摘要： This optoelectronic, finger-operated keyboard for use in industrial measurement equipment is designed to achieve an optimum signal-to-noise ratio and minimize the drop in the intensity of the infrared emitters during the service life of the measurement equipment. The keys for generating respective associated operation signals (n1, n2, n3) have an infrared-transmitting cover (1), one infrared emitter (3) per key disposed at the inside (12) of the cover and emitting light collimated virtually perpendicular thereto, one infrared detector (4) adjacent to each infrared emitter which is separated from the latter by a shield (5) opaque to infrared and is pointed at the cover, said infrared detector being located within the main radiation range of the infrared light emitted by the infrared emitter and scattered at a finger (2) but outside the infrared light reflected from the outside and/or inside of the cover. An operating circuit (8) comprises a separate control and detection circuit (15, 25, 35) for each key which generates current-control pulses (si1, si2, si3) with a mark/space ratio less than 1:1 for feeding the infrared emitter (13, 23, 33), and a scanning circuit (18) common to all keys which switches a current switch (19) connecting all control and detection circuits (15, 25, 35) to one terminal (SN) of a supply-voltage source into a conducting state.

摘要： A reflection-type photoelectric proximity detector and switch is capable of detecting the incremental and binary proximity of a finger through several layers of glass, cancelling out extraneous reflections and stray sources of radiation. The circuitry includes a modulated infrared emitter, an infrared detector, an optical barrier, an infrared filter, a bandpass filter, a signal rectifier, a biasing circuit to remove unwanted detected modulated signal, an amplifier, an incremental proximity output, a comparator, a detection reference, and a binary proximity detect output. In one embodiment a multitude of photoelectric proximity switches are installed on the inside of a store window, detect finger proximity from outside the window, and control electric appliances inside the store window. From outside the window, a user can select what is displayed inside the window.

摘要： An optical keyboard includes a plurality of photosensors arranged in an X-Y coordinate system where a plurality of rows represent a plurality of X-axes and a plurality of columns represent a plurality of Y-axes. Each sensor represents input to data processing means. When a beam of light is cast onto a photosensor, the photosensor is actuated to transmit a coded signal to a microprocessor board. The microprocessor board scans the array of photosensors row by row sequentially to identify the column position of an actuated photosensor. The input received from the scanning operation is converted to data and transmitted through either a serial or parallel interface to a computer. Interface circuitry converts the data to a form readable by the computer. Thus, by selectively moving a light source to desired photosensors, specific information can be transmitted to a computer for printout or for operation of other devices remotely controlled by the computer to permit the computer to be operated by individuals unable to perform manual keyboard operations.
摘要翻译：光学键盘包括布置在X-Y坐标系中的多个光电传感器，其中多行表示多个X轴，多列表示多个Y轴。每个传感器代表对数据处理装置的输入。当光束投射到光传感器上时，光电传感器被致动以将编码信号发送到微处理器板。微处理器板依次扫描光电传感器阵列以识别激活的光电传感器的列位置。从扫描操作接收的输入被转换为数据，并通过串行或并行接口传输到计算机。接口电路将数据转换成计算机可读的形式。因此，通过选择性地将光源移动到期望的光电传感器，可以将特定信息发送到计算机以打印输出或用于由计算机远程控制的其他设备的操作，以允许计算机由不能执行手动键盘操作的个人操作。

摘要： A data entry system includes a keyboard which includes a panel of chemically toughened, laminated glass. The upper surface of the panel has a plurality of key areas respectively representative of different keys, and a plurality of LEDs are respectively positioned opposite the key areas adjacent the lower surface of the panel. Each LED has a photodiode associated therewith, each photodiode being arranged to receive infra-red light emitted by the associated LED, transmitted through the glass panel and reflected back from an operator's finger placed on the respective key area to operate that key. Output signals are produced in response to infra-red light reflected back to the photodiodes, and, in response to these signals, a microprocessor produces an output indicative of an operated key. The data entry system is suitable for use in a through-the-wall automated teller machine.

摘要： The invention provides a method for operation of a touch input device (2) comprising a touch input area. The method comprises the steps of : (i) detecting a touch or near-touch of an object (32, 37, 38) on or near said touch input area; (ii) determining a parameter indicative of the size and/or shape of said object; (iii) comparing said parameter with at least one predetermined value; and (iv) enabling an operational state of said touch input device in response to said comparison. The parameter may be compared with one or more threshold values which delimit the operational state of the input device. Such operational states include a sleep mode or active mode, the use of a full QWERTY or reduced keyboard, translation or rotation of graphical elements, etc. The method is particularly suitable for differentiating between a touch by a stylus (32) or touch by a finger (37).

摘要： A user-configurable control device particularly suitable for household devices such as remote control transmitters (Fig. 1, Fig. 3) includes a variety of function control elements (10, 110, 210) in the form of keys. Each control element (110) has a unique pattern of projections (120) in an operative alignment with an array of membrane switches (125) within the control device. The control device includes a front panel (104) for receiving a desired set of control elements that is selected by the consumer. Each control element (110) has a pair of tabs (116) that securely retains the element on the control panel (104), but which also allows removal if desired. The pattern of switch contacts (125) closed upon actuation of the corresponding control element (110) via the particular pattern of projections (120) thereof determines the function that is performed. Alternately, each control element (210, 232) may have a unique pattern of apertures (218, 238) in operative alignment with an array of optical sensors (224) within the control device.

摘要： Arrangement for keyboards of the optoelectronic type which exhibit a surface area (1) in the form of a prism (16) divided up into fields (17). Each of the fiels is allocated an individual control function. They are intended to be contacted at the respective control function by a surface such as the surface of a finger tip. This causes a deflection of light, which is produced in the field, in relation to the luminous flux in the prism when there is no contact with the surface. The variation in luminous flux is supplied to a light-detecting sensor (19) by means of which an adequate command signal is generated. A control means (20) is so arranged as to produce a signal specific to each field (17) and capable of being selected from the signals from other fields. A single element or a small number of elements is/are provided as the sensor element (19). A signal processing means is also so arranged as to select the signal received from the sensor element in accordance with the specific signal characteristics for each of the fields, and as to transmit an adequate command signal for each field in accordance with said selection.
