High Quality Content by WIKIPEDIA articles! A Passive InfraRed sensor (PIR sensor) is an electronic device that measures infrared (IR) light radiating from objects in its field of view. PIR sensors are often used in the construction of PIR-based motion detectors (see below). Apparent motion is detected when an infrared source with one temperature, such as a human, passes in front of an infrared source with another temperature, such as a wall.All objects emit what is known as black body radiation.

High Quality Content by WIKIPEDIA articles! Passive radar systems (also referred to as passive coherent location and passive covert radar) encompass a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals. It is a specific case of bistatic radar, the latter also including the exploitation of cooperative and non-cooperative radar transmitters.Conventional radar systems comprise a collocated transmitter and receiver, which usually share a common antenna to transmit and receive. A pulsed signal is transmitted and the time taken for the pulse to travel to the object and back allows the range of the...

High Quality Content by WIKIPEDIA articles! A passive radiator or parasitic element is a radio antenna element which does not have any wired input. Instead, it absorbs radio waves radiated from a nearby active antenna element, and re-radiates it. To the extent the current in the parasitic element leads or lags that of the active element the parasitic element can reflect or direct the signal. This changes the antenna pattern and beam width.Parasitic elements can also be used to alter the radiation parameters of nearby active elements. An example of this is to place a parasitic microstrip patch antenna above another driven patch antenna. This antenna combination resonates at a slightly lower frequency than the original element. However,...

High Quality Content by WIKIPEDIA articles! A passive differentiator circuit is a simple four-terminal network consisting of two passive elements as shown in Figures 1 and 2. It is a simple first-order high-pass filter.The analysis here is for the capacitive circuit in Figure 1. The inductive case in Figure 2 can be handled in a similar way.The transfer function shows the dependence of the network gain on the signal frequency for sinusoidal signals.

High Quality Content by WIKIPEDIA articles! A passive attack on a cryptosystem is one in which the cryptanalyst cannot interact with any of the parties involved, attempting to break the system solely based upon observed data (ciphertext). This can also include known plaintext attacks where both the plaintext and its corresponding ciphertext are known. While most classical ciphers are vulnerable to this form of attack, most modern ciphers are designed to prevent this type of attack above all others. Данное издание не является оригинальным.

High Quality Content by WIKIPEDIA articles! A passphrase is a sequence of words or other text used to control access to a computer system, program or data. A passphrase is similar to a password in usage, but is generally longer for added security. Passphrases are often used to control both access to, and operation of, cryptographic programs and systems. Passphrases are particularly applicable to systems that use the passphrase as an encryption key. The origin of the term is by analogy with "password". The modern concept of passphrases is believed to have been invented by Sigmund N. Porter in 1982. Данное издание не является оригинальным. Книга печатается по технологии...

High Quality Content by WIKIPEDIA articles! In cryptography, a password-authenticated key agreement method is an interactive method for two or more parties to establish cryptographic keys based on one or more party's knowledge of a password. Password authenticated key exchange (PAKE) is where two or more parties, based only on their knowledge of a password, establish a cryptographic key using an exchange of messages, such that an unauthorized party (one who controls the communication channel but does not possess the password) cannot participate in the method and is constrained as much as possible from guessing the password. (The optimal case yields exactly one guess per run exchange.) Two forms of PAKE are Balanced and Augmented methods....

Password fatigue, also known as password chaos or identity chaos, is the feeling experienced by many people who are required to remember an excessive number of passwords as part of their daily routine, such as to logon to a computer at work, undo a bicycle lock or conduct banking from an ATM.The increasing prominence of information technology and the Internet in employment, finance, recreation and other aspects of people's lives, and the ensuing introduction of secure transaction technology, has led to people accumulating a proliferation of accounts and passwords. According to a 2002 survey of British online-security consultant NTA Monitor, the typical intensive computer user has 21 accounts...

High Quality Content by WIKIPEDIA articles! A password is a secret word or string of characters that is used for authentication, to prove identity or gain access to a resource (example: an access code is a type of password). The password must be kept secret from those not allowed access. The use of passwords is known to be ancient. Sentries would challenge those wishing to enter an area or approaching it to supply a password or watchword. Sentries would only allow a person or group to pass if they knew the password. In modern times, user names and passwords are commonly used by people during a log in process that controls access to protected computer operating systems, mobile phones, cable TV decoders, automated teller machines (ATMs),...

High Quality Content by WIKIPEDIA articles! Password cracking is the process of recovering passwords from data that has been stored in or transmitted by a computer system. A common approach is to repeatedly try guesses for the password. The purpose of password cracking might be to help a user recover a forgotten password (though installing an entirely new password is less of a security risk, but involves system administration privileges), to gain unauthorized access to a system, or as a preventive measure by system administrators to check for easily crackable passwords. On a file-by file basis, password cracking is utilized to gain access to digital evidence for which a judge has allowed access but the particular file's access is...

A pastry bag (or piping bag in the Commonwealth) is an often cone- or triangular-shaped, hand-held bag made from cloth, paper, or plastic that is used to pipe semi-solid foods by pressing them through a narrow opening at one end, for many purposes including cake decoration. It is filled through a wider opening at the opposite end, rolled or twisted closed, and then squeezed to extrude its contents.Though a circular nozzle is quite useful for making round shapes and for filling pastries such as profiteroles, many differently-shaped nozzles are commonly used to produce star, leaf, and flower-petal shapes.

High Quality Content by WIKIPEDIA articles! Pastry is an overlay and routing network for the implementation of a distributed hash table similar to Chord. The key-value pairs are stored in a redundant peer-to-peer network of connected Internet hosts. The protocol is bootstrapped by supplying it with the IP address of a peer already in the network and from then on the routing table is dynamically built and repaired. Because of its redundant and decentralized nature there is no single point of failure and any single node can leave the network at any time without warning and with little or no chance of data loss. The protocol is also capable of using a routing metric supplied by an outside program, such as ping or traceroute, to determine...

High Quality Content by WIKIPEDIA articles! A patch antenna (also known as a Rectangular Microstrip Antenna) is a popular antenna type. Its name is attributed to the fact that it consists of a single metal patch suspended over a ground plane. The assembly is usually contained inside a plastic radome, which protects the antenna structure from damage (as well as concealing its essential simplicity). Patch antennas are simple to fabricate and easy to modify and customize. They are the original microstrip antenna as described by Howell , which are a length of microstrip transmission line of approximately one-half wavelength. The radiation mechanism arises from discontinuities at each truncated edge of the microstrip transmission line....
