Patent number: 10402543Abstract: A business model for facilitating the deployment of prescription validation systems into pharmacies is installed in pharmacies for little or no up-front cost to the pharmacy. Instead, the pharmacy is charged on a per use basis, that is, charged every time a prescription is validated in the system. In this way, the system vendor obtains payment on a subscription-like basis. Up-front costs at the pharmacy are avoided. Moreover, risks to a pharmacy concerning maintenance and slow productivity are avoided, or shifted onto the system owner, who is able to assess those risks.Type: GrantFiled: December 31, 2014Date of Patent: September 3, 2019Assignee: VOLCANO CORPORATIONInventor: Petros Kotidis

Patent number: 8467051Abstract: A near infrared (NIR) semiconductor laser system is shown for gas sensing. An embodiment is centered on the use of a system with a much wider tunable laser, which today has a scan band of more than 150 nanometers (nm) to as much as 250 nm or more. In some cases the scan band is about 400 nm or more. This is achieved in the current embodiment through the use of a widely tunable microelectromechanical system (MEMS) based Fabry-Perot filter as an integral part of the laser cavity. Using this technology, these systems are capable of capturing a variety of gases in the any of the well-known spectroscopic scan bands, such as the OH, NH or CH. For example, a single laser with a 250 nm scan band window between 1550-1800 nm can capture ten or as many as twenty hydrocarbon-based gases simultaneously.Type: GrantFiled: March 15, 2012Date of Patent: June 18, 2013Assignee: Axsun Technologies, Inc.Inventors: Dale C.

Patent number: 7875457Abstract: To address counterfeit problems, for example, we propose a secure, flexible, and cost-effective authentication solution that can be integrated into conventional distribution logistic systems. The proposed solution for product authentication and distribution channel validation comprises three major components: 1) machine-readable Raman-active chemical taggant; 2) a taggant reader; and 3) a taggant eraser. The proposed solution is to control and validate the distribution channel by authenticating the origin of products. Authentication is accomplished by verification of distinct taggants associated with the articles, such as on its label, along with other product distribution information in optical, spatial-encoding indicia, such as a barcode. The taggant information is used to identify, validate, and distinguish the origin of the source of the articles, such as goods or products.Type: GrantFiled: May 12, 2005Date of Patent: January 25, 2011Assignee: Axsun Technologies, Inc.Inventors: Xiaomei Wang, Dale C.

Patent number: RE44605Abstract: Integrated spectroscopy systems are disclosed. In some examples, integrated tunable detectors, using one or multiple Fabry-Perot tunable filters, are provided. Other examples use integrated tunable sources. The tunable source combines one or multiple diodes, such as superluminescent light emitting diodes (SLED), and a Fabry Perot tunable filter or etalon. The advantages associated with the use of the tunable etalon are that it can be small, relatively low power consumption device. For example, newer microelectrical mechanical system (MEMS) implementations of these devices make them the size of a chip. This increases their robustness and also their performance. In some examples, an isolator, amplifier, and/or reference system is further provided integrated.Type: GrantFiled: November 5, 2009Date of Patent: November 19, 2013Assignee: Axsun Technologies, Inc.Inventors: Walid A.
