Abstract: A method, system, and computer program products are provided for updating the location of a cursor in a display window on a trading screen when certain events occurs. In a preferred embodiment, as market conditions change, the market information may be rearranged on a screen. To reduce the chances of missing a market opportunity by sending orders or managing them, the cursor moves in association with the market information such that the cursor appears fixed to the market information until a user moves the pointer device.

Abstract: A digitally controlled frequency generator includes an oscillator module for generating a first clock signal having an oscillating frequency, a programmable control module operable so as to generate a control signal corresponding to a desired frequency, and a direct digital frequency synthesizer coupled to the oscillator module and the programmable control module for receiving the first clock signal and the control signal therefrom, and for generating a second clock signal having the desired frequency based on the first clock signal from the oscillator module and the control signal from the programmable control module.

Abstract: A system for administering the distribution of digitally distributable works, comprises an encapsulation facility operable to encapsulate a digitally distributable work with predetermined conditions of use to create an encapsulated work, and distribution means for distributing the encapsulated work from a transferor in possession thereof, to a transferee. The encapsulated work has a state which is alterable between an enabled state in which the digitally distributable work is unconditionally enabled for use, and a disabled state in which the digitally distributable work is disabled for use. The system also has a switching means operable to switch the state of the encapsulated work to be in the disabled state upon transfer of the digitally distributable work form the transferor to a transferee, and to be in the enabled state when the predetermined conditions of use are complied with by the transferee.
