Abstract:
A dental prophylaxis angle and handpiece assembly for cleaning and polishing teeth is provided. The dental prophylaxis angle is removably attached to the dental handpiece by an interlocking mechanism that includes extension locking tabs, a locking annular member, and an interlocking drive member in the handpiece. The prophy angle is securely snap-fitted onto the handpiece and locked in place so that it has minimal lateral movement. After the prophy angle has been used to treat a patient, it can be removed easily from the handpiece and disposed thereof.
Abstract:
An automated method causes a terrestrial solar cell array to track the sun. The solar cell system includes motors that adjust a position of the array along different respective axes with respect to the sun, wherein a first motor adjusts the inclination angle of the array relative to the surface of the earth and a second motor rotates the array about an axis substantially perpendicular to that surface. The method includes (a) using a software algorithm to predict a position of the sun at a future time; (b) using a computer model to determine respective positions for the motors corresponding to the solar cell array being substantially aligned with the sun at the future time; and (c) activating and operating the motors at respective particular speeds so that at the future time the solar cell array is substantially aligned with the sun. The future time may correspond to any time during operation. An initial future time may correspond to a start up time after sunrise at which point the solar cell is to begin tracking the sun.

Abstract:
Disclosed is an eye alignment apparatus which mounts on the bow and allows the archer to properly position the archer's eye with the bow and the aiming indicia, if any, otherwise mounted on the bow. The eye alignment apparatus includes a framework, a lens, a second alignment indicia on or near the lens, and a first alignment indicia spaced apart from the second alignment indicia. Additional features include a level indicator and an angular adjustment mounting mechanism.
Abstract:
An alignment device for aligning solar cell modules of a solar tracking photovoltaic array relative to the sun. The alignment device may be mounted on at least one planar solar cell module so that an axis of the device is substantially perpendicular to the planar surface of the module. The device may include a convex lens at one end for focusing incoming rays of the sun into a focused beam, and a planar photodetector at a second end positioned so that the focused beam aligns on a predetermined point of the photodetector when the modules are correctly aligned. The instrument may also include a plurality of leads attached to the photodetector to provide a signal indicative of an angular misalignment of the at least one module.
Abstract:
An apparatus includes a set of network communication modules, a communication control module and an input actuator. Each network communication module from the set of network communication modules is configured to send signals to and receive signals from a remote device via a distinct communication mode from a set of communication modes. The communication control module is configured to periodically send a set of second status signals intended to be sent to the remote device via each communication mode from the set of communication modes when the communication control module is in an emergency operating mode and the communication mode is available. The communication control module is configured to switch from the default operating mode to the emergency operating mode in response to receiving an input signal indicating that the input actuator has been actuated.
Abstract:
The terrestrial solar tracking photovoltaic array includes a longitudinal support that may be constructed of discrete sections. The overall length of the array may be adjusted depending upon the necessary size of the array. A drive may be configured to rotate the longitudinal support in first and second directions about a first axis. Solar cell modules are positioned along the longitudinal support and may each include a rectangular case with a plurality of lenses that are positioned over corresponding receivers. Linkages may be connected to the solar cell modules and are axially movable along the longitudinal support to rotate the solar cell modules within second planes that each orthogonal to the first plane to further track the sun during the course of the day. The array may be configured to facilitate rotation about the first axis. The array may be constructed with a center of gravity of the array to extending through the longitudinal support.

Abstract:
The invention relates to the detection and quantification of polypeptides using mass spectrometry. Specifically, the invention provides a method for testing whether a target polypeptide is present in a sample of a set of polypeptides, a method for deriving a value for distinguishing polypeptides of a set of polypeptides from each other, a database containing values for distinguishing each polypeptide of a set of polypeptides from each other, and an apparatus for configuring a mass scan of a mass spectrometer to test whether a target polypeptide of a set of polypeptides is present in a sample of the set.
Abstract:
An automated method causes a terrestrial solar cell array to track the sun. The solar cell system may include motors that adjust a position of the array along different respective axes with respect to the sun. An alignment analysis procedure, e.g., a find sun routine, is performed to ensure that the solar cell system is properly aligned with the sun during solar tracking. This procedure may sweep the solar cell system along determined paths (e.g., azimuth and elevation paths) while measuring an output parameter indicative of system performance. The measured data is analyzed to determine if the solar cell system is in misalignment in which case the solar cell system is moved into proper alignment. The alignment procedure may be implemented on a periodic basis or using triggers, and maybe automatically executed or manually executed.
