Methods for managing a robot arm are disclosed. In one method, during a movement of the robot arm in an axis thereof, a signal collected by a sensor equipped at a frame of the robot arm is received. A change in strength of the received signal is detected, where the change is caused by an offset between a position of a reference mark equipped at the robot arm and a position of the sensor. An original point of the axis of the robot arm is determined based on the detected change. Further, robot systems, apparatuses, systems, and computer readable media for managing a robot arm in the robot systems are disclosed. The original point of the axis of the robot arm may be determined without a dedicated calibrating tool, and then the robot arm may be calibrated based on the original point accurately.

An information collection module receives an incident report request from a user of a browser running a network application on a client system to thereby provide a page in the browser. The information collection module collects incident data including user interactions with the page, client system features and operations associated with executing the network application, and a document object model (DOM) of the page. An annotation tool of the network application receives annotations of the page from the user for inclusion in the incident data, and a server-side incident manager receives the incident data. The server-side incident manager includes a rendering engine that renders the document object model and the annotations, and an incident analyzer that displays the collected user interactions, and client system features and operations, and the rendered document object model and annotations.

Page-based incident correlation for network applications

A method and system for generating an automated Internet connection is provided. The method includes receiving from a first communication hardware device of a first user, a first telephone number and a first Internet protocol (IP) address. A second telephone number and a second Internet protocol (IP) address are received from a second communication hardware device of a second user. A request for connecting the first communication hardware device to the second communication hardware device via an Internet connection is received and it is determined that the second communication hardware device is currently connected the first communication hardware device. The request is transmitted to the second communication hardware device. Based on the second user approving the request, the second IP address is automatically transmitted to the first communication device and a secure private Internet link between the first communication hardware device and the second communication hardware device is generated.

A plurality of messages comprising a stream of sensed data is received from an Internet of Things (IoT) device. A plurality of rules is identified. Responsive to a received message of the plurality of messages, the plurality of rules are distributed into a rule index tree based upon a cost model which minimizes a cost for analyzing the plurality of rules to determine whether or not each of the plurality of rules can be applied to the received message. The rule index tree is used to identify a set of rules of the plurality of rules that can be applied to the received message. The set of rules is applied to the received message to generate an outgoing message.

The present disclosure relates to methods and systems for storing and querying data. According to the embodiments of the present invention, two-layer indexes are created for multi-dimension data, wherein the primary index is created based on two or more dimensions to retrieve respective data units of the data, while the secondary index is created based on specific dimensions to retrieve respective data blocks in the data unit. Correspondingly, when receiving a multi-dimension query request for data, the primary retrieval first determines a data unit including the target data based on a primary index, and then the secondary retrieval quickly locates a data block including the target data based on the secondary index. In this way, the multi-dimension retrieval can be efficiently performed. Moreover, by appropriately setting the size of a smallest data block, the I/O efficiency of data access will be significantly enhanced.
