Abstract: Flexible link drive apparatus having a housing (100) rotationally supporting an eccentric input shaft (116) and an output shaft (118). An eccentric roller assembly (216) is coupled to the eccentric input shaft, and the eccentric roller assembly comprising at least one input roller (238, 240). Additionally, a clutch member (260) is coupled to the output shaft (118). The present disclosure further relates to a flexible connection member (282) that has a fixed end coupled to the housing through a flexible connection member anchor, and a free end coupled to the housing through a biasing member (268). The input roller (238, 240) intermittently contacts the flexible connection member and rotates the clutch member and the output shaft. The coupling of the free end of the flexible connection member to the housing by the biasing member causes a greater angle of travel for the clutch member and produces a greater output shaft rotation. <IMG>

Abstract: A method and an assembly is disclosed for sorting rolls of paper and paperboard web for shipment into a desired sequence based on customer orders, in which method and assembly a roll to be sortedis imported to an infeed conveyor (2), and from at least two first conveyors (3, 4, 5) is selected a suitable conveyor onto which the roll is transferred. Subsequently, the roll is transferred onto the selected conveyor so that its leading end remains at the receiving end of said selected conveyor, and the rolls are transferred onto the first conveyors (3, 4, 5) in a similar fashion so that the rolls thus placed onto the conveyors remain in a close disposition to each other so as to form a group of end-to-end abutting rolls until at least one of the first conveyors contains a roll group forming a unit load for an upender lift. Next, the rolls are transferred onto a second conveyor (6, 7, 8 or 9), and finally the rolls are removed from the system onto an outfeed conveyor (9) as roll groups forming a unit load for an upender lift so that the roll groups are taken off from the sequence of rolls resting on the conveyor being unloaded at the interface between the conveyor (6, 7, 8) being unloaded and the successive unloading conveyor (10).

Title: Interactive weather advisory system
Inventor: ROOT STEVEN A
IPC: H04H20/00
Filed: 2001-07-20
Granted: 2011-09-20
Abstract: A broadcast network for selectively transmitting individualized weather outputsignals to remote communicator devices. The broadcast network is comprised of a userinput database, a communicator location database, a weather information database, a weather analysis unit and a communication network. The user input database contains user-defined parameters and each of the user-defined parameters includes a spatial range identifier and a user profile. The user profile in each of the user-defined parameters utilizes a user identifier code and identifies a communicator device associated with a particular user. The communicator location database contains real-time data indicative of the spatial locations of the communicator devices. The weather information database contains real-time weather data for the spatial locations contained in the communicator location database. The weather analysis unit repeatedly compares the spatial range identifier included in the user-defined parameters and the spatial location of each communicator device contained in the communicator location database with the real-time weather data and generates an individualized weather output signal including weather information within the spatial range identified by the spatial range identifier for each user-defined parameter. The communication network transmits each individualized weather output signal to the particular communicator identified by the user identifier code defined in the user profile included in the user-defined parameter corresponding to the real-time weather data whereby a user can receive weather information in real-time specific to the user's immediate location regardless of whether or not the user's location remains fixed or dynamic throughout time.

Granted: 2007-09-11
Abstract: A method and apparatus for adapting an acoustic touchscreen controller to the operating frequency requirements of a specific touchscreen are provided. The adaptive controller can either utilizw look-up tables to achieve the desired output frequency or the it can use a multi-step process in which it first determines the frequency requirements of the touchscreen, and then adjusts the burst frequency characteristics, the receiver circuit center frequency, or both in accordance with the touchscreen requirements. In one embodiment, the adaptive controller compensates for global frequency mismatch errors. In this embodiment a digital multiplier is used to modify the output of a crystal reference oscillator. The reference oscillator output is used to control the frequency of the signal from the receiving transducers and/or to generate the desired frequency of the tone burst sent to the transmitting transducers. In another embodiment that is intended to compensate for both global and local frequency variations, the adaptive controller uses a digital signal processor.  The digital signal processor, based on correction values contained in memory, defines a specific center frequency which preferably varies according to the signal delay, thus taking into account variations caused by localized variations in the acoustic wave reflective array. In yet another embodiment, a non-crystal local oscillator is used to provide the reference signal in the adaptive controller. The use of such an oscillator allows the controller to be miniaturized to a sufficient extend that it can be mounted directly to a touchscreen substrate. A feedback loop is used to compensate for oscillator drift. A discriminator circuit determines the degree of deviation from the desired frequency. The output from the discriminator is used to adjust the frequency of the local oscillator such that it tracks the frequency of the touchscreen.
