Title: Slide stop, trigger device and grip for a weapon
Inventor: DOLL STEFAN
IPC: F41A17/58
Filed: 2008-02-21
Abstract: The present invention relates to a pivotal latch (21) for a trigger device of a firearm, particularly a rapid-fire weapon, comprising a breech (3) and a safety mechanism (40). The pivotal latch (21) is displaceable between a locking position locking the breech (3) and a position not locking the breech, and comprises a safety element (101; 201) that is displaceable relative to the pivot latch (21) between an idle position (II) and a safety position (I). Said element assumes the safety position (I) when the breech (3) pushes against the pivot latch (21) if the breech (3) exerts an actuating force on the safety element (101; 201) in the forward direction.  In said position (I), the element engages on the safety mechanism (40) if said safety mechanism assumes the safety position thereof at the same time and fixes the pivotal latch (21) itself in the locking position. Otherwise, however, the safety element assumes the rest position (II) and releases the pivotal latch (21). The invention further relates to a trigger device, a grip having such a trigger device, and a corresponding firearm.

Abstract: This motorized, fully automated device remedies the obvious security and thermal deficiencies of glass windows in buildings generally. These R-25 insulated panels (minimum) are designed to close snuggly with their insulated frame -- which is thermally bonded to the building around the respective window in retrofits, and is built-in to new construction projects -- thus optimizing building thermal efficiency, while enhancing security impenetrability. Acting as an awning in the raised position, the panels shield direct sunlight into the window. Both models, for large windows (Fig.3) or for small windows (Fig.10), close and open on demand by electric switch; or open manually by crank, in no-power mode; they are also fully automated, cycling according to pre-programming -- usually from dusk to dawn, or when building unoccupied.  Specialty models will accommodate more intense requirements such as in the far north, hurricane zones, or inordinate crime-risk areas for example.

Abstract: Multiple electrode contacts make electrical connections to the anterior and/or posterior chest for multivariate characterization of the electrical activation of the heart. A central processing unit derives synthetic composite electrographic signals as well as flag signals for specific purposes. A  preferred embodiment uses this system to trigger or gate magnetic resonance imaging, eliminating or reducing problems from small or inverted R-waves, lead detachment, noise, flow signal, gradient changes, and rhythm changes, more reliably flagging the onset of electrical activation of the ventricles. Additional derived data are ST-segment shifts, filling times, and respiratory cycle. Filling times may be used for greatly improved imaging in the presence of rhythm disturbances, such as atrial fibrillation.  Respiratory cycle may be used as a respiratory trigger to control for the effects of breathing on the heart position and image quality.

Title: System and method for signal reception and distribution
Inventor: JEFFERY ROSS
IPC: H04N21/436
Filed: 2010-08-18
Abstract: A system and method for receiving and distributing an over-the-air signal over a network. At least one antenna receives an over-the-air signal containing a plurality of channels, at least one tuner isolates from the over-the-air signal information associated with a selected channel and produces an intermodulated carrier wave associated with the selected channel, at least one demodulator demodulates the intermodulated carrier wave to produce a data stream in a first format. Optionally a processor (for example a transcoder) converts the data stream in a first format into a second format. A    communications interface produces a network transport stream from the data stream in the second format and distributes the network transport stream over the network. A line coupling unit (LCU) sets resistance/capacitance values which optimize the signal for distribution.

Abstract: A painter's tape is formed with a first portion and an adjoining second portion separated by a line of weakness that permits the first and second portions to be physically separated. The painter' s tape has a layer of adhesive on one side with a removable protective strip attached to the adhesive layer on the second portion. The tape is folded along the line of weakness and applied to a first surface with the line of weakness defining a paint line between adjacent first and second surfaces. After painting the second surface, the protective strip is removed to expose the adhesive layer on the second portion, which is then flipped over to adhere to the previously painted second surface. The first portion is then removed by separating from the second portion along the line of weakness leaving the second portion to protect the second surface while the first surface is painted.
