US09414767B2	Method and EKG trigger device for correcting an EKG signal in magnetic resonance image acquisition In a method to correct an EKG signal, the EKG signal is acquired, and used for R-spike triggering, during a magnetic resonance (MR) image acquisition sequence that produces interference signals in the EKG signal generated by gradient jumps, wherein the gradient jumps repeat at a fixed time interval, and wherein the duration of a cardiac cycle measured via the EKG signal is at least five times the time interval.

US09420058B2	Stream-based data deduplication with peer node prediction Stream-based data deduplication is provided in a multi-tenant shared infrastructure but without requiring “paired” endpoints having synchronized data dictionaries. Data objects processed by the dedupe functionality are treated as objects that can be fetched as needed. As such, a decoding peer does not need to maintain a symmetric library for the origin. Rather, if the peer does not have the chunks in cache that it needs, it follows a conventional content delivery network procedure to retrieve them. In this way, if dictionaries between pairs of sending and receiving peers are out-of-sync, relevant sections are then re-synchronized on-demand. The approach does not require that libraries maintained at a particular pair of sender and receiving peers are the same. Rather, the technique enables a peer, in effect, to “backfill” its dictionary on-the-fly. On-the-wire compression techniques are provided to reduce the amount of data transmitted between the peers.

On the other hand, if the native message is not well-formed, the canonical message is generated in a manner that the canonical message may be used to access the raw bits of the message, and that includes sufficient information for some downstream processing to determine that the message was not well-formed. That downstream processing may optionally then perform compensatory actions to regain access to the application specific data, and may potentially use information from the canonicalized message to do so.

US09419777B2	Full duplex operation in a wireless network Multiple wireless devices in a network perform full duplex communication in which the transmission path and receiving path are spatially separated to allow simultaneous transmission and receiving. The wireless devices can either be controlled using a centralized, or point, coordination function or a distributed coordination function.

A full-duplex wireless device measures signal being transmitted by its transmitter and estimates parameters that can be used to cancel the contribution of the locally transmitted signal to the locally received signal concurrently being received during the transmission. The transmit antenna and the receive antenna of a full-duplex wireless device can be configured to be spatially isolated from each other to minimize interference between the antenna functions.

US09419642B1	Ultra low power dual quantizer architecture for oversampling delta-sigma modulator Power consumption of analog-to-digital converters (ADCs) is one important requirement for automotive and consumer devices. One flavor of an ADC is a dual quantizer architecture for oversampling delta-sigma modulators. The dual quantizer delta-sigma modulator has a first quantizer for digitizing the output of the loop filter and a second quantizer for digitizing the input of the quantizer.

Furthermore, the improvement allows the second quantizer to run at a much slower sampling rate than the first quantizer. Advantageously, the improvement provides reduction in power consumption and the overall area of modulator.
