  • Publication number: 20230039214
    Abstract: Systems and methods for performing a compliance check on a proposed transfer of one or more digital assets between a user and a counterparty. In some embodiments, one or more attribute values of the counterparty may be received, the one or more attribute values comprises a first attribute value indicating a status of a distributed ledger address of the counterparty. One or more corresponding attribute attestations may be accessed from a distributed ledger, and may be checked against the one or more attribute values. For instance, it may be checked whether each attribute attestation includes a cryptographic proof of the corresponding attribute value, and/or whether the cryptographic proof is electronically signed by a trusted entity. Additionally, or alternatively, it may be determined, based on the first attribute value indicating the status of the distributed ledger address of the counterparty, whether one or more compliance requirements are triggered.

  • Patent number: 9756699
    Abstract: A sensor interface includes on-chip relaxation oscillator circuit and a PLL that operate cooperatively to generate a highly accurate clock signal on-chip using low-power components. A photodiode generates a current signal based on an optical signal that is representative of a sensor signal. An ADC that operates based on the highly accurate clock signal generates a digital signal based on the current signal generated by the photodiode, and a processor processed the digital signal to estimate sensor data within the sensor signal. Examples of characteristics that may be sensed can include environmental characteristics (e.g., temperature, humidity, barometric pressure, etc.) and/or biomedical characteristics (e.g., body temperature, heart rate, respiratory rate, blood pressure, etc.). If desired, an amplifier processes the photodiode-provided current signal before it is provided to the ADC. Also, one or more CDACs that generate feedback currents may be used to reduce noise sensitivity of the sensor interface.

  • Patent number: 9413375
    Abstract: A CMOS analog and audio front-end circuit includes an enhanced analog-to-digital converter (ADC) that achieves a desired signal-to-noise-and-distortion (SNDR) and an analog-front-end transmit (TX) digital-to-analog converter (DAC). The enhanced ADC includes an improved single Op-Amp resonator coupled to a feed-forward loop and can substantially reduce signal transfer function (STF) peaking of the enhanced ADC. The CMOS analog and audio front-end circuit is integrated with a baseband processor.

  • Patent number: 8452428
    Abstract: Aspects of a method and system for detecting and identifying electronic accessories or peripherals utilizing a hardware audio CODEC are provided. In this regard, a hardware audio CODEC may be operable to compare one or more voltages on one or more biased pins of an accessory or peripheral port to one or more reference voltages and generate one or more digital representations of the one or more voltages on the biased one or more pins. An accessory or peripheral attached to the accessory or peripheral port may be identified based on the comparison and/or the generated one or more digital representations. The one or more bias voltages may be controlled based on a result of the comparison and/or the generated digital representations. The one or more bias voltages may be reduced after an attached accessory or peripheral has been identified.

  • Patent number: 8401502
    Abstract: Provided is a method and system for controlling current characteristics in a transceiver having a transmitter. The transmitter includes a plurality of current cells. Each cell is configurable for operating in different modes. The method includes determining a first probability associated with transmitting data at a particular symbolic level and determining a second probability associated with each cell being used during a transmission at the particular symbolic level. Next, one of the modes for each cell is selected in accordance with anticipated performance requirements. An average current of the transmitter is then calculated based upon the determined first and second probabilities and the selected modes.

  • Patent number: 7991752
    Abstract: Provided are techniques for savepoint processing. One of a savepoint statement, a rollback to savepoint statement, and a release savepoint statement is received. It is determined whether to propagate the received one of the savepoint statement, the rollback to savepoint statement, and the release savepoint statement to a data source based on an asymmetrical model in which a nested level of savepoints on a federated server side is capable of being greater than a nested level of savepoints on a data source side and wherein a two-tiered data structure is used to preserve savepoint information in the asymmetrical model. In response to determining that propagation is to occur, the one of the savepoint statement, the rollback to savepoint statement, and the release savepoint statement is propagated to the data source.

  • Patent number: 7987233
    Abstract: A system and methods for facilitating multiparty communications sessions with a plurality of participants and for dynamically designating a communications session manager. More particularly, a system and methods, including protocols, for: establishing a multiparty communications session between a plurality of participants and their respective communication devices in a full-mesh topology; establishing a dynamically designated session manager uniquely associated with a first participant of the multiparty session and, hence, such participant's communication device; as necessary, adding and removing participants and their respective communication devices from the multiparty communications session; and, designating, or electing, another participant as session manager when the first participant exits the multiparty communications session. The methods also enable participants to maintain consistent lists of session participants and establish peer to peer communication links between the participants.
