  • Patent number: 10379021
    Abstract: A pallet impact station includes a frame, at least one pendulum swing arm rotatably coupled to the frame, and a carriage assembly carried by the at least one pendulum swing arm. A latching mechanism extends between the frame and the at least one pendulum swing arm, and engages the at least one pendulum swing arm when the carriage assembly is in a lowered position, raises the carriage assembly to a raised positon, and disengages the at least one pendulum swing arm at the raised positon so that the carriage assembly strikes a pallet. A sensor generates a signal corresponding to how high the carriage assembly is raised. A controller operates the latching mechanism, including disengaging the at least one pendulum swing arm when a height of the carriage assembly corresponds to a desired release height so that a predetermined impact force strikes the pallet.

  • Patent number: 10345278
    Abstract: A pressure sensor and its use for visually determining whether a preselected pressure threshold has been achieved, for example during high pressure processing treatment of a foodstuff. The pressure sensor includes a contained color-changing system having a dye, a developer, and a solvent; upon achievement of the preselected pressure threshold, the dye and the developer interact, resulting in a visible color change. Further, the visible color change can be retained upon a decrease in pressure and upon an increase in temperature, thereby effectively recording the achievement of the preselected pressure threshold during the high pressure processing treatment.

  • Patent number: 10309852
    Abstract: Apparatus and associated methods relate to generating redundant measurement of pseudo differential pressure using two absolute-pressure sensors, each exposed to a different environment. Each of the two absolute-pressure sensors has complementary first and second output nodes. The first output node has a positive relation with and/or response to increasing pressure, while the second output node has a negative relation with and/or response to increasing pressure. A first difference measurement signal is calculated based on a difference between the positive relation output signals of the first and second absolute-pressure sensors. A second difference measurement signal is calculated based on a difference between the negative relation output signals of the first and second absolute-pressure sensors. Both the first and second difference measurement signals are indicative of a pressure difference between the first and second environments.
