Apparatus and associated methods relate to a system including a portable hardware device having a radio antenna, the device being operably coupled to a network, where the device includes electronics for scanning ambient radio messages
Apparatus and associated methods relate to enabling a radar system to use different sensing mechanisms to estimate a distance from a target based on different detection zones (e.g., far-field and near-field). In an illustrative example,
Apparatus and associated methods relate to powering a constant voltage DC load using a rectified output of a lighting ballast. In an illustrative example, the ballast may be configured to operate as a constant-current source.
Apparatus and associated methods relate to a method of non-contact motion detection. A one-dimensional optical sensor detects motion of a target or objects on a conveyor belt through a continuous measurement of targets or objects
