Abstract: A system and method are provided for operating a pool of workers within a distributed computing system, wherein each of multiple computers host one or more workers. Each computer also hosts ledgers for one or more originators of tasks that are submitted to the pool for processing. A ledger identifies tasks from the corresponding originator that have been submitted to the pool and that have not yet been completed. When an originator submits a new task, the system (e.g., a coordinator) identifies a maximum number of concurrent tasks permitted the originator and determines, with reference to the originator's ledger, whether the task can be submitted to the pool without exceeding the limit. If so, the task is assigned to an idle worker (if any) and is added to the originator's ledger. After completion, the task is removed from the ledger. Obsolete or stale entries are periodically purged from originators' ledgers.

Abstract: A method for predicting a trajectory of a target vehicle in an environment of a vehicle. The method includes the steps of a) capturing states of the target vehicle, capturing states of further vehicle objects in the environment of the vehicle and capturing road markings by a camera-based capture device; b) preprocessing the data obtained in step a), wherein outliers are removed and missing states are calculated; c) calculating an estimated trajectory by a physical model on the basis of the data preprocessed in step b); d) calculating a driver-behavior-based trajectory on the basis of the data preprocessed in step b); and e) combining the trajectories calculated in steps c) and d) to form a predicted trajectory of the target vehicle.

Abstract: A self-propelled or foot-propelled vehicle comprising a scooter, particularly a collapsible microscooter, having a plurality of interchangeable wheels. Means for changing the wheels having a front fork and a rear fork, and front and rear axle means. A distance or height from handlebars to a footplate or deck of the scooter is less than 50 cm or 19½ inches (49.53 cm).

Abstract: A vehicle has a footboard 116 with side edge channels 130, each housing a rod or tube 112 forming illumination. The rods or tubes are connected to power means that include a battery or dynamo. Each rod or tube can include a transparent or translucent polymeric sheath for a series of LEDs. A switch provides on/off control and can provide different modes of illumination of the LEDs. The vehicle can be a foldable micro-scooter.

Abstract: An improved scooter incorporates a novel or novelty illumination or lighting effect. Scooters have undergone an upsurge in popularity in recent years, e.g. because of innovation such as folding scooters and micro-scooters. There is provided a scooter or other self or foot propelled vehicle or the like having a platform for supporting a user, the platform having an upper surface having illumination. The platform comprises a foot-plate, and is at least part transparent or translucent. The platform comprises a first portion extruded from metal and a second portion, which is at least part transparent or translucent, and preferably made from a plastics material.

Abstract: A scooter (110) includes a platform (116) that has an upperside and an underside. First and second walls (146, 148) depend from the underside of the platform (116) and away from the upperside of the platform (116) so as to define a space (142) between the walls (146, 148). The first wall (146) defines a void (140) that has a length that is substantially equal to the length of the space (142). At least one illuminatable means (112) is provided on the platform (116). A control box (144) for the illuminatable means (112) is provided between the first and second walls (146, 148) and within the space (142). The scooter (110) is a collapsible microscooter.

Abstract: A seesaw having a plurality of illumination means provided on both sides of a pivotable elongate member. The illumination means are controlled by control means dependent upon the inclination of the elongate member.

Abstract: A pogo stick or like device is provided and includes at least one illuminatable or illumination means. The pogo stick may have a frame including a tubular member. The tubular member may extend substantially longitudinally, may be located substantially co-axially with a central axis of the pogo stick, and may include a structural member. The pogo stick may have a pair of handles extending from the frame and may have platform means. The illuminatable or illumination means may include at least one vertically extending member, and beneficially a pair of illumination means, each including a vertically extending member located on either side of the tubular member.

Abstract: There is disclosed a vehicle, for example, a self-propelled and/or pedal vehicle such as a tricycle, bicycle, scooter, micro-scooter, or collapsible scooter, for example, adapted for use by children or infants. Accordingly, a self-propelled vehicle comprising illuminatable direction indicator means comprising left turn and right turn indictor means, which selectably operate by turning of a steering means or column of the self-propelled vehicle to the left or to the right, respectively, the steering means or column comprising handlebars in one embodiment. The self-propelled vehicle may comprise a tricycle.
