Abstract: A simulator for providing a user with a simulated burning log display providing moving patterns of light which simulate a flickering flame image. The flame image is generated by rotating a shaft with a helically wound light array such that the lights reflect off a mirror with flame shaped reflecting areas onto a partially transparent screen to give the impression to a viewer of flickering flames appearing on a front side of the screen and behind a non-burning pile of logs. The logs have flame colored light transmissive regions which are illuminated by an array of ember LED's under the control of circuitry which generates apparently randomly varying illumination levels, to thereby create a glowing ember effect.

Abstract: An automatic configuration system and method is provided. A detecting unit is used to detect whether a signal indicating link establishment appears at a first connector or a second connector, which serves as a receiving terminal of a node device, and accordingly generate a detecting result. Thus, according to the detecting result, an automatic configuration control unit controls a switching unit to execute a corresponding switching operation and sequentially configure the first connector and the second connector, so as to ensure that data can be transmitted and received reliably in the communication network and to save power.

Abstract: An automatic configuration system for automatically configuring a connecting interface of a node device in a network is provided. The connecting interface of the node device includes a first pair of connectors and a second pair of connectors. The automatic configuration system includes a switching unit, a first analog circuit unit, a second analog circuit unit and a detecting unit. The detecting unit is used to detect whether a first computed result or a second computed result outputted from the first analog circuit unit or the second analog circuit unit involves signals transmitted from another node device in the network, and accordingly generate a detected result to allow the switching unit to execute a switching operation and selectively connect the transmitting unit to the first or second pair of connectors, so as to ensure that data can be transmitted or received reliably in the network.

Abstract: An active hybrid circuit for a full duplex channel generates a duplicated voltage at the current output stage to reduce the energy of the transmitter transmitted to the receiver. The active hybrid circuit cancels the energy of the transmitter transmitted to the receiver when it is operated in a full duplex channel with high-speed transmission. The active hybrid circuit for full a duplex channel comprises a transmit digital-to-analog converter for generating an analog transmit signal, a receive analog-to-digital converter for receiving an analog receive signal, a duplicated voltage digital-to-analog converter for generating a corresponding duplicated voltage according to the analog transmit signal of the transmit digital-to-analog converter, and a plurality of signal combiners for subtracting the duplicated voltage from the analog transmit signal to cancel the influence of analog transmit signal to the analog receive signal.

Abstract: A data transmission device is applied to a network apparatus having an automatic crossover function, and is connected to a transmission control unit, such that the transmission control unit detects an operating status of the network apparatus and accordingly generates a control command. Thereby, a current source generating unit provides current sources to a first-mode converting unit and a second-mode converting unit according to the control command. This allows a suitable data transmission processing mode to be selected automatically and instantaneously for the operating status of the network apparatus by the current sources from the current source generating unit and the control command generated from the transmission control unit, so as to achieve power saving, low distortion and/or anti-interference.

Abstract: A receiver with baseline wander compensation is applicable to a digital communication system. The receiver includes an Analog-to-Digital Converter (ADC), a slicer, a threshold value detector, a gain controller, a baseline wander compensator, a delay circuit, an analog gain stage, and a digital gain stage. The baseline wander compensator is used to perform an operation and a filtering process on a voltage obtained prior to processing by the slicer and a voltage after the processing so as to obtain a baseline wander voltage value for compensation and control. The threshold value detector and the gain controller dynamically produce control signals of analog gain and digital gain. The analog gain stage compensates degrading of communication signals passing through transmission channels in an analog gain manner. The delay circuit is used to compensate the delay of the conversion performed by the ADC. The digital gain stage compensates insufficiency of the analog gain.

Abstract: A data processing system and method are provided. A first combination logical encoding unit encodes a first set of encryption data to create digital symbols and outputs the digital symbols to an analog/digital symbol processing unit. Further, a combination logical decoding unit performs logical operations to transform a first set of multi-dimensional digital symbols converted from multi-dimensional analog symbols received from a network via the analog/digital symbol processing unit to create a second set of encryption data. Then, the analog/digital symbol processing unit outputs the second encryption data to a second combination logical encoding unit where the second set of encryption data is encoded to create a second set of multi-dimensional digital symbols. A comparing unit then compares the first and second sets of multi-dimensional digital symbols to determine the validity of the first set.

Abstract: Timing recovery method and device for combining pre-filtering and feed-forward equalizer functions are proposed and used in a digital communication system. A signal receiver is provided to receive a signal transmitted from a signal transmitter in the communication system, and recovers a sampling clock phase of the received signal to the phase of the signal transmitted from the signal transmitter. The method is used to control the signal receiver to transform the received signal to a signal similar to a Nyquist pulse after the pre-filtering and feed-forward equalizing operations are performed on the received signal, thereby improving the performance of the following sampling timing recovery process and increasing the signal noise ratio (SNR) of the received signal.

Abstract: The invention is a holder-filter for tobacco products such as cigarettes. The filter removes tarry materials present in combustion products as aerosol droplets or vapors by passing the combustion products through a restricted passage to impinge on a cool surface of an annular sealed chamber formed between two o-rings, to change direction of the combustion products and expand them into the annular sealed chamber such that the tarry materials congeal on the surfaces of the annular sealed chamber.
