Abstract: Techniques for implementing an internal optical communication link in a power amplifier system are disclosed. In one embodiment, the techniques may be realized as a power amplifier system that includes a panel, an optical link, and a controller. The panel includes a plurality of signal endpoints and a first optical interface, the first optical interface being coupled to each of the plurality of signal endpoints. The optical link is coupled to the first optical interface. The controller is configured to manage operation of the power amplifier system and is coupled to the optical link via a second optical interface. The controller communicates with each of the plurality of signal endpoints over the optical link.

Abstract: A reward point system comprising an industry vertical reception unit for receiving a user selected monetary value in a selected industry vertical, a point collection unit for receiving a quantity of points associated with the monetary value in the selected industry vertical, a redemption vehicle profile creation unit for generating a profile, and a redemption vehicle generation unit for loading the profile onto a redemption vehicle wherein the points on the redemption vehicle can be redeemed at any merchant in the selected industry vertical. Also provided are methods for utilizing said system.

Abstract: A non-conductive housing retains a small battery slidably within a recess in the housing. An electrically conductive clip or plate holds the battery within the recess. In an "off" position the battery contacts the non-conductive housing. Moved to the "on" position the battery contacts a thin conductive layer bonded to the housing, thereby completing and adding power to a circuit connected with the clip and an electrical or electronic element or device to be powered. Lighted or sounding jewelry or other small items containing an electrical element are applications. Additional positions of the movable power source may control other circuits causing other electrical and electronic effects such as flashing or sequential lights.
