Abstract: A vehicle air brake system is presented with an improved service work brake arrangement. The arrangement may provide a service work brake function or both a service work brake function and a parking brake function for the vehicle. The arrangement may provide an improved service work brake arrangement disposed within a housing for reducing the number of components and plumbing required to achieve this functionality versus prior known systems. The arrangement may utilize a pneumatic latching valve to deliver pressurized air for applying a vehicle's service brakes. The pneumatic latching valve opens upon receiving a pneumatic control signal from an electronically controlled valve and closes upon receiving a pneumatic control signal from another source. In addition, a controller and control logic may be provided for controlling the arrangement.

Abstract: Electronic elements (44, 44?, 44?) having an active device region (46) and integrated passive device (IPD) region (60) on a common substrate (45) preferably include a composite dielectric region (62, 62?, 62?) in the IPD region underlying the IPD (35) to reduce electromagnetic (E-M) (33) coupling to the substrate (45). Mechanical stress created by plain dielectric regions (36?) and its deleterious affect on performance, manufacturing yield and occupied area may be avoided by providing electrically isolated inclusions (65, 65?, 65?) in the composite dielectric region (62, 62?, 62?) of a material having a thermal expansion coefficient (TEC) less than that of the dielectric material (78, 78?, 78?) in the composite dielectric region (62, 62?, 62?). For silicon substrates (45), non-single crystal silicon is suitable for the inclusions (65, 65?, 65?) and silicon oxide for the dielectric material (78, 78?, 78?).

Abstract: Electronic elements (44, 44?, 44?) having an active device region (46) and bonding pad (BP) region (60) on a common substrate (45) desirably include a dielectric region underlying the BP (35) to reduce the parasitic impedance of the BP (35) and its interconnection (41) as the electronic elements (44, 44?, 44?) are scaled to higher power and/or operating frequency. Mechanical stress created by plain (e.g., oxide only) dielectric regions (36?) can adversely affect performance, manufacturing yield, pad-to-device proximity and occupied area. This can be avoided by providing a composite dielectric region (62, 62?, 62?) having electrically isolated inclusions (65, 65?, 65?) of a thermal expansion coefficient (TEC) less than that of the dielectric material (78, 78?, 78?) in which they are embedded and/or closer to the substrate (45) TEC. For silicon substrates (45), poly or amorphous silicon is suitable for the inclusions (65, 65?, 65?) and silicon oxide for the dielectric material (78, 78?, 78?).

Abstract: A fitting for a tube or pipe capable of functioning a high pressures having a first fitting component adapted to receive the conduit end; a conduit gripping device such as a ferrule or ferrules and a second fitting component that can be joined to the first fitting component to cause the conduit gripping device to grip the conduit and seal when assembled. In one aspect of the invention, the first fitting component is constructed from a material that is softer than the material used to construct the second fitting component. An additional aspect of the invention include a retaining portion on the second fitting component that constrains the tube gripping device against pressure. The retaining portion can also be configured to retain the tube gripping device to the second fitting component prior to installation and in a finger-tight condition.

Abstract: A submersible electromagnetic (EM) field generator for seafloor electromagnetic surveying comprising an AC to DC converter operable to generate a DC output from an AC input and a switching module operable to generate a waveform driving signal by selectively switching the DC output. The EM field generator also comprises an antenna that is operable to generate an EM field in response to the waveform driving signal. This design approach of using a switched DC source allows square or rectangular wave EM signals to be generated which have sharp transition characteristics and which are substantially independent of the AC input characteristics.

Abstract: A tube fitting for a tube end has a first coupling member and a second coupling member joined with the first coupling member. A tube gripping device is disposed between the first coupling member and the second coupling member such that assembly of the first coupling member with said second coupling member to a pulled-up condition causes the tube gripping device to be plastically deformed and swaged into the tube to grip and seal the tube. The first coupling member engages an internal surface of the second coupling member to provide an indication of completed pull-up.

Abstract: A brake valve actuator (BVA) of a vehicle is controlled by an electronic control unit (ECU) to provide automatic traction control (ATC), roll stability (RS) and yaw stability (YS) functions for the vehicle, by actuating the dual brake valve without driver intervention. The ATC function is provided by making braking pressure available at the driven wheels only of the vehicle. This may be done by selectively controlling the modulators for the driven wheels and the non-driven wheels of the vehicle. The ATC function in this manner can be provided for a straight truck or bus, or for a tractor and trailer, without the need for an ATC solenoid. In another embodiment, a yaw control function is provided, without the need for ATC solenoids or for pressure sensors in the delivery lines. In yet another embodiment, yaw control benefits are provided with an additional sensor.

Abstract: A tube fitting for a tube end has a female threaded member that cooperates with a male threaded member. The female member includes a tube gripping device in the form of a gripping ring or ferrule that is attached to the female member by a frangible web. Upon a partial pull-up the ferrule engages a camming surface on the male threaded member and breaks off or separates from the female threaded member to become a separate piece so that the fitting then functions as a single ferrule tube fitting. Additional features include a steep camming angle on the camming surface to cause the ferrule to grip the tube end with a bite-type action and to form a primary seal between the camming surface and a front end of the separated ferrule. The ferrule front end, and optionally the entire female threaded member including the initially integral tube gripping device, are hardened to be at least about 3.3 times harder than the material of the tube end.
