An optical sensor module has a controller, a sensor array, present state decision circuitry, and a pattern recognizer. The sensor array comprises a plurality of CMOS sensor pixels, wherein the sensor array is configured to supply one of a plurality of analog sensor signals at each of a sequence of sample times, wherein at each of the sample times, the one of the plurality of analog sensor signals is derived from one or more of the plurality of CMOS sensor pixels. The present state decision circuitry is configured to compare the one of the plurality of the analog sensor signals with a respective controller-selected reference voltage and to generate therefrom a respective single state decision signal. The pattern recognizer is configured to assert a pattern recognition signal whenever a plurality of sequentially generated single state decision signals matches a currently active one of a set of one or more reference sequences of single state decision signals. The controller is configured to assert a host system trigger signal when the pattern recognition signal is asserted a predefined number of times in sequence.

Embodiments describing methods performed by a system comprising Network functions including at least a Session Management Function and a User Plane Function for performing a UPF re-anchoring for an application triggered at a User Equipment over an established Packet Data Unit (PDU) Session, where when the system receives the initial trigger for a service triggered by the application (e.g., a DNS request or an application level request), a determination is made by the system based on the information related to the application that re-anchoring of the UPF for that application into a local UPF closer to the UE is required. When re-anchoring of the UPF is successful, the initial trigger is discarded, and the UE is instructed to establish a new PDU session over the local UPF for that application.

Application triggered setup of distributed anchor for edge computing

Devices implementing light communications use waveguides to efficiently collect light used for the light communications and propagate that collected light to a sensor. More particularly, light collected from one or more sensors propagates along a TIR waveguide until disrupted by a diffusive element, which effectively directs the propagating light to a sensor. In so doing, the solution presented herein increases the amount of light available for the light communications and/or reduces the number of sensors needed for the light communications, e.g., by providing light collected from multiple different locations to a single sensor. The waveguide solution presented herein may be implemented inside a device and/or along an exterior surface, e.g., housing or casing, of a device.

Use of waveguides and lenses to improve light communication reception in devices

The present invention relates to method for modifying process parameters based on optimum operation performance criteria for a metal working process, said method comprising the steps of inputting standard process parameters for at least one product to be machined and generating operational data based on the standard process parameters. Operational data is compared with optimized operation performance criteria and is presented to a decision-making entity. This entity may be allowed to modify the process parameters so as to improve operation of the metal working process.

System for optimization of industrial machine operation through modification of standard process parameter input

A method for selecting optimum operation performance criteria for a metal working process. The method includes the step of developing a process model relating process parameters for the operation with performance variables for said operation, wherein the process parameters and performance variables are retrievable via integrated multiple data sources, and selecting at least one optimization technique to define a function, said function including process parameters. Moreover, the method includes generating the function for optimization by using acceptable tolerances of a product to be machined as a basis to define ranges for performance variables along with ranges for process parameters, and applying the at least one optimization technique to said function, whereby optimum operation performance criteria are calculated for the process model including process parameters and performance variables to obtain a set of requirements to be used for controlling the metal working process.

Method and machine system for controlling an industrial operation

The light communication solution presented herein uses waveguides with multiple entrances to efficiently collect light used for light communications and propagate that collected light to a sensor. To that end each waveguide entrance, or at least all but the initial waveguide entrance, is configured to not only collect and input the light into the TIR waveguide, but also to maintain TIR of light already propagating within the TIR waveguide. In so doing, the solution presented herein increases the amount of light available for light communications. Further, because each waveguide may channel light from multiple collection points to a single sensor, the solution presented herein reduces the number of sensors needed for the light communications. The solution presented herein facilitates the implementation of light communications for a wide variety of devices (e.g., cellular telephones, tablets, smartphones, smart watches, smart glasses, etc.) and/or in a wide variety of scenarios.

According to a first aspect of embodiments herein, the object is achieved by a method performed by a mobile terminal for uploading a file in a communications network. After the mobile terminal () has selected a buffering module to be used for uploading the file, it sends () to the selected buffering module, the file to be uploaded in the communications network. The mobile terminal receives () a notification from the selected buffering module. The notification is about an estimated time to any one or more out of: upload start and upload end. The mobile terminal then refrains () from re-sending to the selected buffering module the file to be uploaded in the communications network until the estimated time to any one or more out of: upload start and upload end has expired.

Paging and tracking a wireless communication device

A method and a vehicle as well as a method and a user equipment for enabling a network node to manage paging of the user equipment are disclosed. Moreover, a method and a network node for managing paging of a user equipment are disclosed. The user equipment sends, to the vehicle, an identification of the user equipment by use of a direct wireless communication connection. Then, the vehicle sends, to the network node, the identification of the user equipment. The network node sends, to the user equipment, a control message instructing the user equipment to apply a second DRX cycle, wherein the second DRX cycle is longer than a first DRX cycle. The network node also receives, from the vehicle, position information of the vehicle, whereby the network node, upon paging of the user equipment, sends a paging message, based on the position information of the vehicle, to the user equipment. Corresponding computer programs and carriers therefor are also disclosed.

Methods and vehicle, network node and user equipment for enabling efficient paging

For transmitting data between a node () of a mobile network and a further node (), the further node sends downlink data packets to the node () of the mobile network. The downlink data packets carry a destination address corresponding to a user equipment () connected to the mobile network. For implementing an inband data channel between the node () of the mobile network and the further node (), the further node () inserts data destined to the node () of the mobile network into at least one of the downlink data packets and marks this downlink data packet as including data destined to the node () of the mobile network. The node () of the mobile network receives the downlink data packets from the further node () and identities, on the basis of the marking, the least one downlink data packet including data destined to the node () of the mobile network. The node () of the mobile network then extracts the data from the identified downlink data packet. A corresponding inband data channel may also be used in the uplink direction.
