The invention deals with the control of a resonant LLC converter by use of control parameters. The primary current flowing in the resonant tank and a voltage at a predetermined point in the resonant tank are monitored and control parameters are set for a high side conduction interval and control parameters are set for a low side conduction interval, the control parameters for the two conduction intervals being: a peak current of the interval and a predetermined voltage of the interval. The resonant converter comprises series-arranged controllable switches to be connected to the supply source. The resonant converter is operated by setting up criteria for turning off a switch in accordance with criteria including the four control parameters.

The invention relates to extracting and embedding auxiliary data from and to a host signal. In an embodiment, the auxiliary data relates to remotely control of an application or a device, such as an interactive toy. Auxiliary data are extracted from a host signal, by periodically (32A-32C) with a predetermined first period searching a first section (33A-33C) of the host signal for a first watermark (34); and, upon detection of the first watermark, searching the host signal for a second watermark (35). In embodiments, information relating to timing and type of action to be performed by a remotely controlled device may be conveyed by the watermarks.

In order, e.g., to provide a line sorter in which acoustic noise resulting from the polygon effect is reduced, there is disclosed a sorter (102) for sorting items of various shapes, sizes and weights, such as postal parcels or airport baggage. The sorter includes a closed loop comprising a plurality of sorting carts (302) for moving along an upper track section, a lower track section and end track sections in a moving direction. The plurality of carts are coupled at couplings (312), which enable the carts to pivot relatively to each other in at least one plane when in operation. Each cart is able to pivot relatively to an adjacent cart at two or more pivot points (404, 414, 1002) where the two or more pivot points are positioned a pivot point distance greater than zero apart in the moving direction of the carts.

The invention deals with the control of a resonant LLC converter by setting up criteria for state parameters of the resonant converter, so that the converter may be operated in a near capacitive mode. The current flowing in the resonant tank and optionally the voltage at the a predetermined point in the resonant tank are monitored, and wherein a switch (a high side switch or a low side switch) is turned off when a first criterion is fulfilled together with a second criterion or optionally a third criterion, the first criterion ensuring a minimum time has lapsed after the switch is turned on, the second criterion being that the absolute value of the current is reaching a predetermined current level, the third criterion being that the voltage at the predetermined point reaches a predetermined voltage level.

There is disclosed a method of passengers (118) claiming their baggage pieces (115) at an aircraft baggage claim area (106) of an airport. In order e.g. to provide such method which improves usage and availability and user experience in view of reference systems, the method includes providing (706) a plurality of destinations (16) at the aircraft baggage claim area of the airport and along each of two lateral sides (112), (114) of the material handling equipment, and choosing (708) towards which of the two lateral sides (112), (114) the one or more pieces of aircraft baggage (15) should be automatically and actively discharged into at least one of the plurality of destinations (116). The method further includes actively discharging (710) the one or more pieces of aircraft baggage (115) from the material handling equipment and into at least one of the destinations (116), and that the one or more aircraft passengers (118) are claiming (712) the one or more pieces of aircraft baggage (115) paired with the one or more aircraft passengers at the at least one destination when the one or more pieces of aircraft baggage is at rest and has stopped moving.

A wind turbine generator with a bearing system is disclosed. The bearing system includes a lockable connection having a bearing surface and a support surface which surfaces are engaged when the lockable connection is locked. Forces from the shaft are transferred via the bearing into the support through the bearing surface, wherein a support angle of the support surface, relative to a shaft plane formed by rotating the shaft around a first axis, which first axis is perpendicular to the center axis and which first axis is comprised in a vertical plane, is in a range from and including 5 degrees to and including 70 degrees.
