Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a radio resource control (RRC) reconfiguration message. The UE may reestablish a radio link control (RLC) entity based on receiving the RRC reconfiguration message and transmit an indication that the RLC entity has been reestablished at the UE. In some cases, the UE may receive a data message prior to receiving an acknowledgment for the indication that the RLC entity is reestablished. For example, the base station may retransmit the RRC reconfiguration message prior to sending an acknowledgment status report. The UE may discard the data message based on the data message being received prior to receiving the acknowledgment.

Abstract: Systems tune, control, or remediate the intrinsic Circadian clock. A light controller sets spectral distribution, intensity of a bioactive spectral band to shift or entrain circadian response to enhance performance and/or synchronize with local or expected conditions. The systems enhance performance under conditions that might be changing, disrupted, or otherwise present an irregular phase or unnatural change in the subject's circadian status, for example, due to geographically discontinuous activity or spectrally deficient workplace illumination, or due to divergent individual sleep/wake behaviors of subjects in a structured group activity. An illumination recipe that compensates for the deficiency of lighting or of participant sleep or behavior patterns, or age- or disease-related changes, to evoke, shift, or align circadian response and improve behaviors such as classroom alertness, relaxation, excitability, attention, or focus.

Abstract: Method and apparatus for reducing distortion echo are provided. K-path amplification and pre-distortion process are performed to the downlink reference signal to obtain K-path pre-distorted signals. Afterwards, filtering is performed using the self-adaptive filters which correspond to the downlink reference signal x(t) and the K-path pre-distorted signals to obtain the filtering signals. Error signals are obtained by calculating differences between the target signal and each of the filtering signals. The minimum-value fusion process is performed to the error signals to obtain the residual signal which is then output as the final self-adaptive echo cancellation. In embodiments of the present disclosure, the residual signal is relatively small as the minimum-value fusion process is performed to the error signals. That is to say, echo loss is relatively great. Therefore, the method may provide echo loss with high amplitude under a situation that a speaker has relatively serious distortion.

Abstract: A method of switching between noise reduction modes in multi-microphone mobile devices may include receiving a first sound signal at a first sound receiver and receiving a second sound signal at a second sound receiver. The method may also include determining a first power value associated with the first sound signal and determining a second power value associated with the second sound signal. The method may additionally include comparing the first power value to the second power value and switching between a single-microphone noise reduction mode and a dual-microphone noise reduction mode based on the comparison.

Accordingly, the present disclosure realizes steadily providing a relatively high echo loss under a circumstance that a speaker suffers a relatively great distortion.

Abstract: Systems and methods for signal noise reduction. An input digital signal may be partitioned into a series of adjacent segments. The adjacent segments may be converted to a frequency domain representation. A particular spectral component of a particular segment may be compared to a related spectral component of a first segment adjacent the particular segment, and to a related spectral component of a second segment adjacent the particular segment. The particular spectral component may be modified upon a magnitude value of the particular spectral component satisfying at least one of a predetermined set of conditions.

Abstract: Devices and methods are provided for a nanocomposite having a phase change polymer matrix and conductive nanoparticles to provide greatly enhanced responsivity to temperature and/or humidity. A sensing film includes carbon nanotubes (CNTs) and the polymer. Operation near the transition temperature increases the TCR by over an order of magnitude, thus providing a new platform for devices such as IR sensors, bolometers and imaging elements, MEMS devices, compensating or uncompensated circuit elements and other electronic devices. Nanocomposite films may be under about one micron thick, and coatings, constant environment chambers or mounts, and other engineered improvements and variations may be provided to further enhance the response, range, response times or sensitivity of the film-based devices. One embodiment employs a nanocomposite film under one micron in thickness to operate as an uncooled but highly sensitive infrared bolometer under ambient conditions.

The method includes: obtaining a first GRMV (global relative motion vector) of a current video frame relative to its previous video frame, and a sequence of second GRMVs of reference video frames relative to their respective previous video frames; calculating a sequence of third GRMVs of the reference video frames relative to the current video frame, respectively, based on the first GRMV and the sequence of second GRMVs; and filtering the sequence of third GRMVs to obtain a motion vector for compensating shaking of the current video frame. Camera shaking and intended motion can be distinguished.

Abstract: A method and nanoparticle construct provides shielded delivery of a drug or agent to a tissue or treatment site, and release of the agent may be triggered externally. Carbon nanotubes (CNTs) are filled with the therapeutic agent in a temperature sensitive gel, and release of the agent is effected by inductive heating, e.g. applying an alternating or pulsed magnetic field, or electrical field. The CNTs may be functionalized for solubility, drug absorption, responsivity to pH, enzyme catalysis, and/or ambient biological environment. Encapsulation within the nanostructure protects the intracorporal or surrounding cellular environment from the potentially toxic cargo and prevents the degradation of the cargo during delivery. By releasing at or in the target tissue extremely small amounts of the agent may achieve an effective level of treatment, as measured by cell apoptosis, tumor shrinkage or other treatment effect while safely avoiding systemic damage.
