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 touch sensitive control panel is disclosed which is constructed of a support surface and a graphic display member secured thereto. The support surface has regions of conductive material deposited thereon and the graphic display member has functional indicia printed thereon, there being a layer of adhesive intermediate the graphic display member and the support surface to secure the graphic display member to the support surface with the functional indicia in registration with the conductive material regions. The graphic display member and the adhesive layer form a dielectric medium between the conductive material and a body portion of an operator touching the front surface of the graphic display member. An improved method for manufacturing such a touch panel is also disclosed.

摘要： An optical buttonhole switching arrangement in which the movement of reflective means carried on a moveable buttonhole foot are sensed as the foot is moved by the fabric feeding movement of a feed dog against the garment being sewn. The foot includes adjustable optical targets whose movement may be sensed by a photosensor carried on the sewing head. The spacing of the optical targets may be manually adjusted to accommodate buttons of different sizes. The photosensor is connected to an electronic circuit whose output may be used to control the retrieval of buttonhole stitching information from an electronic memory.

摘要： A light detector is supported in a mask box which extends into the cavity accommodating the looptaker with an edge of the surface adjacent the looptaker and upstream to the air currents generated by the looptaker closer to the looptaker than an edge downstream in order to discourage lint build up on the adjacent surface. A light source is fashioned with a lens projecting into the cavity accommodating the looptaker similarly to discourage lint build up.
