This project explores the idea of implementing an electronic device that can melt away ice from frozen bike locks. It narrates the process of starting with no knowledge of how heating works and ending with a manufactured and soldered PCB with limited heating capability. Resistance heating and induction heating was studied in the initial phase of the project. Which proceeded into designing the complete schematic of the induction heater. A prototype was built which advanced further to the development of tools and ways to measure inductance, resonant frequency and temperature before the tests of the performance. When the performance tests were done the induction heater was optimized and later designed in eagle. A PCB circuit was ordered which later was soldered until completion.  The result was an induction heater in PCB form with limited functionality compared to the data of the prototype, due to faulty layout of the circuit. The performance of the end result was 20.02 degrees C to 33.20 degrees C in 11 minutes. The data from the prototype suggests that the induction heater can melt the ice from frozen bike locks since the performance was 21.96 degrees C to 62.02 degrees C in 4 minutes. Any rise in temperature over the boiling point of water 0 degrees C is good but tests in real winter conditions needs to be done to definitively confirm success. The mayor problem is whether a battery can provide with the required energy without getting to big or expensive. If the answer is yes then the induction heater of this project can be used regularly but the manufacturing costs would still be high.

Abstract For recent years, enterprises in Taiwan face the challenges of global competition. Most of Taiwan companies cannot compete with international companies on capital or scale. Thus cooperation with competitors or formation of strategic alliance become one of the best policy of reducing management and sales cost of entering new market and business risks. For the small-and-medium size enterprises which own unique skills but are lack of resources and new technologies, it could be the niche of entering global market to obtain transfer of technologies and management skill from superior internationalized enterprises. Door lock manufacturing industry is an absolute conservative industry. From the ancient year, due to security concern, it was a family inherited business. Through technology breakthrough and industrial revolution, it gradually turns into a mass production industry. Like most of the other industry, in recent years, Taiwan was developed to be an important manufacturing base of the global door lock industry. This thesis adopted the exploring methodology. It conducted its study based on the industrial analysis. It analyzes the door lock industry through horizontal analysis ¡V competitor analysis and vertical analysis ¡V supply chain analysis. It further create the following assumptions based on the resources interdependence theory, transaction cost theory and Porter¡¦s five forces analysis: 1. The motivation of strategic alliance is based on the resources interdependence theory. 2. The selection of partner in the strategic alliance is based on the transaction cost theory. 3. The objectives of strategic alliance are based on Porter¡¦s five forces analysis. Based on the above assumptions, this study conducted analysis on the strategic alliance project in between Taiwan Fu Hsing Industrial Co. Ltd. and Ingersoll Rand Group of companies. Through in-depth interviews with management executives from both companies, this study build up a model confirming the above assumptions. Further more, this thesis also present a series of recommendations to both companies in hope of leading this strategic alliance project into a win-win situation. Key words: Strategic alliance, Door lock industry

The object of this research is to develop robust wire-line systems which demonstrate high performance while simultaneously consuming low power. The main focus of this work is the Clock and Data Recovery (CDR) system, which is the primary circuit of any modern wire-line transceiver. Different techniques starting from circuit-level to system-level have been investigated in this work to improve the performance of multi-gigabit CDRs. A 62 GHz bandwidth amplifier has been presented to address the need for a scalable amplifier for CDR needs. A new technique has been proposed to improve the radiation immunity of latches, to reduce the BER in CDRs occurring due to package radiations. An injection-lock based clock recovery method was investigated as an alternative to PLL based CDRs as they can be used for burst-mode wire-line communication. The investigation yielded the vulnerability of the method to jitter (false-locking and high jitter transfer), the attenuation of which is critical to commercial CDRs. A novel false-lock detector system has been proposed and demonstrated for the first time as a robust solution to the issue of false-locking of CDRs due to repetitive patterns. The implementation of the final CDR system required the use of an L-C tank VCO, the components of which are generic for all commercial CDRs. A new systematic layout technique for the VCO has been proposed and demonstrated in this work to substantially improve the layout area and the associated parasitics, approximately by 70 %. This new layout addresses a critical yet often neglected part of VCO design. Furthermore, a new concept has been proposed to optimize static dividers with respect to their power consumption and number of devices.

International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / The XL-L Two-axis Pedestal is a novel adaptation of an existing design using a cross elevation over elevation axis configuration. This design affords full hemispherical coverage without gimbal lock (keyholes). In addition, the system provides continuous coverage without the necessity of rotary joints and sliprings. The design is ideally suited for shipboard systems, but is equally advantageous for any tracking mission where the target can approach a zenith gimbal lock or keyhole.

Thesis advisor: Andrew Beauchamp / Thesis advisor: Mathis Wagner / This dissertation considers changes of health insurance system of United States that affect health outcomes and labor market outcomes of population. The first chapter examines how Medicaid policy aimed to improve health status of low-income parents affects the health outcomes of young children. Estimates from variations in Medicaid rules across states and over time, show that there exist positive spillover effects on children from Medicaid expansions targeting parents. The child mortality declines more in states with higher level of generosity in Medicaid policy and the effect is larger among black children. Simulations indicate that recent Medicaid expansion under Affordable Care Act Reform can deepen the existing child mortality disparity across states due to different adoption of Medicaid expansion for low income adult population. The second chapter examines Massachusetts health care reform and its impact on labor market outcomes of older males approaching retirement. I find that older males are more likely to remain in full-time employed status rather to choose early retirement, and part-time employment increased only among low-income population who are eligible for subsidized health insurance. The results suggests that there exists employment-lock effect from increase of employers providing employersponsored health insurances following the reform. / Thesis (PhD) — Boston College, 2015. / Submitted to: Boston College.

Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process. The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix. A model of the selected concept was made in SolidWorks and eventually built as a prototype. The result of the project was a mechanism where the lid open and close by a vertically moving block, on the back of the device. The linear movement of the block is aquired through the rotation of a screw, driven by an electrical motor. The mechanism was tested against the company's requirements and showed satisfying results in all areas except for durability. The reason is believed to be the change of components in certain parts of the prototype, due to demands on low cost. If these components were to be manufactured as the report suggests, the mechanism would be expected to gain durability and also meet the durability requirements.
