摘要： A semiconductor device is provided that includes an optical feedback structure that is monolithically integrated with a VCSEL device and which extends the speed of the VCSEL device beyond the speed to which it would otherwise be limited due to relaxation oscillation. The optical feedback structure does not rely on light emissions from the VCSEL substrate material to produce optical feedback. Consequently, extension of the bandwidth of the semiconductor device through the use of optical feedback is not limited by the absorption threshold wavelength of the substrate material. Furthermore, because the optical feedback structure does not include the substrate, the ability to use optical feedback to extend the bandwidth of the device is independent of the precision with which the substrate thickness can be controlled.

摘要： A collaborative session (e.g., a virtual time capsule) in which access to a collaborative object and added virtual content is selectively provided to participants/users. In one example of the collaborative session, a participant (the host) creates a new session and invites participants to join. The session creator (i.e., the host) and other approved participants can access the contents of a session (e.g., which may be recorded using an application such as lens cloud feature; available from Snap Inc. of Santa Monica, California). A timestamp is associated with each received virtual content, and the users are provided with a timelapse of the collaborative object as a function of the timestamps.

摘要： A collaborative session (e.g., a virtual time capsule) in which access to a collaborative object and added virtual content is selectively provided to participants/users. In one example of the collaborative session, authentication of the collaborative object is performed by all of the users to complete the collaborative session. Each user authenticates the collaborative object, such as using a stamping gesture on a user interface of a client device or in an augmented reality session. User specific data is recorded with the stamping gesture to authenticate the collaborative object and the associated virtual content. In an example, user specific data may include device information, participant profile information, or biometric signal information. Biometric signal information, such as a fingerprint from a mobile device or a heart rate received from a connected smart device can be used to provide an authenticating signature to the seal.

摘要： Semiconductor devices and a method for generating light in a semiconductor device are invented and disclosed. The method includes the steps of forming a vertical cavity surface emitting laser including an active region and an oxide layer, the active region separated from the oxide layer and configured to generate light in response to an injected current and introducing an implant layer adjacent and underneath the oxide layer to confine the injected current to a region of the device where charge carriers are combining to generate light. The semiconductor devices include an implant layer between the oxide layer and the active region. The implant layer prevents lateral leakage current from exiting a region of the device where charge carriers are combining to generate light.

摘要： A collaborative session (e.g., a virtual time capsule) in which access to a collaborative object and added virtual content is selectively provided to participants/users. In one example of the collaborative session, a processor provides users with access to a collaborative object using respective physically remote devices, and associates virtual content received from the users with the collaborative object during a collaboration period. The processor maintains a timer including a countdown indicative of when the collaboration period ends for associating virtual content with the collaborative object. The processor provides the users with access to the collaborative object with associated virtual content at the end of the collaboration period.

摘要： Collaborative sessions in which access to added virtual content is selectively made available to participants/users. A participant (the host) creates a new session and invites participants to join. The invited participants receive an invitation to join the session. The session creator (i.e., the host) and other approved participants can access the contents of a session. The session identifies a new participant when they join the session, and concurrently notifies the other participants in the session that a new participant is waiting for permission to access the added virtual content. The host or approved participants can set up the new participant with permissions for accessing added virtual content.

摘要： Development environments are commonly used to facilitate the development of user interfaces (e.g. windows forms, web forms, etc.). Drawing objects are components that may be used within the development environment to provide visual enhancements to the user interface. An effective method for drawing one or more drawing objects is disclosed herein to draw the drawing objects as windowless shapes within a shape container. The shape container may be configured to participate in a windows message loop (e.g. event handling system), wherein the windowless shapes do not participate in the windows message loop (e.g. lack a windows handle). The shape container listens, for example, within the windows message loop for operations pertaining to windowless shapes, and executes the operations upon the windowless shapes. Computer resources may be efficiently allocated, for example to the graphical user interface during runtime, instead of the windowless shapes consuming resources to participate in the windows message loop.

摘要： Collaborative sessions in which access to a collaborative object and added virtual content is selectively provided to participants/users. In one example of the collaborative session, a participant crops media content by use of a hand gesture to produce an image segment that can be associated to the collaborative object. The hand gesture resembles a pair of scissors and the camera and processor of the client device track a path of the hand gesture to identify an object within a displayed image to create virtual content of the identified object. The virtual content created by the hand gesture is then associated to the collaborative object.

摘要： A collaborative session (e.g., a virtual time capsule) in which access to a collaborative object with an associated material and added virtual content is provided to users. In one example of the collaborative session, a user selects the associated material of the collaborative object. Physical characteristics are assigned to the collaborative object as a function of the associated material to be perceived by the participants when the collaborative object is manipulated. In one example, the material associated to the collaborative object is metal, wherein the interaction between the users and the collaborative object generates a response of the collaborative object that is indicative of the physical properties of metal, such as inertial, acoustic, and malleability.
