Abstract: Systems and methods for unraveling braids of real/natural hair and/or synthetic braid extensions, or a combination thereof, work from the bottom of the braid up using one or more tines automated to repetitively penetrate the braid and pull through and down it to unravel it. The systems and methods may unravel braid/entanglements faster than could otherwise be done manually by hand.

Abstract: A robot including a main brush; a peripheral brush; a first actuator; a first sensor; processors; and memory storing instructions that when executed by the processors effectuate operations. The operations include determining a first location of the robot in a working environment; obtaining first data from the first sensor or another sensor indicative of a value of an environmental characteristic of the first location; adjusting a first operational parameter of the first actuator based on the sensed first data; and forming or updating a debris map of the working environment based on data output by the first sensor or the another sensor configured to collect data indicative of an existence of debris on a floor of the working environment over at least one cleaning session.

Abstract: A computer-implemented method that includes displaying a graphical user interface (“GUI”) and receiving personalized information from at least one server computing device. The GUI includes a page. The personalized information identifies a theatre location, movies playing at the theatre location, dates, and showtimes associated with the movies and dates. The method includes displaying on the page, the movies, dates on which a particular movie is showing, and a particular showtime on a particular date. A selection is entered by the user into a user input displayed on the page. The selection changes the theatre location, the particular movie, the particular date, and/or the particular showtime without the user exiting the page. The page updates automatically to display the user selection. An indication is received that the user has selected a purchase input display on the page, and a purchase of at least one movie ticket is completed.

Abstract: Provided is a robot, including: a main brush; a peripheral brush; a first actuator; a first sensor; one or more processors; and memory storing instructions that when executed by at least some of the one or more processors effectuate operations including: determining a first location of the robot; obtaining first data indicative of an environmental characteristic of the first location; adjusting a first operational parameter of the first actuator based on the sensed first data; and forming or updating a debris map of the working environment based on data output by the first sensor or another sensor configured to collect data indicative of an existence of debris on a floor, wherein the debris map at least indicates areas covered by the robot and with a high level of debris accumulation; and an application of a communication device paired with the robot and configured to at least display the debris map.

Abstract: A bicycle includes a chainstay protector having an upper surface including a valley, a first peak, and a second peak. The first peak extends upwardly from the valley toward the chain and has a first contact surface positioned to contact the chain a first height above the valley. The second peak extends upwardly from the valley toward the chain and has a second contact surface positioned to contact the chain a second height above the valley. The first contact surface is spaced from the second contact surface by a gap that is at least 5 times the first height. Each of the first and second contact surfaces has a length that is less than the length of the gap and less than two times a pitch of the chain.

Abstract: Systems and methods for creating a collaborative video campaign comprise establishing the campaign via a graphical user interface of a computing device by automatically authorizing one or more individuals each having image capture devices as remote contributors to contribute videos to the campaign based upon a meeting of one or more pre-determined criteria; setting up the campaign to automatically begin based upon the meeting of the one or more pre-determined criteria; creating, via the graphical user interface of the computing device, a list of shot templates for desired videos for collection through the campaign, generating a notification regarding the automatic authorization of the one or more individuals from the graphical user interface, and; sending the notification regarding the automatic authorization through a remote server to the one or more image capture devices of the one or more remote contributors.

Abstract: Embodiments disclosed herein relate to solar tracking apparatuses, systems that include the same, and methods of operating the same. An example solar tracking apparatus includes a structure attachment portion configured to be attached to a structure (e.g., a moveable or stationary structure) and to remain relatively stationary relative to the structure. The structure attachment portion may include one or more mounts configured to attach the structure attachment portion to the structure. The solar tracking apparatus also includes at least one solar panel portion coupled to the structure attachment portion. The solar panel portion may be configured to move relative to the structure attachment portion and the structure. For example, the solar tracking apparatus may include one or more actuators coupled to solar panel portion configured to move at least a portion of the solar panel portion relative to the structure attachment portion.

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.

Abstract: An overspeed brake system is described to engage a safety cable and subsequent brake system once a threshold speed is reached. An overspeed safety kit may be installed on an elevator system or lift car, to identify a threshold speed and engage a brake lever to activate a braking system. One or more brake engagement devices may be applied to limit the force on the brake lever during a fall, thereby preventing potential damage to brake components, while cushioning the deceleration.
