Abstract: A method and apparatus is provided for the overlaid operation of two or more wireless communication systems where one of the two systems is a small-scale or indoor system and the other is a large-scale or outdoor system. The indoor system monitors the operation of the outdoor system and detects which part of the available radio resources are temporarily not in use or interference-free in the outdoor system. The indoor system dynamically selects an unused outdoor channel for indoor operation. The indoor radio traffic is divided into TDD time slots with the slots being used for monitoring the existing radio communication on other outdoor channels so that fast changes according to changing traffic and interference conditions are possible. Synchronization, timing and phase control may be added to assist in the maintenance of an error-free communication network.

Abstract: A fast data transfer collection system using message authentication and contactless RF proximity card technology in non-contact storage and retrieval applications. The system is generally comprised of Host computers (application computer systems), Target radio frequency (RF) terminals, and a plurality of portable Tags ("smart" or "proximity" cards). A Host provides specific application functionality to a Tag holder, with a high degree of protection from fraudulent use. A Target provides control of the RF antenna and resolves collisions between multiple Tags in the RF field. A Tag provides reliable, high speed, and well authenticated secure exchanges of data/information with the Host resulting from the use of a custom ASIC design incorporating unique analog and digital circuits, nonvolatile memory, and state logic. Each Tag engages in a transaction with the Target in which a sequence of message exchanges allow data to be read(written) from(to) the Tag.

Commonly the process gas will be a Group VIII gas, preferably He, Ne, Kr or Xe, or a gas which comprises a hazard to the ambient environment or beings therein, such as a carbon oxide gas, a halocarbon gas, an acid-precursor gas, a biologically hazardous gas, or a radioactive gas.

Abstract: An x-ray focal plane array (XFPA) detector is fabricated by a laser micro-milling method under strict process control conditions. The detector has an array of phosphor pixels bonded together with a light reflective adhesive filling the grooves between adjacent pixels. The phosphor array is bonded on top of a visible detector array, either directly or via a light guiding structure, such that each phosphor pixel is aligned with a corresponding visible detector pixel. The phosphor array is fabricated by moving a phosphor substrate relative to a laser beam of predetermined intensity at a controlled, constant velocity along a predetermined path defining a set of grooves between adjacent pixels so that a predetermined laser flux per unit area is applied to the phosphor material, and repeating the movement for a plurality of passes of the laser beam until the grooves are ablated to a desired depth.

Abstract: The cutting tool for machining valve seats comprises a driving system, a machining head, a pilot, a depth gauge, and a system controller. The driving system provides rotational movement and vertical movement for the machining head which is controlled by the system controller. The machining head further comprises a pinion feed driving assembly and a universal cutting blade. The pinion feed driving assembly causes the cutting radius of the cutting tool to decrease as the machining head rotates. The pilot is attached to the bottom of the machining head to provide a means for centering the cutting tool. The depth gauge is disposed on the driving system and is electrically connected to the system controller. The depth gauge measures the distance between a valve seat and the cutting blade. The system controller includes memory and programming for controlling the operation of the cutting tool. An operator can input the parameters that define the geometry of the valve seat profile.

Abstract: An allergen particle detecting apparatus has a sample area through which environmental air is directed. A light beam is directed through the air sample so that portions of the beam will be scattered if any particles are present in the path of the beam. A beam blocking device on the opposite side of the air sample is arranged to block all light except light scattered in a predetermined angular range corresponding to a predetermined allergen particle size range. Light transmitted through the blocking device is detected by a light detector and an alarm output signal is produced if the detected amount of light is above a predetermined level.

Abstract: A golf club head has a perimeter formed by bending a tube into a desired perimeter shape, and securing a member over at least part of the loop to at least cover the loop opening and form the striking face. At least one plug of weighting material fills a portion of the tube at a predetermined location on the loop to form a weighted portion. Successive plugs of the weighting material and a lighter weight material may completely fill the tubular loop. Each plug is inserted while the material is in a flowable condition and the loop is held in a suitable orientation based on the location of the plug. The material is allowed to harden before adding the next plug.

Abstract: The input AGC and reference (REF) voltages are converted to currents and provided as differential inputs to a current amplifier. The current amplifier scales these currents proportional to absolute temperature. The translinear principle is used to realize the current amplifier and ensures linearity of the differential output currents. These currents are then converted to voltages by resistor elements. The result is applied to a simple differential pair that produces two AGC control currents that follow the hyperbolic tangent function. The two AGC control currents are equal when the AGC input is three-fourths the reference value. The overall gain response is well modeled by a second order function and is self-limiting at high gain values.

Abstract: A method for improving the radio cell illumination in a cellular mobile radio system provides that there are a number of neighboring cells adjoining each other and partially overlapping each other, wherein in the marginal region of each cell is arranged at least one fixed transmitter. In order to obtain optimized radio cell illumination, it is provided that the fixed transmitters of neighboring cells directly adjoining a cell transmit to this cell with the same channel group as the fixed transmitter of the cell to be supplied itself. In this way a mobile station located in the cell is supplied not only by one fixed transmitter, but also by the fixed transmitters of neighboring cells. Each fixed station is assigned several sector aerials which at least partially overlap in their transmitting range defined by sectors and which together sweep across at least a range of 360.degree..

Abstract: The system and method for provisioning resources in a network provides real time, parallel evaluation of the best path within the network using neural network principles. Elements of the network having a plurality of paths are assigned relative values according to a network user's requirements. Attributes may include factors such as reliability, cost, speed, distance, expandability, etc., and may be static or dynamic. Selection of a best path from the plurality of paths comprises application of fuzzy logic, using a threshold function to identify a best relative path value by providing an input to the function which is a combination of the attribute values of the elements within each path. The input to the function is the sum of weighted attribute values, where each attribute value is multiplied by a weight which is a relative value determined in accordance with the network user's priorities; the higher the priority, the greater the weight applied to that attribute.
