摘要:
A system for calibrating a rotary table (10) includes an indexing table (20) (which is a Hirth coupling table) and an angular interferometer (100), together with a control (200). The indexing table is mechanically coupled to the rotary table (this being the only connection between the rotary table to be calibrated and the calibration system), and the interferometer is set up to measure rotation of the indexing table. During rotation of the rotary table (10) to a target angle, the control (200) monitors the interferometer reading, and when this reading exceeds a predetermined threshold, actuates a drive motor (240) of the table (20) to counter rotate the table, thereby to maintain the optics (106) of the interferometer in alignment with the laser beams (L2, L3) and thus enable continuous measurement of the position of the indexing table.

A method of protecting a system from attack that includes monitoring processes running on a system, identifying behavior of the processes and attributes of the processes, grouping the processes into process sets based on commonality of attributes, and generating behavior control descriptions for each process set.

Sperm cells are stained according to processes that involve the combining of sperm cells with a fluorescent DNA selective dye at an elevated temperature in excess of about 40° C. The methods allow for a decreased staining time. The cells may thereafter be efficiently sorted according to common separation methods, including flow cytometry.

A method of and apparatus for dynamically calibrating a machine are disclosed in which a laser interferometer is provided in addition to the machine scales for taking independent measurements of a movement of a machine part while the part is in motion. As the moving machine part reaches pre-determined distances along its movement (e.g. every inch) the readings of the interferometer and the machine scales relating to the movement of the machine part are recorded and compared. Any difference is recorded for use in mapping the machine errors. In the preferred form of the invention a reflector is mounted on the machine spindle adjacent to, or in place of, a tool or measuring probe, and its movements are measured by the interferometer. The interferometer is arranged to generate a signal as each predetermined distance is reached and an infra-red signal is transmitted from the interferometer to a receiver on the machine spindle which is wired into the probe or tool detection circuits. This signal initiates reading of the machine scales in the same manner as the probe would normally operate. In this way not only can physical errors in the machine movement be corrected but time delays in the electrical signalling system can be allowed for.

Methods, systems, and computer-readable media provide for generating XML files from mainframe data. According to embodiments, a method for generating Extensible Markup Language (XML) files from mainframe data is provided. According to the method, at least one mainframe data file is received. Data is extracted from the at least one mainframe data file according to at least one selection criteria. At least one XML tag is appended to the extracted data to generate at least one XML file.
摘要:
Processes for selectively enriching a population of viable sperm cells with respect to a characteristic without physically sorting the cells are disclosed. The cells contained in such an enriched population benefit from the advantage of not being subjected to a sorting process. Processes of inseminating a female mammal and processes of forming a sperm dispersion utilizing the processes of selectively enriching a population of viable sperm cells are also disclosed.
摘要:
Processes of storing sorted and unsorted spermatozoa, in the form of a sperm dispersion, having reduced motility relative to endogenous ejaculated sperm are disclosed. The immotile spermatozoa of the dispersion tend to have a greater capacity for enduring the rigors associated with storage, transportation, and fertilization procedures. Processes for providing such sperm dispersions, for inseminating a female mammal with such sperm dispersions, as well as compositions and combinations comprising the sperm dispersions, are also disclosed.

A system, method and computer program product for providing authentication to a firewall using a lightweight directory access protocol (LDAP) directory server is disclosed. The firewall can be configured through a graphical user interface to implement an authentication scheme. The authentication scheme is based upon a determination of whether at least part of one or more LDAP entries satisfy an authorization filter.
摘要:
A herbicidal composition comprises in aqueous solution a mixture of salts of glyphosate at a total glyphosate a.e. concentration not less than about 360 g/l, wherein (a) said glyphosate is in anionic form accompanied by low molecular weight non-amphiphilic cations in a total molar amount of about 100% to about 120% of the molar amount of said glyphosate; (b) said cations comprise potassium and propylammonium (e.g., isopropylammonium) cations in a mole ratio of about 70:30 to about 90:10; and (c) said potassium and propylammonium cations together constitute about 90 to 100 molar percent of all of said low molecular weight non-amphiphilic cations in the composition.
