Method of synchronizing events with a digital television audio-visual program

A method and apparatus for synchronizing an event produced at a digital television receiver with an instant of a transmitted video, audio, or data element of a digital television program is disclosed. In a digital television system, a system time clock generates a timeline that is used to synchronize the presentation of the video, audio, and data elements of the television program. An application time is used in program production to synchronize instants of the several program elements. To synchronize a receiver generated event with an instant of a transmitted video, audio, or data program element, samples of the application time are transmitted to a receiver in a synchronized data service. A reconstructed application time is generated at the receiver as a function of the current system time, the application time sample, and the presentation time stamp of the data access unit in which the application time sample was transmitted. The presentation time of the program instant is associated with an application time correlating the event and the instant. The correlating application time is transmitted to the receiver as part of a synchronous or asynchronous data service and the event is instigated when the reconstructed application time corresponds to the correlating application time. A clock for generating a reconstructed application time synchronized to the system time is also disclosed.

Semiconductor circuit device simulation method and semiconductor circuit device simulator

A simulator for accurately simulating a deterioration amount and a recovery amount of transistor characteristics, by which a semiconductor device can be designed with high reliability, and the method are provided. When a gate voltage of a negative level (a negative bias voltage) “Vg” is applied to a gate of the transistor, characteristics of the transistor are deteriorated. When application of the negative level gate voltage “Vg” is terminated (when applying a bias free voltage), the deteriorated transistor characteristics are recovered. In a deterioration period and a recovery period, a logarithm “log(t)” is obtained for an application time “t” of the gate voltage, a deterioration amount ΔPD(t)=CD+BD·log(t) is calculated by using constants CD and BD depending on the negative bias voltage, a recovery amount ΔPR(t)=CR+BR·log(t) is calculated by using constants CR and BR depending on the bias free voltage, and the deterioration amount (ΔPD), the recovery amount (ΔPR) and a basic deterioration amount (XD) are summed up. Preferably, passage of time is divided, and a deterioration amount and a recovery amount are obtained for each time zone by using different deterioration and recovery functions for each time zone.

Associative memory circuit based on memory resistor

ActiveCN103580668ADigital storageLogic circuitsPaired stimuliMemory circuits
The invention discloses an associative memory circuit based on a memory resistor. The associative memory circuit based on the memory resistor comprises the memory resistor, a first resistor, a second resistor and a calculation comparator. The first resistor and the memory resistor are connected to a first input end of the calculation comparator in series in sequence. A non-series-connection connecting end of the memory resistor serves as a first input end of the associative memory circuit. A series-connection connecting end of the first resistor and the memory resistor serves as a second input end of the associative memory circuit. One end of the second resistor is connected to the first input end of the calculation comparator and the other end of the second resistor is grounded. A second input end of the calculation comparator is used for being connected with reference voltage. The output end of the calculation comparator is used as the output end of the associative memory circuit. The first input end and the second input end of the associative memory circuit are used for receiving conditioned stimulus signals and receiving unconditioned stimulus signals respectively. The output end of the associative memory circuit is used for outputting response signals. By the adoption of the associative memory circuit based on the memory resistor, the forming process and the forgetting process of biological associative memory can be simulated according to the relation between the application time of the conditioned stimulus signals and the application time of the unconditioned stimulus signals.

Tunnel supporting structure across active fault

ActiveCN103485796AOvercoming the problem of timing of applicationConstruction safetyUnderground chambersTunnel liningActive faultFoam concrete
The invention relates to a tunnel supporting structure, and in particular to a tunnel supporting structure across an active fault. The tunnel supporting structure comprises a fault across section and common supporting sections connected with the two ends of the tunnel supporting structure, wherein the common supporting sections adopt combined lining structures; the fault across section is orderly provided with a secondary lining, a foam concrete layer, a primary lining, a first waterproof layer and a preliminary support from inside to outside along the radial direction of the tunnel; the primary support, the first waterproof layer and the primary lining form the combined lining structure. The tunnel supporting structure is capable of overcoming the problem of application time selection, and is safe and convenient to construct. The primary lining is capable of partially bearing stress generated by the fault due to creep; in the meantime, the foam concrete is capable of providing a displacement space and absorbing energy; finally, the secondary lining is used for forming safety stock of the structure and ensuring that the clearance is not affected by fault movement; the tunnel supporting structure is high in safety storage, and has excellent shock resistance and excellent ability of resisting damage caused by fault creep and fault movement.
