A current source generates, with high efficiency, a current that is substantially constant over a wide range of output voltages. This current is injected into the first end of a series-connected string (hereinafter referred to as string) of LEDs, with the second end of the string connected through a resistor to ground. The voltage developed across this resistor, which is a measure of current flow in the series string, is fed back to the current source, wherein feedback maintains nearly constant current output over a wide range of output voltages. A switch, such as a field effect transistor (FET) is placed in parallel with each LED in the string. A level shift gate driver couples a pulse width modulated control signal to the gate of each FET. When the FET across a particular LED is on, substantially all the current flows through the FET rather than the LED, and little or no light is emitted. Because the one resistance of the FET is very low, the power dissipated in the FET (current squared times resistance) is also very low. With the FET turned on, the forward voltage drop of the LED it is controlling drops to near zero, since little current is flowing through the LED. However, because the current source is designed to provide constant current over a wide range of output voltages, the current flow through the other LEDs in the series string changes little. When the FET is turned off, substantially all of the current flows through the associated LED, turning it on. By modulating the duty cycle of each FET, the brightness of each associated LED may be varied smoothly over its full range.

When mixing cutting between video cameras viewing a common scene from different viewpoints, geometric transforms that vary from image to image are applied to one or both camera outputs so as to create an apparent point of view that moves along on a path joining the viewpoints of the cameras.

Low-frequency bandwidth extension in the form of dynamic electrical equalization may be applied to loudspeakers so long as the excursion capability of their drive units as well as velocity limits of any port(s) or excursion limits of any associated passive radiator(s), and the power limits of the drive units are not exceeded. The bandwidth extension maximizes low-frequency bandwidth dynamically such that excursion is fully utilized over a range of drive levels, without exceeding the excursion limit. Additional limiting control is available for port air velocity or passive radiator excursion, and loudspeaker drive unit electrical power. The system applies to open back, closed box, vented box, and more complex box constructions consisting of combinations of these elements for loudspeaker designs using design parameters appropriate to each system.

In a coaxial two-wheeled vehicle, an attitude controller (84) calculates motor torque Tgyr for maintaining a base so that it has a target angle from deviation between base angle command θref serving as attitude command and current base angle θ₀ calculated by using a gyro sensor (13) and an acceleration sensor (14). On the other hand, at a position proportional controller (86R), a differentiator (88R) and a velocity proportional controller (89R), there is performed PD control with respect to deviation between rotation position command Prefr of a motor rotor (92R) for right wheel and current rotation position θr of a motor rotor (92R). A current control amplifier (91R) generates motor current on the basis of added value of motor torque which is the control result and estimated load torque T₁ calculated by using pressure sensors to drive the motor rotor (92R).

A driving support ECU initializes a target trajectory calculation parameter at a start of LCA; calculates, based on the target trajectory calculation parameter, a target trajectory function representing a target lateral position in accordance with an elapsed time from the start of LCA; and calculates a target control amount according to the target trajectory function. When it is determined that the own vehicle has crossed a boundary white line, the driving support ECU again initializes the target trajectory calculation parameter, and calculate the target trajectory function based on the target trajectory calculation parameter.

A landing position/orientation of a foot (22) to be landed in a landing action of a robot (1) such as a biped mobile robot or the like is estimated, and a desired footstep path for the robot (1) is set up. Based on the estimated landing position/orientation and the desired footstep path, a future desired landing position/orientation is determined in order to cause actual footsteps of the robot (1) (a sequence of landing positions/orientations of the foot (22)) to approach desired footsteps. Using at least the determined desired landing position/orientation, a desired gait for the robot (1) is determined, and the robot (1) is controlled in operation depending on the desired gait. For determining the desired landing position/orientation, mechanism-dependent limitations of the robot (1) such as an interference between the legs thereof, etc., and limiting conditions of an allowable range in which a desired ZMP can exist are taken into consideration.

In various exemplary embodiments, systems include a segmentor to segment text binary image data to a first plane. A subtractor subtracts text binary image from binary image data to generate a non-text binary image data in a second plane. A converter converts non-text binary image data in the second plane into non-text gray scale image data in the second plane. A first compressor compresses the text gray scale image data in the first plane. A second compressor compresses the non-text gray scale mage in the second plane.

The present invention relates to a 3D time-of-flight camera for acquiring information about a scene, in particular for acquiring depth images of a scene, information about phase shifts of a scene or environmental information about the scene. The proposed camera particularly compensates motion artifacts by real-time identification of affected pixels and, preferably, corrects its data before actually calculating the desired scene-related information values from the raw data values obtained from radiation reflected by the scene.

The present invention provides a system and method for parallel imaging that performs auto-calibrating reconstructions with a 2D (for 2D imaging) or 3D kernel (for 3D imaging) that exploits the computational efficiencies available when operating in certain data “domains” or “spaces”. The reconstruction process of multi-coil data is separated into a “training phase” and an “application phase” in which reconstruction weights are applied to acquired data to synthesize (replace) missing data. The choice of data space, i.e., k-space, hybrid space, or image space, in which each step occurs is independently optimized to reduce total reconstruction time for a given imaging application. As such, the invention retains the image quality benefits of using a 2D k-space kernel without the computational burden of applying a 2D k-space convolution kernel.

A variable capacitance element includes a movable element provided above a substrate using supporting portions and support beams so as to be displaced from the substrate. An insulating film and a movable electrode are provided on a conductor facing surface of the movable element. A driving electrode is arranged to displace the movable element, between a signal cutoff position and a signal passage position, whereby a high frequency signal transmitted through a transmission line is cut off or allowed to pass. The insulating film uses compressive stress to warp the movable element and the movable electrode in a direction of warping in a convex form toward the transmission line, and maintains this warping direction.
