Abstract: A method of operating a procedural training user interface system involves displaying an interactive guided process of a first user using at least one augmented reality (AR) layer through an AR device worn by a second user, where a representation of first user hands is displayed. The second user interactions may be detected during the interactive guided process, where the second user attempts to superimpose second user hands on the representation of the first user hands in the at least one AR layer. The interactive guided process of the second user may then be displayed using the AR layer through an AR device on the first user and the AR device on the second user. If the first user hands and the second user hands are not superimposed in the AR layer, the first user or the second user may be notified to take corrective action.

Abstract: The present invention is related to the field of therapeutic delivery platforms. Such therapeutic delivery platforms are based upon the formation of proteinacous exovesicles that bind nucleic acid payloads (e.g., mRNA, siRNA, shRNA etc.). These nucleic acid payloads may hind to the proteinacous vesicle either directly or as an adduct of a linker molecule. As one example, the linker molecule may be an arc 3?UTR that is bound to an Arc protein exovesicle.

Abstract: A multimodal biometric authentication system utilizes a bulk absorption characteristic of human tissue that is measurable using a photoplethysmography (PPG) sensor. One disclosed method of operation includes extracting bulk absorption features from biometric data obtained using a PPG sensor and generating a first biometric template. Additional biometric features are also extracted from biometric data obtained using a second biometric sensor and a second biometric template is also generated. An authentication output signal is provided in response to the first biometric template matching a first stored corresponding enrolled biometric template and the second biometric template matching a second stored corresponding enrolled biometric template.

Abstract: A digital information encoder including a divider configured to divide a block of information into a plurality of sub-parts, an initial bit allocator configured to perform an initial allocation of bits to a KTH sub-part of said plurality of sub-parts, a processor configured to compute an estimated number of bits for encoding said KTH sub-part, and a bit allocation adjuster configured to obtain an adjusted bit allocation for said KTH sub-part by adjusting said initial allocation of bits to said KTH sub-part based, at least in part, on said estimated number of bits, wherein the encoder encodes said KTH sub-part using said adjusted bit allocation for said KTH sub-part.

Abstract: A system and method for precisely locating a mobile device at a precise geographical distance and messaging to communication devices carried by persons in specific areas is disclosed. The method utilizes at least two elements, a mobile device and at least one location tag. When activated, the mobile device will interact with all of the location tags in range and determine the location tag most practically near. The mobile device will then download detailed local information from the location tag most practically near. The messaging system may be used to selectively send messages to communication devices known to be within range of location transmitters or tags in a predetermined area.

Abstract: A method to wirelessly control an entity having an attached transponder is disclosed. A geographical zone is defined. The geographical zone can be defined by allowing a user to define and load to a transponder a plurality of waypoints, each waypoint defined by a geographical coordinate and a radius originating from the geographical coordinate. The geographical zone can also be defined by selecting a plurality of coordinates that are loaded to a transponder and mapped on a pixilated image. The microprocessor in the transponder is programmed to determine the occurrence of an event associated with the status of the entity in relation to the geographical zone. Finally, the microprocessor is configured to execute a configurable operation if the event occurs.

The method may further include generating a speech signal (720) from the plurality of information frames, and generating an output signal (725) by switching between the comfort noise signal and the speech signal based on a voice activity detection.

Abstract: A communication device (10) can include a transceiver (12), a transducer or microphone (14) coupled to the transceiver for receiving voice input from a user, and a processor (16) coupled to the transceiver. The processor can be programmed to receive (32) a predetermined type of phone call or an indication of a caller indication from a calling party and warp (38) a voice input from the user of the communication device based on the caller indication. How the predetermined type of phone call is determined can be done in a number of ways including using an optional caller identification module (18). The caller ID module can provide information on whether the caller is recognized or whether the caller ID information is unavailable.

Abstract: In a speech encoder/decoder a pitch delay contour endpoint modifier is employed to shift the endpoints of a pitch delay interpolation curve up or down. Parficularly, the endpoints of the pitch delay interpolation curve are shifted based on a variation and/or a standard deviation in pitch delay.
