Abstract: In a system with an elevator system, a host can grant a visitor access to a building and switch the elevator system into a visitor operating mode in order to transport the visitor to a destination floor. The host can initiate a movement of the elevator car to a first defined floor, on which a visitor would like to enter an elevator car, by means of an input on a mobile device. A camera arranged in the elevator car and a camera recording, which is produced by means of said camera and displayed on the mobile device, enable the host to check if only the user is located in the elevator car. If this is the case, the host can initiate the movement of the elevator car to the destination floor by means of an additional input on the mobile device.

Abstract: An elevator includes a car, a counterweight, a suspension working together with the car and the counterweight, and a wheel at least partially wound around by the suspension. The suspension includes a tie beam arrangement with two tie beams and an encasing shell wherein a ratio of the width of the suspension to the height thereof is in a range between one and three. The wheel includes a flute having a flat base for guiding the suspension. When the suspension is unloaded, there is an air gap between the suspension and a guide region of the flute. The suspension is ovalized under loading to close the air gap. The shell is coated, at least in areas, on the outer surface thereof, wherein the coating optionally has a friction-reducing, friction-increasing, and/or wear-detecting effect.

Abstract: A method and apparatus for monitoring an elevator drive brake wherein the method includes the steps of detecting a spring force (Fs-closed) when the brake is closed, detecting a spring force (Fs-open) when the brake is open, determining the difference between the two detected spring forces (?Fs), and comparing the difference between the two detected spring forces with at least one preset permissible force differential (?Fsmin; ?Fsmax) to determine whether the brake is defective. The apparatus includes a force sensor for each brake spring to be monitored, and an electronic monitor that stores at least one preset permissible force differential (?Fsmin; ?Fsmax) and, during operation, compares the at least one preset permissible force differential with an actual force difference (?Fs) between an open spring force (Fs-open) and a closed spring force (Fs-closed) as detected by the force sensor.

Abstract: A testing device includes a receiving unit for electromagnetic signals arranged on a carrier element to be tested to generate test data from received electromagnetic radiation. The test data are evaluated in a processing system in order to determine a deviation of the test data from a nominal state of the carrier element. The testing device is used to test a carrier element of an elevator installation on which the elevator car is suspended.

Abstract: An elevator system includes a car or platform to transport passengers and/or goods as well as a counterweight, which are arranged as traversable or movable along a travel path, and which are coupled and/or with a drive by a suspension element interrelating their motion. The suspension element is guided and/or driven by a traction sheave and/or a drive shaft and/or a deflecting pulley. The suspension element is a sheathed and/or belt-type, with a first layer made of a first plasticizable and/or elastomeric material and a second layer with a connection plane formed between the first and second layers. At least one tension member—rope-type, tissue-type, or comprising a multitude of partial elements—is embedded in an area of the connection plane, a majority of a surface of said at least one tension member directly contacting said first layer. A manufacturing procedure for one of the suspension elements is provided.

Abstract: An elevator includes a car, a counterweight, a suspension working together with the car and the counterweight, and a wheel at least partially wound around by the suspension, wherein the suspension comprises a tie beam arrangement made of two tie beams and a shell encasing the tie beam arrangement, said shell comprising a longitudinal structure in an area of an outer surface partially winding around the wheel, and wherein the ratio of the width of the suspension to the height thereof is greater than one and less than or equal to three. The wheel comprises a groove for guiding the suspension on the sides, in which the suspension is at least partially received, and the groove floor thereof being formed flat. The shell is coated, at least in areas, on the outer surface thereof, wherein the coating optionally has a friction-reducing, friction-increasing, and/or wear-reducing effect.

Abstract: An elevator installation contains an elevator car (12) that is arranged movably between floors (S1, S2) in an elevator hoistway (11). The elevator car (12) has a car door (14), and the elevator hoistway (11) has on the each floor (S1, S2) a hoistway door (13). Assigned to the car door (14), or to the hoistway door (13), is a sill-section (16). To draw attention to a gap (30), or give a warning of a step, between elevator car (12) and floor (S1, S2), it is proposed to arrange in the sill-section (16) of the elevator car (12), or of the floor (S1, S2), at least one light module (20, 21, 22).

Abstract: An elevator the drive unit is arranged laterally in a top section of an elevator shaft and, as seen from a shaft door opening, at a side wall of the elevator shaft. At least one cable is guided over deflecting rollers of a support frame of the elevator car and over deflecting rollers of the counterweight and serves as a support and drive cable for the elevator car or the counterweight. The cable is guided over a drive pulley of the drive unit and is arranged transversely to the side wall. The support frame is constructed as a rucksack frame with an upright frame guided by guide rails and a horizontal base frame on which the elevator car is arranged. On travel to the uppermost stopping point, the upper part of the elevator car travels past the drive unit.

Abstract: The automatically operated door is controlled in dependence upon the presence and movement conditions of one or more persons present on a support surface within a predeterminate space on a predetermined side of the automatically operated door. A radiation source, particularly an infrared radiation source emits a radiation field along and at a predetermined height above the support surface so that the at least one person present on the support surface is irradiated and infrared reflections originate from the at least one irradiated person. The infrared reflection is received at an active imaging device such as, for example, an infrared camera. Such imaging device contains a liquid crystal display (LCD) unit with an associated microshutter and a linear image sensor arranged in a plane extending substantially parallel to the plane of the liquid crystal display unit.
