Abstract: Edible colorant compositions containing a monoacylated anthocyanin of Compound I and methods of use are provided. The colorant compositions include at least the monoacylated anthocyanin colorant of Compound I extracted from red cabbage and a metal ion, and have a pH from about 6.0 to about 8.0. The colorant compositions can be derived from a non-artificial product and provide a stable, blue colorant that can be used in food products. Specifically, the monoacylated anthocyanin colorant provides color characteristics similar to those provided by the artificial blue colorant, FD&C Blue No. 1.

Abstract: A method for accessing an electronic circuit in an enclosure using near field induction is disclosed. The method involves attaching at least one local access port connector with an external transformer core partition to a near field induction port on an external non-conductive surface of a panel of the enclosure and generating at least one inductive field between the external transformer core partition and an internal transformer core partition. Without a direct electrical connection, the method provides for communicating with the electronic circuit through the at least one local access port connector of the panel using the at least one inductive field.

Abstract: In one embodiment, a power supply comprises a flyback transformer comprising a primary winding and at least two secondary windings. An output voltage is developed across a first one of the secondary windings. The power supply comprises a transistor coupled to the first one of the secondary windings. The output voltage is regulated about a nominal output voltage by operating the transistor in a linear mode when current is flowing through the first one of the secondary windings and by operating the transistor in an off mode when current is not flowing through the first one of the secondary windings.

Abstract: An improved circuit and method for increasing the stability of switch-mode power supplies via frequency fold-back is disclosed. For example, a circuit for increasing the stability of a switch-mode power supply using the compensation signal to control the frequency of the oscillator is disclosed, which includes an operational amplifier that functions to scale the compensation signal. Thus, the switching frequency of the power supply involved is decreased as the load is reduced. This novel use of the compensation signal to control the switching frequency of a switch-mode power supply significantly increases the stability of the power supply as compared to prior switch-mode power supplies. Therefore, the switch-mode power supply may be used for those applications where relatively high stability is desired.

Abstract: A power supply having a flyback topology includes a flyback transformer and a current sense circuit that outputs a current signal indicative of a current output by the power supply. The current sense circuit includes a current sense transformer coupled to the flyback transformer.

Abstract: A method for automatically adapting to statically varying packet size is provided. The method includes receiving a stream of bytes over a physical medium. A packet size is determined from the bytes in the stream of bytes. Further, the determined packet size is used to process packets from the received byte stream.

Abstract: The present invention relates to a method and apparatus for testing components in ATM networks utilizing loop-back based ATM layer testing.
