Design Technique for Analog Temperature Compensation of Crystal Oscillators

Haney, Mark Allan 28 November 2001 (has links)
For decades, the quartz crystal has been used for precise frequency control. In the increasingly popular field of wireless communications, available frequency spectrum is becoming very limited, and therefore regulatory agencies have imposed tight frequency stability requirements. There are generally two techniques for controlling the stability of a crystal oscillator with temperature variations of the environment. They are temperature control and temperature compensation. Temperature control involves placing the sensitive components of an oscillator in a temperature stable chamber. Usually referred to as an oven-controlled crystal oscillator (OCXO), this technique can achieve very good stability over wide temperature ranges. Nevertheless, its use in miniature battery powered electronic devices is significantly limited by drawbacks such as cost, power consumption, and size. Temperature compensation, on the other hand, entails using temperature dependent circuit elements to compensate for shifts in frequency due to changes in ambient temperature. A crystal oscillator that uses this frequency stabilization technique is referred to as a temperature-compensated crystal oscillator (TCXO). With little added cost, size, and power consumption, a TCXO is well suited for use in portable devices. This paper presents the theory of temperature compensation, and a procedure for designing a TCXO and predicting its performance over temperature. The equivalent electrical circuit model and frequency stability characteristics for the AT-cut quartz crystal are developed. An oscillator circuit topology is introduced such that the crystal is operated in parallel resonance with an external capacitance, and equations are derived that express the frequency stability of the crystal oscillator as a function of the crystal's capacitive load. This relationship leads to the development of the theory of temperature compensation by a crystal's external load capacitance. An example of the TCXO design process is demonstrated with the aid of a MATLAB script. / Master of Science

A Research of Legal System of State Compensation Liability¡VTake Cases of State Compensation of Kaohsiung City Government Police Bureau as Example

Kuo, Yin- Ching 05 September 2006 (has links)
Basically, state compensation liability can be sorted to: One is caused by the public servant who exercises public power while executing duties(namely human liability) and the other is caused by deficient installation or management of public-owned and public facilities (namely liability of an object). They are two pivots related to compensation liability of the existing State Compensation Law. Although cases of Kaohsiung City Government Police Bureau are increasing year by year during the enforcement of State Compensation Law for more than twenty years, all of them are from lawless liability of public servants and deficient liability of public-owned and public facilities. The research is mainly to analyze and discuss cases of state compensation of Kaohsiung City Government Police Bureau and targets are police officers of Kaohsiung City Government Police Bureau as the priority. Concerning general public servants of other organizations and ¡§public servants having duties of judgment and prosecution,¡¨ they belong to special regulation of State Compensation Law, so they are not within the scope of the research. To pursue accuracy and precision, the research analyzed cases of state compensation of Kaohsiung City Government Police Bureau during recent five years (2001 to 2005) to discuss whether there is room for improvement among five structures of our legal system of state compensation liability, including principles of legislation, organizational structure, authority design and application, relief & aftercare, and supervision & evaluation, and then provide Kaohsiung City Government Police Bureau with concrete ways and suggestions in handling cases of state compensation in the future.

A legal comparison between South African, Canadian and Australian workmen's compensation law

Jansen van Vuuren, Johanna Petronella 04 1900 (has links)
Workers’ compensation originated internationally because of the need to address the plight of workers and communities left destitute due to occupationally sustained disabilities or death. This study examines how the right to no-fault compensation developed in South Africa in comparison to the comparable law in Canada and Australia. Specific limitations regarding the right to workers' compensation pursuant to the South African compensatory laws were identified. Limitations identified include the persons falling within the ambit of the law, circumstances creating a right to compensation, the right to claims for increased compensation uniquely provided for in South African compensatory law and founded in the negligent conduct of employers as well as common law redress for damages. The background of the administrative remedy in the form of the right to compensation for occupational injuries and diseases ought to be seen in the light of the Constitution of the Republic of South Africa 1996. / Mercantile Law / LL.M.

