摘要： Impedance measurement of battery cells within a battery system comprising at least one string of battery cells is accomplished by dividing each of the strings into at least two portions. A loading current for measurement purposes is only imposed on a portion of one of the strings at any given time and battery cell voltage measurements are made only within this string portion.

摘要： Apparatus for measuring the total internal resistance of a multicell battery having positive and negative terminals employs a first transistor device having an input and an output and having mutually exclusive conductive and non-conductive electric states. An arrangement of resistances is connected in series with the device to form a network. The network is connected between the positive and negative terminals. An operational amplifier has an output connected to the input of the device and first and second inputs. The first input is connected to the network at a point connected to both of the device and the arrangement. A square wave signal alternating between a positive voltage and ground on alternate half cycles is applied to the second input. The device is in the conductive state when the alternating voltage is positive and is in the non-conductive state when the alternating voltage is at ground. The network conducts no current when the device is in the non-conductive state and conducts a current of constant value when the device is in the conductive state. The voltage appearing between the terminals as a result of the current in the network is monotonically related to the internal resistance of the battery.
摘要翻译：用于测量具有正和负端子的多电池电池的总内部电阻的装置采用具有输入和输出并具有相互排斥的导电和非导电电状态的第一晶体管器件。电阻的布置与设备串联连接以形成网络。网络连接在正极和负极之间。运算放大器具有连接到设备的输入和第一和第二输入的输出。第一输入端连接到与设备和设备两者相连的点。将交替的半周期的正电压和地之间交替的方波信号施加到第二输入。当交流电压为正时，器件处于导通状态，并且当交流电压接地时处于非导通状态。当器件处于非导通状态时，网络不会导通电流，并在器件处于导通状态时导通恒定电流。作为网络中的电流的结果，在端子之间出现的电压与电池的内部电阻单调相关。

摘要： A sewing machine is disclosed wherein the positional coordinates for successive stitch penetrations are stored in a memory having addressable locations corresponding to a plurality of operator selectable patterns. Means are provided for operator initiation of an override command to selectively alter the operation of the feed and bight actuators to an amount of motion different from that dictated by the stored pattern information. An operator influenced control provides a digital signal corresponding to a desired alteration value. Override memory locations are provided for storing bight and feed actuator motion alteration values. These locations are addressed in accordance with the selected pattern and the digital override signal provided by the operator. The alteration values are utilized for control of the appropriate feed and bight actuators.

摘要： A sewing machine is disclosed wherein the positional coordinates for successive stitch penetrations are stored in a memory having addressable locations corresponding to a plurality of operator selectable patterns, one of which is a buttonhole pattern. The buttonhole pattern includes two parallel rows of zig-zag stitches forming a pair of buttonhole side bars, the inner stitches of the side bars defining a cutting space therebetween and the outer stitches of the side bars defining the width of the buttonhole pattern. Means are provided for operator initiation of an override command to selectively alter the operation of the bight actuator to selectively control the position of only the inner side bar stitches so as to selectively vary the width of the cutting space while maintaining constant the overall buttonhole pattern width.

摘要： A controller to permit a sewing machine operator to control a sewing machine drive motor from control members located in close proximity to the needle bar. Means are provided to permit the operator to select the sewing speed and the needle stop position prior to commencing the sewing process. The operator may thereafter control the sewing process by light finger pressure applied to the control members without attention being distracted from the work feeding area. The operator may suspend the sewing process by removing pressure from the control members. The sewing machine will thereafter stop with the needle bar in the selected position. A reset circuit is provided to prevent the operator from unintentionally actuating the sewing machine drive motor.

摘要： A method of forming an eyelet end buttonhole pattern having two spaced apart rows of zig zag stitches joined at one end by a generally circular pattern of zig zag stitches includes first forming a single stitch in the eyelet end, then feeding the fabric in the forward direction until the stitch forming point is at the other end of the buttonhole pattern from where the initial stitch was placed. A side bar is then stitched, beginning in reverse, proceeding around the eyelet end, then in a forward direction to the other end of the pattern. The feeding is then reversed and the stitching retraces the buttonhole pattern in the opposite direction. Barring stitches are then sewn, to close and finish the buttonhole pattern with a square end.

摘要： A sewing machine is disclosed in which electromechanical actuators are incorporated. By selectively supplying power to position the electromechanical actuators, the stitch forming instrumentalities of the sewing machine may be operatively controlled. In order to reduce heat dissipation within the sewing machine under abnormal conditions where the actuators are locked for long periods of time, the sewing machine main drive motor motion is monitored. After a predetermined period of inactivity of the sewing machine main drive motor, the power which can be supplied to the actuators is limited.
