Abstract: A green diode laser includes a tubular laser casing, a heat sink sealedly mounted at the laser casing, a semiconductor chip supported by the heat sink, an optical resonant cavity supported within the laser casing, including a lasing medium and an intracavity frequency doubler, an IR blocking filter inclinedly and seadedly mounted at the laser casing to optically communicate with an output facet, and a photodiode supported within the laser casing at a position that when the laser beam exits the output facet, the IR blocking filter reflects a portion of the laser beam towards the photodiode such that the photodiode is adapted for detecting the laser beam from the IR blocking filter as a feedback for controlling a power output of the green laser chip.

Abstract: It has now been found that in some transmitter implementations which transmit multiple code channels, for example CDMA transmitters, the observed power for each code channel at the output relative to the other code channels is dependent upon the total transmit power due to non-linearities in the transmitter. Methods and apparatus are provided which use pre-set digital gains or digital gain adjustments to compensate for the non-linearities as a function of total transmit power such that at the output, the desired relative powers are observed.

Abstract: In instant communications over a wireless network, a user from a private organization sends the request for instant communications communication through a private server controlled by the private organization. The private server sets up a private account with the wireless carrier and the user communicates via the private account.

Abstract: An apparatus and method of controlling unsolicited traffic are disclosed herein. The apparatus and method can be applied to wireless communication networks such as CDMA2000, UMTS, GPRS and the like so that traffic which is not solicited by wireless communication devices operating on those networks is not sent over the air needlessly. The present application provides techniques to block unsolicited traffic based on the identity of a user (for example based on International Mobile Station Identity (IMSI), Network Access Identifier (NAI), Mobile Station Internet Services Digital Network Number (MSISDN), Session Initiation Protocol (SIP) Universal Resource Locator (url)) as opposed to techniques that are based on a session or IP address, such as a traditional firewall. In accordance to this application, user identity based techniques are applied to block unsolicited traffic whenever a user has established a data session.

Abstract: Methods and apparatus for selecting a wireless communication network based on quality of service criteria associated with an application are disclosed. In one illustrative example, one of several different software applications of a mobile communication device is executed. The software application may be, for example, an e-mail application, an Internet data application, a voice-over-IP application, a video player application, an audio player application, or a video game application. Each software application is associated with different quality of service (QoS) criteria for data communications through a wireless network. The quality of service criteria may include, for example, a bandwidth criterion, a delay criterion, a delay variation criterion, and a data loss criterion. A scanning operation is performed to identify a plurality of a wireless networks available in a coverage area of the mobile device.

The method further comprises sending status information to a packet data serving node that stores a list of push servers associated with a wireless device, and having the packet data serving node forward the status information to the push server. The system and method further includes selectively starting and stopping the serving of the wireless device by the push server during a voice call.

Abstract: A method and system of controlling transmit power of a forward link signal between a basestation and a mobile device in a communications network, the method comprising the steps of: sending a first signal from the basestation to the mobile device, the first signal having a first signal transmit power; receiving the first signal at the mobile device; measuring the first signal for a received signal to noise ratio at the mobile device; sending a second signal from the mobile device to the basestation, the second signal containing information about the received signal to noise ratio; and setting the transmit power of the forward link signal based on the received signal to noise ratio information and the first signal transmit power, whereby if the received signal to noise ratio is high the setting step sets the transmit power of the forward link signal lower, and if the received signal to noise ratio is low the setting step sets the transmit power of the forward link signal higher.

A data rate and signal format indicator signal corresponding to the transmitted signal, and a desired reference power signal are fed to a mapper that outputs a calibration value based on the desired reference power level at the antenna. The calibration value controls the power amplifier gain characteristics in real time.

Abstract: A method of determining the actual transmission rate in a variable transmission rate communication system is provided, using error detection metrics. The received symbols are decoded assuming each possible rate, and then re-encoded to determine a symbol error rate for each possible rate. The possible transmission rates are then narrowed down using a simple measure of the likelihood of error, such as the CRC status determined for each rate. The symbol error rates are compared to either make a confident decision as to the actual transmission rate or to erase the frame. Rather than compare the values of the symbol error rates with predetermined thresholds, the method compares the differences between the symbol error rates for each possible rate with predetermined thresholds. This results in fewer erasures, even if the symbol error rates are low due to high signal to noise ratios.

The QWERTY style keyboard has a plurality of letter keys, wherein each letter key is configured to generate a unique input signal. The processor is coupled to the keyboard and is configured to convert each unique input signal generated by the letter keys into a character code and/or a telephony tone signal. The keyboard mode control software module operates on the processor, and controls whether the processor converts the unique input signals from the letter keys into character codes or telephony tone signals.
