Abstract

Method and portable processor for storing and comparing sets of personal data relating to personal preferences and personality. First and second portable processing units each include a processor, a memory, an input device, a display device, and a connector. The owner of a portable processor can enter personal data via the input device of the portable processor in response to a questionnaire. The owner of that portable processor may then meet another person having a similar or identical portable processor storing that person'"'"'s personal data. The two persons can interconnect the two portable processors by means of the connectors. Each portable processor transmits its data to the other and compares its stored data with corresponding data received from the other portable processor. Stored algorithms in each portable processor operate on the compared data to compute a score representing the degree of personal compatibility of the two persons and display the score by means of the respective display devices. In one embodiment of the invention, a first set of data is stored in a low power memory of the first processor and a second set of data is then entered via a keyboard on the first processor into the first portable processor. The program stored in the first processor is further capable of comparing the first set of data with the second set of data and displaying a resulting score without the necessity of connecting a second processor to the first processor.

Claims

1. A first portable computing device for comparing a first set of data stored in said first portable computing device with a second set of data stored in a second computing device to which said first portable computing device can be temporarily coupled, said first portable computing device comprising in combination:

(a) coupling means for temporarily coupling said first portable computing device to said second computing device to effect transmission of data of said first set from said first portable computing device to said second computing device and to effect transmission of data from said second set from said second computing device to said first portable computing device, said first set of data including a plurality of items of information about a first subject, said second set of data including a plurality of items of information which correspond with said plurality of items of said first set, wherein said items of said first set are to be respectively compared with said corresponding items of said second set;

(b) first storage means in said first portable computing device for storing said first set of data, said first storage means being capable of storing said first set of data with only a negligable amount of dissipation of power supplied to said first storage means;

(c) first transmitting means connected to said coupling means for transmitting data of said first set from said portable computing device to said second computing device via said coupling means;

(d) first receiving means responsive to said coupling means for receiving data of said second set from said second computing device;

(e) data entry means for effecting manual entry of said first set of data into said first storage means and also effecting manual entry of said second set of data into said first portable computing device;

(f) second storage means in said first portable computing device for receiving said data of said second set from said first receiving means or said data entry means and storing said data of said second set;

(g) first comparing means in said first portable computing device responsive to said first storage means and said second storage means for comparing said data of said first set with said data of said second set to produce a plurality of comparison data items corresponding, respectively, to said items of said first set;

(h) first computing means in said first portable computing device responsive to said first comparing means for operating on said plurality of comparison data items to compute a first number, said first number being indicative of the degree of similarity between said data of said first and second sets; and

(i) first display means in said first portable computing device responsive to said first computing means for displaying said first number.

2. The first portable computing device of claim 1 wherein said first storage means includes a CMOS random access memory.

3. The first portable computing device of claim 2 wherein said first computing means includes a microprocessor.

4. The first portable computing device of claim 3 wherein said second storage means includes an on board random access memory incorporated in said microprocessor.

5. The first portable computing device of claim 3 wherein said first computing means executes a first program to effect said operating on said plurality of comparison data items and wherein said second computing device includes third storage means for storing said transmitted data from said first set and second comparing means responsive to said third storage means for comparing said data of said first set with said data of said second set to produce a plurality of comparison data items corresponding, respectively, to said items of said second set, and second computing means for operating on said comparison data items produced by said second comparing means to compute a number indicative of the degree of similarity between said data of said first and second sets, said second computing means executing a second program, wherein said second program may be substantially identical to or substantially different from said first program, wherein if said first and second programs are substantially identical, said first program recognizes that said first and second programs are substantially identical and effects a first order of transmitting data, receiving data, and operating upon data, and wherein if said first and second programs are substantially different, said first program recognizes that said first and second programs are substantially different and effects a second order of transmitting data, receiving data, and operating on data.

6. A method of utilizing first and second computing devices to compare first and second sets of data, said first computing device being portable, said method comprising the steps of:

(a) entering and storing said first set of data in said first computing device, said first set of data including a plurality of items of information, said second set of data including a plurality of items of information, said plurality of items of said first set corresponding, respectively, to said plurality of items of said second set;

(b) determining whether said second set of data is to be introduced into said first computing device by means of said second computing device containing said second set of data or by means of a keyboard of said first computing device;

(c) if it is determined that said second set of data is to be introduced into said first computing device by means of said second computing device, coupling said first computing device to said second computing device and transferring said second set of data from said second computing device to said first computing device;

(d) if it is determined that said second set of data is to be introduced into said first computing device by means of said keyboard, utilizing said keyboard of said first computing device to effect manual entry of said second set of data into said first computing device;

(e) comparing said items of information of said second set now in said first computing device with corresponding items of information of data of said first set to produce a plurality of comparison data item numbers corresponding to respective ones of said items of information of said first set;

(f) operating on said plurality of comparison data item numbers to compute a first number that is indicative of the degree of similarity between said data of said first set and said data of said second set; and

(g) displaying information represented of said first number to provide an indication of the degree of similarity between said first and second sets of data.
