Awareness signal device

Awareness signal—A device that warns a person of an approaching or present hazard by means of audible sound or visible light. 

We have also studied the digital signal intensity versus light intensity behavior of the photodiode array detector used in method B. Non-linear effects have been observed for Vidicon multichannel analyzers when employed in measuring the intensity of picosecond duration light. Photodiode arrays, in contrast, have rarely been employed in picosecond spectrometer, and, we are not aware of a previous study of the linearity of these devices for the detection of high intensity picosecond duration light. 

The nerve cell, or neuron, is an unusual looking cell (Fig. 8-1). A neuron may be only 0.1 mm in diameter but, may reach lengths of a meter or more. The threadlike extension from the cell body is the nerve fiber. These fibers interconnect in various special areas of the body, including the brain, the spinal cord, and the peripheral nerves. The function of the neuron is to transmit signals, or impulses. The dendrites specialize in receiving excitations, which may be from environmental stimuli (i.e., from peripheral parts of the body, or from another cell). The axon conducts the excitation away from the dendrite area (e.g., to the brain).1 This excitation, or impulse transmission, may be on a subconscious level. Transmissions of which the subject is not consciously aware are the type that control various body functions such as temperature, respiration, blood pressure, and peristaltic movements of the gastrointestinal tract. In addition to the traditional functions of a cell membrane, the membrane of the nerve fiber (the axon) has the role of transmitting the electrochemical impulses that are received from the dendrites. The additional protective device called the myelin sheath basically serves as an electrical insulator. 

The QoS platform should be based on the layer independent from the techniques as well as network mechanisms applied in the administrative domains of video monitoring network. It should also deliver unified interfaces to individual network devices and applications. In order to fulfill these requirements, the QoS platform consist of QoS Streaming Server and Resource Broker modules and QoS-aware Client module with signaling and link capacity estimation functionalities, as it was already mentioned. Such platform is shown in Figure 1. 

The brain uses the neuromuscular channels to communicate and control its external environment, however many disorders can disrupt these channels. Amyotrophic lateral sclerosis is one such disorder which impairs the neural pathways and completely paralyses the patient. This disorder affects nearly ten million people around the world. Those most severely affected may lose all voluntary muscle control and may be completely locked-in to their bodies, unable to communicate in any way. These patients however have an active brain and are aware of their surroundings. One of the options for restoring function to these patients is to provide the brain with a system which can decode the brain signals and change them to proper messages for controlling an external device [1] [2].
