Abstract
A display assembly system which detects abnormal operating conditions, such as gas recirculation or airway occlusion, is provided. An electronic display is located within a housing. Sensors measure characteristics of ambient air ingested by a thermal management subsystem. Weather conditions are gathered for a location, and measurements are received from the sensors regarding characteristics of the ingested ambient air. An alert is generated if the measurements change at a rate different from a rate of change of the weather conditions by at least a preterminal amount.
Claims20
A display assembly system for detecting abnormal operating conditions, said display assembly system comprising:
- an electronic display;
- a housing for said electronic display;
- a thermal management subsystem for the display assembly configured to utilize ingested ambient air;
- one or more sensors for measuring characteristics of the ingested ambient air;
- and
- one or more electronic storage devices comprising software instructions, which when executed, configure said one or more processors to:
- gather weather conditions for a location;
- receive measurements from the one or more sensors regarding characteristics of the ingested ambient air;
- and
- generate an alert if the measurements change at a rate different from a rate of change of the weather conditions by at least a preterminal amount.
A method for detecting abnormal operating conditions for a display assembly system, said method comprising the steps of:
- displaying one or more images at an electronic display within a housing;
- gathering weather conditions data for a location over time;
- determining that the weather conditions changed at a first rate over the time period;
- ingesting ambient air into the housing;
- measuring characteristics of the ingested ambient air over a same or different time period;
- determining that the characteristics of the ingested ambient air changed at a second rate over the same or different time period which is different from the first rate by at least a predetermined amount;
- generating an alert;
- and
- transmitting said alert to at least one electronic device located remote from said electronic display.
A method for detecting abnormal operating conditions in a display assembly, said method comprising the steps of:
- displaying one or more images at an electronic display within a housing;
- determining, by way of one or more location detection devices, a location of said display assembly;
- activating one or more fans to ingest ambient air into an open loop pathway extending through at least a portion of the housing;
- gathering, by way of a network interface device for the display assembly, ambient air temperatures determined by a weather station approximate said location over a historical time period;
- measuring, by way of one or more sensors, temperatures of the ingested ambient air in the open loop pathway over a current time period;
- determining that a rate of change of the temperatures of the ingested ambient air as reported by said one or more sensors are not within a margin of error of an anticipated rate of change of the gathered ambient air temperatures based on said gathered weather conditions over the historical time period;
- generating an alert comprising a request for service of the display assembly;
- transmitting, by way of the network interface device, said alert to at least one remote electronic device, wherein said alert indicates existence of the abnormal operating conditions and requests servicing of the display assembly;
- and
- adjusting operations by at least one of:
- decreasing an illumination level for said electronic display, and increasing a speed level for said one of more fans.
