The problem of charge leakage in the AC compensation filter for the error amplifier of a pulse width modulation (PWM)-based DC—DC converter is effectively obviated by controllably sampling and storing the voltage across the AC compensation filter, in response to a transition of the operation of a DC power supply from run or active mode to quiescent or sleep mode. The sampled voltage is retained as a compensation voltage throughout the quiescent mode, so that it will be immediately available to the PWM circuitry at the termination of the quiescent interval. This serves to ensure a relatively smooth (low noise) power supply switch-over during a subsequent transition from quiescent to active mode.

An envelope tracking power amplifier system time-aligns a supply voltage to an input signal to a power amplifier. The power supply operates in a static mode for low amplitude input signals and operates in a dynamic mode for high amplitude input signals. In the static mode, the power supply produces a substantially constant supply voltage independent of the amplitude of the input signal. In the dynamic mode the power supply produces a dynamically varying envelope tracking supply voltage based on the amplitude of the input signal. A first delay is determined based on portions of the input and output signals captured during static operation of the power supply and a second delay is determined based on portions of the input and output signals captured during dynamic operation. A delay mismatch is estimated based on a difference between the first and second delays.

A low-vision viewer magnifies the face-up source material in the visual field of a camera and displays the magnified image on a VDU or other display means. In a static mode, the camera captures and stores a high-resolution image of the source material. This high-resolution image can be manipulated and subsequently displayed on the VDU. In a live mode, the camera captures a low resolution image of the source material or a high resolution image of a section of the source material to provide a high frame rate for full motion video. In the live capture mode, the low-vision user can move their view around the source material and zoom in on a desired section of interest. The same camera is used in either static or live modes.

A pair of multi-frequency ultrasound transducer surround a fluid flow and are configured to operate under computer control in both a mono-static and a bi-static mode at each of the multiple frequencies. In the mono-static mode, pulsed wideband Doppler shift measurements provide the velocity profile across the fluid flow which can be combined with measured pressure drops to determine the rheogram—a plot of shear stress versus shear rate. Velocity profile data from each frequency can be combined to form a composite velocity profile. In the bi-static mode, transmission data is collected that improves the accuracy and robustness of the velocity profile and provides supplemental material property information. The system is configured for automated operation for a wide variety of fluid types and can be reconfigured and / or monitored remotely.

A core-strengthening exercise apparatus is comprised generally of three primary components, namely a pair of identically shaped and configured swing arms each of which is pivotally mounted at or proximate to its midpoint to a substantially C-shaped transverse bar member. The apparatus has two general modes of use. In a first mode of use, referred to as the “static mode”, the subject apparatus may be oriented such that its swing arms rest on the floor with the bar member extending therebetween a distance above the floor to provide a stable gripping surface over which a plurality of exercises may be performed. In a second mode of use, referred to as the “dynamic mode”, the apparatus is flipped over such that only the bar member is in contact with the floor supporting the swing arms there above. In this mode, the user supports his or her upper body in the plank position over the apparatus by grasping either end of each swing arm and resting his or her forearms along the longitudinal axis thereof. The unique curvature and configuration of the bar member creates an inherently unstable interface between the user and the floor permitting side-to-side or back-to-front rocking motions, pivoting motions about a vertical axis, or combinations thereof, all requiring control over core muscles to prevent loss of balance.

A tensioning device has a tension arm mounted on a base. A pulley is mounted on the tension arm for engaging a looped belt. By changing mounting bushings, one can select either a static mode wherein the tension arm is held stationary relative to the base, or a dynamic mode wherein, in response to a changing force applied between the pulley and the belt (due to vibrations or load changes, for example), the tension arm moves relative to the base in such a manner as to maintain the force substantially constant. Several such devices can be employed in a system for controlling the tension of a looped belt, one or more of the devices being in the static mode and one or more being in the dynamic mode. Several such systems can be employed in a complex machine such as a photocopier or medical apparatus for controlling the tension in a number of different belts.

A method of motion estimation for video encoding constructs a binary pyramid structure having three binary layers. A state update module registers and updates repeat occurrence of final motion vectors and a static-state checking module determines if the method is in a static mode or a normal mode based on the repeat occurrence. In a normal mode, the first binary layer is searched within a ±3 pixel refinement window to determine a first level motion vector. In the second binary layer, a search range is computed based on six motion vector candidates. By checking every point within in the search range, a second binary layer search generates a second level motion vector. Finally, a third binary layer search within a ±2 pixel refinement window generates a final motion vector according to the second level motion vector. In a static mode, a fine tuning module performs search within a ±1 pixel refinement window and generates a final motion vector.

Detection of intravascular plaque in OCT images is carried out by obtaining images of vascular tissue from a vascular component by OCT either in a static mode of a single image or in a dynamic mode where the images are obtained by scanning. The method acts by dividing the OCT image into different regular regions, calculating different texture features for each of the above regions with a reduced set of less than a full set of the 26 Haralick textural features, using a clustering algorithm to segment the image defined by its texture features calculated above into different regions and transforming the segmented image back from its representation using texture features to its space-domain representation. The method uses three or four texture features where the reduced sets can be f1, f 2, and f14 (ASM at 0°, Inertia at 0° and ASM at 90°).

Multicarrier modulated communications, involving a transmitting modem (30; 30′) and a receiving modem (40; 40′) that operate according to normal operating mode and a low-power, quiescent, mode, are disclosed. In the quiescent mode, transmitter power is saved by scaling down the amplitude of the transmitted symbols in each frame by a scaling factor (A), and transmitting multiple instances of the frames in sequence. On receipt, the repeated frames are summed, and the summed amplitudes scaled to account for the repetition factor (M) and the scaling factor (A), to recover the transmitted information. If the repetition factor (M) is greater than or equal to the square of the scaling factor (A), the signal-to-noise ratio in quiescent mode is at least as high as that in normal operation. The repeating, scaling, and summing may all be performed in the frequency domain or in the time domain, as desired.
