A sales transaction system utilizing electronically stored coupons including a portable handheld optical code reader for scanning symbols on paper coupons associated with product items to be purchased a host computer for receiving data associated with the scanned coupons from of the reader, and for redeeming the electronically stored coupons for each respective corresponding item purchased. Alternatively, also is provided a method of preparing paper coupons to facilitate a sales transaction by providing a customer identifier in a user's computer; inputting into the computer an electronic coupon template for a specific product; providing the customer identifier data into the coupon template; and printing a paper coupon including the customer identifier data for the specific product.

A sales incentive system utilizing a portable handheld optical code reader for use by a consumer for scanning bar code symbols corresponding to product items to be purchased, including a memory for storing symbol data of items scanned by the reader a computer receives the stored data associated with the scanned items from the memory of the reader, and selectively generates coupon information based upon sales offers for specific products currently available based upon an analysis of the stored data by the computer. A printer may be coupled to the computer for printing at the consumer's location a set of coupons corresponding to the coupon information transferred from the computer to the consumer's location.

Various optical components of an electro-optical system for reading coded indicia are mounted on a chassis snap-mounted in a housing. The optical components are supported by the chassis at an elevation relative to a printed circuit board snap-mounted to the chassis. The optical components are automatically adjusted in a test fixture.

A paper feed system for use in a printing apparatus that detects multi-feeds and separates all sheets while allowing a single sheet to continue into the machine includes a nip with a drive roller for feeding sheets. A reversible pressure roller downstream of the drive roller is connected to a motor, but idles in the direction of the paper feed in normal operation. When a multi-feed is detected, the motor is turned ON and the reversible pressure roll actuated by a controller. The reversible pressure roller has more friction with the sheet in its contact than the friction between sheets. This drives the sheet in contact backwards. This sheet can be diverted to a separate paper path using a gate mechanism and, if desired, fed back into the feed path.

Methods and apparatus for emergency rig monitoring are disclosed herein. The invention generally relates to methods and apparatus for monitoring an offshore rig. The rig monitoring systems and methods of use can relay information regarding the rig such as location, attitude (e.g. tilt, oscillation), and local water and weather conditions. The rig monitoring systems and methods can also facilitate emergency communication for rig personnel. Access to the information can be remotely initiated and the systems can be configured to automatically respond to such initiation. The rig monitoring systems are equipped with a self-sustainable power supply for operation under conditions where external power sources are unavailable. Such rig monitoring systems and methods are particularly useful on rigs that are located in waters subject to rapid and severe changes in local weather such as storms.

Described are a system and a method for anti-counterfeit barcode labels. The system may include an automatic identification symbol reader obtaining item data and a first spectral signature data; a spectral signature reader obtaining a second spectral signature data from a spectral signature; and a processor for decoding and validating a automatic identification symbol as a function of a comparison of the first spectral signature data and the second spectral signature data.

The invention provides a method for pleating a filtration material (1), having at least one filtration layer (2) and a stiffening layer (4), comprising preparing the filtration layer (2) as a non-woven layer of synthetic fibers, preparing the stiffening support layer (4) as a non-woven layer of synthetic fibers, with a majority of the fibers having an average denier at least two times the average denier of the synthetic fibers of the filtration layer (2) and sufficient in number and denier so that when attached to the filtration layer (2) produces a self-supporting composite (5), forming lines (7) of spaced apart perforations (6) in the support layer (4) with the lines (7) corresponding to intended folds (121) in a pleated filtration material (120), attaching the perforated support layer (4) to the filtration layer (2) to form the composite (5) thereof, and pleating the composite filtration material (5) by folding the composite filtration material (5) along the lines (7) of the perforations (6) in the support layer (4). A corresponding filtration material and framed filter are also provided.

An anti-spill device used in conjunction with a disposable cup and lid combination for preventing spillage through a sip hole in the lid is disclosed. The anti-spill device includes a cup gripping member that forms two arcuate-shaped flexible arms for securing the cup to the device. The device includes at least one retaining latch that is attached to the cup gripping member by a first retaining channel is integrated into the gripping member. The device further includes a horizontally flexing member connected to the gripping member by a second retaining channel that is integrated into the gripping member. Finally, the device includes a flexible sealing member with a lid engaging area which is biased to cover the sip hole in the disposable lid. A user desiring to drink the beverage within the cup gains access to the sip hole by engaging the device to lift and shift the lid engaging area away from the sip hole.

An improvement in filtration is seen by treating microfibers with a gaseous plasma at atmospheric conditions. The improvement results from etching the microfibers thereby increasing the surface area of the microfibers.
