Abstract: Systems and methods for controlling media playback via physical tokens (e.g., items of media content such as photographs) are disclosed. A media playback system can include an audio playback device and a control device. The control device includes a sensor configured to sense a tag of the physical token. The control device can obtain data by sensing the tag of the physical token via the sensor. Based on the obtained data, the control device transmits a request for media content to one or more remote computing devices associated with a media content service, and causes playback of the requested media content via the audio playback device. Additionally or alternatively, spatial audio content can be generated and played back based on a media item characteristic obtained via the sensor data.

Abstract: A vehicle wheel alignment system has a plurality of cameras, each camera for viewing a respective target disposed at a respective wheel of the vehicle and capturing image data of the target as the wheel and target are continuously rotated a number of degrees of rotation without a pause. The image data is used to calculate a minimum number of poses of the target of at least one pose for every five degrees of rotation as the wheel and target are continuously rotated the number of degrees of rotation without a pause. At least one of the cameras comprises a data processor for performing the steps of preprocessing the image data, and calculating an alignment parameter for the vehicle based on the preprocessed image data.

Abstract: A verifiable property record of a property using a distributed electronic ledger. A request is received to add an item to the distributed electronic ledger, where the item is related to the property. A determination is made whether the item is authorized to be added to the distributed electronic ledger including determining whether the source of the request is permitted to write to the distributed electronic ledger. The source of the request may be permitted to write to the distributed electronic ledger if the source has explicit permission or has satisfied one or more verification criteria. If the item is authorized to be added to the distributed electronic ledger, the item is written to the distributed electronic ledger.

Abstract: A flat plate heat exchanger module for use in aerospace applications, automotive applications, industrial applications or similar. The flat plate heat exchanger module comprises a stack of heat exchanger plates, where at least one of the heat exchanger plates further comprises at least one elongated aperture extending across the surface of the heat exchanger plate. This elongated aperture is in fluid isolation from the fluid flowing across the surface of the heat exchanger plate. The use of at least one elongated aperture throughout the stack of heat exchanger plates minimises the overall effect of the expansion and contraction of the metal due to exposure to high temperature gradients. A method of manufacturing such a heat exchanger module is also provided.

Abstract: A method includes loading each section of an executable program code into a respective page of memory, configuring permissions for a first page including a first section of the executable program code to enable execution of the first section loaded into the first page. The first section associated with a first label. The method also includes configuring permissions for a second page of the memory including a second section of the executable program code to disable execution of the second section loaded into the second page. The second section associated with a second label. Responsive to a determination that a transition from the first section to the second section is allowed during execution of the executable program code, the method also includes changing the permissions of the second page to enable execution of the second section of the executable program code.
