Abstract: Embodiments of the invention relate to systems and methods for creating a form for receiving data relating to a health care incident. A dictionary of field objects is provided in a metabase, where a field object defines attributes, and an instance of a field object is a form field. A request to create a user-defined field object is received and it is determined that the user-defined field object is not in the dictionary of field objects in the metabase. The user-defined field object is generated by defining attributes for the user-defined field object, where at least one attribute is a presentation attribute for a form field within a form. The user-defined field object is added to the dictionary of field objects in the metabase and the user-defined field object is linked to a data location in a persistent store.

Abstract: A slide-block-type shaft linear motor platform includes a mover and a stator. An air gap is defined between the mover and the stator. The air gap can communicate with outer side via a fluid inlet space. Accordingly, air convection can take place between the heat source, that is, the winding inside the mover and the outer side. Therefore, the heat generated by the winding can be continuously dissipated to prevent the components from deforming due to the heat. In this case, the precision of operation can be ensured and the performance of the motor will not deteriorate due to the heat.
