Abstract: A device with three flat mirrored panels connected by two-way hinges with a contrasting color pattern located on each panel and the ability to customize lightening and music elements, provides an adult the ability to individualize sensory stimulation and use multiple positioning options of the device during tummy time with a child in order to promote the child's gross motor development.

Abstract: A handheld appliance having a body and an attachment, the body including an outer tube and fluid flow path extending from a fluid inlet to a fluid outlet within the outer tube and a printed circuit board (PCB) arranged within the fluid flow path wherein, the PCB is housed within a housing. The body may further include an inner wall and the inner wall provides the housing for the PCB and the fluid flow path may extend around the housing. The housing may be generally rectangular and may extend across an internal radius of the outer tube. The fluid flow path may extend around both sides of the housing. The housing may include a heat sink which may be in contact with the fluid flow path on one side and with components on the PCB on the other side.

Abstract: A removable rail for mounting over an AK iron sight assembly of an AK type rifle includes a pair of brackets that fit outer side surfaces of an AK iron sight assembly. At least one pressure clamp is disposed on a side of at least one bracket of the pair of brackets. When the pressure clamp is in an open position, the pair of brackets can be slid over the AK iron sight assembly for mounting or for removal. When the pressure clamp is in a closed position, the pair of brackets are held in a non-moving engagement with the outer side surfaces of the AK iron sight assembly. A fixed AK rail, another type of AK rail, and a method for adding a small arms accessory rail system to an AK rifle by mounting a rail over an AK iron sight assembly are also described.

Abstract: An adapter tip for cleaning an area around a gas tube entrance into the upper receiver of an AR rifle uses an AR charging handle of the AR rifle as an insertion handle for the adapter tip. The adapter tip includes an adapter tip body having a first leg and a second leg extending at an angle from the first leg. The first leg has a notch in a first leg interior surface shaped to accept a forward angled section of an AR charging handle. A forward extension portion of the adapter tip has a first extension end and a second extension end. One or more forward posts are mechanically coupled to and extend forward from the second extension end of the forward extension portion. A method to clean an area around a gas tube entrance into an upper receiver of an AR rifle is also described.

Abstract: A unified bolt and bolt carrier cleaning tool comprising a cylindrical body having a bolt scraper arrangement formed at a first end and a bolt carrier scraper arrangement formed at an opposite end. The bolt scraper arrangement includes a well having two scraper blades shaped to conform to the outer surfaces of the bolt face of a bolt assembly of a weapon. The bolt carrier scraper arrangement includes three longitudinal scraper blades formed in the outer surface and end of the body, the blades being shaped to conform to an inner surface of a bolt-receiving chamber of the bolt carrier. Preferably the tool further comprises a first transverse bore threaded for receiving an auxiliary cleaning tool. Preferably, the tool further comprises a second transverse bore and associated circular recess having scraper blades for cleaning the surfaces of a firing pin extracted from the bolt.

Abstract: In an example, a method for secure publication of content is described. The method may include encrypting content with a media key. The method may also include providing the encrypted content to a client device associated with a private key and a public key. The private key may be stored at the client device. The method may also include encrypting the media key with the public key. The method may also include providing the encrypted media key to the client device.

Abstract: A network includes a plurality of wirelessly interconnected self-organizing network (SON) devices for relaying signals in a self-organizing network and a field device for originating output signals. The sensor is configured to transmit the output signals to at least one of the SON devices, and the SON devices do not originate signals but only relay signals originated externally. At least one of the SON devices is self-powered by harvesting energy from an adjacent energy source.

Abstract: A diaphragm diagnostic system for use in an industrial field device has a diaphragm and a diagnostic feature. The diaphragm is configured to couple the field device to a process fluid and has a plurality of layers. A first layer of the plurality of layers is exposed to process fluid of an industrial process. A diagnostic feature is coupled to the diaphragm to monitor an electrical parameter of the diaphragm and responsively infer an operative state of the diaphragm based on a change in the monitored electrical parameter.
