Abstract: A method and device for detecting whether a headset is on ear. Microphone signals from a plurality of microphones are used to derive a plurality of signal feature measures, which are normalized to a common reference scale. The signal feature measures are weighted based upon detected signal conditions in the microphone signals. The normalized and variably weighted signal feature measures are then combined to produce an output indication of whether a headset is on ear.

Abstract: Performing a transaction in the context of a computing system that has one or more persistent systems coupled to one or more processors over a bus. As an example, the persistent system may serve as at least part of the main memory of the computing system. The transaction might implement multi-versioning in which a record is not updated in place. Rather, each record is represented as a sequence of one or more record versions, each version having a valid interval during which the record version is considered to properly represent the record. The transaction processing uses torn write detection so that recovery processes may use such guards to verify that there are no torn writes. For instance, torn write guards may be used to verify the integrity of record versions as well as the log buffers that refer to the record versions.

Abstract: Caging structures are disclosed for caging or otherwise reducing the mechanical shock pulse experienced by MEMS device beam structures during events that may cause mechanical shock to the MEMS device. The caging structures at least partially surround the beam such that they limit the motion of the beam in a direction perpendicular to the beam's longitudinal axis, thereby reducing stress on the beam during a mechanical shock event. The caging structures may be used in combination with mechanical shock-resistant beams.

The method includes processing messages as events at an event notification engine of a computer system maintaining a database of subscriptions of a plurality of subscribers, the subscriptions including first predicates stored in the database as first datums that are searchable. This includes receiving a message as an event including a second datum. The event is transformed into a query in a query language used to search the database, the second datum being transformed into a second predicate that is included in the query. The query is executed in the database to search the first datums for a first datum that matches the second predicate, and from the first datum, identifying a subscription that matches the event, the subscription being for a subscriber to which the event is routed.

Abstract: Techniques are disclosed for forming integrated circuit structures including a magnetic tunnel junction (MTJ), such as spin-transfer torque memory (STTM) devices, having magnetic contacts. The techniques include incorporating an additional magnetic layer (e.g., a layer that is similar or identical to that of the magnetic contact layer) such that the additional magnetic layer is coupled antiferromagnetically (or in a substantially antiparallel manner). The additional magnetic layer can help balance the magnetic field of the magnetic contact layer to limit parasitic fringing fields that would otherwise be caused by the magnetic contact layer. The additional magnetic layer may be antiferromagnetically coupled to the magnetic contact layer by, for example, including a nonmagnetic spacer layer between the two magnetic layers, thereby creating a synthetic antiferromagnet (SAF).

Abstract: A mammalian C-type lectin receptor type is identified which is shown to bind IgG antibodies or Fc fragments, thus inducing IVIG-related reversal of inflammation associated with various immune disorders. The identification of a DC-SIGN receptor type which interacts with IgG to promote a biological response reducing inflammation associated with immune disorders provides for methods of screening and selecting compounds which may be useful in treating various immune disorders by acting to modulate a DC-SIGN(+) cell to signal a second effector macrophage, causing an increase in expression of the Fc?RIIB receptor and in turn inhibiting a cellular-mediated inflammatory response.

Abstract: Examples of the present disclosure describe smart sensor technology. In an example, a smart sensor module may connect to a sensor using two connectors. Similarly, an external device may connect to the smart sensor module using two connectors, such that, in a pass-through operating state, a signal from the sensor is passed through the smart sensor module to the external device, thereby causing the smart sensor module to appear as an ordinary sensor and enabling the external device to sense the signal from the sensor. In another example, the smart sensor module may have an alternate operating state, wherein additional functionality is enabled, including, but not limited to, communication with a controller, activation of a light emitting diode (LED) or other indicator, or the retrieval and/or storage of information. The operating state may be selected based on the manner in which the external device connects to the smart sensor module.

Abstract: Systems and methods for gamified engineering education are disclosed. Embodiments are directed to an interactive learning exercise designed to allow participants to interact with a complex system, make observations, apply various performance engineering tactics and tools, and optimize the complex system based upon findings. At a high level, the system is a simulated casino floor with multiple pre-defined components, stations, roles, and tasks. The objective of the game is to settle as many player wagers as possible in a set amount of time by “tuning” various aspects of the casino operations. Aspects of the system—the components, stations, roles, tasks, etc.—have analogs in engineering problems. The knowledge gained, including the understanding of how different elements and aspects work with each other, may be applied by the participants to solve future engineering problems.
