Abstract: A livestock head holder for a head gate features a top holding member, a bottom holding member and an intermediate link connecting same, of which the intermediate link occupies an over-centered locking position in a fully open state of the head holder to prevent gravitational dropping of the top holding member. The head holder is infinitely adjustable in its installed height on the head gate, via use of tightenable clamps that engage through a slot between bars of a skeletal gate panel to make clamping embrace against a rear side of the head gate bars at any user-selectable heigh along the slot therebetween.

Abstract: Described herein are X-ray-based CT systems, specifically those with a stationary X-ray source and a moving object of interest, and methods of using the same, that address limitations in current stationary-source CT, such as scatter contamination and limited scan trajectories. The described systems include a pre-object collimator to form a narrow beam. Scatter contamination is reduced to less than 5% of acquired projections, resulting in high-quality CT images with minimal artifacts, improving diagnostic accuracy and measurement precision. The described system also allows for nonplanar trajectories, providing complete sampling of an object along multiple degrees of freedom.

Abstract: The present invention refers to an electrochemical sensor for determining the presence and/or the concentration of a target analyte in an aqueous solution, comprising: a front electrode comprising pores permeable to the aqueous solution and comprising a sensitive surface to the target analyte; an electrolytic conductor bridge permeable to the aqueous solution; and a back electrode comprising at least a surface and optionally a support. The front electrode and the back electrode are electrically connected via the electrolytic conductor bridge and the front electrode comprises pores above 0.2 pm of equivalent diameter that connect the external surface of the front electrode and the electrolytic conductor bridge. The electrochemical sensor is configured so that the aqueous solution enters in contact with the back electrode through the electrolytic conductor bridge, which in turn enters in contact with the aqueous solution through the pores of the front electrode.

Abstract: A handwheel actuator for a steer by wire system may include a feedback actuator and a column for operably coupling a handwheel to the handwheel actuator. The column includes a column shaft extending from a first end of the column to a second end of the column. The feedback actuator is operably coupled to the second end of the column and provides tactile feedback to an operator responsive to movement of the handwheel. The feedback actuator includes a torsion bar coaxial with the column shaft. The column shaft is supported relative to a housing of the column by a first column shaft bearing disposed proximate to the first end of the column and a second column shaft bearing disposed proximate to the second end of the column. The torsion bar extends into the column shaft past the second column shaft bearing and is operably coupled to the column shaft via a removable fastener disposed at a portion of the torsion bar that extends past the second column shaft bearing.
