A protocol conversion and arbitration circuit may include: a protocol conversion circuit to receive signals complying with a second protocol used by a master, and to convert the received signals into signals complying with an intermediary protocol used by an internal bus of a slave; and a transform circuit to receive, from the protocol conversion circuit, and to convert the once-converted signals into signals complying with a first protocol used by the slave.

A micro switch having a dielectric layer having a movement region formed on a substrate, a conductive layer formed on a predetermined portion of the movement region, a dielectric film formed on the conductive layer, first and second electric conductors formed a predetermined distance above the dielectric film, one or two lower electrodes formed on the movement region, and one or two upper electrodes formed a predetermined distance above the two lower electrodes, the one or two upper electrodes moving the conductive layer and the dielectric film upwards when an electrostatic force occurs between the upper and lower electrodes, and capacitively coupled with the first and second electric conductors to allow a current to flow between the first and second electric conductors. Such a micro switch has a high on/off ratio and isolation degree and a simple structure, and can be fabricated in a very easy process.

An RF power sensor for measuring power for an RF signal using capacitance includes a substrate preferably formed of a semiconductor, such as silicon or of a dielectric substance, a fixture part fixed to the substrate and forming a signal line and ground lines that transmit RF signals, and a bridge connected to the ground lines and floating over the signal line, wherein the bridge is driven by an external driving force, and the external driving force induces capacitance between the bridge and the signal line. Accordingly, power for an RF signal can be measured through the capacitance between the signal line and the bridge. The RF power sensor facilitates matchings, reduces insertion loss, and can be used in a wide bandwidth because it is based on transmission lines having characteristic impedance. Further, high power can be measured depending upon bridge designs.

An information search method and apparatus employ an Inverse Hidden Markov Model (IHMM) for stochastically searching for a reference information model among a plurality of predetermined reference information models obtained by training that best matches unknown information which is expressed by a Hidden Markov Model (HMM) chain. The method and apparatus find an optimal path in a HMM state lattice using a minimum unlikelihood score, rather than a maximum likelihood score, and using a Viterbi algorithm, to recognize unknown information, so that unnecessary computations are avoided. The method and apparatus can be used for finding the most likely path through a vocabulary network for a given utterance.

A differential type VCO (Voltage Controllable Oscillator) is disclosed. The VCO has a differential amplifier having a couple of transistors and a couple of LC tanks. At each LC tank, a transformer is connected to form a buffer. An oscillating signal is output through the buffer with no power consumption. Additionally, a capacitor is connected to the secondary coil of the transformer to form a bandpass filter, thereby attenuating a harmonic signal included in the oscillating signal.
