摘要： A method of providing a workpiece with an anodised aluminium surface with varying colour. The anodised surface is added colour, such as evenly, so that a colour concentration profile exists through the depth, where after a portion of the outer layer is removed to arrive at colour corresponding to a particular depth.

摘要： A method for compensating for acoustic influence of a listening room on an acoustic output from an audio system including at least a left and a right loudspeaker, the method comprising determining a left frequency response and a right frequency response, designing a left compensation filter FL, and a right compensation filter FR, and during playback applying the left and right filters to left and right channel inputs. According to the invention, a target response in the listening position is simulated, and the left and right compensation filters are designed to filter transfer functions based on the simulated target function multiplied by an inverse of the left/right frequency responses. By relying on a simulated target instead of relying on an empirical approach, the general impact of a room can be more accurately captured by the target functions.

摘要： An amplifier arrangement comprising first and second power amplifiers (T1, T2) having drains connected to positive and negative drive voltages, respectively, and gates connected to an input signal. The arrangement further comprises first and second current sensors (1, 2) for detecting first and second drain currents from the power amplifiers, processing circuitry (3) adapted to identify the smallest drain current, and a feedback control loop (5) and means for driving a bias current dependent on a feedback signal through a resistor connected between the input signal and the gate of an inactive one of the first and second power amplifiers. The control loop will keep the idle current constant in the transistor with the lowest current (the inactive transistor). Thereby, the current running in the transistor which does not deliver current to the load will be fixed at a desired value.

摘要： An apparatus with a touchpad for detecting gestures performed by a user and interpreting the gestures independently of the user's actual arbitrary location and the gestures corresponding gesture orientation relative to the touchpad. The touchpad comprises a proximity detection system for detecting a movement performed with a finger by the user in the proximity of the touchpad and a touch detection system for gesture performed by the user while the finger is in contact with the touchpad. In operation the following steps are performed: - by the proximity detection system detecting a pro.x i m i ty-posi t ion P of an object in close proximity to the touchpad; - by the touch detection system detecting a touch-position T of the object while in contact with the touchpad; - determining from the proximity location P relative to the touch-position T a user-direction towards the user; - from the user-direction relative to a predetermined touchpad default- orientation adjusting the orientation of the gesture prior to interpreting the gesture with respect to a gesture-associated command and finally executing the command.

摘要： A solid state relay and a method for controlling a signal path between an AC-signal output and a load in a power amplifier assembly are disclosed. The relay comprises a first and a second MOSFET having a common gate junction, a common source junction and wherein and wherein a drain terminal of a first MOSFET and a drain terminal of a second MOSFET form relay terminals. The solid state relay further comprises a control circuit comprising a positive side comprising a first controlled current generator configured to provide a first control current to the gate junction, and a negative side comprising a current mirror circuit configured to sink a second current from the source junction. Hereby, a generic solid state speaker relay has been disclosed. The relay performs up to the most stringent demands regarding pop/click on high quality products. It can be used to ground wire break, hot wire break and BTL (Bridge Tied Load) break. The design is rather tolerable to different MOSFETs and very competitive in quality and price.
