Abstract: A high frequency ultrasonic transducer may include a plurality of adjacent ultrasonic transducer elements. The adjacent transducer elements may be sized and configured so as to resonate at a frequency that is at least 15 MHz. The adjacent transducer elements may collectively form an aperture that is substantially convex along a lateral dimension spanning the cascaded width of the adjacent transducer elements. The aperture may be substantially concave along an elevation spanning the height of each of the transducer elements. The ultrasonic transducer and an associated transmitter system may be configured so as to enable ultrasound that is radiated from the plurality of the transducer elements to be focused on and to scan across locations that are no more than 30 millimeters from the aperture and that span across a field of view of at least 50 degrees without movement of the ultrasonic transducer or tissue during the scanning.

Abstract: A washing machine and a method of controlling the washing machine are provided. In the washing machine and the method of controlling the washing machine, a liquid detergent is automatically supplied into a washing tub, thereby improving user convenience. In addition, in the washing machine and the method of controlling the washing machine, a liquid detergent is supplied into the washing tub by water circulated by a circulation unit. Thus, no liquid detergent remains in a liquid detergent supply path, and the liquid detergent supply path can be prevented from being blocked due to the solidification of a liquid detergent.

Abstract: Disclosed is the washing/drying machine including a fragrance supplying means for supplying fragrance, and a heat supplying means for supplying heat to promote evaporation of a fragrance source stored in the fragrance supplying means. The washing/drying machine uses heat supplied by the heat supplying means so as to promote evaporation of a fragrance source in the fragrance supplying means, thereby increasing efficiency in fragrance supply.

Abstract: It is an object of the present invention to provide a hollow fiber membrane module which maximizes the efficiency of removing scale-like contaminants generated at the water treatment using hollow fiber membranes, and a method of manufacturing the same. The hollow fiber membrane module includes hollow fiber membranes for making water treatment due to the pressure difference, and a collector fixing the hollow fiber membranes in bundle. A treated-water tube is extended to the inside of the collector, and communicated with the inner passage of the hollow fiber membranes to deliver the water treated through the hollow fiber membranes. A diffuser is installed at the collector to diffuse bubbles to the hollow fiber membranes. An air tube is extended to the collector, and connected to the diffuser to feed air. Dividers are installed over the collector to partition the hollow fiber membranes into a plurality of bundles.

Abstract: An exercise machine is provided. The exercise machine includes a support defining a longitudinal direction and a transverse direction, a first motion unit coupled to the support to provide a combined translational and pivotal movement of the first motion unit in the transverse direction, a second motion unit coupled to the first motion unit to provide one of a translational movement and a pivotal movement of the second motion unit in the longitudinal direction, and a driving source configured to impart movement to the first and second motion units.

Abstract: For noninvasive treatment of tissue using high intensity focused ultrasound, composite imaging and therapy acoustic techniques are described. Embodiments include an integrated multi-functional confocal array and a strategy to perform both imaging and therapy simultaneously with this array by using coded excitation techniques with/without a notch filter. An exemplary array embodiment includes a triple-row phased array with one array in the center row for imaging and two arrays in the outer rows for therapy. Different types of piezoelectric materials and stack configurations may be employed to maximize the respective therapy and imaging functionalities. Reflected therapeutic signals that would otherwise corrupt the quality of imaging signals received by the center-row array can be mitigated or removed by use of the coding and/or a notch filter when B-mode images are formed during therapy.

Abstract: Provided is a method of dynamically reallocating a thread stack in a multi-threaded operating system, and more particularly, a method of dynamically allocating a thread stack of a multi-threaded operating system in an embedded system for wireless sensor nodes. The method includes the steps of: measuring sizes of data and non-data sections of a stack with respect to each thread; determining a new size of the non-data section of each stack based on the size of the data section of the stack measured with respect to each thread; and adjusting the size of the non-data section of each stack to the determined new size. According to the method, even without the source code analysis, an amount of memory spaces to be used can be reduced compared to that of a conventional static stack allocation method.

Abstract: Disclosed is a washing machine, which can automatically supply a liquid detergent into a washing tub and automatically clean inner flow passages through which the liquid detergent has flown with a cleaning solution. A liquid detergent supply mechanism supplies at least one kind of liquid detergent to the washing tub, and the inner flow passages of the liquid detergent supply mechanism through which the liquid detergent has flown are cleaned with the cleaning solution supplied from outside.

Abstract: Disclosed is a washing machine, which prevents solidification of liquid detergent by rapidly recovering the liquid detergent left in a liquid detergent supply passage and a liquid detergent supply pump by forming a negative pressure differential by use of the liquid detergent supply pump for a set period of time after the supply of liquid detergent is finished.

Abstract: A washing machine is provided. The washing machine includes a support frame, which supports the main housing of the washing machine, and a liquid detergent container, which is disposed in the support frame and contains a liquid detergent therein. Therefore, the washing machine can improve the efficiency of the use of a liquid detergent.

Abstract: Provided is a method of allocating a stack in a multi-threaded sensor operating system environment. The method dynamically allocates as much stack space as is required by a thread, thereby enabling efficient use of stack space. The method includes the steps of: whenever a function is called while a thread is performing an operation, dynamically allocating a stack space to be used by the called function; and when execution of the function is finished, returning the allocated stack space.

Abstract: Planar waves are transmitted to a target object with an angle of wave propagation corresponding to a center position of a receive subaperture. The echo signals reflected from the target object are received by the receive subaperture, stored in a receive pattern memory and dynamic-focused. The dynamic-focused signals are then combined to form at least one beam pattern to produce an ultrasound image.
