  • Patent number: 8532330
    Abstract: A method for enhancing security printing includes generating data for a region of interest (14), where the data includes information for at least one of locating or analyzing the region of interest (14) using a secure registry (18). The method further includes encrypting a deterrent (12) with the data, and printing the deterrent (12) and the region of interest (14) on an object (10).
    Type: Grant
    Filed: May 22, 2008
    Date of Patent: September 10, 2013
    Assignee: Hewlett-Packard Development Company, L.P.

  • Patent number: 7814324
    Abstract: A method for making a patient monitor includes providing an electronic device operatively connected to the monitor. The device is configured to measure predetermined signals from a user and to generate therefrom a substantially unique signature specific to the user. The method further includes storing the signature in the electronic device. The electronic device is adapted to compare newly acquired signatures to the substantially unique signature, and to recognize at least one difference from the substantially unique signature. Recognition of a difference in the signatures signifies a new user, whereupon the electronic device acquires new predetermined signals and generates therefrom a new substantially unique signature specific to the new user.

  • Patent number: 7651665
    Abstract: A microtray for handling biosubstances comprises a fluid holding structure and a fluid ejection structure. The fluid holding structure includes an array of wells with each well configured to contain at least one biosubstance. The fluid ejection structure is in communication with the fluid holding structure and configured to dispense the at least one biosubstance onto a target media.

  • Publication number: 20080131977
    Abstract: A lateral flow device, and related systems and methods is disclosed. A method of building a lateral flow immunoassay device includes dispensing, via a fluid ejection device, a flow-inducing substance to form a flow membrane, and dispensing, via the fluid ejection device, a measured volume of biosubstances from an array of biosubstances to form a sample module, a tagging module, a reaction module, and a waste module on the membrane.
