    On Wednesday, the 13th of March 1991, American Cablevision of Queens, New York, sent the first electronic "Bullet". This so-called "Bullet" was in fact, an electronic signal directed to unauthorized cable boxes causing them to turn-off. Approximately 300+ unsuspecting customers then called the cable company to complain and were subsequently taken to court for cable theft. The "Bullet" works by ordering the computer processor within the cable box to lock-up if it is authorized for all channels. Since

  • FM Receivers

    receiver to boost signal power at radio, baseband and intermediate frequencies. The core of the FM receiver, the discriminator, comes in various circuit forms and is used in detection and demodulation. Basically, its role is to extract the intelligence or message from the carrier wave. Another component, essential in most electronic circuits, is the power supply (DC or AC converted to DC). Finally, a transducer (speaker in the case of Radio) is needed to convert the message signal into its final form

  • Vision and Blindsight

    1629 Words  | 4 Pages

    interpreting light signals from the environment in order to form an image in one's mind-- is an incredibly complex process. Somehow signals from photoreceptors located in the eye are converted into the conscious experience of sight. Of all the aspects of vision, perhaps the most difficult for us to comprehend scientifically is this notion of consciousness. Somehow the brain interprets light waves hitting the retina so that we are visually aware of our surroundings. While the mechanism of signal transduction

  • Importance of Memory Color

    see traffic signals or enjoy sunsets, and learning techniques would be much more difficult. Color is an important function that signals and helps facilitate perceptual organization. Memory color is a phenomenon in which an object's characteristic color influences our perception of its color. The study of what colors will maximize memorization skills is important for many reasons. Human beings rely on color to keep order in our lives. Traffic signals, warning signs, and many other signals require perception

    can generate reliable power for the rest of the computer, and having it turn on prematurely could potentially lead to damage. Therefore, the chipset will generate a reset signal to the processor (the same as if you held the reset button down for a while on your case) until it receives the Power Good signal from the power supply. 2. When the reset button is released, the processor will be ready to start executing. When the processor first starts up, it is suffering from amnesia; there is nothing at

    depolarize with only slight perturbations of the inner ear fluid. At the point of depolarization, a neural signal is transmitted and on its way to the brain. This nerve impulse travels to the auditory nerve (8th cranial nerve), passes through the brainstem, and then reaches the branched path of the cochlear nucleus: the ventral cochlear nucleus or the dorsal cochlear nucleus. The nerve signal that passes through the ventral cochlear nucleus will reach the superior olive in the medulla where differences

  • Bradykinesia

    are ineffective in this person, whereas a person with bradykinesia can only react completely and at a normal speed to external stimuli. Because of damage to signal pathways, the internal stimuli are ineffectively activated. (1) Bradykinesia is a Greek term that means "slow movement", and it is one of the constituents of Parkinson's disease (2), although it is also associated with other diseases. For patients suffering from Parkinson's disease, it is usually the most tiring and frustrating of the

    properly terminated (which kills the signal) then we can receive what's called bounce back. This ricocheting of the data could severely hinder the communication pathing of the bus. As I recall there is a general rule of thumb for a bus topology which is the rule of 5-4-3-2-1. This means that you can have 5 data segments of which there can be 4 connectors (continuing connections) which link the 5 data segments. 3 of the segments must be populated. There must be 2 terminators on the bus (1 at each

    users as possible in a given band. GSM uses a combination of two distinct methods to achieve these tight requirements. Digitalisation GSM is a digital system. Let's take a closer look at what it means, if a signal is analogue or digital. An analogue signal means in principle, that the signal can have any values at any time. A good example is a traditional thermometer outside your window. The range of the meter is typically from -40 Celsius to +40 Celsius and the reading can be anything between

  • Incomplete and Complete Achromatopsia

    is an X-linked recessive disorder in which only the blue cones and the rods are functioning properly. A previously proposed theory states that signals from rods travel in the same pathways which carry signals from the blue-cones, making color vision in a blue-cone monochromat impossible. However, current research on blue-cone monochromats shows that signals from some rods and cones may be traveling by separate pathways to where wavelength discrimination takes place, making color vision possible in

  • Organisation culture

    conceptualised culture as a ‘process of enactment’ – not as something that exists ‘out there’ separate from people, but which was actually manufactured by company employees as they interacted with one another on a daily basis within the workplace.2 In highlighting the symbolic significance of virtually every aspect of organisation life, the culture metaphor thus focuses attention on a human side of organisation that other metaphors ignore or gloss over. The culture metaphor opens the way to

  • Traffic Signal/Road Marking Detection and Processing

    1871 Words  | 4 Pages

    Traffic Signal/Road Marking Detection and Processing Humans have visual cues that they naturally use to perceive their motion through the environment. There are numerous human factors that are associated with being able to navigate a vehicle safely while adhering to signal lights, signs and other traffic road markings. There needs to be vast improvement in the way that information is presented to drivers for many reasons. One example is that the placing of the sun during a particular part of

    maintain the balance required to keep the tower intact while in the dark (1). What does darkness have to do with it? The point is that balance relies on at least three signals coming from the body, and one of those is sight. Once you eliminate one of these signals, the body cannot accomplish the required task. In addition to sight, signals coming from muscles and joints, called proprioceptors are sensitive to changes in position. The third contributor to the human tower and the topic of discussion of
