Access privileges can be established between the shopping cart and at least one other shopping cart, the other shopping carts being associated with shoppers different from the shopper. A linkage can be established between the Web-based shopping cart and the at least one other shopping cart in accordance with the access privileges. Through the linkage, the shopper can be permitted to access items in the another shopping cart.

Abstract: Systems and methods for providing input/output signal termination with reduced power dissipation on an integrated circuit die are invented and disclosed. One embodiment comprises a method for reducing on die power dissipation while providing on die signal termination that includes receiving a termination reference voltage at a first input of an integrated circuit die, applying the first signal to a single termination element coupled in series between the first input and a receiver input to generate a common node reference voltage, receiving a second signal at a second input of the integrated circuit die, and coupling the second signal to the receiver input.

Abstract: A CMOS switching circuit that includes a charge reservoir and a multiplexer connected to the charge reservoir. The multiplexer receives control signals from a delay line and a control signal line, and it delivers a switching signal to an output terminal. A first set of signals delivered to the control terminals of the multiplexer causes the charge reservoir to deliver charge to the output terminal, and a second set of signals delivered to the control terminals causes charging of the charge reservoir. With the charge reservoir, charge from falling signals is conserved and used to help rising signals at the output, reducing the power required to provide an output switching signal.

Abstract: An integrated circuit (IC) measures a voltage at an interface of the IC. The IC comprises voltage reference, comparator, and control circuits. The voltage reference circuit provides reference voltages responsive to a control input. The comparator circuit compares a first reference voltage with a voltage at the interface. The control circuit receives an output of the comparator and adjusts the control input to provide a second reference voltage closer to the voltage at the interface. A method for measuring voltage at an IC interface comprises generating a first reference voltage, monitoring the voltage at the interface from within the IC, comparing the first reference and interface voltages, generating a second reference voltage responsive to a result of the comparing, replacing the first reference voltage with the second reference voltage, and repeating until an applied reference voltage is substantially equal to the voltage at the interface.

Abstract: A method of dynamically modifying web page displays used in various mobile devices. The method uses a motion detection mechanism to detect whether the mobile device is moving or in motion and then modifies web page displays sent to the device based upon the sensor readings.

In another aspect, the method, system, and apparatus are also capable of modifying the complexity of a display provided to a mobile device based upon the degree of movement and/or motion by the user and/or device.

Abstract: A novel method is presented for mapping a signal driver of an integrated circuit to one of a plurality of interconnect pads. The output impedance of the signal driver and desired slew rate for a signal generated by the signal driver is used to calculate a desired characteristic capacitance to provide a resulting characteristic time constant required to achieve the desired slew rate on a transmission line connected to receive the signal. The characteristic capacitance associated with each at least one possible interconnection path between the driver and pad is estimated, and one of the interconnection paths whose associated characteristic capacitance is substantially equal to the desired characteristic capacitance is selected, and the output driver is then mapped to the pad associated with the selected interconnection path.

Abstract: A novel method and apparatus is presented for controlling the slew rate of a transitioning signal on an integrated circuit transmission line.

Abstract: An electrostatic discharge (ESD) structure for use in an integrated circuit (IC). The ESD structure comprises a metallic resistor and a metallic capacitor that are electrically coupled in series to form a resistor-capacitor (RC) component having an appropriate RC time constant. The RC component maintains a level of charge between ground and a shunt node to ensure that, during an ESD event, electrostatic charge on a power supply, VDD, associated with the ESD structure is shunted via a shunt path from said power supply VDD to said ground. By using metal to create the metal resistor and capacitor, charge leakage problems that result from parasitic capacitance associated with using an RC component comprised of either a poly, active, or nwell resistor in combination a diode are eliminated. By eliminating such charge leakage problems, a more reliable RC component, and thus a more reliable RC time constant, are obtained.

Abstract: A novel method and apparatus is presented for reducing the slew rate signals on transmission lines of integrated circuits. When a transmission line is to be driven to a state by a driver device, the voltage on predrive line controlling the driver device is pulled to a level at or very near to the turn-on threshold voltage the driver device, much more quickly than the turn-on setup time of the driver device. A programmed impedance is then connected between an “on” voltage source and the predrive line to result in a controlled slope of the transmission line signal. Once the voltage level on the transmission line reaches a predetermined reference voltage (e.g., the saturation voltage of the driver device, the predrive line is quickly pulled to the “on” voltage level.
