The electronic control device may be configured to initiate a machine-stopping sequence based at least in part on signals received from the distance measuring sensors.

Abstract: The clocks of one or more edgeQAM devices are synchronized with a master clock at the remotely located CMTS. A master clock signal may be transmitted via a dedicated gigabit Ethernet link. Alternatively, master clock information contained in a time synchronization message may be transmitted for use in adjusting local oscillators that drive local clocks at respective edgeQAM devices.

Abstract: A method for one of approving and denying a credit offering to a borrower. The method includes calculating a probability of default rating of the borrower and calculating a loss given default rating for the borrower. The method also includes integrating the probability of default rating and the loss given default rating with other information relating to the credit offering to produce a credit memorandum and automatically outputting the credit memorandum to a user so that the user can recommend one of approval and denial of the credit offering.

Abstract: A drill bit includes a bit head and a rotating bit cone. A sealing system for the drill bit includes a seal gland and a seal retained within the seal gland. The seal gland is defined by a radial cone surface, a head sealing surface and an opposed cone sealing surface. At least one of the head sealing surface and opposed cone sealing surface is not cylindrical (i.e., the surface is conical and not parallel to an axis of rotation for the cone). Additionally, the radial cone surface may be conical (i.e., the surface does not extend perpendicular to the axis of rotation of the cone). The seal is radially compressed between the head sealing surface and the opposed cone sealing surface. The use of one or more conical surfaces in the gland is provided to bias the compressed seal into a preferred dynamic sealing zone.

The separator includes a first platen mounted for vertical reciprocating movement generally on a first side of the separation path and a second platen mounted for vertical reciprocating movement generally on a second side of the separation path, each platen having a plurality of moveable guided rails. The second platen is also mounted for movement away from the first platen. The moveable guided rails on each of the first and second platens are each independently moveable in the upstream or downstream direction of travel of the log.

Abstract: A system and method for preserving and retrieving editing history of a digital image. One method includes identifying a user of an in-browser photo-editing application, retrieving a plurality of digital photographs from a data store, the plurality of digital photographs associated with at least one previous photo-editing session of the identified user, and presenting selectable images of the retrieved digital photographs on a display, each image having an associated editing history. Such a system and method provides several advantages over the prior art. First, as a user may manipulate images over the course of time in various manners with various editing programs, the entire history of such edits may be preserved. Having the editing history known and retrievable allows the user to undo any or all editing manipulations to return to an original digital image as it was originally stored in the system.

Abstract: Aspects of the subject matter described herein relate to directing fluid. In aspect, a fluid is drawn into an inlet and drawn down in an intake passage. The fluid passes into a gas-lift passage in which it travels upwards. The fluid then exits through an outlet which may be at a different elevation and/or orientation with respect to the inlet. This flow pattern is caused and maintained at least in part by pressurized gas emitted into the gas-lift passage.

Abstract: The present invention relates generally to the field of straps and tension devices and specifically relates to a device and method useful for stretching and exercise. In particular, the invention relates to an exercise device. According to one embodiment, the exercise device includes an elongated body having a plurality of columnar ladder apertures and a pad protrusion extending into at least one of the ladder apertures.

Abstract: A device receives packets associated with a program stream at an addressable communications port, and assigns them to one of a plurality of QAM channels. Multiplexed program packets, DOCSIS data or multimedia packets or a combination of both, are transmitted over the QAM channel. DSG messaging transports requests for content to a server, transports queries to mapping tables and returns information from the tables to a manager that, along with processors, determine which channel to use for downstream transport of the multiplexed streams. The manager assigns a connection identifier corresponding to a channel and program number combination to the packets, and sends the identifier, via DSG, to the requesting/receiving user device; the identifier instructs the user device how to tune and receive the requested packets. The identifier may use seven bits for program numbers, two for output port number and two for channel frequency.

Abstract: Water transfer means (86) transfers fuel cell product water from a cathode water transport plate (34) to an anode water transport plate (23) of the same or a different fuel cell, wholly within a fuel cell stack (50), (disposed within each fuel cell of a fuel cell stack (50)). The water transfer means may be a very high permeability proton exchange membrane (21a), a water transfer band (90) such as silicon carbide particles, a porous water transfer zone (107), with or without a flow restrictor (109), internal water manifolds (112, 113) which extend through an entire fuel cell stack, or internal manifolds (112a, 112b, 112c, 112d, 113a, 113b, 113c, 113d) which extend only through groups of cells between solid plates (71).

Abstract: An apparatus having various conduits moves liquid by passing gas up through it. A collector conduit transports the liquid to the bottom of the unit. A gas-lift conduit mixes the liquid and gas at the bottom and transports the mixture upwards, owing to the rising action of the bubbles and the resulting decreased density of the gas/liquid mixture. At the top of the gas-lift conduit, some of the gas may escape from the liquid and out of the apparatus. The lifted liquid may exit the apparatus at an elevation higher than the entry point of the liquid or may be directed down through a down and out conduit. A one way valve or equivalent configuration may be used to limit flow to one direction.

Abstract: A gas/liquid pump moves liquid by passing gas up through it. Pumping is accomplished by the liquid's moving through three conduits. The first, a collector conduit, transports the liquid to the bottom of the unit. The second, a gas-lift conduit, mixes the liquid and gas at the bottom and transports the mixture upwards, owing to the rising action of the bubbles and the resulting decreased density of the gas/liquid mixture. At the top of the gas-lift conduit, some of the gas escapes from the liquid and out of the unit. The lifted liquid then returns to near its original density and exits the unit through the down and out conduit.

Abstract: A system is provided having a transmitting transducer for transmitting a burst of energy in response to an electrical drive waveform. The system includes a receiving transducer for generating an electrical signal in response to arrival of the transmitted burst of energy.

Abstract: Crystal growth can be initiated and controlled by dynamically controlled vapor diffusion or temperature change. In one aspect, the present invention uses a precisely controlled vapor diffusion approach to monitor and control protein crystal growth. The system utilizes a humidity sensor and various interfaces under computer control to effect virtually any evaporation rate from a number of different growth solutions simultaneously by means of an evaporative gas flow. A static laser light scattering sensor can be used to detect aggregation events and trigger a change in the evaporation rate for a growth solution. A control/follower configuration can be used to actively monitor one chamber and accurately control replicate chambers relative to the control chamber. In a second aspect, the invention exploits the varying solubility of proteins versus temperature to control the growth of protein crystals.
