Abstract: An apparatus for driver assistance includes a radar installed to a vehicle, having a sensing area outside the vehicle, and configured to provide object data, and a controller configured to identify a distance to an object from the vehicle and a moving speed of the object based on the object data. The radar includes an antenna array, a signal processing circuit configured to provide a transmission signal to the antenna array to transmit radio waves and acquire a reception signal corresponding to radio waves received by the antenna array, and a signal processor configured to control the signal processing circuit to provide a pre-chirp signal including a plurality of pre-chirps and a main chirp signal including a plurality of main chirps to the antenna array. The number of pre-chirps is less than the number of main chirps.

Abstract: A semiconductor device includes: an active pattern on a substrate, wherein the active pattern includes a plurality of channel layers stacked on one another; a plurality of source/drain patterns spaced apart from each other in a first direction and disposed on the active pattern, wherein the plurality of source/drain patterns are connected to each other through the plurality of channel layers; and first and second gate electrodes at least partially surrounding the channel layers and extending in a second direction, wherein the second direction intersects the first direction, wherein the active pattern has a first sidewall and a second sidewall that faces the first sidewall, and wherein a first distance between the first sidewall of the active pattern and an outer sidewall of the first gate electrode is different from a second distance between the second sidewall of the active pattern and an outer sidewall of the second gate electrode.

Abstract: A device for providing guidelines for cardiopulmonary resuscitation (CPR) includes an input unit operable to receive a gender information of a CPR provider; a. processing unit operable to process the gender information of the CPR provider; and an output unit operable to provide an output. If the gender information of the CPR provider is male, the output unit provides an instruction to the CPR provider to place an end of heel of his hand over a distal end of a sternum during chest compressions. In addition, if the gender information of the CPR provider is female, the output unit provides another instruction to the CPR provider to place an end of heel of her hand approximately 1.5˜2.0 cm above a distal end of a sternum during chest. compressions.
