Abstract: A hardware access layer (HAL) is combined with a configurable shadow mechanism, that copies the specified memory or register segments accessed in remote hardware by a program being debugged. The HAL may be involved in all interrupt handling for the remote hardware. By making this shadow mechanism configurable during runtime, and using a standard debugging techniques, a developer can specify watchpoints to break program execution based on changes in the remotely attached hardware as indicated in the specified shadow register segments.

Abstract: A pressure vessel for the storage of pressurized fluids for a fuel cell system, a liner for the pressurized vessel and a method of making. The method of manufacturing a pressure vessel includes forming a lost core assembly, a reinforcement structure around the assembly and removing the core from said assembly to define an internal compartment. The lost core assembly includes a first sacrificial material used to define the shape of the pressure vessel's internal compartment, boss attachable to the first material for the introduction and removal of the fluid into the pressure vessel, and a second material for placement around the first material and at least a portion of the boss such that upon removal of the first material, the second material defines the liner. The reinforcement structure is wound around the liner to give the pressure vessel a unitary, composite structure.

Abstract: Technique for initializing a data processing system. Sequences of initialization steps for selected functional hardware elements of a data processing system are defined and dependencies between the initialization steps are determined. These definition steps are preferably performed during the design and development of the data processing system. The sequences of initialization steps and their dependencies are represented in a single control flow table. This control flow table is then analyzed by a system management controller during an initialization phase of the data processing system. The sequences are associated with selected functional hardware elements and for each associated sequence of initialization steps the system management controller generates and executes a parallel thread of execution.

Abstract: Circuit arrangement for detecting the capacitance or capacitance change of a capacitive circuit element, has a control unit, a monostable multivibrator triggered by the control unit, and an evaluation unit. The monostable multivibrator has an input connected to the control unit, a second input connected to the sensor capacitor, and an output. When the monostable multivibrator is triggered by the control unit, an output signal appears at the output of the monostable multivibrator having a time duration proportional to the capacitance of the sensor capacitor, and is converted into a signal voltage proportional to signal duration from which a detection value corresponding to the capacitance or change of capacitance is obtained in the evaluation unit. The output of the monostable multivibrator is to a constant current generator that is controlled by its output signal and an integrator that converts the current from the constant current generator into the signal voltage.

Abstract: A capacitive proximity switch for detecting the change in the capacitance relative to a setpoint capacitance by the approach or retreat of an object in the sensitive area of a proximity switch, especially for use in the door handle of a motor vehicle, provides reliable error detection and error suppression at a fundamentally high sensitivity of the capacitive proximity switch by utilizing an evaluation unit that evaluates a measured value of the change in capacitance over time and depending on the time behavior of the measured value activates changes the operating threshold from a first threshold (which can be caused by a false object coming into or out of the sensitive area of the proximity switch) to a higher second threshold which can be reached only at a relatively greater change in capacitance caused by a target object coming into or out of the sensitive area of the proximity switch.

The gripping system includes an active jaw and two passive jaws disposed interior to the rotary. Preferably, the two passive jaws are separately by less than 120 degrees from each other and are pivotally connected to rotary. The gripping system is adapted and arranged to allow each passive jaw to react the same amount of force as the gripping force applied by the active jaw. In another embodiment, a rotary locking apparatus is provided to lock or unlock the rotary of the tong.

In one aspect, the present invention provides a wrenching head for supplying torque over a large step less clamping range for connecting tubulars. In one embodiment, the wrenching head includes hydraulic clamping cylinders guided by pendulum bolts. The pendulum bolts prevent the piston from twisting or bending under a high clamping force.

The jaw body includes a gear profile formed on an outer surface. A turn ring having a gear profile for mating with the gear profiles of the jaw body may be rotated to cause all of the jaw units to adjust simultaneously. In another aspect, the present invention provides a suspension unit to couple a spinner to the wrenching unit.
