TLDR
In this paper, the authors propose a method and arrangement for the transmission of data, in digital form, in a bus system, which includes a central unit, several stations, as well as a bus line or data bus.Abstract:
A method and arrangement for the transmission of data, in digital form, in a bus system, which includes a central unit, several stations, as well as a bus line or data bus. During operation, the following different transmission phases take place: An initiation phase, in which the central control unit queries all of the stations and prepares a request phase; the request phase, in which the individual stations report a required bus access; an allocation phase, in which each station obtains a time slot in response to its request; and a data phase, for transmission of the data. The central unit includes a phase control, a request collector, a time slot allocator, and a register. A number of the stations are provided with a request generator in such a way that the latter can signal a need to the bus access. Thus, an optimum utilization of the transmission capacity is achieved, possibly by switching stations off. However, a rapid bus access is possible at any time for important stations.read more

Multiplex transmission system for use in vehicles
TL;DR: In this paper, a multiple transmission system for use in a vehicle, in which a second node having a control function sends a command to first nodes of an ordinary type when an transmission error rate higher than a certain level takes place or at certain time intervals to effect system refreshment which resides in the following operation.

Method and apparatus for reducing the likelihood of contention and resource misallocation in a packet transmission system
TL;DR: In this paper, the authors proposed to reduce request traffic contention and the likelihood of resource misallocation by limiting the number of duplicate requests transmitted by a remote unit (112), which operates to reduce the contention of request traffic.

TL;DR: In this paper, a distributed intelligence network (10) using time and frequency domain multiplexing is described, where each node determines its skew and requests downloading of program code and configuration data.
Patent
Resource management scheme and arrangement
TL;DR: In this article, the authors propose a centralized and distributed management of capacity in a DTM type (digital synchronous transmission), in which the network use the capacity which are divided into cycles, which are in turn divided into control time slots for signaling and data time slots to data transmission, and where each data time slot is associated with a token.
Patent
Deterministic network protocol
TL;DR: In this paper, a deterministic network protocol for connecting critical sensors, actuators and computing elements on a bi-directional, time-multiplexed, fiber optic or other media data bus, such that critical messages have concisely bounded latency and non-critical messages may be sent without impacting critical messages.
