The invention is a system and method for handling items to be shipped that securely verifies the sender. The invention makes use of pre-printed, unique, labels which are affixed by hand or machine to items to be mailed or shipped. These labels are packaged and distributed in groups. The groups of labels can be sold or freely distributed. Each person or organization that originates shipments is assigned a unique customer account number and their identity is authenticated when this account is created. The group number for a group of labels is linked to a customer account prior to the use of any of the labels from the group. The linking can be done at the time of sale or distribution of the group of labels, or after the sale or distribution thereof. Post-sale linking of a group of labels to a customer account can be done over the phone or through a web-site. The invention overcomes limitations in the prior art by creating a method for authenticating the sender of each item without requiring the use of a computer, printer, postage machine, or any other specialized hardware by the sender. The unique label identifiers are stored in a database that is used to ensure that each label that can be used only once. The invention is suitable for bulk mail processing and individual mail items. The invention provides a method for making selective use of specialized handling equipment, including equipment to irradiate the mail to destroy biological agents.

A novel method is set out of preparation of radioactive diagnostic radiopharmaceutical in a stable, shippable, lyophilized form by an apparatus designed to rapidly flash freeze and dehydrate a radiopharmaceutical composition to minimize auto radiolysis. The method proposes rapid cooling and removal of ambient vapor, and then ultra cold removal when the potential of explosive liquid oxygen is eliminated. The radioactive diagnostic radiopharmaceutical requires no further cold or refrigerated storage, including with respect to shipping, subsequent to stabilization. The preferred composition can be reconstituted “on site” by the addition of a suitable diluent to bring the radiopharmaceutical complex into solution at a desired concentration.

An aqueous binder composition is provided that includes a protein-containing biomass and a pH adjuster. Optionally, a crosslinking agent and/or a moisture resistant agent may be included in the binder composition. The protein-containing biomass is natural in origin and may be derived from plant or animal sources. The pH adjuster is used to adjust the pH of the binder to a desired pH and lower the viscosity of the protein-based biomass. In addition, the pH adjuster may act as a crosslinking agent. The crosslinking agent may be any compound suitable for crosslinking the protein-containing biomass and reacting with the moisture resistant agent, when the moisture resistant agent is present in the binder. In addition, the binder has a light color after it has been cured. The environmentally friendly, formaldehyde-free binder may be used in the formation of insulation materials and non-woven chopped strand mats.

Techniques are disclosed for methods and systems for automating the operation of vehicle lifts in the servicing of automotive vehicles. The lifts may be motorized mobile column lifts and/or fixed lifts, including two-post lifts with swing-arms and a variety of drive-on lifts. Motorized mobile lifts have a motorized transport mechanism. A guidance system first assigns available motorized mobile lifts to the axled wheels of a vehicle and then directs their transport mechanism for transporting them to their engagement locations. It also guides the engagement of both the motorized mobile lifts and the fixed lifts in the service center. A number of technologies may be used for this purpose, including sensors onboard the vehicles and/or the lifts and/or the service center. A computer vision pipeline may also be utilized to assist in the process. Machine learning may also be employed. Techniques are also extended to autonomous vehicles as well as interfacing with fleet management software.

A method for providing interactive training, whereby a video display and a base station are coupled in communication with a computer. A plurality of wireless handheld remotes are configured for wirelessly communicating with the base station, and each of the remotes is operable by a respective trainee of a group of trainees. Each remote has a remote ID unique from all other remotes and is stored in non-volatile memory of the computer; and the base station includes a base station ID code unique from all other base stations, and the base station ID is stored in non-volatile memory of each remote. Each remote remains in an inactive state and is operable to be activated via a respective activate signal transmitted from the base station, and the base station is operable to transmit an activate signal to one or more of the remotes, the activate signal being effective for enabling the remote to transmit a signal, wherein the remote is deactivated upon completion of transmission of signal. Using unique IDs prevents interference from other wireless devices including remotes paired with other base stations. It also makes it unnecessary for one training system to operate on a different channel from another training system.

A control mechanism is structured to move the member of the racking mechanism between the first position and the different second position of the member responsive to a number of remote commands.

A method of reducing the emission of formaldehyde from fibrous insulation having thereon a formaldehyde-based binder is provided. In particular, an amine-based compound is added after the formaldehyde-based has been cured and prior to the insulation being processed for storage or shipment to customers. The amine-based compound may be added after binder cure and either prior to the insulation product being cut into nodules or after the insulation product has been cut into nodules. Non-limiting examples of amine-based compounds include urea, melamine and/or dicyandiamide. Once applied to the insulation product, the amine-based compound acts as a formaldehyde scavenger to reduce the emission of formaldehyde into the air. In preferred embodiments, the amine-based compound is added with an antistatic agent. The post-cure addition of urea to fibrous insulation reduces the emission of formaldehyde into the atmosphere to meet stringent GREENGUARD standards and achieve GREENGUARD certification for formaldehyde emission.
