    Abstract: A production system such as an inkjet printer system includes a plurality of communication distribution devices connected in a daisy chain arrangement. A plurality of secondary devices, such as printhead electronics boards for inkjet printheads, is connected to each of the communication distribution devices. A first communication distribution device which is connected to a system controller assigns a communication address to itself from a first set of communication address and assigns communication addresses to its connected secondary devices from a second set of communication addresses. It then communicates information to the next communication distribution device specifying the next available communication addresses. This process continues down the chain of communication distribution devices. The assigned communication addresses are then transmitted to the system controller.

  • Patent number: 10284286
    Abstract: A multiuser communication system comprises multiple transmitters and a multiuser receiver that detects multiple transmissions via iterative soft interference cancellation. An initial acquisition module and single user decoder module are also described. The multiuser receiver acquires and subtracts known users in the residual signal before acquiring new users in the residual signal, which is performed iteratively until no new users are detected or a stopping criterion is met. To aid receiver acquisition, the transmitters insert discrete tones into the transmitted signals. These allow the multiuser receiver to obtain initial estimates of the frequency, time, gain, and/or phase offset for each user. To improve the quality of cancellation the receiver refines estimates of gain, time, frequency and phase offsets for each user after each iteration, and calculates time varying SINR estimates for each user. The multiuser receiver may be satellite based, may be a distributed receiver, or process users in parallel.
