Network discovery in wireless communication systems
Apparatuses may stay synchronized with a network via a beacon signal transmitted at a set interval. Communication-related activities may be planned around instances when beacon signals are expected, which may also be known as a target beacon transmission time (TBTT). Scanning opportunities, which are periods of time during which apparatuses may perform passive scanning, may be planned based on an interfere multiple of a network beacon signal interval. Apparatuses may, upon realizing a scanning opportunity, opt either to utilize the scanning opportunity or to participate in network beaconing. In example scenarios where apparatuses opt to utilize scanning opportunities, apparatuses may prepare a network information message and then enter a passive scanning mode. Apparatuses may remain in the passive scanning mode for the duration of the scanning opportunity, reacting when messages are received from devices outside of the network by transmitting the network information message. |

A method which makes it possible to replace a reference pattern (aka texture) on a video of clothing is described.

Voltage regulator having current and voltage foldback based upon load impedance
The regulated output voltage of a voltage regulator is maintained up to a current limit, Ilimit, then as the load impedance continues to decrease the output current does not increase past the current limit, Ilimit, but rather the output voltage decreases forcing the output current to also decrease to satisfy Ohm's Law: IOUT=VOUT/ZLoad. When the output voltage drops below the regulated voltage value because of current limiting the voltage regulator shifts from a current limit mode to a current foldback mode wherein the output current decreases with the decrease in output voltage until the output current reaches a current foldback minimum, Ifoldback, at an output voltage of substantially zero volts. As the load impedance increases so will the output voltage and current until the output voltage is back at substantially the regulation voltage value, and the output current is less than or equal to the current limit, Ilimit. |
