摘要： A digital transmitter (10) with an analog sensor (18) uses an integrating analog-to-digital (A/D) converter (20) to digitize the analog signal from the sensor (18). The A/D converter (20) produces a digital output which is a continuous, non-rezeroed integrated average of the analog signal, so that the integrated average of the digital output over time does not contain inherent quantization errors. A microcomputer system (22) digitally filters the signal from the A/D converter (20), and then uses the digitally filtered signal to produce the transmitter output signal. By varying the response time of the digital filter (22A), the response time and resolution of the transmitter (10) can be varied.

摘要： An apparatus (10) optically detects the position of a movable element (31) through the use of six discrete tracks (14, 16, 18, 20, 22, 24). Each of the tracks (14, 16, 18, 20, 22, 24) is formed on a glass substrate and has a preselected pattern of optically transmissive and opaque sections arranged thereon. A light source (48) and optical sensors (34, 36, 38, 40, 42, 44) are associated with each of the tracks such that the light is either blocked or passed to the optical sensors (34, 36, 38, 40, 42, 44) respectively responsive to the opaque and transmissive sections. Five of the tracks (14, 16, 18, 20, 22) correspond to form a five bit absolute gray code pattern indicative of the position of the movable element (31). The sixth remaining track (24) has alternately opaque and transmissive sections arranged to form an incremental track where the count of the number of opaque and transmissive sections travelling past an initial set point is maintained in memory and corresponds to an incremental position within each of the absolute positions. The microprocessor base controller limits the number of incremental transitions within an absolute position to thirty-two or two to the fifth power. The thirty-two possible positions, when used as the lower five bits of a ten bit binary word, where the upper five bits come from the five absolute tracks, forms a ten bit pseudo-gray code indicative of the position of the movable element (31) and is highly accurate without the necessity of ten absolute tracks and the cumbersome packaging associated therewith.

摘要： Information related to the position of a control member (28) of a vehicle (12) is required for control of power delivered to the vehicle motors (22, 24). Available linear position encoders are expensive and prone to damage in an industrial environment. The instant apparatus (10) provides a simple and durable linear position encoder (10) having a piston (40) adapted to move within a housing (30). A plurality of sensors (68a-d) are each positioned along a different housing pathway (66a-d) and a plurality of sensible members (72a-d) are each positioned along a different piston pathway (54a-d). In response to movement of the piston (40) within the housing (30) the sensors (68a-d) deliver respective position signals to an electric circuit means (78), which, in turn, delivers respective coded digital signals to a vehicle controller (26). The apparatus (10) is digital in design and is of simple, rugged, and inexpensive construction.

摘要： An absolute decoder comprises a measuring scale (1) with at least one track and a plurality of analog sensors (47, 48) for such track. The output of each sensor is modulated by the track to generate a plurality of cyclic non-sinusoidal multiphase analog signals from the sensors indicative of the relative position of the sensors and the measuring scale. The multiphase signals are converted to digital form (50, 51) and conditionally added or subtracted (58) to obtain an output that increases linearly in proportion to the position of the sensors relative to the measuring scale.

摘要： A threshold detection circuit (30) for improving the output of a two-wire transmitter (10) is disclosed. The transmitter (10) comprises a sensing means (14) which has a sensor (16) responsive to a parameter (12) to be sensed by the transmitter (10) and an excitation means (18) which provides an excitation output to excite the sensor (16). A threshold detection circuit (30) is coupled to the sensor output and provides a detector output representative of an undesired change in excitation output which can produce a sensor output which is not substantially representative of the sensed parameter (12). An output means (24) is coupled to the sensor output and detector output and provides the transmitter output as a function of the sensor output and detector output. A distinctive transmitter output representative of an undesired change in excitation output thus detected is provided, thereby improving the transmitter output.

摘要： The substance of the invention consists in separate coding of the movement values of an object according to higher and lower code orders, the higher orders being coded in cyclic code by division of the range of the movement values into n parts which are each coded through their own scale multiplier. The code of the lower orders is shifted in relation to the code of the higher orders and the movement code is reproduced by forming, by means of reading elements (2, 3) of electric signals corresponding to the lower and the higher code orders. The electric signals corresponding to the lower orders are converted by means of a forming unit (4) into four electric signals which are equal in amplitude and are mutually 90 DEG out of phase. The electric signals corresponding to the lower orders are interpolated and the numerical code of the lower orders is formed by means of a comparator unit (6) and a logic processor (7). The cyclic code of the higher orders is converted into binary code by means of a comparator unit (8), a converter (9) and a logic processor (10). The shifted codes of the lower and higher orders are converted into binary code by means of a converter (11).
摘要翻译：本发明的实质在于根据较高和较低的编码顺序对对象的移动值进行单独的编码，较高的顺序通过将运动值的范围分成n个部分，循环代码中被编码，每个部分通过它们被编码自己的比例乘数。较低级的代码相对于较高次序的代码移位，并且通过利用对应于较低和较高代码次序的电信号的读取元件（2,3）形成移动代码。对应于较低级的电信号通过形成单元（4）转换成振幅相等且相位相差90°的四个电信号。通过比较器单元（6）和逻辑处理器（7），对与低阶对应的电信号进行内插并形成低阶数字码。较高阶的循环码通过比较器单元（8），转换器（9）和逻辑处理器（10）转换成二进制码。通过转换器（11）将较低和较高阶的移位代码转换成二进制代码。

摘要： A position sensor has a detector fixed to a first body, the detector having sensitive elements defining a track (10) of such elements. A scale being e.g. the optical image of a part of a second body, is caused to impinge on the detector. The scale has a track (6) of indicia (i.e. a bar pattern) and the sensitive elements of the track (10) of the detector detect their overlapping with a corresponding one or more of the indicia and generate an output depending on that overlapping. The indicia of the track (6) of indicia define two patterns (A, B) arranged in a plurality of successive sections (8). One pattern (A) is fixed for all sections (8) and the other pattern (B) varies according to a predetermined rule (e.g. cyclically) from section (8) to section (8). The track (10) of the detector detects a length of the track (6) of indicia corresponding approximately to the length of a section (8), as a result, the output of the detector can be processed to determine the relative positions of the first and second bodies, from detection of the relative position of the detector and the fixed pattern together with the relationship between the two patterns.

摘要： A positional encoder which provides absolute position information from a single code track. A chain code track is positioned on a code disk to supply position words of N consecutive bits, each position word being unique and corresponding to a different position of the code disk. Means are provided for detecting the elements of the chain code as the code disk is rotated with respect to a fixed point. The position data are accumulated in the order received and N consecutive bits are examined to determine the position to which the bits correspond.
