摘要： An auto-releasing method and arrangement of a detachable magazine for a firearm is provided. The auto-releasing arrangement is able to physically remind the operator that it is the right time to replace the magazine and to continue fire without having to performing a series of magazine reloading operations to reset the firearm into the fire mode, wherein the magazine will automatically be released and removed from the magazine receiving cavity of the firearm. In other words, the operator can simply insert another loaded magazine into the magazine receiving cavity while the firearm still has at least one cartridge chambered for firing, so that the time cost on performing such operations can substantially be saved to increase the survival probability during a gunfight or the like.

摘要： A device receives network information from an analyzer device associated with a host device, a target device, and a link of a network, and compares the network information and historical equalizer calibration information to identify a set of equalizer calibration information. The historical equalizer calibration information is associated with multiple host devices, multiple target devices, and multiple links. The device ranks the set of equalizer calibration information, based on quality information associated with the historical equalizer calibration information, to generate a ranked set of equalizer calibration information. The device provides the ranked set of equalizer calibration information to the analyzer device to permit the analyzer device to identify selected equalizer calibration information of the ranked set of equalizer calibration information, and utilize the selected equalizer calibration information.

摘要： An apparatus and method for ultra wideband (UWB) communication, using a dual band pass filter (BPF) is disclosed. The UWB communication apparatus may include a first BPF performing a first band pass filtering with respect to a UWB signal, a second BPF that has a center frequency differing from a center frequency of the first BPF, and performs a second band pass filtering with respect to the UWB signal, a first envelope detector that detects a size of a first signal filtered in the first BPF, a second envelope detector that detects a size of a second signal filtered in the second BPF, and a demodulator that demodulates a UWB signal, using the size of the first signal and the size of the second signal.
