Preventive terminal device and internet system from drowsy and distracted driving on motorways using facial recognition technology

A drowsy driving prevention apparatus employing a facial recognition technology and a drowsy driving prevention system employing the same is provided. A GPS and a communication unit for informing a central control center or a traffic accident prevention management institute of information about a drowsy driving state and the position of a vehicle are mounted in the drowsy driving prevention apparatus. Thus, traffic accidents can be prevented. A management server is informed of a driver's drowsiness and a driver can access a portable telephone of an external helper over a network using wireless Internet communication technologies, such as Wibro (also called Mobile WiMAX), HSDPA & HSUPA, Long Term Evolution (LTE), Ultra Mobile Broadband (UMB), TD-SCDMA, TRS, GPRS GSM and CDMA. It is therefore possible to prevent traffic accidents caused by drowsy driving in synthetic and multidimensional ways.

Home-monitoring system

A method and system for securing neighborhoods against crime. In one system, a short range wireless LAN technology, e.g., WiFi or WiMax, is employed to relay sensor information, including that from cameras, in real-time to a security server in a neighbor's house, which can significantly improve response time. The wireless LAN technology allows higher quality video to be captured by the on-site cameras, and relayed off-site in real-time, preserving the integrity of the data even if a burglar or intruder finds and destroys or steals the on-site security equipment. Modern IP monitoring may be employed to offer additional capabilities and reliability in these systems.

Method and System for Minimizing Power Consumption in a Communication System

A method and system for minimizing power consumption in a communication system is provided. The method may include adjusting the supply voltage of pre-driver for a power amplifier, which may be used for amplifying a RF signal, in proportion to the envelope of the baseband of the RF signal. The signals may correspond to a variety of communication protocols. For example, WCDMA, HSDPA, HSUDPA, GSM, GPRS, EDGE, WiMAX, OFDM, UWB, ZigBee, and BlueTooth. The signal may be delayed by a number of samples before being input into the pre-driver. The envelope may be measured by evaluating a plurality of I and Q samples from the signal. The number of samples may be calculated by measuring the intermodulation distortion at the output of the amplifier. The supply voltage may be generated by a switching regulator. The method may also include adjusting a supply voltage and bias voltage for a power amplifier in proportion to said envelope of said signal.

Method and apparatus for coexistence

A method for coexistence of an orthogonal frequency division multiple access (OFDMA) receiver (117) such as a WiMAX receiver with a synchronous frame-based transmitter (115) such as a Bluetooth transmitter within a mobile station (110) receives an estimated media access protocol (MAP′) signal indicating when a MAP message is expected to be received by the OFDMA receiver (117) and uses it at a Bluetooth shutdown signal (190) at least when a MAP message is expected to be received. The MAP′ signal can be taken directly from the ODFMA transceiver (117) or it may be produced through analysis of a receiver-enable (RXE) signal that includes not only MAP symbols but also downlink data symbols. The RXE signal can be analyzed using interrupt-and-timer, Fast Fourier Transform, covariance, and / or delay-locked loop techniques to extract historical MAP symbol information and generate expected MAP symbol information. Shutting down a Bluetooth transmitter during expected MAP message receipt permits the OFDMA receiver to maintain synchronicity with an access point while not requiring the Bluetooth transmitter to shut down every time the OFDMA receiver expects to receive an OFDMA symbol.

Method and System for Collaborative Coexistence of Bluetooth and WIMAX

Methods and systems for collaborative coexistence of Bluetooth and WiMax are disclosed. Aspects of one method may include a packet traffic arbiter (PTA) in a mobile terminal that arbitrates among requests to transmit from one or more communication devices collocated in the mobile terminal. The communication devices may comprise, for example, a WLAN communication device, a WiMax communication device, and / or a Bluetooth communication device. The arbitration may be based on, for example, whether a packet will be received by one of the plurality of collocated communication devices at a time of transmission of the present data packet and / or a priority for data to be transmitted. An exemplary scenario may be where a Bluetooth headset may be used for communication over a WiMax voice connection. One arbitration method may comprise allowing the WiMax packet to be transmitted, and replacing the received Bluetooth packet with data indicating silence. Another method may comprise not allowing transmission of the present WiMax packet. Rather, the present WiMax packet and a subsequent WiMax packet may e transmitted at the next transmission period.
