SYSTEM AND METHOD FOR TEMPERATURE SENSING USING THERMOPILE INTEGRATED WITH RIGID PRINTED CIRCUIT BOARD - A simplified explanation of the abstract
This abstract first appeared for US patent application 17930053 titled 'SYSTEM AND METHOD FOR TEMPERATURE SENSING USING THERMOPILE INTEGRATED WITH RIGID PRINTED CIRCUIT BOARD
Simplified Explanation
The abstract of this patent application describes a method for accurately estimating temperatures inside and outside a device using absolute temperature sensors and thermopile heat flux sensors. The thermopile temperature sensing system can measure temperature gradients within the device to estimate absolute temperature at locations that are difficult to measure using absolute temperature sensors. It can also estimate the temperature of objects that come into contact with the device's outer surface, such as a user's skin temperature, and the ambient air temperature. The temperature measurements from the thermopile sensors can be used to compensate for variations in sensor accuracy or reliability due to temperature.
- Absolute temperature sensors and thermopile heat flux sensors are used to estimate temperatures inside and outside a device.
- Thermopile temperature sensing system measures temperature gradients within the device to estimate absolute temperature at hard-to-reach locations.
- It can estimate the temperature of objects in contact with the device's outer surface, such as a user's skin temperature.
- It can also estimate the ambient air temperature.
- The temperature measurements from the thermopile sensors can compensate for variations in sensor accuracy or reliability due to temperature.
Potential Applications
This technology has potential applications in various fields, including:
- Consumer electronics: Accurate temperature estimation can improve the performance and safety of devices such as smartphones, laptops, and wearables.
- Medical devices: Monitoring skin temperature can be useful in medical devices for applications like fever detection or thermal therapy.
- Industrial equipment: Temperature estimation can help in optimizing the performance and efficiency of machinery and equipment.
- Environmental monitoring: Estimating ambient air temperature can be valuable in weather stations, HVAC systems, and other environmental monitoring applications.
Problems Solved
This technology solves several problems related to temperature estimation in devices:
- Inaccurate temperature measurements: By using both absolute temperature sensors and thermopile heat flux sensors, more accurate temperature estimations can be achieved.
- Difficult-to-reach temperature measurements: The thermopile temperature sensing system can estimate temperatures at locations that are impractical to measure using absolute temperature sensors.
- Compensation for sensor variations: The temperature measurements from the thermopile sensors can compensate for variations in sensor accuracy or reliability due to temperature.
Benefits
The use of this technology offers several benefits:
- Improved temperature estimation: By combining different types of sensors, more accurate temperature estimations can be obtained.
- Versatility: The thermopile temperature sensing system can estimate temperatures at various locations, including hard-to-reach areas and objects in contact with the device's outer surface.
- Compensation for sensor variations: The temperature measurements from the thermopile sensors can compensate for variations in sensor accuracy or reliability due to temperature, leading to more reliable measurements.
Original Abstract Submitted
Robust estimation of temperatures inside and outside a device can be achieved using one or more absolute temperature sensors optionally in conjunction with thermopile heat flux sensors. Thermopile temperature sensing systems can measure a temperature gradient across two locations within the device, to estimate absolute temperature at locations that are impractical to measure using absolute temperature sensors. Using heat flux models associated with the device, the thermopile temperature sensing system can be used to estimate temperature associated with objects that contact an outer surface of the device, such as a user's skin temperature. Additionally, the thermopile temperature sensing system can be used to estimate ambient air temperature. Within a device, temperature measurements from the thermopile temperature sensors can be used to compensate sensor measurements, such as when the accuracy or reliability of a sensor varies with temperature.
