Abstract: A vibrotactile plush device can include at least one transducer configured to generate a plurality of vibrations, at least one control unit configured to receive an input signal from a communication protocol and to transmit a first output signal to the at least one transducer, and a power source. The device can include a vibrotactile material configured to transmit the plurality of vibrations at one or more restorative or therapeutic frequencies to a body of a user. A padding material can be configured to dampen the plurality of vibrations. In some embodiments, the vibrotactile plush device can also be a weighted device and further comprise a heating pad. In some embodiments, the plurality of vibrations can simulate the purring of a cat, and a cover can be configured to possess a cat shape.

Abstract: A method is disclosed which includes receiving an incoming time-varying signal as ambient signal, applying a signal cancellation filter to the incoming time-varying signal to thereby generate an attenuated version of the incoming time-varying signal, selectively choosing one or more selected classes of signals to be broadcasted while other signals are to be attenuated, continually applying the incoming time-varying signal to a classifier to identify presence of the one or more selected classes in the incoming time-varying signal, adding a snippet of a pre-recorded signal associated with each of the identified classes to thereby generate a string of signal snippets associated with the identified classes, and repeating in a loop, combining the attenuated version of the received time-varying signal with the repeated string of signal snippets and broadcasting the combination.

Abstract: A centralized platform for management of substance abuse treatment programs is disclosed. The platform tracks recovery user status across a plurality of third party entities, including treatment entities, healthcare entities, government-mandated programs, and employment-related entities. The user and one or more third party entities may be provided with a set of user interfaces for tracking progress through various treatment phases, and presented with verifiable certification of completion that is coordinated across the third party entities. In some example aspects, the recovery user may be qualified, upon completion of predetermined recovery and treatment program criteria and other training criteria, as a peer recovery specialist. In such instances, the centralized platform may enable the recovery user to be presented as a contact for other, subsequent recovery users to work with in completing various recovery programs.

Abstract: A system for inspecting features of an airframe, the system including a feature inspection device configured to measure an aspect of a first feature and a tracking subsystem configured to determine a position of the feature inspection device when the feature inspection device measures the aspect of the first feature. The system is configured to determine a position of the first feature on the airframe via the feature inspection device and the tracking subsystem, the determination of the position of the first feature being independent from the measurement of the aspect of the first feature.

Abstract: A charging handle assembly for a firearm includes: a charging handle frame having a forward end configured for insertion into an upper receiver of a firearm, a central portion connected to and extending rearward from the forward end, and a base extending rearward from the central portion; a latch arm having a forward hook, the latch arm attached to the central portion of the charging handle frame, the forward hook biased toward the central portion of the charging handle frame to secure the charging handle frame relative to an upper receiver of a firearm; and a cheek rest attached to the base of the charging handle frame. The latch arm is configured to releasably engage the upper receiver of a firearm when the cheek rest is pushed forward and to disengage the upper receiver of the firearm when the cheek rest is pulled rearward.

Abstract: A camera storage apparatus adapted for engagement to a user having a case formed by two elastically engaged sidewalls. An aperture provides access for the camera to an interior cavity and a projection creates a restraint for the camera while in the interior cavity. The elastic edgewall may be stretched by the user to remove or insert the camera into the interior cavity past the projection. A lip extending past the aperture and over the body of the user provides a guide for the camera into the interior cavity so the user need not look at the device during insertion and removal of the camera.
