A second network is connected between the transistors. The second network contains a first and second combination. Each of the first and second combinations contains a second resistor and a second switch connected in parallel with the second resistor. The first and second combinations are connected by a third switch.

Abstract:

A variable attenuator and method of attenuating a signal is presented. The variable attenuator contains an input that receives an input signal to be attenuated. A voltage divider between a resistor and parallel MOSFETs provides the attenuated input signal. The MOSFETs have different sizes and have gates that are connected to a control signal through different resistances such that the larger the MOSFET, the larger the resistance. The control signal is dependent on the output of the attenuator. The arrangement extends the linearity of the attenuation over a wide voltage range of the control signal and decreases the intermodulation distortion of the attenuator.

International Classification:

H04B 1/06

US Classification:

4552491, 455254

Abstract:

An amplifier and method of amplifying a signal is presented. The amplifier contains a fixed gain stage, a digitally controllable gain stage, and a continuously variable attenuator connected between the fixed and controllable gain stages. The attenuator and controllable gain stage are controllable such that the gain of the controllable gain stage is decreased when the attenuation of the attenuator reaches a predetermined maximum value and the attenuation of the attenuator is reduced thereafter. The output power level of the amplifier remains constant.

International Classification:

A61B 18/18

US Classification:

606 33

Abstract:

A probe for ablating tissue of a body cavity includes a shaft, an inflatable balloon connected to the shaft, and an electrode structure on or surrounding the balloon. The balloon expands within the body cavity to place the electrode structure in contact with the tissues in the body cavity. Additional electrodes, which are housed within the balloon during insertion into the cavity, can be extended outwardly from the balloon to penetrate the tissues in the body cavity. The electrode structure and the additional electrodes are adapted to transmit electrical energy to tissue of the body cavity in order to ablate the tissues up to a predetermined depth.

International Classification:

G06F 16/182
G06F 16/188
G06F 16/16

Abstract:

A method for reducing write latency in a distributed file system. A write request that includes a volume identifier is received at a data management subsystem deployed on a node within a distributed storage system. The data management subsystem maps the volume identifier to a file system volume and maps the file system volume to a set of logical block addresses in a logical block device in a storage management subsystem deployed on the node. The storage management subsystem maps the logical block device to a metadata object for the logical block device on the node that is used to process the write request. The mapping of the file system volume to the set of logical block addresses in the logical block device enables co-locating the metadata object with the file system volume on the node, which reduces the write latency associated with processing the write request.

International Classification:

Abstract:

Systems and methods for quality of service management are provided. According to one embodiment, a non-transitory computer-readable medium comprises instructions that when executed by the processing resource cause the processing resource to receive, in a normalizing agent, one or more compute load parameters from one or more background compute processes executing on the one or more computer systems and one or more Quality of Service (QoS) parameters for one or more client compute processes executing on the one or more computer systems, convert the one or more compute load parameters to one or more normalized utilization metrics, and execute instructions that cause a processor to adjust a compute resource allocation dedicated to the one or more background compute processes based at least in part on the one or more normalized utilization metrics and the one or more QoS parameters
