Abstract: A modifiable pinball machine includes a processing device, a memory storing instructions executable by the processing device, a communications interface coupled to the processing device for receiving new music data from a source external to the pinball machine for storage in the memory, and a speaker coupled to the processing device for playing music retrieved from the memory. The new music data is provided with data useable by the instructions to cause the processing device to automatically retrieve from the memory the new music data in lieu of originally provisioned music data, for playing via use of the speaker, when the pinball machine is caused to operate in a predetermined operating state.

Abstract: An illuminated mirror includes a central reflective mirror portion and a surrounding transmissive portion supported to a housing. Spacing between an outer diameter of the transmissive portion and the housing allows airflow to exit from the housing. A chamber behind the mirror surface may comprise a dish reflector surface. In one form, the dish reflector comprises a white enamel surface. Lamps, which may comprise LEDs, are mounted to the reflector surface. The LED lamps may be placed in a pattern on the reflector surface. Circuitry may be provided to illuminate either all or selected ones of the LEDs. Lamps of selected colors may be provided. Preselected combinations of lamp illumination vary the level and composite color of illumination. In order to enhance the comfort of a user, a fan may be positioned in the housing behind the reflector. A cooling device may cool airflow from the fan.

Abstract: A method for determining a market clearing price (“MCP”) in an electricity market, in which an objective function relates the MCP and constraints in terms of a nonlinear programming expression, and the MCP is found by resolving an augmented Lagrangian dual function using a surrogate optimization framework. A system is also provided.

Abstract: A method for determining a market clearing price in an electricity market, subject to a plurality of constraints, comprising the steps of defining an objective function relating the MCP and constraints in terms of a nonlinear programming expression, applying Lagrangian relaxation to the nonlinear programming expression to form a Lagrangian dual function; adding penalty terms to the Lagrangian dual function to form an augmented Lagrangian dual function; resolving the augmented Lagrangian dual function using a surrogate optimization framework comprising repeating, until stopping criteria are satisfied, the steps of forming one or more supply sub-problems and an MCP sub-problem; optimizing the MCP sub-problem while keeping all other variables at their latest available values; optimizing at least one of the one or more supply sub-problems while keeping all other variables at their latest available values; updating multipliers used to relax constraints; determining the MCP in accordance with the resolved augmented
