摘要： PROBLEM TO BE SOLVED: To accurately determine the position and/or speed of a movable element. SOLUTION: The measuring device for determining the position (x) and/or the speed (v) is provided with: a scale 1 having marks 2, 3 and 25 arranged at spacings (l 1 -l 9 ) from one another; and a scanning head 4, with the scale 1 and the scanning head 4 being arranged for movement relative to one another along a movement direction 5. The scanning head 4 is constructed to determine a first spacing a 1 of the scanning head in the movement direction 5 relative to the first mark 2, and a second spacing a 2 of the scanning head in the movement direction 5 relative to the second mark 3, with the position (x) and/or the speed (v) being determined by the measuring device on the basis of the first spacing a 1 and the second spacing a 2 .

摘要： PURPOSE: To obtain an excellent reproduction output corresponding to the pattern of a magnetic recording signal by varying a bias magnetic field for each element in a magnetic head.
CONSTITUTION: A bias line 5 is formed slantingly to an array of elements 1A, so the relation between the distance (a) from an element 1A facing the low-order digit bits 4a of a Gray code recorded magnetically on a magnetic medium to the bias line 5 and the distance (b) from an element 1D facing the high-order digit bits 4b to the bias line 5 is set to a>b corresponding to the size (length) of respective bits 4a and 4b. A bias magnetic field applied to the element 1A facing the low-order digit bits 4a is smaller than a bias magnetic field applied to the element 1D facing the high-order digit bits 4b. Consequently, the respective suitable bias magnetic fields varies according to respective bit signals on characteristic curves of respective magneto-resistance elements according to variation of a sense magnetic field and bias points where reproduction outputs of the respective bit signals are reproduced faithfully are formed through the bias line 5, so that excellent outputs of both low-order and high-order digit bits are obtained.

摘要翻译：目的：通过改变磁头中的每个元件的偏置磁场来获得对应于磁记录信号的图案的优异的再现输出。构成：偏置线5倾斜地形成为元件1A的阵列，因此从磁性介质上记录到磁性介质上的格雷码的低位数位4a的元件1A的距离（a）与偏置线5和来自面向高阶数位4b到偏置线5的元件1D的距离（b）被设置为对应于各个位4a和4b的大小（长度）的> b。施加到面向低位数位4a的元件1A的偏置磁场小于施加到面向高位数位4b的元件1D的偏置磁场。因此，相应的适当的偏置磁场根据感测磁场的变化和各个位信号的再现输出忠实地通过偏置形成的偏置点根据各个磁阻元件的特性曲线上的相应位信号而变化线5，从而获得低阶和高位数位的优异输出。

摘要： An optical code disc includes a fine track which provides a high resolution signal, at least one V scan natural binary track synchronized to the fine track by lead and lag detectors, and Gray code tracks which provide the most significant bits of the digital output of the encoder system. The number of circuit elements in the multiplier circuitry associated with the fine track are reduced by means of a quadrant switching technique whereby the sinusoidal inputs to the multiplier are repeated through each quadrant of the fine track cycle. The V scan and Gray code tracks are optically multiplexed to reduce the number of leads from the optical detector. The use of both V scan and Gray code tracks minimizes the number of detectors required in the system while maintaining large detector signals from each track. The V scan and Gray code outputs are synchronized by the use of an overlapping bit.

摘要： Information related to the rotary angular position of a steerable wheel portion of an electric vehicle is required for proper control of the vehicle and especially for differential control of the driven wheels of the vehicle. Available rotary position encoders are expensive, prone to damage in an industrial environment, and sensitive to misalignment between the encoder components. The instant apparatus provides a simple and durable rotary position encoder having a plurality of sensors positioned on a first mounting member and a plurality of sensible members positioned on a second mounting member. The apparatus is digital in design and the particular location and arrangement of the sensors and sensible members advantageously compensates for overtravel and misalignment of the encoder components.

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