Abstract: A method for driving an optical lens system having a first and a second group of optical lenses movable along a linear path parallel to an optical axis by a first and second motor, respectively, and a drive unit, comprises reading (S2, S4) of a present position of the groups and communicating (S6) it to the drive unit. In the drive unit, a command representing a requested optical zoom degree and/or a requested focusing distance is received (S10). Requested positions of the groups, corresponding to the received command, are deduced (S20) by utilizing predetermined lens positioning data available in the drive unit. The predetermined lens positioning data represents positions of the groups causing different combinations of optical zoom degree and focusing distance. The motors are driven (S30, S32) to move the groups to the respective requested positions. The driving comprises applying (S31, S33) of voltage signals over electromechanical materials.

Abstract: A method includes receiving a Bluetooth Low Energy (BLE) advertising message from a user interface (UI) device. The method includes, responsive to a receipt of the BLE advertising message from the UI device: waking up an application module of the first wireless device and authorizing the UI device to remotely control media presentation as presented by the application module. The method includes determining a first determination of whether the first wireless device is paired or is in a current cabled connection with an electronic device that is distinct from the UI device; and in accordance with the first determination being a determination that the first wireless device is not paired with the electronic device and is not in a current cabled connection with the electronic device, automatically terminating the authorization of the UI device to remotely control media presentation as presented by the application module.

Abstract: A method for media presentation in a vehicle includes receiving a Bluetooth Low Energy (BLE) advertising message from a user interface (UI) device. The method includes: waking an application module of the first wireless device; authorizing the UI device to remotely control media presentation as presented by the application module; and determining whether the first wireless device is paired or in a current cabled connection with a vehicle head unit of the vehicle. The method includes, when the first wireless device is paired or in a current cabled connection with the vehicle head unit, selecting the first wireless device for subsequent communication with the UI device to control the media presentation, and when the first wireless device is not paired with the vehicle head unit and not in a current cabled connection with the vehicle head unit, terminating the authorization of the UI device to remotely control media presentation.

Abstract: In some embodiments, a method is provided for identifying a communication interface of an electronic unit attached to a connector of an electronic device. A voltage pulse is generated in the device on a pin of the connector. The voltage on the pin is measured, as it is affected by a load in the unit. The measured voltage is compared with predetermined voltage criteria. Communication interface identification is performed on the unit dependent on the comparison.

Abstract: A card-receiving device for a communication apparatus, such as a handheld device or a personal computer card, receives a circuit card, such as a SIM-card. The device includes a body member having a card-receiving portion, a guide that allows movement of the body member to be performed in relation to a printed circuit board of the communication apparatus, and a switch for controlling an electric circuit interfacing and/or powering the circuit card. The switch includes a first contacting mechanism adapted to directly contact a second contacting mechanism of the printed circuit board for enabling the electric circuit.
