Abstract: 3D glasses having an RFID tag (embedded in one or more temples) are rented to theater or other venue operators. The glasses are shipped to a venue for distribution to patrons and collected from patrons in the trays. Inventory and other measures are implemented by RFID scanning while the glasses are in the trays (e.g., upon delivery to a theater, on collection from the theater, upon inspection at the 3D rental company, etc). Data gathered from RFID scanning and inspections allows the rental company to properly allocate rental costs to various venues based on shrinkage which includes, for example, extraordinary wear of the glasses, breakage or theft, which is attributable and traceable to the specific venues. The theater or venue may also independently scan the trays upon delivery and pick-up to maintain their own records. The invention includes 3D glasses with RFID, a washing rack, and rental systems.

Abstract: RFID data is utilized for billing and management of 3D glasses in a cinema theater or group of theaters. RFID pedestals identify privately owned or rented 3D glasses brought into a theater by a customer. An invoice is automatically generated billing the theater operator for the use of the 3D glasses. Usage of the glasses along with other data collected about the customers is utilized for targeted advertising (e.g., e-mails, texts, selected advertise in pre-show, etc.). The invention reduces up front cost in installing a reusable 3D glasses system.

Abstract: A system 8 for delivering stereoscopic images for viewing without 3-D glasses being required comprises a video display element 1, an image direction element 4, a front holder element 5, a rear holder element 3, and a resolution enhancement element 2. The video display element 1 outputs a plurality of left-eye images and a plurality of right-eye images. The image direction element 4 directs each left-eye image at a desired left-eye angle and directs each right-eye image at a desired right-eye angle. The front holder element 5 is movable relative to the rear holder element 3 to move the image direction element 4 to adjust each left-eye angle at which each left-eye image is directed and to adjust each right-eye angle at which each right-eye image is directed to suit each viewer. The resolution enhancement element 2 is modulated simultaneously with the image direction element 4.

Abstract: A portable tamper article is disclosed, including a non-flammable tamper device, and a retaining member secured to or integrated with the tamper device, said retaining member adapted to engage a portable device. Also dislcosed is a portable tamper article, including a non-flammable retaining member comprising a tamper device, wherein the retaining member is adapted to engage a portable device. Further dislcosed is a combination lighter and tamper article, including a lighter and a retaining member comprising a tamper device, wherein the retaining member is adapted to engage the lighter.

Abstract: Systems and methods for providing surge protection to turbine components are provided. A surge protection limit may be determined for the turbine component. One or more measurements associated with operation of the turbine component may be received and provided to a cycle model executed to predict an operating condition of the turbine component. The predicted operating condition of the turbine component may be adjusted based at least in part on the received one or more measurements. The surge protection limit may be adjusted based on the adjusted predicted operating condition of the turbine component.

Abstract: A novel method of packaging fixed-temple eyewear includes arranging a first plurality of pairs of fixed-temple eyewear in a first arrangement with the lenses of the eyewear lying substantially in the same plane. The right temples of the eyewear are aligned along a first line and the left temples of the eyewear are aligned along a second line. The first plurality of pairs of eyewear is held in the first arrangement with a first portion of packaging material. Second and third pluralities of fixed temple eyewear are similarly arranged in second and third arrangements, respectively. The first, second, and third arrangements of fixed-temple eyewear are engaged with one another in a space saving relationship and packaged. Packages of fixed-temple eyewear are also disclosed.

Abstract: 3D glasses including features for an enhanced viewing experience with lower production and operating costs for theaters. Keyed lenses and removable temples facilitate assembly and field repairs. Specific angles of lens placement and the provision of specific anti-reflective areas on the frames enhance the quality of the optical path content being viewed. RFID and radio chips increase accountability and collection of use statistics. Smooth areas enhance cleaning and lower the time and material costs for between use cleanings.
