Abstract: A bicycle includes a frame, a front fork, a fixed stop member fixed in relation to the frame, a bearing member that supports the front fork relative to the frame for rotation about a steering axis, and a compression ring. The compression ring includes a body portion between the bearing member and the front fork and a stop portion rotationally aligned with the fixed stop member to inhibit over-rotation of the front fork relative to the frame. The stop portion comprises a second material that is harder than the first material of the body portion. For example, the stop portion can include a contact surface that contacts the fixed stop member when the front fork is sufficiently rotated, and the contact surface can comprise the second material. In one embodiment, the second material comprises one or more of aluminum, titanium, ceramic, and steel. The body portion can be formed as an overmold on the stop portion.

Abstract: An overspeed safety braking mechanism for lift cars and elevator systems is described herein. The safety mechanism may comprise a safety kit secured to an overhead portion of a lift car, and configured to engage a cable to prevent a downward movement of the lift car. Engagement of the cable may occur when a threshold speed is reached. The overhead portion of the lift car is detachable upon a predetermined upward force resulting from an engagement of the safety cable from the safety kit. A primary brake system may be positioned beneath the safety kit, on or near a lift platform, configured to engage the safety cable in response to an activation of the safety kit and a detection of the threshold speed.

Abstract: A method performed by a concierge service implemented by at least one server computing device. The method includes receiving an indication from a user. The indication indicates that the user would like to purchase one or more movie tickets for a particular showtime of a movie or that the user would like to reserve one or more movie tickets for a movie that has not yet been released and for which tickets are not yet available for purchase. If the former, the concierge service completes the purchase of the movie ticket(s) for the particular showtime. If the later, the concierge service creates a ticket reservation by freezing user funds corresponding to a price of the movie ticket(s) when the movie has not yet been released, purchases the movie ticket(s) for the user after the tickets are made available for purchase, and collects the funds that were frozen.
