Abstract: A hybrid tubular pipe burner has a lateral flame emitted from a slot in the tubular pipe burner, the tubular pipe burner being supplemented with the placement of spaced electric heaters disposed outside the pipe burner. The electric heaters run along the length of the pipe burner but are disposed such that they stand off and away from the surface of the pipe burner. The pipe burner is configured to allow for initial gas firing and preheating. Upon reaching the required temperature, the gas firing will cease and the electric heaters will take over. The gas is used for preheating only. The continued flow of air through the pipe prevents deformation of the pipe in the pipe burner.

The spigots support one of the glass panels and comprise a base, a first arm, a first pad, a second arm, and a second pad. The first pad has a first pad surface and a lower surface. The first pad surface is in contact with the first arm and the glass panel. The lower surface extends from the first pad surface and is in contact with the glass panels. The second arm has bores. The second pad has a second pad surface, a backing, a plate, and fasteners. The second pad surface is in contact with the glass panel. The backing is spaced apart from the second pad surface and has backing openings aligned with the bores. The plate is located between the second pad surface and the backing. The fasteners pass through the bores and the backing openings to contact the plate.

Abstract: Herein, a “perception statistical performance model” (PSPM) for modeling a perception slice of a runtime stack for an autonomous vehicle or other robotic system may be used e.g. for safety/performance testing. A PSPM is configured to: receive a computed perception ground truth t; determine from the perception ground truth t, based on a set of learned parameters, a probabilistic perception uncertainty distribution of the form p(e|t), p(e|t,c), in which p(e|t,c) denotes the probability of the perception slice computing a particular perception output e given the computed perception ground truth t and the one or more confounders c, and the probabilistic perception uncertainty distribution is defined over a range of possible perception outputs, the parameters learned from a set of actual perception outputs generated using the perception slice to be modeled, wherein each confounder is a variable of the PSPM whose value characterized a physical condition on which p(e|t,c) depends.

The second receiving portion is adapted to pivot about a longitudinal axis of the second pivot member.

Abstract: Herein, a “perception statistical performance model” (PSPM) for modelling a perception slice of a runtime stack for an autonomous vehicle or other robotic system may be used e.g. for safety/performance testing. A PSPM is configured to receive a computed perception ground truth, and determine from the perception ground truth, based on a set of learned parameters, a probabilistic perception uncertainty distribution, the parameters learned from a set of actual perception outputs generated using the perception slice to be modelled. A simulated scenario is run based on a time series of such perception outputs (with modelled perception errors), but can also be re-run based on perception ground truths directly (without perception errors). This can, for example, be way to ascertain whether perception error was the cause of some unexpected decision within the planner, by determining whether such a decision is also taken in the simulated scenario when perception error is “switched off”.

Abstract: A computer-implemented method of modelling a common structure component, the method comprising, in a modelling computer system: receiving a plurality of captured frames, each frame comprising a set of 3D structure points, in which at least a portion of a common structure component is captured; computing a first reference position within at least one first frame of the plurality of frames; selectively extracting first 3D structure points of the first frame based on the first reference position computed for the first frame; computing a second reference position within a second frame of the plurality of frames; selectively extracting second 3D structure points of the second frame based on the second reference position computed for the second frame; and aggregating the first 3D structure points and the second 3D structure points, thereby generating an aggregate 3D model of the common structure component based on the first and second reference positions.

Abstract: A system for facilitating construction of a deck comprises a server, a client computer, and a database. A user inputs, through a graphical user interface on the display of the client computer, a configuration for the deck. The server receives the deck information from the client computer and determines, based on information in the database and the deck information, a parts list. An augmented view depicting the deck in a background view of the client computer may also be generated for viewing on the user interface.

Abstract: A safety auditor is designed to perform opening and closing of every safety switch that is used in an industrial bakery oven. Every pressure sensor can be tested for on and off states. The low gas pressure switch can be vented and the high gas pressure switch pressurized. All thermocouples associated with the high temperature circuits are tripped. Fans are started and stopped over a communications signal or via the hard-wired interface as required to generate the safety testing. Once the safety testing is complete, the results along with time, date, name of tester, pass or fail will be printed out via a small kiosk printer. This ticket can then be filed in an office. As the operation is easy to do and requires little effort, it is much more likely to be performed and therefore safer for the host bakery.

Abstract: A system for facilitating construction of a deck comprises a server, a client computer, and a database. A user inputs, through a graphical user interface on the display of the client computer, a configuration for the deck. The server receives the deck information from the client computer and determines, based on information in the database and the deck information, a parts list and instruction information. The instruction information includes information on the alterations to the parts needed to construct the deck. The parts list and the instruction information may be displayed on the user interface.
