Abstract: The present disclosure describes methods of differentiating cardiomyocyte progenitor cells and mature cardiomyocyte cells from pluripotent stem cells. The methods may include differentiating pluripotent stems cells on a substrate including (i) laminin-511 or 521 and (ii) laminin 221. The mature cardiomyocyte cells produced by the method may form a human heart muscle cell line for use in regenerative cardiology.

Abstract: Systems and methods for additive manufacturing of objects are disclosed. The system includes an object builder subsystem configured to additively manufacture an object in a powder bed, an object extraction subsystem configured to extract the object from the powder bed, and a depowdering subsystem configured to remove powder from the object while the object is gripped by the gripper assembly. The object extraction subsystem includes a gripper assembly comprising two or more gripper members that each include a perforated mesh structure.

Abstract: Apparatus and associated methods relate to fitting a virtual mask to a virtual face by first fitting a chin region of the virtual mask to the virtual face, then determining an virtual mask angle that maintains the fitted chin region while simultaneously fitting a nose-bridge region of the virtual mask to the virtual face, and then calculating a fit-quality metric corresponding to the fitted position. In an illustrative embodiment, the fitted chin region may include the high curvature menton region of the chin. In some examples, a virtual mask may be virtually pressed toward the virtual face using a predetermined force corresponding to a force of a mask securing device of a real mask corresponding to the virtual mask In an exemplary embodiment, the fitting of a virtual mask to a virtual face may advantageously yield a mask's fit quality in a brief amount of time.

Abstract: The present invention provides an air conditioner including a case, a compressor provided in the case, an evaporator, a condenser, an air duct system for heat ventilation and air refrigeration selectively, and piping members used thereof. The compressor is positioned at the bottom of the case, and the evaporator and condenser are mounted above the compressor in a side by side relationship. The said air duct system is provided in the top of the case. On one side of the said case there is a cooled air outlet for the evaporator and on the opposite side of the case there is a heated air outlet for condenser. The air conditioner is convenient to use and eliminates the need for a 4-way solenoid valve and repeated piping members, regularly used for transition between heating and cooling. Accordingly, the air conditioner provided by this invention is similar in structure to a single refrigeration unit, but has the dual function of both cooling and heating.

Abstract: An apparatus and a method for supporting a multimedia service which is capable of collecting opinions on a certain subject by receiving an opinion message in response to an opinion request message attached a plurality of images transmitted together with check widgets is provided. The method includes preparing at least two images, attaching at least two prepared images as thumbnail images to the multimedia service message for display at the same time, and transmitting the multimedia service message with the images. Accordingly, the user can make a decision, by negotiating with the counterpart user, on a subject such as a purchase of goods or a selection of foods.

Abstract: A portable device and a special character input method for the portable device. The portable device includes a controller for controlling display of more than one special character groups simultaneously, each special character group having a plurality of special characters, and a display for displaying the special character groups simultaneously under control of the controller. The special character input method classifies the special characters into a plurality of special character groups, displays the special character groups simultaneously, and presents a special character group in an enlarged pop-up window, thereby improving legibility of the characters and simplifying key manipulation for inputting the special characters.
