Optical Method and Apparatus for Determining Fertility Status

An optical method of determining a woman's fertility status is provided, wherein an optical system (20) has a sample receiving surface (29) and an eyepiece (28), such that the sample can be viewed in focus through the optical system (20) without altering the distance between the eyepiece (28) and the sample receiving surface (29) using ambient-light illumination. A sample of a bodily fluid from a female is deposited at the sample receiving surface (29) of the optical system (20) and dried. The dried sample is then inspected using the optical system (20) and the appearance of the dried sample is correlated with a reference.

Integrated Alert System

Contemplated alert systems provide increased functionality and interactive operation by use of subsystems that are coupled between the GUI/rules engine and the alert devices, wherein the subsystems provide for bidirectional flow of information. Therefore, in one aspect, the GUI displays functional and operational parameters of associated alert devices in real time and thus allows an administrator rule building without knowledge of installed devices. In another aspect, as the alert system displays and controls all associated alert device via the GUI, contemplated alert systems allow activation of multiple and distinct alert devices using a single user interface. Viewed from another perspective, contingency- and area-specific alerts can be triggered from the GUI using only point-and-click action.

Lifesaver Personal Alert and Notification Device

Systems and methods of alert and notification transmission are contemplated in which a low-range transceiver provides an alert/notification to a plurality of users having a wearable transceiver. Most typically, the low-range transceiver (a) is located in a wide area notification zone and a trigger device provides a signal from a wide area notification device to the low-range transceiver and (b) is used to also provide non-emergency notifications to the wearable transceivers. It should be appreciated that transmission of the emergency signal using the low-range transceiver is automatic, while transmission of the non-emergency notifications requires manual user input.

Irrigation Controller Using Estimated Solar Radiation

An irrigation controller (200) receives temperature data, and at least partly derives an estimated solar radiation value from the temperature data. A regression model stored in a memory (220) of the irrigation controller (200) operates upon a data point from the estimated solar radiation to estimate an evapotranspiration rate, which is used to affect an irrigation schedule executed by the controller (200). The regression model is preferably based upon a comparison of historical ETo values against corresponding historical environmental values, with the data advantageously spanning a time period of at least two days, and more preferably at least one month. Data from one or more environmental factors may also be used, including especially estimated solar radiation, temperature, wind speed, hnmidity, and soil moisture, and so forth. Values relating the environmental factor(s) may enter the controller from a local sensor (240), a distal signal source, or both.

Configurations and Methods for Wave Energy Extraction

A wave energy harvester includes an element that converts forward and/or backward movement of water in a wave passing the harvester into upward and/or downward movement to thereby increase the vertical amplitude of the harvester relative to the sea floor. In most preferred aspects, the element is a hydrofoil that is coupled to the harvester. Further preferred aspects include those in which part of, or the entire harvester has a neutral buoyancy, and where energy is extracted from the downwards movement of the neutrally buoyant part after a wave has lifted that part.
