摘要:
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.

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.

A network device, for forwarding packets from an asynchronous transmit mode (ATM) network over different permanent virtual connections (PVC) to a plurality of terminal devices, includes a storage module, a flag setting module, a buffer, and a sending module. The storage module is for storing an identifier of at least one predetermined PVC, and packets transmitted over the at least one predetermined PVC need to be processed with higher priority. The flag setting module is for receiving the packets transmitted over the different PVCs, marking packets transmitted over the at least one predetermined PVC corresponding to the identifier stored in the storage module, and sending the packets to the buffer for temporarily storing the packets. The sending module is for retrieving the packets from the buffer, and first sending the marked packets to the plurality of terminal devices.

An identification tag information reminder system and a method thereof are provided. The system comprises an identification tag, for storing a tag identification code, an identification condition data and a reminder message corresponding to the identification condition data; and a portable device, comprising a memory, for storing a plurality of predetermined reminder conditions; an identification tag access module, for accessing the tag identification code, the identification condition data and the reminder message corresponding to the identification condition data of the identification tag; a processing module, for comparing the predetermined reminder condition with the tag identification code and the identification condition data to generate a comparison result; and an indicating module, for outputting the reminder message according to the comparison result.
摘要:
The present invention provides a digital television (TV) system and receiver which are capable of providing information of point of interest (POI) associated with programs or advertisements. A transmitting end of the digital TV system adds information of a POI included in a digital AV data into the digital AV data, so as to generate a digital AV signal to be transmitted. A receiving end of the digital TV system includes a digital AV receiver and a display device. The digital AV receiver receives and decodes the digital AV signal to generate the information of the POI. The display device displays the information of the POI.
