Abstract: A method of treating selenium-containing wastewater comprises performing anoxic biological treatment of the selenium-containing wastewater to produce a first liquid including a residual dissolved selenium species, introducing an oxidant into the first liquid to form an oxidant-treated first liquid, introducing a coagulant into the oxidant-treated first liquid to form a second liquid having selenium-containing solids, and removing the selenium-containing solids from the second liquid in a solids-liquid separation operation.

Abstract: A position controller for electronically monitoring the position and speed of a dredge. The position controller consists of an electric powered line winding spool with an electric encoder to indicate line speed and position to a microprocessor. A drag control assembly with electric control is used to increase, decrease or set the drag at desired setting by microprocessor control. Touch screen microprocessor interface is the preferred method to enter settings into the system and allow display/control through multiple preexisting marine electronic devices throughout a fishing boat.

Abstract: A perineal heating pad includes a central portion and two opposing end portions. The central portion includes a heating element disposed on or within the heating pad and the opposing ends may include one or more tabs extending outward from the central portion. A non-stick adhesive is used to secure the heating pad to the perineal body tissue of the patient and a controller supplies heat to the heating element and maintains the perineal tissue of a patient at a desired temperature.

Abstract: The present invention relates to devices for detecting esophageal state changes. More specifically, the present invention relates to a lightweight, portable, user-operable device capable of detecting gastroesophageal reflux events. The sonography array can also be used to track the frequency of gastroesophageal reflux events, and can either store or deliver the data either to a practitioner's server or to a user's electronic device.
