  • Patent number: 8291241
    Abstract: Systems and methods are disclosed for detecting the connection of a FireWire peer to a FireWire device. In one embodiment, a device may determine whether a peer connection is present based on peer detection circuit configured in each FireWire port of a FireWire device. When no peer is connected to a device, a peer connection in the circuit may be open, and a current path through the circuit may provide a low detect signal, indicating that no peer is connected. When a peer is connected to a detecting device, the current may pass through a resistance in the detected peer to provide a high detect signal, indicating that a peer is connected. In some embodiments, once a peer is detected, the FireWire system of the detecting device may be powered on, and the peer detection circuit may be powered off.

  • Patent number: 5935259
    Abstract: A system and method for preventing damage to media files within a digital camera comprises a power manager for detecting power failures, an interrupt handler for responsively incrementing a counter device and a removable memory driver for performing memory access operations, evaluating the counter device to determine whether a power failure has occurred during the memory access operation and for repeating the memory access operation whenever a power failure has occurred during the memory access operation.
