Abstract: Disclosed herein are compositions comprising oolitic aragonite particles, wherein the oolitic aragonite particles have an average particle size of between 100 nm to 1 mm, and a Hunter brightness level greater than 88. Further disclosed herein are personal care and/or cosmetic compositions, comprising a carrier and the aforementioned oolitic aragonite particles. Further disclosed herein are methods of making and using the oolitic aragonite particles.

Abstract: An electrodynamic vibration test system, also referred to as a shaker apparatus, includes many components but the transmission of vibration to a unit under test is limited to three while testing is performed in the horizontal mode and only two key items in the vertical mode. In the horizontal test mode, the armature is mechanically joined to a driver bar which is also mechanically connected to a slip plate. In the vertical mode the moving parts include a head expander mechanically connected to an armature. With the use of composite materials for the moving elements, total weight is decreased by fifty percent or more resulting in a power usage decrease while simultaneously increasing force capability.

Abstract: The described physiology sensor is worn on a single finger to capture one or more different physiological signals and has a sensor body including first and second raised mounds, protruding from its surface and being longitudinally spaced-apart such as to define a transverse air gap therebetween. The mounds each retain electrodes which abut palmar surfaces of the single finger. The sensor also has one or more physiological sensing devices housed within the body, including a skin conductance sensing device. The sensor can also have at least one of a temperature sensing device, and a photoplethysmography sensing device. A processor is housed within the body and communicates with the electrodes and the sensing devices to apply an electrical excitation thereto, and to process the physiological measurements.

Abstract: A traction device for relieving back pain has a flexible strip (1) which is held around a person's waist by a belt (2). Two adjustable straps (3) are attached at one end to the belt (2) and are provided with stirrup loops (12) at their opposite ends. The stirrup loops (12) fit around the person's feet and the person can self-apply a traction force to his spinal column by extending his knees.
