Abstract: The present disclosure provides systems, devices, and methods for penetrating a biological membrane. The system may comprise a laser unit configured to generate one or more laser beams. The system may comprise a set of targeting optics configured to direct the one or more laser beams to a target region of the biological membrane. The system may comprise a raster scanner operatively coupled to the laser unit and the set of targeting optics. The system may comprise a non-transitory computer readable storage medium comprising a set of instructions. The set of instructions may be configured to control at least one of the laser unit, the set of targeting optics, or the raster scanner to photodisrupt the target region of the biological membrane to a target depth while minimizing damage to one or more blood vessels in proximity to the target region.

Abstract: A wireless device for use in an ad hoc network is provided. The wireless device includes a transceiver, a global positioning system, and a controller. The transceiver is capable of receiving positional information from a plurality of remote users. The global positioning system is capable of generating positional information regarding the wireless device. The controller selects a first portion of the plurality of remote users to be within a pro active region of the ad hoc network based upon the positional information, and then maintains information on the remote users selected to be within the pro active region.

Abstract: What is disclosed is a lifting apparatus, in particular a ferry landing stage, comprising a platform that is capable of being taken into a predetermined lift position with the aid of a hydraulic cylinder or of a cable winch. A safety stop by which the platform may be supported independently of the drive mechanism is associated to the drive mechanism.

Abstract: A focally-controlled imaging system comprises a tracking system adapted to monitor a spatial focal point of a user and a virtual imager adapted to generate a virtual representation of an object for display to the user. The virtual imager is adapted to focalize the virtual representation corresponding to the spatial focal point of the user.
