A bracket and a wall mount equipped with the bracket are disclosed. It is determined whether an endpoint exhibits significant activity. b) A video output signal conditioner, coupled to the APS array, for multiplexing and amplifying the photoelectric signals into the VOS with an electric signal gain GEE. A candidate list of venues having the highest link strength with the combined personality matrix may be determined. The above steps are then repeated until all of the peak summits on the contour are identified. A subset of the second electrodes is applied with a second voltage to generate electrostatic force between the subset of the second electrodes and a user’s finger in the second haptic mode.
