The customer can subsequently adjust the committed rate of IOPS by submitting an appropriate request, or the rate can be adjusted automatically based on any of a number of criteria. Data volumes for the customer can be migrated, split, or combined in order to provide the adjusted rate. The interaction of the customer with the data volume does not need to change, independent of adjustments in rate or changes in the data volume, other than the rate at which requests are processed.

The described technology is generally directed towards adapting the demodulation reference signal sent in a wireless resource data block based on channel estimation performance. In general, if the demodulation reference signal received was not successfully able to be used to demodulate the resource data block, the demodulation reference signal density can be increased up to a maximum density, which costs resource elements but improves the channel estimation accuracy.

The network device can use HARQ ACK/NACK data (e.g., a current count or counted over a time period) to determine channel estimation performance, and/or the user equipment can recommend a demodulation reference signal density change.

An output unit outputs (240) information that is useable to activate at least one plant control technology if the determination is made that the plant is to be controlled by the plant control technology.

A method, apparatus, and computer-readable medium for point cloud coefficient coding are provided. Transform coefficients associated with point cloud data are decomposed into set-index values and symbol-index values, the symbol index-value specifying location of the transform coefficient within a set. The decomposed transform coefficients are partitioned into one or more sets based on the set-index values and the symbol-index values. The set-index values of the partitioned transform coefficients are entropy-coded, and the symbol-index values of the partitioned transform coefficients are bypass-coded. The point cloud data is compressed based on the entropy-coded symbol-index values and the bypass-coded set-index values.

In one implementation, a method includes obtaining, for a particular pixel of an image, a real pixel value and a virtual pixel value. The method includes obtaining, for the particular pixel of the image, a first alpha and a second alpha. The method includes generating, for the particular pixel of the image, a combined pixel value as a weighted average of the real pixel value and the virtual pixel value, the weighting being based on at least one of the first alpha and the second alpha.

One embodiment provides for a method of transmitting data between multiple compute nodes of a distributed compute system, the method comprising multi-dimensionally partitioning data of a feature map across multiple nodes for distributed training of a convolutional neural network; performing a parallel convolution operation on the multiple partitions to train weight data of the neural network; and exchanging data between nodes to enable computation of halo regions, the halo regions having dependencies on data processed by a different node.

A work system includes a robot control device, a robot, an image processing device, and an imaging device. The robot control device controls an operation of the robot using a teaching point. The image processing device acquires an image by controlling the imaging device and capturing an image of a workpiece at the teaching point, and stores image data after imaging in association with data of an operation position of the robot corresponding to the teaching point. When a user performs work restoration, the image processing device performs a process of assisting with setting of work restoration by performing control for acquiring an image captured by the imaging device at the operation position of the robot during work restoration and displaying a difference between the image and the stored image.

Systems and methods are described for identifying a subset of interest from a general population and for monitoring a database of daily activity logs associated with the general population in order to identify database entries indicative of an occurrence of a pre-defined trigger event that is associated with a member of the subset of interest. In particular, systems and methods are described that allow a massive database of daily activity logs to be monitored to identify trigger events that have occurred within the past twenty-four hours or other very recent time period. Embodiments are described that may be advantageously used by a provider of credit-related products and/or services who wishes to accurately target prospective customers, identified by the system, based on occurrence of a trigger event, as being in a decision-making phase of credit shopping, for purposes of making a timely and targeted offering relevant to the customers' current activities.

A method and system of managing a utility system having a plurality of subsystems. A utility management server receives performance measurement data of a subsystem of a first utility system is received, from a first utility monitoring device (UMD). A type of the subsystem and a type of the first UMD is determined. Static rules are applied based on the type of subsystem and the type of UMD. Upon determining that the predetermined condition based on the static rules is not met, identifying a subsystem and its corresponding UMD responsible for a malfunction by retrieving contextual information from the measurements megastore server, analyzing the data from the first UMD and the contextual information, and sending a notification to the UMD having the subsystem that has been identified as being the source of the malfunction.

Browser extension for capturing vehicle information from webpage for generating insurance rate quote
A browser extension for facilitating a user of a mobile device obtaining an insurance rate quote for a vehicle (or other property, real or personal) from an insurance provider, wherein vehicle information identifying the vehicle is provided on a webpage. The browser extension searches the webpage for vehicle information identifying one or more vehicles. The user is prompted to select the vehicle(s) for which the insurance rate quote is desired from a list of the vehicles is found on the webpage. The browser extension passes the vehicle information for the selected vehicle to a program application. The program application obtains user information useful for generating the insurance rate quote. Based upon the vehicle information and the user information, the program application generates and displays for the user the insurance rate quote for the vehicle. Additionally, the user may be similarly offered a loan and/or an extended warranty for the vehicle.

A method and system for digital marketing and the provision of digital content allows a user to express, using an application executed on a computing device while a piece of content is being broadcast using an analog or digital signal by an analog or digital radio or television station system, an interest in the broadcast piece of content that is communicated to a backend system. The backend system selects an end point destination that is a pointer to further digital information associated with the broadcast piece of content and communicates the end point destination for the broadcast piece of content to the user who can access the digital information.
