摘要： A magnetic memory system is provided that includes magnetic domain data chips having a block replicate organization wherein the system may include data chips having one or more defective minor loops. A dedicated minor loop is provided on the chip to store a redundancy map for locating the defective minor loops. The dedicated minor loop also provides for storing a synchronization pattern for initializing the system by having each minor loop properly addressed for transferring magnetic domains. The dedicated loop can only be accessed by a separate swap pin preventing a write operation by the user thus preserving the data stored therein.

摘要： Method and apparatus for testing and setting the field strength of permanent magnets in a magnetic bubble domain chip module, wherein the final molded module is formed to contain a pair of longitudinal slots which run through the module on opposite sides thereof. The module is inserted, via said slots, onto conducting members of a magnetic bubble module testing apparatus. The conducting members effectively provide one turn coils on each side of the module. Current is induced in these coils in such a way as to either add to or subtract from the bias field provided for the magnetic bubble domain chip by the permanent magnets of the module. The module is tested to determine the upper and lower operating levels of the bias field for effective operation of the chip, and the device is remagnetized to set the bias field of the module in the center, or optimal point, of the bias margin.

摘要： A magnetic domain memory system is provided that includes magnetic domain data chips having a major-minor loop organization wherein the system may include data chips having one or more defective minor loops. An erasable non-volatile semiconductor memory device is provided to record locations of defective minor loops for each chip in the system. In order to update the defective minor loop locations when a data chip is replaced a random access memory is provided to store the present map of locations and substitute data designating the new defective minor loops. A method of replacing the map in the erasable non-volatile semiconductor memory is also disclosed. An array of binary one bit data in the form of "1" or "0" is stored in the non-volatile semiconductor memory to designate defective and operative minor loops.

摘要： A magnetic bubble memory chip structure on which a plurality of magnetic bubble storage loops are provided for containing information data as represented by bubbles and voids and including a dedicated area on the chip for containing redundancy data as represented by a chain of bubbles and voids arranged in a predetermined manner to identify good and defective information data storage loops. The redundancy data-containing dedicated area of the chip comprises a plurality of redundancy data-containing storage loops of equal number to the information data-containing storage loops so as to correspond thereto in a one-on-one relationship, with the number of individual bit positions included in each information data-containing storage loop being significantly greater than the number of bit positions included in each individual redundancy data-containing storage loop. At least one bubble detector is included on the chip, being associated with the information data-containing bubble storage loops and the redundancy data-containing storage loops for receiving readout of information data and redundancy data in an alternating coordinated sequence with each bit of information data from a respective information data-containing storage loop being preceded by a bit of redundancy data from the corresponding redundancy data-containing storage loop which identifies whether the following bit of information data is from a good or a defective information data-containing storage loop. The output from the detector is operably controlled by appropriate logic circuitry for restricting the usable readout from the information data-containing bubble storage loops to data which is delivered from good storage loops as determined by the redundancy data imparted by respective redundancy data-containing storage loops.

摘要： A high-speed RF link connects multiple users with individual data appliances to a projection system in a multi-user meeting. The RF link enables high-speed transmission of graphics data in either compressed or uncompressed form to the projection system where application-aware software/hardware carries out any necessary de-compression before display of the graphics data. The RF link also enables high-speed links between multiple users and between one or more users and an external network via a wireline connection to the projection system. A user's capability may also be enhanced by the addition of a local keyboard and a local display.

摘要： An educational learning aid which obtains its procedural data via bar code or other indicia imprinted on the edge of detachable work book sheets. The aid holds the detachable sheet over a touch sensitive array of switches so that touching or marking of the sheet is sensed by the underlying switches in the aid. The correct content of the answers is communicated to the aid by a bar code or machine readable section either on a work sheet or on a second sheet. In this fashion the operator responds to printed material on the sheet and is verbally reinforced by the learning aid for correct answers. Preferably a running tally of the operator's correct responses is kept and he is informed at the end of the exercise of his score. This score is optionally printed upon the paper upon completion of the exercise.
