    Abstract: A battery pack is provided which includes an enclosure. The enclosure includes a battery cell compartment and a vent. The battery cell compartment is a sealed compartment, except for the vent, and the vent facilitates pressure-induced venting of gas from the battery cell compartment. One or more battery cells are disposed within the battery cell compartment, and the battery pack also includes a filter system associated with the enclosure. The filter system filters the pressure-induced venting of gas from the battery cell compartment resulting from a thermal runaway event at a battery cell of the one or more battery cells within the battery cell compartment of the enclosure.

    Abstract: Tamper-respondent assemblies, electronic assembly packages, and methods of fabrication are provided which include multiple, discrete tamper-respondent sensors that overlap, at least in part, and facilitate defining a secure volume about one or more electronic components to be protected, such as an electronic assembly. The tamper-respondent sensors include a first tamper-respondent sensor and a second tamper-respondent sensor, which may be similarly constructed or differently constructed. In certain embodiments, the tamper-respondent sensors wrap, at least in part, over an electronic enclosure, and in other embodiments, the tamper-respondent sensors cover, at least in part, an inner surface of an electronic enclosure to facilitate defining a secure volume in association with a multilayer circuit board to which the electronic enclosure is mounted.

    Abstract: Methods of fabricating tamper-respondent assemblies provided which include a tamper-respondent electronic circuit structure. The tamper-respondent electronic circuit structure includes a tamper-respondent sensor. The tamper-respondent sensor includes, for instance, at least one flexible layer having opposite first and second sides, and circuit lines forming, at least in part, at least one tamper-detect network, such as one or more resistive networks. The circuit lines are disposed on at least one of the first side or the second side of the at least one flexible layer. At least one region of the tamper-respondent sensor is fabricated with increased susceptibility to damage from mechanical stress associated with a tamper event. The at least one region of increased susceptibility to damage facilitates detection of the tamper event by the tamper-respondent sensor.

    Abstract: Tamper-respondent assemblies and methods of fabrication are provided which include at least one tamper-respondent sensor having unexposed circuit lines forming, at least in part, one or more tamper-detect network(s), and the tamper-respondent sensor having at least one external bond region. The tamper-respondent assembly further includes at least one conductive trace and an adhesive. The conductive trace(s) forms, at least in part, the one or more tamper-detect network(s), and is exposed, at least in part, on the tamper-respondent sensor(s) within the external bond region(s). The adhesive contacts the conductive trace(s) within the external bond region(s) of the tamper-respondent sensor(s), and the adhesive, in part, facilitates securing the at least one tamper-respondent sensor within the tamper-respondent assembly. In enhanced embodiments, the conductive trace(s) is a chemically compromisable conductor susceptible to damage during a chemical attack on the adhesive within the external bond region(s).

    Abstract: Methods of fabricating tamper-respondent electronic circuit structures and electronic assembly packages are provided which include, at least in part, a tamper-respondent sensor including one or more formed flexible layers of, for instance, a dielectric material, having opposite first and second sides, and circuit lines defining at least one resistive network. The circuit lines are disposed on at least one of the first side or the second side of the formed flexible layer(s). The formed flexible layer(s) with the circuit lines includes curvatures, and the circuit lines overlie, at least in part, the curvatures of the formed flexible layer(s). In certain embodiments, the formed flexible layer(s) may be one or more corrugated layers or one or more flattened, folded layers.

    Abstract: Tamper-respondent assemblies and methods of fabrication are provided which include an electronic enclosure and a tamper-respondent electronic circuit structure. The electronic enclosure encloses, at least in part, at least one electronic component to be protected, and includes an inner main surface, and an inner sidewall surface which has at least one inner-sidewall corner. The tamper-respondent electronic circuit structure includes a tamper-respondent sensor covering, at least in part, the inner sidewall surface of the electronic enclosure. The tamper-respondent sensor includes multiple slots provided therein. The multiple slots facilitate disposing the tamper-respondent sensor to cover the at least one inner-sidewall corner of the inner sidewall surface by allowing for one or more regions of overlap of the tamper-respondent sensor at the at least one inner-sidewall corner of the electronic enclosure.
