Abstract: A first playback device can include a wireless network interface, an audio input interface, one or more processors, and data storage. The data storage stores instructions that, when executed by the processors, cause the first playback device to determine a first radio frequency (RF) energy level associated with RF signal communications from a second playback device to the first playback device. The first playback device modifies a threshold RF energy level for holding off transmissions by the first playback device based on the first RF energy level. The first playback device receives multi-channel audio content via the audio input interface and detects an ambient RF energy level.

Abstract: Apparatuses and methods for setting a duty cycler adjuster for improving clock duty cycle are disclosed. The duty cycle adjuster may be adjusted by different amounts, at least one smaller than another. Determining when to use the smaller adjustment may be based on duty cycle results. A duty cycle monitor may have an offset. A duty cycle code for the duty cycle adjuster may be set to an intermediate value of a duty cycle monitor offset. The duty cycle monitor offset may be determined by identifying duty cycle codes for an upper and for a lower boundary of the duty cycle monitor offset.

Abstract: An apparatus for determining a height of an abject includes a camera to acquire a two-dimensional (2D) image and a processor. The processor detects a target object corresponding to an obstacle from the 2D image. The processor also determines a reference lower point from among pixels positioned at a lower portion of the target object. The processor further projects a preset reference line to the 2D image such that a reference point of the preset reference line is matched with the reference lower point. The processor additionally determines a height of the target object based on at least one threshold value for marking a preset distance, from the reference point, on the reference line.

Abstract: A composition for enhancing radiation therapy includes a complex including micelles formed of amphiphilic molecules in which a hydrophilic portion and a hydrophobic portion are bound by a reactive oxygen species (ROS) cleavable linker, and manganese oxide particles supported on cores of the micelles and hydrophobically modified by binding a hydrophobic substituent to the surface thereof. By supporting hydrophobic manganese oxide particles in the micelles, the complex is stably protected in vivo and easily delivered to a tumor site. The micelles have a hydrophilic portion and a hydrophobic portion bound by a ROS cleavable linker to be degraded in response to a ROS of a target site, and thus can efficiently release the hydrophobic manganese oxide particles. The released hydrophobic manganese oxide particles generate oxygen and changes the microenvironment of the target site, and thus may enhance the therapeutic effect of a drug carried on the micelles.
