  • Patent number: 12089122
    Abstract: In an embodiment an ultra-wideband indoor real-time location system for determining positions of mobile tag devices within a localizing area includes a plurality of UWB signal transmitters located at preset positions and defining the localizing area, wherein the UWB signal transmitters are configured to operate with synchronized clocks and transmit UWB signals based on a UWB frame format, and wherein the UWB frame format includes unique information content for the UWB signal transmitter and at least one mobile tag device comprising a signal reception unit configured to receive the UWB signals, a time detection unit configured to derive respective arrival time points for the received UWB signals, an identification unit configured to derive the unique information content from the received UWB signals and a control unit configured to process the unique information content and the arrival time points for at least a subset of the UWB signal transmitters in a localizing algorithm to derive a position of the mobile

  • Patent number: 11573595
    Abstract: An embodiment method is disclosed for deriving an estimation value of a clock-error for a slave clock, wherein the slave clock is set at a nominal slave period and outputs a sequence of slave clock signals at an actual slave period, and wherein a difference between the actual slave period and the nominal slave period is approximated by the estimation value of the clock-error.

  • Patent number: 6723779
    Abstract: A latex which forms a film by evaporation at a temperature of less than 40° C. is based on hydrophobic polymer particles having a core/shell structure. The particles consist of 70 to 90% by weight of at least one polymer with a soft character having a glass transition temperature of less than 20° C. forming the core, and 10 to 30% by weight of at least one polymer with a hard character having a glass transition temperature of greater than 50° C. forming the shell. When applied to any surface and after drying at low temperature, the latex, without the use of any coalescents or volatile organic compounds, provides a continuous film which is homogeneous, has no surface tack and has good mechanical integrity.
