Method for measuring concentration of substance in blood
The concentration of substance in blood is measured non-invasively, with high accuracy and with simple configuration. Laser light generated by a light source is locally irradiated on the body epithelium of a subject, and the resulting diffused reflected light is detected by a light detector. The laser light has a wavelength of 9.26 μm. The laser light is generated by converting and amplifying pulsed excitation light from an excitation light source to a long wavelength. A plate-shaped window that is transparent to mid-infrared light is brought in close contact with the body epithelium. The glucose concentration in interstitial fluid can be calculated using normalized light intensity calculated from a signal ratio of signals from a monitoring light detector and the light detector. |

Signaling of state information for a decoded picture buffer and reference picture lists
Innovations for signaling state of a decoded picture buffer (“DPB”) and reference picture lists (“RPLs”). In example implementations, rather than rely on internal state of a decoder to manage and update DPB and RPLs, state information about the DPB and RPLs is explicitly signaled. This permits a decoder to determine which pictures are expected to be available for reference from the signaled state information. For example, an encoder determines state information that identifies which pictures are available for use as reference pictures (optionally considering feedback information from a decoder about which pictures are available). The encoder sets syntax elements that represent the state information. In doing so, the encoder sets identifying information for a long-term reference picture (“LTRP”), where the identifying information is a value of picture order count least significant bits for the LTRB. The encoder then outputs the syntax elements as part of a bitstream. |

Minimizing DC bias voltage difference across AC-blocking capacitors in PoDL system
A PoDL system that uses a center-tapped transformer, for galvanic isolation of the PHY, has AC-coupling capacitors in series between the transmission wires and the transformer's secondary windings for blocking DC voltages generated by a PSE power supply. The center tap is conventionally connected to ground. As a result, one capacitor sees the full VPSE voltage across it, and the other capacitor sees approximately 0 V across it. Since the effective value of a ceramic capacitor significantly reduces with increasing DC bias voltages across it, the effective values of the capacitors will be very different, resulting in unbalanced data paths. This can lead to conversion of common mode noise and corrupt the data. To avoid this, a resistor divider is used to generate VPSE/2, and this voltage is applied to the center tap of the transformer. Therefore, the DC voltage across each capacitor is approximately VPSE/2, so their values remain equal. |
