Abstract: A motor assembly includes a stator, a rotor rotatable about an axis, and a housing at least in part defining a motor chamber. The stator and the rotor at least in part are received within the motor chamber. The housing includes a first housing portion and a second housing portion. The housing portions engage one another along an interface. The interface restricts ingress of contaminants therethrough into the motor chamber. The housing portions cooperatively define a nested portion that at least in part defines the interface. The nested portion includes an arcuately extending projection and an arcuately extending receiver. The receiver defines an arcuately extending receiving channel. The projection is at least in part received within the receiving channel.

Abstract: An induction motor assembly includes a motor. The motor includes a rotor rotatable about a rotor axis, and a stator at least substantially circumscribing the rotor. The stator includes a generally toroidal core. The core includes a generally circumferential yoke and a plurality of arcuately spaced apart teeth extending radially inwardly from the yoke. The tooth length is at least three (3) times the yoke thickness.

Abstract: An optical communication system for transmitting multiple optical beams, each at a different wavelength is disclosed. The optical communication system includes a laser array having multiple laser transmitters transmitting multiple optical beams, each at a different wavelength. The optical communication system further includes a diffraction grating optically coupled to the laser array, the diffraction grating diffracting each of the optical beams at a substantially equal diffraction angle to form a combined optical beam. The combined beam is then focused into an optical communication media.

Abstract: A photonic device including an array of lasers providing light to an array of electro-absorption modulators, both on a common substrate. In some embodiments the lasers are in a closely spaced array and lase at different wavelengths, providing with associated electro-absorption modulators a compact wavelength selectable laser.

Abstract: One or more single mode waveguide devices are fiber coupled such that signals to an optical element affect the coupling of the waveguide device to one or more on chip modulators and to an optical fiber. The optical element or additional optical elements are controlled to adjust the coupling of the waveguide device to an on chip modulator and to an optical fiber.
