Definitions

  • the present invention relates in general to removable storage devices. More particularly, the present invention relates to a portable data storage device for connecting to digital appliances and automatically downloading digital data from the digital appliances.
  • the application of digital technology is rapidly being applied to a host of consumer appliances.
  • the digital camera is a significant application that is widely expected to become a major application of digital technology.
  • the digital camera employs a microprocessor and other supporting circuitry to convert an analog image into a set of digital pixels, thereby forming a digital image.
  • the digital pixels are stored in a memory area of the camera for later retrieval and processing.
  • the digital images can then be downloaded to a personal computer (PC) or a notebook computer for viewing and editing.
  • PC personal computer
  • notebook computer for viewing and editing.
  • Fig. 1 is a block diagram showing an overall structure of a conventional digital camera.
  • the camera 10 has a central processing unit (CPU) 12 which functions as a control unit, an image photographing unit 14, a data converting and compressing unit 16, a memory controller 18 which functions as an interface, a data memory 20 which is a storage medium, a first in first out (FIFO) circuit 22, and a communication port 24.
  • CPU central processing unit
  • FIFO first in first out
  • the CPU 12 controls operations of the components of the camera 10.
  • the data converting and compressing unit 16 converts the analog signals into digital signals which represent the image data, and compresses and encodes the image data.
  • the image data is written into the data memory 20 through the FIFO circuit 22 by operation of the memory controller 18.
  • the data memory 20 is typically a standard flash memory PC card or other nonvolatile memory and is typically constructed in accordance with the PCMCIA (Personal Computer Memory Card International Association) standard.
  • the image data can be read out from the data memory 20 through the FIFO circuit 22 by operation of the memory controller 18.
  • a communication port 24 is provided to download image data directly to a PC.
  • Flash memory is the most common form of digital image storage space in a digital camera. When the memory area becomes full, the memory area must be cleared before more pictures can be taken. In the earliest digital cameras to arrive in the marketplace, the flash memory modules were not removable. Those cameras require that the camera be connected to a PC or notebook computer to download the images. Newer cameras provide a removable flash memory module. Accordingly, when such a memory module is full, it can be replaced with an empty memory module. The user is then free to take additional pictures and postpone the download to a later time. Unfortunately, although the flash memory modules are removable, they are also relatively expensive. As a result, a user is likely to purchase only one or two additional memory modules, which still limits the user's picture taking capability.

  • the docking station 400 can also convert the data to SCSI, parallel, or any other format, using conventional conversion techniques, prior to sending the data to the PC 500.
  • the PC 500 acts as the host and controls file directory and data transfers through the buffer manager 410.
  • the data download device 200 and the data storage device 255 use the docking station buffer manager
  • Commands such as SCSI or parallel port commands, are passed to the data storage device 200 and to the data storage device 255 through the docking station buffer manager 410 over the interface buses 220 and 260.
  • the docking station 400 supplies power to the data download device 200.
  • the data download device 200 When the data download device 200 is docked, it receives power from the docking station 400 through the power supply 420.
  • the docking station 400 receives power from the PC 500 and supplies power to the data download device 200 through the docking station connector 405.
  • the docking station 400 preferably charges a rechargeable battery if that is used as a power source 246 for the data download device 200. If a standard battery pack (e.g., 9 volt or AA alkaline) is installed as a power source 246, the docking station 400 does not attempt to charge the batteries.
  • a standard battery pack e.g., 9 volt or AA alkaline
  • the controllers 210, 258 of the data download device 200 and the data storage device 255 do not drive the interface bus.
  • the controllers 210, 258 are idle while in the docking station 400.
  • the firmware of the data download device 200 and the data storage device 255 bypass the interface bus and enable a buffer manager bypass interface (not shown) (e.g. , the devices 200, 255 set register bits disabling the interface bus and enabling a buffer manager bypass interface) .
  • the data download device 200 and the data storage device 255 operate in a bypass mode using commands to/from the docking station 400.
  • the docking station 400 has control over the interface.
  • the data generating device communication or data transfer protocol and driver software are initially stored in a memory, storage area, device or media, such as a ROM, a RAM, a hard drive or a floppy disk.
  • the memory, storage area or device can reside on the data generating device or at a remote site, such as on a PC or on a computer network, such as at an internet website.
  • Fig. 10 is a flowchart showing an exemplary process of providing data generating device protocol and driver software to a data download device in accordance with the present invention, such as the devices described with respect to Figs. 2 and 4.
  • the data download device is connected to a device, such as a personal computer, that accesses the storage area, device or media on which the desired firmware resides.
  • the device driver of the data download device is loaded into the PC at step 605, and this accesses a software menu which lists various data generating devices.
  • the desired data generating device is selected.
  • the firmware of the data generating device is downloaded from the storage area, device or media via the PC, or accessed from a remote computer network such as an internet website, and stored into a memory, such as the memory 42 of Fig. 2 or the first memory 245 of Fig. 4, of the data download device.
  • the data download device can upload and store additional camera transfer protocols and drivers as they are introduced into the marketplace.
  • Another exemplary process of providing data generating device protocol and driver software to a data download device in accordance with the present invention includes uploading the device protocol and driver software directly from the data generating device if it is contained within the data generating device.
  • the data generating device is connected to a data download device.
  • the data download device (e.g., device 200 in Fig. 4) determines the type of data generating device it is connected to and then determines if it already has that particular device's protocol and driver stored in its memory (e.g., first memory 245 in Fig. 4) . If the data download device does not contain the data generating device's protocol and driver, the data download device transfers the protocol and driver data from the memory of the data generating device and stores it in its memory (memory 245) .
  • the portable device of the illustrated embodiments is preferably a digital camera
  • the present invention is not limited thereto.
  • the present invention can be applied to a smart phone, personal digital assistants, and notebook computers (not shown) .
  • Any digital data, such as sound data, can be downloaded and saved by the present invention, not just digital image data.
