When visible GPS satellites are close together in the sky, the geometry is said to be weak and the DOP value is high ; when far apart, the geometry is strong and the DOP value is low.

When attached to a GPS receiver, even this requirement is removed, as the scanner will automatically determine it position and continuously update the systems as the user relocates.

When first turned on in these conditions, some standalone GPS navigation devices may not be able to fix a position due to the fragmentary signal, rendering them unable to function until a clearer signal can be received continuously for a long enough period of time.

When automobiles first started shipping with on-board GPS systems, it was not uncommon to use a forcing function which prevented the user from interacting with the GPS ( such as entering in a destination ) while the car was in motion.

The monochrome combinations still existing in the 1950s are standardized by the International Telecommunication Union ( ITU ) as capital letters A through N. When color television was introduced, the hue and saturation information was added to the monochrome signals in a way that black & white televisions ignore.

When analog television was developed, no affordable technology for storing any video signals existed ; the luminance signal has to be generated and transmitted at the same time at which it is displayed on the CRT.

Neurons generate electrical signals that travel along their axon s. When a pulse of electricity reaches a junction called a synapse, it causes a neurotransmitter chemical to be released, which binds to receptors on other cells and thereby alters their electrical activity.

When the myelin sheath is damaged, nerve signals are slower, and this can be measured by a common neurological test, electromyography.

When two stations transmit at the same phase-locked frequency, the difference in phase between the two signals is constant along a hyperbolic path.

When the actuator reaches the desired position, the two signals ( incoming and outgoing ) cancel each other out and the actuator stops moving ( completing a feedback loop ).

When processing signals, such as audio, radio waves, light waves, seismic waves, and even images, Fourier analysis can isolate individual components of a compound waveform, concentrating them for easier detection and / or removal.

When myelin degrades, conduction of signals along the nerve can be impaired or lost and the nerve eventually withers.

When the row was activated, it would activate the control signals connected to it.

When GPIO pins are configured to an input state, they are often used to read sensors or external signals.

When myelin degrades, conduction of signals along the nerve can be impaired or lost, and the nerve eventually withers.

When nociceptors are stimulated they transmit signals through sensory neurons in the spinal cord.

When the water level is below both switches, the switch contacts are closed providing signals to both the " Low Level " and " High Level " inputs to the PLC.

When the bladder is stretched, this signals the parasympathetic nervous system to contract the detrusor muscle.

When not actively in contact with another station, the HF SSB transceiver constantly scans through a list of HF frequencies called channels, listening for any ALE signals transmitted by other radio stations.

When both signals are nearly equal in strength, or are fading independently, the receiver may switch from one to the other and exhibit picket fencing.

When the voltages are nearly equal, the output voltage will not fall into one of the logic levels, thus analog signals will enter the digital domain with unpredictable results.

When the two signals are mixed, a " beat " frequency equal to the difference between the two frequencies is created.

When loading coils are in place, signal attenuation remains low for signals within the passband of the transmission line but increases rapidly for frequencies above the audio cutoff frequency.

When voice signals are digitized for transmission via T-carrier, the data stream always includes ample 1 bits to maintain synchronization.

When large numbers of delayed signals are mixed over several seconds, the resulting sound has the effect of being presented in a large room, and it is more commonly called reverberation or reverb for short.

When some repair nerves are prodded by compression or pain to send out their repair signals, a chain reaction spreads out to set other repair nerves in the same meridian into action.

When I show up he will know you are a good wife to have told him about it ''.

When the Know-nothings get control, it will read, All men are created equal except Negroes and foreigners and Catholics.

When the reactionary response is thus bolstered by an intellectual defense, the characteristics of that defense are explicable only in terms of the basic attitudes of unanalyzed reaction.

When combined with the metaphysical notion that pure forms of this universe are best appreciated when least embodied in a material substratum, it becomes clear that while earth will be dross on a scale of material-formal ratios, celestial bodies will be of a subtle, quickened, ethereal existence, in whose embodiment pure form will be the dominant component and matter will be absent or remain subsidiary.

She used to tell me, `` When I stand there and look at the flag blowing this way and that way, I have the wonderful, safe feeling that Americans are protected no matter which way the wind blows ''.

When we consider the disorganized state of the world community, and the legacy of predispositions adversely directed against all who are identified as Jews, it is obvious that the struggle for the minds and muscles of men needs to be prosecuted with increasing vigor and skill.

When these fields are surveyed together, important patterns of relationship emerge indicating a vast community of reciprocal influence, a continuity of thought and expression including many traditions, primarily literary, religious, and philosophical, but frequently including contact with the fine arts and even, to some extent, with science.
