A microscope or stereomicroscope for representing an object that can be placed on an object plane of the stereomicroscope provides at least one pair of optical paths and comprises at least one deflection element with a reflecting surface and a representation system containing several optical elements. The optical elements include a plurality of lenses. In addition, the optical elements are configured in such a way that pupil planes of the optical representation paths intersect the reflecting surface of the deflection element or are located at a distance from said reflecting surface less than 1.5 times the diameter of one of the reflecting surfaces along the optical representation paths on the closest lens of the plurality of lenses. An alternative embodiment provides a stereomicroscope with a particularly compact construction, in which at least one pair of optical representation paths is reflected on a first, second, third, and fourth reflecting surface.

Transmitter devices and transmission methods transmit a modulated GMSK- or EDGE-signal in a transmission system, wherein normally the pulse shaping follows the given rules of standards for these mobile radio systems. The amount of TX spectra in the adjacent TX channels is predetermined by these rules. A second filtering step is suggested to be introduced for attenuating predetermined unwanted spectra in the adjacent transmit channels. A second goal of this suggestion is to reduce spectra at adjacent TX channels also at cases of nonlinearity at the TX Power Amplifier of the RF transmitter. Nothing must be changed in standards of mobile communication systems, for example GSM.

Mobile User Equipment (UE) is operated in a first mode in which radio functions are enabled. In response to a predetermined condition, the UE is operated in a power saving mode involving disabling all radio functionality for a first period of time during which no connection is maintained with a cellular communication system serving node. After the first period of time, the UE ascertains whether any attempts were made to contact it during the first period of time and if so whether any of the attempted contacts is characterized by an attribute that matches a predefined attribute. If any of the attempted contacts is characterized by the attribute that matches the predefined attribute, then a user alarm is activated. If the response to the user alarm has been made, then the UE is again operated in the first mode; otherwise, the UE is again operated in the power saving mode.

A receiver (120) is configured to receive data over a communications link. A decapsulator (122) is coupled to the receiver and configured to create datagrams and erasure attributes associated with the datagrams. A decoder (124) is coupled to the decapsulator and configured to store the datagrams in a frame table (400) and to create codewords, the decoder storing the datagrams in table columns to create codewords in table rows, correcting the codewords, and configured to store the erasure attributes in an erasure table (552). The erasure table is characterized in that it comprises a plurality of entries (560), each of which is associated with a column of the frame table. Each entry is comprised of a plurality of elements (570).

A neutron porosity measurement device uses semiconductor detectors located at different distances from a cavity configured to accommodate a neutron source. Each of the semiconductor detectors includes (i) a semiconductor substrate doped to form a pn junction, and having microstructures of neutron reactive material formed to extend from a first surface inside the semiconductor substrate, and (ii) electrodes, one of which is in contact with the first surface of the semiconductor substrate and another one of which is in contact with a second surface of the semiconductor substrate, the second surface being opposite to the first surface. The electrodes are configured to acquire an electrical signal occurring when a neutron is captured inside the semiconductor substrate.

The invention relates to a method to determine the relative position of a container corner lock and/or a group of container corner locks in relation to other container corner locks. The method comprises the steps of: requesting information regarding identification from those locks (1) that are within a certain area; transferring said information to each lock (1) within said area; storing, in each lock (1) within said area, said requested information from other locks within the area; determining, based on said stored information, the relative position of the lock and/or of the group of locks. The invention also relates to a system and a container corner lock.
