人體或物質分辨裝置及方法Human body or substance identification device and method

一種人體或物質分辨裝置及方法，更詳而言之，係一種透過電容式及電感式偵測的人體或物質分辨裝置及方法。A human body or substance distinguishing device and method, more specifically, a human body or substance distinguishing device and method through capacitive and inductive detection.

一般而言，手機等通訊行動裝置都需要附加接近感測器以符合人體特定吸收率(SAR)規範。習知技術中通常是使用電容式感測器，電容式感測器係透過感測天線的電容變化量以判斷是否有物體接近。Generally speaking, mobile communication devices such as mobile phones need to be equipped with proximity sensors to comply with the human body specific absorption rate (SAR) standard. Conventional technology generally uses capacitive sensors, which detect the capacitance change of the antenna to determine whether an object is approaching.

然而，由於人體及金屬物質靠近天線都會引起電容改變，因此習知技術的電容式感測器僅能透過持續一段時間(例如10秒以上)監測微小的電容變化量以判斷接近的物體是人體或金屬物質。換言之，習知技術的電容式感測器在效率上及分辨率上的表現都很差，無法滿足需求。因此，如何能提供一種可立即且明確判斷接近的物體是人體或金屬物質的人體或物質分辨裝置及方法，遂成為業界亟待解決的課題。However, since the human body and metal objects approaching the antenna will cause capacitance changes, conventional capacitive sensors can only determine whether the approaching object is a human body or a metal object by monitoring the tiny capacitance change for a period of time (e.g., more than 10 seconds). In other words, conventional capacitive sensors have poor performance in efficiency and resolution and cannot meet the needs. Therefore, how to provide a human body or object identification device and method that can immediately and clearly determine whether the approaching object is a human body or a metal object has become an issue that the industry urgently needs to solve.

以下藉由特定的具體實施例說明本發明之實施方式，熟悉此技藝之人士可由本說明書所揭示之內容輕易地瞭解本發明之其他優點與功效。本發明亦可藉由其他不同的具體實施例加以施行或應用，本說明書中的各項細節亦可基於不同觀點與應用，在不悖離本發明之精神下進行各種修飾與變更。The following is a description of the implementation of the present invention through specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

請參閱圖1，圖1係為本發明第一實施例之人體或物質分辨裝置的功能方塊示意圖。如圖所示，本發明之人體或物質分辨裝置包括電容感測模組10、電感感測模組11以及處理模組12。Please refer to FIG1 , which is a functional block diagram of a human body or substance discrimination device according to a first embodiment of the present invention. As shown in the figure, the human body or substance discrimination device according to the present invention includes acapacitance sensing module 10 , aninductance sensing module 11 and aprocessing module 12 .

電容感測模組10用以透過感測電容變化量以產生第一接近訊號，電感感測模組11用以透過感測電感變化量以產生第二接近訊號，以及處理模組12與電容感測模組10以及電感感測模組11電性連接，並用以接收第一接近訊號以及第二接近訊號，其中，當電容變化量大於或等於第一閾值且電感變化量大於或等於第二閾值時，處理模組12輸出第一判斷訊號，以及當電容變化量大於或等於第一閾值且電感變化量小於第二閾值時，處理模組12輸出第二判斷訊號。Thecapacitance sensing module 10 is used to generate a first proximity signal by sensing a capacitance change, theinductance sensing module 11 is used to generate a second proximity signal by sensing an inductance change, and theprocessing module 12 is electrically connected to thecapacitance sensing module 10 and theinductance sensing module 11, and is used to receive the first proximity signal and the second proximity signal, wherein when the capacitance change is greater than or equal to a first threshold and the inductance change is greater than or equal to a second threshold, theprocessing module 12 outputs a first judgment signal, and when the capacitance change is greater than or equal to the first threshold and the inductance change is less than the second threshold, theprocessing module 12 outputs a second judgment signal.

更詳細而言，當有物體接近時，不論該物體是人體或是金屬物質，電容都會產生變化。因此，當電容感測模組10 所感測到的電容變化量大於或等於第一閾值時，處理模組12可以判斷出有物體接近。另一方面，當接近的物體是人體時，電感不會產生變化，而當接近的物體是金屬物質時，電感會產生變化。因此，配合上述電容變化量的判斷結果，當電感感測模組11 所感測到的電感變化量大於或等於第二閾值時，處理模組12可以進一步判斷出接近的物體是金屬物質，而當電感變化量小於第二閾值時，處理模組12可以進一步判斷出接近的物體是人體。結合電容變化量以及電感變化量兩項判斷條件，處理模組12在判斷出接近的物體是金屬物質時輸出第一判斷訊號，並在判斷出接近的物體是人體時輸出第二判斷訊號。In more detail, when an object approaches, whether the object is a human body or a metal object, the capacitance will change. Therefore, when the capacitance change sensed by thecapacitance sensing module 10 is greater than or equal to the first threshold, theprocessing module 12 can determine that an object is approaching. On the other hand, when the approaching object is a human body, the inductance will not change, and when the approaching object is a metal object, the inductance will change. Therefore, in conjunction with the above-mentioned capacitance change judgment result, when the inductance change sensed by theinductance sensing module 11 is greater than or equal to the second threshold, theprocessing module 12 can further determine that the approaching object is a metal object, and when the inductance change is less than the second threshold, theprocessing module 12 can further determine that the approaching object is a human body. Combining the two judgment conditions of capacitance change and inductance change, theprocessing module 12 outputs a first judgment signal when it judges that the approaching object is a metal material, and outputs a second judgment signal when it judges that the approaching object is a human body.

