Abstract: Runtime errors in a source code program are detected in advance of execution by machine learning models. Features representing a context of a runtime error are extracted from source code programs to train a machine learning model, such as a random forest classifier, to predict the likelihood that a code snippet has a particular type of runtime error. The features are extracted from a syntax-type tree representation of each method in a program. A model is generated for distinct runtime errors, such as arithmetic overflow, and conditionally uninitialized variables.

Abstract: A detonation system for a perforating gun assembly. The detonation system includes a tandem sub having a first end and a second opposing end. Each of the first and second ends is connected to a respective perforating gun. The tandem sub has an inner bore, and a switch housing residing within the inner bore. The tandem sub also has an addressable switch residing within the switch housing with the switch being configured to receive instruction signals from a surface by means of an electric line. The addressable switch is in communication with a signal transmission pin and a detonator pin. The detonator pin sends a detonation signal from the addressable switch to a detonator in an adjacent perforating gun. The wiring connections for the pins may be pre-assembled before the perforating guns are delivered to the field.

Abstract: The technology relates to lens assemblies for sensor units that provide a low but consistent preload force over the entire operational temperature range of the device. Consistent preloading helps to avoid cracking and plastic deformation. In particular, a compliant structure of a polymeric material is able to expand and contract across temperature extremes. In addition, the polymeric material is arranged in conjunction with a retainer ring to form a discontinuous seal with the lens. This provides in a leak path that is able to reduce condensation or contaminants. As a result, moisture within the sensor unit is permitted to escape, reducing or eliminating impairments on the lens or other parts of the sensor unit that could otherwise impair device operation.

Abstract: Heartbeat consensus forming for the state of a digital ledger built upon a blockchain to provide users with the ability to securely, accurately, and verifiably share state information between distrustful parties is provided herein. The digital ledger is hosted in a networked environment, accessible by multiple parties. Heartbeat transactions allow clients, who are not in direct communication with one another and may distrust one another, to verify the integrity of the digital ledger via consensus. The consensus is readily verifiable by each client on its own machine and allows the ledger to be recovered to an agreed-to state in the event of a fault initiated by a client or the host of the ledger, whether malicious or otherwise. The digital ledger is freely movable to different hosts in the event of a fault.
