Abstract: Apparatus and methods for assisting breastfeeding are disclosed where the device is a feeding aid which attaches to an individual in a hands-free manner so that an infant can latch on and suck either expressed breastmilk or formula. The device provides a raised surface that allows the baby to latch and which contains openings which are connected to a tube that originates at a reservoir that holds the desired liquid such as expressed breastmilk or formula for the nourishment of the baby. Several openings can serve as a conduit for the suction to allow for the sensation of breastfeeding and stimulation of the mother's nipple and areola to promote breast milk production. A flow regulator may adjust the flow of the liquid coming to the baby at each feeding.

Abstract: A method of creating and trading derivative contracts based on an average trading price of an underlying asset over a calculation period is disclosed. Typically, an underlying asset is chosen to be a base of an Asian derivative and a processor calculates a cumulative realized average price reflecting an average trading price of an underlying asset during a calculation period. A trading facility display device coupled to a trading platform then displays the Asian derivative and the trading facility transmits Asian derivative quotes from liquidity providers over at least one dissemination network.

Abstract: A computer system for calculating a time deposit volatility index comprising memory configured to store at least one program; and at least one processor communicatively coupled to the memory, in which the at least one program, when executed by the at least one processor, causes the at least one processor to receive data regarding options on time deposit derivatives; calculate, using the data regarding options on time deposit derivatives, the time deposit volatility index; and transmit data regarding the time deposit volatility index.

Abstract: A computer system for handling missing or infrequent data used for calculating an index is described. The computer system uses the data approximation scheme for calculating a credit volatility index. The computer system includes a memory configured to store at least one program and at least one processor communicatively coupled to the memory, in which the at least one program, when executed by the at least one processor, causes the at least one processor to receive data regarding options and, when data for a complete input data set is missing after a predetermined period, retrieve or generate estimated data points needed to calculate the index. The data points may be for credit default swap index derivatives using data regarding options on credit default swap index derivatives. The processor may generate a credit volatility index and transmit data regarding the credit volatility index.

Abstract: An automated trading exchange having integrated quote risk monitoring and quote modification services is disclosed. The automated trading exchange is configured to receive orders and quotes, and have associated trading parameters such as a risk threshold. The automated trading exchange typically generates a trade by matching the received orders and quotes, where quotes belong to an overall quote group, to previously received orders and quotes. The automated trading exchange otherwise stores each of the received orders and quotes if a trade is not generated. The automated trading exchange then determines whether a quote has been filled as a result of the generated trade, and if so, determines a risk level and an aggregate risk level associated with said trade. The computer compares the aggregate risk level with the market-maker's risk threshold, and if the threshold is exceeded, automatically modifies at least one of the remaining quotes in the quote group.

Abstract: Systems and methods for creating and disseminating an interest rate swap volatility index based on an underlying interest rate swaption, and for creating and trading derivative investment products based on the interest rate swap volatility index, are disclosed. In one aspect, an interest rate swap volatility index based on an underlying interest rate swaption is calculated. The interest rate swap volatility index may be accessed by a processor of a trading platform and a standardized, exchange traded derivative may be created based on the calculated interest rate swap volatility index. Information associated with the interest rate swap volatility index derivative may then be transmitted for display.
