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 ...
The generalised chemical structure of polyisocyanurate showing the isocyanurate group. The polyols are abbreviated as R-groups.. Polyisocyanurate (/ ˌ p ɒ l ɪ ˌ aɪ s oʊ s aɪ ˈ æ nj ʊər eɪ t /), also referred to as PIR, polyol, or ISO, is a thermoset plastic [1] typically produced as a foam and used as rigid thermal insulation.
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.
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.
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 ...
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.
Committed data rate (CDR) is the payload portion of the CIR. [1] At any given time, the available bandwidth should not fall below this committed figure. The bandwidth is usually expressed in kilobits per second (kbit/s). Above the CIR, an allowance of burstable bandwidth is often given, whose value can be expressed in terms of an additional ...
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 ...
