Abstract: Systems, apparatus, and methods for providing haptic feedback at electronic user devices are disclosed. An example apparatus includes processor circuitry to perform operations to instantiate touch response area detection circuitry to identify a touch response area of a display screen; haptic feedback analysis circuitry to detect that a location of a touch on the display screen is within the touch response area and output an instruction to cause a haptic feedback response; and haptic feedback control circuitry to, in response to the instruction, cause a haptic feedback actuator to generate the haptic feedback response based on the location of the touch and a property of the haptic feedback response.

Abstract: A heat sink apparatus for heat dissipation for a CPU includes a fan, a heat sink module and a latch. The fan has at least one attachment hole. The heat sink module is mounted onto the CPU, and is itself a metal heat conduction column having, a plurality of arc-shaped cooling fins radiating from the edge of the metal heat conduction column and a plurality of mounting holes positioned at the ends of the arc-shaped cooling fins. In addition, each mounting hole corresponds to a respective attachment hole. The latch comprises at least a latch arm, a plurality of openings and at least one latch hole. The latch arm is secured to the flange at the side of the CPU socket. Each of the openings corresponds to a mounting hole on the arc-shaped cooling fins of the heat sink module and the attachment holes on the fan.
