Abstract: An adjustable light source device for a stereoscopic surgical microscope has a circuit board and multiple light sources. The circuit board is mounted in an outer casing of the stereoscopic surgical microscope and is electrically connected to a host computer of the stereoscopic surgical microscope. The light sources are electrically mounted on the circuit board at spaced intervals around two objective lenses of the stereoscopic surgical microscope and extend out of the outer casing. Each one of the light sources has a wavelength different from wavelengths of the other light sources and is controlled to emit light by an operating set of the stereoscopic surgical microscope via a program processing interface of the host computer sending signals to the circuit board. The adjustable light source device can emit lights with different wavelengths to enable the stereoscopic surgical microscope to capture clearer images for various surgical divisions.

Abstract: An apparatus includes a switch module that selectively turns on a switch to connect an input power conductor connected to a voltage source to a motor in a sequence. The switch for each phase is turned on for a portion of a cycle of a fundamental frequency of the voltage source. A source phase module determines a phase of the AC voltage source, a back-EMF phase module determines a phase of a back-EMF of the motor, and a torque module determines when a phase difference between the phase of the AC voltage source and the phase of the back-EMF is within a phase range indicative of a positive motor torque. A pulse module enables the switches in response to the phase difference having a phase within the phase range and disables the switches in response to the phase difference having a phase not in the phase range.
