1. Reflex

   In biology, a reflex, or reflex action, is an involuntary, unplanned sequence or action and nearly instantaneous response to a stimulus. Reflexes are found with varying levels of complexity in organisms with a nervous system. A reflex occurs via neural pathways in the nervous system called reflex arcs. A stimulus initiates a neural signal, which is carried to a synapse. The signal is then transferred across the synapse to a motor neuron which evokes a target response. These neural signals do not always travel to the brain, so many reflexes are an automatic response to a stimulus that does not receive or need conscious thought.Many reflexes are fine-tuned to increase organism survival and self-defense. This is observed in reflexes such as the startle reflex, which provides an automatic response to an unexpected stimuli, and the feline righting reflex, which reorients a cat's body when falling to ensure safe landing. The simplest type of reflex, a short-latency reflex, has a single synapse, or junction, in the signaling pathway. Long-latency reflexes produce nerve signals that are transduced across multiple synapses before generating the reflex response.

1. ReFLEX

   ReFLEX is a wireless protocol developed by Motorola, used for two-way paging, messaging, and low-bandwidth data. It is based on the FLEX one-way paging protocol, adding capabilities for multiple forward channels, multiple return channels, and roaming. It originally came in two variants, ReFLEX25 and ReFLEX50. ReFLEX50 was originally developed to support a messaging service launched by MTEL in the mid 1990s, while ReFLEX25 was developed several years later to provide an upgrade path for traditional one-way paging carriers. The 50 and 25 signified 50 KHz and 25KHz channel spacing, although in reality both variants supported flexible channel configurations. The two variants were unified into a single protocol with version 2.7, which was released simply as ReFLEX 2.7. Devices compliant with ReFLEX 2.7 are backwards compatible with both ReFLEX25 and ReFLEX50 networks, with several new features to improve roaming, performance, and interoperability between different networks. ReFLEX systems support forward channel speeds of 1600, 3200, and 6400 bits per second, and return channel speeds of 800, 1600, 6400, and 9600 bits per second. Like FLEX, ReFLEX is synchronous, based on 1.875 second frames and 4-level FSK modulation.
