Title: Developmental learning machine and method
Inventor: WENG JUYANG
IPC: G06F15/18
Filed: 1998-10-07
Granted: 2009-06-30
Abstract: A machine and method capable of developing intelligent behavior from interaction with its environment directly using the machine's sensors and effectors. The method described is independent of the type of sensors and actuators, or the tasks to be executed, and, therefore, provides a general purpose learner that learns while performing. It senses the world, recalls what is learned, judges what to do and acts according to what it has learned. The machine enables the machine to learn directly from sensory input streams while interacting with the environment, including human teachers. The presented approach enables the system to self-organize its internal representation, and uses a systematic way to automatically build multi-level representation using the Markov random process model.  Reward and punishment are combined with sensor-based teaching to develop intelligent behavior.

Abstract: A postage metering system includes a plurality of meter printers operatively connected as part of a metering network and operating as client meter printers on the meter printer network. At least one postal security device (PSD) is coupled to at least one of the client meter printers (local client meter printer). The PSD includes unique identification the ability to store postal value and generate digital signatures. The client meter printers function as a postage metering network wherein a client meter printer other than the local client meter printer (remote client meter printer) requests evidence of postage payment from the PSD for concluding a postage metering transaction. The local client meter printer functions as a meter server and the remote client meter printer functions as a meter client on the postage metering network. The remote client meter printer initiates a postage metering transaction in the PSD by sending a request for evidence of postage payment to the local client meter printer. The local client meter printer sends the request for the evidence of postage payment to the PSD, receives transaction information from the PSD and sends the evidence of payment to the remote client meter printer for subsequent printing.

Abstract: A night light device provides a low level illumination using electro-luminescent lighting (30D) which is automatically fumed on when motion near the device is detected by the device and if ambient lighting level is low. When the ambient light level is above a specified level so that it is possible to see without artificial light, the device is inactive. A high intensity lighting feature (30F) allows the device to be used as a flashlight in emergencies since the device is fastened to a wall in such a way that it is easily and quickly removed. The front face (10A) of the device provides a downwardly directed surface (10A-1) for projecting light toward the floor, and sideways directed surfaces (10A-2, 10A-3) for projecting light to each side. Spherical Fresnel lenses (30B-1) enable the device to detect motion over a 180 degree azimuth. The case (10) of the device may have phosphorescent doping so as to provide a dim illumination even when the device is not energized.

Title: Moisture sensor for ore concentrates and other particulate materials
Inventor: ROSENBLUM EPHRAIM
IPC: G01N11/10
Filed: 1998-05-26
Granted: 2003-04-22
Abstract: The present invention is concerned with a moisture sensor for measuring the moisture content of particulate material like ore concentrates. The sensor comprises a body having one end to be buried within the bulk of the particulate material and the other end coupled to a force transducer. The force transducer itself is coupled to display means, so that when a conveyor  containing the ore concentrate is in operation, a signal is generated from t he force transducer and displayed as a result of the drag force exerted by the particulate material on the body. The moisture content may therefore be determined either by means of a calibration chart, or by the output of a calibration computer.

Abstract: An enhanced personal cooling garment has an inner layer and outer layer that define a confined space or bladder therebetween for containing liquid water. The inner and outer layer are thin materials that are impermeable to both air and liquid water yet permeable to water vapour. The garment is worn in a manner such that the innermost layer is in direct contact with the wearer's skin. The liquid water between the layers diffuses as vapour through the outer layer; it removes latent heat required for evaporation hence provides cooling to the human body. As both layers of the garment are permeable to water vapour, sweat produced by the wearer can diffuse through the innermost layer, where it will then condense into liquid. When worn beneath an air-cooling garment that distributes cool; dry air over the body, the rate of evaporation increases, resulting in even greater enhancement of cooling of the wearer.

Title: Motion analysis system
Inventor: FYFE KENNETH R
IPC: G01P7/00
Filed: 2000-06-28
Granted: 2011-02-22
Abstract: A device comprised of at least a pair of accelerometers and a tilt sensor mounted in fixed relation to a datum plane defining surface (sole of a shoe) may be used for extracting kinematic variables including linear and rotational acceleration, velocity and position.  These variables may be resolved into a selected direction thereby permitting both relative and absolute kinematic quantities to be determined. The acceleration is determined using a small cluster of two mutually perpendicular accelerometers mounted on a shoe. Angular orientation of the foot may be determined by double integration of the foot's angular acceleration (which requires a third accelerometer substantially parallel to one of the two orthogonal accelerometers). The two orthogonal accelerations are then resolved into a net horizontal acceleration or other selected direction which may be integrated to find the foot velocity in the selected direction. The average of the foot velocity corresponds to the subject's gait speed.

Title: Portable environmental containment system
Inventor: STARHEIM SCOT A
IPC: E21B21/01
Filed: 2000-08-30
Granted: 2003-11-18
Abstract: A temporary berm or bin system, easily transported, erected without tools, and easily dismantled. A set of panels or planks is joined with sliding clips to form a bin having vertical or near vertical sides. The bin is lined with an impervious sheet of geocloth to form a containment bean for use in controlling the dispersal of hazardous material spilled from storage or work facilities. Spring loaded clamps hold the geocloth securely to the uppermost plank without nailing, sewing, or other labor consuming and/or tear prone methods. The bean is particularly suited to protect oil well drilling sites in environmentally sensitive environments such as arctic tundra. No excavation or other disturbance of the soil is required to erect the protective bean. The bean is secured to the ground by spiking through triangular support gussets. In the arctic, securing may be accomplished by freezing ice or mud as an "ice mortar" over the gusset feet and along the lower edge of the planking. The berm system may be transported by ordinary truck, specially adapted transport/laying truck, or on a portable drilling platform.
