The present invention generally relates to an electrical timer which automatically controls the activation and deactivation of electrical devices, such as light fixtures, appliances and the like based on the time of sunrise and/or sunset for a particular geographic location. In this regard, the sunrise and/or sunset times for a multitude of different geographic locations is collected and stored in the timer's memory in association with the relevant geographic location. Each geographic location is specified in memory by geographic indicia, such as postal zip code or telephone area code, of its location (e.g., latitude and longitude). The timer of the present invention is programmed to automatically activate and/or deactivate the device to which it is coupled (e.g., lights, appliances, etc.) at the sunset and/or sunrise times stored in memory for each date that is specified in memory.

A global time reckoning system simultaneously indicates local time and global time. The global time reckoning system can be practiced with standard clock timer drivers, including electromechanical and digital clock motors, in combination with a novel global time system clock face to allow a user to reckon time locally or anywhere on the globe without time zone conversion calculations. The global time system clock face has multiple time scales, at least one of which is driven by the clock drive in cooperation with an hour indicator (e.g., an hour hand). The global time system clock face simultaneously displays global time (relative to any location on the globe) and local time. Additionally, the global time reckoning system, with the appropriate clock timer driver is adaptable to indicate a number of other global time related information, including sunrise/sunset, days of the week, lunar phase and solstices/equinoxes.

A method for tracking solar panels includes the steps (a) beginning a tracking cycle substantially at sunrise with adjacent tilting panels all horizontal, (b) tilting the adjacent panels in unison in a first angular direction toward the rising sun at a tilt rate that just avoids shading of adjacent panels, (c) reversing direction of panel tilt at a point that the panels reach either a maximum tilt limited by mechanical design, or the panel surfaces are orthogonal to the rising sun, (d) tilting the adjacent panels in a second angular direction, following movement of the sun and keeping the surface of the panels at right angles to the sun's position, until a point is reached that shadowing is imminent from the angle of the setting sun, and (e) reversing direction of panel tilt again to the first angular direction, adjusting tilt as the sun sets to avoid shading until the panels are again horizontal.

An illumination system verifies whether one or more aspects of an output signal provided by a photosensitive transducer fall within a threshold of an expected value for the aspect. The aspect may include a sunrise time, a sunset time, a dawn time, a dusk time, a solar noon time, a solar midnight time, or similar. Upon verification the illumination system uses a microcontroller to adjust one or more output parameters of a solid-state light source responsive to the output signal provided by the photosensitive transducer. Where verification is not possible, the illumination system uses the microcontroller to adjust one or more output parameters of the solid-state light source responsive to a schedule.

A method and apparatus for accessing an one of a plurality of highly localized weather broadcasts based on the reception by a weather forecast service of call related information (e.g., Caller ID information) relating to an incoming call. A server associated with the weather service includes separate weather forecasts each based on call related information, e.g., an area code and/or exchange number. The highly localized weather forecast may be downloaded in analog or digital form, and may be played as received by a caller or stored for later playback. An off-line automatic dialer and record control module establishes a telephone call to a weather server at a predetermined time, e.g., just before sunrise, and automatically activates the downloading and storage of the weather forecast without further instruction required by the user. This allows the provision of a highly localized weather broadcast system which is capable of forecast resolution at least down to the locality of a particular exchange in a particular area code, while at the same time having the capability of being commonly located at a single telephone number. The highly localized weather forecasts may be accessed real-time for immediate audible play, or off-line by downloading a particularly chosen weather forecast while the customer premises equipment is off-line. The weather forecast may be downloaded in audible form and recorded at the customer premises equipment, or with the use of modems may be digitally downloaded to storage in the customer premises equipment for later playback.

A method and device that controls one or more apparatus in relation to the expected time of sunrise and sunset at the location of the apparatus. The operator enters a geographic location identifier, such as a zip code or telephone area code, and the controller computes the expected time of sunrise and sunset at the corresponding geographic location. The controller is configured to translate the entered geographic location code into the offset times, based upon the latitude and longitude of the location. The controller is able to either directly retrieve stored time offsets or it retrieves the latitude and longitude that corresponds to the entered geographic location code and determines the time offset from that latitude and longitude.
