Abstract: A volume of a patient can be mapped with a system operable to identify a plurality of locations and save a plurality of locations of a mapping instrument. The mapping instrument can include one or more electrodes that can sense a voltage that can be correlated to a three dimensional location of the electrode at the time of the sensing or measurement. Therefore, a map of a volume can be determined based upon the sensing of the plurality of points without the use of other imaging devices. An implantable medical device can then be navigated relative to the mapping data.

Abstract: A cup holder assembly for a child seat movable between a retracted position and an extracted position includes an inner cup holder bracket, a medial cup holder slide movably attached to the cup holder bracket, and an outer cup holder floor pivotally attached to the cup holder slide. The cup holder slide and the cup holder floor move along an arc relative to the cup holder bracket, and the cup holder floor rotates relative to the cup holder slide and the cup holder bracket. The cup holder bracket has a rail guide and the cup holder slide includes a corresponding rail operable for slidingly engaging the rail guide. The cup holder slide further includes a lip that engages a corresponding ledge on the cup holder floor to rotate the cup holder floor as the cup holder slide is moved from the retracted position to the extracted position.

Abstract: Liquid crystal compositions that exhibit little or no toxicity with respect to cells include liquid crystals with chemical functional groups such as fluorine atoms, fluorophenyl groups, or difluorophenyl groups. Liquid crystals with little or no toxicity to cell lines may be added to cell culture media or added to components used in cell culture media. Cells may be grown in cell culture media that includes liquid crystals that exhibit little or no toxicity to cells.
