20100303055 | Method for Assigning Data Messages to Time Slots in a Wireless Data Bus System Having Hidden Subscribers - A method for assigning data messages to time slots in a wireless data bus system having hidden subscribers (“hidden nodes”), wherein each subscriber is initially assigned at least one time slot for exclusive use per transmission cycle and the time slot can be engaged by another subscriber for use in the event of non-use by the subscriber. Moreover, an engagement matrix is provided which records, for each subscriber, those time slots of other subscribers for which engagement is permitted in a data message cycle. In accordance with the invention, the engagement matrix is configured to block at least the engagement of the time slot of another subscriber for a subscriber if it is another subscriber (“hidden node”) that cannot be reached by radio by the subscriber. | 12-02-2010 |
20110136524 | Energy and Time-Efficient Set-Up of a Wireless Communication System - The invention relates to a method for the wireless communication between a base station and several devices. The base station monitors the non-use of the transmission of a device telegram to the base station in a time range, or in several consecutive time ranges, between two synchronization signals (S) in the communication mode and after a duration (Tping) of non-use emits an identification telegram (GWping). | 06-09-2011 |
20120170567 | Transmission Method - A transmission method in a wireless data bus network, wherein the method comprises data transmission cycles made of a plurality of time slots of matching length. Each time slot is thereby associated with a particular client on the data bus network exclusively for transmitting data. In accordance with the invention, an allocation duration is started for each time slot, wherein the time slot is utilizable exclusively by the associated client for transmitting data until the duration expires. Alternatively, the time slot that has become available after the allocation duration has expired can be exclusively associated with a different client on the data bus network in accordance with an allocation method for transmitting data. | 07-05-2012 |
20120218766 | LIGHT SIGNAL TRANSMITTER AND LIGHT RECEIVER FOR AN OPTICAL SENSOR - A light signal transmitter and a light receiver for an optical sensor may be used for an industrial automation system. The light signal transmitter has a semiconductor-based light source for generating light. The semiconductor-based light source is disposed in an installation space between outer layers of a multi-layer circuit board. The light emission direction of the semiconductor-based light source is oriented substantially parallel to the layers of the printed circuit board. A deflection unit deflects the light emitted by the semiconductor-based light source in a direction substantially perpendicular to the layers of the printed circuit board. In the case of the light receiver, a light sensor is provided in place of the light source. Such optical sensors can be designed in a particularly flat and installation-friendly manner. | 08-30-2012 |
20120224537 | Method for Transmitting a Beacon in a Star Network (Master-Slave Ad Hoc Network) and a Sensor Node in a Star Network - A method for transmitting a beacon for a star network in manufacturing automation, for use in a communications protocol, such as IEEE Standard 802.15.4e, for manufacturing automation, using at least one gateway and at least one sensor node, wherein the beacon comprises a field including information about a number of base time slots in a superframe. | 09-06-2012 |
