Noise And Vibration Reduction Of A Clothes Dryer, Daniel O'Hare
Noise And Vibration Reduction Of A Clothes Dryer, Daniel O'Hare
Honors Theses
As placement of washers and dryers becomes common in apartment buildings and high rises, noise generated by the dryer becomes a nuisance to the inhabitants. Whirlpool Corporation is experiencing this issue first hand with their Horizon model long vent dryers. A focus was placed on noise and vibrations caused by the dryer motor, because its vibrations are transferred throughout the structure of the dryer. The motor causing sound problems was a modified motor from the standard model, including a speed-increasing attachment in order to operate the fan at an increased speed. Through sound and vibration measurements, structural and airborne noise …

Industrial Wireless Communication System For Notification, Jolica Dias, Devin Semrau, Jumana Abukabbos
Honors Theses
An industrial wireless communication system for short structured messages was needed to support lean manufacturing environments. While first generation prototypes of end devices were previously constructed for the network, it lacked the range, robustness and battery operation desired. The advances made in the new system incorporate multiple small rechargeable user modules that communicate with and through one or more higher powered fixed location message router stations. This configuration ensures that wireless signal integrity is maintained throughout an industrial facility, and that the messages are successfully sent and received. XBee wireless transceivers were imbedded onto the router to enable communication between …

Plug-In Hybrid Vehicle (Phev) Component Pre-Heater, Ria Pereira
Honors Theses
In plug-in hybrid electric vehicles, the optimum temperatures of the cabin and various fluids are achieved through the dissipating heat of the internal combustion engine. In colder climates the initial warm-up of components requires the internal combustion engine to run causing unnecessary consumption of fuel. This project improved the pre-heating system formerly in place. It uses a variety of electric heaters along with the positive temperature coefficient (PTC) heater and blower motor already installed on the vehicle. A system utilizing a microcontroller turns the heaters on and off based on the inputs from the temperature sensors installed on the vehicle. …
