摘要： A voltage controller is operable to generate control signals for controlling an intermediate bus voltage (VIB) in an intermediate bus architecture power system, the intermediate bus voltage comprising a voltage output from a first stage DC-to-DC power converter to at least one second stage DC-to-DC power converter via the intermediate voltage bus in the intermediate bus architecture power system. The voltage controller comprises a receiver operable to receive values of the current input to the first stage DC-to-DC power converter, or the current and voltage output by the first stage DC-to-DC power converter. The voltage controller further comprises an efficiency measuring unit operable to determine a measure of an efficiency of the intermediate bus architecture power system in accordance with the received values. The efficiency measuring unit is operable to: determine a first value of the efficiency measure using the received values corresponding to a first intermediate bus voltage (VIB); and determine a second value of the efficiency measure using the received values corresponding to a second intermediate bus voltage (VIB) higher than the first intermediate bus voltage. The voltage controller also includes a control signal generator operable to generate control signals to cause the first stage DC-to-DC converter to set the intermediate bus voltage (VIB) to a voltage higher than the second intermediate bus voltage if the second efficiency measure value represents a higher system efficiency than the first efficiency measure value, and to a voltage lower than the first intermediate bus voltage if the second efficiency measure value represents a lower system efficiency than the first efficiency measure value.

摘要： A switched mode power supply (SMPS) comprising a feedback unit, voltage feed forward (VFF) compensation signal generator and a transient detector. A VFF compensation signal is only applied to the output of the feedback unit when a transient is detected by the transient detector on the input voltage of the SMPS, thereby saving power and computation time. The transient detector comprises a first comparator to detect that a positive transient has occurred if a difference signal is greater than a positive threshold level; a second comparator to determine if the difference signal is within a predetermined range of positive values and output a result that indicates if the difference signal is within the predetermined range of positive values; and a first calculator to detect that a positive transient has occurred if, out of a first predetermined number of consecutive results of the output of the second comparator, there is at least a second predetermined number of results indicating that the difference signal is within the predetermined range of positive values. The transient detector comprises further features for similarly detecting a negative transient.

摘要： To calculate a control signal for the duty cycle of a switched mode power supply (SMPS), a voltage feed forward compensator is integrated into a feedback unit. A control unit has an adder with a first input to receive a signal dependent upon an output voltage. A second input receives a signal from a feedback circuit, and an output outputs a signal comprising the sum of the signals applied to the inputs; another output outputs a control signal for controlling the duty cycle, the control signal is dependent upon the output signal from the adder; a voltage feed forward compensation signal generator calculates a compensation signal to adjust the control signal depending upon an input voltage of the SMPS; and a feedback circuit between the output of the adder and the second input of the adder calculates a compensated feedback signal and to feed the compensated feedback signal to the second input of the adder

摘要： A wireless receiver for receiving a signal with a characteristic pattern includes a predictor for predicting the presence of a non-zero value of the characteristic pattern. A tracker tracks a noise component in the received signal between predicted non-zero values. The resulting noise component is subtracted from the received signal to output a processed signal, which is then decoded by a pattern discriminator and demodulator. The wireless receiver is less sensitive to noise and interference.

摘要： By evaluating a cell selection criterion S during scans for available public land mobile networks (PLMNs), a user equipment (UE) can avoid network service interruptions by not selecting PLMNs for which there exist no suitable cells. The cell selection criterion can be evaluated based on cell parameters either read during the PLMN selection procedure or locally stored before the PLMN selection procedure. It is possible to reduce the time required for PLMN scans and UE power consumption.

摘要： The invention relates to a wearing parts system (1) intended for the tool of a tilling machine of the type which comprises a holder part (3), having a front end part (8), and an exchangeable wearing and/or replacement part (2), arranged over this end part and comprising a hood-shaped (6) hollow (7) which, when the wearing part (2) is fitted in place, is designed to grip over the end part and is fixed thereto by means of at least one locking device (27) placed through interacting openings (28), the end part and the hollow having front, rear and collateral contact zones (9, 22, 23), each comprising contact faces (10, 25, 26), disposed one on the holder part and one on the wearing part, for the absorption of acting vertical, horizontal and collateral forces Fx, Fy and Fz. The contact faces (25, 26) are designed to interact so as, on the one hand, to limit the pushing-on of the wearing part over the holder part and, on the other hand, to ensure that the contact between the contact faces will be made, primarily, at the common centre M0, of the two radii (of a recess and a projection) essentially in the horizontal plane YZ and secondarily, as the wear has progressed, symmetrically about this mid contact point as an increasingly large contact zone (22′, 23′).

摘要： An embodiment of a method of determining a lower bound for a minimum cost of placing data objects onto nodes of a distributed storage system begins with a first step of assigning a placement of a data object to a node and a time interval which meets a benefit criterion. Assignment of the placement of the data object to the node and the time interval comprises assigning the placement of the data object to a node-interval. The method continues with a second step of continuing to assign additional placements of the data object to other node-intervals which each meet the benefit criterion until a performance reaches a performance threshold. The method performs the first and second steps for each of the data objects. The method concludes with a step of calculating a sum of storage costs and creation costs for the placement and the additional placements of the data objects. According to another embodiment, the data object placed in the first and second steps is chosen on a basis of a triplet of the data object, the node, and the interval which meets the benefit criterion.

摘要： A method of determining data placement for a distributed storage system with a selection of a heuristic class for placing data objects onto nodes of the distributed storage system. The heuristic class meets a performance requirement and provides a replication cost that is within an allowable limit of a minimum replication cost. The method continues with an instantiation of a data placement heuristic selected from a range of data placement heuristics according to the heuristic class. According to one embodiment, the method concludes with the instantiation of the data placement heuristic. According to another embodiment, the method concludes with an evaluation of a placement of the data objects onto the nodes made according to the data placement heuristic. According to another embodiment, the method continues by iteratively performing the selection of the heuristic class, the instantiation of the data placement heuristic, and the evaluation of the data placement heuristic.
