Abstract: A renal therapy system is disclosed. In an example, the renal therapy system includes a home renal therapy machine that stores, to a log file, dates of when renal therapies were performed and a type of each renal therapy that was performed. The system also includes a server that receives the log file from the home renal therapy machine. The server compares the dates and types of performed renal therapies stored in the log file to a device program that specifies dates for performing renal therapies and the types of renal therapies to be performed. The server displays a flag in a user interface of a clinician computer when there is a deviation from the comparison.

Each serrated blade has a centroid located along the longitudinal axis.

Abstract: A cerumen protection plug for a hearing device. The cerumen protection plug prevents cerumen from passing along a sound conduit in the hearing device and blocking sound output from a receiver in the hearing device. The cerumen protection plug includes a circular plug containing a cerumen barrier. A positioning handle allows the cerumen barrier to be positioned along the sound conduit, where it prevents cerumen that has entered the sound conduit from traveling along the sound conduit to the receiver or an output port of the receiver.

The tool comprises an insertion tip and an removal tip, both configured to fit inside the sound conduit and to couple or engage with an engagement body extending centrally from the cerumen filter. The tool may be in the form of a stylus with the insertion tip on one and the removing tip on the other end. The tool may also be in the form of a disc dispenser with a plurality of insertion and removal tips attached to the dispenser and accessible for use by rotating plates making up the disc dispenser.

Abstract: A golf practice aid (10) for establishing a circular pattern about a golf cup (C) includes a disk (12) sized to fit into the mouth of the cup. Radial lines (24) formed on the disk are evenly spaced about the disk and extend from the center to an outer edge thereof. A cord (16) of a predetermined length is tethered to the disk and is extendible outwardly from the disk to be sequentially drawn along each line, with a a marker (M) placed adjacent the outer end of the cord when the cord is fully extended. By extending the cord successively along each radial line, a circular pattern of a defined radius is formed by the markers placed about the cup, the circular pattern assisting golfers in practicing their putting, chipping, pitching, and bunker pay skills in accordance with a method of the invention.

Abstract: A practice aid for use by a golfer practicing hitting a golf ball (B) out of a sand trap. A disc (D) of predetermined diameter is placed on the top of the sand (S) with its leading edge either touching the underside of the golf ball or resting slightly behind it. When practicing a bunker shot, the golfer swings their club so it enters the sand immediately behind the trailing edge of the disc and passes through the sand beneath both the disc and the golf ball. The force imparted to the sand by the club causes the ball to fly out of the bunker on a cushion of sand. The disc provides an indication to the golfer as to how far behind the golf ball their club should enter the sand in order to hit the golf ball out of the sand trap.

Abstract: An process for producing thin silicone by extrusion of a layer of silicone. The silicone layer may be extruded onto a substrate layer. The silicone layer and the substrate layer may be extruded together out of an extrusion die.

Abstract: A turbocharger having a variable geometry turbine inlet incorporates a piston movable to vary the area of the inlet nozzle into the turbine. Vanes extending from the heat shield for flow control in the nozzle are engaged by the piston in a first closed position. In a second open position, the piston is spaced from the vanes increasing the inlet nozzle area.

Abstract: Apparatus (10) and a method for rendering a weapon (12) incapable of use unless authorized by a specified individual. More than one person may be authorized to use the weapon, however only one person may be authorized to use it at any one time. Each authorized person carries a badge (14) or other device which includes an rf transmitter (TAU) capable of transmitting a coded signal to a receiver (REU) installed in the weapon in response to a coded query from a unit (EU) installed in the weapon. If a properly coded transmission is received by the weapon, it becomes capable of being fired by the person who authorized its use. However, the weapon will not fire unless the person using the weapon is also standing behind the weapon. This prevents the weapon from being turned on the person authorized to use it. The apparatus stores details of the weapon's use (e.g., who, when, and where). This information is released upon receipt of an authorized code.

Abstract: A system for providing users of cellular, PCS, and wide-area wireless handsets with quick and short access to local and global information, based on the user's preferences and location. The invention provides a quick link between wireless handset and dedicated information database. Information database is updated constantly by an array of Information Scanners, which run on Internet hosts. The Information Scanners scan Internet web portals, sites, and servers and filter required data into the dedicated info database. The final connection link is between the wireless handset and the Information Scanner array.

Abstract: The invention concerns a turbocharger with a variable geometry turbine comprising a mobile cylindrical piston (70) to modify the cross-section of the input nozzle to the turbine. Vanes (90) extending from a heat shield (92) for adjusting the flow of the nozzle are contacted by the piston in a first closed position. In a second open position, the piston is spaced apart from the vanes, thereby increasing the input nozzle cross-section.

Abstract: This invention relates to an arrangement for sealing a closed chamber in which equipment is to be replaced and especially to a chamber in which equipment is to be replaced while the chamber is to be maintained closed. The arrangement includes a channel filled with a fluid, such as water, and a skirt arranged to extend into the fluid to form the seal. As the skirt extends down into the liquid, a portal space is formed at the opening in the chamber and the opening preferably includes a gate for closing the chamber from the portal space and the outside.

Abstract: A method for controlling the current profile for current supplied to each phase of a poly-phase switched reluctance motor when a respective phase of the motor is active. The interval each motor phase is active is determined as a function of motor operating conditions, as is a desired profile of current flow into and out of a phase winding (W) associated with the phase. The current profile has an initial portion (Z1) in which current flows into the winding from an initial value current value to a peak current value (I.sub.p). It also has a terminal portion (Z3) including current cut-off to the winding with current in the winding being either stored or dissipated prior to the phase becoming inactive. There may also be an intermediate portion (Z2) occurring between attainment of the peak current and the beginning of the terminal portion of the current profile.
