Abstract: A keyboard support includes a support body having a throughpassage that passes through the support body and opens on opposite sides of the support body. The support body also defines a support surface configured to accommodate a keyboard such as a keyboard for inputting alphanumeric symbols to a personal computer. A moveable mouse support fits within a portion of the throughpassage of the support and extends outwardly from the support to define a mouse support surface having a region that extends in front of a front edge of a keyboard with the keyboard resting the support surface. Although the term "mouse" has become almost universally used for the rolling input device used to move an arrow on the display screen and "pick" functions or data values, other terms such as "trackball" can be used interchangeably with the term "mouse".

Title: Multi-level leaching system
Inventor: PRESBY DAVID W
IPC: C02F1/28
Filed: 1999-10-19
Granted: 2004-04-06
Abstract: The invention most fundamentally is a leaching system substantially consisting of subsystems of liquid permeable conduit, serial or parallel interconnected for the serial or parallel flow of fluid being processed. Fluid flow is within subsystems and between subsystems from one level to another level. I.e., the subsystems of which the system is comprised are located at different depths one above the other within a "leach bed" or within the volume designed to process the leached fluid. The leaching system has at least two (2) leaching subsystems wherein each of the leaching subsystems is planarly located at a different depth within the leaching field having the leaching system installed therein. The leaching subsystems are fluid flow connected, using tubing, such that fluid being leached either flows; (1.) sequentially or serially through one of the subsystems and then sequentially or serially through another of the subsystems and subsequently through yet another subsystem until the last of the subsystems; or (2.) the fluid being leached is divided such that the divided portions flow in a parallel paths or substantially simultaneously through one of the subsystems and then subsequently through the remaining subsystems either simultaneously or sequentially and in either sequential flow or parallel flow within the components of the subsystems. The system permits a greater density of bacteria within a leaching area. The multi-level system allows a straightforward installation of a leaching system in small or irregularly shaped areas where installation of effective single level systems would be difficult or impossible.

Abstract: An intraurethral magnetic valve (1) for insertion in the human urethra of a person suffering from incontinence. The intraurethral magnetic valve (1) includes a nonferromagnetic cylindrical housing (2), a valve seat assembly (36) attached to one end of the housing, a spherical magnetic valve element (14) disposed for universal movement in the housing, and a ring (10) for retaining the valve element which is attached at the other end of the housing. The valve seat assembly (36) has a nonferromagnetic valve seat (4) and ferromagnetic ring (5). The valve element (14) is maintained in closed check position against the valve seat (4) by attraction to the ferromagnetic ring (5), restricting the flow of fluid through the valve (1). An external magnet (15) is used to impart magnetic torque and attraction to the valve element (14) displacing it from the valve seat (4) and opening the valve for fluid flow. On removal of the external magnet (15), the valve element (14) returns to its closed check position on the valve seat (4).  The intraurethral magnetic valve (1) may further include a mechanism (14) having a spring (134) for relieving excessive fluid pressure, in which the valve seat assembly (36), rather than being attached to the housing (2), is axially slidable within the housing against the force of the spring (134) when excessive hydrostatic pressure is present to allow release of fluid through a passageway around the valve seat assembly (36).

Abstract: The invention relates to a small arm system with an exchangeable barrel. The aim of the invention is to provide a small-caliber small arm for high-speed bullets (10) with an effective silencer. To this end, the arm is provided wi th an exchangeable barrel that is designed for a bullet (10') whose caliber is substantially larger than the bullet (10) for the small caliber but which ha s the same length and the same base dimensions. The bullet (10') for the exchangeable barrel is designed in such a manner that the projectile (7') ha s a muzzle velocity in the ultrasonic range while being sufficiently heavy to supply a sufficient muzzle energy. The different bullets (10, 10') for the original barrel and for the exchangeable barrel are designed differently so that a confusion of the bullets (10, 10') is impossible since the respective bullets (10, 10') cannot be completely inserted into the bullet chamber (20, 20') to which they do not pertain.

Title: Transmission of mobile unit requests in wireless uplink systems
Inventor: LAROIA RAJIV
IPC: H04L12/28
Filed: 2001-04-23
Granted: 2005-06-07
Abstract: Access request transmissions are effected in a wireless communications system by assigning each mobile unit a unique dedicated uplink resource. Specifically, each mobile unit is assigned channel segments with distinct time slot indices and/or waveform indices, where waveforms with distinct indices are orthogonal. A base station can identify the mobile that has made an access request from the dedicated uplink resource. Therefore, no mobile identification number is needed in the uplink request message. Then, the base station can transmit a request response message on a shared downlink resource that may include the identification number of the requesting mobile unit to acknowledge reception of the request. The mobile unit may transmit on a shared uplink resource an acknowledgment of reception of the downlink request response message.
