Summary of the patent applications from Apple Inc. on September 28th, 2023
- A recent patent filed by Apple Inc. describes a User Equipment (UE) that can connect to both a Master Evolved Node-B (MeNB) and a Secondary eNB (SeNB) simultaneously. The UE can receive data packets from both the MeNB and the SeNB through a split data radio bearer (DRB). The control functionality for the split DRB is divided between the MeNB and the SeNB. The UE also receives an indicator specifying which eNB it should use to transmit uplink traffic packets as part of the split DRB. Based on this indicator, the UE transmits the uplink traffic packets to the specified eNB, which can be either the MeNB or the SeNB.
- Another patent filed by Apple Inc. describes a system and method for a user equipment device (UE) to perform multiple transmissions in a wireless communication system. The UE can configure a data structure with transmission configurations for the physical uplink shared channel (PUSCH) that span multiple time transmission intervals (TTIs). The UE receives a message from the network entity that includes a time domain resource assignment field (TDRA) indicating the set of transmission configurations to use. The UE then performs the PUSCH transmissions according to the indicated set of configurations over an unlicensed band.
- Apple Inc. has also filed a patent for a user equipment (UE) that can detect changes in network coverage and alert the user about the change. The UE identifies the specific change from the initial network coverage to a different type of network coverage and generates an alert to inform the user about this change.
- Another patent filed by Apple Inc. describes a power-efficient way of performing cellular communication. It involves a wireless device and a cellular base station exchanging information to indicate that they both support a sleep downlink control information (sDCI) format. They then negotiate an sDCI configuration, which includes selecting parameters based on the type of application being used for communication. The downlink control information is provided during specific subframes according to the sDCI configuration.
- Apple Inc. has filed a patent for a method where a first electronic device detects a triggering condition to control a second electronic device. When the triggering condition is detected, the first device increases the rate of transmission of wireless signals and sends them out. The second device responds to these signals, and based on the responses, a distance measurement is determined. If the distance is below a certain threshold, control of certain components of either device can be enabled by the other device.
- Notable applications:
* A system for privacy-preserving mapping of access points to improve network efficiency. * A method for providing traffic information for specific types of data traffic groups in 3GPP XR communications. * A wearable device that uses gaze detection to authenticate a user.

In addition, the backplane may have a cell gap that is equal to a wavelength divided by four times the birefringence of the fLC layer. In order to further optimize the optical performance of the display module, the wavelength used in determining the cell gap may be a green wavelength between 500 nm and 565 nm.
Eye Tracking Data Filtering (18056526)
Inventor Jacob Wilson
Brief explanation
The abstract describes a method for eye tracking, which involves determining the initial position of a person's pupil in relation to a lens in front of them. It then detects any changes in the pupil position and determines if the updated position is outside a specific area associated with the lens. If it is outside, a replacement position within that area is identified and used for eye tracking. Additionally, if a pixel associated with the person's gaze direction is outside a certain visibility region, a replacement pixel within that region is found. An updated gaze angle is then determined based on the replacement pixel, and eye tracking is performed using this updated angle.
Abstract
Eye tracking is performed by determining an initial pupil position of a user in relation to a lens situated in front of the user, detecting a change in pupil position in relation to the lens to an updated pupil position in relation to the lens, and determining that the updated pupil position is outside a bounding box associated with the lens. The updated pupil position is a replacement pupil position with a replacement pupil position within the bounding box associated with the lens, and the updated pupil position is utilized for eye-tracking functionality. Eye tracking is also performed by determining that a first pixel associated with a gaze direction is outside a visibility region, identifying a replacement pixel within the visibility region, determining an updated gaze angle based on the replacement pixel, and performing eye tracking using the updated gaze angle.

