Abstract: An encoder includes circuitry and memory connected to the circuitry. The circuitry: derives an absolute value of a sum of horizontal gradient values; derives, as a first parameter, the total sum of the absolute values of horizontal gradient values; derives, as a second parameter, the total sum of the absolute values of vertical gradient values; derives a horizontal-related pixel difference value; derives, as a third parameter, the total sum of the absolute values of horizontal-related pixel difference values; derives a vertical-related pixel difference value; derives, as a fourth parameter, the total sum of the absolute values of vertical-related pixel difference values; and generates a prediction image using the first to fourth parameters.

Abstract: A three-dimensional serial focused intraoral digital tomosynthesis scanner includes a frame body, an image capturing module, a photosensitive member and an image processing module. The frame body includes a central axis and a light source seat which is moved along a scanning path and rotated around the central axis. The image capturing module is disposed on the light source seat and reciprocated along the scanning path. The image capturing module is configured to generate a light beam emitted from an outside to the patient's mouth. The photosensitive member is positioned in the patient's mouth. The light beam is emitted to the photosensitive member and moved along the scanning path corresponding to the photosensitive member so as to generate a plurality of two-dimensional optical images by the image capturing module. The image processing module calculates the two-dimensional optical images to generate a three-dimensional image.

Abstract: A latching module includes a beam structure and a locking element. The beam structure is installed on a cabinet and has a first groove and a second groove. The locking element includes a backside plate, a first engaging part and a second engaging part. After a covering plate is inserted into the first groove of the beam structure, the first engaging part of the locking element is inserted into the first groove and the backside plate of the locking element is sustained against the covering plate, and then the second engaging part of the locking element is locked into the second groove of the beam structure, so that the locking element is securely locked on the beam structure and the covering plate is securely fixed on the cabinet by the locking element.

Abstract: A volumetric phase transfer heat dissipating system includes a base, a cap and an atomizing member. The base includes a plurality of conducting members. The cap is engaged with the base to form a chamber. The conducting members are disposed in the chamber and extended toward the cap. The cap includes an inlet connecting portion for being connected to a fluid transmission tube and includes an outlet connecting portion for being connected to a vapor transmission tube. The atomizing member is sleeved to the inlet connecting portion and disposed between the fluid transmission tube and the chamber. A working fluid in the fluid transmission tube flows into the chamber via the atomizing member and forms liquid on inner walls of the chamber and outer walls of the conducting members, and the liquid is vaporized after absorbing heat and flows out via the vapor transmission tube.

Abstract: An audio signal processing method includes: controlling the volume of a digital audio signal according to a latest value of an adaptive gain value which is adjustable; detecting whether data carried by the digital audio signal satisfies a specific criterion and utilizing a pendulum counter to count a number of times the data carried by the digital audio signal satisfies the specific criterion; if the counter value of the pendulum counter reaches an upper bond, selectively decreasing the adaptive gain value according to a decrement to decrease the volume of the digital audio signal; and if the counter value of the pendulum counter reaches a lower bond, selectively increasing the adaptive gain value according to an increment to increase the volume of the digital audio signal, where the magnitude of the decrement and the magnitude of the increment are different from each other.
