor configured to detect a proximity of a wheel, and a controller operably coupled to the sensor and a peripheral device. The controller includes a processor configured to cause the peripheral device to have a first state in response to the sensor detecting the wheel within a first proximity. The processor is further configured to initiate a timer in response to the sensor detecting the wheel within a second proximity. The processor is further configured to cause the peripheral device to transition to a second state in response to the sensor detecting the wheel within the second proximity for a predetermined time period measured by the timer.
