[0017] Referring to FIGS. 1-3, reference numeral 10 generally designates an eyewear assembly. The eyewear assembly 10 includes a frame housing 12 wearable by a user. The frame housing 12 defines a first lens position 14 and a second lens position 16 spaced to be aligned with different ones of the user's eyes, respectively. A first display 18 corresponds to the first lens position 14, and the first display 18 is configured to present a first image for viewing by one of the user's eyes. A second display 20 corresponds to the second lens position 16, and the second display 20 is configured to present a second image for viewing by the other of the user's eyes. A fan assembly 22 is configured to circulate air from an air input vent 24 through an air output vent 26. A plurality of temperature sensors 28 are located at different locations within the frame housing 12, each of the plurality of temperature sensors 28 has a first threshold temperature and at least two of the first threshold temperatures are different. A central processing unit 30 ("CPU") is configured to activate the fan assembly 22 with a first activation signal upon one of the plurality of temperature sensors 28 reaching the first threshold temperature.

[0018] With reference now specifically to FIG. 1, the frame housing 12 may include a first lens 32 covering the first lens position 14 and first display 18 and a second lens 34 covering the second lens position 16 and the second display 20. A first temple bridge 36 extends from a location proximate the first lens position 14 and is configured to extend over a user's first ear and a second temple bridge 38 extends from a location proximate the second lens position 16 and is configured to extend over a user's second ear. A bottom edge 40 of the frame housing 12 defines a central recess 42 for resting on a user's nose. The frame housing 12 may include buttons 43 for operating the various electronic components in the eyewear assembly 10 and a charging port 44 for charging a battery (not shown) and / or otherwise power the electronic components in the eyewear assembly 10. In some embodiments, a speaker 46 is located, for example, on distal ends of each of the temple bridges 36, 38.

[0019] With continued reference to FIG. 1, a camera 48 may be located between the first lens position 14 and the second lens position 16. The camera 48 may be configured to capture the first and second images generated on the first display 18 and the second display 20. Further, the first display 18 and the second display 20 may display images other than the images captured by the camera 48. In some embodiments, the first display 18 and the second display 20 may be configured to merge images captured by the camera and images produced by a control system (e.g., the CPU 30) to present semi- virtual or hybrid images. The images produced by the control system may be stored in a non-transitory memory (not shown), and includes a storage management module that manages one or more partitions within the memory. In some embodiments, the memory may include flash memory, semiconductor (solid state) memory or the like. The memory may include Random Access Memory (RAM), a Read-Only Memory (ROM), or a combination thereof. The memory may include instructions that, when executed by the control system (e.g., the CPU 30), cause the control system (e.g., the CPU 30) to, at least, perform the functions and method steps as described herein.

[0020] With reference now to FIG. 2, the plurality of temperature sensors 28 may be associated with different ones of the electronic components. The electronic components may include two or more of the first display 18, the second display 20, the camera 48, a system-on-chip 50 ("SOC"), the central processing unit 30 ("CPU"), and an inertial measurement unit 52 ("IMU"). For example, the temperature sensors 28 may beassociated with three or more of the electronic components, four or more, five or more, six or more, and / or each of the of the electronic components. It should be appreciated that each of the electronic components may have operational temperature guidelines corresponding to at least the first threshold temperature. More particularly, the first threshold temperature is associated with a temperature in which it is beneficial to cool the associated electronic component. As the electronic components have different operational temperature guidelines, the plurality of temperature sensors 28 ensures that each component is operating below the corresponding threshold temperature. While the temperature sensors 28 could employ any type of temperature sensing technology, it should be appreciated that the temperature sensors 28 may be configured as thermistors in operable communication with a control system (e.g., the CPU 30). It should be appreciated that the control system may be synonymous with the CPU 30 or may be a discrete control system, a processor, a logic control circuit, and / or the like.

