A method and system for extracting feature utilizing an AHaH module (Anti-Hebbian and Hebbian). A sparse input data stream can be presented to a synaptic matrix of a collection of AHaH nodes associated with the AHaH module. The AHaH module operates an AHaH plasticity rule via an evaluate phase and a feedback phase cycle. A bias input line can be modulated such that a bias weight do not receive a Hebbian portion of the weight update during the feedback phase in order to prevent occupation of a null state. The input space can be bifurcated when the AHaH nodes fall randomly into an attractor state. The output of the AHaH module that forms a stable bit pattern can then be provided as an input to a content-addressable memory for generating a maximally efficient binary label.

A push-pull driver for powering fluorescent lamps in a backlight system includes a transformer with three primary windings to realize the advantages of both a push-pull switching topology and a full-bridge switching topology. The first and the second primary windings alternately conduct currents in opposite polarities to generate an alternating current signal to power one or more lamps coupled to a secondary winding of the transformer. The third primary winding is short-circuited to preserve energy stored in the transformer in a null state when both the first and the second primary windings are not conducting.

There is disclosed a self-timed processor. The self-timed processor includes a plurality of functional blocks comprising null convention logic. Each of the functional blocks outputs one or more multi-rail data values. A global acknowledge tree generates a global acknowledge signal provided to all of the plurality of functional blocks. The global acknowledge signal switches to a first state when all of the multi-rail data values output from the plurality of functional blocks are in respective valid states, and the global acknowledge signal switches to a second state when all of the multi-rail data values output from the plurality of functional blocks are in a null state.

The invention discloses a double-interface encryption memory card with a USB (universal serial bus) interface and a RFID (radio-frequency identification) interface, and a management method and system of data in the double-interface encryption memory card. The management method comprises the steps that the USB interface is used for connecting with a PC (personal computer) to carry out data reading / writing, and the RFID interface is used for receiving and sending radio-frequency signal, and receiving a security command from the radio-frequency signal; the data in the card is stored after encryption; in an initialization stage, the double-interface encryption memory card generates a data key and stores the data key; in a use state, the data key in the double-interface encryption memory card is in a null state, when a first radio-frequency reading / writing device is activated in a used area, the data key is in a usable state, and the data key is used for encrypting and decrypting the data and completing the reading / writing operation; and in a destroy stage, when the double-interface encryption memory card enters a destroy area, the destroy command sent by a second radio-frequency reading / writing device is received and executed so as to destroy the stored data key. By the adoption of the scheme disclosed by the invention, the data security and data transmission speed are improved.

A method for abnormally interrupting a call based on TCS includes: 1) sending a connection release request message RELEASE to an incoming side by an outgoing side when encountering an abnormal situation, and changing the state of the outgoing side into a connection release request state RELEASE REQUEST; 2) sending a connection release complete message RELEASE COMPLETE to the outgoing side by the incoming side when receiving the connection release request message, and changing the state of the incoming side into a null state NULL; and 3) changing the state of the outgoing side into a null state after receiving the connection release complete message at the outgoing side. The present invention can effectively improve the error tolerance of both the outgoing side and the incoming side of the voice call.

The invention discloses a voice domain name resolving method for a home gateway. The method comprises the following steps: initializing an array and setting null; creating a domain name system thread; inquiring a state mechanism, judging the state mechanism inquired by a current domain name system, returning if inquiry is running, loading a domain name to be inquired if inquiry is in a null state, comparing with a domain name in a domain name system, judging whether the loaded domain name exists in the domain name system or not, and giving an inquiry failure result if the loaded domain name does not exist in the domain name system; if loaded domain name exists in the domain name system, performing domain name resolving to obtain a corresponding IP (Internet Protocol) address, loading the domain name and a corresponding IP address thereof into a corresponding array, and changing the state mechanism to inquiry success; adding the successfully-inquired domain name and the corresponding IP address thereof into a database of the domain name system. In the method, domain name addresses are resolved by creating a thread, so that waste of resources is reduced effectively, real addresses needing domain name resolving can be obtained rapidly and kept, and high efficiency, high instantaneity and high accuracy are achieved.

The invention discloses a method and device for monitoring high speed shared control channel (HS-SCCH) in a radio communication system. In the invention, current state has to be determined first, and corresponding monitoring process is carried out according to the state determined. wherein the current state is any one of a null state, an active state, a inactive state and a discontinuous receiving state, monitoring is not conducted under the null state, monitoring is conducted under the active state and the inactive state, and the discontinuous monitoring is conducted under the discontinuous receiving state according to discontinuous receiving parameters. According to the invention, the UE power consumption with low on-line requirement for a long time is lowered. On the other hand, frequently starting up an inactive timer is prevented.

The invention belongs to the auxiliary facility of production equipment in metallurgical industry and particularly relates to a failure null transition device for a hot-rolling finishing mill. The transition device comprises an upper mandrel and a lower mandrel, and is characterized in that the upper mandrel is arranged above the lower mandrel; a roller sleeve is respectively sheathed on the uppermandrel and the lower mandrel; the spindle noses of the upper mandrel and the lower mandrel are respectively arranged on a bearing; the bearings are both arranged on bearing pedestals; the bearing pedestal which is provided with the upper mandrel is fixedly installed on a bracket; the bearing pedestal which is provided with the lower mandrel is fixedly arranged on a support; the bracket is fixedly installed on the bearing pedestal which is provided with the lower mandrel, and the upper end of the upper bearing pedestal is provided with an adjusting instrument.
