A portable information handling system is assembled and disassembled by a keystone assembly that couples at an upper surface of the portable housing to overlap a keyboard assembly that covers processing components disposed in the portable housing. The keyboard assembly includes a membrane having a first portion with key press detection sensors contiguous to a second portion with a touch detection sensor that supports a touchpad. In one embodiment, the membrane integrates a printed circuit board that couples a key matrix controller and a touch detection controller interfaced with a communications hub, such as a USB hub, to communicate key and touchpad inputs to a motherboard through a flexible connector portion of the membrane.

A Totem Pole PFC circuit includes at least one fast-switching leg, a slow-switching leg, and a control unit. Each fast-switching leg includes a fast-switching upper switch and a fast-switching lower switch. The slow-switching leg is coupled in parallel to the at least one fast-switching leg, and the slow-switching leg includes a slow-switching upper switch and a slow-switching lower switch. The control unit receives an AC voltage with a phase angle, and the control unit includes a current detection loop, a voltage detection loop, and a control loop. The control loop generates a second control signal assembly to respectively control the slow-switching upper switch and the slow-switching lower switch. The control loop controls the second control signal assembly to follow the phase angle, and dynamically adjusts a duty cycle of the second control signal assembly to turn on or turn off the slow-switching upper switch and the slow-switching lower switch.

A portable information handling system includes a touch function row between a keyboard and a display that accepts touches or proximity detection at plural locations to initiate an on-screen-display user interface for a selected of plural functions based upon a touch location. Haptic feedback to touch function row inputs is provided by a haptic device coupled directly to a bottom surface of the touch function row, such as with an adhesive. The haptic device couples to a housing cover portion with a brace that integrates a resilient member, such as a spring, to dampen vibration from a haptic vibration source to the housing cover portion.

An induction cooker includes a rectifying device, a first energy-storage device, a switch device, a second energy-storage device, a heating device and a control device. The capacitance of the second energy-storage device is greater than the capacitance of the first energy-storage device. When the induction cooker is just starting, the control device controls the switch device to be turned off, such that the heating device generates an output current according to an energy of the first energy-storage device. The control device determines whether a pot is on the heating device according to a change state of the output current. When the pot is on the heating device, the control device controls the switch device to be turned on, such that the first and second energy-storage devices are coupled, and the heating device heats the pot according to energies of the first and second energy-storage devices.
