Abstract: A device for measuring the flow of a fluid has a primary duct and a bypass arranged in series to the primary duct. The bypass has a first section and a second section. A baffle plate with a hole for the passage of the fluid is arranged in the first section. The second section comprises two parallel secondary ducts. In the first section, a turbulent flow dominates, while the flow in the second section is primarily laminar. If the turbulent effects in the bypass are sufficiently strong, the ratio of the flows in the primary duct and the bypass can be substantially independent of the fluid properties and of the flow rate. By using two parallel secondary ducts in the second section, high flow rates and therefore strongly turbulent effects can be achieved without exceeding the measuring range of the sensor.

Abstract: A flow detector comprises at least two housing parts with a semiconductor chip having an integrated flow sensor arranged between the housing parts. An opening is provided in one of the housing parts and at least one metal pin extends through the opening and forms an electrical lead-through. A hardened filler material is used for sealing the lead-through against the walls of the opening. This construction provides a well sealed cavity for the fluid to be measured and can be manufactured easily.

Abstract: A sensor is described for measuring the parameters of a fluid, in particular for detecting substances in a gas. It comprises a measuring section (4) on a semiconductor chip (1), which is protected by a housing (3). A partition wall (12) of the housing (3) divides the semiconductor chip (1) into two parts (1a, 1b). The first part (1a) is connected to the outside by means of openings in the housing and carries the measuring section. The second part (1b) is covered by a hardened sealing material (11). The sealing material (11) protects the semiconductor chip (1) from undesired environmental influences. The dividing wall (12) forms a capillary between the chip and the housing, the capillary action of which draws in the sealing material and the end of which stops the sealing material.

Abstract: For measuring the flow and the thermal conductivity of a fluid, a sensor is used, which has a first temperature detector for measuring a first temperature and a second temperature detector for measuring a second temperature. A heating is arranged between the temperature detectors. Two measured quantities are determined by means of the temperature detectors, a first of which is e.g. a difference between the temperatures and a second one of which is one of the temperatures. By comparing the two measured quantities, the flow and the thermal conductivity of the fluid can be determined.

Abstract: A client/server navigation system utilizes partial route guidance trees, enabling a thin, mobile client to detect route deviation and provide alternate instructions while awaiting response from a server. The system (10) consists of a server (28) containing a network database and route-calculation program; a client (26) capable of obtaining (12) its current location and destination, displaying route instructions (22), and determining when it needs additional instructions from the server (20,24); and communication (30,32,34,36) between the client (26) and server (28). The invention allows for long routes and responsive operation on a small, low-powered client despite lags and lapses in communication.

Abstract: An expansible occupant restraint cushion is provided. The restraint cushion includes a first section of material having a plurality of perimeter edges and "Z" profile lap structures disposed along selected perimeter edges. Each "Z" profile lap structure includes a first fold formed along a fold line in opposed relation to a perimeter edge and a second fold reverse in direction to the first fold formed along a fold line intermediate the fold line of the first fold and the opposing perimeter edge to yield an outboard attachment margin. The restraint cushion further includes a second section of material in opposed mating relation to the folded first section of material. This second section of material is adjoined to the first folded section of material at the outboard attachment margins of the "Z" profile lap structures. A related method for forming the cushion of the present invention is also provided.

Abstract: A process to provide a patterned, laminated fabric in which an inner foam layer is embossed to hold the pattern in the outer decorative layer in position. The process continuously cold embosses the flame laminated fabric to allow continuous formation of the subject fabric at an acceptable rate of speed.
