A beam-scanning optical design is described for achieving up to kHz frame-rate optical imaging on multiple simultaneous data acquisition channels. Each contact element includes a conductive portion disposed to engage a respective pad of a land grid array module for providing electrical connection to the land grid array module. Upon receiving a request at the service broker processor to register a network resource to provide a network service, the service broker processor authenticates the request and authorizes registration in the service broker registry. The powershiftoverload clutch is axially disposed between the drive ring and a clutch sleeve for a spring. The composition, when cured, is non-yellowing, exhibits low shrinkage and low birefringence making it suitable for many optical applications such as optical lenses, optical fibers, prisms, light guides, optical adhesives, and optical films. The home network module is adapted for connection to a home electronic device.
