  • Patent number: 5893900
    Abstract: An apparatus for processing and editing an analog audio recording. An analog audio recording device comprises a data receiver for receiving analog audio data and a plurality of analog markers, an analog output for outputting the analog audio data with the plurality of analog markers, and a processing unit coupled to the analog output. The processing unit comprises digitizing circuitry for digitizing the analog audio data with the plurality of analog markers to create a digital audio file comprising digital audio data and a plurality of digital markers. The processing unit also comprises integrated circuit memory storing editing software for editing the digital audio file using the plurality of digital markers to create an edited digital audio file.

  • Patent number: 5860124
    Abstract: A nonvolatile memory having a plurality of individually erasable blocks is used to store sectors of a file. A method of overwriting the file includes the step of receiving a frame of data. The logical sector that the frame is to be written to is determined. The logical sector corresponds to a first sector located at a first offset in a first block of the nonvolatile memory. The first block also has an associated first logical block number. The frame of data is written to a second sector. The second sector is located at a second offset in a spare block. The first and second offsets are identical. The logical block number of the spare block is updated to be the same as the first logical block number.

  • Patent number: 5848298
    Abstract: A companion computer system for a host computer wherein the host computer includes an interface for electrically and mechanically interfacing to the companion computer. An example is a PCMCIA slot. The companion system includes a PC card with an interface which mates with the interface on the host. A bus is located on the PC card. A CPU is located on the PC card and connected to the bus. A display is located on the PC card and connected to the bus. An input device is located on the PC card and connected to the bus. A non-volatile memory module is located on the PC card and connected to the bus. A low power random access memory module is located on the PC card and connected to the bus. A power supply is located on the PC card and connected to the components of the PC card An operating system is located in the non-volatile memory.

  • Patent number: 5809558
    Abstract: A memory management method is provided for a nonvolatile memory having a plurality of blocks each of which can be electrically erased and programmed. A data file to be stored in the nonvolatile memory is received. A number of blocks that are available for data storage are located from the plurality of blocks. The data file is stored in a first block of the number of blocks if the size of the data file is smaller than the total storage space of the first block. The data file is stored in the first block and a second block of the number of blocks if the size of the data file is larger than the total storage space of the first block but smaller than the total storage space of the first and second blocks. Unoccupied space of the first or second block by the data file is not used to store other data files such that no file reallocation operation is needed when the first or second block is to be erased.

  • Patent number: 5687279
    Abstract: A method for retro-storing analog information in a memory circuit first processes first analog data into first digitized data. The first digitized data are then stored in the memory circuit. Second analog data are then received and processed into second digitized data. If storage of the analog information is now required, the second digitized data are stored with the first digitized data in the memory circuit. If storage is not required, the first digitized data are deleted from the memory circuit and the second digitized data are stored in the memory circuit. An integrated storage circuit for retro-storing and retrieving analog information is also described. The circuit includes a control circuit for controlling a processing circuit to store digitized analog data in a nonvolatile memory in response to a control signal. When the control signal is not asserted, the control circuit controls the digitized analog data to be stored in the buffer circuit in a closed loop manner.

  • Patent number: 5631741
    Abstract: An electronic copying apparatus provides a touch sensitive area placed under a paper on which an image is produced. Pressure on the touch sensitive area produced in rendering the image on the paper generates signals which are detected by a processor and stored as a series of pixel positions in a non-volatile solid-state memory array such as a flash EEPROM memory array. The image stored in the memory array may be read from the array by a computer and utilized as are other files in a computer.

  • Patent number: 5619396
    Abstract: A modular PCMCIA card comprises a base member conforming to the Type I or Type II physical dimensions and an add on section which mechanically and electrically connects with the base member and has dimensions such that when the base member and the add on section are joined, they conform to the dimensions of a PCMCIA Type III card. The add on section may contain one or more functional units of a stand alone computer system and may also contain a battery, a modem, pager and/or an infrared transceiver for communicating with printers, computers or controlling other devices.

  • Patent number: 5432510
    Abstract: An ambidextrous, single hand data management device that has been ergonomically optimized to facilitate multiple key per character input, chording. The device has an arrangement of multiple keys which are so situated that the device can be held in either the left or the right hand, by a large range of hand sizes, and data can be quickly and conveniently input, that is, any combination of keys can be quickly and conveniently actuated with a "Microwriting" chordic type of data input, without a hand strap and without dropping the device. The ergonomic arrangement of keys on the casing allows for the device to remain stationary relative to the palm of the hand while that hand is in a multiplicity of orientations. The device can serve as a primary data input device or as a data storage and retrieval device for things like inventory control, names and addresses or daily schedule reminders or, as a combination of all of these.
