Abstract: A spa cover lift is disclosed. The spa cover lift includes a support structure, and a lifting structure coupled to the support structure, the lifting structure having an actuator configured to store and release energy during lifting and storing of a spa cover. Embodiments of the spa cover lift include an electro-mechanical actuator configured to move the spa cover from between a “covered state” and a “stored state.

Abstract: Circuitry of an optical line terminal (OLT) can be controlled to be compatible with optical modules of different optical protocols having different electrical connectivity requirements. In some embodiments, the OLT has a controller that is configured to communicate with an optical module plugged or otherwise mated with a socket of the OLT in order to discover a module type of the optical module. Based on the detected module type, the controller is configured to control the electrical characteristics of the OLT circuitry so that it is compatible with the electrical and operational requirements of the optical module. Thus, the OLT is compatible for use with any of a plurality of optical module types.

Abstract: A spa cover is disclosed. The spa cover includes two separate and symmetrical halves comprising an insulating portion, a half hourglass-shaped insulating gasket, a resilient thermal gasket, and a tapered gasket spanning a bottom surface thereof and a sheet covering both halves. The two separate and symmetrical halves are joined by a hinge, which may be part of the sheet.

Abstract: A spa cover is described that is comprised of a plurality of inflatable drop stitch bladders and a slipcover comprising a plurality of separate chambers. Each chamber corresponds to a respective one of the plurality of inflatable bladders, and each chamber is constructed to house a corresponding one of the inflatable bladders therein. The slipcover has a hinge between at least two separate chambers.
