Patent
Method and apparatus for constructing wired-and bus systems
TL;DR: In this paper, a large multimaster I 2 C bus system is partitioned into smaller bus segments and the bus segments are connected by bridges that isolate the segments and direct selected transactions and commands between the segments.
Patent
Method and apparatus for powering up an electronic system after AC power has been removed
TL;DR: In this article, the amount of required power is determined before power up based on the actual power load present, which is determined by sensing load indicators in each load device and computing the total power load.
Patent
Realtime multithreaded hot-plug control
TL;DR: A hot-plug control system for a computer system includes a hotplug device; a set of hotplug threads that regulate operations in the hotplug devices; and a finite state machine that controls execution of instructions using the set of threads as discussed by the authors.
Patent
Method and apparatus for interconnecting wired-and buses
TL;DR: In this article, a bus topology can be designed to maximize the ability to isolate faults within a given segment, thereby improving the ability of technicians to diagnose problems in very large I2C implementations.
Patent
Method and apparatus for configuring multiple segment wired-AND bus systems
TL;DR: In this article, the bus topology is a tree configuration and the configuration host performs a recursive procedure that configures each branch of the tree, and during this configuration process the internal bridge registers and address bitmap in each bridge are populated.
