In a typical peer-to-peer network, any user of the peer-to-peer network may request a lookup of a key and its associated value. To limit access to a stored key-value pair, a storage node may verify that the lookup message requesting the key-value pair is authorized to access the payload. For example, the storage node may verify that the lookup message provides a retrieval identifier included in an access list included in the value of the stored key-value pair. The lookup message may include an origination identifier which may verify the source of the lookup message. If the lookup message is verified, the storage node may send the payload to the node sending the lookup message. If the payload is encrypted, the storage node may also send a group key suitable for decrypting the payload. The group key may be decrypted using a key known by the user associated with the provided retrieval identifier.

A quiet, non-binding articulatable spring mechanism for resiliently supporting a mattress includes a system of articulatable, sinuous springs, each having hooked ends for silencing the mechanism during use or collapse, as well as central offset portions for enabling the sinuous springs to compress to a greater extent than heretofore. Both rigid and yieldable support structures connect the spring mechanism to an item of furniture.

To provide a personalized voice email service, data pertaining to one or more of a user's email accounts, e.g., email addresses and account access data, is maintained in a folder by an information assistance service, which is unaffiliated with the email service providers (e.g., AOL, Hotmail, etc.) maintaining the user's email accounts. When the user calls the information assistance service, the user's folder is retrieved. The user's email accounts may be accessed on behalf of the user based on the email addresses and account access data in the user's folder. An information assistance provider including, e.g., an operator and/or a voice server, may present information concerning the email messages received in the user's email accounts in different manners. For example, the information assistance provider may report to the user selected email messages that satisfy one or more predetermined criteria, e.g., only those email messages which have been received since the last time the user called the information assistance service. Header information (e.g., sender/address, subject, etc.) concerning the selected email messages may be announced to the user. At the user's request, the information assistance provider may open and read a email message to the user. The user may then send a reply email message, or forward the email message to other recipients.

A printing system that dynamically adjusts the resolution at which printing will occur based on the lightness or darkness of the medium upon which the image will be printed is provided. The reflectivity of the medium upon which an image is to be printed is determined, and hence the relative lightness or darkness of the medium. The resolution at which the image will be printed is adjusted based on the determined reflectivity of the medium. For lighter colored mediums, sufficient contrast between the printed image and the medium upon which the image is printed can be maintained utilizing a lower resolution, while a higher resolution must be utilized to maintain sufficient contrast for darker colored mediums. Since it is not necessary to utilize the higher resolution for all mediums to ensure sufficient contrast is always provided, the amount of ink used by the printing system is reduced.

Catalyst compositions for use in forming polyurethane products include a gelling catalyst, a trimerization catalyst, and a cure accelerator. The gelling catalyst is a tertiary amine, mono(tertiary amino) urea, bis(tertiary amino) urea, or a combination of any of these. Any known trimerization catalyst may be used. The cure accelerator may be a diol having at least one primary hydroxyl group, and having from five to 17 chain backbone atoms chosen from carbon, oxygen, or both between the hydroxyl groups, provided that at least five of the backbone atoms are carbon. Alternatively or in addition, the cure accelerator may be a polyol having three or more hydroxyl groups, at least two of which are primary, and having molecular weights between 90 g/mole and 400 g/mole. Delayed initiation of the polyurethane-forming reaction and/or reduced demold time for producing the polyurethane part can be obtained by using these catalyst compositions.

A dynamic registration device for a mailing system that reduces the problems of dust generation, ink smearing, and print head contact is provided. The biasing force normally applied to the back panel of a mail piece, such that the front panel maintains contact with a registration plate, is controlled by an actuator such that the force can be removed when the printing module is not performing the actual printing process. Thus, the biasing force can be applied only when the print head is actually printing and the biasing force can be removed once printing has been completed. In other embodiments utilizing multiple printing modules, when one of the printing modules is inactivated, the biasing force can be removed, and the mail pieces pass through the inactive printing module without being registered against the top registration plate.
