Abstract: The dielectric-based coating above the metallic layer comprises a sequence of layers deposited in the order: (a) layer(s) of materials of refractive index ni-2 above 2.2; (b) layer(s) of materials of refractive index ni-1 at least 0.3 below that of the last layer(s) ni; and (c) last layer(s) material of refractive index ni more or less equal to ni-2. The metallic layer with infrared reflecting properties is based on silver, is preferably in direct contact with the subjacent dielectric material-based coating, has a geometrical thickness of 7-20, especially 9-5 nm, for low emissivity, and 20-25 nm for solar protecting properties. A protective metal layer of thickness not greater than 2 nm and selected from Nb, Ti, Cr or nickel, or an alloy of at least two of these metals, especially Nb/Cr or Ni/Cr, can be located immediately above and in contact with the metallic layer with infrared reflecting properties. The dielectric coating below the IR-reflecting metal layer comprises at least two layers, especially two metal oxide layers or a metal nitride layer, e.g. AlN and S3N4, and a metal oxide layer, e.g. ZnO, SnO2 and TiO2, preferably with direct contact between the dielectric coating and the IR-reflecting metallic layer. The last layer is selected from one of the following: Si3N4, Si3N4:Al, AlN, SnO2, SnZnOx and carbides such as SiC, TiC, CrC and TaC. Independent claims are given for: (A) Low emissivity or solar protection multiple glazing unit; and (B) Low emissivity double glazing unit.

Granted: 2007-05-01
Abstract: A support structure includes first and second support members which are interlocked with a body. The second support member is placed in a die such that a hole of the second support member is located at a predetermined position and the body is placed on the second support member. The first support member is placed on the body such that apertures of the support members and an opening of the body are aligned. A shaping pin is then advanced toward the first support member in alignment with the predetermined position so that a shoulder of the shaping pin extends into the first support member. The shaping pin continues to advance through the first support member until a portion of the body extends past a surface of the second support member, thereby joining the first and second support members and the body together.

Title: Low-voltage transconductance amplifier/filters
Inventor: CHERRY JAMES A
IPC: H03F3/45
Filed: 2000-02-09
Granted: 2003-07-29
Abstract: Wireless communications devices must handle a wide range of useful signal levels and must also cope with large interfering signals of nearby frequencies. They often use transconductance amplifiers/filters as building blocks as such amplifier/filters exhibit good characteristics of both amplification and filtering.    The transconductance cells described make use of feedbacks which involve no signal conversions. As the result, the cells have high linearity and yet can operate at low voltage.

Title: Automated system and method for identifying and measuring packages transported through a laser scanning tunnel
Inventor: GHOSH SANKAR
IPC: G06V30/224
Filed: 1999-03-24
Granted: 2008-10-28
Abstract: A fully automated package identification and measuring system, in which omni - directional laser scanning systems (10, 101, 107) are used to read bar codes on packages entering the tunnel, while a package dimensioning subsystem (600) is used to capture information about the package prior to entry into the tunnel. Mathematical models are created on a real-time basis for the geometry of the package and the position of the laser scanning beam used to read the bar code thereon. The mathematical models are analyzed to determine if collected and queued package identification data is spatially and/or temporally correlated with package measurement data using vector-based ray-tracing methods, homogeneous transformations, and object-oriented decision logic so as to enable simultaneous tracking of multiple packages being transported through the scanning tunnel.

Granted: 2008-07-29
Abstract: An apparatus and method of maximizing the efficiency of an induction motor is claimed. Three phase AC power is supplied to energize the motor. A DC voltage and a DC current are measured and used to determine an estimated phase voltage. An actual torque producing current is determined based on the DC voltage, DC current and the estimated phase voltage. An estimating torque producing current value is determined and compared with the actual torque producing current value. An error term representing the difference between the actual and estimated torque producing current values is determined.  The estimated phase voltage value is changed based on the error term. The three phase AC power supplied to the motor is adjusted based on the estimated phase voltage.

Abstract: The invention is an encapsulated active agent comprising an active agent encapsulated in a crystallizable or thermoplastic polymer wherein the particle size of the encapsulated active agent is 3,000 microns or less wherein the active agent is not significantly extractable from the particles under ambient conditions. In another embodiment the invention is a process for preparing an encapsulated agent which comprises: a) contacting an active agent with a crystallizable or thermoplastic polymer wherein the polymer is molten and the active agent is not volatile under the contacting conditions; b) forming particles of 300 0 microns or less; and c) exposing the particles to conditions such that the portion of the particle at and near the surface undergoes rapi d solidification. The encapsulated active agents of the invention do not require washing in order for them to be stable in curable composition s. These encapsulated active agents can be designed to release the active agent at a desired temperature. The encapsulated agents of the invention demonstrate excellent stability at ambient temperatures and exhibit relatively rapid reactivity upon release of the active agent. Furthermore, the presence of the encapsulating agent does not result in deterioration of adhesive or elastomer properties of a cured composition after preparation.

Abstract: Truck cabs are enclosures for housing the drive of the vehicle to help protect him/her from the elements and from injury in case of an accident. This invention, the round cab a design, as in a seen in a plan view, helps to protect the driver in case of accidents in a superior way. In cases of head on collisions vehicles will deflect off of the cab easier than in the conventional square front cab. In cases of rollovers the cab will roll or slide easier with fewer injuries to the driver. The round cab gives the driver a much better view of his surroundings, as there are not any blind corners. With the sleeper located in the middle of the cab, the driver will be less likely to injury if the vehicle is struck while the driver is stopped and resting. The doors to the cab open inward in case of an accident so that the driver may escape easier. To service the motor or change the front tires the cab lifts forward on hydraulic cylinders attached to the frame and cab. Access to instruments and accessories are all from inside the cab of the truck so that replacing parts or making repairs is a lot easier.
