Abstract: A minimum IC operating voltage searching method includes acquiring a corner type of an IC, acquiring ring oscillator data of the IC, generating a first prediction voltage according to the corner type and the ring oscillator data by using a training model, generating a second prediction voltage according to the ring oscillator data by using a non-linear regression approach under an N-ordered polynomial, and generating a predicted minimum IC operating voltage according to the first prediction voltage and the second prediction voltage. N is a positive integer.

Abstract: A track light structure and an earth terminal fitting are disclosed. The track light structure includes a light body having a terminal block. The terminal block has two conductive terminals for connecting a live wire and a neutral wire. The terminal block has a socket communicating with the light body for insertion of a pin extending from the underside of a base of an earth terminal fitting, so that the pin is electrically connected to the light body. The base has a connecting portion and a conductive member electrically connected to the pin. The conductive member is configured to connect an earth wire. The earth terminal fitting is selectively connected to the terminal block through the connecting portion, thereby changing the track light to a three-terminal or two-terminal configuration.

Abstract: A real-time translation method for a mobile device is disclosed. In this method, a location of the mobile device is provided by a global positioning system (GPS). Then, an image is captured, and characters shown in the image are recognized in accordance with a language used in the location of the mobile device. Thereafter, the characters recognized are translated in accordance with a translation database. Then, a translation result of the characters recognized is displayed.

Abstract: A touch pad disposed in an electronic display device is provided. The touch pad includes a sliding region, a first virtual-key region and a second virtual-key region both adjacent to the sliding region, a first vibrator and a second vibrator. The sliding region are capable of sensing a dragging action, the first virtual-key region and the second virtual-key region are capable of sensing a pressing action, and the second virtual-key region corresponds to one side of the first virtual-key region. The first vibrator and the second vibrator are respectively disposed underneath the first virtual-key region and the second virtual-key region. When the first virtual-key region senses the pressing action, the first vibrator generates vibration. When the second virtual-key region senses the pressing action, the second vibrator generates vibration.

Abstract: A material holding and guiding device of automatic lathe has a base with one end provided with an arm frame and another end provided with a reciprocating set. A receiving and retaining set is mounted pivotally on the arm frame in a manner that the bottom of the receiving and retaining set is coupled with the reciprocating set. The receiving and retaining set has an inner annular body and an outer annular body. The inner annular body is axially provided with a through hole which is used to accommodate therein the material to be lathed and which is provided at each of two ends thereof with a ring sleeve. The motion of the reciprocating set causes the receiving and retaining set to make a swing of a predetermined angle so as to force the ring sleeves located at both ends of the through hole of the inner annular body to hold the material stably in a manner that the material is capable of turning synchronously with the inner annular body.
