摘要： A braking system for an elevator includes an electromagnetic brake operably connected to an elevator car. A control circuit is operably connected to the electromagnetic brake and includes a switching mechanism to selectively modify a rate of engagement of the electromagnetic brake to selectively modify deceleration of the elevator car. A method of engaging an electromagnetic brake for an elevator system includes detecting one or more operational characteristics of the elevator system and selecting a first position or a second position of a switching mechanism disposed at a brake control circuit depending on the sensed operational characteristics. Electrical current is directed through one or more components of the brake control circuit, depending on the position of the switching mechanism, to determine a rate of engagement of the electromagnetic brake. A flow of electrical current through the brake control circuit is stopped, thereby causing engagement of the electromagnetic brake.

摘要： A system and a method are provided for damping vertical oscillations of an elevator car hovering at an elevator landing. The system includes a sensor, a controller and an elevator machine connected to a traction sheave. The sensor is adapted to provide a sensor signal indicative of rotation of the traction sheave, wherein the rotation of the traction sheave corresponds to the vertical oscillations of the hovering elevator car. The controller is adapted to provide a control signal based on the sensor signal. The elevator machine is adapted to reduce the vertical oscillations of the hovering elevator car by controlling the rotation of the traction sheave based on the control signal.

摘要： A hybrid optic includes a folded optical element with an outer reflective surface, an output surface, and a hollow core comprising a sidewall, a core output surface, and a core input opening through which light emitted by a light source enters the hollow core. A reflector element, coupled to the folded optical element, receives light from the light source, reflects a portion of the light into the hollow core and directly transmits the remaining portion of the light into the hollow core. To reduce the appearance of non-uniformities in the output light, the reflector element is diffuse and white, portions of the folded optical element are diffusely reflective, and/or a glare control diffuser is disposed on the output surface to disperse light transmitted through the core output surface of the hollow core. In this manner, the light coupling efficiency of the hybrid optic is enhanced without producing structured light.

摘要： An elevator system includes an elevator car, a motor, and traction sheave operably connected to the motor to drive rotation of the traction sheave. A belt is operably connected to the elevator car and in frictional contact with the traction sheave to urge movement of the elevator car. One or more deflector sheaves are located between the traction sheave and the elevator car over which the belt is routed to guide the belt to the elevator car. The one or more deflector sheaves include an outer sheave surface having a distance from a sheave axis that varies along a width of the traction sheave. The outer surface includes a first portion having a first coefficient of friction and a second portion having a second coefficient of friction less than the first coefficient of friction, the first portion guiding an elevator belt toward a lateral center of the outer surface.

摘要： A recessed lighting system includes multiple components formed from a polymer to reduce the number of components in the system, lower the cost of manufacture, and simplify the installation of the recessed lighting system. In one example, a recessed lighting system includes a housing formed from a polymer, a hanger bar assembly, a light module, and a trim. A yoke may be installed into the housing to provide greater accessibility to mount the light module and/or trim to the housing. A partition plate may be installed to push back wires/cables disposed in the housing such that the cavity of the housing is divided into a wiring compartment containing the wires/cables and a lighting compartment containing the light module and the trim. A hanger bar assembly may also be coupled to the housing to couple the recessed lighting system to a building structure (e.g., a T-bar, a joist, a stud).

摘要： A lighting module includes a heat sink having a sidewall and a partition that define a first cavity and a second cavity. A driver enclosure is disposed in the first cavity to electrically insulate a driver from the heat sink. The driver enclosure substantially fills and covers the first cavity. A light source that emits light is disposed in the second cavity together with an optical element that redirects the light. A retaining ring/optic cover covers and encloses the second cavity. The lighting module is shaped and/or dimensioned to fit into a space having a width less than 2.4 inches, a height less than 2.25 inches, and/or a volume as small as 18 cubic inches. The heat sink may also include a receptacle to couple a trim to thermally and electrically couple the trim to the heat sink to dissipate heat and to ground the trim.
