Abstract: Some embodiments provide irrigation generator systems that include a main conduit comprising an inlet conduit and an outlet conduit; a flow control system positioned within the main conduit; a generator conduit comprising a generator inlet conduit and a generator outlet conduit, wherein the generator inlet conduit is fluidly coupled with the main conduit upstream of the flow control system, the generator outlet conduit is fluidly coupled with the main conduit downstream of the flow control system; and a generator comprising a rotor assembly cooperated with generator conduit to be physically activated by a flow of fluid through the generator conduit causing rotation of the rotor assembly and generates electrical power. The flow control system transitions between a closed state to the open state in response to a water pressure exceeding a pressure threshold.

Abstract: A method for determining motional branch current in an ultrasonic transducer of an ultrasonic surgical device over multiple frequencies of a transducer drive signal. The method may comprise, at each of a plurality of frequencies of the transducer drive signal, oversampling a current and voltage of the transducer drive signal, receiving, by a processor, the current and voltage samples, and determining, by the processor, the motional branch current based on the current and voltage samples, a static capacitance of the ultrasonic transducer and the frequency of the transducer drive signal.

Abstract: A surgical instrument operable to sever tissue includes a body assembly and a selectively coupleable end effector assembly. The end effector assembly may include a transmission assembly and an end effector. The body assembly includes a trigger and a casing configured to couple with the transmission assembly. An information transmission system transmits instrument information received from a sensor, for example, to a secure server via a secure gateway connected to the instrument. The instrument may be previously tested on a calibration kit to pre-determine and load surgeon-specific settings onto the instrument prior to use.

Abstract: A combined container and date-notification mechanism includes a container that has a body and a lid removably attached thereto for maintaining the perishable food item isolated from the environment. A mechanism is included for identifying a date when the perishable food item is placed inside the body such that a user can quickly identify a number of days that the perishable food has been housed within the container without removing the lid from the body. An identification marker is adjustably connected to the date-identifying mechanism and is spaced from the affixing mechanism. A mechanism is included for removably affixing the date-identifying mechanism onto the lid such that the user can selectively affix the date-identifying mechanism onto alternate containers. The affixing mechanism is formed from water insoluble material.

Abstract: A fluidizing apparatus, such as a winterizing apparatus, and related method for preventing freezing of water in the water pipes of a dwelling. The apparatus includes a pump, an inlet line, an outlet line, a pressure switch, and an air compressor tank. The outlet line is connected to a faucet of the water pipes of the dwelling and the inlet line is positioned in a container of fluid, such as antifreeze. When a second faucet is opened, the pump is activated, and the pump will then cause antifreeze to flow from the container, through the inlet line, the pump, and the outlet line, and then into the faucet and through the water pipes of the dwelling. An associated air compressor tank is in fluid communication with the pressure switch and exit line, and cooperates with the pressure switch to maintain consistent pumping of the antifreeze. After antifreeze is in the pipes, a shut-off valve in the exit line is closed and/or the at least one valved water outlet is closed, which causes the pump to deactivate.
