Abstract: Some embodiments of the invention include a thruster system comprising a thruster and a pulsing power supply. The thruster may include a gas inlet port; a plasma jet outlet; and a first electrode. In some embodiments, the pulsing power supply may provide an electrical potential to the first electrode with a pulse repetition frequency greater than 10 kHz, a voltage greater than 5 kilovolts. In some embodiments, the pressure downstream from the thruster can be less than 10 Torr. In some embodiments, when a plasma is produced within the thruster by energizing a gas flowing into the thruster through the gas inlet port, the plasma is expelled from the thruster through the plasma jet outlet.

Abstract: A medical aerosol device comprising a jet nebulizer within an aerosol chamber, a heating unit, and a liquid source. The jet nebulizer comprises a jet nozzle and an orifice in fluid communication with the liquid source, and functions by passing a jet of oxygen across the face of the orifice to draw liquid from the fluid source and through the orifice, where it is finely dispersed into an aerosol by the jet stream. The orifice includes an impinged portion curved to direct additional airflow across the orifice face, which is also canted away from the jet stream, which together results in a stronger and more consistent suction force on the liquid, and an aerosol in which at least 80% of the individual droplets are five microns or less. An improved heating control system and composition of a heating platen is also contemplated, as well as a method of use.

Abstract: A computer method that is used to control call center volumes for a range of dates. The method involves utilizing previous mailing campaign and call center response data to determine when the mail arrives in the home and when a call center is contacted in response to information in the mail; predicting the call center volumes based initially on the previous campaign and call center response data and as the mailing campaign and call center responses progresses updating call center predictions based on current mailing campaign data; and determining in home mail volumes needed to control call center volumes.

Abstract: A method for obtaining mail discounts by determining a date a mail piece should be mailed and adjusting the date the mail piece is mailed to fill one or more mailing trays with mail pieces that were originally planned to be mailed on different dates to obtain postal discounts

Abstract: A coordinated direct marketing contact strategy between the direct mailing and the other marketing channels. The method determines the marketing prospect names that are common between the direct mailing and the other marketing channels being used in the direct marketing campaign. Then, using mail prediction with the common names between marketing channels the method determines the probability of the prospect receiving the mail piece on a certain date or dates. For each common name the method calculates the contact date(s) for the other contact channels based on the marketers contact strategy and the predicted in home dates. The method then aggregates the individual contact strategies into an overall contact strategy which enables other channels to coordinate with the direct mailing. This process is repeated over several campaigns to benchmark campaign performance that can then be used to analyze and refine future campaign execution.

Abstract: A method for enabling a mailer to infer the amount of business reply that he/she is going to receive on a given day and determine the amount of postage that is due. The foregoing is accomplished by placing a planet code that references the mailer's permit number on the business reply so that when a scanner at the USPS reads the planet code, the postage for the business reply will be calculated, and the mailer will be notified of the calculation so that the mailer may deposit sufficient funds in a deposit account to pay for the postage. The mailer may deposit funds in the account by issuing a check, having funds automatically transferred from some account, or automatically having a check issued so that someone may take the check to the USPS and receive the business reply. Thus, the mailer will be able to determine the amount of postage that is going to be charged to his/her account.

Abstract: A low pressure alarm assembly where a switch for activating a low pressure alarm is operably associated with a link assembly which is operably actuable in response to the movement of a pressure responsive element. In one embodiment, the link assembly incorporates a pointer which is adapted to sweep across the plate of a pressure gauge into contact with the switch to close the switch and activate the low pressure alarm.

Abstract: This invention creates a hierarchy of radio frequency identification tags that are related to the mail pieces in mail trays and the pallet on which the mail trays sit. This hierarchical method provides a layered approach that is designed to minimize the probability that a mailer or the post office will misassemble or misroute a mailing or elements of a mailing.

Abstract: A method for matching a manifest or statement of a mailing with the mail pieces contained in a tray. The method is accomplished by: printing a pattern on the edge of mail pieces; placing the mail pieces in a tray; and printing the pattern on the manifest or statement of mailing and on the edges of the mail pieces contained in the tray.

Abstract: A method for tagging the mail pieces in a mail tray and validating the integrity of the mail pieces in the tray. The method is accomplished by: determining the measurement of an edge of each mail piece that will be placed in a tray; determining the thickness of each mail piece that will be placed in the tray; determining the number of mail pieces that will be placed in the tray; calculating an incremental pattern dab that is going to be placed on the edge of each mail piece; placing a portion of the pattern on the edge of each mail piece that is going to form the mail pieces of the tray; and placing the mail pieces in the tray in an ordered manner so that the edges having dabs will be visible, and the dabs will form a pattern that indicates only the determined number of mail pieces are in the tray.

Abstract: A method for capturing mail piece attributes as well as the number of mail pieces contained in the mailing. This is done by securely capturing an image of the mail piece and its thickness. These mail piece attributes can be used to verify barcode quality, readability, and correctness; presort discounts; address correctness; mail piece size; weight based upon mail piece thickness, indicia attributes, etc. Optionally, light reflectivity sensors can verify the glossiness and contrast of the mail pieces. Images and thickness of mail pieces can be sampled and verified against USPS mailing standards and USPS required documentation.

Abstract: A wireless mailing system that has a minimal number of interface cables between devices, while still maintaining full functionality, is easy to add devices to, and provides remote access for each device without having a dedicated telephone line for each device or having to transport each device to a telephone line is provided. A mailing system includes a plurality of devices, each of which is adapted to communicate with the other devices via a wireless communication link to form a local network. A gateway server can act as the master of the local network to coordinate communication between the devices in the local network, or alternatively, the devices in the local network can communicate directly with each other. Additionally, the gateway server allows remote access to the local network via a standard telephone network or other data network, such as, for example, the Internet.

Abstract: An electronic scale uses an analog signal from a load cell which is converted directly to a pulse width modulated output signal. This pulse width modulated output signal represents the weight of an object on the scale and is sufficient to be directly read by a typical microcontroller. Therefore, no amplifier or analog to digital converter is required. The microcontroller then converts a signal representing the weight of the object on the scale to a weight value. A method of using the counter/timers on the microcontroller with synchronized overflow, is disclosed to enable a high resolution value of the pulse width modulated signal, which is then converted into a weight value for object's weight given that the pulse width modulated output signal is proportional to the weight of an object placed on the load cell.
