A synchronous control system includes a logic controller (e.g., microprocessor) which can be put into low power standby or sleep mode by shutting off its clock. A quick-start oscillator (QSO) remains shut off to conserve power when not needed, but awakens rapidly and supplies clock signals to the logic controller for quickly awakening the controller so the latter can to respond to exigent circumstances. One such circumstance can be the drop of a vital supply voltage below a predefined threshold. A low power comparator (LPTC) detects the drop and starts up the QSO which in turn awakens the controller. The controller determines what the reason for the awakening is, quickly responds to the exigent circumstance and then turns the QSO off to thereby conserve power and put itself (QSO) back to sleep. Disclosures are provided for the QSO and a first calibration subsystem used to maintain QSO output frequency within a desired range. Disclosures are provided for the LPTC and a second calibration subsystem used to set its trigger threshold. Disclosure of a novel DAC within the LPTC is also provided.

Systems, methods, and other embodiments associated with resource description framework (RDF) security are described. One example method includes generating, based on sensitivity labels associated with the contents of a triple in an RDF record, a sensitivity label. The example method may also include comparing the sensitivity label to an access label associated with an entity requesting an action associated with the record to be performed. The example method may also include performing the action upon determining that the entity has sufficient permission to request the action.

Extracting and synchronizing an Enterprise Portal application resource types and properties of business objects located in repository is disclosed. The repository is queried without human intervention to determine business object type information and for each business object type its associated properties. A representation of the business object types and associated properties in a format that facilitates synchronization with the enterprise portal application is generated.

A headset can include a cable structure connecting non-cable components such as jacks and headphones. The cable structure can be constructed using a molding process. Different approaches can be used to ensure that a conductor bundle extending through the cable structure remains centered within the cable structure during the molding process. In some cases, a movable tube can be placed in the mold such that the conductor bundle is retained within the tube. As material is injected into the mold and reaches the tube, the tube can be displaced and progressively removed from the mold. Alternatively, the movable tube can be constructed such that the tube may combine with injected material to form a shell of the cable structure. In some cases, gates from which material is provided in the mold can be positioned and controlled to facilitate the injection of material in the mold while maintaining the centered position of the conductor bundle.

Methods and systems of wireless nodes maintaining communication between CEC capable devices are disclosed. One method includes assigning physical addresses to the two wireless nodes based on a physical location of the two wireless nodes relative to a base CEC capable device. Each of the two wireless nodes receives logical addresses from CEC capable devices that are wire attached to each of the two wireless nodes. Each of the two wireless nodes creating a proxy table that includes logical addresses of the CEC capable devices wire attached to the other of the two wireless nodes. Each of the two wireless nodes responds with a proxy acknowledgement when the wireless node receives a packet intended for at least one of the CEC capable devices that is wire connected to the other wireless node, wherein the wireless node has an establish wireless link with the other wireless node.