Inventor Mark K. Hauenstein
Brief explanation
The abstract describes a computer system that can display a simulated environment in relation to the physical environment of the computer. When the computer detects a change in attitude (such as a movement or rotation), it adjusts the appearance of a virtual user interface object to stay in the same position relative to the physical environment. The computer can also detect gestures, and if certain criteria are met, it can switch from the first viewing mode to a second viewing mode without adjusting the appearance of the virtual user interface object.
Abstract
A computer system displays, in a first viewing mode, a simulated environment that is oriented relative to a physical environment of the computer system. In response to detecting a first change in attitude, the computer system changes an appearance of a first virtual user interface object so as to maintain a fixed spatial relationship between the first virtual user interface object and the physical environment. The computing system detects a gesture. In response to detecting a second change in attitude, in accordance with a determination that the gesture met mode change criteria, the computer system transitions from displaying the simulated environment in the first viewing mode to displaying the simulated environment in a second viewing mode. Displaying the virtual model in the simulated environment in the second viewing mode includes forgoing changing the appearance of the first virtual user interface object to maintain the fixed spatial relationship.

DUPLEXER WITH IMPEDANCE INVERTERS (18327705)
Inventor Joonhoi Hur
Brief explanation
The abstract describes the use of a device called a duplexer, which is used to separate a transmitter and a receiver that share the same antenna. The duplexer achieves this by using impedance gradients to create impedances that cause balance-unbalance transformers (balun) to block access to the common antenna, rather than duplicating the antenna impedance. This balanced approach results in lower insertion loss compared to a duplexer that simply duplicates the antenna impedance to separate the signals from the transmitter and receiver.
Abstract
A duplexer may be used to isolate a transmitter and a receiver that share a common antenna. By using impedance gradients to provide impedances that cause balance-unbalance transformers (balun) of the duplexer to cut-off access to the common antenna rather than duplicate the antenna impedance, the duplexer is balanced. Such cut-offs may have a lower insertion loss than a duplexer that merely duplicates the antenna impedance to separate the differential signals of the receiver and transmitter from the common mode signal.

Synchronization in a Multiuser Experience (18189403)
Inventor Luis R. Deliz Centeno
Brief explanation
This abstract describes a method for enhancing collaboration in a multiuser communication session. It involves detecting when a user interacts with a virtual object in the session, where multiple devices are involved. The state information, which includes the details of the interaction, is synchronized between the devices. However, when an interaction occurs, the synchronization is temporarily paused on the device where the interaction took place. This leads to inconsistencies between the representations of the session on the different devices.
Abstract
Facilitating collaboration in a multiuser communication session includes detecting initiation of an interaction between a user of a first device and a virtual object in a multiuser communication session, where the first device and a second device are active in the multiuser communication session, and where state information is synchronized among the first device and second device in the multiuser communication session. In accordance with detecting the initiation of an interaction between the user and the virtual object, synchronization of state information is suspended by the first device, where the state information is related to the interaction between the user and the virtual object. A representation of the multiuser communication session at the first device and a representation of the multiuser communication session at the second device are inconsistent in accordance with the suspended synchronization of the state information.

Crowd Sourced Privacy Preserving Access Point Mapping (18187003)
Inventor Rachid Kachemir
Brief explanation
This abstract describes a system that uses privacy-preserving techniques to map access points and improve network efficiency. User devices send reports to a server with information about access points they have connected to, without revealing their exact locations. The server uses this data to generate network topologies, locations, quality scores, and other characteristics. This information is then provided to user devices to help them interact more efficiently with access points and networks.
Abstract
In some implementations, a computing system can perform crowd sourced access point mapping using privacy preserving techniques. For example, a server device can receive access point data reports from multiple user devices that includes various attributes and/or measurements with respect to access points with which the user devices have established connections. The access point data reports can be delivered without identifying the user devices, or users thereof, and their exact locations. Based on the access point data reports, the server device can map locations of access points and relationships between access points to generate network topologies, network locations, network quality scores, and various other characteristics of networks and/or access points. The generated access point data can be served to user devices so that the user devices can improve the efficiency of the interactions between user devices and the detected access points and/or networks.
