Abstract: Autofocusing a camera while zooming may include zooming the lens to a first zoom position, measuring a first object distance from the camera to an object on which to focus, determining a first focus start position using the first object distance, performing a first autofocus using the first focus start position as a starting point, thereby determining a first focus position. A first lookup object distance may be determined based on the first determined focus position. A first correction factor may be calculated as a ratio between the first lookup object distance and the first object distance. The lens may be zoomed to a second zoom position, and a second focus position may be determined using a second object distance based on the first object distance and a second correction factor based on depths of field at the second and first zoom positions.

Abstract: A set of different pilot structures are designed for use in different environments and/or different user behaviours that are expected to occur in a cell. The radio conditions for a user are estimated. Each user is then assigned an area (108A-E) in resource space for its communication, which has a suitable pilot configuration. In one embodiment, the entire resource space is provided with different pilot structures in different parts (110A-D) In advance and allocation of resources to the users are then performed in order to match estimated radio conditions to the provided pilot structure. In another embodiment, allocation is performed first, and then the actual pilot structure is adapted within the allocated resource space area to suit the environmental conditions.

Abstract: A method of autofocusing a camera during a zooming operation is disclosed, comprising zooming the lens to a first zoom position, measuring a first object distance from the camera to an object on which to focus, determining a first focus start position using the first object distance, performing a first autofocusing operation using the first focus start position as a starting point, thereby determining a first determined focus position. A first lookup object distance is determined based on the first determined focus position. A first correction factor is calculated as a ratio between the first lookup object distance and the first object distance. The lens is zoomed to a second zoom position, and a second focus position is determined using a second object distance calculated as a product of the first object distance and a second correction factor based on a ratio of depths of field at the second and first zoom positions.

Abstract: The present invention relates generally to auto focus algorithms for setting a focus of a camera. More specifically, the present invention relates to a method (600) and device for setting a focus of a camera wherein a camera motion level of the camera is continuously measured (S604) during the read-out of pixel data by a rolling shutter image sensor and wherein the auto focus algorithm uses weighted focus measures which are calculated (S612) using the continuously measured camera motion levels.

Abstract: The technology disclosed provides the ability for a subframe to be configured as a “flexible” subframe. As a result, at least three different types of subframes in a TDD system may be configured: a downlink (“DL”) subframe, an uplink (“UL”) subframe, and a “flexible” subframe. While the DL and UL subframes are preconfigured for each frame instance, the flexible subframes are dynamically allocated to be an uplink subframe in one instance of a frame and a downlink subframe in another instance of the frame.

Abstract: What is disclosed is a method for monitoring a subject for cardiac arrhythmia such as atrial fibrillation using an apparatus that can be comfortably worn by the subject around an area of exposed skin where a photoplethysmographic (PPG) signal can be registered. In one embodiment, the apparatus is a reflective or transmissive wrist-worn device with emitter/detector pairs fixed to an inner side of a band with at least one illuminator emitting source light at a specified wavelength band. The illuminator is paired to a respective photodetector comprising one or more sensors that are sensitive to a wavelength band of its paired illuminator. The photodetector measures intensity of sensed light emitted by a respective illuminator. The signal obtained by the sensors comprises a continuous PPG signal. The continuous PPG signal analyzed for peak-to-peak pulse points from which the existence of cardiac arrhythmia such as atrial fibrillation event can be determined.

Abstract: A method and mobile unit facilitate installation of a surveillance camera for monitoring an object of interest in a scene. The surveillance camera acquires a zoomed out image of the scene. The zoomed out image is displayed in a display wherein the zoomed out image has a zoomed out center point. An indicator overlaid on the displayed zoomed out image is displayed in the display, wherein the indicator and the zoomed out center point are displaced in relation to each other by a deviation. The indicator indicates the position of a zoomed in center point of a zoomed in image of the scene. The surveillance camera is directed so that the position of the object of interest and the indicator coincide so that the object of interest is included in a zoomed in image of the scene.