[0021] With reference now to FIGS. 3 and 4, the air input vent 24 may be defined by the frame housing 12 proximate the bottom edge 40 aligned with the first lens position 14 and the air output vent 26 is defined by the frame housing 12 proximate the bottom edge 40 aligned with the second lens position 16. As generally shown with the arrows in FIGS. 3 and 4, the locations of the air input vent 24 and the air output vent 26 form a ventilation path that may substantially pass by each of the electronic components to facilitate cooling. The ventilation path further removes any warm air that may be trapped within the frame housing 12 by replacing the warm air with ambient air suctioned in through the air input vent 24. As best illustrated in FIG. 3, a nose pad 54 may be connected to a portion of the bottom edge 40 that defines the central recess 42 for resting on a user's nose and generally positioning the first display 18 and the second display 20 in alignment with the user's eyes. As best illustrated in FIG. 3, the air input vent 24 and the air output vent 26 may each be defined by a plurality of apertures extending through the frame housing 12. The apertures for each of the air input vent 24 and the air output vent 26 may be in groupings, for example, a first grouping proximate the bottom edge 40 and a second grouping extending along a side (e.g., orthogonal to the bottom edge 40) and under the temple bridges 36, 38. As best illustrated in FIG. 4, the electronic components may be in communication with the control system (e.g., the CPU 30) and / or each other via a printed circuit board ("PCB") 56 that is located in theframe housing 12. The temperature sensors 28 (e.g., thermistors) may be operably coupled to the PCB 56 and / or otherwise in close proximity (e.g., coupled, connected to, etc.) to the electronic components. A heat sink 58 may extend across at least a portion of the PCB 56 (e.g., over the CPU 30) to dissipate heat from one or more of the electronic components. The fan assembly 22 includes a blower or fan 60 and a carrier 62 coupled to the frame housing 12 that locates the fan 60 within the frame housing 12 (e.g., with fasteners). The carrier 62 includes a seal 64 that, in combination with the carrier 62, at least partially pneumatically isolates a front 66 the fan 60 and the input vent 24 (e.g., a plurality of apertures and / or grouping of apertures) from the output vent 26. The seal 64 may extend between and seal the carrier 62 and the second lens 34 and form a hermetic or semi-hermetic boundary around the front 66 of the fan 60, such that only the fan 60 provides fluidic communication between a front of the carrier 62 and a rear of the carrier 62. In this manner, the only fluidic communication between the input vent 24 and the output vent 26 is substantially through the fan 60. In operation, the front 66 of the fan 60 draws ambient air through the input vent 24 that follows the ventilation path through the fan 60 to the rear of the carrier 62 where the ambient air pushes air within the frame housing 12 through the output vent 26.

[0022] With reference now to FIG. 5, a table 100 illustrates operational temperature guidelines of electric components of an eyewear assembly. The temperature guidelines include rows for the first and second displays 18, 20, the camera 48, the SOC 50, and the CPU 30. While IMU 52 is not specifically shown, it should be appreciated that, as expected, the IMU 52 has operational temperature guidelines that are unique to the electronic component. A column labeled Min Operational Temp (°C) can be generally defined as a minimum degree in Celsius where the electronic components begin to potentially exhibit operational problems. A column labeled Min Fan On (°C) can be generally defined as a threshold temperature in Celsius where the control system (e.g., the CPU 30) is configured to activate the fan assembly 22 with the first activation signal. The threshold associated with Min Fan On may be associated with a preventative action to prevent the associated electronic component from reaching a high enough temperature associated with negative operational or structural impacts. A column labeled High Temp Warning (°C) can be generally defined as a temperature in Celsius where the electronic components are close to overheating. A column labeledDegradation (°C) can be generally defined as a temperature in Celsius where the electronic components are still operational but begin to potentially exhibit operational degradation. A column labeled Max Operational Temp (°C) can be generally defined as a maximum temperature in Celsius where the electronic components will still be operational but potentially exhibit significant operational degradation. A column labeled Force Off (°C) can be generally defined as a third threshold temperature or a maximum temperature (e.g., a maximum operating temperature) in Celsius where the electronic components may be damaged. When the maximum temperature is reached, the control system 30 may depower the eyewear assembly 10 to preserve operational life. The forced depowering may be on an electronic component by electronic component basis or applied to the entire eyewear assembly 10 (e.g., a global power off). A column labeled Hysteresis (°C) can be generally defined as a potential difference in Celsius between the actual temperature of the electronic components and the temperature reading by the temperature sensors 28.

[0023] With reference now to FIGS. 1-5, the first threshold temperature associated with the camera 48 is equal to about 45° C. Therefore, if the threshold temperature associated with the camera 48 is reached (e.g., via readings from the temperature sensor 28), the control system (e.g., the CPU 30) may be configured to activate the fan assembly 22 with the first activation signal. The first activation signal may correspond to a first fan speed. In operation, the fan assembly 22 continues to operate at the first fan speed until the temperature sensor 28 associated with the camera 48 is below the first threshold. For example, the fan assembly 22 may continue to operate at the first fan speed until the temperature sensor 28 associated with the camera 48 is below the first threshold by 5° C, 10° C, 15° C, or 20° C, after which, the fan assembly 22 can be deactivated and the temperature sensors 28 can be continually monitored. The same application may be applied to the other electronic components, where after the associated first threshold is reached, the fan assembly 22 is activated until the electronic component is below the first threshold (e.g., by 5° C, 10° C, 15° C, or 20° C).

