Abstract: First data is received which encapsulates second data in a hidden compartment. Thereafter, a password is received by a password encoder which uses such password to generate a key. The first data and the key are combined to generate the second data (i.e., the hidden data). The second data is then provided to a consuming application or process. Related apparatus, systems, techniques and articles are also described.

Abstract: A facility for providing an XR device-based tool for cross-platform content creation and display is disclosed. The facility causes a definition of a mixed reality (MR) procedure to be presented by an editing MR device in a virtual application window. Input is received via the editing MR device. The facility interprets the received input as one or more editing actions performed with respect to the MR procedure definition and alters the MR procedure definition accordingly. The facility creates a device-independent representation of the MR procedure based on the altered MR procedure definition.

Abstract: A portion of a source mixed reality (MR) experience is retrieved. Then, the portion of the source MR experience is used to generate a serialized representation including a hierarchy of tagged elements. The hierarchy of tagged elements includes a plurality of MR step elements collectively defining a procedure to be performed by a viewer of an MR experience. Each MR step element has child elements that include an MR step number indicating a position of the MR step in the MR procedure and an MR step ID element indicating an identity of the MR step. The serialized representation is deserialized to generate a portion of a target MR experience to be edited in an MR development tool. The portion of the target MR experience is usable to cause each MR step in the plurality of MR steps to be graphically represented in the MR development tool.

Abstract: Techniques for developing mixed reality applications in connection with a virtual development environment are disclosed. A reference model corresponding to a physical object is received. Then, the reference model is displayed in a virtual development environment. First input arranging an anchor with the reference model in the virtual development environment is received. Then, second input specifying an animation to apply to the reference model is received. The arrangement in the virtual development environment is used to construct a mixed reality application usable to display, in response to detecting an instance of the anchor in a physical environment, the animated reference model in accordance with the arrangement in the virtual development environment.

Abstract: AC power supply circuitry comprising an AC power source is provided. The circuitry further comprises a semiconductor switching device in an AC power line between the power source and an output and a switch that switches the semiconductor switching device between a first state in which it transmits power from the source to the output and a second state in which it does not transmit power to the output. The circuitry further comprises a diplexer that couples communications data on to the power line. Communications data is coupled on to the power line only if said semiconductor device is in said first state.
