Abstract: An electronic system may include an electronic device including a portable housing, communications circuitry, a volatile memory and configured to store at least one encryption key, and a non-rechargeable battery coupled to the volatile memory. The non-rechargeable battery may have an internal resistance, and the electronic device may further include an internal resistance measurement circuit configured to measure the internal resistance of the non-rechargeable battery, a processor configured to collect and store battery performance data including the measured internal resistance and a corresponding operating parameter, and a rechargeable battery removably coupled to the portable housing and configured to supply power to the volatile memory, with the non-rechargeable battery supplying power to the volatile memory otherwise.

Abstract: A system and method of detecting, quantifying, and characterizing corrosion and degradation of an article, includes receiving signals indicative of a stack of images of a surface of the article; determining depth and nature of features in the stack of images; generating a surface model of the article in response to the determination of the depth and the nature of features; determining features of interest from the surface model; comparing the features of interest with predetermined information on the article; and characterizing the article as corroded or degraded in response to the comparisons of the features of interest.

Abstract: A system and method of condition based maintenance of a fiber network includes a processor and memory having instructions that when executed cause the system to transmit an optical signal over a plurality of fiber links in the fiber network; receive a response signal in response to the transmitting of the optical signal; and determine one or more condition indicators in response to the receiving of the response signal.

Abstract: An electrical assembly which secures a detached cable/connector assembly to a substrate of a printed circuit board. The assembly has a printed circuit board that is mounted to a first surface of the substrate. The printed circuit board is coupled to an electrical connector assembly by a flexible cable. The electrical connector assembly can be plugged into an auxiliary device such as a CD-ROM. The electrical connector assembly has a tab that is inserted into an aperture located in the second surface of the substrate, to secure the connector assembly when the connector is not attached to the auxiliary device.
