Abstract: A measurement device and method that in one aspect determines and displays percentile information relating to growth indices, such as BMI, weight-for-length, and weight-for-height, based on a subject's age and gender. The device and method may also provide classification information, such as whether the percentile information is considered to be, for example, below normal, normal, above normal, or far above normal. The device and method may additionally indicate, for example, the normal range of the subject's weight based on the subject's height, the subject's height based on the subject's weight and the normal range of BMI based on the subject's age and gender. In still another aspect, the device and method may indicate predictive values of the subject's future weight, height, BMI or head circumference based on the subject's present measurement values and growth percentiles.

Abstract: Apparatus and methods for employing electrical properties of water to indicate the level of filtered water in a filtered water container. The container is fitted with a hopper that holds unfiltered water. The hopper is fitted at its base with a removable and replaceable filter cartridge. Water is filtered by draining through the filter medium contained in the filter cartridge into the lower portion of the container. The water level in the filtered water container is monitored by means of one or more water level detector strips in the hopper or in the lower portion of the filtered water container. The detector strips are in electrical communication with a detection circuit and a control unit. The control unit uses the detection strips to monitor water level and uses such data to track filtered water consumption and to determine when the filter cartridge should be replaced.
