Using a file server as a central shared database
Various entities need to share data among team members working on the same project without investing in specialized server software. To address this need, an existing standard file server is used to host data for sharing among the team. The file server has not been customized to share the data for the particular application. A user creates a special folder for a project at a user specified location on the file server. Data associated with the project is converted to files and stored in a structure of folders used by the file server to represent the data that is shared. Each client that has subscribed to this shared data synchronizes the data on their local computing device with the data on the file server. Security is provided by using the file server's built-in access controls.
Automatically indexing a collection of files of a selected type
Media clips on a hard drive or other storage are automatically organized in collections and metadata automatically assigned to facilitate subsequent searching for media clips.

A partially “flattened” collection hierarchy is created to simplify browsing the media clips. Sufficient empty files are included to enable a user to readily locate the collections, and metadata comprising keywords derived from the path of each media clip are associated with each of the media clips to facilitate subsequent searching for the files. In addition, the collection hierarchy is automatically updated as changes are made.

When a signal is present on a control node within a SCSC, the SCSC couples a local supply bus of the power domain to a global supply bus. An enable signal path extends through the SCSCs so that an enable signal can be propagated down a chain of SCSCs from control node to control node, thereby turning the SCSCs on one by one. When the domain is to be powered up, a control circuit asserts an enable signal that propagates down a first chain of SCSCs. After a programmable amount of time, the control circuit asserts a second enable signal that propagates down a second chain. By spreading the turning on of SCSCs over time, large currents that would otherwise be associated with coupling the local and global buses together are avoided.

Pre-chamber spark plug
A method and apparatus to maximize spark plug life in pre-chamber spark plugs operating with ultra-lean mixtures and/or elevated engine BMEP is presented. Electrode erosion is reduced by spreading discharge energy over a wider surface area, maintaining fuel concentration in the spark gap, controlling gas static pressure during discharge, and maintaining safe electrode temperature. Energy is spread via a swirling effect created by periphery holes in an end cap, resulting in a lower specific energy discharge at the electrodes. Divergently configured electrodes reduce the spark voltage at high operating pressures and the energy required for ignition. The flow field generated at the electrodes prevents electrical shorts due to water condensation and avoids misfire. The center electrode insulation provides an effective heat transfer path to prevent electrode overheating and preignition. The volume behind the electrodes provides a volume for burnt products from previous combustion cycles and leads to more reliable ignition.
