A method of using an oximeter sensor assembly including the steps of detecting light from a light emitting element and storing digital data in a memory associated with the sensor assembly. Also disclosed are an optical element having a sufficient optical performance without surface cracks, cloudiness, scratches, and the like and a method for manufacturing the same. The first lens group includes a positive meniscus lens with the concave surface facing the object side and one or more cemented lenses, the first lens group having a positive refractive power as a whole, at least one of the cemented lenses includes a lens made of a material having an Abbe’s number equal to or larger than 80, and conditions 0. If there is neither I picture nor P picture, the last B picture is output. By its configuration, the weight distribution of a device according to the invention is such that it may be used for extended periods by an operator without undergoing fatigue. The method includes, when the UE initiates a handover from a first cell that is providing the MBMS, the UE adding a TMGI associated with the MBMS service to a message sent from the UE to an access node in the first cell.
