Abstract
Abstract A Ghebleh bearing indicator apparatus for providing a user with a displayed indication of the relative bearing between his current position and a destination, such as Mecca, includes a keyboard and display. A microprocessor processes selected stored latitude/longitude information for one of a plurality of cities along with information from an included electronic digital compass to calculate and display the bearing to Mecca on a compass rose. The apparatus includes a preprogrammed list of up to eight cities which, in one operational mode, allows an unsophisticated user to select a location merely by pressing a single key on the keyboard. In a second mode, a plurality of countries and associated cities is scrolled on the screen to permit highlighting and selection by the user.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
119 words
A bearing indicator apparatus for indicating a bearing and orientation between the location of the apparatus and a desired location, the apparatus comprising: a portable housing; a keyboard mounted in said housing for inputting positional information; a display mounted on said housing; an electronic compass contained within said housing to provide information concerning the current orientation of said apparatus relative to the magnetic North pole; a microprocessor contained within said housing and connected to said keyboard, said display and said electronic compass, for calculating the bearing to and orientation of the desired location from positional information input from said keyboard, orientation information from said compass and the location of a desired location and displays the bearing on said display.
Claim 2
Dependent Claim
119 words
A bearing indicator apparatus for indicating a bearing and orientation between the location of the apparatus and a desired location, the apparatus comprising: a portable housing; a keyboard mounted in said housing for inputting positional information; a display mounted on said housing; an electronic compass contained within said housing to provide information concerning the current orientation of said apparatus relative to the magnetic North pole; a microprocessor contained within said housing and connected to said keyboard, said display and said electronic compass, for calculating the bearing to and orientation of the desired location from positional information input from said keyboard, orientation information from said compass and the location of a desired location and displays the bearing on said display.
Claim 3
Dependent Claim
14 words
The apparatus of claim 1 wherein said positional information is in a latitude/longitude format.
Claim 4
Dependent Claim
21 words
