Abstract: The disclosure provides an electronic device, including a circuit board, multiple semiconductor components, a first light reflecting structure, and a second light reflecting structure. The circuit board includes a substrate, and the substrate may have a first surface and at least one side surface. The multiple semiconductor components are disposed on the first surface. The first light reflecting structure is disposed on the first surface. The second light reflecting structure is disposed on the first surface and the at least one side surface.

Abstract: An on-board unit (OBU) coupled to an integrated starter generator (ISG) is disclosed. The ISG controls an engine. The OBU includes a communication unit and a processing unit. The communication unit receives a control signal from a mobile device. The processing unit is coupled to the communication unit for setting a setting state of the ISG according to the control signal, wherein the setting state is a start unallowable state or a start allowable state, and the ISG forbids the engine to be started or allows the engine to be started according to whether the setting state is the start unallowable state or the start allowable state. The control signal generates the setting state according to a start counter value, wherein the setting state is set to the start allowable state or the start unallowable state according to whether the start counter value is larger than a predetermined value.

Abstract: A socket for a microphone connector includes a body, said body having a fixing wall a round front wall formed to extend forward from said fixing wall, an annular wall formed to extend rearward from a rear surface of the fixing wall, plural terminal holes in the center of the body inside the annular wall. Lead terminals respectively have a lead connect end and a pinching end which is formed with two semicircular portions defining a center hollow provided with some elasticity for holding tightly terminals of a microphone connector with a large dimensions so as to keep stably the terminals and better transmitting signals between the socket and the microphone connector.

Abstract: A microphone connector includes a body, a terminal base received in the body, an elastic hook fixed on the body, a cable constrictor, a compress ring, a rotatable constrict ring, and a rear body. The rotatable constrict ring is threadably combined with the body, possible to be rotated to force the compress ring move forward and closely contact with a microphone so as to connect the connector tightly with the microphone with the elastic hook impossible to be pressed to prevent the microphone from separating from the connector. Further, the rear body engages with the body, having a cable constrictor formed in an outer end to constrict a cable.

Abstract: A connector marked with polarity includes a front body, a terminal base, a cable constrictor and a colored ring. The front body has a small diameter portion, a smooth annular surface portion, a male threaded rear end portion and a center lengthwise hole for the terminal base and the cable constrictor to fit therein. The rear body has female threads to engage the male threads of the front body. The cable constrictor constricts a cable placed in its interior. Then the colored ring is fitted around the small annular surface portion of the front body and constricted by the rear body after combined with the front body. The colored ring has various colors for marked polarity of the connector so as to discern the connector and the correct cable to match with.
