Abstract: The present disclosure generally relates to auditory nerve stimulation to create the perception of sound in the brain of a subject such as an animal or human being. In one form, a system includes an implantable electrode array including a plurality of spaced apart micro-needles. The system also includes a first electrical lead electrically coupled to and extending from the implantable electrode array, and an auditory signal device configured to produce one or more electrical signals representative of communications received from an external processor. An interposer is configured to electrically couple the implantable electrode array and the auditory signal device in an arrangement where one or more electrical signals produced by the auditory signal device may be transmitted through the first electrical lead to the implantable electrode array. Various novel stimulation strategies can be employed, such as place modulated stimulation signals.

Abstract: Novel compounds, compositions, and methods of using and preparing the same, which may be useful for treating alpha-1 antitrypsin deficiency (AATD).

Abstract: A mobile concrete mixing unit has an aggregate bin divided into two compartments by a water tank provided within the aggregate bin. A hydraulic reservoir is provided within the water tank in order to cool the hydraulic fluid within the hydraulic reservoir and warm the water within the water tank. The water tank also helps to keep the aggregate warm and flowable when used in low temperatures. A lower portion of the water tank includes sides that slope inwardly so that aggregate within the bin can drop freely onto a conveyor belt without bridging between the water tank and the sidewalls of the aggregate bin.

Abstract: A volumetric concrete mixer includes a monitoring and control system that assures a uniform amount of cement per unit of aggregate. A processor is in communication to receive an input of a weight of a cement bin from a cement bin load cell and in communication to receive an input of a number of rotations of a conveyor from an aggregate sensor. The processor is adapted to determine a rate of change of weight of the cement bin over a set number of rotations of the conveyor, and to instruct the cement dispenser to adjust the cement dispenser speed to maintain a constant rate of cement being dispensed from the dispenser bin to the mixing area per the set number of rotations of the conveyor.
