  2. Passive infrared sensor - Wikipedia

    en.wikipedia.org/wiki/Passive_infrared_sensor

    A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give ...

  3. Polyisocyanurate - Wikipedia

    en.wikipedia.org/wiki/Polyisocyanurate

    PIR board fire test. PIR is at times stated to be fire retardant, or contain fire retardants, but these describe the results of "small scale tests" and "do not reflect [all] hazards under real fire conditions"; [9] [better source needed] the extent of hazards from fire include not just resistance to fire but the scope for toxic byproducts from ...

  4. Electrical safety testing - Wikipedia

    en.wikipedia.org/wiki/Electrical_safety_testing

    An insulation resistance test (IR test) measures the electrical resistance of insulation by applying a voltage between two locations, and measuring the resultant current flow. Proper safety precautions must be taken when doing this test, such as exclusion zones, making sure no wires are exposed, and personal protective equipment is worn.

  5. Revised NEO Personality Inventory - Wikipedia

    en.wikipedia.org/wiki/Revised_NEO_Personality...

    The Revised NEO Personality Inventory (NEO PI-R) is a personality inventory that assesses an individual on five dimensions of personality. These are the same dimensions found in the Big Five personality traits. These traits are openness to experience, conscientiousness, extraversion (-introversion), agreeableness, and neuroticism.

  6. Florbetapir (18F) - Wikipedia

    en.wikipedia.org/wiki/Florbetapir_(18F)

    Florbetapir (18F), sold under the brand name Amyvid, is a PET scanning radiopharmaceutical compound containing the radionuclide fluorine-18 that was approved for use in the United States in 2012, [4] as a diagnostic tool for Alzheimer's disease. [5][6][7][8] Florbetapir, like Pittsburgh compound B (PiB), binds to beta-amyloid, however fluorine ...

  7. Occupancy sensor - Wikipedia

    en.wikipedia.org/wiki/Occupancy_sensor

    Occupancy sensor types include: PIR sensors, which work on heat difference detection, measuring infrared radiation.Inside the device is a pyroelectric sensor which can detect the sudden presence of objects (such as humans) who radiate a temperature different from the temperature of the background, such as the room temperature of a wall.

  8. Private information retrieval - Wikipedia

    en.wikipedia.org/wiki/Private_information_retrieval

    Private information retrieval. In cryptography, a private information retrieval (PIR) protocol is a protocol that allows a user to retrieve an item from a server in possession of a database without revealing which item is retrieved. PIR is a weaker version of 1-out-of- n oblivious transfer, where it is also required that the user should not get ...

  9. Peak information rate - Wikipedia

    en.wikipedia.org/wiki/Peak_information_rate

    Peak information rate ( PIR) is a burstable rate set on routers and/or switches that allows throughput overhead. Related to committed information rate (CIR) which is a committed rate speed guaranteed/capped. For example, a CIR of 10 Mbit/s PIR of 12 Mbit/s allows you access to 10 Mbit/s minimum speed with burst/spike control that allows a ...