As shown in the figure, the human body or substance distinguishing device may further include at least oneRF antenna 13a, 13b, 13c. In this embodiment, threeRF antennas 13a, 13b, 13c are used as an example, but it is not limited to this. In other embodiments, there may be more or fewer RF antennas. TheRF antennas 13a, 13b, 13c are connected to thecapacitance sensing module 10 and are used to send RF signals, wherein thecapacitance sensing module 10 is also used to generate a first proximity signal by sensing the capacitance change of theRF antennas 13a, 13b, 13c.

更進一步而言，電容感測模組10係用以透過感測一輻射體的電容變化量以產生第一接近訊號，該輻射體可以是金屬裝飾、邊框或天線等等。在圖2的實施例中，電容感測模組10用以透過感測射頻天線13a、13b、13c的電容變化量以產生第一接近訊號，射頻天線13a、13b、13c可以用以發送射頻訊號。換言之，電容感測模組10可以利用通訊裝置原本具有的射頻天線13a、13b、13c來感測電容變化量，而不需要另外設置輻射體。Furthermore, thecapacitance sensing module 10 is used to generate a first proximity signal by sensing a capacitance change of a radiator, which may be a metal decoration, a frame, or an antenna, etc. In the embodiment of FIG. 2 , thecapacitance sensing module 10 is used to generate a first proximity signal by sensing a capacitance change ofRF antennas 13a, 13b, and 13c, which may be used to send RF signals. In other words, thecapacitance sensing module 10 may utilize theRF antennas 13a, 13b, and 13c originally provided by the communication device to sense capacitance changes, without the need to provide an additional radiator.

Theprocessing module 12 is also used to send a power control signal to theradio frequency module 18 according to the first judgment signal or the second judgment signal, and theradio frequency module 18 is also used to control the power of the radio frequency signal sent by theradio frequency antennas 13a, 13b, 13c according to the power control signal. For example, theprocessing module 12 can send a power control signal to theRF module 18 based on the second judgment signal, that is, when it is judged that a human body is approaching, and theRF module 18 reduces the power of the RF signal sent by theRF antennas 13a, 13b, and 13c according to the power control signal to comply with the SAR specification.

於一實施例中，人體或物質分辨裝置還可包括電感式天線14，電感式天線14與電感感測模組11連接，其中，電感感測模組11還用以透過感測電感式天線14的電感變化量以產生第二接近訊號。電感式天線14可例如是環形天線，但不以此為限。In one embodiment, the human body or material distinguishing device may further include aninductive antenna 14, which is connected to theinductive sensing module 11, wherein theinductive sensing module 11 is further used to generate a second proximity signal by sensing the inductance variation of theinductive antenna 14.

請參閱圖3，圖3係為本發明第三實施例之螢幕及電感式天線的結構示意圖。於一實施例中，人體或物質分辨裝置還可包括螢幕15，螢幕15具有透光保護層150，其中，電感式天線14係環繞設置於透光保護層150之周圍。舉例而言，電容感測模組10與設置通訊裝置的射頻天線13a、13b、13c連接以感測電容變化量，根據射頻天線13a、13b、13c設置的位置可以判斷出接近的物體來自哪個方向。電感式天線14則環繞設置於螢幕15之透光保護層150的周圍，不論接近的物體來自哪個方向都能感測到電感變化量。因此，單一的電感式天線14可以配合設置於通訊裝置周圍的多組射頻天線13a、13b、13c以及電容感測模組10，提供可以判斷出接近的物體的方向以及接近的物體是否為人體之第一判斷訊號及第二判斷訊號。Please refer to FIG3, which is a schematic diagram of the structure of the screen and the inductive antenna of the third embodiment of the present invention. In one embodiment, the human body or material discrimination device may further include ascreen 15, thescreen 15 having a light-transmittingprotective layer 150, wherein theinductive antenna 14 is disposed around the light-transmittingprotective layer 150.

Theinductive antenna 14 is arranged around the transparentprotective layer 150 of thescreen 15, and can sense the inductance change regardless of the direction of the approaching object. Therefore, the singleinductive antenna 14 can cooperate with the multiple sets ofRF antennas 13a, 13b, 13c and thecapacitive sensing module 10 arranged around the communication device to provide a first judgment signal and a second judgment signal that can judge the direction of the approaching object and whether the approaching object is a human body.
