Abstract: An improved capacitive sensor for detecting the presence of objects in a sensing region. The sensor is a multilayer structure with alternating layers of conductive and insulating materials. The sensor structure has three electrodes; a touch plate (25), a guard layer (15), and a ground plane (5), each of which are separated from each other by insulating layers (20, 10). The sensor is operated by detection electronic circuitry which function in either a self excited mode or an externally excited mode. This sensor is capable of detecting objects in a sensing region several feet away from the sensing surface and is particularly suitable for automobile applications, such as detecting potentially jamming objects in power (auto-closing) windows, doors, and the like.

Abstract: A new category of mobile communications antenna is implemented in a single layer of conducting material. Wire-slot sections, including wire-tabs defining slots in the material, partially extend around the perimeter of at least one patch-tab section of the antenna. The perimeter of the at least one patch-tab section forms one edge of each slot, and the wire-tab of a wire-slot section forms a second edge of the slot. The wire-tabs of the wire-slot sections are separated from the patch-tab section by the slots and merge into the patch-tab section at a desired point. The length of each of the wire-slot sections may vary. A portion of each of a pair of the wire-tabs of the wire-slot sections functions as an input feed. The patch-tab section may be implemented as a single tab or as a plurality of tabs separated from one another by a slot. By varying the relative geometries of the patch-tab, wire-slots and tabs of the wire-slots, the electrical properties of the antenna, including the input impedance, can be adjusted.

Title: Tubular container with heat seal having an inner and outer bead and method of manufacturing said container
Inventor: WILLIAMS ALAN D
IPC: B31B50/64
Filed: 1999-04-12
Granted: 2003-09-09
Abstract: A method of manufacturing multi-ply tubular containers for food products is provided including the steps of applying an aqueous adhesive to a surface of a paperboard body ply and then heating the aqueous adhesive to evaporate part of the water content and render the adhesive substantially tacky. The body ply and a polymeric liner ply having a moisture barrier layer are then either fed to a shaping mandrel from opposite sides and bonded together as the container is formed on the mandrel or are first passed through a nip to adhere the liner ply to the body ply and then wrapped around the mandrel as a laminate to create the tubular container. Accordingly, an advantageous tubular container can be manufactured having a body ply formed of paperboard which is wrapped into a tubular shape to define an inner surface. The body ply defines a predetermined circumferential length before being wrapped which corresponds to one revolution of the body ply when wrapped in a tubular shape. A polymeric liner ply is adhered to the inner surface of the body ply and defines a circumferential length equal to that of the body ply prior to being wrapped. Accordingly, the liner ply is circumferentially compressed when the body ply is wrapped into the tubular shape and advantageously has a wrinkled surface finish after being wrapped which is caused by the circumferential compression of the liner ply. Another feature of the invention is a sealed composite container having an end seal formed by a pair of inner and outer beads of a heat flowable polymer forming a part of the liner and membrane-type lid.

On peut aussi prévoir des moyens d'élimination de cires parasites et/ou autres condensats par évacuation centrale, en utilisant le conduit central. Suite à l'augmentation dans ledit conduit de la vitesse de l'air de refroidissement brusque, les courants tendent à améliorer l'écoulement global de cet air en déviant les flux opposés pour qu'ils forment un flux uniforme. Dans d'autres variantes figurent la division dudit air en zones d'écoulement susceptibles d'être contrôlées indépendamment et la variation de l'angle d'écoulement de l'air en question et/ou des plaques de filature, de manière à maintenir un espacement entre l'air considéré et les faisceaux de filaments.

Abstract: A method and system for dynamically managing billing information for telecommunications service application use at the service application level rather than at the billing system level. Each service application, such as a call forwarding service application, is programmed with application level data records in which are stored the parameters of a given promotion, such as number of free uses, the start time and stop time of the promotion or rental period, etc. Each time a service application is subsequently used, the customer's use of the service application is logged in a customer data record. The customer's use is then compared to a corresponding application level data record. Based on this comparison, a billing record is provided to the billing system which instructs the billing system to either bill or not to bill the customer for the particular use of the service application.      No adjustment of the billing system is required for particular service application use because the billing system will receive a billing record with instructs, it to bill or not to bill. A record for each use of the service may be placed on the customer's bill, but only those uses for which the customer is to be charged will have a corresponding cost entry.
