  • Patent number: 11400723
    Abstract: A method of engaging a supply module with a printhead includes the steps of: moving an actuator handle in a first motion along a first axis, thereby linearly sliding the supply module along the first axis towards the printhead and engaging ink couplings of the supply module with complementary ink ports of the printhead; and moving the actuator handle in a separate second motion along a second axis perpendicular to the first axis, thereby moving a PCB of the supply module towards the printhead and engaging PCB contacts with complementary printhead contacts.

  • Patent number: 11391832
    Abstract: A phase Doppler radar system may comprise a pulse Doppler receiver/transmitter (R/T) subsystem coupled with a processing subsystem. The system may determine target velocity and target detection events by collecting pulses from the pulse Doppler R/T subsystem, determine an undifferentiated phase of each of the pulses, differentiate the pulses, and determine a differentiated phase of each of the pulses. The system may perform a linear fit of the differentiated phases of the pulses to produce a slope and an intercept. The system may determine a set of initial estimates of coefficients of a nonlinear fit equation. The system may perform iterations of a nonlinear least squares fit, beginning with the initial coefficient estimates, to produce a non-linear fit result. The system may determine a goodness-of-fit (GoF) statistic associated with the nonlinear fit result, and declare a detection event when the GoF is superior to a GoF statistic associated Gaussian noise.
