Abstract: A novelty soap bar is disclosed. The bar comprises an attractor module within a soap body made of substantially translucent or transparent soap, surrounding the attractor module. The attractor module comprises a water impermeable shell; an electronic, actuatable circuit within the shell adapted to cause emission of at least one of a visible and an audible signal, perceptible through the soap body; and a battery within the shell for providing energy to the circuit to cause emission of the visible signal. The module further comprises a light sensitive switch, mounted within said soap body to sense light exterior to said soap body, and interconnected with the circuit and the battery, to inhibit flow of current from the battery in the absence of light; and a motion sensitive switch interconnected with the circuit, to activate the circuit in response to sensing motion of the soap bar. The attractor module may be arranged to produce an animated sequence visible through the soap bar. The animated sequence may be formed using LEDs, LCDs, reflective sheets, or an electromechanical carousel.

Granted: 2006-06-13
Abstract: In a method for providing a secure communication between two devices, a first device generates a random key (Ci) and transfers this key to a second device in a first message encrypted using a plublic key.  The second device decrypts the first encrypted message by means of a corresponding secret key to obtain the random key (Ci) and this random key is used to encrypt and decrypt all transmissions between these devices. In a decoder for a pay TV system, comprising a conditional access module and a smart card, this method is applied to provide a secure communication between the control access module and the smart card and/or between the decoder and the conditional access module.

Abstract: A weapons training range provides a simulated weapons use scenario including return fire. A microprocessor select branches from a multi-branch program and causes an image projector to project subscenarios on a display screen visible to a participant. In response to the subscenarios, the participant fires at projected threats. Return fire simulators positioned behind the display screen return fire toward the participant. Obstructions are placed in the weapons range to provide cover for the participant. A video camera and X-Y position sensor identify the X-Y location of the participant and try to detect exposed portions of the participant. Based upon the identified X-Y location and any detected exposed portions the microprocessor aims the return fire simulators to provide simulated return fire. To simulate real world aiming, the microprocessor induces time-based and response-based aiming errors. Additionally, the microprocessor may aim the return fire simulators at objects in the participation zone to produce deflected fire that may also strike the participant.

IPC: E21B23/01
Filed: 1999-03-05
Granted: 2002-02-26
Abstract: A tool is provided for preventing the rotation of a downhole tool or rotary pump stator, the tool comprising a tubular housing and a jaw which pivots radially outwardly from the tool upon tool rotation to engage the casing wall for arresting tool rotation and providing significant stabilization of a rotary pump. In doing so, the tool housing moves oppositely to rest against the casing opposite the jaw. The tool housing and the downhole tool are thereby restrained and stabilized by the casing wall. The tool's jaw is released and is stowed adjacent the housing by opposite tool rotation. Preferably the profile of the jaw allows it to stow closely against the housing for presenting minimal obstruction. More preferably, the jaw is formed independent of the housing and the bore supports differential pressure so that the tool can be installed above a rotary pump or as a part of an extended tailpiece.

Title: Rotary steerable well drilling system utilizing sliding sleeve
Inventor: DOREL ALAIN P
IPC: E21B47/022
Filed: 1999-12-07
Granted: 2007-09-25
Abstract: An actively controlled rotary steerable drilling system for directional drilling of wells, the system having a rotary drive component rotatable within a tubular sliding tool collar that incorporates elastic anti-rotation members to maintain a coupled relation with the borehole wall during drilling. An offsetting mandrel is supported within the tool collar by a knuckle joint for pivotal movement and for rotation relative to the tool collar and has a lower end extending from the tool collar and supporting a drill bit. To achieve controlled steering of the rotating drill bit, orientation of the tool collar is sensed and the offsetting mandrel is maintained geostationary and selectively axially inclined relative to the tool collar by orienting it about the knuckle joint. An alternator and a hydraulic pump, located within the tool collar, are driven by relative rotation of the rotary drive component with the tool collar to produce electric power and hydraulic pressure for the electronics package of the tool and for actuation of hydraulic system components. Hydraulic cylinder and piston assemblies, actuated by tool position signal responsive solenoid valves, control the angular position of the offsetting mandrel with respect to the tool collar. The hydraulic pistons are servo-controlled responsive to signal input from tool position sensing systems such as magnetometers and accelerometers which provide real-time position signals to the hydraulic control system.

Title: Spray application of an additive composition to sheet materials
Inventor: NIELSEN KENNETH ANDREW
IPC: D06M23/06
Filed: 1998-10-09
Granted: 2004-07-13
Abstract: The present invention is directed to methods for the spray application of additive compositions containing additive materials in the manufacture of sheet material products, such as paper products, textile products, and flexible sheet products by using compressed fluids, such as carbon dioxide and ethane as a spraying medium. Additive composition s with high viscosity and which are substantially free of water and/or volatile solvent can be applied to sheet materials. Water-home additive compositions with reduced water content can also be applied to sheet materials. One preferred spray method uses a decompressive spray of the compressed fluid which produces a uniform spray pattern and a narrow droplet size distribution that can improve application efficiency and quality when additive compositions are applied during the spraying step to rapidly conveyed sheet materials.
