Portable electronic device

The present invention relates to a thermal radiation sensing architecture and a portable electronic device including the same.

With the advancement of technology, portable electronic devices, such as mobile phones, notebook computers, personal digital assistants, etc., are becoming more and more thin and have more and more functions, such as video playback, communication, Internet access, games, and the like. In addition, various portable electronic devices can be installed with large-capacity storage media or memory for users to store messages, letters, files, contacts, etc., so that users do not need to carry a large amount of physical data to achieve a lightweight purpose.

However, lightness generally also represents less expandability and a more limited power supply (ie, the user may not carry a device such as a transformer, a charger, etc., but only the power supplied by the battery to maintain the operation of the portable electronic device). Therefore, researchers in the related art are working on the development of batteries with higher performance and capacity, and on the other hand, reducing unnecessary power consumption of portable electronic devices, for example, when portable electronic devices are used. Turn off the display module during standby.

In addition, the portable portable electronic device is more likely to be lost due to the user's negligence, or the user has to carry it to the body at any time for fear of theft, which is inconvenient. Although there are many anti-theft devices, such as anti-theft locks, it is available for users to prevent theft of portable electronic devices. However, these anti-theft devices generally have a small volume and weight, thus causing a burden on the user to carry. Moreover, the use of these anti-theft devices also allows the thief to know that the user may need to leave a long distance or longer, but it is easy to increase the risk of the portable electronic device being stolen.

In summary, how to effectively utilize limited power and increase the security of the portable electronic device under the principle of lightness is an important issue in the related art.

Therefore, one aspect of the present invention is to provide a thermal radiation sensing architecture that can be applied to a portable electronic device, so that the power of the portable electronic device can be applied more efficiently, and the portable type is also enabled. The safety of electronic devices is further guaranteed.

According to a specific embodiment, the thermal radiation sensing architecture of the present invention comprises a thermal radiation sensing module, a processing module, and a reaction module. The thermal radiation sensing module detects a state of a heat source within a sensing range and generates a first sensing signal according to the state. The processing module is coupled to the thermal radiation sensing module for receiving the first sensing signal. Moreover, the processing module selectively generates a driving signal according to a criterion and the first sensing signal. In addition, the reaction module is coupled to the processing module for receiving the driving signal, and executing a preset program according to the driving signal.

In particular, parameters such as sensing distance, sensing direction, sensing period, sensed temperature range, and thermal radiation wavelength range of the thermal radiation sensing module may be adjusted as appropriate without being limited to any particular parameter.

In a practical application, the preset program may include, but is not limited to, suspending or enabling multimedia playback of the portable electronic device; turning off the display module of the portable electronic device; and driving the portable device Alarm trigger program for electronic devices, etc.

Another aspect of the present invention is to provide a portable electronic device including the aforementioned thermal radiation sensing architecture. In particular, since the portable electronic device includes the thermal radiation sensing architecture, its power application will be more efficient, and it can provide greater convenience to the user.

The advantages and spirit of the present invention will be further understood from the following detailed description of the invention.

The invention discloses a thermal radiation sensing architecture and a portable electronic device including the thermal radiation sensing architecture. In practical applications, the portable electronic device of the present invention may be, but is not limited to, a portable electronic device such as a mobile phone, a personal digital assistant, a notebook computer, and the like.

Referring to FIG. 1 , FIG. 1 is a functional block diagram of a thermal radiation sensing architecture according to an embodiment of the present invention. As shown, the thermal radiation sensing architecture 10 includes a thermal radiation sensing module 100, a processing module 102, and a reaction module 104.

The thermal radiation sensing module 100 can be used to detect the state of a heat source (eg, a user or other person) within a sensing range, and generate a first sensing signal according to the state. In practical applications, the thermal radiation sensing module 100 may be an infrared sensing module or other suitable sensing module.

In addition, the sensing range may be determined by the selected sensing module, or by the manufacturer, designer or even the user of the portable electronic device. For example, when the user places the portable electronic device indoors, the sensing range is set to tens of centimeters or even centimeters in order to prevent the thermal radiation sensing module 100 from being excessively densely operated due to the high density of personnel. Inside. Conversely, when the user places the portable electronic device outdoors, the sensing range can be set to more than one meter, or even several tens of meters.

In a specific embodiment, the thermal radiation sensing module 100 periodically detects the state of the heat source within the sensing range, and when the heat source leaves or enters the sensing range for a predetermined time, the heat The radiation sensing module 100 generates the first sensing signal. For example, if the thermal radiation sensing module 100 senses once every 10 seconds, the thermal radiation sensing module 100 generates the first sensing signal when there is no heat source within the sensing range for ten consecutive times.

In practical applications, other parameters of the thermal radiation sensing module 100 are, for example, but not limited to, such as sensing direction (ie, whether there is a specific direction, angle, etc.), sensing period (eg, every 30 seconds) Measured once), the temperature range sensed (for example, because the sensing is mainly for the human body, so the sensing temperature range is preferably between the absolute temperature of 300K to 315K), the thermal radiation wavelength range (for example, because of the main The parameters are sensed for the human body, so the temperature range of the sensed thermal radiation is preferably between 9.5 μm and 9.8 μm. The parameters can be adjusted as appropriate without being limited to any specific parameters.

