摘要:
At least one base station of a wireless network adjusts its access area so as to drive at least one measure of utilization of a resource or resources of that cell toward, but not to exceed, a specified maximum level. The adjustment is dynamic in that it responds in real time to traffic fluctuations. The adjustment is autonomous in that it is not directed from outside the cell. The access area of the cell is determined by the received strength, at the respective users, of a beacon channel transmitted from the base station. In specific implementations, the access area may be adjusted by adjusting the effective signal transmit strength of the beacon signal, or by adjusting the tilt of the antenna that transmits to the cell.

A method for detecting packet data transmission following an inactive period of a transmitter. The method includes using a dynamic acquisition search window which grows from an initial width (determined by the size of the corresponding standard search window prior to entering the inactive period) up to a maximum width (for example, the width of a full cell) in correspondence with the length of time that the transmitter is in the inactive state. The method is particularly directed to a mobile transmitter having active and inactive periods. The method according to the present invention is also useful relative to streaming data, such as voice, including a plurality of multipath components.

The invention provides a novel, easy to use, hand-operated apparatus for effortlessly loosening the threaded lid of ajar or bottle having a screw-on lid and readily accommodates jars or bottles of different sizes. One form of the invention includes a base having a jar supporting surface, a generally vertically extending guide column connected to the base and a carriage assembly connected to the guide for movement relative to the guide between a first raised position and a second lowered position. Novel features of the invention include the provision of a helical drive screw which drives a jar lid engaging assembly and a novel safety clutch mechanism which prevents the exertion of excessive force on the jar being opened.

A programmable finite state machine (FSM) includes, in part, a first address calculation logic block, a first lookup table, a second address calculation logic block, and a second lookup table. The first address calculation logic block generates an address for the first lookup table based on the received input symbol and the current state. The data stored in first look-up table at the generated address is used by the second address calculation logic block to compute an address for the second lookup table. Data stored in the second lookup table is the next state to which the FSM transitions. The programmable FSMs uses redundant information of the transition table to compress these transitions and thus requires a smaller memory while maintaining a high data throughput. The data in the first and second lookup tables are coded and supplied by a compiler. The FSM operation may optionally be pipelined.

Methods and compositions are disclosed for the reduction of immune responses to an exogenous allergen. The reduction is obtained by pre-treatment or pre-conditioning, without injection, of a subject with the allergen so as to reduce immune responses in the subject upon additional exposure to the allergen. The invention is advantageously used in a variety of contexts, including seasonal allergies wherein pre-treatment or pre-conditioning is performed before the onset of the seasonal allergy.

The present invention provides a method for locating mobile units in a wireless telecommunication network. The method includes determining at least one distance associated with a mobile unit in communication with at least one base station in a wireless telecommunications network, determining a first location based on said at least one distance, and selecting a plurality of second locations based on the first location. The method also includes determining a plurality of likelihoods that the mobile unit is at each of the plurality of second locations.
摘要:
A method and apparatus for transforming regular expressions into a less resource intensive representation is disclosed. The method and apparatus converts a collection of regular expressions into a multi-level representation in which the memory requirements of the lowest level representation is reduced when compared with a conventional finite state automaton representation. The method and apparatus converts a collection of regular expressions into a collection of segments and a higher level representation in a way that retains the semantics of the original set of regular expressions. This transformation is performed through the use of an intermediate form. The resulting representation and collection admit an implementation which avoids the potentially costly memory requirements of a traditional implementation of the original expressions.

The invention provides a multi-inlet sampling device for an ion source. In general, the sampling device contains at least two sample inlet capillaries and a single outlet capillary that are all fluidically connected. A mass spectrometer ion source and a mass spectrometer system containing the multi-inlet sampling device are also provided. The device is readily removed and installed at ambient pressure without venting the mass spectrometer. Also provided by the invention are methods for simultaneously introducing at least two samples into a mass analyzer.
摘要:
The states associated with a programmable state machine are reordered to compress the storage of transitions which define the state machine. To reorder the states, a score is computed and assigned to each of the states. Next, the states are sorted according to their computed scores. In some embodiments, to compute the score for each current state based on the received input symbol, the number of times that the input symbol causes transition to similar states is added. The sum of the scores in each row of the table is representative of the score for the associated current state associated with that row. The states are sorted according to their score and a new state transition table is generated in accordance with the reordered states.
