Abstract: Improved methods and systems are described that improve and enhance payment transaction technologies using node association in a wireless node network. In general, a master node related to a payment receiver may detect a signal from an ID node related to a payment provider as the ID node approaches the master node. The master node may then determine if the ID node desires to associate with the master node for a payment transaction based upon a first part of information within the detected signal, such as an identified item being purchased in the transaction. If desired, the master node and the ID node associate for the payment transaction, and the master node then submits payment transaction data to a server. Such payment transaction data is based upon a second part of information within the detected signal, such as an identified payment source for the transaction.

Abstract: For various applications (for example, a Virtual Assistant), mechanisms that are capable of collecting user queries and generating responses are being used. While such systems handle structured queries well, they struggle to or fail to interpret an unstructured Natural Language (NL) query. The disclosure herein generally relates to data processing, and, more particularly, to a method and a system for generating responses to unstructured Natural Language (NL) queries. The system collects at least one NL query as input at a time, and generates a sketch, where the sketch is a structured representation of the unstructured NL query. Further by processing the sketch, the system generates one or more database queries. The one or more database queries are then used to search in one or more associated databases and to retrieve matching results, which are then used to generate response to the at least one NL query.

Abstract: A detonator to activate energetic materials in downhole well environments that can be transported and operated safely. The detonator comprises a switch coupled to a power source and the energetic materials. The power source may or may not be a part of the detonator. The switch creates a default closed switch between the power source and the energetic material. The switch can communicate with an actuator in response to engaging a gun assembly. The switch can create an open switch in response to communicating with the actuator. The switch forms a short circuit when configured to the default closed switch and forms an open circuit when configured to the open switch. The energetic material is activated in response to the mechanical switch forming an open switch and power is provided by the power source.
