Abstract: Disclosed is a system, method, and apparatus for quantification and feedback of eye deviations during normal viewing conditions. A sensory biofeedback system serves to emit a sensory cue such as a tone or vibration when a certain threshold of eye deviation has been exceeded. The biofeedback system allows objective monitoring of the accuracy of eye alignment that can be used outside of a clinical setting or inside a clinical setting.

Abstract: A portable sign having a two axis adjustable mounting requiring no tools for adjustment. The sign may be an electronically programmable flat sign. The mounting may comprise at least one linear slidably adjustable arm configured for varying a position of the arm. The arm may have a suction cup attached thereto by a flexible band wrapping around the arm. The flexible band configured to allow rotation around the arm in a plane perpendicular to the arm. The flexible band having detents molded therein to ensure secure retention of the weight of the sign at any detent stop position. The sign may have a housing with slots running the length of the sign for attaching the arms. The housing may be extruded and may include board mounting and end cap attachment features in the extrusion. The sign may typically include four adjustable arms; however any number may be used.
