| 20210407465 | SMART WINDOW DEVICE, IMAGE DISPLAY METHOD, AND RECORDING MEDIUM - A smart window device includes: a window that is transparent and displays an effect image; a request receiver that receives, from a user, a stop request or a change request for the display of the effect image; a data acquirer that acquires effect image data indicating the effect image reflecting a preference of the user learned based on a length of time from a start of displaying the effect image until the request receiver receives the stop request or the change request and a type of an object; and a controller that: when a sensor detects the object, determines the type of the object based on a detection result of the sensor, selects an effect image to be displayed on the window from among the effect image data, based on the type of the object determined, and causes the effect image to be displayed on the window. | 2021-12-30 |
| 20210407466 | DISPLAY SYSTEM - A display system includes an information acquisition device that acquires a position of a moving body, a display processing device that controls display of an image based on information acquired by the information acquisition device, a posture detection device that detects a posture variation of the moving body, a correction processing device that sets a first correction amount based on the posture variation, a gradient correction processing device that sets a second correction amount based on gradient information and a superimposition destination position at which the image is superimposed on an actual view in a display direction of the image, and a correction overlap amount setting unit that sets a correction overlap amount by which the first correction amount and the second correction amount overlap. The display processing device controls display of the image based on the first correction amount, the second correction amount, and the correction overlap amount. | 2021-12-30 |
| 20210407467 | FRONT BUFFER RENDERING FOR VARIABLE REFRESH RATE DISPLAY - A processing system reduces latency and improves predictability of a scan out position to support graphics processing unit (GPU) front buffer rendering with a variable refresh rate (VRR) display. The GPU detects whether front buffer rendering such as inking is occurring on a frame-by-frame basis. In order to maintain a safe distance from the current scan out position and achieve low latency to improve the user experience, the GPU increases the refresh rate of the VRR display to a low-latency (high-frequency) fixed refresh rate in response to detecting front buffer rendering. In some embodiments, the GPU decreases the refresh rate in response to detecting a static screen to save power. | 2021-12-30 |
| 20210407468 | FOLDABLE STRINGED INSTRUMENT - A foldable stringed instrument, for example in the form of a travel guitar that folds mid-neck to assume a reduced profile is described. The mid-neck folding is accomplished in a symmetrical manner about a three-part hinge located in the neck to configure the travel guitar into a reduced profile. The bridge assembly can be translated longitudinally relative to the head of the guitar to allow sufficient detensioning of the guitar strings to enable an upper portion of the neck to be folded away from a lower portion of the neck and/or body to assume a reduced profile. To deploy the travel guitar for playing, the upper portion of the neck is unfolded into alignment with the lower portion of the neck and/or body, and the bridge assembly translated longitudinally relative to the head and locked in position to allow the guitar to be tuned for playing. | 2021-12-30 |

| 20210407471 | MULTI FREQUENCY HARMONIZATION DEVICE - A device includes two or more units, with each unit connected to one or more other units, each of which includes a cap, a tube coupled to the cap and a reed coupled to the tube. Each tube generates at least one sound frequency and can also include harmonics of that single frequency. Airflow through the body oscillates the reed to produce an audible tone from the device. | 2021-12-30 |
| 20210407472 | HARMONY SYMBOL INPUT DEVICE AND METHOD USING DEDICATED CHORD INPUT UNIT - Disclosed are a harmony symbol input device and method using a dedicated chord input unit. The harmony symbol input device includes: a musical notation provider configured to visualize and provide a musical notation; a chord input unit provider configured to provide a dedicated chord input unit for inputting a harmony symbol in each harmony section of the musical notation; and a harmony symbol display part configured to repeat an operation that provides highlighting for a specific harmony section in a progression order of the musical notation and displays the harmony symbol received from the dedicated chord input unit in relation to the highlighting. | 2021-12-30 |
| 20210407473 | Musical Instrument Tuner - A frequency detection and display device includes a body having a vibratory portion configured for vibrating at a predetermined frequency. In this manner, the vibratory portion provides a visible indication corresponding to the predetermined frequency in response to vibration of an object, such as a stringed musical instrument, to which the frequency detection and display device is attached. | 2021-12-30 |
| 20210407474 | ELECTRONIC MUSICAL INSTRUMENT, SOUND PRODUCTION METHOD FOR ELECTRONIC MUSICAL INSTRUMENT, AND STORAGE MEDIUM - An electronic musical instrument includes: a plurality of performance elements that specify pitch data; a sound source that produces musical sounds; and a processor configured to perform the following: when a user performance of the plurality of performance elements satisfies a prescribed condition, instructing the sound source to produce a sound of a first timbre and a sound of a second timbre, both corresponding to a pitch data specified by the user performance; and when the user performance of the plurality of performance elements does not satisfy the prescribed condition, instructing the sound source to produce the sound of the first timbre corresponding to the pitch data specified by the user performance and not instructing the sound source to produce the sound of the second timbre. | 2021-12-30 |
