Abstract: The present invention relates to an epoxy resin composition for molding, and a semiconductor device sealed using the same or a vehicle part molded using the same.

Abstract: A lens moving apparatus can include a cover member comprising an upper plate and a lateral plate extending from the upper plate, a bobbin disposed in the cover member, a coil disposed on the bobbin, a driving magnet disposed between the coil and the lateral plate of the cover member, and a sensing magnet disposed on the bobbin. Also, the lens moving apparatus can further include a circuit board disposed on the lateral plate of the cover member, and a position sensor disposed on the circuit board and configured to sense the sensing magnet, in which a part of the coil is disposed between the sensing magnet and the circuit board.

Abstract: Embodiments provide a lens moving apparatus including a first magnet, a housing, a bobbin, around which a coil is wound and which moves in a first direction in the housing, an upper elastic member disposed on upper surfaces of the bobbin and the housing, a lower elastic member disposed under lower surfaces of the bobbin and the housing, and a damping member disposed between the upper or lower elastic member and the bobbin.

Abstract: Embodiments provide a lens moving apparatus including housing to support a driving magnet, a bobbin provided at an outer circumferential surface thereof with a coil located inside the driving magnet, the bobbin being moved in a first direction parallel to an optical axis within the housing via electromagnetic interaction between the driving magnet and the coil, a lower elastic member to connect a lower portion of the housing and a lower portion of the bobbin to each other, both ends of the coil being electrically connected to the lower elastic member, the lower elastic member having a first terminal electrically connected to an external power source so as to supply external power to the ends of the coil, and a printed circuit board provided at one side surface of the housing, the printed circuit board having a second terminal electrically connected to the external power source.

Abstract: Radio frequency (RF)-based ranging and imaging in a wireless communications circuit, particularly for a wireless communications system (WCS) is provided. The wireless communications circuit includes an antenna circuit configured to radiate an RF probing signal in a number of directions in a wireless communications cell and receives a number of RF reflection signals corresponding to the RF probing signal. A radar signal processing (RSP) circuit is configured to process the RF reflection signals to detect an obstacle(s) in the wireless communications cell and generate a surrounding image that includes the detected obstacle(s). By generating the surrounding image of the wireless communications cell, it may be possible to detect the obstacle(s) that was not accounted for in an initial deployment design. As a result, it may be possible to adjust a remote unit(s) incorporating the wireless communications circuit to improve RF coverage, throughput, and/or capacity in the wireless communications cell.

Abstract: A toothbrush for a pet dog is disclosed, in which a groove is longitudinally formed in a center of a head in a direction of a handle, and a cushion material is provided in a surrounding surface, a lower surface and the groove. When a pet dog bites a toothbrush with teeth during a tooth brushing, it is possible to prevent teeth from fracture while preventing a lot of pain occurring when teeth collide with a hard toothbrush. Toothbrush hairs planted in a head are shaped depending on a tooth shape of a pet dog, so it is possible to reliably brush off plague attached on the upper side of a cervical ridge of premolars and molars of a pet dog without applying over stimulation on the gum.

Abstract: A method for conserving power in an apparatus is disclosed. The method generally includes the steps of (A) disabling a subset of a plurality of debug operations using a clock signal at a first frequency while in a normal mode, (B) performing a plurality of debug operations using the clock signal at a second frequency while in a debug mode, wherein the first frequency is slower than the second frequency to conserve power, and (C) adjusting the clock signal to one of the first frequency and the second frequency in response to receiving a command generated external to the apparatus to transition to a respective one of the normal mode and the debug mode.
