摘要:
A side air bag is disclosed for a motor vehicle, and takes the form of a three-dimensional airbag which is formed from two super-imposed layers of fabric. The super-imposed layers of fabric, when laid flat, have a substantial common area of super-imposition. Infill pieces formed from either at least one gusset forming insert or from a portion or portions of fabric of one or both of the fabric layers which extend beyond the area of super-imposition are provided. The air-bag has an inflatable region towards the upper part of the air-bag and an inflatable region towards the lower part of the air-bag. The two inflatable regions are separated by a part of the air-bag which is constrained when the air-bag is inflated, to have a thickness less than the thickness of either of the said regions.

A side airbag unit for a vehicle seat including a generally cylindrical gas generator unit having a longitudinal axis. The vehicle seat has a backrest with a front surface and a side surface. In order to achieve the result that the airbag requires little additional space and nevertheless is relatively easy to mount on the vehicle seat, the longitudinal axis extends generally parallel to the front surface and perpendicular to the side surface of the vehicle seat.

According to one embodiment, a method comprises scheduling, by a weighted proportional-share scheduler, access of competing flows to a computing service in accordance with respective weights assigned to the competing flows. The method further comprises autonomously determining, by a controller, based at least in part on received performance measurement for the flows, values of the respective weights assigned to the competing flows for achieving respective performance goals desired for the competing flows. When determined by the controller that the values of the respective weights assigned to the competing flows should be changed for achieving the performance goals, the controller communicates the changed values of the respective weights to the weighted proportional-share scheduler.

A control circuit operable to control the switching of switching elements in a switched mode power supply. The control circuit comprises a switching control signal generator operable to generate control signals for switching the switching elements such that the switched mode power supply converts an input voltage (Vin) to an output voltage Vout). The control circuit further comprises an operation mode setting module which is operable to receive a signal (I) indicative of a current flowing to a load that is connected to an output of the switched mode power supply, and operable to cause the switching control signal generator to generate the control signals so as to operate the switched mode power supply in a continuous conduction mode or a pulse skipping mode in dependence upon the current.

A control circuit, that controls the duty cycle of a switched mode power supply, comprises a reference voltage generator that, responsive to the input voltage exceeding a threshold value, generates a predetermined reference signal. Responsive to the input voltage not exceeding the threshold value, the reference voltage generator receives a signal indicative of an input voltage of the switched mode power supply and generates a variable reference signal dependent upon the input voltage. The control circuit further comprises an error signal generator that receives a signal indicative of an output voltage of the power supply and generates an error signal based on the reference signal generated by the reference voltage generator and based on the output voltage. The control circuit also includes a duty cycle control signal generator that generates the control signal to control the duty cycle of the power supply in dependence upon the error signal.
摘要:
In an intermediate bus architecture power system, a voltage controller that generates control signals for controlling an intermediate bus voltage (VIB) 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. A receiver receives values of the current input to the first stage converter, or the current and voltage output by the first stage converter. The controller determines a first value of an efficiency measure using the received values corresponding to a first VIB, and determines a second value of the efficiency measure for a second VIB higher than the first VIB. Control signals cause the first stage converter to set the VIB to a voltage higher than the second VIB 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 VIB if the second efficiency measure value represents a lower system efficiency than the first efficiency measure value.

A method and a control unit for changing a working mode of a synchronous rectifier. The synchronous rectifier comprises at least one controllable switch having a diode in parallell thereof. The synchronous rectifier is operatively connected to a reactive circuit, and is arranged to receive at least one control signal at a control terminal, for controlling at least one controllable switch. The at least one control signal is pulse-width modulated with a defined duty-cycle. The method comprises adjusting the pulse-width of the at least one control signal between zero percent duty-cycle and the defined duty-cycle at a frequency above a cut-off frequency of the reactive circuit. Thereby, reducing the effect of a forward voltage drop over said diode in the synchronous rectifier.
