Abstract: Methods, systems, and computer program products for providing a shared digital video stream. A first and a second digital video stream are collected. The shared stream is produced based on the first stream so that the first source is visible in the shared stream, but so that the second source is not visible in the shared stream. The first and/or second stream are analysed to detect a trigger, based on detection of a predetermined image and/or audio pattern, the trigger being a detected gazing or a gesture. The shared stream based on the second stream and/or based on the first source but with at least one of a different cropping, a different zooming, a different panning, or a different focus plane selection. The output stream is provided to a consumer.

Abstract: Methods, systems, and computer program products for providing a second digital video stream. A first and a second primary digital video stream are collected from at least two different digital video sources. A first produced video stream is produced based on the first and second primary streams. A second stream is produced based on the first produced stream and also based on the first and second primary streams. The first and second primary streams are time-delayed so as to time-synchronise them with the first produced stream, taking into consideration a latency of the first produced stream. The second produced stream is produced based on the time-delayed first and second primary streams.

Abstract: A method in a control arrangement of a vehicle and a control arrangement for a vehicle for downshifting gears in an uphill slope are presented. The method comprises, when the vehicle is travelling in an uphill slope using an initial gear of the vehicle's automated manual transmission gearbox: simulating at least one speed profile for a downshift to, and a usage of, at least one gear; determining that a minimal speed of each one of the at least one simulated speed profile has a value indicating that the actual speed of the vehicle will be less than or equal to zero in the uphill slope; opening a clutch before is reduced to a value less than zero; activating at least one vehicle brake; shifting vehicle's automated manual transmission gearbox to a start gear; closing the clutch; and deactivating the at least one vehicle brake.

Abstract: A heater (100) for thawing/warming a perishable dielectric load (130) contains: a heating chamber (140) for holding the perishable dielectric load (130) during thawing/warming thereof, a transmitter unit (110) generating electromagnetic energy (RFs) having predefined spectral properties, an emitting element (150) producing an electromagnetic field in the perishable dielectric load (130) based on the electromagnetic energy (RFs) from the transmitter unit (110), a tuning circuit (115) adjusting an overall impedance (Z) of the emitting element (150), the tuning circuit (115) and the heating chamber (140) so that the overall impedance (Z) matches an output impedance of the transmitter unit (110), and a control unit (120) measuring the overall impedance (Z) during thawing/warming of the perishable dielectric load (130) and repeatedly generating at least one control signal (Tn) causing the tuning circuit (115) to adjust the overall impedance (Z) to match the output impedance of the transmitter unit (110).
