Abstract: Disclosed are a method and a system for changing a database schema. The method comprises receiving a request to make a set of changes to a first version of the database schema of a database, and creating, based on the set of changes to the first version, a conversion rule for converting data records maintained by the database between the first version and a second version of the database schema. The second version results from the application of the set of changes to the first version of the database schema. The method further comprises storing the conversion rule for retrieval when performing data operations on the data records in accordance with any database schema version in a set of supported versions comprising the first version and the second version of the database schema. Also disclosed are methods and systems for performing data operations on databases supporting multiple versions of a database schema.

Abstract: A coated article includes a low-emissivity (low-E) coating. The low-E coating includes at least one infrared (IR) reflecting layer of a material such as silver, gold, or the like, and a dielectric overcoat designed to increase solar heat gain coefficient (SHGC) of the coated article. A dielectric undercoat may also be designed to increase SHGC of the coated article in certain example embodiments. In certain example embodiments, the overcoat and/or undercoat are designed to increase SHGC while also providing for desirably high visible transmission (TY or Tvis) and desirably low normal emittance (En).

Abstract: A battery replacement system that is capable of detecting and measuring the remaining life in at least two batteries. When the system detects that the level of battery performance falls below a first predetermined range relative to overall battery life, the system defines a cluster of batteries and replaces the cluster of batteries. The cluster of batteries is defined by at least first and second batteries being proximal to each other in terms of battery life and within a predetermined second range in respect to each other.

Abstract: An emergency controller for use with a medical device adapted to be controlled by a primary controller. The emergency controller including a control unit, a power source, a connector and a switch, and wherein the connector is adapted to allow the emergency controller to be connected to the medical device or to the primary controller, and wherein the switch is adapted to activate the control unit when the emergency controller is connected to the medical device.
