A polyaspartate composition is provided which comprises a reaction product of a diamine and a diester reacted at a ratio of diamine equivalents to diester equivalents of from 1:0.95 to 1:0.50. The polyaspartate compositions of the invention may be combined with polyisocyanates to produce polyurea compositions, e.g., coatings, adhesives, sealants, composites, castings, and films, which exhibit a faster cure time along with faster development time for physical properties such as hardness and tensile strength.

A flexibilizing capped prepolymer can include a reaction product of reaction mixture including a polyisocyanate and an isocyanate-reactive component at an equivalent ratio of polyisocyanate equivalents to isocyanate-reactive component equivalents of from 1.4:1 to 2.1:1. The isocyanate-reactive component can include a polyol component and a branching agent component. The branching agent component can include a monoglyceride, a diglyceride, a triglyceride, or a combination thereof having a number average functionality of from 3 to 6 NCO-reactive functional groups. The reaction product is terminated with a capping agent to form the flexibilizing capped prepolymer.

In one embodiment, a method for emitting a sound from an in-ear speaker worn by a subject includes generating, by an audio source of the in-ear speaker, a source audio signal. One or more speakers of the in-ear speaker may emit a sound based on the audio signal and an audio-transport tube of the in-ear speaker may receive the sound. The one or more speakers may be comprised of a singular speaker or a speaker array coupled to a crossover network. The audio-transport tube has an input end coupled to the one or more speakers to receive the sound. An audio reflector of the in-ear speaker may reflect the sound. The audio reflector is coupled to an output end of the audio-transport tube.

In-ear speaker

In one embodiment, a method for determining a dynamic head-related transfer function for a subject includes receiving audio recordings of a sound captured by audio sensors. The sound is emitted by an in-ear speaker worn by the subject. Additionally, a reference signal captured by a microphone coupled to the in-ear speaker and one or more images captured by image sensors are received. The one or more images depict a body pose of the subject while the sound is emitted by the in-ear speaker and may be used to generate a pose representation of the body pose of the subject. A head-related transfer function for each audio sensor is determined based on the pose representation, the audio recordings of the sound, and the reference signal. The dynamic head-related transfer function is determined based on the head-related transfer function for each audio sensor.

Dynamic head-related transfer function

A minimum of one Master Block and one or more Activity Blocks connected (via 'wireless or wired transmission') to a System (the 'electronic device') for a digital and non-digital game, experience, or other engaging activity. Master Blocks can communicate with a System, and can connect to many Activity Blocks. Activity Blocks can communicate with Master Blocks. Furthermore, when multiple Activity Blocks are connected to a single Master Block, they create physical relationships between each other that the Master Block can detect and process and/or relay to the System as a form of input for whatever process the System is running. A user can interact with the System by manipulating the relationships between Activity Blocks and the Master Block.
