A resin multilayer substrate includes a multilayer body including resin base-material layers in a thickness direction, a side-surface conductor on at least a side surface of the multilayer body and made of a metallic material with a coefficient of thermal expansion whose difference from a coefficient of thermal expansion of the resin base-material layers in a plane direction is smaller than a difference from a coefficient of thermal expansion of the resin base-material layers in the thickness direction, a circuit component in the multilayer body and defining a circuit, and inner conductors in the multilayer body, located between the side-surface conductor and the circuit component along the side-surface conductor, and at least partially overlapping each other when viewed in the thickness direction, each of the inner conductors being one of a dummy conductor and a ground conductor.

A lighting element is disclosed that provides a projection of light forming a substantially uniform bright light on a surface a known distance from the lighting element. The lighting elements includes a dome lens that is removably positioned on a light source, such that the light source is retained at a location within a focal length of a projection lens and at or within a focal length of the dome lens. The dome lens magnifies the light outputted by the light source, such that the projected light is brighter than the light generated by the light source.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

A fixing device includes a circuit board, an insertion slot, and a fixing bracket. The circuit board has a peripheral recess, and the insertion slot is disposed on the circuit board. The fixing bracket is fixed in the peripheral recess, and the fixing bracket has a board, two lateral arms, and two guiding rails. The two lateral arms are connected to two corresponding sides of the board, and the two lateral arms are integrally formed from the board. In addition, the two guiding rails are respectively disposed at the two lateral arms, in which the two guiding rails extend towards the insertion slot.

The present disclosure relates to a printed circuit and an electronic device including the same. The printed circuit board includes a first substrate having a through portion, a second substrate disposed in the through portion of the first substrate, and in which at least a portion of a side surface thereof is surrounded by the first substrate, and a flexible substrate disposed in the through portion of the first substrate and connecting the first and second substrates.

A temperature measuring apparatus with improved accuracy is provided. The temperature measuring apparatus comprises a test substrate having a thermal conductivity, a circuit board layer laminated on the test substrate and including a plurality of through holes exposing a top surface of the test substrate, bonding agent disposed in the plurality of through holes and having a thermal conductivity, and a plurality of sensors disposed on the bonding agent and for measuring a temperature.

A display device includes a substrate including a display part having a first width in a first direction and a pad part protruding from the display part in a second direction crossing the first direction and having a second width in the first direction, the second width being smaller than the first width, and a printed circuit board having a concave-convex shape towards the substrate. As the printed circuit board has the concave-convex shape, a dead space of the display device is reduced.

A capsule core and a capsule endoscope are provided. The capsule core includes a printed circuit board module, connecting structures and functional units. The printed circuit board module includes more than more printed circuit boards connected through flexible circuit boards and spaced apart. The connecting structures connect adjacent printed circuit boards. The functional units are mounted on the printed circuit boards or the connecting structures, and at least part of the functional units communicates with the printed circuit boards.

A driving system for moving several optical elements is provided, including a first module, a second module and a third module. The first, second and third modules respectively have a first, second and third terminal electrically connected an external circuit. The first terminal is on a first side of the first module, the second terminal is on a second side of the second module, and the third terminal is on a third side of the third module. Specifically, the first, second, and third terminals are located on the same side of the driving system.

A seat ventilation blower may include a first housing; a second housing coupled and assembled to the first housing; an impeller inserted inside the first housing or the second housing, the impeller configured to rotate; and a circuit board body having a motor assembly coupled to the impeller to rotate the impeller wherein the circuit board body is configured to control operation of the motor assembly and installed in the housing when the first and second housings are coupled and assembled together.
