    en.wikipedia.org/wiki/List_of_awareness_ribbons

    This is a partial list of awareness ribbons. The meaning behind an awareness ribbon depends on its colors and pattern. Since many advocacy groups have adopted ribbons as symbols of support or awareness, ribbons, particularly those of a single color, some colors may refer to more than one cause.

  3. Track while scan - Wikipedia

    en.wikipedia.org/wiki/Track_while_scan

    Track-while-scan ( TWS) is a mode of radar operation in which the radar allocates part of its power to tracking a target or targets (up to forty with modern radar) while part of its power is allocated to scanning. It is similar to but functions differently in comparison to its counterparts range-while-search (RWS), long range search (LRS), air ...

  4. Kerr-lens modelocking - Wikipedia

    en.wikipedia.org/wiki/Kerr-lens_modelocking

    Kerr-lens modelocking. Kerr-lens mode-locking ( KLM) is a method of mode-locking lasers via the nonlinear optical Kerr effect. This method allows the generation of pulses of light with a duration as short as a few femtoseconds . The optical Kerr effect is a process which results from the nonlinear response of an optical medium to the electric ...

  5. Depletion and enhancement modes - Wikipedia

    en.wikipedia.org/.../Depletion_and_enhancement_modes

    Voltages that lead to channel formation are not shown. In field-effect transistors (FETs), depletion mode and enhancement mode are two major transistor types, corresponding to whether the transistor is in an on state or an off state at zero gate–source voltage. Enhancement-mode MOSFETs (metal–oxide–semiconductor FETs) are the common ...

    A Mode 5 warning in EGPWS alerts the pilots if they descend below the glideslope during a landing approach. Evolution to EGPWS & TAWS. After these rules were issued, advances in terrain mapping technology permitted the development of a new type of ground proximity warning system that provides greater situational awareness for flight crews.

The KLJ-7, also referred to as the Type 1478, is an X band airborne fire-control radar (FCR) developed by Nanjing Research Institute of Electronic Technology (NRIET), also known as the China Electronics Technology Company's (CETC's) No. 14 Research Institute. In December ...

  8. Traffic collision avoidance system - Wikipedia

    en.wikipedia.org/wiki/Traffic_collision...

    A traffic alert and collision avoidance system ( TCAS, pronounced / tiːkæs /; TEE-kas ), is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft. It monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder, independent of air ...

    The neural correlates of consciousness ( NCC) are the minimal set of neuronal events and mechanisms sufficient for the occurrence of the mental states to which they are related. [2] Neuroscientists use empirical approaches to discover neural correlates of subjective phenomena; that is, neural changes which necessarily and regularly correlate ...
