Abstract: A weight training machine comprises: a motor; a line that is tensioned by the motor; a spool that takes up the line, wherein the spool includes a flange wherein the flange defines a capture region for the line; and a line guide adjacent to the spool, wherein the line guide prevents the line from persistently escaping from the capture region for the line.

Abstract: A strength training machine includes a first motor oriented at a first angle relative to a chassis. It further includes a second motor oriented at a second angle relative to the chassis. The first and second angles skew the motors with respect to each other.

Abstract: Dynamic strength loading per movement includes determining progress within a given state of an exercise. It further includes controlling, as a function of the progress within the given state of the exercise, a force generated by a motor of an exercise machine.

Abstract: A float glass furnace includes a melting furnace which heats raw materials to form a molten glass batch, a working end where the molten glass batch is cooled, at least one regenerator which introduces heated combustion air into the melting furnace through a port neck, and at least one oxygen lance in or proximate the port neck. The oxygen lance includes a lance pipe in fluid communication with the port neck, an outer shell surrounding the lance pipe, an inlet water passageway in fluid communication with a channel(s) between an exterior surface of the lance pipe and an interior surface of the outer shell, and an outlet water passageway in fluid communication with the channel(s).

Abstract: A gas turbine engine combustor liner having a plurality of holes defined therein for directing air into the combustion chamber. The plurality of holes provide a greater cooling air flow in regions intermediate each diffuser pipe than in other areas of the combustor liner.

Abstract: A gas turbine engine combustor liner having a plurality of holes defined therein for directing air into the combustion chamber. The plurality of holes provide improved cooling efficiency in regions of the combustor dome corresponding to predetermined hotspots.

Abstract: Devices and methods for performing an array assay are provided. Embodiments of the subject array assay devices include (1) a base, (2) a cover, and (3) a clamping member for holding the cover to the base, wherein when the cover is operatively held to the base about a structure that includes an array assembly spaced-apart from a backing element, the array assembly and the backing element are deflected to substantially the same curvature. Embodiments of the subject methods include contacting a sample with a backing element and placing the backing element supported sample in contact with an array assembly to form a structure that includes the backing element and array assembly. The structure is then held together using a subject array assay device and the array substrate and the backing element are deflected to substantially the same curvature.

Abstract: A reader is provided that, itself, addresses the issue of damage or degradation to arrays within the reader by virtue of air exposure. In doing so, experimental variability is reduced, and read/scan signal strength degradation is minimized for arrays/slides scanned or otherwise read toward the end of a run. The subject scanners employ a filter that reduces the amount of chemicals in the air inside the device that are harmful to the array, or the dye on the array. The implementation of adding a chemical filter to the reader device may be such that air is either drawn into or, alternatively, pushed through the filter into the same. It is possible that the entirety of the device may be provided with filtered air, or just the region holding slides to be scanned. Array readers so-constructed as well as associated methodology involving filtering incoming air while reading arrays are covered.

Abstract: Calibration devices for optical scanners and methods for their use are provided. The subject devices are characterized by having a polymeric coating with at least one fluorescent agent, where the devices have minimal local and global nonuniformities. The subject device may also include one or more photobleached regions. In using the subject devices, a surface is illuminated with at least one light source, fluorescence data is obtained from the surface and the optical system is calibrated based upon the obtained fluorescence data. The subject invention finds use in a variety of optical scanners, including biopolymeric array optical scanners. Also provided are kits for use in verifying and calibrating optical scanners.

Abstract: A disposable shield designed to sheath a patient control device prevents contaminants from contacting or entering the device. The shield has a bi-directional opening through which the hand-operated device is inserted and removed from the shield. A removable sealing device is used to preserve the integrity of the shield when the sealing device is removed. The shield can therefore be changed each time the device is handled by a different person, minimizing the chances of cross-contamination. The shield also extends the life of the device by preventing biological contaminants from contacting the device.

Abstract: A method and system for calibrating molecular arrays to a reference molecular array, and for subsequently calibrating the molecular arrays to maintain a constant signal-intensity-to-label-concentration ratio. In the first step of the two-step calibration method, a reference array coated with the fluorophore or chromophore used to label probe molecules is employed, while in the second step of the two-step method, a reference array coated with a stable dye is employed.

Abstract: The invention provides compositions for calibrating a fluorescence reader. The subject compositions generally relate to a solid support coated in a fluorescent agent, where the solid support has minimal local and global nonuniformities of fluorescence. Also provided by the invention are methods of calibrating a scanner using the subject compositions, and kits and programming for performing the subject methods.
