Abstract: L'invention concerne un circuit de protection électrique comprenant un coupe-circuit électrique à fusible présentant une brasure (3), et un circuit fermé à résistance électrique (10) connecté en série avec le fusible (1), le fusible et le circuit fermé étant montés sur un substrat (11). La brasure (3) fond à des températures élevées dues à la chauffe du substrat (11), et est entourée d'un matériau (8) prévu dans une région (9) délimitée par des barrières (7) et conçu pour la protéger de l'effet oxydant de l'air ambiant. Lorsqu'elle fond, ladite brasure (3) se rétracte sur les bornes de connexion (4a,4b) et interrompt la voie suivie par le courant. Le matériau (8) est thermostable à l'état solide, aux températures de fonctionnement normales du fusible. Le circuit fermé à résistance (10) comporte des voies électro-conductrices (12) interconnectées à des éléments de pontage (13) dont la résistance électrique est nettement inférieure à celle des voies électro-conductrices (12), ainsi que des éléments de compensation (14) pour régler la résistance du circuit fermé.

Title: Process for determining and using the quantity of filling press material in solid-liquid separation with a filter press
Inventor: HARTMANN EDUARD
IPC: B01D29/60
Filed: 1995-03-21
Granted: 2006-01-24
Abstract: A determination of the amounts of fill of material (7) to be pressed in the solid-liquid separation by means of a filter piston press with a pressure element (6) for several successive pressing operations is made with the aid of a consideration in the yield/output diagram. Under a presupposition regarding the position of characteristic curves connecting various operating points in this diagram and by the interposition of an imaginary operating point it is possible to determine the changes in yield and output for each pressing operation and therefore the amounts of refill to be used in such a way that a maximal product of yield and output results for the solid-liquid separation operations when predetermining free process values. The method provides an automatic adaptation of the fill time to the compressibility of the materials. By means of this it is made possible to feed in material (7) of very different compressibility automatically and without having to predetermine reference values in such a way that an optimal behavior is achieved in respect to the yield and the juice extraction behavior of a filter press.

Abstract: An interface apparatus is provided with a number of communication ports for providing a communication interface between a postage meter and a plurality of external devices, such as, a scale and a modem. A principal communications port connectable to the postage meter. A secure communication port is provided for receiving messages on a secure scale using encrypted protocol signals. The interface unit includes an additional number of unsecured ports for communication with unsecured devices such as a modem or an unsecured scale utilizing conventional protocol signals. The interface further includes a programmable microcontroller in bus communication with a random access memory, a non-volatile memory and a program memory, a first communication bus connecting the principal port to the microcontroller and a second communication bus connecting one or more of the second communication ports to the microcontroller. The microcontroller of the interface unit is programmed to establish a communication link between one of the second communication ports and the principal port pursuant to a communication request signal from the principal port identifying which of the second communication ports for communication. Conversely, the microcontroller can establish a communication link between the second communication port and the principal communication port pursuant to a communication request from one of the second communication ports. The messages being communicated are comprised of a number of message frames and each of the message frames has a header, one of headers being designated for message frames which are intended to be directed to the interface unit. The interface unit monitors the header portion of each message frame and stripping the message frames from the messages having the designated message frame header for messages intended as instructions for the interface unit. An established communication link can be interrupted when a message having the designated message frame header and message frame instructs the microcontroller to establish communication between the microcontroller and the postage meter through principal port.

Title: Variable referenced control system for remotely operated vehicles
Inventor: THORNBERG CHRISTOPHER ALLEN
IPC: G05D1/00
Filed: 1995-02-22
Granted: 2002-10-22
Abstract: A frame of reference is selected, and con- trol inputs provided by a vehicle operator are trans- formed to account for the orientation of a remotely operated vehicle with respect to the selected frame of reference such that the remotely operated vehi- cle responds to the control inputs with respect to the selected frame of reference. An earth frame of refer- ence may be selected based on a fixed true heading, e.g., North, or based on the initial orientation of the vehicle operator. Alternatively, a vehicle frame of reference may be selected which provides a fixed frame of reference with respect to the vehicle and a variable frame of reference with respect to the vehi- cle operator. A vehicle operator frame of reference may also be selected based on the orientation of the vehicle operator with respect to earth, and control commands are transformed based on changes in both the operator orientation with respect to the earth ref- erence and the remotely operated vehicle orientation with respect to the earth reference, which provides a fixed frame of reference with respect to the vehicle operator and a variable frame of reference with re- spect to the vehicle. The remotely operated vehicle heading transformation may be based on a selected forward, fixed or variable point on the vehicle re- lated to a vehicle center of gravity a forward part of the vehicle, the location of a sensor on the ve- hicle, or some other arbitrary reference location on the vehicle.

IPC: G01S3/00
Filed: 1996-01-29
Granted: 1999-09-21
Abstract: A method for wireless communication system planning includes, in a first embodiment, determining an image tree (500), based on a transmitter location (401) and the reflective (415) and diffractive (425) surfaces within a coverage region, and limiting the image tree to exclude branching for higher order im-ages requiring more than a predetermined number of reflections and/or diffractions, or potential child im-ages corresponding to surfaces not within the scope of the parent image (530, 560). Based on the im-age tree and propagation path back-tracing (620), a received signal quality measure (e.g., power) is de-termined for each receive location. By comparing the different received signal powers, an optimal receiver unit location is determined. Further, by building fur-ther image trees for further transmitter locations, an overall coverage quality can be determined for each transmitter and compared to yield an optimal trans-mitter location.

Abstract: A method, computer program product, and data structure is provided overcome excess code development associated with developing device drivers that are hierarchically related and provides standardization to driver developers by listing in the private area of a device object types of file objects, including specific IRP handlers associated therewith, that may be created under that device object to thereby provide a device object context. In like manner, each file object has listed in the private area types of other file objects, again including specific IRP handlers associated therewith, that may be created under that particular file object to thereby provide a file object context. The default handler for a driver object points to a multiplexing function that will process an incoming IRP based on the available context information to "route" the IRP to the appropriate handler. Each file object has reference to a plurality of dispatch function references that are used by the IRP handlers to fulfill a particular request. A request to create a file object will also be validated to assure that only file objects of the appropriate type may be created in hierarchy, again according to the context information.
