Abstract: Provided is window mull assembly and method for connecting two or more windows at the site of installation and immediately prior to installation. The window mull can be applied to any configuration of window, including casement, awning, single hung, double hung, picture windows, and the like. The window mull assembly may include a mull mechanism having a first strip and a second strip. Each strip may include a window-mating face that attaches to a vertical profile of a corresponding window frame and a strip-mating face. The strip-mating face of each strip may engage with one another. Each strip-mating face may include a brace and an angled projection. The strips may be substantially identical but oriented in the corresponding window frame in opposite directions so that the angled projection of each strip extends in an opposite direction and may engage with one another in a hook like manner.

Abstract: The invention relates to medical implants, including spinal implants and bone grafts, for fixation and integration with hard tissue. The bone medical implants include at least one rotational fixation mechanism that further includes or is attached to one or more sharp protrusions configured to penetrate and become lodged into hard tissue to provide support and positional stability. Such support is useful to ensure that the spinal bone graft may be used without additional stabilizing or anchoring structures, such as supporting plates or screws.

Abstract: A lockable sliding door is described. A ratcheted track allows the movable panel of the door to be selectively locked in both closed and vented positions. A lever is positioned along a midpoint of the movable panel to allow for the easy engagement of the locking mechanism. Further, the locking mechanism is carried on the movable panel. The technology is configured to allow the sliding door to be locked in various configurations, with the door partially opened, completely open, or completely closed. The technology may also be utilized on windows or any other architectural features with a slide-to-open and close design.

Abstract: A system for authenticating a document, D. A trusted party applies an algorithm to D, for example, by treating each byte of data within D as a number, and treating the numbers as inputs to the algorithm. The trusted party obtains a result from the algorithm, termed a Message Authentication Code, MAC. The trusted party gives a courier both (1) D and (2) the MAC, as by loading both into a portable computer carried by the courier. The courier delivers both D and MAC to a recipient, who is equipped with the identical algorithm. The recipient applies the algorithm to D. If the recipient obtains the MAC, the recipient concludes that no tampering of D occurred. The reason is that successful tampering requires the courier to replace MAC with a fabricated MAC(fab). MAC(fab) must possess the characteristic that the algorithm would produce MAC(fab) when applied to the tampered document D.

Abstract: A process for preparing ultrafine powders of biological macromolecules comprises atomizing liquid solutions of the macromolecules, drying the droplets formed in the atomization step, and collecting the particles which result from drying. By properly controlling each of the atomization, drying, and collection steps, ultrafine dry powder compositions having characteristics particularly suitable for pulmonary delivery for therapeutic and other purposes may be prepared.
