Learning infrared amplifier for remote control devices
A learning remote “learns” both a digital code carried by an infrared operational signal as well as a timing characteristic (for example, time period) of a carrier used to modulate the operational signal. When the photodiode of the learning remote is close to the transmitter of the remote to be learned from, a low frequency saturation current is superimposed on the intelligence signal. Rather than using a fixed reference voltage to detect when the carrier component of the intelligence signal transitions, an adaptive reference voltage (VAR) is used. A comparator compares a photocurrent voltage to VAR. Because VAR is maintained between the envelope of positive peaks and the envelope of negative peaks of the photocurrent voltage despite changes in the low frequency current, the comparator detects each transition of the carrier component. A microcontroller timer determines the time between transitions output by the comparator and thereby determines the timing characteristic.

Data collection system and data collection method
The present invention relates to a data collection system and a data collection method in a sensor network, enabling sensor modules to consume lower amounts of power. The base station transmits data collection request signals to one or more sensor modules which are lower than the base station by 1 in a tree structure. Each sensor module which has received the data collection request signal transfers the signal to one or more sensor modules which are lower than the module by 1. The base station regards the transfer of the signal as ACK for the data collection request signal transmitted therefrom to the sensor module which is lower than the base station by 1. The transmission of a data collection acknowledgement signal starts from a sensor module at the low-order end. When a sensor module receives the data collection acknowledgement signal from a downstream sensor module which is lower than the module by 1, the module transmits the signal to an upstream sensor module which is higher than the module by 1. The downstream sensor module regards the transmission of the signal as ACK for the data collection acknowledgement signal transmitted therefrom, and enters standby mode. In this manner, the sensor modules enter standby mode in sequence starting from the sensor module at the low-order end. Thereby, it is possible to achieve reductions in the frequency of signal transmission while maintaining reliable data communication. Thus, each module consumes lower amounts of power.

Source signature deconvolution method
A method of filtering seismic signals is described using the steps of obtaining the seismic signals generated by activating a seismic source and recording signals emanating from the source at one or more receivers; defining a source signature deconvolution filter to filter the seismic signal, wherein the filter is scaled by a frequency-dependent term based on an estimate of the signal-to-noise (S/N) based on the spectral power of a signal common to a suite of angle-dependent far-field signatures normalized by the total spectral power of the signatures within the angular suite and performing a source signature deconvolution using the source signature deconvolution filter.
Semiconductor memory device
A semiconductor memory device comprises an address terminal through which an address for reading out stored data in a memory array is input, a clock input terminal through which an input clock is input, a data output terminal through which data read out from the memory array in accordance with the address is output, and a clock output terminal through which an output clock synchronous with the input clock is output. The clock output terminal invariably outputs one of a first voltage and a second voltage. Only when valid data is output from the data output terminal, the clock output terminal causes an output voltage to go from the first voltage to the second voltage or from one voltage to the other voltage.
Semiconductor memory device having a word line activation circuit and/or a bit line activation circuit and a redundant word line activation circuit and/or a redundant bit line acitvation circuit
A word line activation circuit having a temporary memory circuit for storing word line inactivation information for inactivating a word line of a defective memory cell, and an inactivation address sensing circuit for determining whether or not a redundant memory cell is to be used in accordance with the word line inactivation information and an address specification signal is provided for each of word lines. When the inactivation address sensing circuit determines that the redundant memory cell is to be used, a redundant word line is activated by a redundant word line activation circuit.
