    摘要： The systems and methods described herein allow greater access to a banking platform via a mobile device. The customer can initiate a financial transaction using a mobile device, a bank can inform the customer of the nearest financial transaction terminal to perform that service, and the customer can complete that financial transaction at the financial transaction terminal using the mobile device as a user interface. While conventional systems may use a mobile device to transmit payment information at a point of sale terminal of a brick-and-mortar merchant, the embodiments described herein can allow a customer to conduct a transaction at a financial transaction terminal using the mobile device to initiate a transaction at a location away from a financial transaction terminal, to locate the nearest financial transaction terminal providing the required services, and as a user interface while communicating with the financial transaction terminal.

    摘要： A circuit for providing a reference voltage can be widely used in audio applications. However, at startup an abrupt start in the reference signal can cause undesirable audible artifacts. A circuit employing feedback of a reference voltage to control the charging of a capacitor which provides the reference voltage can be used to provide a smooth startup to the reference voltage. The circuit contains a differential pair for steering a fixed current source from one path to another as the reference voltage increases. The steered current can then be mirrored into one ore more current mirrors where the newly mirrored current can be squeezed to zero when the difference between a desired reference voltage and the reference voltage approaches zero. This newly mirrored current can be used to charge a capacitor which is used to provide the reference voltage.

    摘要： An integrated audio codec includes a high-pass filter to prevent damage to personal computer speakers and other components. The audio codec may be compliant with HD audio standards and can operate with generic software drivers. Tuning of the high-pass filter is provided through an external pin-out where either an external capacitor or external resistors provide an ability to tune the high-pass filter. In one implementation, a tuning voltage is digitized into a tuning code used by a digital high-pass filter. In addition, multiplexers can be used to insure only the audio path leading to the speakers is filtered.

    摘要： An audio processing system that includes an audio filter having one or more elements capable of having state, such as a capacitor, an inductor or a delay. A saturation detector is configured to detect saturation of the audio filter and to generate an output when saturation of the filter is detected, such as a switch control signal. A switch is connected to the audio filter and the saturation detector, wherein the state of one or more of the elements of the audio filter is changed when the saturation detector provides the output to the switch, such as when the switch shorts the element and causes the energy stored in the element to be dissipated.
