Abstract: The invention relates to a method for enhancing a surfactant, in particular a pulmonary surfactant, as well as a method for producing a surfactant enhancement agent, in particular a pulmonary surfactant enhancement agent. The invention also relates to a surfactant enhancement agent and a use of an enhancement agent for enhancing a surfactant, in particular, a pulmonary surfactant. Further, the invention relates to a method of mitigating oxidative damage to pulmonary surfactant by adding a cholesterol-sequestrating agent such as cyclodextrin. Finally, a method is provided for treating a patient having surfactant dysfunction due to oxidative damage to pulmonary surfactant by administering a surfactant-protective amount of a cholesterol-sequestrating agent to protect the surfactant from the negative effects of oxidative degradation.

Abstract: A RF switch may be used as a power splitter in order to allow WLAN and Bluetooth (BT) coexistence. Multiple branches of the RF switch are enabled concurrently, which allows WLAN and BT signals to be received simultaneously. The RF switch functions as a power splitter to split signals received from an antenna to both a WLAN receiver and a BT receiver. In one embodiment, a second switch may be placed on an output of a low noise amplifier (LNA). This configuration will operate as a power splitter between WLAN receiver port and a BT port, and maximize the receiver sensitivity by amplifying both the WLAN and BT signals. One or both of the two switches may also function to bypass the LNA when the LNA is not needed to provide a low loss RF path, which serves to broaden the dynamic range of the device and avoid signal distortion during periods of increased signal power.
