Within that key, you can have multiple REG_BINARY values, where the value name is the paired device's MAC address (in same form -- hex, lowercase, no separators) and the value is the link key (16 bytes).
What does it mean to sense something? Sensory receptors are specialized neurons that respond to specific types of stimuli. When sensory information is detected by a sensory receptor, sensation has occurred. For example, light that enters the eye causes chemical changes in cells that line the back of the eye. These cells relay messages, in the form of action potentials (as you learned when studying biopsychology), to the central nervous system.
1 Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System (i.e. the brain and spinal cord, sometimes referred to in the abbreviated form: C.N.S.). 2  This is happens because peripheral nerves connect to the spinal cord via the network of nerves within the nervous system. (Stimuli is the plural form, referring to more than one stimulus.). 2  In this context, a stimulus is something that human sensory receptors are able to detect. 3  E.g. sounds, physical contact, tastes, visual sensation, etc..
