Abstract: For densely-populated cities in particular, finding suitable vehicle parking may often be problematic. Vehicles range widely in size and parking characteristics, drivers and passengers may have preferences and/or physical limitations for parking space features (such as needing a wide bay or to be within a certain proximity of a destination when they park due to limited mobility or due to delivery of a heavy or large item). According to aspects of the invention there is provided a computer-implemented system and method for dynamically serving parking space requests for a vehicle.

Abstract: Seat assemblies are provided. In some embodiments, a seat assembly includes a seat member having a first seat surface, a second seat surface, and a third seat surface opposite the second seat surface. The third seat surface is substantially parallel to the second seat surface and the first seat surface is substantially perpendicular to both the second seat surface and the third seat surface. The seat assembly also includes a first side panel affixed to the second seat surface and a second side panel affixed to the third seat surface. Each one of those panels is substantially perpendicular to the first seat surface. The seat assembly further includes a bin movably affixed to the first side panel and the second side panel. The bin includes an open compartment and can be moved between a closed position that obstructs the compartment and an open position that permits access to the compartment.

Abstract: An edge restraint and method of use where the edge restraint has a vertical wall for retaining segmental pavement in an installation placement and a horizontal base having a plurality of teeth extending therefrom and providing discrete focused points for providing friction between the edge restraint and an installation surface to prevent horizontal movement of the edging in at least one direction with respect to the installation surface. A leading edge of the base is installed under a first surface with the wall providing a barrier between the first surface and a second surface for engaging the teeth with a third surface to prevent movement of edging in a horizontal direction away from the first surface.

Abstract: The invention relates to optical modulation devices and, in particular, monolithically integrated optical modulation devices. Disclosed herein is a monolithically integrated optical modulation device (200) that comprises: an input optical port (210); an output optical port (215); and an optical waveguide for guiding light from the input optical port to the output optical port. A portion of the optical waveguide is split into at least two branches. The waveguide is configured to cause a net 180° change in direction of the light while guiding said light from the input optical port to the output optical port such that the input optical port and the output optical port are positioned on a first edge of the device. At least some of the net 180° change in direction is achieved within the branches of the waveguide.
