  • Apparatus and methods for optical representations of radio frequency identification tag information
    Patent number: 7513436
    Abstract: Methods, systems, and apparatuses for reconstitution of data for failed radio frequency identification (RFID) tags are described. The tag's information is segmented, optionally compressed, and encoded into a plurality of optical representations. Alternatively, or in addition, a portion or all of the tag's information is stored in a non-optical format. Upon failure of a tag read for any reason (e.g., tag failure, reader failure, operator error, environmental reasons, etc.), the data is reconstituted from the optical representations. Alternatively, or in addition, the reconstitution includes incorporating the information stored in a non-optical format.

  • System and method for mobile biometric authentication
    Patent number: 7512254
    Abstract: Described is a method and system for authenticating identity of a person using a portable device. The portable device may includes an imager, an image processing unit and a processor. The image processing unit reads encoded data in a first image from an imager of the device. The image processing unit extracts a portion of a second image from the imager to generate extracted portion data. The extracted portion of the second image corresponds to a portion of a person whose identity is to be authenticated. Stored biometric data for a person is located based on the data read from the first image. The processor compares the extracted portion data of the second image to the stored biometric data for a person.

  • Color image projection system and method
    Patent number: 7511771
    Abstract: An image projection system projects an image on a projection screen having phosphor particles for converting incident violet light into green light which, together with red and blue light, creates the image in full color. The phosphor particles are bound in a binding material whose index of refraction matches the index of refraction of the phosphor particles to reduce back scattering of light.

  • Optimizing RFID Reader Duty Cycle Or Power To Preserve Battery Life
    Publication number: 20090079571
    Abstract: The duty cycle of a portable battery-powered RFID tag reader is reduced during time periods when it is less likely to produce a “read” in order to preserve battery life. The reader operates with an aggressive duty cycle during periods of a high probability of a tag read and reduces duty cycle during periods of a low probability of a tag read. In this manner a user does not perceive the reader to be sluggish. An alternative embodiment reduces peak operating power during time periods when a tag is less likely to produce a “read” in order to preserve battery life.
