TL;DR: In this article, an error command is loaded into a command register of the bus error generation circuit via the bus, which decodes the command, and either generates an error condition on the bus during a subsequent bus cycle, or simulates a bus error condition in subsequent bus cycles.
Abstract: In order to test a parallel digital bus, an integrated circuit adapted for coupling to the bus has a bus error generation circuit which generates and/or simulates bus error conditions on the bus. During test, an error command is loaded into a command register of the bus error generation circuit via the bus. The bus error generation circuit then decodes the command, and either: 1) generates an error condition on the bus during a subsequent bus cycle, or 2) simulates an error condition on the bus during a subsequent bus cycle. A status configuration register in the integrated circuit and status configuration registers in other devices on the bus are then read to determine whether the integrated circuit and other devices properly detected and/or handled the generated or simulated error. By providing a bus error generation circuit in the integrated circuits coupled to a bus inside a personal computer, built-in test of the personal computer is facilitated.

TL;DR: In this paper, a speech unit is proposed that enables all devices (11) connected to the bus system (31) to be controlled by a single speech recognition device, e.g., the vocabulary can be dynamically and actively extended by the consumer devices connected to a bus system, and is wellsuited for all kinds of wired or wireless home networks.
Abstract: Home networks low-cost digital interfaces are introduced that integrate entertainment, communication and computing electronics into consumer multimedia. Normally, these are low-cost, easy to use systems, since they allow the user to remove or add any kind of network devices with the bus being active. To improve the user interface a speech unit (2) is proposed that enables all devices (11) connected to the bus system (31) to be controlled by a single speech recognition device. The properties of this device, e.g. the vocabulary can be dynamically and actively extended by the consumer devices (11) connected to the bus system (31). The proposed technology is independent from a specific bus standard, e.g. the IEEE 1394 standard, and is well-suited for all kinds of wired or wireless home networks.

TL;DR: In this paper, a method, apparatus and program for dynamically allocating addresses to computer devices connected to Inter Integrated Circuit (I 2 C) buses are provided, where a bus driver turns on the first bus switch on the bus and then accesses the first device downstream of the switch and allocates a new value to the device's address.
Abstract: A method, apparatus and program for dynamically allocating addresses to computer devices connected to Inter Integrated Circuit (I 2 C) buses are provided. Upon resetting a I 2 C bus, the invention uses a bus driver to turn on the first bus switch on the bus. The invention then accesses the first device downstream of the switch and allocates a new value to the device's address. The invention proceeds to turn on the next switch downstream. A new address is then allocated to the device downstream from the second switch. This process continues until all of the devices connected to the bus have unique addresses.

TL;DR: In this article, a method and system for transferring information between multiple buses is described, where information is transferred through a first bus between multiple first-bus devices and through a second-bus between multiple second-device devices.
Abstract: A method and system are provided for transferring information between multiple buses. Information is transferred through a first bus between multiple first bus devices. Information is transferred through a second bus between multiple second bus devices. Information is transferred through logic means between the first and second buses. Using the logic means, an action of a first bus device is enabled in response to a condition in which a second bus device waits for the action while the first bus device waits for a separate action on the second bus.

TL;DR: In this article, a system for informing users of a bus network about waiting times for buses at stops of the network comprises means (3-6) for generating and transmitting electrical signals representative of the distance (d) between each bus (1) and the "next" stop (2), and means (7) associated with each stop and organized to receive said signals, to select therefrom those signals that concern said stop, and to display at said stop data relating to the waiting time for the "approaching" buses.
Abstract: A system for informing users of a bus network about waiting times for buses at stops of the network comprises means (3-6) for generating and transmitting electrical signals representative of the distance (d) between each bus (1) and the "next" stop (2), and means (7) associated with each stop and organized to receive said signals, to select therefrom those signals that concern said stop, and to display at said stop data relating to the waiting times for the "approaching" buses. The system also includes means for generating electrical signals representative of two past real average bus speeds relating to two different periods immediately before the instant at which the signals are generated, and means for using the average speeds in order to determine the waiting times to be displayed.
