Q&A: Different methods of cleaning 3-D glasses

Cleaning 3-D glasses

What happens to 3-D glasses used to watch movies or special shows at theme parks?

This question was recently addressed by the news Web site Nina Shen Rastogi wrote:

"They usually get washed or re­cycled. There are a number of manu­facturers battling for control of the 3-D market. Most of these compa­nies make reusable glasses, though the market leader, RealD, primarily makes single-use spectacles.

Reusable glass­es are generally collected in trays and then cleaned in a dishwasher-­like machine. IMAX Corp. has its own proprietary washers that exhibitors are required to use on-site. Dolby Laboratories de­mands that theaters use a commer­cial- grade dishwasher. . . . XpanD Cinema says that some of its exhibitors have a staff member hand-clean each pair with a cloth and some light soap, whereas others choose not to clean the glasses at all — instead, they hand out individual disinfecting wipes to each custom­er. RealD established a recycling program for its dispos­able glasses in November 2008 and has collec­tion containers in each theater with a RealD screen. When containers are full, they're sent to a recycling center, where the glasses are cleaned using heat and other cleaning agents, checked manually and by machine for quality assurance, and then individu­ally repackaged."

Supreme Court removal

Is it possible for a justice sitting on the U.S. Supreme Court to be removed from office? If so, what is the procedure?

While an appointment to the Supreme Court is generally regarded as a lifetime job, justices can be removed by the same impeachment process that former President Bill Clinton went through in 1998-99.

Grounds for impeachment, according to the Constitution, are "Conviction of, Treason, Bribery, or other High Crimes and Misdemeanors."

A member of the House of Representatives must ask for impeachment of a justice (or other high-ranking U.S. officials). If a resolution to investigate is passed, the Judiciary Committee investigates and a majority vote for impeachment in the committee places the articles of impeachment before the full House. The House debates the matter, and if a majority votes for impeachment it moves to the Senate for trial. Conviction (and automatic removal from office) requires a two-thirds yes vote by senators.

Only one Supreme Court justice has ever gone through the process. In 1804, Associate Justice Samuel Chase was impeached by the House for allegedly letting his partisan opinions affect his court decisions. He was acquitted by the Senate and served on the court until he died in 1811.

Another Supreme Court associate justice, Abe Fortas, resigned in 1969 under threat of impeachment when it was reported that he was on retainer to a financier who was under investigation for securities violations.
