  • Patent number: 8852784
    Abstract: Methods and apparatus supporting an electrical connection are disclosed. Systems previously equipped with wire interfaces, such as battery terminals, can be equipped with a connector assembly to significantly reduce a hazard of electrical shock to a user. The connector assembly includes a stress relief component that attenuates a force, applied to the stress relief component, to reduce its effect on the connector assembly. By attenuating the force, the connector assembly maintains a substantially fixed position relative to the battery pack component and mitigates a potential for disruption in electrical connectivity. Techniques disclosed herein benefit users of battery packs or other devices as well as manufacturers by increasing safety, reliability, and ergonomics.

  • Patent number: 8510614
    Abstract: A bad block identification method for a memory is provided. The memory includes at least one memory block for storing data. A data decoding function is performed on the data, and it is determined whether the data decoding function was performed successfully. If the data decoding function was not performed successfully, at least one predetermined location in the memory block is checked. It is determined whether the predetermined location is marked by predetermined information. If the predetermined location is not marked by the predetermined information, the memory block is identified as a bad block.

  • Patent number: 8226425
    Abstract: Methods and apparatuses supporting an electrical connection in a manner that eliminates or reduces a danger of electrical sparking are disclosed. A sparkless electrical connector has a conductor, configured to provide flow of electricity between an electrical source and a load, and a resistive element, operatively coupled to the conductor, to resist flow of electricity during a state of partial connection with the electrical source or the load. The resistive element may be not in contact with a terminal of the source or load during a state of full connection. The resistive element may be a coating of an anodized material on a pin of the conductor. The coating provides a resistance sufficient to prevent sparking during connection of the conductor and at least one of the electrical source and the load. Techniques disclosed herein benefit users and manufacturers in the areas of safety, cost, simplicity, and reliability.
