Abstract: Aspects of the present disclosure relate to methods, systems, and apparatus for wireless gravitational wave communication. In one or more embodiments, a method of wireless gravitational wave communication includes generating one or more gravitational wave signals at a first site. The generating of the one or more gravitational wave signals includes rotating and/or angularly accelerating one or more rotatable masses at a plurality of states. The method includes transmitting the one or more gravitational wave signals to a receiver in a wireless manner, and receiving the one or more gravitational wave signals at a second site using the receiver. The method includes determining (such as by decoding) information from the one or more gravitational wave signals.

Abstract: A variety of applications can include a memory device having a memory die designed to control a power budget for a cache and a memory array of the memory die. A first flag received from a data path identifies a start of a cache operation on the data and a second flag from the data path identifies an end of the cache operation. A controller for peak power management can be implemented to control the power budget based on determination of usage of current associated with the cache from the first and second flags. In various embodiments, the controller can be operable to feedback a signal to a memory controller external to the memory die to adjust an operating speed of an interface from the memory controller to the memory die. Additional devices, systems, and methods are discussed.

Abstract: A sling bar assembly allows variable positioning of a sling on the sling bar assembly. Some sling bar assemblies include opposing sling bar members that are movable with respect to one another in a lateral direction. Some opposing sling bar members are repositionable between a locked position, in which movement of the sling members with respect to one another is restricted, and an unlocked position. Some sling bar assemblies include multiple sling hooks positioned on a sling bar member. Some sling bar assemblies include a biasing member that permits movement of a sling hook with respect to the sling bar assembly in the lateral direction.

Abstract: Methods, system and apparatus for the controlling laundry machines in a laundry facility. A user device receives a list of machines for a laundry facility and displays them on a machine control user interface. The user may then make a selection of a machine, a selection of an operation type and a selection of one or more operational parameters associated with the selected operation type. The selection of the operation type and the one or more operational parameters may be made on the user device or on the selected machine. The machine control user interface may then display the user selections, an estimated duration and a cost. The estimated duration and cost may be based on the selected machine, selected operation type and the one or more selected operational parameters.

Abstract: Devices and techniques for logical-to-physical (L2P) map (e.g., table) synchronization in a managed memory device are described herein. For example, plaintext portion of an L2P map may be updated in a managed memory device. In response to updating the plaintext portion of the L2P map, the updated portion can be obfuscated to create an obfuscated version of the updated portion of the L2P map. Both the updated portion and the obfuscated version of the updated portion can be saved in storage of the memory device. When a request from a host for the updated portion of the L2P map is received, the memory device can provide the obfuscated version of the portion from the storage.

Abstract: An umbrella system includes a support pole connected to a rotating tube positioned around a center tube that extends between the support pole and a center support that is connected to an umbrella frame. The rotating tube has one or more helical grooves therein that are engaged by teeth of a hub which is connected to the umbrella frame. As the rotating tube is rotated, the hub is driven along the length of the rotating tube thereby opening and closing the umbrella frame. In one arrangement system includes a motor housing assembly including a plurality of batteries and a motor that includes a driven gear that meshes with a stationary gear which causes rotation of the rotating tube.

Abstract: In one or more arrangements, an umbrella system includes a support pole connected to a rotating tube positioned around a center tube that extends between the support pole and a upper hub that is connected to an umbrella frame. The rotating tube has one or more helical grooves therein that are engaged by a lower hub which is connected to the umbrella frame. As the rotating tube is rotated, the lower hub is driven along the length of the rotating tube, thereby opening and closing the umbrella frame. In one or more arrangements, the system includes a rotational lock assembly configured to prevent rotation of the rotating tube when locked and permit rotation of the rotating tube when unlocked. In one or more arrangements, the system includes a counterbalance assembly that provides a counterbalance force positioned within a upper hub of the umbrella frame.

Abstract: A body mounting assembly, model vehicle, and method for engaging a model vehicle body to a model vehicle chassis are provided. The body mounting assembly includes a latch assembly. The latch assembly further includes a latch member with a latch engagement surface. The body mounting assembly also includes a retainer assembly. The retainer assembly further includes a retainer engagement surface. The latch assembly is releasably engaged to the retainer assembly when the latch engagement surface and the retainer engagement surface are interlock together. The latch engagement surface and the retainer engagement surface comprise negative engagement angles. A body mount able to be coupled to a model vehicle body includes one of the latch assembly or the retainer assembly and a chassis mount able to be coupled to the model vehicle chassis includes the other corresponding retainer assembly or the latch assembly corresponding to the body mount.

Abstract: A system related to providing multi-layer code rates for special event protection with reduced performance penalty for memories is disclosed. Based on an impending stress event, extra error correction code data is utilized to encode user data obtained from a host. The user data and first error correction code data are written to a first block and the extra error correction code data is written to a second block. Upon stress event completion, pages having user data with the extra error correction code data are scanned. If pages of the first block are unable to satisfy reliability requirements, a touch-up process is executed on each page in the first block to reinstate the first block so that the extra error correction code data is no longer needed. The extra error correction code data is deleted from the second block and the second block is made available for user data.

Abstract: Mobile management method, system and client. The method includes receiving a DNS query for a host name from an application on a client; retrieving reputation data associated with the host name from a local cache on the client; determining a policy for the host name, which is associated with the host name and the reputation data associated with the host name; based on the determined policy for the host name, blocking attempted network flows to a host corresponding to the host name; sending at least attempted network flow metadata related to the blocked attempted network flows to a collector on the client; and transmitting the attempted network flow metadata in the collector to a VPN server pool via a VPN tunnel.

Abstract: Devices and techniques for efficient obfuscated logical-to-physical mapping are described herein. For example, activity corresponding to obfuscated regions of an L2P map for a memory device can be tracked. A record of discontinuity between the obfuscated regions and L2P mappings resulting from the activity can be updated. The obfuscated regions can be ordered based on a level of discontinuity from the record of discontinuity. When an idle period is identified, an obfuscated region from the obfuscated regions is selected and refreshed based on the ordering.
