Abstract: A dynamic differential diagnosis training and evaluation system incorporates a beginner student learning mode, a beginner student test mode, an advanced student learning mode, and an advanced student test mode for training, nurturing, and evaluating dynamic differential diagnosis (dynamic DDx) reasoning skills for patient condition determination. In a preferred embodiment of the invention, the dynamic differential diagnosis training and evaluation system incorporates one or more computerized user interfaces for displaying, choosing, and interacting with a simulated virtual patient, hypotheses selections for the patient condition determination, simulated physical exam selections, simulated medical test selections, simulated medical test results, a computerized expert's feedback and answers, and an iterative differential diagnosis (DDx) list modification and refinement process that simulates real-life dynamic differential diagnosis (dynamic DDx).

Abstract: A healthcare content authoring software platform incorporates a healthcare education content authoring assistant software with interactive suggestion interface to assist a healthcare education content author in creating computerized healthcare education contents.

Abstract: A healthcare education software, which is executed by an electronic healthcare education system, incorporates a medical content authoring software platform with a medical authoring interface, a medical training, simulation, and evaluation software platform with a virtual patient examination simulator and an interactive prediction table, and a computerized medical causal concept diagram construction and evaluation software platform with corresponding interfaces for training of medical students and other healthcare professionals. Preferably, the healthcare education software is connected to a robust medical information database that contains a wealth of physiological simulation animation files, evidence-based patient diagnostic information, and other pertinent medical information, which can be readily imported and utilized by a healthcare education content creator in creating and updating medical training contents via the medial authoring interface.

Abstract: Bearings in a motor or bearing cartridge are positioned relative to the shaft and an outer sleeve, and a bearing retainer is then pressed against the outer races of one of the bearings in order to hold the bearings in position and preload the bearings in a desired orientation. The bearing retainer is chilled to a temperature significantly different than the sleeve with which it cooperates; shrinking the retainer to a size where it may be slip fit within a sleeve or other means for supporting the bearings in place. The retainer is then pressed against the outer races of the bearings, and held in place while it returns to the temperature of the sleeve within which it is fit. In this way, the preload is defined and maintained for the long term, as the retainer is pressed tightly against the outer race of the bearings; and the retainer is held within the sleeve as it returns to the same temperature being chilled is eliminated.

Abstract: A disc drive includes a disc drive motor for rotating a storage disc. The motor includes a motor base which carries a wiring assembly having a plurality of electrical contacts. A rotor hub is rotatably coupled to the base and rotatably carries a storage disc. The rotor hub includes a permanent magnet. A stator assembly includes a plurality of stator windings adapted for operation with the permanent magnet of the rotor hub. A wire guide coupled to the stator assembly positions wires of the stator windings adjacent the electrical contacts of the wiring assembly. The wires are soldered to the contacts after which the wiring guide can be removed. The stator assembly can be "potted" in an adhesive to reduce problems associated with resonant frequency of the disc drive motor. The wire guide acts as a retainer for the adhesive preventing the adhesive from interfering with rotation of the rotatable hub.
