Firewall techniques for colored objects on endpoints
Threat detection instrumentation is simplified by providing and updating labels for computing objects in a context-sensitive manner. This may include simple labeling schemes to distinguish between objects, e.g., trusted/untrusted processes or corporate/private data. This may also include more granular labeling schemes such as a three-tiered scheme that identifies a category (e.g., financial, e-mail, game), static threat detection attributes (e.g., signatures, hashes, API calls), and explicit identification (e.g., what a file or process calls itself). By tracking such data for various computing objects and correlating these labels to malware occurrences, rules can be written for distribution to endpoints to facilitate threat detection based on, e.g., interactions of labeled objects, changes to object labels, and so forth. In this manner, threat detection based on complex interactions of computing objects can be characterized in a platform independent manner and pre-processed on endpoints without requiring significant communications overhead with a remote threat management facility. |

Decentralized edge computing transactions with fine-grained time coordination
Various approaches for coordinating edge computing transactions are described, based on the generation and verification of fine-grained timestamp values among distributed computing entities in an edge computing system. In an edge computing system, an edge computing device performs operations to obtain transaction data, a timestamp, and a timestamp signature for a transaction, with the timestamp generated from a secure (and attestable) timestamp procedure that is coordinated with another entity (including via a network-coordinated timestamp synchronization). This timestamp is verified by the device based on the timestamp signature and the transaction data for the transaction, and the transaction is conducted (e.g., using a value of the timestamp) at the device or elsewhere in the system based on successful verification. In further examples, the coordinated timestamp enables multi-version concurrency control (MVCC) database transactions, verification of blockchain transactions, or other uses and verifications of timestamp values. |

Bilevel equalizer for battery cell charge management
An equalizer circuit provides both passive and active cell voltage equalization in a battery pack to improve charge and discharge capacity at a low cost. The equalizer circuit is a bilevel circuit that uses both passive equalizers and active equalizers to balance cell voltage.

Power conversion system and method
A power conversion system has a plurality of power tracking converters connected in parallel to an output of an energy source such as a solar system. A communication system between the converters implements a sequence of operation of the converters, such that in response to a communication signal from a preceding converter in the sequence, each converter performs tuning of its power tracking function and then provides a communication signal to the next converter in the sequence. Each converter for example functions as a maximum power point tracking system. The system may be made from a set of smaller units so that different systems may be formed from a small set of standard components. By operating the converters in a sequence, conflict between the converters and instability is avoided. |
