Abstract: A method of assessing the quality of an retinal image (such as a fundus image) includes selecting at least one region of interest within a retinal image corresponding to a particular structure of the eye (e.g. the optic disc or the macula), and a quality score is calculated in respect of the, or each, region-of-interest. Each region of interest is typically one associated with pathology, as the optic disc and the macula are. Optionally, a quality score may be calculated also in respect of the eye as a whole (i.e. over the entire image, if the entire image corresponds to the retina).

Abstract: A flow battery system has an electrolyte storage tank, a flow battery, and a box-type flow battery system. A circular pipe I and a circular pipe II are provided in the electrolyte storage tank; the circular pipe II is communicated with an electrolyte return opening; the circular pipe I is communicated with an electrolyte delivery outlet; the annular perimeter of the circular pipe I is not equal to the annular perimeter of the circular pipe II. The multi-layer circular pipe structure in the storage tank reduces the flowing dead zone of electrolyte in the storage tank. Moreover, The reduction in the longitudinal distance between the electrolyte delivery outlet and the electrolyte return opening also reduced the problem of SOC lag so that the SOC monitoring accuracy of the flow battery is improved.

Abstract: A voltage supply circuit for an LCD driver employs two voltage dividers. A low current voltage divider includes resistive elements having a high resistance, thus providing a bias voltage with a low current. A high current voltage divider includes resistive elements having low resistances, thus providing a bias voltage with a high current. The high current voltage divider provides bias voltage levels with high current at the beginning of each time phase change. Thus, the liquid crystal display receives a high current when updating the bias voltage levels on the LCD, thereby producing a fast settling time. When the bias voltage levels are held constant, however, only the low current voltage divider provides the bias voltage levels to reduce power consumption. A halt mode prevents the liquid crystal display and driver from consuming any power by disconnecting both voltage dividers from the voltage source when in sleep mode.