[0024] With continued reference to FIGS. 1-5, in some instances, for example, based on high usage loads, high ambient temperature, rapid rising internal temperatures, and / or the like, the first fan setting may not reduce the temperature to below the first threshold where the fan assembly 22 can be deactivated. In this manner, the electroniccomponents may each include a second threshold temperature. In some embodiments, at least two of the second threshold temperatures are different. When at least one of the second threshold temperatures is reached, the control system (e.g., the CPU 30) may activate the fan assembly 22 with a second activation signal associated with a second fan speed. The second fan speed may be greater than the first fan speed. In some embodiments, the control system (e.g., the CPU 30) continues to operate the fan assembly 22 at the second fan speed until the electronic component or the temperature sensor 28 associated therewith is below the first threshold temperature (or a second low threshold temperature less than the first threshold temperature) as described previously. In some embodiments, the control system (e.g., the CPU 30) continues to operate the fan assembly 22 at the second fan speed until the electronic component or the temperature sensor 28 associated therewith is equal to the first threshold temperature and / or below the second threshold (e.g., by 5° C, 10° C, 15° C, or 20° C). The second threshold temperature may be associated with temperatures listed in the column labeled High Temp Warning (°C). Each threshold temperature described herein that is associated with increasing the fan speed may be associated with a different threshold temperature that is lower than the threshold temperature that is associated with increasing the fan speed. The control system (e.g., the CPU 30) may monitor via receiving readings from the various temperature sensors 28 and decrease and / or turn off the fan assembly 22 upon the different threshold temperatures being reached. The different fan speeds may include an off state, a low setting, one or more intermediate settings, and a high setting, which may be associated with sequential threshold temperature increases outlined in FIG. 5.

[0025] The eyewear assembly 10 employs multiple temperature sensors 28 to monitor distinct electronic components with different operational temperature guidelines. In this manner, rather than relying on a single temperature reading, the control system (e.g., the CPU 30) can ensure that none of the electronic components overheat. As the different electronic components can experience different operational loads during usage of the eyewear assembly 10 these electronic components can heat at different rates and / or be at different temperatures. Therefore, it should be appreciated that even though the camera 48 is described and shown as having the lowest first temperature threshold, there are scenarios where the camera 48 is below the first temperaturethreshold and another electronic component reaches the associated first temperature threshold based on operational loads. As such, the individual electronic components are maintained and / or driven below the first and second temperature thresholds based on individualized readings from the corresponding temperature sensors 28, preventing operational degradation and damage to the electronic components individually. By monitoring and thermally regulating the electronic components individually, the eyewear assembly 10 as a whole is protected and thermally regulated for maximum operational benefits. Further, by monitoring the temperature of the electronic components individually, the control system (e.g., the CPU 30) may generate warnings if, for example, one of the first display 18 and the second display 20 exhibit differences in temperature above a threshold. Likewise, relationships between the temperatures of the respective electronic components may follow one or more expectant profiles. For example, the CPU 30 may be expected to be within 5° C of a temperature of the displays 18, 20. The CPU 30 may monitor the differences in temperature between components and generate notifications to a user when detected.

[0026] The temperature sensors 28 and / or associated electronic components may be calibrated based on a variety of principles. For example, each or select temperature sensors 28 and / or associated electronic components may be statically calibrated by testing a large sample of temperature sensors and formulating and / or profiling a calibration curve that is hard coded into every temperature sensor 28 and / or associated electronic components. In some implementations, each or select temperature sensors 28 and / or associated electronic components may be calibrated on an assembly or manufacturing line ("MGF line") to determine and / or profile the calibration curve by testing operation over a temperature range. In some implementations, each or select temperature sensors 28 and / or associated electronic components may be calibrated by a runtime calibration process of some temperature sensors 28 using other temperature sensors 28 in the eyewear assembly 10 in circumstances, for example, if the associated electronic components were off for sufficiently long so as to not produce latent heat. The runtime calibration process may be completed, for example, via the control system 30. Further, in some implementations, a combination of the above-described calibration techniques may be utilized. For example, the temperature sensor 28 associated with the control system 30 might use a static or no calibration, but the temperature sensor 28associated with the camera 48 might need an MFG line calibration while the displays 18, 20 use runtime calibration based on the other temperature sensors 28. These calibrations may include a simple calculated offset (e.g., threshold) that is applied to all temperature measurements, or a curve / formula (e.g., profile) that is used to change the offset dynamically. For example, a temperature reading of 25° C may need to be offset by -2° C, while a reading of 55° may need to be offset by +5° C.
