Abstract: Beam manipulation member for use in an optical tweezers system, the beam manipulation member comprising at least one optical element, being controllably deformable in order to act on a laser beam in response to signals coming from the optical tweezers system. The beam manipulation member may be used to change the focal distance of the optical tweezers system and also to deflect the laser beam.

Abstract: In order to provide a resonator structure (100) in particular a bulk-acoustic-wave (BAW) resonator, such as a film BAW resonator (FBAR) or a solidly-mounted BAW resonator (SBAR), comprising at least one substrate (10); at least one reflector layer (20) applied or deposited on the substrate (10); at least one bottom electrode layer (30), in particular bottom electrode, applied or deposited on the reflector layer (20); at least one piezoelectric layer (40), in particular C-axis normal piezoelectric layer, applied or deposited on the bottom electrode layer (30); at least one top electrode layer (50), in particular top electrode, applied or deposited on the bottom electrode layer (30) and/or on the piezoelectric layer (40) such that the piezoelectric layer (40) is in between the bottom electrode layer (30) and the top electrode layer (50), it is proposed that at least one dielectric layer (63, 65) applied or deposited in and/or on at least one space in at least one region of non-overlap between the bottom electro

Abstract: A method is proposed for maintaining uplink synchronization with P2P communication in wireless communication networks, comprising steps of: the wireless communication system overhears the P2P communication between two UEs (user equipments), determines the SS (synchronization shift) information of said UEs according to the overheard information transferred by each UE in P2P communication, and transmits the SS information to the corresponding UE via the downlink common control channel; the UE monitors the downlink common control channel, and adjusts the TA (timing advance) for transmitting signals according to the SS information transferred via the downlink common control channel.
