In one aspect, the present invention provides an order slicer that receives an order that to trade a financial instrument. The order associates a trading strategy with said order. The trading strategy is replaceable. In another aspect, an interface accepts a trading strategy of an order to trade a financial instrument. A transmitter transmits the trading strategy to an order slicer.

By supplying auxiliary power to a blade's optional components, instead of polling the blade for the power requirements of a fully configured module, each installed component can be individually polled and the values summed to produce a more accurate value representing the actual power needs of a blade system prior to booting.

A computer system provides for changing the power states of data-handling devices in response to a detection of a change in the redundancy associated with energy-transfer devices.
摘要:
In at least some embodiments, a system comprises an electronic device having an adjustable hardware inventory and control logic coupled to the electronic device. The control logic initially allocates a first amount of power to the electronic device based on predetermined maximum power needs of the electronic device and later allocates a second amount of power to the electronic device based on a determination of a true hardware inventory of the electronic device.

Alerts are transmitted to subscribers to an alerts service in response to events that occur within a gaming environment. Communication within the gaming environment is limited to specific game consoles and the gaming service. A subscriber to the alert notification service can be alerted when a friend joins the gaming service to play a game, or can select other events for which an alert is requested to be sent to the subscriber. In response to any predetermined event occurring within the gaming environment, an alerts service provides an alert or message that is transmitted through a secure firewall and outside the gaming environment. The alert message can be in the form of a pop-up that appears on a user's instant messaging service, or an email, or a message that is transmitted through a mobile communication service to a cell phone or other portable communication device.
摘要:
Real time or near real time assessment of the quality of securities transactions is accomplished by intercepting order and execution communications between trader and broker, comparing the execution data with contemporaneous market data relative to the transaction or transactions involved, and informing the trader of that comparison. This is accomplished without interrupting or impeding the trader-broker communications, except that a broker-trader communication may, if desired, be interrupted and relevant data aggregated until the aggregate reaches a desired value. It is preferred that the comparison be between the volume-weighted average price of the securities transaction and the volume-weighted average price of the market data for that security, over the life of the order. A particular effective way to communicate the quality evaluation to the trader is disclosed.

摘要:
A charge pump power converter efficiently provides electrical power by dynamically controlling a switch matrix of the charge pump that includes a flying ultra-capacitor CUF. Instead of open-loop oscillator-based control, a dynamic controller provides power upon demand by sensing the output voltage and changing the operating frequency of the charge pump in response. Moreover, this closed-loop dynamic control intrinsically voltage regulates the output voltage of the charge pump power converter without the inefficient addition of a step-down voltage regulator, downstream of the power converter. In addition, this closed-loop dynamic control allows for maintaining a desired output voltage even with variations in the input voltage. Further efficiency is achieved by controlling the charging and discharging of the flying ultra-capacitor CUF, both in rate of current change and in voltage ripple.
