    • An iontophoresis system includes a transdermal patch for placement against the skin of a patient and a controller electrically connected to the patch. The patch includes an anode and cathode electrode, and holds an electrolyte and a medication. The controller includes a DC-DC converter circuit which generates an output voltage that is provided to the anode electrode. The controller also includes an adjustable current regulator circuit. The current regulator circuit is coupled to the cathode electrode and is adjustable to provide a desired current flow through the electrodes and the skin of the patient. The DC-DC converter circuit is responsive to the voltage drop across the electrodes and adjusts its output voltage in response to this voltage drop and changes in the impedance of the patient's skin.
    • 离子电渗系统包括用于放置在患者皮肤上的透皮贴片和与贴片电连接的控制器。 贴片包括阳极和阴极电极,并且保持电解质和药物。 控制器包括DC-DC转换器电路,其生成提供给阳极电极的输出电压。 该控制器还包括一个可调电流调节器电路。 电流调节器电路耦合到阴极电极并且可调节以提供通过患者的电极和皮肤的期望的电流。 DC-DC转换器电路响应于电极两端的电压降并响应于该电压降和患者皮肤阻抗的变化来调节其输出电压。

    • A system for correcting an output device for the effects reflected ambient illumination comprises an output device, a calibration memory, a reflectivity memory, a system memory, a processor, an input device, a video card, a color display memory, and a reflection device of known reflectivity. The color display memory stores a first graphical interface and a second graphical interface. The first graphical interface displays a range of intensities of outputs that the display device can generate. The second graphical interface displays a range of hues that the display device can generate. The reflection device defines an aperture. The reflection device is compared to the first graphical interface and the second graphical interface by viewing the interfaces through the aperture. The present invention includes a method for compensating an output device for reflected ambient illumination. The system receives a first input of an intensity of the first graphical interface that appears to match the ambient illumination reflected from the reflection device; the system then receives a second input of a hue of the second graphical interface that appears to match the ambient illumination reflected from the reflection device. The system determines the intensity and hue of the ambient illumination reflected from the output device by matching the intensity and hue of the ambient illumination reflected from the reflection device with the output of the output device. The system then adjusts the outputs of the output device to compensate for the reflected ambient illumination.
    • 用于校正反射环境照明的效果的输出装置的系统包括输出装置,校准存储器,反射率存储器,系统存储器,处理器,输入装置,视频卡,彩色显示存储器和反射装置 已知的反射率。 彩色显示存储器存储第一图形界面和第二图形界面。 第一个图形界面显示显示设备可以产生的输出强度范围。 第二个图形界面显示显示设备可以生成的色调范围。 反射装置限定孔径。 通过观察通过孔径的界面将反射装置与第一图形界面和第二图形界面进行比较。 本发明包括用于补偿反射环境照明的输出装置的方法。 该系统接收第一图形界面的强度的第一输入,该第一图形界面似乎与反射装置反射的环境照明相匹配; 系统然后接收第二图形界面的色调的第二输入,其显示为与反射设备反射的环境照明相匹配。 该系统通过将从反射装置反射的环境照明的强度和色调与输出装置的输出相匹配来确定从输出装置反射的环境照明的强度和色调。 然后系统调整输出设备的输出以补偿反射的环境照明。
