Abstract: A frangible grease cap for use in a collapsible constant velocity joint. The frangible grease cap includes a body generally having a circular shape. The frangible grease cap includes an orifice through a center section of the body. The grease cap also includes at least one reduced thickness groove on a surface of the body of the constant velocity joint grease cap. The grease cap has a circumferential flange extending from an end thereof. The grease cap includes reduced thickness grooves having predetermined shapes which will peel or rupture when a predetermined axial load is applied thereto. The grease cap is secured to an inner surface of an outer race through any known securing method which also influences when the grease cap will fracture during or completely release during a crash event when a predetermined axial load is applied thereon.

Abstract: Methods and systems for applying digital dither in data converters, such as delta-sigma data converters. In one embodiment, an analog signal from a first path of a delta-sigma modulator is quantized to an m-bit digital signal and an n-bit dithered digital feedback signal is generated from at least a portion of the m-bit digital signal. The n-bit dithered digital feedback signal is converted to an analog feedback signal and fed back to a second path of the delta-sigma modulator. In another embodiment, the n-bit dithered digital feedback signal is generated by selecting one of a plurality of sets of n-bits from the m-bit digital signal depending upon a state of a dither control signal. The dither control signal can alternate or pseudo-randomly switch between a plurality of states. The m-bit digital signal may be an m-bit thermometer code signal.

Abstract: Methods and systems for improved feedback processing in delta-sigma modulators, including single bit and multi-bit delta-sigma modulators, continuous-time and discrete-time delta-sigma modulators, and digital and/or analog feedback loops. One or more processes are performed in a pipeline having a higher throughput rate than a throughput rate of a delta-sigma modulator. Any of a variety of processes and combinations of processes can be performed in the pipeline including, without limitation, quantization, digital signal processing, and/or feedback digital-to-analog conversion.

Abstract: In a method, apparatus, and computer-readable medium, interfacing between middleware software and application software uses a plug and socket approach in which application-specific services and resources are isolated into the plug and middleware-specific components are isolated into the socket. The plug and the socket communicate with each other through an interface. The socket communicates with middleware software through an application program interface, and the plug communicates with application software through an application program interface. Therefore, the plug is isolated from communicating with the middleware software, and the socket is isolated from communicating with the application software.

Abstract: A machine for forming T-shaped tubular components comprises a plurality of successive stations. A tubular blank having a forming material insert therein is positioned within a T-shaped die in a first station. A bulge is formed in the blank as force is applied to the ends or runs of the blank and the insert from opposing punches. Once the bulge or outlet of the T-shaped component is formed, a hollow pointed punch is driven through the outlet to open it. All of the punches are removed, the die is opened and the partially formed T-shaped component is transferred to a second station for cleaning. A broach is driven into one of the runs of the component while a punch is driven into the outlet. The forming material in the outlet is driven towards the runs of the component by the punch so that it is carried out the other one of the runs by the broach together with the forming material in the runs.
