Abstract: Systems and methods for measuring effectiveness of advertisement displays in public areas. A smart sensor box is connected to the display screen incorporating cameras to capture images of the vicinity of the display and individuals within it. A location sensor captures the location of the display. A processing unit identifies and profiles individuals viewing the display based on data captured by the cameras and the location sensors. A communication interface transmits processed data to a central hub and receives feedback from the central hub. The central hub analyses display engagement and profiles of individuals for measuring the effectiveness of the advertisement being displayed and provides feedback for updating the display.

Abstract: Described is a method for producing high purity tantalum, the high purity tantalum so produced and sputtering targets of high purity tantalum. The method involves purifying starting materials followed by subsequent refining into high purity tantalum.

Abstract: A system and method to facilitate computer-based commerce is presented. The system includes a module to facilitate communicating a vendor offering to a user if the offering is within a category designated by the user as being acceptable for receipt of such offering. The provider offering includes a category code to indicate an associated category for the provider offering. If a user chooses to propagate a vendor offering to another user, the user may be entitled to a reward. The reward may be designated to the user or to a third party. A spam control module may also be provided to identify spam complaints and to take actions in response to the spam complaints.

Abstract: A system and method to facilitate computer-based commerce is presented. The system may including a module to facilitate communicating a vendor offering to a user if the offering is within a category designated by the user as being acceptable for receipt of such offering. The acceptable categories may be stored in user profiles, a user profile being updated when the user chooses to add or remove an interest category. When a vendor offering is received, the offering is categorized and stored in an offerings database. The vendor offering is then matched with a category in the user profile When the vendor offering is communicated to the user, the user's address or the user's identity is not revealed to the vendor. If a user chooses to propagate a vendor offering to another user, the user may be entitled to a reward. The reward may be designated to the user or to a third party. A spam control module may also be provided to identify spam complaints and to take actions in response to the spam complaints.

Abstract: Described is a method and apparatus for producing high purity titanium and high purity titanium so produced. The process contemplates producing titanium sponge in a container and performing titanium fused salt electrolysis in situ in the same container to produce high purity titanium crystal, and where especially low oxygen content is desired, to treat the high purity titanium crystal as produced with iodine.

Abstract: A two piece picture frame for carrying and displaying an image carrying sheet in an inner frame, which is detachably secured to an outer frame for sheet installation and removal from the inner frame. The inner frame has corner brackets that are removably held in interlocking engagement with inner framing members, with studs from the brackets extending through a background panel of the outer frame and detachably retained therein by wing nuts.

Abstract: A method is disclosed for producing an anodized film on titanium, its alloys and other metals such that the film deposited will have a specific leak rate of less than one nanoamp per square centimeter at room temperature with an impressed electric field of at least five volts, where the anodization is performed in a solution consisting of liquid ortho-phosphoric acid of reduced water content in an aprotic solvent, and articles of manufacture therefrom.

Abstract: A picture frame assembly which has an outer frame with an inner frame carried on the outer frame background plate with provisions for easy insertion and removal of image-carrying sheets, such as paintings, photographs and other decorative sheets. The picture frame is unique because of the following features. While the inner frame's bottom and side pieces are adhesively attached, the inner frame's top piece is detachably mounted to the inner frame's side pieces. The inner frame is extended further than the outer frame to allow image-carrying sheets to be inserted into the inner frame in a completely flat vertical orientation. The top piece is attached by the wedging of grooves in the each end of the top piece onto tapered corner connectors extending from the side pieces.
