Abstract: Memory of a storage system is made available (i.e., exposed) for use as host memory of a host, for example, as an extension of the main memory of the host. The host may be directly connected to an internal fabric of the data storage system. Portions of the storage system memory (SSM) may be allocated for use as host memory, and this may be communicated to the host system. The host OS and applications executing thereon then may make use of the SSM as if it were memory of the host system, for example, as second-tier persistent memory. The amount of SSM made available may be dynamically increased and decreased. The SSM may be accessed by the host system as memory; i.e., in accordance with memory-based instructions, for example, using remote direct memory access instructions. The SSM may be write protected using mirroring, vaulting and other techniques.

Abstract: An access point that selectively provides a multicast domain name system (mDNS) message is described. During operation, the access point may receive an mDNS message, where the mDNS message includes an identifier of a group (such as a user group). For example, the identifier of the group may be included in the mDNS message when the mDNS message includes discovery information for a service. Moreover, the identifier may specify the portion of a subnet in a wireless local area network (WLAN) in a geographic region, such as a room, a floor or a building. Then, the access point may determine whether the access point or an electronic device is included in the group. When the access point or the electronic device is in the group, the access point may selectively provide the mDNS message addressed to the electronic device. Otherwise, the access point may drop the mDNS message.

Abstract: A trailer coupler has a fixed frame portion that is connected to a moving frame portion with link arms. The link arms are attached to torsion components that are affixed to both the fixed frame portion and moving frame portion with the moving frame portion located between ends of the fixed frame portion. The moving frame portion has a resting position where the torsion components are at rest and a displaced position where external forces have caused the torsion components to move. The moving frame portion can be displaced through rotation or vertical movement by external forces.

Abstract: A computerised method of trading a fungible instrument, the method comprising: receiving orders from traders for a fungible instrument. The orders each comprise an amount of the fungible instrument to buy or sell, but no price. The orders are matched. The price of matched orders is then fixed at a price based on an outside source at a predetermined time.

Abstract: A load control system may include load control devices for controlling an amount of power provided to an electrical load. The load control devices may be capable of controlling the amount of power provided to the electrical load based on control instructions received from a gesture-based control device. The gesture-based control device may identify gestures performed by a user for controlling a load control device and provide control instructions to the load control device based on the identified gestures. The gestures may be identified based on images received from a motion capture device. A gesture may be associated with a scene that includes a configuration of one or more load control devices in a load control system. The user may perform one or more gestures to program the gesture-based control device to identify a gesture.

Abstract: A method is provided that includes reading a plurality of resistance-switching memory cells comprising a block of data, decoding the block of data using an error correction code decoder, and based on results of the decoding, selectively performing an overwrite-read process to read the block of data. The overwrite read process determines a change in resistance of the resistance-switching memory cells in response to a write pulse.

Abstract: Disclosed herein are various embodiments of methods and systems for drilling a wellbore into an oil or gas production zone to prevent formation damage in the reservoir using underbalanced or near-balanced drilling techniques, wherein a jet pump drilling assembly is used to create a vacuum around the drill bit. The design of this jet pump drilling assembly prevents the flow of all drilling/power fluid from entering a drill bit Only fluids from the reservoir are allowed to enter the drill bit. The assembly includes a barrier to ensure that no drilling/power fluid discharged from the jet pump located above the drill bit can flow back around to the jet pump jet pump suction ports located in the drill bit thus preventing any drilling/power fluid from ever contacting the drill bit.

Abstract: A pulse analysis system or method includes a frequency filter that receives an ultrafast pulse under test and disperses the pulse under test over a frequency range. The frequency filter separates the pulse under test into component frequency slices and provides the frequency slices to a detector coupled to a digitizer, which processes the digitized signal and collects a sonogram characteristic of the pulse under test. The frequency slices are arranged to overlap. Ptychography is performed on the sonogram to obtain characteristics of the pulse under test.

Abstract: This document describes techniques and systems for radar-based gesture-recognition with context-sensitive gating and other context-sensitive controls. Sensor data from a proximity sensor (108) and/or a movement sensor (108) produces a context of a user equipment (102). The techniques and systems enable the user equipment (102) to recognize contexts when a radar system (104) can be unreliable and should not be used for gesture-recognition, enabling the user equipment (102) to automatically disable or “gate” the output from the radar system (104) according to context. The user equipment (102) prevents the radar system (104) from transitioning to a high-power state (1910) to perform gesture-recognition in contexts where radar data detected by the radar system (104) is likely due to unintentional input. By so doing, the techniques conserve power, improve accuracy, or reduce latency relative to many common techniques and systems for radar-based gesture-recognition.

Abstract: Data processing systems and methods, according to various embodiments, are adapted for determining an applicable privacy policy based on various criteria associated with a user and the associated product or service. User and product criteria may be obtained automatically and/or based on user input and analyzed by a privacy policy rules engine to determine the applicable policy. Text from the applicable policy can then be presented to the user. A default policy can be used when no particular applicable policy can be identified using by the rules engine. Policies may be ranked or prioritized so that a policy can be selected in the event the rules engine identifies two, conflicting policies based on the criteria.

Abstract: A load control system may be commissioned using beacon messages. The load control system may include control devices that each include a beacon transmitting circuit configured to transmit a beacon message that comprises an identifier associated with the control device. A network device, such as a mobile device, may discover a control device based on the beacon message received from the control device. In response to discovery of the control device, the control device may be added to a temporary group of control devices for being collectively configured and/or controlled. Control devices may be discovered based on the signal strength at which the beacon messages are received. A mobile device may adjust a discovery threshold for discovering a target number of control devices in the load control system.
