Abstract: A centrifuge may include a bowl operative to rotate with respect to a stationary portion. The centrifuge may include at least one vibration sensor operative to generate vibration data representative of vibrational movement of portions of the centrifuge. The processor may monitor the vibration data as the bowl is being filled with a fluid. The processor may cause a drive device to increase the rotational speed of the bowl responsive to determining from the vibration data that the bowl has becoming substantially filled with a fluid.

Abstract: Disclosed is a heater device for thermally welding suture strands, including: a substrate extending from a first end to a second end along a substrate axis, and having a substantially planar heater support surface; a joinder layer disposed on the heater support surface; a heater element extending from a first end to a second end along a heater axis thereof and disposed on the joinder layer, the heater element being a layer and being coupled to the support surface by the joinder layer; an electrical interface including a first electrically conductive element coupled to the first end of the heater element, and a second electrically conductive element coupled to the second end of the heater element.

Abstract: Vaporization of volatile materials while avoiding combustion and denaturation of such material provide an alternative to combustion as means of volatilizing bioactive and flavor compounds to make such compounds available for inhalation without generating toxic or carcinogenic substances that are by-products of combustion and pyrolysis.
