Abstract:
A protection circuit, applied to a flash memory including a power supply pin, includes a capacitor and a switch. A power supply provides a reference voltage. The capacitor is electrically connected to the power supply pin and a ground point. The switch is electrically connected between the power supply pin and the power supply. When the reference voltage is higher than a threshold voltage, the switch is turned on, such that the reference voltage is inputted into the power pin via the switch. When the reference voltage is lower than the threshold voltage, the switch is turned off.

Abstract:
A handheld electronic apparatus includes a positioning module, a sensing module, a constellation database, and a processing module. The positioning module generates location information associated with the handheld electronic apparatus according to a satellite signal received by the handheld electronic apparatus. The sensing module detects a vertical tilted angle and a horizontal observing direction associated with a positioned state of the handheld electronic apparatus. The processing module retrieves corresponding real-time constellation information from constellation data stored in the constellation database according to timing information, the location information, the vertical tilted angle, and the horizontal observing direction.

Abstract:
A network device (20) for connecting an Ethernet terminal device (10) to a communication network (30) includes a database (23), a first transceiving module (21), a second transceiving module (26), and a destination address determining module (25). The database is used for saving a reference address. The first transceiving module is connected to the Ethernet terminal device. The second transceiving module is connected to the communication network, and is used for receiving a packet sent by the communication network and forwarding the packet. The destination address determining module is used for determining whether a destination address of the packet matches with the reference address saved in the database. If the destination address of the packet matches with the reference address saved in the database, the first transceiving module sends the packet to the Ethernet terminal device.

Abstract:
A network communication device includes a protection value optimizing module, a rate calculating module, a rate determining module, and a connection module. The protection value optimizing module is configured for optimizing an impulse noise protection (INP) value. The rate calculating module is configured for calculating a first downlink rate based on an initial INP value and calculating a second downlink rate based on an optimized INP value. The rate determining module is configured for determining if the first downlink rate and the second downlink rate are greater than a maximum downlink rate provided by the central office device. The connection module is configured for establishing a communication connection between a terminal device and a central office device according to the second downlink rate and the optimized INP value upon the condition that the second downlink rate is not greater than the maximum downlink rate.
