Abstract: A card edge connector for transmitting signal and power simultaneously. The connector has two or more types of conductors held by a housing. First and second types of conductors are configured for transmitting signal and power, respectively. The housing has a slot for receiving a mating component. The housing has first and second types of grooves for holding the first and second types of conductors, respectively, such that the conductors can sustain a similar amount of force generated when mating with the mating component. The conductors have mating ends with contact portions curving into the slot and mounting ends opposite the mating ends and extending out of the housing. The mating and mounting ends of the first and second types of conductors are configured such that they can be deflected by the mating component simultaneously and mounted to a printed circuit board using a same process.

Abstract: Various techniques for implementing resistive temperature sensors that rely on the resistors' temperature sensitivity to provide temperature sensing are disclosed. Temperature sensitive resistors may be implemented in a resistor stack in combination with a resistor stack of resistors that are relatively temperature indifferent. Various temperature sensor circuits implementing these temperature sensitive resistors are also disclosed. A temperature sensor circuit may implement the temperature sensitive resistors along with the resistors that are relatively stable with temperature to output a voltage signal that is indicative of the temperature sensed by the circuit. In some instances, the signal from the temperature sensitive resistors is increased through the use of a feedback resistor loop.

The driver IC is configured to perform a white balance compensation on image data collected by the photosensitive element of the display device according to a deviation between the first white balance imaging parameter the second white balance imaging parameter.

Abstract: A motion trail update method includes: receiving first pose information for a target device transmitted by a first sensor at a first frequency; selecting second pose information meeting a preset condition from a second pose information queue as target second pose information to obtain a target second pose information set; performing trail smoothing on adjacent pose information and the first pose information by using the target second pose information set to obtain a smooth pose information sequence; performing mapping on each piece of smooth pose information in the smooth pose information sequence to obtain a target pose information sequence of a virtual object, corresponding to the target device, in a virtual space; and updating a motion trail of the virtual object in the virtual space.

Abstract: A card edge connector for high bandwidth transmission. The connector may include a housing having a groove between two walls. The walls may include slots holding terminals of the connector. The terminals of the connector may each include a mating contact portion, a mounting contact portion opposite the mating contact portion, a bearing portion extending from the mounting contact portion and fixed in the housing, and a beam extending from the bearing portion. The beams may be configured to flex when the mating contact portions make contact with pads on a card. The terminals may each include a curved transition portion between the mating contact portion and the beam so as to prevent the beam from touching the card. The housing may include holes through the walls between mating contact portions of selected adjacent terminals. Such a configuration reduces impedance mismatch at the mating interface and therefore improve signal integrity.

Abstract: A miniaturized paddle card assembly that provides high-speed, high-performance transmission. The paddle card has two or more rows of contact pads for mating with complementary conductors, two or more rows of terminals for cable termination, and alternating dielectric layers and metal layers. The two or more rows of terminals are disposed on respective metal layers. Such a configuration enables conductive traces electrically connecting corresponding contact pads and terminals to be substantially straight, and therefore reduces the lengths of the conductive traces. It is also reduced that the size of the paddle card in both a lateral direction parallel to the rows and a longitudinal direction perpendicular to the lateral direction, without changing the thickness of the paddle card. With the paddle card assembly provided herein, the integrity of the signals transmitted therethrough can be maintained and/or improved at higher speed.

A housing of the electrical connector holding conductive elements is coupled to the plate of the frame such that a top surface of the housing is substantially flush with top surfaces of the two platforms. The platforms of the frame have threaded holes extending therethrough such that screws can be inserted to hold one of the two platforms of the electrical connector to a first circuit board and the other one of the two platforms of the electrical connector to a second circuit board that is substantially edge aligned to the first circuit board. Such a configuration enables connecting circuit boards of various thicknesses in a coplanar manner.
