Abstract: Batteries including electrochemical cells, associated components, and arrangements thereof are generally described. In some aspects, batteries with housings that undergo relatively little expansion and contraction even in cases where electrochemical cells in the battery undergo a relatively high degree of expansion and contraction during charging and discharging are provided. Batteries configured to apply relatively high magnitudes and uniform force to electrochemical cells in the battery, while in some cases having high energy densities and a relatively low pack burden, are also provided. In certain aspects, arrangements of electrochemical cells and associated components are generally described. In some aspects, thermally conductive solid articles that can be used for aligning components of the battery are described. In some aspects, thermally insulating and compressible components for battery packs are generally described.

Abstract: A method of forming a glass sheet comprises: (a) forming a ribbon of glass from molten glass with a pair of forming rollers; (b) reducing horizontal temperature variability of the ribbon of glass to be 10° C. or less across 80 percent of an entire width of the ribbon of glass before the ribbon of glass cools to a glass transition temperature; (c) controlling a cooling rate of the ribbon of glass while the ribbon of glass moves vertically downward within a setting zone such that the ribbon of glass has a first average cooling rate before the ribbon of glass cools to the glass transition temperature and a second average cooling rate after the ribbon of glass cools to the glass transition temperature, the first average cooling rate being less than the second average cooling rate; and (d) separating a glass sheet from the ribbon of glass.

Abstract: An upright surface treating appliance includes a main body having a user operable handle, and a stand moveable relative to the main body between a supporting position for supporting the main body in an upright position, and a retracted position. The stand includes at least one surface-engaging rolling member for allowing the appliance to be rolled along a surface using the handle when, with the stand in its supporting position, the main body is reclined rearwardly from its upright position. The appliance further includes a stand retaining mechanism for releasably retaining the stand in the supporting position and from which the stand is releasable upon application of a force to the main body. The stand retaining mechanism includes a system for increasing the force required to release the stand when the main body is reclined rearwardly from its upright position.

Abstract: In a method of detecting signal degradation conditions in synchronous digital signals, the error monitors first detect the presence and/or absence of a particular bit error ratio by integrating received parity errors over time. Subsequently a monitor client reacts to notifications from bit error rate monitors that the state of the presence/absence of specific bit error ratios has changed to generate an alarm condition when appropriate.
