20080295317 | PROCESS FOR MANUFACTURE OF A LOW COST EXTRUDED AND LAMINATED MICROSTRIP ELEMENT ANTENNA - Methods, systems, and apparatuses for automated manufacturing microstrip element antennas is described. The microstrip element antenna comprises a printed circuit layer, a dielectric layer and a ground plane layer. Mass manufacturing process for such microstrip element antennas without any substantial manual assembly process is described. Automation of the manufacturing steps leads to lower production costs, faster production and a higher yield. | 12-04-2008 |
20080297417 | LIGHT WEIGHT RUGGED MICROSTRIP ELEMENT ANTENNA INCORPORATING SKELETON DIELECTRIC SPACER - Methods, systems, and apparatuses for manufacturing light weight microstrip element antennas incorporating a skeleton dielectric spacer instead of a regular solid body dielectric spacer is described. The microstrip element antenna comprises a radiator, a dielectric layer which is in the form of a skeleton rib-caged structure and a ground plane layer. Due to the skeleton rib-caged structure of the dielectric spacer, design flexibility in terms of a non-uniform variation of the effective dielectric constant across various dimensions of the dielectric layer is obtained. Additional advantages of such a dielectric spacer include a wider choice of materials from which the antenna can be made, overall light weight and low production time and machine cost due to lower cooling time of the dielectric. Further, an antenna with a skeleton dielectric spacer further has a better drying characteristics in an event of a water ingress during or post-production. | 12-04-2008 |
20090322706 | INFORMATION DISPLAY WITH OPTICAL DATA CAPTURE - Systems, devices, and/or methods that facilitate information display with optical data capture are presented. A display surface comprises optically selectable materials and/or contact transparent materials. The disclosed subject matter facilitates displaying information on a surface and collecting optical information about objects interacting with the display surface. The collected optical data, at least in part, is used in determinations related to updating display information. Additional sensors can be incorporated into the system to provide additional information that can be employed in determinations relating to updating display information. | 12-31-2009 |
20110121075 | METHOD AND APPARATUS FOR AUGMENTING OPTICAL BARCODE SCANNER WITH RFID READER - An apparatus and method for augmenting an optical barcode scanner. The apparatus comprises an accessory module that includes an RFID reader, a body part attachable to the optical barcode scanner, and an interface connector for forming a communication link between the RFID reader and the optical barcode scanner when the interface connector is connected with the expansion port of the optical barcode scanner. | 05-26-2011 |
20110128128 | METHOD AND APPARATUS FOR IMPROVING RFID TAG READING - An apparatus and method for improving RFID tag reading. The apparatus includes a substrate element having a predetermined active area, and a plurality of resonant elements each having a resonant frequency, a quality factor, and a response band. The resonant elements are distributed within the predetermined active area of the substrate element for scattering interrogation electromagnetic waves radiated thereupon from the RFID reader. At least one resonant element has a null-direction thereof orientated in a direction that is substantially orthogonal to a line extending from a center of the resonant element to a center of an antenna of the RFID reader. | 06-02-2011 |
20110130085 | METHOD AND APPARATUS FOR IDENTIFYING READ ZONE OF RFID READER - An apparatus and method for identifying the read zone of an RFID reader. The apparatus includes a supporting sheet, a reader-position mark on the supporting sheet to indicate a recommended location to position an RFID reader, and a zone-boundary mark on the supporting sheet to indicate a read zone of the RFID reader with a predetermined field strength. | 06-02-2011 |
20120075101 | RFID Reader With Motion Detection - A technique for operating a Radio Frequency Identification, RFID, reader with motion detection includes detecting a motion in proximity to the RFID reader, and triggering the RFID reader to read any tags in proximity to the RFID reader in response to detecting a motion in proximity to the RFID reader. Detecting a motion can also generate a change in digital signage, or communicate information about read tags to a local area network. Operating this system only when motion is detected saves battery life. | 03-29-2012 |

20140285324 | DETERMINING MOVEMENT OF A RADIO FREQUENCY IDENTIFICATION TAG USING A PHASE DIFFERENCE/FREQUENCY MODEL - Determining movement of a Radio Frequency Identification (RFID) tag first establishes a phase difference/frequency model comprising a set of phase-wrapped local rates-of-change and an intercept point. RFID tag readings are then made to measure phase differences between the interrogation signal and the tag response at different frequencies. A correlation is determined between the measured phase differences versus frequency and the phase-wrapped local phase rates-of-change of the phase difference/frequency model. If the correlation is better than or equal to a predetermined limit, the tag is stationary, or if the correlation is worse than the predetermined limit, the tag is moving. | 09-25-2014 |
