Abstract: Disclosed is an approach to implement a multi-tenant DNS resolver for secure communications for a virtual cloud environment. The approach can perform split-horizon DNS forwarding via an intermediate customized DNS server.

Abstract: An interfacing structure for a mask system includes a cushion component adapted to contact the patient's face in use and a cushion-to-frame component provided to the cushion component. The cushion-to-frame component is structured to secure the cushion component to a mask frame of the mask system. The cushion-to-frame component includes a cushion side adapted to interface with the cushion component and a frame side adapted to interface with the mask frame. The cushion side includes a platform to engage and support the cushion component. The platform provides an engagement surface to engage the cushion component and inner and outer flanges provided to opposing ends of the platform to guide, support and/or retain the cushion component on the platform.

Abstract: A limited slip differential transmission of the closed type in which a pressurized lubricant is fed to the rotating gears and a series of limited slip clutch plates. The clutch plates are engaged by pressurized control fluid. A valve assembly having a spool valve is responsive to engagement pressure to permit discharge of a portion of pressurized fluid from the clutch plates to a sump chamber and the transmission to purge debris that may have accumulated in the clutch plates. The spool valve is arranged so that fluid is passed only during an intermediate movement of the valve to minimize any pressure loss from the lubricating fluid for the transmission and limited slip clutches.

Abstract: A poly-phase electric energy meter comprises a front-end that converts analog current input signals and analog voltage input signals to digital current and voltage samples and a micro-controller for computing power consumed. The front end includes first and second input channels. Each input channel has a multiplexer, an analog-digital converter, a de-multiplexer and a set of data registers. The first input channel receives current input and the second input channel receives voltage inputs. A multiplexer control causes the first and second channels to sequentially sample the current and voltage for one phase at a time and store digital data in corresponding data registers. The micro-controller computes energy consumed from the simultaneous current and voltage samples.

Abstract: A simplified and improved clutch piston, retractor system is provided for controlling the running clearance of clutch plate(s) to minimize windage loss and to improve transmission shift quality. This improved shift quality helps improve operator's comfort reduce shock loads on power transmission components, and reduce the energy input to the clutches when changing gears during the acceleration and deceleration of the vehicle. The clutch piston retractor system is self adjusting to accommodate wear to the clutch disks and optimize the shift quality, while compensating for the additional travel distance. Thus, the need to periodically recalibrate the entire system is eliminated.

Abstract: A brake assembly for a vehicle, such as an agricultural vehicle, having a brake housing and a brake cover defining a friction chamber. A brake piston is arranged within the friction chamber and coupled to the brake cover by at least one bolt having a sleeve in frictional engagement with a bore of the brake piston. The sleeve has a slip fit engagement with a bolt head and further includes a shoulder opposed to a retainer being axially spaced therefrom by a distance exceeding an axial height of the bolt head by an amount equal to an optimal running clearance. An actuation system is coupled to apply an axial force to the brake piston, the axial force being greater than the frictional fit of the sleeve to the bore in order to adjust a running clearance of the brake assembly to equal the optimal running clearance.

Abstract: Methods, systems and articles of manufacture for software implemented timers configured to account for purposeful or desired program stoppage. Such program stoppage is a common occurrence in debugging environments. Because such program stoppage is not indicative of an error condition, it is undesirable to include the stoppage time with the elapsed timer value. Accordingly, a process counter is implemented which is incremented only while a process of the application being debugged is executing.

Abstract: A system and method are disclosed for testing a device driver on a data processing system. An operating system allocates a memory address range for executing a device driver. The device driver is executed as an application on top of the operating system to test the device driver. The system and method monitor to detect whether a target address for a request made by the device driver is within the memory address range. In response to detecting the target address for the request being made outside of the memory address range, the target address is trapped, and a data exception handler is executed to emulate a target device.

Abstract: A method for conducting backside failure analysis on a wafer that only requires simple bias conditions to be fed into defective IC dies and a wafer test specimen which enables such test are disclosed. In the method, a wafer can be first provided that contains at least one defective IC die in an active (or front) surface, at least two conductive metal strips formed of a metal foil are then adhesively bonded to the active surface of the wafer juxtaposed to the at least one defective IC die. At least two lead wires are then bonded by a wire bonding technique between the at least two conductive metal strips and at least two bond pads on the defective IC die for establishing electrical communication therein between. A bias voltage such as a VCC signal or a clock signal can then be fed to the defective IC die through the at least two conductive metal strips, while the defect being observed from the backside of the wafer with an optical detector.
