Abstract: A liquid crystal composition includes at least one liquid crystal compound of a general formula (I), at least one elastic constant regulator of a general formula (II), and at least one chiral compound. A light modulating device with the liquid crustal composition has at least two stable states in the absence of applied voltage, at least one state allowing incident light to pass through substantially (transparent state), and at least one state scattering incident light substantially (foggy state). The transparent state and the foggy state may be switched by means of an external electric field. The transparent state is clear and highly transmissive, while the foggy state provides privacy protection. By introducing a bimesogenic compound and adjusting the helical pitch of the liquid crystal composition system to P?3.5 ?m, the uniformity of the planar arrangement of the liquid crystal composition molecules is improved and texture defects are reduced.

Abstract: Embodiments described herein relate to managing access to an embedded universal integrated circuit card (eUICC) to obtain subscriber identity module (SIM) information without requiring cellular baseband wireless processing support. A baseband component of a wireless device that connects to the eUICC via a first interface can be in a reduced power state, and under certain conditions a processor external to the eUICC can access the eUICC via a second interface without booting up the baseband component to a normal (full) power state. When access to the eUICC via the first interface through the baseband component is required, the baseband component can be booted to a normal (full) power state to communicate with the eUICC. Additionally, a wireless device in which the baseband component is in a reduced power state or is absent can access one or more services of a mobile network operator (MNO) via a non-cellular wireless interface.

Abstract: This application describes managing configuration of a bootstrap electronic SIM (eSIM) for a wireless device. A bootstrap eSIM on an embedded universal integrated circuit card (eUICC) of the wireless device is configured as needed to provide cellular wireless access. The bootstrap eSIM is configured with an initial international mobile subscriber identity (i-IMSI) value used to establish a cellular connection to obtain a bootstrap IMSI (b-IMSI) value allocated for temporary, dedicated use by the wireless device. The b-IMSI value is selected by a bootstrap server based on a bootstrap selection rule obtained from a bootstrap rules service, where the bootstrap selection rule accounts for a use case type provided by the wireless device and indicating a purpose for use of the b-IMSI value. The b-IMSI value is returned to a pool for use by other wireless devices after expiration of a timer or responsive to a delete notification message.
