Provided are a webserver-based video content production system and method for printing a holographic stereogram photo. According to the webserver-based video content production system and method, an encoding process is performed on image data under a web environment to prevent data loss in a network communication process, and then the encoded image data is transmitted to a webserver. The webserver decodes the encoded image data and performs a second-half task (postprocessing) on the decoded image data using deep learning such that a high-quality hologram photo can be printed within a relatively short time without any unnecessary process.

Various example embodiments of the disclosure relate to an apparatus and method for providing a service based on context information in an electronic device. In this case, a portable electronic apparatus may include a communication module, an air pressure sensor configured to measure air pressure, a processor electrically coupled to the communication module and the air pressure sensor, and a memory electrically coupled to the processor. The memory may store instructions, when executed, for configuring the processor to determine whether the electronic device is located in a first geofence using the communication module, start monitoring of the air pressure by using the air pressure sensor at least in part on the determining that the electronic device is located in the first geofence, deactivate at least one part of the communication module when the monitored air pressure satisfies one or more of a first range and a first change rate, and re-activate the deactivated at least one part of the communication module when the monitored air pressure satisfies one or more of a second range and a second change rate after the at least one part of the communication module is deactivated. Other example embodiments may also be possible.

Method for providing service based on awareness and an electronic device thereof

A disclosed electronic device includes a processor, a memory, and a communication circuit that receives system information about at least one cell of a communication network from a base station. The processor is configured to determine whether the base station is a valid component of the communication network based on one or more cell allocation values included in the system information.

Method for determining validity of base station and electronic device supporting the same

The apparatus includes: a sensor module configured to detect sensor data corresponding to the motion of the apparatus, at least one processor that is electrically coupled with the sensor module and a non-transitory memory storing instructions executable by the processor to execute the method, including detecting the one or more pieces of sensor data by using the sensor module, detecting whether a motion pattern corresponding to the sensor data is stored in the memory, and generating a motion pattern based on at least some of the sensor data according to whether the motion pattern is stored in the memory.

Disclosed is a sewing arm mechanism of an embroidery machine. Within the sewing arm mechanism, there are provided a needle bar vertical drive unit and cloth pressing member vertical drive unit for vertically moving a needle bar and a cloth pressing member, respectively, by using the rotational driving force of an upper shaft. The sewing arm mechanism is configured in such a manner that the needle bar drive reaction force exerted on the upper shaft by the driving the needle bar vertical drive unit, and the cloth pressing member drive reaction force exerted on the upper shaft by the driving of the cloth pressing member vertical drive unit act in opposite directions of each other, whereby the magnitudes of the reaction forces exerted on the upper shaft can be cancelled with each other.

A presser foot drive structure of an embroidery machine, by which a vertically movable presser foot for preventing a sheet of cloth to be sewn from rising in a sewing operation is vertically moved inside a sewing head. The presser foot drive structure includes a presser foot drive holder, which is vertically slidable and is mounted on the outer circumference of a needle bar, which is vertically driven; a presser foot drive shaft, which is disposed parallel to the needle bar via the presser foot drive holder; and the presser foot, which is disposed at the lower end of the presser foot drive shaft and vertically reciprocates. It is possible to reduce the stroke of a presser foot so that it is smaller than that of a needle bar, enhance the supporting force for a needle bar, and reduce the shaking of a presser foot.

Presser foot drive structure for embroidery machine

An embroidery machine includes a sewing arm having an upper shaft for providing a driving force, a needle bar support case, which is assembled to a front portion of the sewing arm so as to be laterally movable, a needle bar provided in a needle bar support case, the needle bar having a needle at a lower end thereof and vertically carrying the needle using a rotation driving force of the upper shaft, and a presser foot, which is provided in the needle bar support case so as to be vertically movable, characterized in that each of the needle bar and the presser foot is operated by an individual drive mechanism. The presser foot is separately driven by its own drive source, independent of the drive source of the needle bar.

Disclosed are a rack and pinion type power transmission and a driving apparatus of an embroidery frame of an embroidery machine having the same. The gear teeth, which are engaged with the engaging member connected to the power source, are formed in the lower side of the a single movable frame, to which the embroidery frame is fixed, so as to directly move the movable frame, so that uniform driving force is transmitted to the embroidery frame during the movements of the embroidery frame. Thus, the high reliable and steady movement is performed. The driving apparatus includes any one of the X- and Y-directional movement mechanisms. The mechanism includes a fixed frame installed to a beam-body of the sewing machine, a movable frame movably installed on the fixed frame and having gear teeth, and a movable frame movement mechanism engaged with the gear teeth to reciprocate the movable frame.

A self illumination circuit of a hand-held remote control device and self illumination method make it easy to find and operate the remote control device when the remote control device is located in a dark environment. The circuit includes an illuminance sensing section, a contact sensing section, a key sensing section, a control section, a position indicating section, a key illuminating section, and a counter. If the illuminance sensing section senses illuminance of environment and transfers an illuminance sensing signal to the control section, the position indicating section indicates position of the remote control device according a position indicating signal from the control section. Upon receiving signals from the contact sensing section, the key sensing section, and the counter, the control section lights up, twinkles and puts out the key illuminating section.

In a karaoke system capable of scoring a singing of singer on an accompaniment thereof, when a voice signal of the singer is inputted, an energy detector generates a first basic frequency signal with respect to a voice signal section and inputs the first basic frequency signal to a comparator. And then, an audio signal in the voice signal section is inputted to the comparator as a second basic frequency signal. The comparator compares the first and second basic frequency signals with each other and calculates a difference value therebetween, and then inputs it to a microprocessor. The microprocessor outputs a signal for scoring the singing of the singer on the basis of the difference value.
