Abstract: An apparatus and method for secure data deletion. The apparatus includes an enclosure, a connector for communicatively coupling to a computing device, a storage medium disposed within the enclosure and communicatively coupled to the connector, and self-contained software disposed on the storage medium. The software is configured to execute, on a processor, the steps of selecting for deletion files disposed on storage media accessible on the computing device, and performing a secure deletion action on the files. The software is further configured to execute the step of performing a deep scan for each file of the selected files. The deep scan includes canning storage media accessible on the computing device for files similar to the file, wherein files similar to the file are reformatted, duplicate, edited, changed, modified or similar files.

Abstract: An ice cube tray assembly having an insulating box, a lower chamber and an upper chamber. The insulating box having a base and an upstanding structure, with a cavity. A top surface has an inner and outer perimeter, with the inner perimeter defining the opening of the cavity. The lower chamber includes an upper deck portion and container structure depending therefrom. The upper chamber includes a top wall and an inner container structure depending from the top wall. The upper and lower chambers are positioned in sealing engagement.

Abstract: A demountable structure system is disclosed. The demountable structure system may have a roof system positioned atop one or more structural panel(s) and a floor system positioned beneath one or more structural panels(s). The structural panels may have different shapes, configurations, and features, and may support the roof system in order to form a demountable structure. Alternatively, the roof system is omitted and a wall or other structure can be formed from the structural panels. Each structural panel may have other features, such as finish panels, fabric panels, accessory mounts, recessed lighting, electrical outlets, etc. Some structural panels have sound dampening features, such as to form portable musician's sound booth. Thus, a structure may be formed which is both readily disassembled, yet also sturdy.

Abstract: Technology is described for a system to provide skill training in various fields, including professional fields involving hand-held instruments. The system senses a user's manipulation of an instrumented work piece, handheld instrument or tool using various sensors, e.g., for a dental tool, an array of pressure sensors in the instrumented work piece and/or the tool's tip, grip sensors, and sensors to track the position and movement of the tool and/or work piece relative to each other. The system includes lessons to train users in the proper methods to manipulate the instrumented work piece and/or the tool and provides guidance and feedback based on the user's performance to build the user's skills, prevent injury, and document competency.

Abstract: A posting module enables a user to specify information for a first date posting, including a first date venue. Optionally, a database is accessed and information related to the first date venue is received. The first date posting is optionally populated with information specified by the first user and at least a portion of the information received via the database. A search engine may identify the first date posting at least partly in response to an action of a second user, and provide the first date posting for display to the second user. A module is configured to cause an invitation control to be displayed to the second user in association with the first date posting, detect the second user activating the invitation control, and cause an invitation, to go on a date corresponding to the first date posting of the first user, to be presented to the first user.

Abstract: A device for isolating DNA from a sample containing cells, including a cartridge having an entrance port and an exit port, a membrane disposed between the entrance port and the exit port, and a plurality of channels between the membrane and the exit port. Additionally, systems and methods for isolating DNA from a sample containing cells and also systems and methods for amplifying and isolating single-stranded DNA from a sample containing DNA.
