摘要： A product comprising a lower alkyl ester of a lower aliphatic carboxylic acid is produced by a process comprising reacting a lower alkyl ether with carbon monoxide in the presence of a catalyst comprising mordenite and/or ferrierite, optionally including an additional framework metal such as gallium, boron and/or iron, under substantially anhydrous conditions. More specifically, methyl acetate is selectively produced by reaction of dimethyl ether with carbon monoxide in the presence of a catalyst comprising mordenite or ferrierite, under substantially anhydrous conditions.

摘要： The occurrence of false positives and the post-processing of digital streams subjected to examination by a deterministic finite state machine for character strings are reduced by combining location-based pattern matching, e.g. on packet headers, and content-based pattern matching, e.g. on payloads of packets. One scheme allows automatic transition from a header match state into an initial state of a content matching machine. Another scheme is based on a rules graph defining strings of match states and the examination of a list of match states (rather than characters) which have been previously determined, for example by means of header matching and content matching. The latter is also capable of comparing offset and depth values associated with the match states with offset and depth criteria.

摘要： An inflatable carrying case for sensitive electronic device and other delicate devices are described herewith. The inflatable carrying case is made by stitching an outer sleeve to an inner sleeve with a layer of open cell foam glued in between. Two rigid top and bottom surfaces or plates (as 2 examples) are attached to the outer sleeve. An inflating mechanism comprising of an air valve assembly is positioned where the latch hooks over it to secure the carrying case. The inflating mechanism is used to inflate the carrying case and thus increase fortification against movement, sudden jolts and direct impact to the enclosed sensitive electronic device. The inflating mechanism is easily accessible and simply operated. Detachable pockets to carry accessories and shoulder strap are included in this invention. Many embodiments, examples, and variations are given.

摘要： A permanently-affixed lens cap is presented here. This is a lens cap which one does not have to separate from the camera, to use the camera. Unlike the existing lens caps which clip on the front, and are then removed, these caps remain on the front of the lens practically at all the times. Thus, they do not get lost, and the camera/lens is much safer because of it. Some of the features are: Crystal Clear: a Lens cover which looks like a filter, in that it screws into the filter thread at the end of the lens. This protects the expensive lens from impact and scratches. As an option, the user never has to remove it. Nano-Technology coating: Two separate layers of fine silica particles prevent scratches, and fluorine-containing resins in each layer repel ink marks. This has been used for DVD protection in the industry. Bullet-Proof: Layers of glass and (clear) plastic sandwiched to give great optical clarity, but an incredibly impact resistant front. Non-clear lens, which is permanently attached. The lens cap has a mechanism to flip out of the way. Press a button and the lens cap expands to become a shade, and exposes the front of the lens. Many other variations and extensions are also discussed in the specification and figures.

摘要： The present invention provides systems and methods for delivering a controlled amount of scent to a target user. Such methods and systems will preferably provide carefully direct boluses or streams of scent(s) to a single or small group of individual(s) using a bolus generator so as to avoid cross-contamination of scents with other persons and other locations. The present invention preferably delivers the bolus of scent as an air ring. The scented air ring moves through the air between the scent generating device directly to the user as a cohesive unit of air. This phenomenon is similar to a “smoke ring” exhaled by a smoker. The scent ring can be directed with accuracy to a localized target as small as the nose of a single user, such that the entire dosage can be delivered to only the user's direct vicinity. Such targeted delivery minimizes the amount of scent that must be delivered to achieve a desired level of scenting at the target location. Advantageously, the amount of scent that must be removed or dissipated from the user's area is also reduced. In another aspect, the present invention provides anti contamination devices that inhibit the contamination of the sequential delivery of scent chemicals.

摘要： A network in which a data packet is altered, for instance by the insertion or removal of a data portion such as a VLAN tag. The data of the data packet is read out of memory to an output means which forms the altered data packet with a new FCS portion and to a checking means which checks the integrity of the input packet using the existing FCS. The possibility for discrepancies to occur between the data supplied to the output and checking means is reduced.
