Abstract: Methods, systems, and computer readable media may facilitate the transport of content and playback position information from one media device to another. In embodiments, a wireless device such as a bi-directional remote control unit (e.g., Bluetooth, or RF4CE (radio frequency for consumer electronics)) or other device configured to receive and transmit wireless communications may be used to download, from a media device, and temporarily store information associated with content being output by the media device, wherein the information includes an identification of the content being output and an identification of a current playback or resume point within the piece of content. The wireless device may transmit the information associated with the content to a second media device, and the second media device may use the information to retrieve the piece of content identified by the information and to initiate playback of the content from the position identified by the information.

Abstract: The present invention discloses a means of the generation of tunable femtosecond pulses from 380 nm to 465 nm near the degenerate point of a 405-nm pumped type-I BBO non-collinearly phase-matched optical parametric amplifier (NOPA). The tunable UV/blue radiation is obtained from sum frequency generation (SFG) between the OPA output and the residual fundamental beam at 810-nm and cascaded second harmonic generation (SHG) of OPA. With a pumping energy of 75 mJ at 405 nm, the optical conversion efficiency from the pump to the tunable SFG is more than 5% and the efficiency of SHG of the OPA is about 2%.
