    • An apparatus and method of analyzing an aqueous solution, as may be implemented with a hand-held portable electronic device (10). A test pad (32) responsive in color to a characteristic of an aqueous solution is interrogated by the device by measuring, in a plurality of wavelength ranges, intensity values of a test light as reflected off of the test strip. The intensity values may be expressed as values relative to intensities reflected off of white and black calibration surfaces. A relationship among the intensity values for the various wavelength ranges is developed through an algorithm that provides a ratio value that is responsive to the characteristic of the aqueous solution and that is non-responsive to absolute intensity values of the reflected light. The test pad may be supported on an opaque and non-reflective substrate (28) that cooperates with an opaque edge portion (14E) of a test element placement member (14B) and associated side walls (14W) of the device to minimize the impingement of ambient light onto the test pad during interrogation.
    • 一种分析水溶液的装置和方法,可以用手持便携式电子设备(10)实现。 通过在多个波长范围内测量从测试条反射的测试光的强度值,通过测量器件询问在颜色上与水溶液的特性有关的测试垫(32)。 强度值可以表示为相对于白色和黑色校准表面反射的强度的值。 通过提供响应于水溶液的特性并且不响应于反射光的绝对强度值的比值的算法来开发各种波长范围的强度值之间的关系。 测试垫可以被支撑在不透明和非反射衬底(28)上,该衬底与设备的测试元件放置构件(14B)的不透明边缘部分(14E)和相关联的侧壁(14W)配合, 在询问期间最小化环境光在测试垫上的碰撞。

    • A tissue ablation system is described that generates a uniform avascular plane of coagulated tissue to aid in the bloodless or near-bloodless resection of various biological tissues from a variety of organs. The tissue ablation system includes an energy director guide and two or more sets of bipolar energy directors. The energy director guide includes a series of channels that configure the energy directors to provide approximately uniform power distribution or current density through a target tissue volume or plane. The spacing among the channels of the energy director guide varies according to the total number of energy directors received in the energy director guide so that relative spacing among the center-most channels is largest and relative spacing among the end-most channels is smallest. The energy director guide secures a selected position of each of the energy directors in the target tissue volume.
    • 描述了组织消融系统,其产生凝固组织的均匀的无血管平面,以帮助来自各种器官的各种生物组织的无血或近无血的切除。 组织消融系统包括能量导向器引导件和两组或多组双极能量引导器。 能量导向器引导件包括一系列通道,其配置能量引导器以通过目标组织体积或平面提供近似均匀的功率分布或电流密度。 能量导向器引导件的通道之间的间隔根据能量导向器引导器中接收到的能量引导器的总数而变化,使得最中心的通道之间的相对间隔最大,并且最终通道之间的相对间隔最小。 能量导向器引导件将每个能量引导器的选定位置固定在目标组织体积中。
