  • Patent number: 11953539
    Abstract: An arrangement for monitoring the operation of a machine intended to be tracked by a real-time locating system comprises: a tag intended to be arranged on the machine, the tag being configured to generate a wireless tag signal allowing determination of a position of the tag; and at least one detector intended to be arranged on the machine, the at least one detector being configured to detect at least one characteristic of a magnetic field generated by the machine. Detection of the at least one characteristic is indicative of the machine being operative. The arrangement makes it possible to obtain a detailed understanding of how the machine is used in a cost-effective manner. A real-time locating system comprising such an arrangement and a method for monitoring the operation of a machine are also disclosed.

  • Patent number: 7672328
    Abstract: This invention can generally be described as an overall transmit (TX) scheduler state-machine that is broken down into two different state-machines: One first TX-scheduler state-machine (FTSM), executed in software, and one second TX-scheduler state-machine (STSM) executed in hardware, which is operating in four different basic states. The functional partitioning between the two state-machines is such that the most constrained real-time requirements are allocated to the STSM, while all complex decisions and non time-critical controls are allocated to the FTSM. The invention also relates to a terminal comprising the invented transmit scheduler.

  • Patent number: 7324226
    Abstract: A method and an arrangement in a data communications system. The object of the invention is to achieve a wireless communication between a processing unit and a printer using a safe transmission and an increased transmission range compared to the infrared transmission. The solution is a way of printing a document in a data communications system using a protocol profiled for printing in the Bluetooth protocol architecture.
