Abstract: A personal protective device (PPE) including a face cover assembly and a bodysuit configured to be worn by a human user. The device protects users against airborne aerosol particles containing viruses or other infectious agents while enabling improved flexibility relative to prior art designs. The device includes a helmet-like” rotating face cover assembly that fits over the user's head and attaches to a collar on the biohazard bodysuit. This rotating face cover assembly has a plurality of different mask sides, each with differing geometries or other properties. The device enables a user to rotate (either manually or by electric motor) the masks and select a given mask side that best meets that user's needs. The different mask sides can accommodate different facial geometries, eyewear types, and use cases, such as operation in more hostile environments.

Abstract: A graphical user interface which employs logical barriers for temporarily preventing cursor movement between graphical elements under certain circumstances.

Abstract: A computer-implemented system and method for navigating through a plurality of graphical elements with a trackball. For example, a method according to one embodiment of the invention comprises: detecting a substantially vertical motion on the trackball when a first element is selected; and responsively selecting either (a) a second element which is closest vertically to the first element or (b) a third element in the same horizontal line as the first element if a leftmost horizontal coordinate of the third element is closer to a leftmost horizontal coordinate of the first element than then leftmost horizontal coordinate of the second element.

Abstract: Methods and apparatuses for processing media data transmitted in a data communication medium. A digital processing system is provided with a time related sequence of media data provided to the digital processing system based on a set of data, wherein the set of data indicates a method to transmit the time related sequence of media data according to a transmission protocol. The set of data, itself, is a time related sequence of data associated with the time related sequence of media data. The time related sequence of media data may be presented and/or stored by the digital processing system.

Abstract: A method of forming a bottle-shaped or other contoured metal container by subjecting a hollow metal preform having a closed end to internal fluid pressure to cause the preform to expand against the wall of a die cavity defining the desired shape, and advancing a punch by means of a backing ram into the die cavity to displace and deform the closed end of the preform either before or after expansion begins but before it is complete. The pressure-subjecting step is performed by simultaneously subjecting the preform in the die cavity to independently controllable internal and external positive fluid pressures and varying the difference between them to control strain rate. Apparatus for performing the method includes a split die with plural split inserts disposed in tandem to define the die cavity wall and heaters respectively inserted within the preform and arranged to heat the backing ram.

Abstract: A method of forming a bottle-shaped or other contoured metal container by subjecting a hollow metal preform having a closed end to internal fluid pressure to cause the preform to expand against the wall of a die cavity (10) defining the desired shape, and advancing a punch (12) into the die cavity (10) to displace and deform the closed end of the preform either before or after expansion begins but before it is complete. The pressure-subjecting step is performed by simultaneously subjecting the preform in the die cavity to independently controllable internal and external positive fluid pressures and varying the difference between them to control strain rate.
