Abstract: Embodiments of the disclosure are drawn to apparatuses and methods for a rotating optical reflector. Optical systems may have a limited field of view, and so in order to expand the area that the optical system collects data from, the field of view of the optical system may be scanned across a target area. The present disclosure is directed to a rotating optical reflector, which includes a transmissive layer which refracts light onto a reflective layer, which has a normal which is not parallel to the axis about which the optical reflector is rotated. The optical reflector may be both statically and dynamically balanced, which may allow an increased size of the optical reflector, which in turn may increase the aperture of an optical system (e.g., a lidar system) using the rotating optical reflector.

Abstract: A coating having a hydrogel layer of a hydrogel of a polysaccharide and polymer brushes attached to the hydrogel layer. A process for making the coating, having the steps of: a) providing the hydrogel layer on a substrate, b) attaching an initiator having a radically transferable atom on the hydrogel layer and c) reacting monomers with the initiator to form the polymer brushes attached to the hydrogel layer.

Abstract: A method of collecting and analyzing data over a network is disclosed which for embedding in webpages and which collects feedback from a plurality of users, and processes the feedback to detect sentiment, which may be presented in a chart. Processing may comprise parsing the feedback, breaking it down into parts, labelling the parts and assigning a numerical value depending on sentiment. The chart may form part of an intuitive and simple to use dashboard display.

Abstract: A method of processing receipts, including: obtaining transaction data including a plurality of categories of information necessary to describe a purchasing transaction of a customer at a store location; obtaining image data representing a receipt corresponding to the purchasing transaction of the customer at the store location; obtaining an e-mail address of the customer; providing an option to print the receipt at the store location and an option to e-mail the receipt to the customer; obtaining a selection of at least one of the provided options; if the option to print is selected, initiating printing of the image at the store location; and if the option to e-mail is selected, sending an e-mail to the e-mail address of the customer, the e-mail including providing at least one of the image data and the transaction data.
