Abstract: This disclosure describes techniques for controlling group access to a collaboration technology. The techniques include generating a shared encryption key among authorized producers of content associated with a collaboration technology. The techniques include receiving, by the authorized producers and from authenticated consumers, requests to access the content. The requests may be received in a partitioned manner, such that individual producers are serving a particular subset of the authenticated consumers. In response to receiving the requests, the techniques include sending the shared encryption key from the individual producers to the corresponding subset of authenticated consumers. The techniques include using the shared encryption key to encrypt content by the authorized producers, which may then be decrypted by the authenticated consumers using the shared encryption key, achieving end-to-end encryption of event content.

Abstract: Aspects of the present invention relate to a control module (15) for a vehicle powertrain. The powertrain comprises a transmission (14), an engine (12) and an electric machine (16). The control module (15) is configured to receive an input indicative of a requested upshift and in response to the received signal the control module (15) increases the torque output of the engine (12) prior to the start of the torque phase (20). As the torque output of the engine (12) increases the control module (15) decreases the torque output of the electric machine (16) such that a constant wheel torque is applied to the wheels (18) during the torque phase (20) of the upshift.
