A portable information handling system rotationally couples housing portions with a variable torque hinge having a first axle that rotates with a first housing portion, a second axle that rotates with a second housing portion and a synchronizing gear assembly that translates rotation between the first and second axles. Variable torque is applied by selectively engaging and disengaging a coupler gear with the synchronizing gear assembly to apply and remove an increased torque that resists housing rotation. In one embodiment, the coupler gear is an idler gear of the synchronizing gear mechanism that selectively applies and removes an increase torque of the second axle to the first axle. The coupler gear slides in response to an actuator, such as an electro-permanent magnet acting on a ferromagnetic material with high and low magnetic attraction states.

A magnetic assembly structure has a main body and an inserting component. A first receiving slot of the main body receives a first magnetic component, and a second receiving slot of the main body penetrates a main body surface to form a main body opening on the main body surface. An engagement slot of the main body is disposed between the first receiving slot and the second receiving slot, communicated with the second receiving slot, and has a contacting surface being away from the main body surface with a distance. The receiving slot of the inserting component receives a second magnetic component. The inserting component is inserted into the second receiving slot via the main body opening, and the second magnetic component moves into the engagement slot. The magnetic assembly is assembled with a less force, has higher safety, and is hard to be disassembled without allowance or explanations.

An optical device includes a movable section including an optical section that deflects video light in accordance with the angle of incidence of the video light incident on a light incident surface and outputs the deflected video light and a holder that supports the optical section, an actuator that rotates the movable section around a first axis, an actuator that rotates the movable section around a second axis, a drive circuit that supplies the actuator with a first drive signal and the actuator with a second drive signal, and a sensor disposed in a position different from the positions on the first and second axes detects the position of the optical section, and the drive circuit adjusts the first and second drive signals in accordance with the position of the optical section detected with the sensor.

An actuator includes a support body, a movable body, a connection body, and a magnetic drive mechanism having a coil and a magnet for relatively moving the support body and the movable body. A winding part of the coil includes effective side portions, a first curved side portion connecting one side ends of the effective side portions, and a second curved side portion connecting the other side ends of the effective side portions.
