A memory system includes a memory controller and a memory component coupled to each other. An interface of the memory component is configured to receive a first signal from the memory controller with read request information, retrieve the read data information from the memory core in response to the request information, and transmit to the memory controller a second signal containing the read data information. The read data information includes read data symbols, where the average duration of the read data symbols, measured at the interface, defines a symbol time interval. A first external access time is measured at the interface between a first read request and read data transmitted by the interface in response to the first read request. A second external access time interval is measured at the interface between a second read request and read data transmitted by the interface in response to the second read request. The difference between the first external access time and the second external access time is greater than one-half of the symbol time interval.

Method of automatically processing a speech signal which comprises the steps of:determining a sequence of probability models corresponding to a given text;determining a sequence of acoustic strings corresponding to the diction of the given text;aligning between the sequence of acoustic strings and the sequence of models; anddetermining a confidence index of acoustic alignment for each association between a model and an acoustic segment.Each determining step of an alignment confidence index is carried out at least from a combination of the model probability, a priori model probabilities and the average duration of occupancy of the models.

A billing method and billing system to determine usage fees which are charged to the user of a digital telecommunications network, whereby a usage fee charged for a connection is determined prior to establishing this connection from statistical characteristics of previous connections of the user, is described. Usage fees are determined from a dynamic client profile, derived from one or multiple random variables of previous connections of the user, which is stored in memory and rederived after each new customer connection. In a simple variant, the client profile contains a value proportional to the average price per connection or to the average duration of a connection of the user. The random variables used to derive the client profile include, for example, the connection duration, the time of day, the day of the week, and / or geographic characteristics of previous connections.

The invention discloses a method and device for identifying uterine contraction based on uterine eletrohystrogram signals, and belongs to the technical field of delivery monitoring. The method comprises the steps of collecting the uterine eletrohystrogram signals within a certain duration; preprocessing the uterine eletrohystrogram signals to remove interference; setting the length of windows as L, and extracting features of the uterine eletrohystrogram signals in the windows; adopting a fuzzy clustering algorithm to cluster all features of the windows into two types, wherein if the center distance of the two types of features is smaller than or equal to a set threshold value D, it is regarded that no uterine contraction signal exists, and if the center distance of the two types of features is larger than the set threshold value, it is regarded that the type with the largest type center value is the type corresponding to the uterine contraction; calculating the time interval of the centers of every two windows in the uterine contraction types; in all the newly generated windows, searching for the starting point, the end point and the peak point of the uterine contraction; calculating uterine contraction parameters, wherein the uterine contraction parameters comprise the uterine contraction frequency, the average lasting time, the average intensity and the average interval. By means of the method and device for identifying the uterine contraction based on the uterine eletrohystrogram signals, the uterine contraction signals are automatically recognized, the uterine contraction feature parameters are calculated, and a new means is provided for monitoring the uterine activities.

A method controls the operation of devices which communicate over a wireless communications channel. The method includes determining a parameter of a received signal communicated over the wireless communications channel and determining a minimum threshold value of the received signal. An average duration of fade is determined using the parameter and the minimum threshold. The method detects whether the received signal is less than the minimum threshold value. At least one of the devices is placed in a sleep mode for approximately the average duration of fade in response to the received signal being detected as less than the minimum threshold value. The determined parameter of the received signal may be the root mean square value of the received signal.

To evaluate an energy level of a signal received through a radio interface between radiocommunication stations, successive measurement samples depending on the energy of the signal are obtained, and an average of said samples is calculated, to evaluate the energy level. The calculation of the average of the samples is performed with an averaging duration depending on a service to which the received signal pertains.
