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.
Sensation refers to the process by which we detect physical energy from the environment and encode it as neural signals. This chapter describes the senses of vision, hearing, taste, touch, smell, kinesthesis, and the vestibular sense. It also presents research findings from studies of subliminal stimulation.
