Reuptake modulator         
Transporter modulator; Transporter ligand; Uptake modulator
A reuptake modulator, or transporter modulator, is a type of drug which modulates the reuptake of one or more neurotransmitters via their respective neurotransmitter transporters. Examples of reuptake modulators include reuptake inhibitors (transporter blockers) and reuptake enhancers.
Photomechanical         
Photomechanical Effect; Photomechanical
·adj Pertaining to, or designating, any photographic process in which a printing surface is obtained without the intervention of hand engraving.
Photomechanical effect         
Photomechanical Effect; Photomechanical
Photomechanical effect is the change in the shape of a material when it is exposed to light. This effect was first documented by Alexander Graham Bell in 1880.
Sphingosine-1-phosphate receptor modulator

DRUG CLASS
User:Anhahe/sandbox/Sphingosine-1-phosphate receptor modulator; Draft:Sphingosine-1-phosphate receptor modulator
Sphingosine-1-phosphate receptor modulators are a class of drugs used as immunomodulators, most notably in cases of multiple sclerosis.
Opioid modulator         
DRUG
Opioid receptor modulator
An opioid modulator (or opioid receptor modulator) is a drug which has mixed agonist and antagonist actions at different opioid receptors and thus cannot clearly be described as either an opioid agonist or antagonist. An example of an opioid modulator is buprenorphine, which is a partial agonist of the μ-opioid receptor and an antagonist of the κ-opioid receptor.
Allosteric modulator         
  • CX614, a PAM for an AMPA receptor binding to an allosteric site and stabilizing the closed conformation
  • Orthosteric agonist (A) binds to orthosteric site (B) of a receptor (E). Allosteric modulator (C) binds to allosteric site (D). Modulator increases/lowers the affinity (1) and/or efficacy (2) of an agonist. Modulator may also act as an agonist and yield an agonistic effect (3). Modulated orthosteric agonist affects the receptor (4). Receptor response (F) follows.
SUBSTANCE THAT BINDS TO A REGULATORY SITE DISTINCT FROM THE ACTIVE SITE ON A PROTEIN, RESULTING IN CONFORMATIONAL CHANGES THAT MAY INFLUENCE PROTEIN FUNCTION
Allosteric modulation; Positive allosteric modulator; Negative allosteric modulator; Negative allosteric modulation; Positive allosteric modulation; Positive allosteric modulators; Negative allosteric modulators; Positive modulator; Positive modulators; Negative modulator; Negative modulators
In pharmacology and biochemistry, allosteric modulators are a group of substances that bind to a receptor to change that receptor's response to stimulus. Some of them, like benzodiazepines, are drugs.
Channel modulator         
TYPE OF DRUG WHICH MODULATES ION CHANNELS
Channelergic; Ion channel modulator
A channel modulator, or ion channel modulator, is a type of drug which modulates ion channels. They include channel blockers and channel openers.
Motorcycle headlamp modulator         
ACCESSORY DEVICE FOR MOTORCYCLES
Motorcycle Headlight Modulators; Motorcycle Headlight Modulator; Motorcycle Headlamp Modulator
A motorcycle headlamp modulator (or simply headlamp modulator) is an accessory device that oscillates the intensity of a motorcycle headlamp at 240 ±40 cycles per minute (~4 Hz)FMVSS 108 S7.9.
Acousto-optic modulator         
  • An acousto-optic modulator consists of a [[piezoelectric transducer]] which creates sound waves in a material like glass or quartz.  A light beam is diffracted into several orders.  By vibrating the material  with a pure sinusoid and tilting the AOM so the light is reflected from the flat sound waves into the first diffraction order, up to 90% deflection efficiency can be achieved.
  • Bragg Condition]] for an AOD. Λ is the wavelength of the sound wave, λ is that of the light wave, and n is the [[refractive index]] of the crystal in the AOD. The +1 order has a positive frequency shift compared to the incident light; The 0th order has the same frequency as the incident light. The minor transverse displacement of 0th order from the incident light represents the [[refraction]] inside the crystal.
USES THE ACOUSTO-OPTIC EFFECT TO DIFFRACT AND SHIFT THE FREQUENCY OF LIGHT USING SOUND WAVES
Acousto-optic modulators; Acoustooptic modulators; Bragg Cell; Electro-acoustic modulator; Electroacoustic modulator; Opto-acoustic modulator
An acousto-optic modulator (AOM), also called a Bragg cell or an acousto-optic deflector (AOD), uses the acousto-optic effect to diffract and shift the frequency of light using sound waves (usually at radio-frequency). They are used in lasers for Q-switching, telecommunications for signal modulation, and in spectroscopy for frequency control.
Spatial light modulator         
  • Schematic of a liquid crystal-based Spatial Light Modulator. As liquid crystals are birefringent, applying a voltage to the cell changes the effective refractive index seen by the incident wave, and thus the phase retardation of the reflected wave.
USED IN OPTICAL PROJECTION
Spatial light modulators; Light modulator
A spatial light modulator (SLM) is an object that imposes some form of spatially varying modulation on a beam of light. A simple example is an overhead projector transparency.

Analog multiplier

In electronics, an analog multiplier is a device that takes two analog signals and produces an output which is their product. Such circuits can be used to implement related functions such as squares (apply same signal to both inputs), and square roots.

An electronic analog multiplier can be called by several names, depending on the function it is used to serve (see analog multiplier applications).