The processing module 102 is coupled to the thermal radiation sensing module 100 for receiving the first sensing signal, and the processing module 102 selectively selects the first sensing signal according to a criterion and the first sensing signal. Generate a drive signal. The processing module 104 is coupled to the processing module 102 for receiving the driving signal and executing a preset program according to the driving signal. In practice, the processing module 102 can be integrated with the reaction module 104 in a single processing wafer.

In practical applications, the criteria according to the processing module 102 and the preset program executed by the reaction module 104 may be adjusted, and are not limited to any specific criteria or procedures.

For example, if the portable electronic device is playing a multimedia file, the criterion includes the processing module 102 when the first sensing signal represents the heat source to leave the sensing range (eg, the predetermined time is reached). The driving signal is generated to drive the reaction module 104 to stop playing the multimedia file. Therefore, if the user is viewing the multimedia file and temporarily needs to leave, the criterion can cause the portable electronic device to leave the user (ie, the thermal radiation sensing module 100 does not detect within the sensing range). After the heat source), the multimedia file is automatically stopped to save power.

Of course, in practical applications, the standard can also enable the portable electronic device to automatically shut down the operation of components such as screens after the user leaves, or perform other programs that can save power.

For example, when the portable electronic device is in an alert state, the criterion includes: when the first sensing signal represents the heat source entering the sensing range (eg, reaching the predetermined time), the processing module The drive signal is generated 102 to drive the reaction module 104 to begin timing (eg, positive or countdown). Further, when the reaction module 104 counts a preset threshold and the alert state is not released, the reaction module 104 controls the portable electronic device to issue an alarm.

Therefore, when the user has to leave the portable electronic device for a period of time, the user can set the portable electronic device to enter the alert state. At this time, if the heat radiation sensing module 100 detects that the heat source (which may be the user or another person) enters the sensing range, the heat radiation sensing module 100 may immediately generate a first sensing signal about the situation, or The associated first sensing signal can be generated when the detection is continued for a plurality of times while the heat source is still present.

Then, the processing module 102 drives the reaction module 104 to count according to the criterion. In practice, the reaction module 104 can simultaneously display the chronograph countdown on the screen of the portable electronic device. At this time, if the heat source is the user itself, the alarm state can be released in a preset manner (for example, inputting a specific password; sequentially pressing a specific button, etc.). If the heat source is not the user itself, the alert state cannot be released. Therefore, when the timer reaches a preset threshold, the reaction module 104 controls the portable electronic device to emit an alarm such as sound and light to achieve the anti-theft effect.

In practice, the aforementioned alarm generation procedure can also be divided into multiple stages. For example, when the thermal radiation sensing module 100 detects that the heat source enters the sensing range, the processing module drives the reaction module 104 to emit a flashing warning according to the criterion and starts timing. The reaction module 104 emits an audible alarm when the timing reaches a preset threshold and the alert state is not released.

Referring to FIG. 2, FIG. 2 is a functional block diagram of a portable electronic device according to an embodiment of the present invention. As shown in the figure, the portable electronic device 1 includes the thermal radiation sensing architecture 10 described above, and the thermal radiation sensing architecture 10 also includes a thermal radiation sensing module 100, a processing module 102, and a reaction module 104. The connection relationship of the modules, as well as the actions and functions performed, are as detailed above and will not be described here.

In practice, the thermal radiation sensing module 100 can be disposed on the surface, corners, and the like of the portable electronic device 1 as needed to achieve the best detection effect. In addition, in practical applications, the portable electronic device 1 of the present invention may include other necessary functional units or modules, such as a keyboard, a screen, a Bluetooth module, an infrared module, a global mobile communication system module, Wireless network module, image capture module, recording module, etc.

In particular, in the embodiment, the portable electronic device 1 further includes a motion sensing module 12, such as, but not limited to, a speed sensor, an acceleration sensor, a vibration sensor, and the like. In addition, the motion sensing module 12 is coupled to the processing module 102. The motion sensing module 12 senses the motion state of the portable electronic device 1 and generates a second sensing signal related to the motion state. The processing module 102 receives the first sensing signal from the thermal radiation sensing module 100 and the second sensing signal from the motion sensing module 12, and according to the criterion, the first sensing signal, and the second sensing. The signal selectively generates the drive signal.

In the example where the user has to leave the portable electronic device 1 for a while, the user can also set the portable electronic device 1 to enter the alert state. The difference between the previous embodiment is that the processing module 102 drives the reaction module 104 when the first sensing signal represents the heat source entering the sensing range and the portable electronic device 1 is moved. Timing. Therefore, if the heat source is the user itself, but the user forgets to cancel the alert state, the portable electronic device 1 does not false alarm. It can be seen that, by the arrangement of the motion sensing module 12, the portable electronic device 1 of the present invention can issue an alarm more accurately and avoid false positives.

In practical applications, the portable electronic device 1 of the present invention can also be applied to theft prevention in homes, offices, and the like. For example, the user can place the portable electronic device 1 of the present invention at a door, an office door, or the like, and turn on the alert function. When a dangerous person such as a thief invades a house or an office, the portable electronic device 1 can issue an alarm according to the foregoing mechanism to achieve the purpose of deterrence or notification.

In summary, the thermal radiation sensing architecture of the present invention can be applied to a portable electronic device, so that the power of the portable electronic device can be applied more efficiently, and the portable electronic device is also safe. Sex is further protected. Moreover, the portable electronic device including the thermal radiation sensing structure can further ensure the safety of homes, companies, and the like.
