Abstract: A process for manufacturing a MOS device includes forming a semiconductor layer having a first type of conductivity; forming an insulated gate structure having an electrode region, above the semiconductor layer; forming body regions having a second type of conductivity, within the semiconductor layer, laterally and partially underneath the insulated gate structure; forming source regions having the first type of conductivity, within the body regions; and forming a first enrichment region, in a surface portion of the semiconductor layer underneath the insulated gate structure. The first enrichment region has the first type of conductivity and is set at a distance from the body regions.

Abstract: In a network, packets are fragmented into head and non-head fragments. Non-head fragments are saved up front at an entry point, while a network switch forwards only the head fragment to Layer 4-Layer 7 (L4-L7) features for processing. The switch records changes that are performed on the head fragment's fields by the L4-L7 features while they process the head fragment. At an exit point, fields of the saved non-head fragments are overwritten with information that was recorded for the head fragment. This can include updating or modifying the source and destination parameters of the non-head fragments in an intelligent manner by reusing the results of the packet processing that was performed on the head fragment. This fragmentation handling technique avoids having to redundantly process the non-head fragments in the same manner as the head fragments.

Abstract: A toroidal cushion sized to fit and support a posterior of a human user. The toroidal cushion slopes significantly from the back toward the front and comprises an upper cushion surface comprising a depressed center within a surrounding upper cushion surface. The depressed center and the surrounding upper cushion surface are configured such that the user's weight is essentially supported by the surrounding upper cushion surface whereas the depressed center is substantially non-body-weight-bearing and provides an upward force that contacts and supports a rectal area of a user when the toroidal cushion is sat upon.

Abstract: Embodiments of the present invention relate to a system for clock synthesis or data timing recovery. No analog continuous time oscillator is required, all the building blocks of a Frequency Locked Loop/Phase Locked Loop belonging in the digital discrete time domain. From a system-level perspective, the system is characterized by its strong non-linear behavior due to the intrinsic nature of some building blocks. This inherent non-linearity is responsible for some unusual, attractive property of the complete system. The system is able to multiply the input frequency clock by an arbitrarily large factor, ensuring in any case the convergence of the algorithm in two reference clock cycles.

A push-pull stage includes first and second control inputs and an output. The push-pull stage is coupled to the biasing circuit to receive the first and second biasing signals on the first and second control inputs, respectively, and is coupled to the capacitive network to receive the first and second bootstrapped signals on the first and second control inputs, respectively. The push-pull stage is operable to generate a buffered output signal on the output responsive to the first and second bootstrapped signals.

Abstract: An embodiment of an electronic component includes a circuit element disposed within a package, which includes a surface and at least one standoff protruding from the surface. For example, where the circuit element is an inductor in a power supply, the standoff may allow one to mount the inductor component over another component, such as a transistor component. Therefore, the layout area of such a power supply may be smaller than the layout area of a power supply in which the inductor and transistor components are mounted side by side.

Abstract: A sensor for detecting surface cracks in a component or structure. A preferred embodiment of the device comprises a flat body portion with a central hole through which a main structural bolt passes. The body portion has a throughway providing fluid communication between an exterior port and a substantially hermetically-sealed area on the structural surface being monitored. A crack which develops in the monitored area surrounding the bolt hole will cause venting of the hermetically-sealed area, in turn causing a change in fluid pressure that can be detected and/or measured to warn of the presence of the crack.

Abstract: High-speed transceiver devices, such as GBIC-type transceivers, are accessed and addressed. Identification information (including manufacturer name, model, compliance codes) is placed in data fields of the transceivers. An algorithm checks each port in each module of a host system to determine if a transceiver is present. If a particular transceiver is present, then algorithms store the port address of the transceiver in memory and enable the transceiver to be read from or written to. Reading from the transceiver includes reading the identification information, and writing to the transceiver includes writing the identification information. If a transceiver is initially determined not to be present or if the reading/writing/enabling processes fail, then a recovery process determines if the transceiver was present the last time it was checked. If it was present the last time, then the process continues to try to recover the transceiver data—otherwise, the port is marked as empty.
