Abstract: A method of additive manufacturing an article from a feed material in a chamber includes evacuating at least some of a first gas from the chamber, thereby reducing a pressure therein from a first pressure to a second pressure and reducing the first gas from a first concentration to a second concentration. At least some of the first gas is then gettered from the chamber using a getter, thereby lowering the first gas concentration to a third concentration. The article is then additive manufactured from the feed material in the chamber using the getter as a substrate. The gettering comprises heating the getter at least in part using a fusion source, and the additive manufacturing comprises heating the feed material at least in part using the fusion source.

Abstract: Methods, systems, and devices for wireless communications are described. Generally the described techniques provide for establishing, by a first speaker a control communication link with a second speaker over a first piconet, receiving a signal during an extended synchronous connection-oriented (eSCO) window between a wireless device and the second speaker (e.g., one of a null signal, an acknowledgement (ACK) signal, or a negative acknowledgement (NACK) signal) switching from the second piconet to the first piconet based on the received communication, communicating with the second speaker on the first piconet, and closing the eSCO window based at least in part on the communication.

Abstract: A system for verifying an aircraft instrumentation value comprising: an Air Data Test Module (ADTM) configured to pneumatically simulate at least one instrumentation value based upon a pressure set-point. The pneumatically simulated instrumentation value corresponds to the pressure set point and is reported by an aircraft transponder. A receiver module receives the pneumatically simulated instrumentation value transmitted by the aircraft transponder. A signal processor, is operative to (i) control the ADTM, (ii) command a prescribed instrumentation value to be simulated by the ADTM, (iii) compare the prescribed instrumentation value to the pneumatically simulated instrumentation value, and (iv) issue a pass signal when the values match, and a fail signal when the values differ by a threshold value.

Abstract: A data processing device including a processor and a memory interface, the processor being configured to control the refreshing of a memory by the steps of: periodically forming an estimate of a current rate of decay of a memory and updating an accumulated level of decay of the memory in dependence on the estimated current rate of decay; and causing the memory interface to refresh the memory when the accumulated level of decay exceeds a predetermined threshold. The estimate may be based on a measurement of ambient temperature.

Abstract: A computer-programming tool for generating an implementation of a first data structure, the first data structure representing at least a portion of a computer-programming language. The implementation includes a second data structure and implementation rules which define the syntax rules of the first data structure to be enforced in relation to nodes of the second data structure during a subsequent processing operation which utilizes the implementation in order to establish compliance with the syntax rules represented by the first data structure. Links between nodes of the first data structure are representative of paths of inheritance of substitutability but not implementation and interface between those nodes.
