Title: Thin film speaker apparatus for use in a thin film video monitor device
Inventor: MARKOW MITCHELL A
IPC: H04R17/00
Filed: 1998-02-20
Granted: 1999-08-01
Abstract: The present invention relates generally to audio systems implemented in computer systems and, more particularly, an audio sound system for use in a portable computer. More particularly still, the present invention relates to an audio system using piezo transducers to increase audio fidelity in portable laptop-type computers having a limited form factor for optimizing audio sound. Multimedia computers have now arrived in laptop computer systems. These multimedia computer systems typically have color LCD display panels, CD ROM drives, and audio speaker systems. Before the arrival of multimedia integrated systems in laptop computers, most laptop computers had merely a single audio source or audio output means that had very limited dynamic range. Further, a sound card capable of reproducing true high fidelity sound was typically lacking in most laptop computers. With the advent of multimedia systems, these improved sound card systems have been integrated into laptop computers, as well as the addition of stereo high fidelity sound. Unfortunately, laptop computers have a limited form factor, typically the size of a notebook or a single sheet of paper roughly conforming to the dimensions of 81/2 x11 inches, thus a limited surface area or space is available for adding speakers. Currently, the LCD display panels are of such size that room is still afforded on the monitor panel of the laptop to incorporate two small speakers in either comer.

Patent TW-405028-B (TW)
Title: Method and apparatus for predicting and displaying toner usage of a printer
Inventor: GARR CHARLES MICHAEL
IPC: G03G15/08
Filed: 1998-07-24
Granted: 2000-09-11
Abstract: An improved printer is provided that predicts how many pages can be printed before the toner or ink cartridge becomes empty, and also predicts how much time remains before this toner or ink cartridge becomes empty. This prediction is based upon the previous printing history of the printer while using this particular toner cartridge. After measuring the quantity of toner left in the toner cartridge, the printer of the present invention will display the approximate quantity of toner remaining in the cartridge on a screen of a host computer that is connected to the printer, either directly or through a network. The monitor screen of the host computer can also display the predicted number of pages remaining, based on the printer's previous usage history as described above. The toner measuring device provides a ""level change"" output signal when the remaining toner passes through a predetermined gradation threshold, and depending upon the size of the toner cartridge and upon the time and date at which the level change was detected, the predicted number of pages remaining and the actual amount of toner remaining are more accurately updated upon reaching one of these predetermined gradation thresholds. As each gradation level transition occurs, the printer calculates a new value for the ""pages per gradation"" variable, and also calculates the number of pages that have been printed since the latest cartridge was installed in the printer, the number of pages printed since the last level or gradation change, and the number of pages or sheets printed between the last two level changes. The printer also can approximate the amount of toner used in printing a particular page of print media to create a Toner Tally for each printed page, which can be used to judge the amount of toner used for one print job and compare that to the amount of toner used for a second print job. The Toner Tally uses a combination hardware/software counter to count the number of ""active"" pels of each page for a print job.

Title: Sulfur removal process from an acrylate stream
Inventor: WARNER R JAY
IPC: C07C69/54
Filed: 1998-10-28
Granted: 2001-06-07
Abstract: Broadly, the present invention is directed to a process for the removal of sulfur from an acrylate stream. In particular, disclosed is a process for the recovery and reuse of an acid catalyst employed primarily in the reaction to form acrylic esters. Reaction end components which include the acid catalyst employed in the reaction process, are directed to an extractor for contact with water. Upon contact with water, a phase separation occurs between the acid catalyst/water mixture and other organic matter. The organic matter is sent forward for product purification while the acid/water mixture is recycled to the reaction process. The present invention employs the use of an extractor to aid in the separation of the acid catalyst from the reaction by-products. This removal of acid results in fewer organic sulfur components to be emitted from the reaction process and hence is a more environmentally friendly process.