Způsob a rozsah náhrady škody / Mode and scope of damages

Janurová, Petra January 2016 (has links)
in English This diploma thesis deals with the manner and extent of compensation for damage in civil law, which is systematically included in the fourth part of the Civil Code, entitled Relative property rights and in section named Obligations arising from torts. Specifically, the manner and extent of compensation for damage is defined in articles from 2951 to 2971. The thesis contains basic comparison of the conceptions of the manner and extent of compensation in the former Civil Code and in the new one, with emphasis on the most important reforms. It clarifies new terminology and describes the background of the newly established rules of law. It contains an analysis of the Czech legislation and its comparison with legislation of the neighboring states. It also mentions the European conception of the manner and extent of compensation for damage. The system of the thesis follows the organisation of the provisions on the manner and extent of compensation in the new Civil Code and is also divided into three chapters. The first one deals with compensation for material damage. Its main issue is the manner and extent of the material compensation and the conditions for its reduction. It also contains a provision on compensation for damage caused by an intentional criminal offence and rules for determining...

Destruction Fire Operation ¡XA Study on the Compensation Responsibility of Authorized Use and of Objects

LI, CHIH- TSAN 25 July 2005 (has links)
Two major pillars of the state responsibility system are administrative losses compensation system and national compensation system. The ¡§Destruction Fire Operation¡¨ which causes innocent third person¡¦s property loss forms administrative losses compensation responsibility or national compensation responsibility promptly. The fire protection law in Taiwan has been revised and enlarged the 19th item 2 since August, 1995. From the view of protecting people¡¦s right, it is admirable to compensate people propriety loss caused by disaster. However the related compensation stipulate seems not enough. The essay based on legal principle state responsibility researches the national compensation responsibility of the ¡§Destruction Fire Operation¡¨. Meanwhile, we confirm it is true that the theory and practice are agreed with from two cases happened in Kaohsiung county. The essay researches the motive, the range and restriction, the structure and method. We have detail description on the meaning of the ¡§Destruction Fire Operation¡¨ compensation responsibility as well as extended compensation responsibility resulted from fire-fighting. We analyze and discuss the current legal provisions of ¡§Destruction Fire Operation¡¨, and practices of fire operation compensation and compensation cases.

An Analytical Comparison of Domestic Relocation Compensation Practices with International Relocation Compensation Practices

Mills, LaVelle Harper 05 1900 (has links)
This research was designed to determine to what extent employees relocated domestically are protected financially by company practices and policies. Since international relocation has as its objective protecting employees from financial loss, these policies were used as a point of comparison in evaluating domestic relocation. The study was conducted through the use of a mail questionnaire survey of 326 randomly selected companies within the Fortune 500 top industrial organizations. A total of 153, 47 per cent, questionnaires were returned. This survey attempted to establish the basic policies that are applied by these organizations in domestic employee relocation.

A landowner's ability to negotiate compensation with the holder to rights to minerals / Richard William Draper

Draper, Richard William January 2014 (has links)
In 2002 the Mineral and Petroleum Resources Development Act 28 of 2002 (MPRDA) was promulgated to regulate the exploitation of minerals and petroleum in South Africa. With the promulgation of the MPRDA landowners’ rights regarding the minerals embedded in their land have been annihilated. South Africa’s mineral and petroleum resources were statutorily bequeathed to all the people of South Africa and the state was statutorily appointed as the custodian thereof for the benefit for all South Africans. All the rights to minerals have been severed from the ownership of land and the MPRDA does not recognise the existence of common law mineral rights as they existed directly before the MPRDA took effect. As a result thereof, landowners are not entitled to compensation for the loss of the minerals that are mined from the soil of their land. In addition, landowners ostensibly no longer possess the right to enforce negotiations regarding compensation for losses suffered or damages caused during the course of mining operations. It is against this background that this study seeks to determine to what extent the MPRDA or common law provide for the protection of landowners’ rights regarding compensation claims against the holder of statutory prospecting or mining rights for the infringement of their ownership brought about by mining activities on their land. / LLM (Estate Law), North-West University, Potchefstroom Campus, 2015

Thermocouple Measurements without Custom Electronics

Wanis, Paul 10 1900 (has links)
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Thermocouple measurements require “cold junction” compensation in order to obtain a correct reading. This compensation has traditionally been done with custom circuitry. In flight test applications where volume and power are at a premium (e.g. weapons flight test) it is desirable to have a more flexible solution that uses standard analog data acquisition channels already available as part of the encoder circuitry and performs compensation with remote software. This can be done via digital compensation, but certain measures must be taken to maintain accuracy and minimize noise. This paper describes some of these techniques and their performance tradeoffs.
