图14示意性地示例了第一电极和地之间的阻抗作为致动部件(例如用户的手指、手或任何其它身体部分)距输入设备的距离的函数。 FIG 14 schematically illustrates the function of the impedance between the first electrode and as the actuating member (e.g. a user's finger, hand or any other body part) from the input device distance. 为此解释的目的,假定利用有固定频率的电压来驱动第一电极。 The explanation for this purpose, assume that a first electrode driven by the voltage of a fixed frequency. 在图14中,距离沿水平轴从左至右降低。 In FIG 14, reducing the distance along the horizontal axis from left to right. 如果致动部件远离设备,其阻抗最大。 If the actuator member away from the device, the impedance maximum. 随着致动部件接近(此时不与设备接触),电极和地之间的电容增高,使得阻抗降低。 As the actuator member closest (this time not in contact with the device), increasing the capacitance between the electrode and ground, such that the impedance is lowered. 随着致动部件变得甚至更近,其逐渐压到设备上,由此使得第一和第二电极进行接触。 As the actuator member becomes even closer, which is gradually pressed onto the device, whereby the first and second electrode contact. 现在电容基本保持恒定,但是第一和第二电极之间的电阻现在随传感器上的压力增高而降低。 Now the capacitor remains substantially constant, the resistance between the first electrode and the second current decreases with increased pressure on the sensor. 结果,阻抗朝最小值降低。 As a result, lower impedance toward a minimum. 应当注意,当致动部件与承载膜将接触时,设备有利地从电容探测模式(第二操作模式)切换到电阻探测模式(第一操作模式)。 It should be noted that when the actuating member in contact with the carrier film, the device advantageously switches from the capacitance detection mode (second operation mode) to the resistance detection mode (first operation mode).

图15示出了根据本发明的第二主要方面的数据输入设备10,,包括膜类型构造的电容接近度和压力传感器12'。 Figure 15 shows a capacitive proximity ,, 10 and the pressure sensor 12 includes a membrane of the type of configuration data input device of the second main aspect of the present invention '. 电容接近度和压力传感器12,包括第一和第二承载膜16'、 18'形式的第一和第二承载层,所述承载膜由诸如例如PET、 PEN、 PI等的基本柔性的电绝缘材料制成。 Capacitive proximity sensor 12 and a pressure, comprising a first and a second carrier film 16 ', 18' in the form of first and second carrier layer of the carrier film is made of a flexible electrically insulating such as a basic example PET, PEN, PI or the like made of a material. 间隔物20,夹置于第一和第二承载膜16'、 18'之间,使得它们保持彼此分开。 Spacer 20, interposed the first and second carrier films 16 ', 18' between, so that they remain separated from each other. 间隔物20,也能够由基本柔性的电绝缘材料制成,例如双面胶。 The spacer 20 can be made of a substantially flexible, electrically insulating material, for example, double-sided tape. 间隔物20,在其中设置有界定压力传感器10'的有效区的开口14,。 Spacer 20, defining an opening in which a pressure sensor active region 10 '14 ,. 在有效区14,中,第一承载箔16,在其指向第二承载膜18'的侧上承载第一电容器电极22,,而第二承载箔18,在其指向第一承载膜16,的侧上承载第二电容器电极24'。 14, the first carrier foil 16, carries a first capacitor electrode 22 on the second side of the carrier film 18 'which points in the active region 18 ,, and a second carrier foil, at which point the first carrier film 16, the carrying a second capacitor electrode 24 'on the upper side. 第一和第二电容器电极22'、 24'由直接分别施加在第一和第二承载膜16'、 18'上的导电材料(例如银墨)形成。 A first and a second capacitor electrode 22 ', 24' are applied directly formed from the first and second carrier films 16 ', 18' of conductive material (e.g., silver ink) on. 第二电容器电极在其上形成电绝缘材料(电介质,例如PET、 PEN、 PI等)的层26'。 The second capacitor electrode layer is formed of electrically insulating material (dielectric, e.g. PET, PEN, PI, etc.) thereon 26 '.

