Title: Method and system for controlling access of a subscriber station to a wireless system
Inventor: IBANEZ MARC BENEDICT
IPC: H04W72/08
Filed: 2001-04-02
Abstract: A method for controlling access of a subscriber station to a wireless communications system facilitates the maintenance of a performance target of the reverse link and desired geographic coverage of the reverse link. The method for controlling access of a subscriber station to a wireless communications system includes measuring a first performance indicator and a second performance indicator for a reverse link associated with a subscriber station seeking access to a wireless communications system. A blocking threshold value is established based upon the measured second performance indicator and may be adjusted to allow more or less blocking based on any additional metrics that characterize the performance of the current subscriber stations. The decision to grant or deny access of the subscriber station to the wireless communications system is determined based on a comparison of the measured first performance indicator to the established blocking threshold value.

Abstract: The invention relates to an acoustic wave sensor formed of piezoelectric material. The sensor comprises a piezoelectric sensor plate spaced apart from an induced dynamic magnetic field, such as from an electromagnetic coil through which AC current flows. The dynamic magnetic field induces vibration in the sensor plate by fluctuating the aligned dipole moments of the piezoelectric material. The invention represents an improvement over conventional sensor methodologies in that no metallization of the sensor surface is required. The sensor may be used to detect biomolecular interactions between probe and target molecules.

Title: Progressive-power glasses lens and design process for same
Inventor: KITANI AKIRA
IPC: G02C7/02
Filed: 2000-04-12
Abstract: The present invention provides a progressive-power lens affording superior wear comfort, even where a shallow base curve is employed in order to make the lens lighter and thinner, which is desirable in the terms of weight and aesthetic design. In the case of a progressive-power lens for correcting hyperopia whose distance portion has a positive refractive power, such lens is designed by giving preference to minimizing transmission astigmatism at each point on the principal sight line of the distance portion, but not giving preference to making the astigmatism of the lens surface zero at each point on the principal sight line. On the other hand, in the case of a myopia corrective progressive-power lens for correcting myopia whose distance portion has a negative refractive power, such lens is designed by giving preference to minimizing transmission average refractive power error at each point on the principal sight line of the distance portion, but not to making the astigmatism of lens surface zero at each point on the principal sight line.

Inventor: KADY DARREN J
IPC: E05B71/00
Filed: 1998-10-26
Abstract: The operating control device (80) can be used on equipment such as hand tools, electronics or fuel pumps. An input devise (12) enables the input of user access codes and a readout panel monitors the equipment status. A control member is in communication with the input device (12), readout panel, power source (108), driver member and activation member to prevent operation of the equipment by requiring entry of a user nods. The control device (80) can include a programmable timer to communicate with the control member to enable the power to flow from the power source (108) to the driver member for a predetermined period of time. A clack can track time and activate and deactivate the timer based. The communication can be through electrical wires that can be encased in a solid material to make the control member and wires inaccessible. When used directly on a fuel pump, the control member prevents fuel from reaching the engine without the input of a proper user code. Alternatively, the control devise (80) can be a fuel line shutoff valve to prevent fuel from traveling along the line. A solenoid (206) can be used in the shutoff valve to prevent flow of fuel from the gas tank to the driver. A  locking device (208) for use on bicycles interacts with the axle (204) connecting the peddles.     An engagement disk (236) having multiple ports along its circumference, is unmoveably affixed to the axle. A locking bar activation member engages and disengages a locking bar (210) with the engagement disk (236) to prevent rotation of the axle (204).

Inventor: COLBORN JEFFREY A
IPC: H01M8/04
Filed: 2000-11-21
Abstract: A system and method is disclosed for preventing dendrite formation in a fuel cell, battery or metal recovery system. Typical metal/air fuel cell stacks comprise a plurality of cells electrically coupled together in a serial fashion. Electrolyte is typically pumped through the cells on a continuous basis using an input and output manifold device having a number of channels equal to the number of cells comprising the stack. This parallel connection causes the formation of metallic dendrites in the channels, which can short circuit the fuel cell stack or battery or metal-recovery apparatus. The system and method provides one or more dendrite elimination zones to prevent the formation of dendrites. The dendrite elimination zones are constructed within each cell or within each manifold to prevent the electrochemical reaction associated with dendrites from taking place. The dendrite elimination zones are characterized by the substantial lack of a metal negative electrode, such as zinc, in the volume of the zone, and the substantial presence of a cell positive electrode through the volume or adjacent to the volume.
