摘要:
A system for amending implementation instructions for any number or combination of Emergency Auxiliary Services, the Emergency Auxiliary Services being effected according to the implementation instructions regarding at least one predetermined receiver after a triggering communication is placed from a subscribing communication instrument includes: (a) A change ordering means for effecting the amending. The change ordering means is exercised by a service requesting entity using the subscribing communication entity. (b) An instruction amending means coupled with the subscribing communication entity. The instruction amending means responds to the change ordering means to effect the amending.
摘要:
A device for checking a container neck for the presence of an incline is disclosed. A pressure-contact head, which can be lowered onto the container, has means for holding and centering the container. A checking part, which can be moved angularly relative to the horizontal, is urged onto the neck and correlates in its angular position relative to the horizontal plane with the incline of the neck. Means for scanning the angular position of the checking part relative to the horizontal plane are provided along with an evaluating unit which uses measurement values provided by the scanning means to generate an information signal relating to the incline of the neck. An actuator, controlled by the evaluating unit, screens the container and rejects it if the information signal is beyond a permissible threshold value.

An apparatus for finely synchronizing code signals with an encoded received signal includes a sampling device for sampling the received signal at regular sampling intervals, a pulse shaper for shaping the sampled received signal pulses in order to output a first and second pulse-shaped sample in dependence on an autocorrelation function, a buffer for buffering the two samples, a code signal generator for generating the code signal, correlation devices for correlating the generated code with the two buffered samples to form two correlation values, and an interpolation device for forming an interpolation value as a function of the two pulse-shaped samples and the deviation between the two correlation values.
摘要:
A method for synchronizing a mobile radio receiver with a frame structure of a radio signal received from a specific base station assumes that each base station transmits a predefined, individual sequence of frame synchronization codes for each frame. The synchronization codes are detected and decoded in the mobile radio receiver and a characteristic code parameter is allocated to them. The sequence transmitted by the specific base station is identified on the basis of the code parameters and the start and end times of the sequence are defined. The mobile radio receiver is frame-synchronized with these times.

The method and device enable determining the carrier frequency of base stations in the mobile receiver of a cellular mobile radio system working with W-CDMA. The carrier frequency of the primary synchronization channel of the strongest received base station is first searched for by carrying out a non-coherent correlation of the received signal with the primary synchronization code over a very large number of code elements of the signal.
摘要:
A device for holding an object, and an assembly for holding and rotating an object. The device includes a base, a series of posts, each of which is equidistant from a center point of reference and further pivotably holds a follower rotationally linked to all other followers. Each follower has a gripping portion dimensioned to hold an object. An actuator serves to displace the followers radially about the post holding it creating a motion that causes the gripping portions to move either towards or away from the center reference point, dependent upon the displacement of the actuator. As all followers are rotationally linked, each follower of the device rotates to a substantially equal degree.
摘要:
A method is described for estimating channel impulse responses of a mobile radio channel with a broad bandwidth by a code division multiplexing method, and with a synchronization channel continuously transmitting sequences to mobile radio receivers. The sequences are provided for synchronization of each mobile radio receiver and are known to each of the mobile radio receivers. The transmitted sequences have pilot symbols for identifying the synchronization channel, and the pilot symbols are transmitted at points that are known to the receivers within a time slot. When searching for and identifying the synchronization channel, the pilot symbols and, possibly, further symbols and sequences which are known in the receivers, are evaluated to estimate the delay times and the complex amplitudes, of the mobile radio channel responses.
