Abstract

Weather forecasting apparatus for producing a visual indication of a weather forecast in response to supplied information, with such supplied information including current weather conditions, current wind speed and wind direction, geographical region information, and season of the year information. The apparatus includes a keyboard upon which such information may be entered, encoders for encoding the information, a display section for lighting one of a plurality of lamps to indicate forecasted weather, and read only memory elements having a plurality of memory locations for storing weather forecast data and for supplying the weather forecast data to the display section from memory locations specified by the coded data. Temperature and relative humidity detecting circuitry may also be included in the apparatus for providing a visual indication of the current temperature and current relative humidity.

Claims

1. Apparatus for producing weather forecast information in response to supplied information, said apparatus comprising

a housing dimensioned so that it can be held in the hand,

keyboard means disposed in said housing and including

a first plurality of manually operable keys upon which current weather information may be entered by operation of keys appropriately designated and representing different types of weather,

a second plurality of manually operable keys upon which current wind speed information may be entered by operation of keys appropriately designated and representing different wind speeds,

a third plurality of manually operable keys upon which current wind direction information may be entered by operation of keys appropriately designated and representing different wind directions,

a fourth plurality of manually operable keys upon which current season of the year information may be entered by operation of keys appropriately designated and representing diffferent seasons of the year,

first address means responsive to the operation of said first plurality of keys for producing a first partial address,

second address means responsive to the operation of said second plurality of keys for producing a second partial address,

third address means responsive to the operation of said third plurality of keys for producing a third partial address,

fourth address means responsive to the operation of said fourth plurality of keys for producing a fourth partial address,

display means carried by the housing for producing a visual display of weather forecast information in response to receipt of weather forecast data,

read only memory means having a plurality of memory locations for storing weather forecast data and for supplying weather forecast data to said display means from memory locations each specified by an input address, and

means for combining the partial addresses to produce an input address for application to said read only memory to identify a location in the memory from which weather forecast data is to be read.

2. Apparatus as in claim 1 wherein said keyboard means further includes a multiplicity of region keys, each of which is appropriately designated and represents a different geographical region, and wherein said read only memory means includes a multiplicity of read only memories, each of which stores weather forecast data for a different one of said geographical regions and each of which is enabled to supply weather forecast data when a corresponding one of said region keys is operated.

3. Apparatus as in claim 2

wherein said keyboard means further includes a fifth plurality of manually operable forecast mode keys, each of which represents a different future time period over which the desired weather forecast information is to apply,

said apparatus further including fifth address means responsive to the operation of said fifth plurality of keys for producing a fifth partial address for application to said combining means.

4. Apparatus as in claim 1 wherein said display means comprises

a plurality of light-emitting devices, each representing a different weather forecast condition, for emitting light in response to activating signals, and

decoder means for selectively applying activating signals to said light-emitting devices in response to receipt of said weather forecast data.

5. Apparatus as in claim 1 further comprising

second and third read only memory means, each having a plurality of memory locations for storing second and third weather forecast data respectively, and, when enabled, for supplying such data to said display means from memory locations specified by input addresses,

wherein said first read only memory means is adapted to supply weather forecast data to said display means when enabled,

means disposed in said housing for detecting atmospheric pressure and for periodically storing an indication of the detected pressure,

means coupled to said detecting means for producing first, second and third signals indicating that the atmospheric pressure is respectively steady, rising or falling,

means for applying said first signal to enable said first read only memory means,

means for applying said second signal to enable said second read only memory means, and

means for applying said third signal to enable said third read only memory means.

6. Apparatus as in claim 5 further comprising

first display means responsive to said first signal for producing a visual indication that the atmospheric pressure is steady,

second display means responsive to said second signal for producing a visual indication that the atmospheric pressure is rising, and

third display means responsive to said third signal for producing a visual indication that the atmospheric pressure is falling.

7. Apparatus as in claim 1 further comprising

means for producing a temperature signal whose value is proportional to current temperature, and

display means responsive to said temperature signal for producing a visual indication of the current temperature represented by the value of the temperature signal.

8. Apparatus as in claim 1 further comprising

means for producing a humidity signal whose value is proportional to current relative humidity, and

display means responsive to said humidity signal for producing a visual indication of the current relative humidity represented by the value of the humidity signal.

9. A method for producing weather forecast information comprising

storing weather forecast data in a read only memory,

providing a keyboard means having a first, second, third and fourth plurality of keys,

operating a first plurality of keys appropriately designated and representing different types of weather to thereby specify current weather information,

operating a second plurality of keys appropriately designated and representing different wind speeds to thereby specify the current wind speed,

operating a third plurality of keys appropriately designated and representing different wind direction information to thereby specify the current wind direction,

operating a fourth plurality of keys appropriately designated and representing different seasons of the year to thereby specify the current season of the year,

producing a first partial address in response to the operation of said first plurality of keys,

producing a second partial address in response to operation of said second plurality of keys,

producing a third partial address in response to operation of said third plurality of keys,

producing a fourth partial address in response to operation of said fourth plurality of keys,

combining said first, second, third and fourth partial addresses to produce an input address which indentifies a location in the read only memory,

applying the input address to the read only memory to read therefrom the weather forecast data stored in the location identified by the input address, and

producing a visual display of weather forecast information in response to the reading of the weather forecast data.
