  • Patent number: 7544190
    Abstract: Bioactive agents are cutaneously delivered by a jet dispenser using inkjet technology, such as that used in printing. The dispenser propels precise volumes of bioactive agent toward the skin, where they exert a local or topical effect, or move through the skin for transdermal systemic delivery. Drugs are either delivered directly to the skin, or are introduced into a transdermal patch, which may receive repeated dosages. A controller in the dispenser may control delivery of multiple different drugs, timing of drug administration, or change drug regimens in response to a changing medical condition of a patient, such as those monitored by a sensor in communication with the controller, for example to prevent an overdose. The dispenser may act as an electromechanical patch, capable of long term administration of drugs to the skin, to achieve local or systemic pharmaceutical effects. Administration methods are also provided, along with replacement kits.

  • Patent number: 6848779
    Abstract: A label making inkjet printer applies print imaging directly to the adhesive side of a media provided in sheet-form and in reel-form. Because inkjet printing is a non-contact printing method, print imaging may be applied to the adhesive side of the media According to one embodiment, a user manually pulls tape-form media through the printer while encoding signals detect linear movement of the media and provide basis for synchronizing operation of an inkjet print head. According to another embodiment, a motorized media transport carries tape-form media on a pair of media transport belts past an inkjet print head. The resulting adhesive label when applied to a contact surface substantially disappears due to its transparent nature leaving visible only print imaging applied thereto and captured between the protective tape media and contact surface therebelow.

  • Patent number: 6653810
    Abstract: A motor controller circuit for controlling an electric motor in response to motor commands from a host controller. The controller circuit includes a motor driver circuit for providing motor driver signals to the motor in response to motor driver commands. A control logic circuit is responsive to command words from the host controller for generating motor drive control signals, the controller has an associated motor identification, each command word having associated therewith a motor identification portion and a motor command portion. The control logic compares the motor identification portion of the command word to the motor identification, and converting the motor command portion into motor driver control signals if the motor identification portion corresponds to the motor identification. Multiple motors can be interfaced to a host controller, either in parallel or in a cascaded manner. Each motor has an unique address, and can interpret a command word and execute a command addressed to the motor.

  • Patent number: 6414701
    Abstract: A printing media cartridge for a drum-type hard copy apparatus has printing media supply within the drum. Printable sheet lengths of printing medium are extracted from the interior of the drum through a slot such that individual prints can be produced using the drum outer surface as a platen. Removing a print from the platen extracts the next sheet length from within the drum which is then automatically wrapped back onto the drum's outer surface and aligned for the next print cycle. Printer control encoding is provided with the cartridge.

  • Patent number: 6208719
    Abstract: A method and apparatus for telecommunications having automatic network adaptations and silent mode operations are demonstrated. An integrated telecom device includes a programmable controller and memory adapted to receive telecommunications carrier rate information updates or system synchronization without requiring subscriber instigation or intervention procedures. Rate provider access, or subscriber programmed caller access, is recognized prior to signaling to the subscriber that an in-coming transmission is in progress and rate database updates, or other desired transmission from the programmed caller, are received automatically. In order to obtain least-cost routing of out-going transmissions, the subscriber merely inputs the destination telephone number or other destination code. In-coming transmissions from a rate provider or preselected advertising entities can be programmed for silent mode reception.

  • Patent number: 6097405
    Abstract: A detection apparatus for use in printing devices is disclosed including a container for storing a printing composition, a light source, a light detector, and a light waveguide. The waveguide conducts light from the source to the detector which is configured to enable printing by the device when the light from the source is detected. The detection apparatus may also, or alternatively, be configured to enable printing when either or both the container is coupled to the device in a printing orientation and/or the container with a printing composition having a particular characteristic is coupled to the device. In such configurations, the waveguide fails to conduct light from the source to the detector when the container is not in the printing orientation and/or the container with the particular characteristic is disconnected from the device.

  • Patent number: 6065828
    Abstract: An ink replenishment system for an inkjet printing mechanism has an ink reservoir that is removably receivable by the inkjet printing mechanism to deliver an ink composition to an inkjet printhead for printing. The ink reservoir contains a large volume of colorless ink vehicle and one or more smaller containers of colorant or other ink components separate from the vehicle. At the time of desired use, a user makes a selection which activates the selected colorant and/or other ink constituent to mix with the vehicle to produce the desired ink composition. This ink replenishment system may be used in a replaceable inkjet cartridge ink dispensing system, or in an off-axis ink dispensing system, and a method of accomplishing such ink replenishment is also provided.
