    Abstract: A backplane for at least one electrical module (100) and a method of replacing a fuse for an electrical module (100). The electrical module (100) comprises a circuit board (101) comprising a power input port (1011) for inputting electric power to at least power and/or electrically drive an external device coupled to the electrical module (100), a fuse holder (102) electrically coupled to the power input port (1011) and adapted to receive a fuse (104), a fuse detecting circuit (103) arranged on the circuit board (101) and electrically coupled to the fuse (104) via the fuse holder (102) to detect a status of the fuse (104), and an output port (1012) arranged on the circuit board (101) and coupled to the fuse detecting circuit (103) to at least output detecting signals about the status of the fuse (104) to a controller. The fuse (104) can be replaced more easily and safely. Furthermore, when a fuse (104) of an electrical module (100) is needed to be replaced, it is no longer necessary to break the power supply to the entire backplane, but it is only necessary to unplug the corresponding electrical module to replace the blown fuse. In this way, economic losses and maintenance costs are further reduced.

    Abstract: Embodiments include methods for managing a communication link between the wireless device and a transfer control protocol (TCP) peer device. Some methods may include establishing a TCP flow between a wireless device modem and the TCP peer device, and managing the TCP flow by an offload device of the wireless device when the modem is in a low power mode of operation. Some methods include sending from the offload device to the modem an update message including TCP flow activity that occurred related to the TCP flow while the modem was in the low power mode of operation when the modem transitions to an active operation mode. Some methods include establishing a TCP connection between the offload device and the modem using a source internet protocol address and a TCP port associated with the TCP peer device, and forwarding to the modem TCP flow activity with the TCP peer device.

    Abstract: Provided are methods, apparatuses, and computer-readable medium for automatic tamper detection that are both robust and low in complexity. The described methods can detect many different tamper types while also reducing false positives. In various implementations, the described methods include comparing an input frame against a background picture, using tiles of pixels taken from both the input frame and the background picture. When enough differences are detected between the tiles of pixels from the input frame and the tiles of pixels from the background picture, tamper is suspected. When tamper is suspected, further checking of the frame may be enabled, including checking for blur and/or checking a downsampled version of the whole frame. The additional checks can confirm that an actual tamper of the camera has occurred.

    Abstract: A first communication device associated with a first communication network determines that a second communication device associated with a second communication network is located proximate to the first communication device. The first communication device generates a data unit that includes information indicating i) a color identifier of the second communication network, the color identifier usable to identify transmissions from the second communication network, and ii) that a dynamic clear channel assessment (CCA) procedure should not be used for transmissions from the second communication network. The first communication device transmits the data unit to at least one other communication device associated with the first communication network such that the at least one other communication device associated with the first communication network does not use the dynamic CCA procedure for transmissions identified as being from the second communication network.

    Abstract: A first communication device generates a first physical layer (PHY) data unit that includes information indicating a capability to use a channel bandwidth greater than a maximum channel bandwidth of the first communication device, and transmits the first PHY data unit to a second communication device during an association process with the second communication device. The first communication device generates a second PHY data unit that includes information indicating a capability to use at most the maximum channel bandwidth of the first communication device, and transmits the second PHY data unit to the second communication device when the first communication device is associated with the second communication device.
