Classes, control and saving Essay Example for Free

Classes, control and saving Essay This section is a grouping of elements influencing various forms of power control. The specification highlights three device power classes possible for Bluetooth radios that are related to the power range of the transmitter: †¢ Class 1 is 100mW and up to about 100m range †¢ Class 2 is 2. 5mW and up to about 20m range †¢ Class 3 is 1mW and up to about 10m range Radios are subject to environmental influences and the Class 3 range of up to 10 meters is more likely to be 5 meters when furniture or people are in proximity of the radio. This form of power control is provided to cut down on interference with other devices in the ISM band and obviously help prolong battery life (see â€Å"Bluetooth: Goodbye Infrared†). The second form of power control is on the receiver side of a Bluetooth device. To enable all classes to communicate in a Piconet without damage to the RF front ends of the lower power classes, a method for controlling Class 1 device transmitter power is required. Transmit power control is mandatory above 4 dBm, below this level i. e. all Class 2 and 3 modules it is optional. To implement a power control link the remote device must implement a Receive Signal Strength Indicator (RSSI). For a transceiver wishing to take part in a power controlled link it must be able to measure its own receiver signal strength and determine if the transmitter on the other side of the link should increase or decrease its output power level. The RSSI makes this possible. Power control is specified is as a golden receive power, defined as a range with a low limit and a high limit. The RSSI must have a minimum dynamic range equal to this range. The RSSI must have an absolute accuracy of  ±4dB or better when the receiver signal power is –60 dBm. In addition, a minimum range of 20. 6 dB must be covered, starting from –60 dB and up. The instructions to alter the transmitter power are carried in the Link Manager Protocol (LMP) link (see â€Å"Bluetooth: Goodbye Infrared†). The last form of power control relates to the power consumption. The Hold, Sniff and Park modes are power saving modes set out in the specification aiming to preserve battery consumption. The Hold mode is typically used when a master is establishing a link with a new device and requires the other slaves to temporarily halt their transmissions. The Sniff mode puts slaves into a low duty cycle mode of operation but is still an active member of the Piconet and the master can only transmit after a ‘sniff’ interval. In Park mode slaves enters a low duty cycle mode of operation and are no longer active members of the Piconet (see â€Å"Bluetooth: Goodbye Infrared†). B. Applications and Profiles. Undeniably the ideal candidate for the first wave of applications will inevitably be based on mobile cellular technology, but what other applications can be realised using Bluetooth technology? The specifications outline a wireless technology that is as cost effective as the cable it replaces and aim to balance reliability, resilience, convenience and low power. The short-range connections of data and voice could mean the emergence of applications suitable for: ? Access points allowing mobile devices connection to services e.g. telephone network (PSTN) or LAN services. ? Mobile phone link to Laptop PCs ? Mobile phone connections to wireless headsets ? PDA, palmtop and desktop PC inter accessibility for file and data synchronisation. The Bluetooth core specification describes the protocol, but the Profiles document enhances this by setting out a number of profiles for applications and defining the way a number of services operate e. g. a file transfer profile defines how devices exchange data files. The profile document aids applications development, describing implementation schemes and highlights parts of the core Bluetooth protocol supporting the profile. Profiles supported are outlined in Figure 6; they are depicted grouped together. Each profile is built upon the one underneath, attaining their features from the lower profiles. The result of this approach gives the profiles a similar look and feel for user recognition. Plus developers can recycle modules for speeding up development time and reducing costs (see â€Å"Bluetooth Technology: What are the Applications? †). A wireless headset for a mobile phone is an application example using the profiles. It uses the Headset profile as its core specification. In Figure 6 the Headset profile is built from the Serial Port Profile (SPP) and the Generic Access Profile (GAP). The GAP being the base of all profiles, it defines the generic procedures related to device discovery and link management (see â€Å"Bluetooth Technology: What are the Applications? †). Figure 6: Bluetooth Profiles.

Respect for Persons,Beneficence, and Justice :: Research Researching Privacy Essays

Respect for Persons,Beneficence, and Justice In July of 1974 The National Research Act was signed into law. Through this act, The Belmont Report was developed over 4 year period of time that included an intense four day conference followed by monthly meetings until it was completed in April of 1979. The Belmont Report sets out to define the ethical principles and guidelines for the protection of human subjects of research. The report was established prior to Barney Clark and the artificial heart and therefore was the guidelines that the doctors and researchers had to follow. The report highlights three essential ethical elements that are pertinent in human research and their applications. It was the professional responsibility of the doctors and researchers involved to abide by previously established ethical guidelines. Respect for Persons Respect for the Persons as it relates to the Barney Clark case can be broken down into three important issues. Autonomy The doctors made the assumption that Barney Clark was a fully autonomous person at the time of the artificial heart experiment. In general it is not in doubt that Mr. Clark was an autonomous being, however his terminal condition could have affected his capacity with in the case. While he might have been autonomous in many areas of his life the issue that is relevant to the case was whether he possessed the capacity to make an informed consent. Informed Consent The nine basic rules4 for an informed consent are 1. Identifying the appropriate decision maker 2. Having the discussion at a time when the patient is not distracted or in great pain. 3. Determine that the patient is communicating voluntarily 4. Disclose a. Nature of the proposed intervention b. The purpose c. The risks and consequences d. The benefits e. The probability that the intervention would be successful f. The feasible alternatives g. The prognosis is the intervention/therapy is not given 5. Offer a recommendation 6.

