Abstract

Bubble domains offer memory, logic, and display capabilities. This device will receive and store information in coded form, allow editing in storage, and convert the compact code to pictorial symbols for display or printing. These functions are performed within the same magnetic sheet and all information is processed while in bubble domain form.

Bubble Domain Composer Display and Printer

Bubble domains offer memory, logic, and display capabilities. This device will receive and store information in coded form, allow editing in storage, and convert the compact code to pictorial symbols for display or printing. These functions are performed within the same magnetic sheet and all information is processed while in bubble domain form.

Referring to Fig. 1, the system has three major parts: a compact code storage; a code converter; and a display. Since pictorial symbols (such as alphabets, numerals, etc.) occupy more space than coded information, they are not economical to store and transmit in their original forms. A large volume of information is translated into compact codes for storage. This is done by the compact code storage unit. When a portion of this information is needed for display, the compact codes are translated into pictorial symbols by the code converter.

Compact Code Storage - A bubble generator G1 subjected to an electrical current in a control line C1 provides an input device. The control line may be actuated manually, or by signals over transmission lines, etc. The storage is shown as a long shift register SR1. Clear control CL1 permits elimination of storage partially (for editing) or fully (for replacement). It is also possible to use many shift registers and decoders for storage rather than a simple long shift register. A splitter SP1 under control of a splitter control SC1, selectively splits domains for recycling in register SR1 and entry into the code converter unit.

Code Converter - Pictorial codes are stored in the code converter in a series of registers SR2, SR3, SR4, and SR5. The codes are stored in the converter by writing in through the use of generators G2, G3, G4, and G5, and the input decoder. The number of shift registers SR2-SR5 in the code converter corresponds to the number of different symbols one wishes to convert. The length of these registers i...
