Abstract: A cable management apparatus of an electric vehicle charging station for managing an electric vehicle charging cable is described. The cable management apparatus comprises a housing and a swing arm. The housing houses a hub connected to a swing arm housing to allow the swing arm housing to rotate about the hub from a starting position to an ending position. The housing further houses a damper, where a first end is attached to the housing of the cable management apparatus and a second end is attached to the swing arm housing to manage retraction of the swing arm housing. The housing further houses a first rotation stop element to prevent the swing arm housing from rotating beyond the ending position. The cable management apparatus further comprises the swing arm housing connected to the housing of the cable management apparatus by the hub and the second end of the damper.

Abstract: In accordance with the invention, a tunable subwavelength resonant grating filter comprises a liquid crystal cell having a pair of major surface walls. One wall of the cell is a coated subwavelength grating of a SRGF. The coating comprises a polymer layer to fill the grating trenches and a surfactant layer to facilitate uniform alignment of the liquid crystal material. The refractive index of the LCD material in the cell can then be electrically or thermally adjusted to tune the resonant wavelength.
