Abstract: A polymer masonry unit (PMU) and methods and systems for forming PMUs are presented. In embodiments, a PMU may be made from a PMU mixture of a polymer, a quarry byproduct, such as a limestone aggregate, and water. The PMU may be ambient-dried to become a brick unit. The proportions of the PMU mixture may include 1-10% polymer, 80-90% quarry byproduct, and 1-10% water. The process for making a brick using the PMU of embodiments may avoid a kiln-firing process, which is costly, creates waste, and consumes significant energy. Furthermore, the PMU mixture may be formulated to enable the PMU mixture to be extruded from an extruder, enabling a system for making bricks to take advantage of the extrusion method, which can be very efficient and cost-effective for making bricks, and which is currently not possible with existing techniques and systems.

Abstract: A drive train for a wind-up injection device is described. The drive train includes a torsional energy storage adapted to be loaded or unloaded by a rotatable element, a rotatable user handle, a rotationally driveable expelling mechanism adapted to expel the liquid drug, and a clutch element coupled with the torsional energy storage via the rotatable element and including a ratchet for maintaining the rotatable element at one of a number of discrete angular positions against the torque of the torsional energy storage. The clutch element is adapted to transmit the torque from the user handle to the torsional energy storage, or alternatively from the torsional energy storage to the expelling mechanism. The ratchet is switchable from one position to an adjacent position by a torque transmitted from the user handle to the torsional energy storage. The drive train is adapted to dampen torque peaks visco-elastically and/or visco-frictionally.

Abstract: A method and system for aligning a component within a turbine casing, and a related turbine casing, are disclosed. In a top-on position, a location of a reference point and another, vertically spaced reference point on the lower casing are measured. After removing at least the upper casing, the reference points' locations are measured again, and the locations of a reference point on an upper surface of the HJ flange are measured. A prediction offset value is calculated for the component support position in the top-on position based on the locations. The prediction offset value may include a vertical adjustment based, in part, on a translation of a triangular spatial relationship of a number of the reference points and/or a tilt angle, a horizontal adjustment, and a HJ flange surface distortion adjustment. The component support position is adjusted by the prediction offset value to improve alignment.

Abstract: A reversible resistance exercise machine for reversing the direction of applied resistance against a movable platform of an exercising machine. The exercise machine has a frame, a carriage movably positioned upon the frame, and a plurality of biasing members. A plurality of first tension connectors are accessible near the first end of the carriage and are adapted for removably attaching selected biasing members near the first end of the carriage to resist motion of the carriage in the first direction. A plurality of second tension connectors are accessible near the second end of the carriage and are adapted for removably attaching selected biasing members near the second end of the carriage to resist motion of the carriage in the second direction. A user selectable amount of force may be applied to the carriage to resist movement in either of the first direction and the second direction.

Abstract: An exercise machine with resistance selector system for selecting the number of bias members applying a resistance force against a movable platform. The exercise machine with resistance selector system generally includes one or more switches which are connected to the movable platform. Each of the one or more switches is adapted to engage or disengage a corresponding latch. When engaged, the latch will connect a corresponding bias member to the movable platform. When disengaged, the latch will disconnect a corresponding bias member from the movable platform. In this manner, an exerciser may easily adjust the number of bias members connected to the movable platform so as to adjust the resistance force applied against movement of the movable platform along a rail.

Abstract: Systems and methods for automatic processing of receipts to capture data from the receipts are presented. Upon receiving an image of a receipt, an optical character recognition (OCR) of the receipt content embodied in the image is executed. The OCR of the receipt content results in machine-encoded text content of the receipt content embodied in the image. Tokens are generated from the machine-encoded text content and data groups are constructed according to horizontal lines of generated tokens. Potential product items are identified for at least some of the constructed data groups and the potential product items are evaluated for the at least some constructed data groups. The evaluation of the potential product items for the at least some constructed data groups identifies receipt data, such as product items and vendor information, associated with the least some constructed data groups. The identified receipt data is captured and stored with the image of the receipt in a data store.

Abstract: Systems, methods and computer-readable media are disclosed for capturing purchase information regarding purchased items of a consumer. Upon receiving an image of a receipt (a receipt image) regarding a list of purchased items, receipt text is generated. The receipt text is processed to identify the purchased items in the receipt image. Accordingly, an iteration is begun to iterate through the item blocks of the receipt text. An item block corresponds to a discrete item in the receipt text. The processing comprises extracting textual elements from the item block and matching the textual elements to a known product. Upon matching the textual elements to a known product, the consumer inventory associated with the consumer is updated with regard to the purchase of the known product.
