摘要： An integrated receiver with channel selection and image rejection substantially implemented on a single CMOS integrated circuit is described. A receiver front end provides programable attenuation and a programable gain low noise amplifier. Frequency conversion circuitry advantageously uses LC filters integrated onto the substrate in conjunction with image reject mixers to provide sufficient image frequency rejection. Filter tuning and inductor Q compensation over temperature are performed on chip. The filters utilize multi track spiral inductors. The filters are tuned using local oscillators to tune a substitute filter, and frequency scaling during filter component values to those of the filter being tuned. In conjunction with filtering, frequency planning provides additional image rejection. The advantageous choice of local oscillator signal generation methods on chip is by PLL out of band local oscillation and by direct synthesis for in band local oscillator. The VCOs in the PLLs are centered using a control circuit to center the tuning capacitance range. A differential crystal oscillator is advantageously used as a frequency reference. Differential signal transmission is advantageously used throughout the receiver. ESD protection is provided by a pad ring and ESD clamping structure that maintains signal integrity. Also provided are shunts at each pin to discharge ESD build up. The shunts utilize a gate boosting structure to provide sufficient small signal RF performance, and minimal parasitic loading.

摘要： Digital signals provided by a repeater connected to a plurality of clients by unshielded twisted wire pairs, are converted to analog signals which become degraded during transmission through the wires. Clients convert the degraded analog signals to digital signals. Digital signal phases are coarsely adjusted to have assumed zero crossing times coincide in-time with a clock signal zero crossing. Signal polarity, and the polarity of any change, is determined at the assumed zero crossing times of the digital signals. Pre-cursor and post-cursor responses, resulting from signal degradation, are respectively inhibited by a feed forward and a decision feedback equalizer. The time duration of post-cursor response is further inhibited by a high pass filter and a tail canceller. Phase adjustments are made, after response inhibition, by determining the polarity, and the polarity of any change, at the assumed zero crossing times. Before phase adjustments are made, a phase offset is provided in order to compensate for phase degradations introduced by the unshielded twisted wire pairs.

摘要： Strings entered into a computer system are converted to a common language. The process of converting strings to a common language comprises determining a user-selected target language, associating a user-selected primary input language with the target language and associating a user-selected secondary input language with the target language. The process further comprises obtaining a string of at least one character, converting the obtained string from the primary input language to the target language if the obtained string corresponds to a valid string in the primary input language and converting the obtained string from the secondary input language to the target language if the obtained string corresponds to a valid string in the secondary input language and is not a valid string in the primary input language.

摘要： E-mail applications can be extended to allow recipients to specify quotas indicating maximum numbers of e-mail messages from specific senders based on actions indicated for the recipients to take. A sender can set a quota specifying that no more than five action related e-mail messages should be sent by each sender per week. Quotas may also be set for a number of e-mail messages received that do not require action. Recipient quota information is accessible by senders' e-mail applications so that senders are aware of the quotas before sending an e-mail message. After determining recipients for an e-mail message, an e-mail application can determine quotas for the recipients based on an action indicated in the e-mail message for the sender. The e-mail application can determine if the e-mail message to be sent will approach or reach the quota, and display a notification before the sender sends the e-mail message.