图15的右手侧示出了由引线30'、 32'连接至第一和第二电容器电极22'、 24'的控制电路28'。 The right-hand side of FIG. 15 shows a control circuit 28 is connected by a lead 30 ', 32' to the first and second capacitor electrodes 22 ', 24' '. 控制电路28,包括微处理器、专用集成电路(ASIC)或可编程芯片,配置为至少在第一和第二操作模式中操作。 The control circuit 28 comprising a microprocessor, application specific integrated circuit (ASIC) or programmable chips, configured to operate in at least first and second modes of operation. 在第二操作模式时,控制电路确定表示第一电容器电极和地之间的电容的参量,而在第一操作模式时,控制电路确定表示第一电容器电极和第二电容器电极之间的电容的参量。 In the second mode of operation, the control circuit determines the quantity represents the capacitance between the first capacitor electrode and the ground, and when the first operation mode, the control circuit determines represents the capacitance between the first capacitor electrode and the second capacitor electrode Parameter.

第二操作模式与感测要感测的物体的接近度关联,要感测的物体例如是用户的手指34'。 The second mode of operation associated with the sensing to sense the proximity of the measured object, an object to be sensed, for example, a user's finger 34 '. 在第二操作模式中,控制电路将第一和第二电极基本保持在相同的电位,使得在第一和第二电极之间基本消除了电场。 In the second mode of operation, the control circuit the first and second electrodes is maintained at substantially the same potential, so that between the first electrode and the second electric field is substantially eliminated. 第二电极24'从而用作用在第一电极22'的驱动屏蔽,且后者的敏感性被从第二电极24'引导开。 The second electrode 24 'so that a first electrode 22 acting' driving shield, the sensitivity and the latter is opened and the second electrode 24 'from the guide. 如果将振荡电压施加于第一电容器电极,则建立了至地的振荡电场。 If the oscillating voltage applied to the first capacitor electrode, it is the establishment of an oscillating electric field to ground. 要感测的物体更改了第一电容器电极和地之间的电容,其由控制电路28'感测。 The object to be sensed changes the capacitance between the first capacitor electrode and the ground, its' sense by the control circuit 28. 应当注意,在第二操作模式中,探测物体的接近度不需要物体触碰或接触接近度和压力传感器12'。 It should be noted that, in the second mode of operation, detecting proximity of an object does not require touching or proximity objects, and a pressure sensor 12 '.

第一操作模式与感测由某种制动器施加于传感器上的压力关联,制动器诸如例如是用户的手指或触针。 Sensing a first operating mode and the brake is applied by a certain pressure on the sensor associated with, for example, such as the brake user's finger or stylus. 在第一操作模式中,控制电路基本上确定由第一和第二电容器电极22'、 24'形成的电容器的电容。 In a first mode of operation, the control circuit is substantially determined by the capacitance of the first capacitor and the second electrodes 22 ', 24' form a capacitor. 电容器的电容取决于其电极之间的距离是公知的。 Capacitance of the capacitor depends on the distance between the electrodes which is well known. 在示例的情况下,第一和第二电容器电极之间的距离随由用户施加于压力传感器上的压力的增高而降低。 In the case of the example, the distance between the first and second capacitor electrode with a pressure applied to the pressure sensor is increased by the user is reduced. 结果,电容器电极之间的电容增高,其由控制电路28,探测。 As a result, increasing the capacitance between the capacitor electrode 28, is detected by the control circuit.

