Fault recovery of video bitstream in remote sessions
Fault recovery of a video bitstream can be performed in a remote session. A decoder of a remote display protocol client can be configured to process a video bitstream that is transferred over a virtual channel of a remote session. As part of processing the video bitstream prior to passing it to a hardware decoder, the decoder can detect the occurrence of an error in the bitstream and then cause the remote display protocol client to employ the remote display protocol which encapsulates the virtual channel to request an I-frame from the remote display protocol service. This will force the encoder to send an I-frame even if the desktop has low entropy thereby minimizing how long a glitch may persist. Because the remote display protocol itself is employed to request the I-frame, there is no requirement to modify the video stream protocol. |

Preventing sub-harmonic oscillation with clock delay compensation, in a DC-DC switching converter
The clock input of a buck converter is delayed, and the delay is controlled proportionally to the preceding high-side output switch on time. In the steady state, the high-side switch on time is uniform, and the clock is offset by a fixed amount. When sub-harmonic oscillation begins to occur, the high-side switch on time may increase during a cycle. The longer high-side on time causes the clock to be delayed by an increased amount. This has the effect of increasing the following low-side output switch on time. This further increases the subsequent high-side on time, and counteracts the effects of sub-harmonic oscillation. If the system is properly controlled, loop compensation is implemented correctly and sub-harmonic oscillation is prevented. In addition, the scheme may also be configured for the delay to be controlled proportionally to the preceding low-side output switch on time of the buck converter. |

Germanium tin oxide thin films for uncooled infrared detection
Microbolometer is a class of infrared detector whose resistance changes when the temperature changes. In this work, we deposited and characterized Germanium Oxide thin films mixed with Sn (Ge—Sn—O) for uncooled infrared detection. Ge—Sn—O were deposited by co-sputtering of Sn and Ge targets in the Ar+O environment using a radio frequency sputtering system. Optical characterization shows that the absorption in Ge—Sn—O was most sensitive in the wavelength ranges between 1.0-3.0 μm. The transmission data was further used to determine the optical energy band gap (0.678 eV) of the thin-film using Tauc's equation. We also found the variations of absorption coefficient (1.4802×105 m−1-1.0097×107 m−1), refractive index (1.242-1.350), and the extinction coefficient (0.3255-8.010) for the wavelength ranges between 1.0-3.0 μm. The thin film's resistivity measured by the four point probe was found to be 4.55 Ω-cm and TCR was in the range of −2.56-−2.25 (%/K) in the temperature range 292-312K. In light of these results it can be shown that this thin film is in keeping with the current standards while also being more cost and time effective. |
