A flexible cover has laterally opposing edge portions with intermittent retainers received in the guide rails. The retainers are configured to slide relative to the guide rails between first and second positions within the opening in response to actuation of the drive system. Multiple spaced apart bows extend laterally between guide rails. The bows provide a laterally and outwardly extending arc that maintains tension on the flexible cover laterally between the retainers.

Abstract: Methods, systems and methods for designing a system that provides adaptive control and adaptive predictive filtering using nonlinear components. A system design is described that provides an engineered architecture. This architecture defines a core set of network dynamics that carry out specific functions related to control or prediction. The adaptation systems and methods can be applied to limited areas of he system to allow the system to learn to compensate for unmodeled system dynamics and kinematics. Two types of adaptive modules are described which are configured to account for the unmodeled system dynamics and kinematics.

Abstract: A needle shield comprises an elastomeric sheath having a closed distal end and an open proximal end. The distal end is configured to form a first seal with a distal tip of a needle in an initial position. The proximal end is configured to form a second seal with a syringe body in the initial position. The second seal is configured to release from the syringe body prior to the first seal releasing from the needle when the elastomeric sheath is moved distally from the syringe.

Abstract: The invention relates to an arm actuated lever for a multiwheeled cycle. In the preferred embodiment, the invention is a braking system including a braking means associated with one or more of the wheels of the cycle and a brake lever for the purpose of engaging the braking means which is attached to the hand pedal of the bike in a manner that permits the brake lever to be engaged by the operator's wrist or forearm for use by quadriplegics. . The brake lever is further configured to rotate with the hand pedals and crank arms of the cycle which are engaged by the rider's hands through the pedals. The invention permits the cranks to rotate forwardly to deliver power to the wheels and to freewheel in an opposite rotation to permit free coasting. Movement of the operator's wrist and or forearm provides movement to the brake lever engaging the braking means and stopping of the handcycle.

Abstract: Methods, systems and devices for broadcasting messages of different packet formats in interleaving fashions, wherein a transmitter may broadcast a first packet in a first format configured to be well-suited for a first software implementation of a receiver and broadcast a second packet in a second format that is associated with a second software implementation (e.g., firmware, application, etc.). The receiver may receive and process the first packet to detect information that indicates the presence of messages of the second packet type, adjust the receiver (i.e., change a behavior of the second software implementation) in response to detecting information, receive and process the second packet via the second software implementation, and perform an action based on the processed second packet. In some embodiments, the first and/or second messages may include portions of data that may be combined by the receiver.

Abstract: Methods, systems and apparatus that provide for perceptual, cognitive, and motor behaviors in an integrated system implemented using neural architectures. Components of the system communicate using artificial neurons that implement neural networks. The connections between these networks form representations—referred to as semantic pointers—which model the various firing patterns of biological neural network connections. Semantic pointers can be thought of as elements of a neural vector space, and can implement a form of abstraction level filtering or compression, in which high-dimensional structures can be abstracted one or more times thereby reducing the number of dimensions needed to represent a particular structure.

The frame is configured to place the operator's center of gravity in a position of falling away from the frame, lever arms, foot platforms and providing a torso support enabling the operator to be supported by hanging from the hands and supported by the feet and torso support. The frame may be rotated through varying angles from vertical permitting the operator's center of gravity to fall away from the frame and allow the operator to hang away from the frame further enhancing the climbing experience.

Abstract: A deposition process involves the formation of multicomponent semiconductor layers, in particular III-V epitaxial layers, on a substrate. Due to pyrolytic decomposition inside the reaction chamber, one of the process gases forms a first decomposition product. Together with a second decomposition product of a second process gas, the decomposition products form a layer on the surface of a heated substrate and also adhere to surfaces of the process chamber. To remove these adherences, during an etching step a purge gas containing a reactive substance formed by free radicals is introduced into the process chamber. The etching step may be performed before or after the deposition process.
