IPC Code(s): G02B27/01, G02B1/00, G02B27/42

CPC Code(s): G02B27/0172

Abstract: a waveguide has an output diffractive optical element to couple light out of the waveguide towards a viewer, and a returning diffractive optical element to receive light from the output diffractive optical element and return the received light toward the output diffractive optical element. the output diffractive optical element has overlaid first and second output diffractive optical elements. the first output diffractive optical element receives light from an input direction and couples it toward the second output diffractive optical element in a first direction that is oblique to the input direction. the second output diffractive optical element receives light from the input direction and couples it towards the first output diffractive optical element in a second direction that is oblique to the input direction. the returning diffractive optical element has first and second returning diffractive optical elements that return light opposite the first and second directions, respectively.

20240411142. PUPIL RELAY SYSTEM_simplified_abstract_(snap inc.)

Inventor(s): Brennon Pennell of Canterbury (GB) for snap inc., James Leighton of Abingdon (GB) for snap inc., Nan Ma of Abingdon (GB) for snap inc.

IPC Code(s): G02B27/01, G02B26/10, G02B27/28

CPC Code(s): G02B27/0172

Abstract: a laser scanning projection system comprises a laser source configured to emit light towards a pair of polarizing beam splitters. the polarizing beam splitters direct light to reflect an odd number of times from a plurality of mirrors through one or more quarter waveplates, using a laser scanner comprising a scanning mirror to direct the light across an angular field of view, forming an exit pupil.

20240411183. LIQUID CRYSTAL ALIGNMENT QUALITY AND STABILITY_simplified_abstract_(snap inc.)

Inventor(s): Hemasiri K. Vithana of Chandler AR (US) for snap inc.

IPC Code(s): G02F1/1337, C09K19/02, G02F1/137, G02F1/139

CPC Code(s): G02F1/133703

Abstract: a method for manufacturing a liquid crystal (lc) display includes determining an amount of an lc material to be used in the lc display, determining a silane material to be mixed with the lc material and an amount of the silane material to be mixed with the lc material based on the lc material and the amount of the lc material, mixing the amount of the silane material with the amount of the lc material to generate an lc mixture, and heat treating the lc mixture in contact with a display substrate to bond at least a portion of the silane material to one or more surfaces of the display substrate, such that the silane material acts as a surfactant. the amount of the silane material may constitute at least 0.8% of the lc mixture by weight.

20240411629. REMOTELY CHANGING SETTINGS ON AR WEARABLE DEVICES_simplified_abstract_(snap inc.)

Inventor(s): Piotr Gurgul of Hergiswil (CH) for snap inc., Sharon Moll of Lachen (CH) for snap inc.

IPC Code(s): G06F9/54, G06T19/00

CPC Code(s): G06F9/547

Abstract: systems, methods, and computer readable media are described for remotely changing settings on augmented reality (ar) wearable devices. embodiments are disclosed that enable a user to change settings of an ar wearable device on a user interface (ui) provided by a host client device that can communicate wirelessly with the ar wearable device. the host client device and ar wearable device provide remote procedure calls (rpcs) and an application program interface (api) to access settings and determine if settings have been changed. the api enables the host client device to determine the settings on the ar wearable device without any prior knowledge of the settings on the ar wearable device. the rpcs and the api enable the host client device to automatically update the settings on the ar wearable device when the user changes the settings on the host client device.

20240412423. ADDING GRAPHICAL REPRESENTATION OF REAL-WORLD OBJECT_simplified_abstract_(snap inc.)

CPC Code(s): G06T11/00

Abstract: methods and systems are disclosed for modifying an image. for example, a messaging application implemented on a client device displays an image comprising a real-world object and determines a current location of the client device. the messaging application identifies a venue associated with the current location of the client device and obtains a list of items available for purchase at the venue. the messaging application receives input that selects a given item from the list of items that corresponds to the real-world object. the messaging application adds, to the image, a graphical representation of the given item that corresponds to the real-world object depicted in the image.

CPC Code(s): H04L51/02

Abstract: a chatbot system for an interactive platform is disclosed. the chatbot system retrieves a conversation history of one or more conversations between a user and a chatbot from a conversation history datastore and generates one or more summarized memories using the conversation history. one or more moderated memories are generated using the summarized memories. the moderated memories are stored in a memories datastore. a user prompt is received, and a current conversation context is generated from a current conversation between the user and the chatbot. one or more memories are retrieved from the memories datastore using the current conversation context. an augmented prompt is generated using the user prompt and the one or more memories, which is communicated to a generative ai model. a response is received from the generative ai model to the augmented prompt, which is provided to the user.
