  • 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: 9125140
    Abstract: Background scan for 802.11 client devices allows them to keep most of its components in low power mode when certain criteria are not met. A method for changing dynamically those criteria according to the air data traffic conditions is described in the present invention. This increases the time the system remains in sleep mode and consequently improves the standby current consumption to portable 802.11 enabled media.

  • 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.