Assginment

The first individual believe that the root cause of committing a crime is poverty. When a individual has no money and he cannot provide the essential needs for himself or his family (food, clothes, shelter, etc†¦ ) he loses his sense to distinguish between right and wrong which leads to crime (robbery, murder, breaking laws, etc†¦ ). As income levels rise, crime levels often decline proportionately. People living in poverty commit crimes because, for them, the benefits of stealing something outweigh the risk of getting aught. Also, poor people have high rates of illiteracy and high levels of poverty.A lack of education leaves few opportunities for well-paying Jobs, which increases the likelihood that an individual might succumb to poverty and commit crimes. The effects multiply since one person in a neighborhood who commits a crime sends a message to others in the neighborhood that criminal behavior is acceptable. According to this individual collective society should be pu nished, not the individual who committed the crime. Collective society is the real culprit because they tolerate unjust societies that allows poverty. Behaviorism theory best describes this explanation.The second individual believe that the root cause of committing a crime is poor parenting, specifically, the failure of some parents to teach their children the values of respect for the law and for the rights of others. Children who are neglected or abused are more likely to commit crimes later in life than others. Similarly, sexual abuse in childhood often leads these victims to become sexual predators as adults. This individual also thinks that single-parent families are not only more likely to live n poverty, but they also are more likely to commit crime.Children who grow up in adults. According to this individual councils should make greater use of their powers to force violent parents to attend counseling or face court. Psychoanalysis theory best describes this explanation. The third individual believes that the root cause of committing a crime is drug and alcohol abuse. The urge to commit crime to support a drug habit definitely influences the decision process. Both drugs and alcohol impair Judgment and reduce inhibitions, giving a person greater courage to commit a crime. Drugs are related to crime in multiple ways.Most directly, it is a crime to use, possess, manufacture, or distribute drugs classified as having a potential for abuse (such as cocaine, heroin, marijuana, and amphetamines). Drugs are also related to crime through the effects they have on the user's behavior and by generating violence and other illegal activity in connection with drug trafficking. This invalid also believes that alcohol consumption alters three fundamental factors relating to motor vehicle crashes. It decreases driver performance, increases risk-taking behavior and decreases the hence of survival of occupants involved in crashes.According to this individual it is hypocrisy for society to permit alcohol but prohibit heroin as both drugs are dangerous. Alcohol is a greater factor in violent crime than any other drug while nicotine results in many deaths. Drug supply can only be reduced by reducing demand, and demand is caused by poor nutrition and a lack of education and wisdom in matters pertaining to health. The re-deduction of all children in basic dietary needs of the human body is a primary solution to drug addiction. Prisons would not be used as places of punishment, but rehabilitation.The health approach is fare wiser and humane than the severe authoritarian imposition of punishment. Generally we need a more tolerant,informed, educated and less Judgmental approach to drug crime. Punishment usually fails to reform. Treatment of causal factors can accomplish much more. Biological approach theory best describes this explanation. Question 3. ) Pick one of your traits, and explain the influences that both nature and nurture have on it. For example, i f you have a short temper, explain its origins in your emetics, your culture and your childhood experiences.One of my major traits is caring. Caring is hereditary in my family. My mom and grandfather are caring. My grandfather was a landlord in Pakistan and he use to do allot for people who were poor, like giving them a free land and telling them not to worry about anything. My mom use to help every one of her relatives and friends in their time of need. I am a caring person since I was born, during my childhood, I use to care allot for my family including my parents, grandparents, siblings, and my friends by doing little things for them.For example, my sister and I use to share a bed and blanket, and in the middle of the night, she would take the whole blanket to herself in her sleep and I would let her sleep with the blanket while I sleep without it. So, caring is in my nature, it's how I am. My personality of caring nurtured while growing up. I went a level up in caring and made caring my profession by becoming a nurse (LIP). Now not only care for my family and friends I also care for my patients. I am proud to care for people who are in need of medical help and I am glad to help hem.I also have three children now and I show them that I care for them by homecomings all three of them. I work four to five days a week, twelve hours per day, Just for them, so that they can have a good childhood and life ahead. Question 4. ) People sometimes wonder how any pregnant woman could Jeopardize the health of her fetus. Consider your own health-related behavior in the past month†¦ Exercise, sleep, nutrition, drug use, medical and dental care, disease avoidance and so on. Would you change your behavior if you were pregnant?Would t make a difference if your family, your partner, or you yourself did not want a baby? Whole lifestyle. I would eat healthy, do exercises that are good and healthy for me and the baby, sleep on time and if I was taking any unhealthy drugs I would stop, basically I would not Jeopardize the baby's life under any circumstances. If I had any bad habits like smoking or drinking alcohol I would try my best to leave all my bad habits and take care of the baby. No, it would not make a difference if my family, my partner, or l, myself did not want a baby. I would still care for it and take care of it.

The Legend And The Sky - 2818 Words

Osiris and the Sky; The Legend and the Stars Since the beginning of time, people have looked to the sky for wisdom, guidance, and understanding. The stars have been a source of excitement for billions of years. Mankind has always looked to the stars to understand our world. They have given us a sense of belonging and purpose. Something so remarkable about man’s relationship with the stars are the myths we’ve made to go along with them. To this day, these myths are still used by astronomers to identify stars and constellations and to better understand our skies. It is within these myths that we come face to face with our ancestors and the way they viewed the sky. The Ancient Egyptians were one of the most intelligent and advanced cultures to ever live. Whether it be in engineering, science, language, economics, government, or astronomy, the Ancient Egyptians made huge strides and dominated the ancient world. Astronomy is just one of the many areas the Ancient Egyptians s eemed to masterly understand. They made discoveries that were far advanced for their times. Mythology was how they understood these discoveries and their myths are still used to this day. One myth that holds significant importance to the Ancient Egyptians and their culture, and most importantly, astronomy, is the Legend of Osiris.
