Abstract: A method for providing over-heating protection of a target device within an information processing system is disclosed. A determination is made whether or not a power status of the information processing system is set to turn on a main power of a power supply device. If the power status of the information processing system is set to turn on a main power of a power supply device, a power switch of the target device is turned on; otherwise, another determining is made whether or not the target device is set to operate based on a user's setting. If the target device is set to operate based on the user's setting, the power switch of the target device is turned on; otherwise, the power switch of the target device is turned off.

Abstract: A method of sending a message to a mobile station using a common domain name includes the steps of receiving an email containing a subject and a body, combining the subject and the body into a first message, and determining if the email contains an attachment. If the email contains the attachment, the first message can be converted into a MMS message, and if not, a number of characters in the first message can be counted. If the number of characters is less than or equal to 160 characters, the first message can be converted to a SMS message. If the number is greater than 160 characters and less than or equal to 1000 characters, the first message can be converted to an EMS message. In addition, if the number of characters is greater than 1000 characters, the first message can be converted to the MMS message.

Abstract: Upon receiving an email for a mobile station containing a subject and a body, the subject and body are combined into a first message. If the email contains an attachment, the first message can be converted into a MMS message. If there is no attachment, the number of characters in the first message can be counted. If the number of characters is less than or equal to a first number of characters, the first message can be converted to a SMS message. If the number is greater than the first number of characters and less than or equal to a second number of characters, the first message can be converted to an EMS message. In addition, if the number of characters is greater than the second number of characters, the first message can be converted to the MMS message.

Abstract: A method for implementing an equalizer of an orthogonal frequency division multiplexing (OFDM) baseband receiver is provided. The OFDM baseband receiver includes a channel estimation and tracking module for estimating a channel impulse response of an input signal of the equalizer. A conjugate of the channel impulse response is first calculated. The input signal and the conjugate of the channel impulse response are then multiplied to generate a product signal. The product signal is then taken as the output signal of the equalizer without dividing the product signal by a channel state information, wherein the channel state information represents a square of an absolute value of the channel impulse response.

Abstract: An add-compare-select (ACS) unit generates first path metrics having a first bit-pair and a most significant bit-pair (MSB) each including a high bit and a low bit. A first ACS circuit produces the first bit-pair and a first carry. A limiting circuit generates the MSB based on the first carry, and limits the MSB to a first predetermined value. A MSB maximum select (MS) unit receives an MSB of second path metrics from another ACS unit, and compares the MSBs of the first and the second path metrics to determine MSB decision signals based on maximum likelihood selection. A MSB storage unit stores the MSB of the first path metrics. A reset unit resets the high bit of the MSB of the first path metrics to a second predetermined value when the high bits of the MSBs of the first and the second path metrics reach the first predetermined value.

Abstract: The invention provides a method for controlling the signal gain of a MultiBand Orthogonal Frequency Division Multiplexing (MB-OFDM) baseband receiver. The symbol boundary of a signal is first detected. Power of the signal is then measured according to the symbol boundary, so that a zero-padding section of the signal is not measured. A gain magnitude for amplifying the signal is then determined according to the power of the signal. The signal is then amplified according to the gain magnitude.

Abstract: A process is proposed that enables a widget vendor or aggregator to continuously present widgets via a widget network to a user who previously grabbed and embedded a first widget presented by the vendor or aggregator. The user may initiate the browsing of the widget network from a user placement where the first widget is embedded to choose and grab a second widget from the vendor. Here, the widgets in the widget network can be dynamically maintained and updated by the vendor and can be created at a time after the first widget was grabbed by the user. If the user grabs the first widget over the web and embeds the widget into his/her own placement, the user is presumably interested in the widget and it is likely that the user may also be interested in other widgets created by the same vendor or in the same category of interest.

Abstract: The present invention discloses a method and apparatus of IQ imbalance compensation for a receiver. The repetitive attribute of the preamble in a signal received by the receiver is used to estimate the IQ imbalance parameters. The data carried by the preamble repeats itself every N sampling intervals. A MSE equation is derived based on assuming the ratios between any two sampling points separated by N samples are identical, and the IQ imbalance parameters can be estimated by solving the MSE equation using the LS algorithm. Consequently, the IQ mismatch offset of the signal is compensated according to the estimated parameters.

Thereby, the overall receiver performance and stability can be improved from packet to packet and the estimation algorithm is simplified.

Abstract: A method for updating coefficients in a decision feedback equalizer (DFE). The DFE comprises an ISI canceler for canceling inter-symbol interference (ISI) from a plurality of first signals received from a channel. A first symbol comprising a set of the first signals is decoded to generate a decoded symbol.

According to the decoded symbol and the vector of the error values, a temp matrix is generated. Next, the values of the elements in every diagonal line of the temp matrix are averaged. Finally, the coefficients are updated by the Toeplitz Matrix.

Abstract: A SIP Gateway (SIPGW) coupled to an IP Multimedia Subsystem (IMS) is disclosed that detects when a first party, using a Plain Ordinary Telephone Service (POTS) telephone coupled to the SIPGW and participating in a call, performs a hook flash action. In response, the SIPGW sends to the IMS a first SIP INFO message indicating that the POTS telephone has performed the hook flash.

The AS may also cause a Media Server to receive information from the first party identifying a call feature to be provided, where the call feature is one of simple call hold, consultation call hold, attended call transfer and unattended call transfer.
