Abstract: The invention concerns Liquid Crystal Displays (LCD), in which Polymer-Dispersed Liquid Crystal (PDLC) is used. PDLC does not require the use of polarizing filters and half-reflective mirrors, as do some other LCDs. Eliminating the polarizing filters and mirrors eliminates the light attenuation which the filters and mirrors cause. Thus, less light input is required, which increases battery life in devices which are battery-powered. The invention provides a color display by applying color filters to each pixel, and by edge-illuminating the PDLC.

Abstract: A catheter system for use in a body of a patient is disclosed. The catheter system includes a guide catheter having a distal guide orifice, a proximal guide orifice, and a guide lumen extending therebetween. The catheter system further includes an original catheter positionable within the guide lumen of the guide catheter, wherein the original catheter has an original lumen and an original distal orifice. In addition, the catheter system includes a replacement catheter positionable within the guide lumen of the guide catheter, wherein the replacement catheter has a replacement lumen and a replacement distal orifice. The catheter system also includes a closure member securable to the guide catheter so as to cover the proximal guide orifice. The original distal orifice is positioned on an original distal segment of the original catheter which extends out of the distal guide orifice of the guide catheter when the original catheter is positioned within the guide lumen of the guide catheter.

Abstract: A fan assembly for a work machine includes a fan housing which has a fan guard and a fan shroud defined therein. The fan housing includes a rotationally molded, hollow exterior shell structure. The exterior shell structure is filled with a filler material so as to enhance the structural rigidity and stiffness of the fan housing. The fan assembly of the present invention utilizes fewer components relative to fan assemblies which have heretofore been designed thereby decreasing costs and assembly time associated with the work machine.

Abstract: Methods and apparatuses are provided to check the order, continuity and correctness for the data segments in a test message received via a network by a terminal. The test message contains a non-repeating data pattern in which any small portion of a known length is sufficient to generate the remainder of the message. To check the order and continuity of a pair of data segments, the receiving terminal needs to check only the beginning portion of the trailing segment against the ending portion of the preceding segment, thus improving the efficiency.

Abstract: A recoil and slack adjustment mechanism for tensioning an endless track chain of an undercarriage assembly of a work machine includes a ram assembly and an accumulator assembly. The ram assembly includes a ram housing having a ram chamber defined therein. A recoil ram is movably housed within the ram chamber. The recoil ram has a ram subchamber defined therein. The tensioning ram is movably housed within the ram subchamber and is coupled to a front idler roller of the undercarriage assembly. A check valve is disposed between the ram chamber and the ram subchamber such that fluid pressure from the accumulator assembly is selectively exerted on the tensioning ram thereby urging the front idler roller so as to bias the track chain of the undercarriage assembly. The recoil and slack adjustment assembly provides continuous, constant tensioning of the track chain, and does not require the use of live hydraulics.

Abstract: A braking apparatus includes a brake cylinder having a first opening and a second opening defined therein. The braking apparatus also includes a movable member located within the brake cylinder which has a channel defined therein. The braking apparatus further includes a brake chamber in fluid communication with the brake cylinder. The brake chamber has a brake member located therein. The movable member is moved to a position which allows fluid communication between the first and second opening through the channel thus creating a subsequent pressure drop in the system. The pressure drop causes a hydrostatic transmission in fluid communication with the brake apparatus to be neutralized by a responsive displacement of a pump and motor which reduces the travel speed of a vehicle. Additionally, the movement of the movable member causes a brake member to be forced against a moving object.
