Abstract: A keypad having a virtual floating image that appears to a user to be in a plane other than the apparent plane of the keypad surface. More particularly, the indicia on the keypad appear to float above or below the surface of the device. The keypad can be, for example, the keypad on a cell phone. For such an application there would be more than one array of indicia present on the keypad. For example, there might be ten arrays of indicia, which provide the numerals from 0 to 9 and two more arrays to provide virtual images of the * and # keys. In some embodiments, the keypad is integrated with an illumination source that light up the indicia. The present disclosure also provides a method of manufacturing a key pad with a virtual floating image.

The apparatus includes a first patterned roll; a second pattered roll; and a means for rotating the first and second patterned rolls such that their patterns are transferred to opposite sides of the web while it is in continuous motion. During this process, their patterns are maintained in continuous registration to within at least 100 microns, and preferably at least 20 microns.

Abstract: An arrangement in a node in an optical communication network has one or more terminals 220 and/or 222 configured to provide local access to the network through the node, and an all-optical routing arrangement 202-204-206-208 configured to route optical signals among optical pathways extending from the node. The optical pathways include inter-node optical pathways (for example, pathways N and/or W) configured to carry optical signals into and out of the node to respective other elements in the network, as well as intra-node optical pathways (for example, pathway E) dedicated to carry optical signals between the routing arrangement and respective terminals so as to provide the local access to the network through the node. Placing the terminals on optical pathways allows redundancy of the terminals to avoid node isolation if a terminal fails, yet is more economical than conventional arrangements requiring a terminal for each pathway into the node.

Abstract: Web tension in web material passing through a web transport system is determined in real time using position sensors coupled to driven rollers that define a beginning and an end of a tension zone. The position sensors on the rollers provide information related to the amount of strained web material that has been added and subtracted from the web material present in the tension zone. The amount of web material added to, subtracted from and present in the tension zone in a sample time period is then converted to an unstrained amount of web material that when combined provides an estimate for the present amount of unstrained web material present in the tension zone. Because the length of the tension zone is both fixed and known, the tension in the web material is determined from the present amount of unstrained web material in the tension zone.

Abstract: An automated material handling system utilizing one or more train-type guided vehicles moving along a rail with each train including a locomotive pulling a plurality of trolleys. Each trolley includes a tiltable tray, an onboard CPU, and onboard sensors for sensing information with respect to the product being carried by the tray. The sensed information is transmitted to the CPU of the trolley where it is stored and also transmitted to a CPU in the locomotive. The locomotive CPU is in radio frequency contact with an off-track dispatch computer controlling the overall operation of the material handling system. The CPU of each trolley is also in infrared communication with local CPU's positioned at unloading stations so that the CPU on each car may receive information by infrared transmission from local CPU's, information generated onboard by the onboard sensors, and command information from the locomotive CPU.

Abstract: An automated material handling system including one or more train assemblies moving along a rail with each train assembly including a locomotive pulling a plurality of trolley cars. The locomotive includes a front truck adapted for movement along the rail; a rear truck adapted for movement along the rail in spaced trailing relation to the front truck; a body structure mounted on and extending between the front and rear trucks; a tractor positioned between the front and rear trucks, disassociated from the body structure, and including a motor and a traction drive wheel driven by the motor and adapted to drivingly engage the rail; and a link pivotally interconnecting the tractor and the rear truck. The body structure defines a central downwardly opening compartment between the front and rear trucks and the tractor is positioned in the compartment. The tractor is thus free to essentially independently perform the pulling function for the train without concern for the carrying function of the locomotive.

Abstract: A total hip joint prosthesis with primary fixation includes a partially threaded elongated pin for insertion into the femoral body to provide primary support for the prosthesis. Attachable thereto is a proximal body whose shape simulates the proximal medial region on the femur and provides a neck for the attachment of a head to contact the acetabulum. The components are constructed to allow for relative rotational adjustment between the body and the pin, thus providing for various alignments and size combinations to offer a custom fit in view of the individual patient's needs. A tapered bore through the body member receives a threaded mounting post on the pin while a nut having a tapered bottom portion seats within the bore to secure the components in a fixed manner.

Abstract: A grinder for removing a predetermined amount of rubber at a predetermined angle from a raised or recessed area on the sidewall of an inflated tire as the tire rotates. A pair of spaced sensors engage the sidewall area of the tire at predetermined radial spaced locations on opposite sides of the area to be worked. The sensors generate a pair of electrical signals in relationship to the profiles of the sidewall areas engaged thereby. The signals are fed to a microprocessor which calculates the average angle of the raised or recessed area by the difference between the outputs from the two sensors along with the known spacing therebetween and generates a third signal. This third signal is supplied to a servo mechanism which automatically adjusts the grind angle of the grinding wheel to match the average angle of the area to be ground.
