Abstract: A parking management system and methods of operation are disclosed. In one variation, a computer-implemented method comprises receiving positional data concerning a listing location from a listing client device; establishing a radius boundary based on the positional data; filtering one or more databases using the radius boundary to determine an amount of parking spaces listed and the amount of parking spaces reserved within a preset time period; calculating a location-specific transaction rate using the amount of parking spaces listed, the amount of parking spaces reserved, and the preset time period; determining a recommended listing price based on the location-specific transaction rate; and transmitting the recommended listing price to the listing client device.

Abstract: Parking space selection systems and methods are disclosed. One or more computing devices are configured to determine a first listing value based on one or more listing parameters associated with a first listing, which is secured by a first wireless device. A second listing value is determined based on one or more listing parameters associated with a second listing. The first and second listing value are compared and a difference between them is determined. It is determined whether the difference between the first listing value and the second listing value exceeds a predetermined threshold. In response to the determination that the difference exceeds the predetermined threshold, a user-selectable message is provided on the first wireless device. The user-selectable message includes a prompt configured to secure the second listing. In response to the prompt, the second listing is secured for the first wireless device.

Abstract: A lensmeter system may include a mobile device having a camera. The camera may capture a first image of a pattern through a lens that is separate from the camera, while the lens is in contact with a pattern. The mobile device may determine the size of the lens based on the first image and known features of the pattern. The camera may capture a second image of the pattern, while the lens is at an intermediate location between the camera and the pattern. The second image may be transformed to an ideal coordinate system, and processed determine a distortion of the pattern attributable to the lens. The mobile device may measure characteristics of the lens based on the distortion. Characteristics of the lens may include a spherical power, a cylinder power, and/or an astigmatism angle.

Abstract: Spinnable frames for spectacles are provided. A spinnable frame allows a user to hold a distal end of one of the temples and freely spin the remainder of the spectacles around that end of the temple. A spin joint is provided in at least one of the temples that allows this spinning action. The spin joint may span an interface between the distal end of the temple and a proximal end of the temple, the proximal end being coupled to a front portion of the frame at a hinge interface. In this way, the temple arm is allowed to fold against the front portion for compact storage, as with conventional eyeglass frames, while facilitating spinning of the spectacles in a way that avoids excess forces on the hinge interface and/or other portions of the frame or lenses mounted therein.

Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for virtual try-on of items such as spectacles. A virtual try-on interface may be implemented at a server or at a user device, and may use collision detection between three-dimensional models of the spectacles and of a user's face and head to determine the correct size and position of the spectacles for virtual try-on. With the determined size and position, a virtual representation of the spectacles is superimposed on an image of the user.

Abstract: A method of operating a pupillary distance system is disclosed. The method comprises the steps of capturing, with at least one camera of the pupillary distance system a 2D image and a corresponding 3D depth map of a face of a subject. A determination of pupil localization information is made using the 2D image and corresponding 3D depth map. The pupil location is further refined based on the pupil localization information. Pupil center coordinates are determined and the pupillary distance is calculated for a subject between centers of each pupil. Processes and uses thereof are also disclosed.

Abstract: Vehicular movement detection systems and methods are disclosed. One or more computing devices are configured to monitor location data associated with a first user device. It is determined that a first user device enters a geographic area based on the location data. In response to determining that first user device has entered or departed a geographic area, a message is prompted on the first user device using a first software application. The message includes executable instructions that launch a second application the first user device, and cause the first user device to transmit a search request for a listing location with one or more search request parameters automatically generated in response to the executable instructions. A confirmation identifier is received by the first user device, the confirmation identifier being useable for unlocking a secured area.
