The invention features methods and apparatuses for determining replacement of components in liquid pressurization systems. A replaceable component for use in a pump of a liquid pressurization system includes a body portion and a data storage mechanism. The data storage mechanism is in physical contact with the body portion. The data storage mechanism is configured to communicate information to a reader of the liquid pressurization system. The information is usable to determine a condition of replacement (e.g., a remaining usable life) of the replaceable component.

Apparatus for generating a pulsating pressurized fluid jet are disclosed. One disclosed example includes a line system having at least one nozzle with at least one nozzle orifice from which a pulsating fluid jet of pressurized fluid emerges, and a chamber having a pressure wave generating device to generate fluid pressure waves, where the chamber is in fluid communication with the line system through an outlet opening for the generated fluid pressure waves. The disclosed example also includes a setting device for controlling the amplitude of the fluid pressure waves in the line system upstream of the at least one nozzle orifice where the setting device sets a quotient of a path length of the fluid pressure waves between the outlet opening and the at least one nozzle orifice, and the wavelength of the fluid pressure waves in the line system.

The system and method described herein generally pertains to generating a lead in profile that defines acceleration before a cutting velocity is achieved to perform a cutting operation and a lead out profile that defines deceleration after the cutting operation is performed. The lead in profile defines acceleration from approximately zero (0) to the cutting velocity within a duration of time in order to perform the cutting operation, wherein the lead in profile is calculated based on the cutting velocity or a type of material of the workpiece, a start location for the cutting operation, and a thickness of the workpiece. The lead out profile defines deceleration from the cutting operation to approximately zero (0) within a duration of time, wherein the lead out profile is calculated based on the cutting velocity or a type of material of the workpiece, an end location for the cutting operation, and a thickness of the workpiece.

Waterjet systems including control valves and associated devices, systems, and methods are disclosed. A waterjet system configured in accordance with a particular embodiment includes a fluid source, a jet outlet, and a fluid conveyance extending from the fluid source to the jet outlet. The system further includes a control valve positioned along the fluid conveyance downstream from the fluid source and upstream from the jet outlet. The fluid conveyance has a first portion upstream from the control valve and a second portion downstream from the control valve. The control valve is configured to controllably reduce a pressure of fluid within the second portion of the fluid conveyance relative to a pressure of fluid within the first portion of the fluid conveyance. The first portion of the fluid conveyance is configured to accommodate movement of the jet outlet relative to the fluid source.

Devices and methods for processing animal or human tissue are provided. The devices may include a vacuum surface to secure the tissue in place and an apparatus for removing fat or other material from the tissue. The apparatus can include one or more blades and/or a fluid jet system.
