Abstract
A digital license plate comprising includes a display system capable of showing a first image and a power supply rail connected to the display system. A display controller is provided with a data connection to the display system and arranged to measure at least one of power consumption and impedance of the power supply rail. The display controller is further configured to prevent sending a second image to the display system if display failure is indicated by measured power consumption or impedance as being below a defined threshold.
Claims20
A digital license plate comprising:
- a display system;
- a first sensor unit configured to measure at least one first parameter associated with the display system;
- and
- a display controller having a data connection to the display system and connected to the sensor unit to receive the first parameter and the display system, the display controller has a first failure threshold for determining whether the first parameter indicates that a display system failure has occurred, the display controller is configured to manipulate at least one function of the display system if a display failure based on impact damage to the display system is indicated by the first parameter as being exceeding a first failure threshold.
A method of operating a digital license plate comprising the steps of:
- measuring at least a first parameter associated with a display system using a first sensor unit;
- and
- manipulating at least one function of the display system if display failure based on impact damage to the display system is indicated by the measured first parameter as being below a defined first failure threshold.
A method of operating a digital license plate comprising the steps of:
- receiving a display update request for a display system;
- measuring at least a first parameter associated with the display system using a first sensor unit;
- and
- if display failure based on impact damage to the display system has occurred as indicated by measured first parameter as being below a defined first failure threshold, abort requested display update.
