Abstract: This application relates to apparatus and methods for determining, assigning, and displaying order deliveries. In some examples, a computing device may obtain order data identifying at least one order for delivery during a timeslot. The computing device may transmit, to a driver's computing device, a request for deliveries for a first price during the timeslot. The computing device may receive, from the driver's computing device, a response accepting the request. The computing device may then assign the driver to the order, and determine a delivery status based on the assignment of the first driver to the first order. The delivery status may identify, for example, that the order has been assigned to the driver, an estimated delivery time, the number of items being delivered, the weight of the items, and a route taken by the driver. The computing device may also display the delivery status.

Abstract: The invention relates to the field of shipbuilding and more specifically to the screw propeller for a pod drive of a vessel, particularly an ice-going vessel, providing movement both ahead and astern in icy conditions where the ice is traversable, while also providing steering for the vessel, and to a pod drive comprising said screw propeller. To reduce the weight, and consequently the cost, of the pod drive, the screw propeller comprises a propeller hub, made so that it can be rigidly attached to the conical tailpiece of the propeller shaft, and screw propeller blades, each comprising a blade foil and a blade flange made in one piece, mounted on the propeller hub. The blade foil passes into the blade flange via a fillet joint forming the weakest portion for the possible destruction of the blade in the cross section of its foil, located immediately adjacent to the fillet joint.

Abstract: A borehole instrument includes a housing sized and shaped to fit inside a borehole, at least one image sensor disposed within the housing and configured to capture images of an inside wall of the borehole, at least one illumination light source disposed within the housing and configured to illuminate the inside wall of the borehole, a laser light source disposed within the housing and configured to emit laser light towards the inside wall of the borehole, a data processing subsystem coupled to the image sensor and configured to receive image data from the image sensor, the image data representative of images of the inside wall of the borehole. The data processing subsystem is further configured to capture borehole profile data from images containing laser light reflected from the inside wall of the borehole.
