Upon receiving an acknowledgement after retransmission of a data segment, an acknowledgement number contained in the acknowledgement is compared with an acknowledgment number expected to be contained in an acknowledgement pertaining to the retransmitted data segment. When the former is larger than the latter, it is determined that the acknowledgement pertains to a data segment that was originally transmitted.

An apparatus includes a semiconductor layer, a dielectric layer, and a light prevention structure. The semiconductor layer has a front surface and a backside surface. The semiconductor layer includes a light sensing element and a periphery circuit region containing a light emitting element and not containing the light sensing element. The dielectric layer contacts at least a portion of the backside surface of the semiconductor layer. At least a portion of the light prevention structure is disposed between the light sensing element and the light emitting element. The light prevention structure is positioned to prevent light emitted by the light emitting element from reaching the light sensing element.

The invention discloses a protection circuit and a method and device for controlling the same, and aims to prevent voltage disturbance from influencing functions of electronic devices when a battery is put into a battery compartment, and improve the safety performance of the battery. The control circuit comprises a first switch, a second switch, a first resistor and a time delay circuit, wherein when a battery pack enters a working state, the first switch is closed to ensure that a grid electrode of the second switch obtains a critical voltage of a closed state and then enters the closed state after the current output by a cell passes through the time delay circuit and after a preset delay time; an anode of the cell is conducted with an anode of the battery pack, so that the voltage disturbance is prevented from influencing the functions of the electronic devices when a battery is put into a battery compartment; and when the battery pack is not in the working state, the first switch is turned off, the voltage of the grid electrode of the second switch is reduced to the critical voltage when the second switch enters the closed state, then the second switch enters a turned-off state, and the current output by the anode of the cell is turned off, so that the safety performance of the battery when the battery is not put into the battery compartment is improved.

The present invention discloses an ultraviolet radiation generating system and method for treating a coating on a substrate, such as a coating on an optical fiber cable. The system includes a microwave chamber having one or more access channels that allow substrates to move within, or through, the processing volume of the microwave chamber. A microwave generator is connected to the microwave chamber to excite a longitudinally extending plasma lamp installed in the processing space of the microwave chamber. The plasma lamp emits ultraviolet radiation to irradiate the substrate in the treatment volume. A reflector is installed in the processing space of the microwave chamber and is capable of reflecting the ultraviolet radiation to uniformly irradiate the substrate in a circumscribed manner. When the system is in operation, the microwave chamber is substantially sealed from the emission of microwave energy and ultraviolet radiation.

The application relates to a head lamp for a vehicle and a controlling method thereof. The headlamp for a vehicle includes a low beam source having a plurality of low beam elements arranged in a designated matrix; a high beam source having a plurality of high beam elements arranged in a designated matrix; and a control unit configured to generate a darkness area or light area by selectively turning on / off the high beam elements and the low beam element based on a designated matrix beam pattern, according to whether a target is detected.
