摘要:
A device and method for detecting and suppressing double-talk in a cellular mobile unit employ a cellular transceiver; a receive signal path; a transmit signal path; and a double-talk detector. The double-talk detector determines a receive slope of a receive signal, and determines a transmit slope of a transmit signal. The double-talk detector further determines a difference slope of a difference signal that is determined by evaluating differences between the receive signal and the transmit signal. Finally, the double-talk detector generates a double-talk flag signal in the event the transmit slope indicates an increasing transmit speech power, and the receive slope and the difference slope indicate a prescribed relationship between the changes in the receive speech power and the difference power.

A semiconductor device with improved transistor operating and flicker noise characteristics includes a substrate, an analog NMOS transistor and a compressively-strained-channel analog PMOS transistor disposed on the substrate. The device also includes a first etch stop liner (ESL) and a second ESL which respectively cover the NMOS transistor and the PMOS transistor. The relative measurement of flicker noise power of the NMOS and PMOS transistors to flicker noise power of reference unstrained-channel analog NMOS and PMOS transistors at a frequency of 500 Hz is less than 1.

A semiconductor device includes a gate insulator and a gate electrode stacked on a substrate, a source/drain pattern which fills a recess region formed at opposite sides adjacent to the gate electrode, the source/drain pattern being made of silicon-germanium doped with dopants and a metal germanosilicide layer disposed on the source/drain pattern. The metal germanosilicide layer is electrically connected to the source/drain pattern. Moreover, a proportion of germanium amount to the sum of the germanium amount and silicon amount in the metal germanosilicide layer is lower than that of germanium amount to the sum of the germanium amount and silicon amount in the source/drain pattern.

A catheter imaging probe for a patient. The probe includes a conduit through with energy is transmitted. The probe includes a first portion through which the conduit extends. The probe includes a second portion which rotates relative to the conduit to redirect the energy from the conduit. A method for imaging a patient. The method includes the steps of inserting a catheter into the patient. There is the step of rotating a second portion of the catheter relative to a conduit extending through a first portion of the catheter, which redirects the energy transmitted through the conduit to the patient and receives the energy reflected back to the second portion from the patient and redirects the reflected energy to the conduit.
