Notes, summaries, assignments, exams, and problems for Electronics

Detailed engineering is the phase in which information is taken from the basic engineering and developed to a sufficient degree to allow the construction of the project. The goal is to develop detailed information and documentation.

Activities

• Define the different areas that will form the subject of the project installation.
• Define the means of production, creating a list of machines, equipment control, and automation equipment involved in the system.
• Definition of networks and supporting facilities.
• Organization for the means of production, defining for each workstation which machines and items are controlled and monitored.
• Organization of production cycles so that there is an adequate flow between each machine and workstation, minimizing downtime.

Multi-Circuit: Intermittent Power Supply

This electronic circuit provides intermittent power and can be supplemented with a device that detects malfunctions by placing two additional transistors.

Veri.Mani: Pilot Testing and Reverse Voltage

Pilot testing began with a system that does not function in reverse voltage to current.

Fuel Level Sensors: Analog and Digital Indicators

Fuel level sensors are responsible for displaying the amount of liquid in a deposit. These can be analog or digital and are based on the principle of a float or rheostat.

Oil Pressure Monitoring: Lamp and Monocontacto

Oil pressure is usually controlled by a lamp. If the oil level is low, the unit responsible for lighting the lamp is called a monocontacto. When cranking or starting... Continue reading "Automotive Electronic Systems: Functionality and Operation" »

Literacy Development: Essential Skills

It's the ability to read and write to understand communication, but it also includes the critical and effective use of language for all purposes. The five steps in literacy development are:

1. Phonemic Awareness: The recognition of a sequence of individual sounds in a word.
2. Decoding: What a person uses to interpret a printed sentence; the ability to associate sounds with letters and use them to form words.
3. Fluency: Reading fluency indicates that a child can read successfully. Successful reading is reading with accuracy and automatically, with proper speed and intonation. Children will not be able to comprehend text if they do not become fluent readers.
4. Comprehension: Requires the reader to be an active constructor

Internet Radio: Concept

Internet radio is not radio in the traditional sense; it is more than that. The sound image is contextualized with written information in addition to the strict emission of conventional programming offered by each of the radio stations on medium wave and FM. On the Internet, we discover two types of sonic performance:

• Radio in the strict sense, as we know it, with continuous broadcasts and structured programming subject to a temporary schedule.
• A series of written information on various content, supported by images and enriched sound material.

For all of us, talking about the newspaper, radio, or TV on the Internet is not only easier but more comfortable.

According to Cebrián Herreros, the preliminary step before embarking... Continue reading "Internet Radio: Concept and Consumption Habits" »

Understanding Journalistic Texts

Journalistic texts, aimed at informing about current events and topics of general interest, are included in the so-called mass media. However, informing is not their sole purpose, as they also incorporate reviews, opinions, or criticisms about certain behaviors, events, and attitudes.

These texts possess very heterogeneous characteristics, offering information on national, international, local, sports, cultural, educational, and economic topics. They are fundamentally divided into sections, accommodating the expression of opinion.

Both the sender (the media outlet, though the text is written by a journalist) and the receiver (the audience) are collective entities. The relationship between sender and receiver is... Continue reading "Journalistic Communication: Functions, Language, and Characteristics" »
