Abstract: An electric motor in which at least one of the rotor and the stator has, an asymmetric design is disclosed. The electric motor is divided into a number of segments, where each segment has an equal number of windings and an equal number of poles. The physical construction of each pole within a segment is identical and the number of turns of each winding within a segment is identical. The asymmetry is formed by varying the physical construction of the either the rotor or the stator within one segment from the corresponding construction of the rotor or stator in the other segments. The asymmetries are designed to improve one or more operating characteristics such as sensorless performance, torque ripple, or cogging torque in the motor.

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.

In general, the monitoring system includes features designed to detect one or more hot spots within a dim or dark environment, determine the location of the hot spot within the enclosure, determine a temperature range of the hot spot, and/or notify (e.g., alarm or alert) an operator upon detection of the hot spot. The monitoring system may include one or more temperature sensitive elements configured to determine the heating of potential hot spots within the electrical enclosure. Further, the foregoing features may be designed to allow one or more electrical enclosures to remotely communicate with computer equipment (e.g., workstation or general purpose computers) over a wireless network.
