Abstract: A trolley for moving heavy objects such as wire coils from a machine to a container at a packaging table is provided. The trolley includes spring-loaded spaced arms movably mounted for vertical height adjustment so that the arms are just below the coil when it is on the machine and rotational movement to separate the spaced arms with the spaced arms retaining the heavy object during movement of the trolley apparatus, and locking arms engaging the spaced arms during movement of the trolley apparatus to prevent separation thereof. The spring-loaded arms permit the heavy object to be manually pushed downward therebetween, thereby forcing the arms apart enabling the object to fall from the trolley into a container on a packaging table. The table includes a platform for supporting the container, a motor for raising/lowering the platform, and a mechanism for retaining the container and aiding its alignment with the coil.

Abstract: Apparatus for producing heat-shrinkable packaging with an integrated hand-hold with a circuitous path extending from an input loading/unloading zone, a section where the open portion of a heat-shrinkable bag is sealed shut and creating a container in which an object is enclosed, a section in which heat is applied directly to exposed areas of the plastic film of the package for sealing the package, and a section of path enabling the package to cool; trolley apparatus for supporting the package and engaging the circuitous path for movement of the package along the circuitous path; and protrusions positioned along the circuitous path for propelling the device along the designated track route.

Abstract: A coated abrasive article (1) comprises a backing (3) having an abrasive coating (5) on one side, an attachment layer (7) on the other side of the backing, and a line of weakness (9) that does not penetrate the front face of the abrasive coating (5). The line of weakness, which may be formed using a laser beam, comprises a through-cut (11) in the attachment layer (7) and perforations (13) in the backing (3), and permits one part of the abrasive article (1) to be separated from another part. Alternatively, the abrasive article can be used in its original form.

Abstract: Disclosed herein are devices for brewing coffee in conjunction with an electro-conductivity sensor. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.

Abstract: An apparatus and method for sorting plant material based on the presence or absence of a visual marker on the plant material. The visible marker may be a visible genetic color marker in the corn seed which is used in double haploid breeding. The absence or presence of the visible marker identifies correctly pollinated seeds as well as putative haploid seeds.

Abstract: A method of using an injection mold assembly to fabricate a bulkhead fitting. The method includes using a core plate, aperture plate and a pair of slide blocks to form the mold assembly which contains the mold cavity. The aperture plate, which has an opening through the plate, is positioned within the assembly such that the fitting, which is molded within the mold cavity, does not contain a parting line across the sealing surface and o-ring groove of the fitting.

Abstract: Methods and materials involved in detecting fungi in human samples are provided herein.

Abstract: An audience response system is provided. In various implementations, the response system includes a base station, handheld units, and a wireless network. The response system may have a prompted mode and an unprompted mode of operation. In the prompted mode of operation, the base station transmits questions to the handheld units over the wireless network. The questions are displayed to users on their handheld units. The users respond to the question, and their responses are transmitted to the base station via the wireless network. In the unprompted mode, answer templates are transmitted and displayed to the users, with the actual questions being conveyed in some other manner, such as verbally or by written handout.

Abstract: A wireless classroom response system includes multiple wireless networks, each serving a different classroom. Each network has a computer located proximate to the classroom that the wireless network serves. The computer executes a communications server and an application program, wherein the application program facilitates classroom activities. The system also includes a wireless access point located proximate to the classroom. The wireless access point is communicatively linked to the computer. The system also has a plurality of handheld units. Each handheld unit displays, to a user, a list of the networks, and receives a user input indicating which one of the wireless networks the handheld unit should connect. The handheld unit connects to the chosen wireless network, thereby becoming a node in the wireless network. It also transmits data to the application program via the wireless access point and the communications server.

Abstract: A wireless classroom response system wireless network is located proximate to a classroom, a base station that coordinates the activities of the wireless network, and a plurality of handheld units. Each handheld unit is associated with an attendee of a class (either on a long-term or “owned basis, or on an ad-hoc or “shared” basis). Each handheld unit performs a discovery process that includes the steps of randomly choosing a wireless channel, attempting to discover the presence of the wireless network on the channel, and repeating these two steps if no wireless network is discovered.

Abstract: Abrasive articles have an adhesive layer in contact with a liner having protrusions that contact the adhesive layer.

Abstract: A winding accumulator system for controlling the storage of filamentary material between a source of such material and a winding receptacle, utilizing: a plurality of serially interconnected accumulator units for storing filamentary material with the first accumulator unit receiving filamentary material from the source and storing a given amount of filamentary material and each succeeding accumulator unit storing double the amount of filamentary material stored by a preceding accumulator unit; varying the movement of the filamentary material between the accumulator units; and controlling the movement varying device to limit the change in tension of the filamentary material with changes in the acceleration or deceleration of the filamentary material caused by a change in the input or output of filamentary material to or from the accumulator system.

Abstract: An automated circuit board testing system, for performing in-circuit, functional or cluster tests, takes backdrive stress into account in selecting appropriate isolation methods for digital devices during the design of the test protocol. In other words, the design of the test includes an analysis of the circuit board and its components, and of the available methods to isolate the device- or function-under-test from the rest of the circuit board. The analysis includes a calculation of stress currents on upstream components resulting from backdriving, and a selection of methods from those available which will produce stress currents below a pre-selected level. In another aspect of the invention, the safe maximum run-time for the test using the available methods is computed.
