Abstract

A portable electronic language translation apparatus including a keyboard for receiving operator entered words in one language and a memory such as a programmable read only memory controlled by a microprocessor for comparing and analyzing each letter or group of letters of the keyboard entered word to determine whether the corresponding word in a second language is stored within the memory. If the corresponding word is so stored, it is displayed for viewing by the operator. The disclosed circuit permits automatic translation from one language to another without specification of the input language by the operator.

Claims

1. Apparatus for electrically retrieving any selected one of a plurality of intelligence symbols from one of a pair of sets of intelligence symbols in accordance with a predetermined translation between the sets, comprising

(a) input means for generating an electrical signal indicative of the selected intelligence symbol;

(b) symbol storage means for storing a readable signal representative of each intelligence symbol in each said set at a separate address unique to each said intelligence symbol in each said set and for storing an address signal in association with each said readable signal in at least one said set for identifying the address of the corresponding intelligence symbol in the other set as required by the predetermined symbol translation;

(c) comparison means connected with said input means and said symbol storage means for sequentially comparing said electrical signal generated by said input means with said readable signals with which address signals are associated and for reading out the address signal associated with the readable signal which corresponds to said electrical signal generated by said input means; and

(d) symbol read out and display means connected with said symbol storage means and said comparison means for visually displaying the selected intelligence symbol and for reading out and displaying the intelligence symbol represented by the readable signal stored at the address read out by said comparison means.

2. Apparatus as defined in claim 1, wherein said symbol storage means is a programmable read only memory and said comparison means is a microprocessor.

3. Apparatus as defined in claim 2, wherein said input means includes a random access memory for temporarily storing electrical signals indicative of the selected intelligence symbol.

wherein said input means is a keyboard mounted on said portable housing;

said symbol storage means and said comparison means are mounted within said portable housing; and

said symbol read out and display means includes an electronic alphanumeric display mounted on the exterior of said portable housing.

5. Apparatus as defined in claim 4, wherein said programmable read only memory is a replaceable plug-in unit, whereby the permanently stored addressable signals may be changed selectively by replacing the plug-in unit with another plug-in unit having a different pair of sets of intelligence symbols.

6. Apparatus as defined in claim 1, wherein said comparison means includes set limiting means for limiting the sequential comparison to only addressable signals representative of intelligence symbols contained within a single set.

7. Apparatus as defined in claim 1, wherein said symbol storage means stores an address signal in association with each said readable signal in both sets for identifying the address of the corresponding intelligence symbol in the other set as required by the predetermined symbol translation.

14. Apparatus as defined in claim 1, wherein the intelligence symbols further include word use identification and wherein said symbol storage means further stores use signals indicative of word use in association with each readable signal indicative of the corresponding word and wherein said comparison means include word use comparing means for comparing the word use identification associated with said selected intelligence symbol with the word use signals stored in said symbol storage means, whereby the word use identification information can be used to uniquely identify the corresponding intelligence symbol stored within said symbol storage means should more than one language word having the same letters and sequence of letters be stored in said symbol storage means.

8. Apparatus for electrically retrieving an intelligence symbol from one of a pair of sets of intelligence symbols in accordance with a predetermined translation between the sets, comprising:

(a) input means for generating electrical signals indicative of the selected integlligence symbol;

(b) symbol storage means for permanently storing at predetermined addresses readable signals representative of the intelligence symbols in said sets and for storing address signals in association with said readable signals in each set for identifying the address of the corresponding intelligence symbol in the other set as required by the predetermined symbol translation;

(c) comparison means connected with said input means and said symbol storage means for sequentially comparing said electrical signals generated by said input means with said readable signals and for reading out said address signals associated with the readable signal which corresponds to said electrical signals generated by said input means; and

(d) symbol read out and display means connected with said symbol storage means and said comparison means for visually displaying the selected intelligence symbol and for reading out and displaying the intelligence symbol represented by the readable signals stored at the address read out by said comparison means, said symbol read out and display means includes set indicating means for visually indicating the set of which each displayed intelligence symbol is a member.

9. Apparatus as defined in claim 8, wherein each set is a language and each intelligence symbol is a word and wherein the predetermined symbol translation constitutes a translation of meaning from one language to the other and further wherein said symbol read out and display means includes a first electronic alphanumeric display means for visually displaying the selected word in one language and the word having equivalent meaning in the other language.

10. Apparatus as defined in claim 9, wherein said set indicating means includes a second electronic alphanumeric display means for visually displaying the language of which the respective words displayed by said first electronic alphanumeric display means are a part.

11. Apparatus as defined in claim 10, wherein each said intelligence symbol includes a word and a word use identification and wherein said input means includes a keyboard input means for receiving manual input indicative of both word and word use for conversion into corresponding electrical signals and further, wherein said symbol read out and display means includes word use indicating means for visually indicating the word use input received by said keyboard means.

12. Apparatus for electrically translating a multi-letter word selected from one language into a corresponding word in another language, comprising:

(a) input means for generating electrical signals indicative of the letters in the selected word;

(b) symbol storage means for permanently storing at predetermined addresses readable signals representative of corresponding words in both languages, said readable signals including letter signals representative of each letter in each word and for storing address signals in association with said readable signals representative of words in one language for identifying the address of the corresponding word in the other language;

(c) comparison means connected with said input means and said symbol storage means for comparing said electrical signals generated by said input means with said readable signals and for reading out said address signals associated with the readable signals which correspond to said electrical signals generated by said input means;

(d) symbol read out and display means connected with said symbol storage means and said comparison means for visually displaying the selected word and for reading out and displaying the word represented by the readable signals stored at the address read out by said comparison means.

13. Apparatus as defined in claim 12, wherein said comparison means includes letter comparing means for:

(a) comparing the electrical signals generated by said input means representative of the first letter of the selected word with the letter signals representative of the first letter of each word stored in said symbol storage means,

(b) comparing the electrical signals representative of the second letter of said selected word with the letter signals representative of the second letter of each word stored in said symbol storage means which was detected to have a first letter identical to the first letter of said selected word, and

(c) continuing to compare the electrical signals representative of the successive letters in the selected word with the letter signals representative of the corresponding letters in each word stored in said symbol storage means until only one word stored in said symbol storage means is identified by said comparison means as having the same letters and the same sequence of letters as said selected word.
