Abstract: Systems and methods related to “on/off” determinations regarding the performance of physical downlink control channel (PDCCH) monitoring during connected mode discontinuous reception (CDRX) on duration windows are disclosed herein. In some cases, a radio access network (RAN) predicts whether a downlink (DL) packet for a UE will arrive at a buffer of the RAN prior to an end of a CDRX on duration window of the UE, and sends a downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a power-saving radio network temporary identifier (PS-RNTI) (DCP) for the CDRX on duration window indicating whether or not the UE should perform PDCCH monitoring during the CDRX on duration window based on the prediction. In some cases, a UE determines a current state of DL traffic and adaptively uses DCP monitoring based on the current state of the traffic. Aggregation level adaptation by the RAN is also discussed.

Abstract: Provided is a preparation method for a tube. The method comprises the following steps: a) adding a polymer solution into a poor solvent, such that the polymer diffuses on the liquid level of the poor solvent, so as to obtain a polymer film, wherein the solvent in the polymer solution is dissolved in the poor solvent; b) curling the polymer film on the liquid level of the poor solvent by using a mold to obtain a bar; and c) removing the mold to obtain a tube. The present invention further provides the use of the above tubular as an artificial tubular tissue.

Abstract: For many hearing assistive devices, the user's speech is received at a larger amplitude signal than the speech of someone speaking to the user. Since the user's speech is also picked up by the microphone and feed through the speaker causing an acoustic feedback effect, the user may have to constantly adjust the volume of the hearing assistive device to achieve a more comfortable volume based on where the speech is coming from. Therefore, mitigating the acoustic feedback effect of assistive hearing devices can generate a more efficient and comfortable hearing device.

Abstract: With regards to a hearing assistive device, a user's speech can be picked up by the microphone and feed through the speaker causing an acoustic feedback effect. The user may have to constantly adjust the volume of the hearing assistive device to achieve a more comfortable volume based on where the speech is coming from. Furthermore, the when the hearing assistive device experiences feedback, the amplification of the feedback can cause damage to the user's hearing. Therefore, mitigating the acoustic feedback effect of assistive hearing devices can generate a more efficient and comfortable hearing device. The acoustic feedback can be mitigated by leveraging a dynamic range controller and a howling detector which comprises a user interface and a status indicator.

Abstract: Enhancing audio content based on application of different gains to different frequency bands of an audio signal is disclosed. Audio information contained in an input signal can undergo beamforming to provide an initial adjustment to the audio information, e.g., noise reduction, etc. In an embodiment beamforming can comprise double-beamforming in which first audio information is adjusted based on second audio information and the second audio information is adjusted based on the first audio information. Different gains can be applied to content in determined frequency bands, resulting in an amplified signal. In some embodiments, the gains can be related to hearing sensitivity of a listener, e.g., via a hearing sensitivity model. The amplified audio information from each frequency band can then be recombined. The recombined signal can be level limited and subjected to further digital and analog gains. The resulting output, e.g., enhanced audio, can be individually adapted for a listener.