图16示出了图15的接近度和压力传感器的变形。 Figure 16 shows a modification of a pressure sensor and proximity 15 of FIG. 其构造相同,除第一电容器电极22'和第二电容器电极24'那样在其上形成电绝缘材料层26,外。 Configured the same, in addition to the first capacitor electrode 22 'and the second capacitor electrode 24' is formed as an electrically insulating material layer 26 on its outside. 这些本领域技术人员将理解,图案化一个电绝缘材料26,容许在第一操作模式中剪裁接近度和压力传感器的响应。 Those skilled in the art will appreciate that a patterned electrically insulating material 26, allowing in a first mode of operation in response to proximity of the cut and the pressure sensor. 只要电绝缘材料彼此间隔开(即用于由用户施加的低压力),则图案对传感器没有显著影响。 As long as an electrically insulating material spaced from one another (i.e., a low pressure applied by the user), the pattern had no significant influence on the sensor. 然而,随着压力增高,电绝缘层获得接触并形成接触面。 However, as the pressure increased, and the electrically insulating layer is formed in contact with a contact surface is obtained. 图案化的绝缘层导致第一和第二电极之间的最小距离在接触面上变化。 Patterning the insulating layer leads to a minimum distance between the first electrode and the second contact surface changes. 因此,电容增高不同于绝缘层一致的情况。 Therefore, the capacitance increased unlike the case of the same insulating layer. 图17中示出了图案化的绝缘层的范例。 FIG 17 shows an example of the patterned insulating layer.

在图18a中,用户的手指434'轻轻触碰第一承载膜416'。 In Figure 18a, the user's finger 434 'gently touch a first carrier film 416'. 所施加的压力不足以引起键的区域中的第一承载膜416,的显著弯曲。 The applied pressure is insufficient to cause a first region of the key in the carrier film 416, is significantly bent. 通过对电容器电极422'的每个电极确定表示此电极422'和地之间的电容耦合的参量来探测用户的手指434'的位置。 By the capacitor electrode 422 'is determined for each electrode indicates an electrode 422' variable capacitive coupling between the ground and to detect the position of the user's finger 434 & apos ;. 位置可以例如作为第一电容器电极422'的位置的质心来计算,被利用对应的表示电容的参量进行加权。 Position may be, for example, the centroid position of the electrode 422 'is calculated as a first capacitor, the capacitance being represented by the corresponding amount of weighting parameters. 例如当用户利用触垫412'来控制光标时(例如在器具的显示器上),第二操作模式是适合的。 For example when the user contact pad 412 'is used to control a cursor (e.g., on a display appliance), the second mode of operation is suitable.

在图18b中,用户压下第一承载膜416',使得其弯曲到间隔物420'的开口414,中,并且对应的第一和第二电容器电极422,、 424,之间的距离降低。 In Figure 18b, the user depresses a first carrier film 416 ', so that it is bent into a spacer 420' of the opening 414, and the first and second capacitor electrodes 422 corresponding to the distance between ,, 424, is reduced. 这使得这些电容器电极之间的电容上升,这能够在触垫412,的第一操作模式中被探测。 This makes the capacitance increase between the capacitor electrodes, which can be detected on the touch pad 412, a first mode of operation. 第一操作模式因此与触垫412'的键的致动关联,致动例如是通过用户的手指434'或触针。 A first mode of operation and thus contact pad 412 'is associated with key actuation, for example actuated by a user's finger 434' or stylus.

