This invention introduces methods and mechanisms of partial integrity protection in mobile systems. A user equipment (UE), comprising: a memory configured to store instructions; and a processor configured to execute the instructions to: receive, from a network device, user plane data having integrity protection; send an error indication indicating an integrity protection error relating to the user plane data; and receive retransmitted user plane data from the network device with a reduced data rate, based on the error indication.

Schemes and methods of integrity protection in mobile communication

A light-receiving unit containing four optical sensors arranged crosswise and a light-shielding body containing four through-holes confronting light-receiving surfaces of the optical sensors, and a tilt adjustment mechanism containing first and second movable bodies which are mounted on first and second rotation shafts arranged on a same plane to cross at right angles are provided. The tilt adjustment mechanism is mounted in a housing constituting a ceiling-mounted type lighting device and the light-receiving unit and a lighting lamp are mounted on a rotational center axis of the second moving body. Tilt adjustment light emitted from a treatment table hits the optical sensors via the light-shielding body.
