Title: Screening assay methods and systems using target pooling
Inventor: WADA H GARRETT
IPC: C12Q1/42
Filed: 2001-04-10
Abstract: Methods, devices and systems for increasing the throughput of screening assays by pooling multiple target systems, which allow a library of different materials, e.g., test compounds, to be screened against the pooled targets to determine whether any of the materials affect one or more of the target systems. In preferred aspects, functioning of individual target systems is identified by differences in physical, chemical and/or optical properties particular to the target system in a target pool.

Abstract: The filter integrator (1) is used in an enslavement loop of a Sigma-Delta modulator which also comprises an analog-digital converter (2) and a digital-analog converter (3) in the same loop. The filter integrator comprises in particular two resonant cells 6p(1), 6p(4) in the form of parallel LC circuits, a series circuit with alternating amplifiers 12(1), 12(2), 12(3) and filters 11(2), 11(3), a fourth amplifier (12(4) connected to the output, a generator 5s, and a load (7). Each filter 11(2), 11(3) contains three sections, and each section contains two resonant devices, one series and the other parallel. The resonant cells 6p(1), 6p(4) are with low overvoltage and designed to minimize the effect of spectrum folding brought in by the analog-digital converter (2). The functioning of the modulator with closed loop is stable within the following margins +/- 20 degrees in phase, and +/- 3 dB in amplitude.  The resonant device comprises a resonator and a resistor, and the transfer function becomes dominant in one or more of the frequency bands. The resonant device is with a phase delay when the function of resistance is dominant in the frequency bands symmetric with respect to the resonant frequency. The resonant device is with a phase advance when the function of resistance is dominant in a frequency band comprising the resonant frequency. The filter is of a higher order, and the resonant devices are assembled in a cascade, in a ladder, or in a balanced bridge. The elements of components are implemented in a piezoelectric substrate, or in the interior of a ceramic case. The resonators are ceramic acoustic wave (SAW), bulk acoustic wave (BAW) or variants such as fundamental bulk acoustic resonator (FBAR), high order bulk acoustic resonator (HBAR) or thin film resonator (TFR), dielectric, or superconductor. The enslavement loop comprises the filter as claimed, and the latent number is strictly greater than 1. The Sigma-Delta pass-band modulator consists of the enslavement loop and comprises an analog-digital converter in the direct route and a digital-analog converter in the return route of the loop. One or more, or all of the elements of components are implemented in a semiconductor, and the filter is implemented in a piezoelectric substrate related to the semiconductor, or in the interior of a ceramic case of the modulator.

Abstract: An adjustable shock absorber is provided that includes a body defining a cavity. A member such as a piston is disposed in the body and at least partially separates the cavity in two first and second fluid chambers. A port extends through the piston and fluidly connects the first and second chambers during damping.  A deflection disc, typically several, are arranged adjacent to the piston and one of the chambers to at least partially obstruct the port. A flange member such as a washer is arranged in proximity to the deflection disc with the deflection disc arranged between the washer and the piston. The deflection disc bends about the washer, which acts as a fulcrum, to unobstruct the port. The washer has a first portion with a first radial width defining a first rate of damping and a second portion with a second radial width different than the first radial width defining a second rate of damping different than the first rate of damping. The deflection disc bends about the portion of the radial width that is in alignment with the port. Preferably, the washer is oval shaped. An adjustment member such as a knob selectively rotates the washer relative to the deflection disc between the first and second radial widths.

Title: Computer mouse
Inventor: MOLOO IMITIAZ
IPC: G06F3/0354
Filed: 2003-05-14
Abstract: The present invention provides a computer mouse adapted for use by children wherein the mouse has a housing which is ergonomically designed for use by an operator having small hands. Enclosed within the housing is an X-Y generator which enables the determination of relative movement of the housing on a surface, wherein this information is translated into a movement of the "cursor" on the display device of the computer system to which the computer mouse is interconnected. Further interconnected with the housing are first and second buttons common to a typical computer mouse, wherein these buttons enable the activation of one or more responses from the computing device upon the depression of these buttons commonly referred to as "clicking". The first and second button s are designed in a manner that they extend beyond the perimeter of the housing. In this manner the force to be exerted by a child in order to depress one of these buttons is reduced due to the lever arm that is associated therewith, when compared to the required activation force of a smaller button which would be associated with a typical mouse that has been reduced in size.  In addition, by the extension of these buttons the identification thereof by a child is simplier and therefore operation of the buttons can be more convenient.

Abstract: The invention relates to a guiding device for metal sheet printing machines (10) and metal sheet painting machines, which have at least two printing cylinders (11; 12) and a transfer drum (17) situated therebetween. The guiding device is arranged on said transfer drum (17) and, to be precise, is located close to the imaginary cylindrical outer surface (21) of the transfer drum (17). The guiding device comprises at least one guiding element (31) with an outwardly turned bearing surface (32) for supporting the rear edge (33) of the metal sheets (30). The guiding element (31) is pivotally mounted by means of a swivel bearing (35) whose pivotal axis is parallel to the axis (18) of the transfer drum (17). The guiding element (31) is coupled to a pivot drive by means of which its bearing surface (32) can be adjusted to different pivoting angles (.szlig.) with regard to the tangent (36) to the imaginary cylindrical outer surface (21) of the transfer drum (17). This pivoting angle (.szlig.) is larger at the rotating position of the transfer drum (17) at which the rear edge (33) of the metal sheets (30) rest against the guiding element (31), and is smaller at the rotating position at which the rear edge (33) of the metal sheets (30) leave the guiding element (31).

Abstract: Abrasive grinding wheels having an irregular (i.e., gapped) perimeter shape and/or holes extending therethrough permit one to view the surface of a workpiece being ground in conventional surface finishing, snagging and/or weld blending operations. The grinding wheels may each include one or more gaps disposed in spaced relation about the otherwise circular perimeter of the wheel. Holes also may be provided in addition to, or in lieu of, the gaps, and similarly spaced equidistantly about the wheel. The gaps and/or holes may be configured in many diverse shapes. Gap and hole positions may be selected so as to retain the balance of the wheel. Advantageously, when the wheels are rotated about their axes, one is able to monitor the condition of the surface of the workpiece as it is being abraded, without removing the grinding wheel from the surface.

Title: Soccer (or association football) goalkeeping game
Inventor: NELSON JEFFERY A
IPC: A63B69/00
Filed: 2003-06-03
Abstract: A soccer (or association football) goalkeeping game involves two players playing against each other on a playing field having a soccer goal at two opposite ends and demarcated with respective offside zones. The players have as objectives (t) offensively to move a play ball into the defender's goal and (ii) defensively to save attempts on goal and/or acquire ball possession in order to switch around and commence offensively. The rules of play can limit time-of possession to a time-limit, such as five seconds, so that ball possession in excess of the time-limit results in a turnover. Any unstopped scores from shots taken after the applicable time-limit are not counted. Another rule of play assesses any player who crosses into the offside zone of the opponent with a penalty-shot violation. Penalty shots are postponed until after a play period runs out of time so not to interrupt play.