操作中,第一和第二操作模式交替执行,即触垫412'或多或少周期地从第二操作模式切换至第一模式,并相反地。 In operation, the first and second modes of operation are alternately performed, i.e., contact pad 412 'more or less periodically switching from the first mode to the second mode of operation, and conversely. 应当注意,在第一操作模式中,触垫不需要对每个键确定表示电容的参量。 It should be noted that, in a first mode of operation, the contact pads do not need to determine the parameters showing the capacitance for each key. 实际上,当触垫412,操作在第二操作模式中时,如果仅针对已经探测到用户的手指434,的位置的邻近区域中的该键或该些键确定后者,则其被认为是有利的。 Indeed, when the contact pads 412, operating in the second mode of operation, only if the latter is determined for the adjacent areas has been detected position of the user's finger 434, in which the plurality of keys or key, it is considered to be advantageous. 图19a和19b示出了具有键区功能性的替代触垫512'的横截面。 Figures 19a and 19b illustrate an alternative functional keypad contact pads 512 'cross-section. 触垫512,包括第一承载膜516,、第二承载膜518,以及间隔物521',间隔物夹置于第一和第二承载膜516'、 518'之间,使得将它们隔开。 Contact pad 512, 516 comprises a first carrier film ,, the second carrier film 518, and a spacer 521 ', the spacer interposed first and second carrier films 516', between 518 ', such that they are spaced apart. 间隔物521'由电绝缘的可压縮的泡沫材料制成,例如聚氨酯泡沫等。 The spacer 521 'is made of electrically insulating material, a compressible foam, such as polyurethane foam or the like. 第一和第二承载膜516,、 518,具有施加于面向间隔物521,的表面上的电容器电极522'、 524,。 First and second carrier films 516 ,, 518, is applied to the capacitor electrode having a surface facing the spacer 521, the 522 ', 524 ,. 每个第一电容器电极522'布置在第一承载膜上,相对于间隔物521',与第二承载膜上的第二电容器电极524'相对。 Each of the first capacitor electrode 522 'arranged in the first carrier film, with respect to the spacer 521', the second capacitor electrode and the second carrier film 524 'opposite. 每对相对的第一和第二电容器电极规定触垫512'的键。 Each pair of opposing first and second predetermined capacitor electrode contact pads 512 'of the key. 后者还包括控制电路(未示出),其在第二操作模式中确定表示第一电容器电极522'的单独的电极和地之间的电容的参量,而在第一操作模式中确定表示第一电容器电极522'的单独的电极和第二电容器电极524'的关联的电极之间的电容的参量。 The latter further comprises a control circuit (not shown), which is determined in the second mode of operation represents the capacitance of the variable capacitor between the first electrode 522 'and the individual electrodes, whereas in the first mode of operation is determined represents variable capacitance between the electrodes associated with a capacitor electrode 522 'and the individual electrodes of the second capacitor electrode 524 & apos ;.

在图19a中,用户的手指534'轻轻触碰第一承载膜516'。 In Figure 19a, the user's finger 534 'gently touch a first carrier film 516'. 所施加的压力不足以引起键的区域中的第一承载膜516'的显著弯曲。 The applied pressure is insufficient to cause a first region of the key in the carrier film 516 'is significantly bent. 通过对第一电容器电极522'的每个电极确定表示此电极522'和地之间的电容耦合的参量来探测用户的手指534'的位置。 Through the first capacitor electrode 522 'is determined for each electrode indicates an electrode 522' variable capacitive coupling between the ground and to detect the position of the user's finger 534 & apos ;. 如先前的范例中,位置可以例如作为第一电容器电极522'的位置的质心来计算,被利用对应的表示电容的参量进行加权。 Calculated as in the previous example, the centroid position may be for example, as a first capacitor electrode 522 'position is weighted using a parameter represented by a corresponding capacitance. 例如当用户利用触垫512'来控制光标时(例如在器具的显示器上),第二操作模式是适合的。 For example when the user contact pad 512 'is used to control a cursor (e.g., on a display appliance), the second mode of operation is suitable.

在图19b中,用户压在第一承载膜516,上,使得压縮其下的间隔物521,, 由此降低第一和第二电容器电极522'、 524,对之间的距离。 In Figure 19b, the user presses a first carrier film 516, the spacer 521 such that the lower compression ,, thereby reducing the first and second capacitor electrodes 522 ', 524, the distance between the pair. 这使得这些电容器电极之间的电容上升,这能够在触垫512,的第一操作模式中被探测。 This makes the capacitance increase between the capacitor electrodes, which can be detected on the touch pad 512, a first mode of operation. 第一操作模式因此与触垫512'的键的致动关联,致动例如是通过用户的手指534'或触针。 A first mode of operation and thus contact pad 512 'is associated with key actuation, for example actuated by a user's finger 534' or stylus.
