Abstract: A printed circuit board (PCB) includes a first plurality of conductive paths having first ends at an inner radius of the PCB and second ends at an outer radius of the PCB. The PCB further includes a second plurality of conductive paths having first ends at an outer radius of the PCB and second ends at an inner radius of the PCB. The PCB further includes a first plurality of conductive vias that pass through the PCB at the outer radius of the PCB and couple second ends of the first plurality of conductive paths to first ends of the second plurality of conductive paths. The PCB further includes a second plurality of conductive vias that pass through the PCB at the inner radius of the PCB and electrically couple second ends of the second plurality of conductive paths to first ends of the first plurality of conductive paths.

Abstract: A battery balancing system including two battery modules connected in series, wherein each module is coupled to a balancing circuit. The balancing circuit is selectively operable between two modes: a dissipative mode, wherein the balancing circuit is connected in parallel to the respective battery module and dissipates energy from the battery module as light; and a latent mode, wherein the balancing circuit is disconnected from the battery module. A method of balancing a battery, including: charging a module of the battery, the module including at least one electrochemical cell; monitoring a system parameter indicative of the module charge; determining that a dissipation condition has been met based on the system parameter; and connecting a balancing circuit to the module upon determination of the dissipation condition being met, wherein the balancing circuit dissipates energy from the battery module as light.

Abstract: A method is described of compositing graphic elements in a pixel-based renderer (18). A first graphic element is received (step 2601) having a first colour and a first opacity and a second graphic element is received (step 2602) having a second colour and a second opacity. A blend output is obtained from a blend function dependent on the first colour and the second colour; and a resultant colour is determined (step 2603) of a compositing operation on the first and second graphic elements, the resultant colour being dependent on the blend output and otherwise being independent of the second colour.

Abstract: A mixed text and image layout algorithm capable of supporting Unicode text and arbitrary content definitions for geometric layout with worst case two-pass layout placement procedure. Layout of Unicode text requires a number of distinct processing steps commencing with classification of input characters into contiguous groups of identical directionality, writing system and possibly script (and language) followed by mapping of character groups to glyphs for display purposes followed by a layout taking into account font display characteristics, embedded directionality level and shape of container for layout contents. Layout is best-case achieved in a single layout pass and worst-case in two passes. During layout information is cached to facilitate incremental changes to an existing layout in order to minimize refresh operations for editing display purposes. An optional two-pass operation on the layout result may be used to generate ordered rendering operation to support so-called Z-index display.

Abstract: A method (1000) of compositing a group of graphical objects (B). The method (1000) forms the group of objects (B) in a temporary buffer (W). For each object (C, D) in the group of objects (B), a corresponding clipping path is provided. A resultant clipping path (Z) defined by a union of the clipping paths is calculated. The group of objects from the temporary buffer (W) is composited to a main buffer (V) through the resultant clipping path (Z).
