Abstract: An ophthalmic marking device is provided herein for marking a patient's eye. The device may include a handle and a tip with a tip element, a first portion of the tip element protruding from the tip to be exposed. The tip element is electrically conductive to resistively generate heat with electrical flow therethrough. A source of electrical power is associated with the device and electrically coupled to the tip element. The source of the electrical power and the tip element are configured to cause the first portion of the tip element to have a temperature in a range of 250° F.-450° F. Advantageously, the subject invention provides for a relatively low-cost device for marking a patient's eye and allows for creating a less traumatic marking on a patient's eye as compared to higher temperature electrocautery devices.

Abstract: A scroll compressor 10 may include an orbiting scroll having an orbiting scroll wall extending axially from an orbiting scroll plate towards a fixed scroll; a fixed scroll having a fixed scroll wall extending axially from a fixed scroll plate towards the orbiting scroll; and an axially extending drive shaft having an eccentric shaft portion so that rotation of the eccentric shaft portion imparts an orbiting motion to the orbiting scroll relative to the fixed scroll. An axial end portion of the orbiting scroll wall has a first seal for sealing between the orbiting scroll wall and the fixed scroll plate, and an axial end portion of the fixed scroll wall has a second seal for sealing between the fixed scroll wall and the orbiting scroll plate; and the first seal or the second seal has an aspect ratio of axial length to radial width which is 1.25:1 or greater.

Abstract: An enumeration prevention technique involves receiving an authentication session request which includes a validation result indicating whether a user identifier supplied by the user identifies a valid user entry in a user database. The technique further involves providing a genuine authentication session response when the validation result indicates that the user identifier does identify a valid user entry in the user database. The genuine authentication session response includes a user-expected set of artifacts to confirm authenticity of the authentication server to the user. The technique further involves providing a faux authentication session response when the validation result indicates that the user identifier does not identify a valid user entry in the user database. The faux authentication session response includes a machine-selected set of artifacts enabling the faux authentication session response to resemble a genuine authentication session response.

Abstract: An airbag module includes a retainer, diffuser, inflatable airbag, and an inflator to inflate the airbag. The diffuser is configured to disperse inflation gas from the inflator into the inflatable airbag. The retainer and/or diffuser comprise a glass-filled polymer material. The retainer includes a projection extending from a base wall. The projection couples to a hole in the diffuser flange and prevents the diffuser from rotating relative to the retainer. The inflator is coupled to the retainer by trapping an inflator flange under an overhang in a retainer cavity.

Abstract: In the disclosed example, an Intelligence Management System (IMS) collects data pertaining to operations of resources of various document processing environments operated by different entities into a database. The IMS processes data from the database according to criteria, to generate at least one anonymous performance metric representing operational performance of resources within a number of the document processing environments. The anonymous metric may be presented to a user, such as personnel of one of the operating entities. If the user has sufficient access privileges, the IMS may also generate a similar client specific metric from data for one or more environments with which the user is associated, for example, to allow benchmark comparison of the operational performance of the associated environment(s) against the anonymous performance metric.

Abstract: A method of managing resources of a histological tissue processor, the tissue processor comprising at least one retort (12, 14) selectively connected for fluid communication to at least one of a plurality of reagent resources (26) by a valve mechanism (40), the method comprising the step of: nominating resources according to one of: group, where a group nomination corresponds to a resource's function; type, where a type nomination corresponds to one or more attributes of a resource within a group; station, where a station nomination corresponds to a point of supply of a resource.

Abstract: A novel method of combustion air control for multiple burner furnaces, whereas a pressure transducer is located in the air piping downstream of each zone air flow control device. The pressure transducer sends a feedback signal to a pressure control loop that is in a logical cascade from the furnace temperature control loop. The pressure control loop repositions the air flow control device to compensate for changes in both downstream and upstream conditions. Output from the temperature control loop is interpreted by the pressure control loop as a changing remote set-point value. In one embodiment, the system is ideally suited to compensate for the pressure drop changes that occur across a zone air flow control valve, when flow rate changes occur as burners are started or stopped, thus providing a substantially higher turndown ratio and better control at low fire settings.

Abstract: An apparatus for marking metal in which a main carriage having a spray gun assembly with a stencil assembly mounted on it is moved toward and away from a piece of metal to be marked. Either the spray gun assembly or the stencil assembly is movable relative to the other in a direction transverse to the direction of movement of the main carriage. The stencil assembly has a plurality of stencil rings each having a plurality of cutouts with each ring being indexable so as to bring a specific cutout next to the piece of metal to be marked. After the indexing operation, the spray gun assembly is activated to spray molten metal through a cut-out in each stencil ring for forming the indicia.

Abstract: A geothermal well power-generation system is monitored by sensors permanently associated with the operating power generation system. These sensors detect changes in well water temperature, water pressure below and above the pump, and pump rotating speed. The data obtained is transmitted to a receiver at the earth's surface via sections of the system's plumbing which are utilized as an electromagnetic transmission line.
