摘要:
A surface acoustic wave (“SAW”) sensor system comprises a signal generating part, which applies an electrical signal to a SAW sensor, the SAW sensor connected to the signal generating part, which converts the electrical signal into a SAW, senses a measurement target using the SAW, and converts a SAW output corresponding to the measurement target into an electrical signal, and a signal measuring part connected to one side of the SAW sensor, which detects a change in the electrical signal by time-gating a multiple-transit-echo wave.
摘要:
Provided are a capsule endoscopy system, a medical system, and an operation method of the medical system. A control device outside a human body and two or more implantable medical devices (e.g. capsule endoscopes) form a network with each other, and the two or more implantable medical devices divisionally perform investigation, identification, and treatment while cooperating with each other, by controlling the control device outside the human body.
摘要:
Provided are an automatic gain control (AGC) apparatus using an efficient receiving structure of an impulse signal-based ultra wideband wireless communication system, and a method thereof. An AGC apparatus of an impulse signal-based wireless communication system guarantees an SNR received through an analog circuit unit, outputs correlation values with respect to an impulse preamble of the received signal, outputs the maximum value of the correlation values for each symbol among the correlation values, or divides a symbol period into a plurality of groups and obtains average values through a sum of each group to output the maximum value thereof.
摘要:
A method of increasing 3-HP production efficiency by inhibiting expression of a lactate dehydrogenase, a phosphotransacetylase, and an alcohol dehydrogenase in production of 3-HP using a malonic semialdehyde reduction pathway to prevent metabolite leak and increase a malonyl-CoA pool is disclosed.
摘要:
Provided is a fast charging apparatus and method for a vehicle that may simultaneously charge a battery of a vehicle with electricity from at least two chargers through at least two charge connecting units provided to the vehicle.
摘要:
A modified microorganism having enhanced xylose utilization, an expression vector for constructing the modified microorganism, and a method of producing a chemical using the same are disclosed.
摘要:
A method of simultaneously producing 3-hydroxypropionic acid (3-HP) and 1,3-propanediol (1,3-PDO) using a microorganism is provided. The method includes converting glycerol into 3-HP and 1,3-PDO using a recombinant microorganism having both 3-HP and 1,3-PDO producing genes.
摘要:
A modulation device uses two base signal axes including a cosine function and two base signal axes including a sine function to modulate bit information and generate a modulation symbol. Accordingly, the frequency efficiency characteristic is improved while maintaining a great power efficiency characteristic.
摘要:
Disclosed is a method for modulating and demodulating data. The method composes symbols by grouping a plurality of symbols for pulse position modulation to newly add symbol compositions to fixed symbols used for the pulse position modulation of the related art. Further, the method uses grouped symbols to improve data transmission rate as the average amount of information increases.
摘要:
A modified microorganism for high efficient production of lactic acid, an expression vector for constructing the modified microorganism, and a method of producing a lactic acid using the same are disclosed. The modified microorganism may produce lactic acid at a high level under acid conditions.
