Abstract
Abstract A data processing device (20) for providing data related to the categories of services available at locations along a highway in response to operator input is disclosed. The device includes a memory (54), a keyboard (24) for entering input data identifying a desired service and an origin position into the memory. The input data is compressed before it is stored in the memory (54). The memory stores predetermined data in a compressed form related to the categories of services available at locations along the highway. The device also includes a microprocessor (46) for retrieving from the memory (54) the predetermined data which is a function of the input data. The microprocessor (46) expands the retrieved compressed data into an operator readable form and provides the expanded data to a display (26) for displaying the expanded retrieved data such as restaurants, gas stations, motels, or other services along the highway.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
123 words
A data processing device for providing data related to the categories o£ services available at locations along a highway in response to operator input, the device comprising: a memory; means for entering input data identifying a desired service and an origin position into the memory; means for compressing the input data in the memory; means for storing predetermined data in a compressed format relating to the types of services available at locations along the highway; means for processing the compressed predetermined data and for retrieving from the storing means the compressed predetermined data which is a function of the compressed input data; means for expanding the retrieved compressed predetermined data into an operator readable form; and means for displaying tlhe expanded retrieved data.
Claim 2
Dependent Claim
123 words
A data processing device for providing data related to the categories o£ services available at locations along a highway in response to operator input, the device comprising: a memory; means for entering input data identifying a desired service and an origin position into the memory; means for compressing the input data in the memory; means for storing predetermined data in a compressed format relating to the types of services available at locations along the highway; means for processing the compressed predetermined data and for retrieving from the storing means the compressed predetermined data which is a function of the compressed input data; means for expanding the retrieved compressed predetermined data into an operator readable form; and means for displaying tlhe expanded retrieved data.
Claim 3
Dependent Claim
29 words
A device according to claim 1 wherein the retrieved compressed data includes a coded number and the expanding means comprises means for converting the coded number into a name.
Claim 4
Dependent Claim
25 words
A device according to claim 1 or 2 wherein the means for retrieving retrieves data relating to the closest desired service to the origin position.
Claim 5
Dependent Claim
25 words
A device according to claim 3 wherein the means for retrieving alternatively retrieves data relating to the next closest desired service to the origin position.
Claim 6
Dependent Claim
45 words
A device according to claim 3 or 4 comprising means for calculating distance data relating to the distance between the closest desired service or the next closest desired service and the origin position, and wherein the means for displaying selectively displays the calculated distance data.
Claim 7
Independent Claim
76 words
A device according to any preceding claim wherein the entering means includes: means for entering input data relating to a country, a highway, a direction, a location, and category; and wherein the storing means comprises: a country register for storing the entered country; a highway register for storing the entered highway; a direction register for storing the entered direction; a location register for storing the entered location; and a category register for storing the entered category.
Claim 8
Dependent Claim
184 words
A device according to claim 1 for providing data related to the categories of services available at locations along a highway crossing a boundary of first and second contiguous geographical areas in response to operator input, wherein: the entering means includes means for entering in the memory input data identifying a desired service and an origin position along the highway in the first geographical areas; the storing means includes means for storing first and second tables of predetermined data of the categories of services available at selected locations in the first and second geographical areas, respectively, along the highway; and further comprising: means for determining whether the closest desired service is located in the first or second geographical area; means, responsive to the means for determining, for selecting the first table if the closest desired service is located in the first geographical area and for selecting the second table if the closest desired service is located in the second geographical area; and wherein the retrieving means includes means for retrieving from the selected table predetermined data which is a function of the input data.
Claim 9
Dependent Claim
33 words
A device according to claim 7 wherein the determining means comprises means for storing a cumulated distance representative of the distance between the origin location and the boundary of the first geographical area.
Claim 10
Dependent Claim
74 words
A device according to claim 7 wherein the storing means stores a third table of the categories of services available at selected locations in a third geographical area contiguous to the first or second geographical areas, and the determining means determines whether the closest desired service is located in a third geographical area, and wherein the selecting means selects the third table if the closest desired service is located in the third geographical area.
Claim 11
Dependent Claim
46 words
A device according to claim 7, 8 or 9 comprising: means for compressing the input data stored in the memory; wherein the predetermined data in the storing means is in a compressed form; and means for expanding the retrieved compressed data into an operator readable form.
