  • Patent number: 12235237
    Abstract: An embodiment provides a method for measuring a component of an aqueous sample using square wave modulation, including: introducing the aqueous sample to a chamber of a square wave modulation apparatus; applying a stimulus voltage step to the aqueous sample, wherein the stimulus voltage comprises a staircase voltage, wherein each step of the staircase voltage defines a group, wherein the group comprises one or more square wave modulation cycles; adjusting a time acquisition window, wherein the time acquisition window is a portion of each of the half cycle of the stimulus voltage; measuring a resultant current output resulting from the stimulus voltage within the time acquisition windows; and averaging the resultant current output across at least one or more cycles of each group. Other aspects are described and claimed.

  • Patent number: 12226894
    Abstract: A tool interchange for a submersible remote operated vehicle (ROV) arm includes a first interchange body that affixes to an ROV arm. A second interchange body is carried by the first interchange body to rotate on a rotation axis. The second interchange body includes a tool mount actuable between gripping an ROV tool to the second interchange body and releasing the ROV tool from the second interchange body. An inductive power coupling part is provided in the tool mount. The inductive power coupling part is presented outwardly in the tool mount opposite the first interchange body, resides on the rotation axis and is fixed with respect to the first interchange body while the second interchange body rotates. The inductive power coupling part is adapted to inductively communicate power with a corresponding inductor power coupling part of the ROV tool when the ROV tool is docked in the tool mount.

  • Publication number: 20190133832
    Abstract: An absorbent, self-adhesive nipple cover for absorbing fluids from a lactating woman's nipple while concealing the nipple and areola in such a way so as to flatter the appearance of the woman's breast for intimate wear or to disguise that the woman is nursing. The inner layer, facing the woman's breast, is comprised of two sections: a central section made of absorbent material, and a perimeter section made of one or more adhesive appendages that secure the nipple cover completely to the woman's breast. The outer layer, facing away from the woman's breast, is comprised of protective aesthetic material to prevent fluids from leaking through the absorbent material onto clothes or other materials that may come into contact with the nipple cover, and to promote the appearance of the woman's breasts while concealing the nipple and areola.
