Solar Panel A/D Conversion Power Meter Micro-Controller Servo-motor
Description and Key Benefits: Solar Panel would move around and by current intensity analysis, would detect the most efficient position that yields the most power produced. Based on recorded time of first ambient light and time of max. power absorption during initial stationary period, initial direction of panel is calculated, and movement schedule is determined from this. Solar power is renewable energy source, maximizing its potential is necessary in times of high energy demand Does not require as much manual alignment and configuration, compared to another solar panels Power Source, User Interface: Power would come from the sun, solar panels would convert solar energy into electrical energy, which would then be used by the motors, power meters and processing unit Micro controller would be preprogrammed to perform auto alignment tasks, would inform user through website interface e.g. direction, angle of elevation etc Team Talent: Our team has good programming skills, knowledge in electronic circuit design and signal processing.

Proposed Product Summary
1 Slide to further describe the Proposed Selected Product High Level Definition User Requirements Bullet form plus optional pictures (competitive pictures) What exactly is the product? What is the primary benefit to the user? What is the intended application of the product? What claims can be made with regard to the product? Are there similar or identical products of this type on the market? What major industry family does the product belong to? (ie; aerospace, automotive, consumer, telecom, etc,)

Description: The project is intended for thermal management of next generation CT system. As we all know thermal management is a very important part of any design both from optimal functionality and reliability point of view. This document will describe the functionality of the controller. The detector thermal controller is designed to maintain rails at a uniform temperature, which is critical for controlling the photodiode and preventing any changes to the rail temperature profile. Changes in the rail temperature or the temperature profile can lead to IQ errors due to poor diode temperature control.

Ethics Considerations
For the recommended project, discuss the ethics issues below and create a slide indicating applicability and mitigation methods (ways to prevention) for each Quality and Safety Adequate Verification and Validation Ensuring legal compliance Conflict of interest Bribery and kickbacks Treatment of confidential or proprietary information Consideration of the employer’s assets Relationships; clients, consultants, competitors, and contractors Gifts, meals, services, and entertainment Environmental Damage Outside employment/business activities
24
Ethics Considerations
Quality and Safety We will use UL listed components Adequate Verification and Validation We will have our data independently verified by another team member Ensuring legal compliance We will research prior patents and compliance with current safety standards Conflict of interest Not applicable Bribery and kickbacks We are not worth bribing Treatment of confidential or proprietary information Environmental Damage We will use ROHS compliant devices Outside employment/business activities We will complete all work internally
