Abstract: Remote computing resource service providers allow customers to execute virtual computer systems in a virtual environment on hardware provided by the computing resource service provider. The hardware may be distributed between various geographic locations connected by a network. The distributed environment may increase latency of various operations of the virtual computer systems executed by the customer. To reduce latency of various operations predictive modeling is used to predict the occurrence of various operations and initiate the operations before they may occur, thereby reducing the amount of latency perceived by the customer.

Abstract: A resource provider is able to manage instance data associated with virtual compute instances running in the resource provider environment. For example, when provisioning a compute instance, the resource provider can obtain data associated with the compute instance and can store this data, for example, in a data store. The resource provider can act as a centralized repository of such data for some or all instances that are running in the resource provider environment. Entities (e.g., users or other compute instances running in the resource provider environment) can query the resource provider to perform various operations (e.g., read, modify, duplicate) on the data being managed by the resource provider for the various compute instances. Any changes to the data for a compute instance, for example, by a user, the compute instance, or a different compute instance, can be saved by the resource provider and propagated to the compute instance.

Abstract: Various embodiments provide systems and methods that collect data regarding game strategy decisions by human players during video game, and utilize the collected data to either adjust or replace behaviors of computer players and/or suggest game strategies to human players during video game sessions. The game strategy decisions may be harvested from human-vs-human and human-vs-computer video game sessions. The data may be harvested from online-connected video game sessions, which may be hosted over an online video game network. Depending on the embodiment, the harvested data can include information regarding game strategies used by players during the video game sessions, the game contexts in which the game strategies were respectively used, and the results achieved by the respective use of the game strategies. Systems and methods described herein may facilitate a computer player having behavior that is (at least partially) “crowd-sourced” based on game strategies used by online-connected video game sessions.

Abstract: An electronic resistor or end of the line power module device that includes a radio frequency identification (RFID) transmitter attached to assist in locating hard to find end of the line devices on supervised alarm system circuitry or non-supervised AC/DC power circuits. Since the RFID transmitter may be found using an RFID verifier, finding an end of the line device may now be easily accomplished.

Abstract: Apparatus and method for reducing generation of acoustic noise in a disc drive. A multi-layer disc drive housing structure includes a housing layer, a plurality of rigid damping layers and a corresponding plurality of interposed visco-elastic damping layers. Characteristics of the various layers are selected by evaluating hypothetical models each having first, second and third theoretical layers, at least one of which is a composite layer made up of multiple layers. Loss factor profiles are evaluated in relation to housing layer resonant frequency to provide an optimum multi-layer structure.

Abstract: Forming a top cover assembly of a disc drive by providing a top cover to a gasket-dispensing device, accelerating a gasket material dispensing head of the gasket-dispensing device over a staging portion of a gasket support portion of the top cover, supplying an uncured gasket material to the accelerating gasket material dispensing head, dispensing a substantially constant increasing thickness gradient of uncured gasket material adjacent the staging portion, discharging a substantially dimensionally uniform bead of the uncured gasket material onto the support surface, applying a substantially constant decreasing thickness gradient of the uncured gasket material adjacent the substantially constant increasing thickness gradient of uncured gasket material and curing the uncured gasket material to form the top cover assembly.

Abstract: An object monitoring system, including a slave system having slave processors (14, 16) and a plurality of cameras (10) for monitoring one or more objects, images of thc cameras (10) being processed by respective ones of the slave processor (14, 16), and the slave processors including sensors (30) assigned to respective cameras (10) and at least parts of the fields of view of the cameras (10) to detect predetermined characteristics of the at least parts and generate a trigger in response thereto. A master system has to master processor (20) including agents (34) assigned to at least one of the objects and having one or more of the sensors (30) allocated thereto, the agents (34) each generating an event on receiving triggers from the one or more allocated sensors (30). An event system (6) receives the events and determines whether an alarm condition exists. A user interface system (8) can configure the sensors (30) and agents (34) and respond to events.

Abstract: A disc drive has a head disc assembly that includes a basedeck with a threaded attachment aperture supporting a rotatable disc surface for storage of data and a rotary positionable read/write head adjacent the rotatable disc surface for writing data to and reading data from the rotating disc surface, a top cover with a mating aperture aligned to the threaded attachment aperture communicating with the basedeck to form an enclosure, a gasket constraint formed in the basedeck with an overlapping portion forming a gasket junction while supporting a tubular gasket sandwiched between the top cover and the basedeck. The tubular gasket has a first end adjacent the overlapping portion and a second end adjacent the overlapping portion; the second end communicates with a main body portion of the tubular gasket to seal the enclosure upon securing the top cover to the basedeck with a top cover fastener.

Abstract: Apparatus in a disc drive for improving resistance of a disc drive disc stack to radially directed mechanical shocks. A disc is disposed about a rotatable spindle motor hub. Opposing first and second disc support members (such as a disc clamp, disc spacers, or a hub flange) circumferentially extend about the outer hub surface and cooperate to apply a clamping force to the disc to secure the disc relative to the spindle motor hub. The disc support members each comprise a circumferentially extending ring of high friction material having a contact surface that axially extends toward the disc. The clamping force applied to the disc is localized at the rings and at nodes extending from the disc support members so that respective gaps are formed between the disc and remaining portions of the disc support members, thereby reducing radial disc slip, increasing disc dampening, and reducing the likelihood of disc coning and warping.

Abstract: A limit stop for defining the range of motion of a disc drive actuator. The limit stop is formed from a single piece of material. It includes a cylindrical contact surface on the distal end of a cylindrical cantilevered beam. The beam is connected to a central mounting shaft by a radially extending bridging element. The compliance of the stop is determined by the material selection and control of certain dimensions.
