摘要： A switched mode power supply comprises a control signal generator arranged to generate first and second control signals via first and second outputs, respectively, which are coupled to respective first and second inputs of a switching stage, by means of respective first and second control signal paths. The switching stage is arranged to, responsive to the first and second control signals, alternately charge and discharge the reactive element by coupling it alternately to first and second supply voltages. An adjustable delay stage in one of the first and second signal paths is arranged to control an adjustable delay so that a first delay experienced by the first control signal passing from the control signal generator's first output to the switching stage's first input is substantially equal to a second delay experienced by the second control signal passing from the control signal generator's second output to the switching stage's second input.

摘要： A powder carrier, to which a powder layer containing a metal powder is applied, is provided by an automatic powder carrier feed. A first joining partner is pressed onto the powder layer located on the powder carrier so as to bond a powder layer portion to the first joining partner. The first joining partner is raised from the powder carrier together with the powder layer portion bonded to the first joining partner, and the powder layer portion bonded to the first joining partner is arranged between the first and second joining partners. A sintered join is produced between the first and second joining partners by pressing the first and second joining partners against one another such that the powder layer portion makes contact with both the first and second joining partners. The powder layer portion is sintered as the joining partners are being pressed against one another.

摘要： A semiconductor chip includes: a semiconductor substrate having driver circuitry configured to drive an array of electronic devices; a metal layer above the semiconductor substrate, the metal layer having an array of contacts electrically connected to the driver circuitry and configured to provide an electrical connection between the semiconductor chip and the array of electronic devices; and a plurality of structures formed in the metal layer and/or in a layer between the metal layer and the semiconductor substrate, the plurality of structures being visually unobstructed at a side of the metal layer which faces away from the semiconductor substrate. Each structure of the plurality of structures is physically encoded with a pattern that corresponds to a location of an individual pair of contacts within the array of contacts or a location of a group of adjacent pairs of contacts within the array of contacts.

摘要： Exemplary embodiments include a method, performed by a session management function (V-SMF) of a visited public land mobile network (VPLMN), for establishing a user-requested PDU session to be routed through the user's home PLMN (HPLMN). Such embodiments include receiving, from an access management function (AMF) in the HPLMN, a first request to establish a home-routed PDU session, wherein the first request identifies an SMF (H-SMF) in the HPLMN. Such embodiments also include sending, to the H-SMF, a second request to create the home-routed PDU session. The second request can include an identifier of a resource in the V-SMF associated with the PDU session; and one or more indicators of whether the V-SMF supports respective one or more features related to receiving, from the H-SMF, an identifier of a resource in the H-SMF that is associated with the PDU session. Embodiments also include complementary methods performed by the H-SMF.

摘要： According to an embodiment of a semiconductor device, the semiconductor device includes a semiconductor mesa having source zones arranged along a longitudinal axis of the semiconductor mesa and at least one body zone forming first pn junctions with the source zones and a second pn junction with a drift zone. The semiconductor device further includes stripe-shaped electrode structures on opposite sides of the semiconductor mesa and separation regions between neighboring ones of the source zones. At least one of the electrode structures includes a gate electrode. In the separation regions, at least one of (i) a capacitive coupling between the gate electrode and the semiconductor mesa and (ii) a conductivity of majority charge carriers of the drift zone is lower than outside of the separation regions.

摘要： A method in a first base station for obtaining channel state information from a user equipment is provided. The first base station is comprised in a wireless communication system. The wireless communication system further comprises the user equipment. The first base station estimates (403) a first offset value for a first set of subframes based on a first channel information. The first base station further estimates (404) a second offset value for a second set of subframes based on a second channel information. The first base station transmits (405) the estimated first offset value and the estimated second offset value to the user equipment. The first base station then obtains (407) channel state information from the user equipment. The channel state information is based on the transmitted estimated first offset value and the estimated second offset value. The channel state information is to be used for transmission in the first base station.
