The present disclosure provides certain tetrahydro-1H-cyclopenta[cd]indene compounds that are Hypoxia Inducible Factor 2α (HIF-2α) inhibitors and are therefore useful for the treatment of diseases treatable by inhibition of HIF-2α. Also provided are pharmaceutical compositions containing such compounds and processes for preparing such compounds.

Methods, systems, and apparatus for monitoring and controlling electronic devices using wired and wireless protocols are disclosed. The systems and apparatus may monitor their environment for signals from electronic devices. The systems and apparatus may take and disambiguate the signals that are received from the devices in their environment to identify the devices and associate control signals with the devices. The systems and apparatus may use communication means to send control signals to the identified electronic devices. Multiple apparatuses or systems may be connected together into networks, including mesh networks, to make for a more robust architecture.
