Abstract: An interface is provided between a digital signal processor or the like and an output encoder or the like that is capable of counting a system clock of the digital signal processor, generally having a higher clock rate, with respect to at least one or more clocks generally having a lower clock rate. The digital signal processor system clock is passed to the interface that has at least one or more counters. When the accumulation of the system clock reaches a corresponding number of the other clocks, a domain module in the output encoder is triggered, and the corresponding clock counters are reset. The interface may be implemented as a software modeling routine suitable for utilization by a digital signal processor simulator to facilitate complete whole cycle simulation in which multiple clocks having various clock rates may be simulated and compared with a behavior reference. The interface provides cycle-by-cycle comparison of the clocks in an asynchronous domain.

Abstract: A pad sander skirt which flares out over the periphery of the sanding pad and which is coupled to a lower housing so that it swivels about the body of the sander. The skirt and lower housing can be selectively swivelled in a rotational manner to a position desired by the user. A further sander improvement disclosed relates to the protection of a user's hand. Palm-grip random orbit sanders are sometimes configured so that the sanding pad may begin spinning at high speed when the sander is lifted off of the work. To this end, the present application discloses a protective skirt which flares out over the periphery of the pad in a palm-grip random orbit sander. Also disclosed is an improved dust collection system comprising a filter housing formed of a rigid porous material for entrapping dust.

Abstract: The present invention provides improved chlortetracycline-containing animal feed compositions and processes and apparatuses for their preparation. In certain embodiments, raw fermentation broth comprising chlortetracycline is divided into two portions. The first portion is mixed with a compound that complexes chlortetracycline. The second portion is acidified and the solids are removed. The acidified liquid is treated with a complexing agent to produced a chlortetracycline complex. The first and second portions thus treated are then mixed and the mixture is passed on to a filter press or other means for separation of the solids to produce a wet cake comprising complexed chlortetracycline. In alternative embodiments, the second portion may be acidified and filtered and admixed with the first portion prior to the complexing step. The resulting mixture is passed on to a filter press or other means for separation of the solids.

Abstract: The present invention is directed to a buffer improvement for higher speed operation. A buffer may include at least two buffer stages, which may include a first buffer stage and a second buffer stage. A voltage conversion circuit is disposed between the first buffer stage and the second buffer stage. The voltage conversion circuit is suitable for acting as a delay between the first buffer stage and the second buffer stage. Additionally, the first buffer stage may be driven directly, thereby increasing buffer speed.

Abstract: The present invention is directed to a system and method of modeling electrical circuits.

Further, the invention may provide for accurate prediction of resistance, capacitance and inductance for interconnections in a semiconductor, allowing for both environmental values and process variations.

Abstract: A portable data collection system employing a portable data terminal having increased functionality is disclosed. The portable data terminal includes an integral magnetic stripe reader for reading information magnetically encoded on a magnetic stripe card, such as a credit card or the like. An interchangeable feature pod may be attachable to the data terminal and may include a selected data collection or communication device such as, for example, a data communication port, optical indicia reader or laser scanner to facilitate data entry and communication. The interchangeable feature pod may include a compact, ergonomically efficient actuator for activating the selected data collection or communication device. Interconnection of the portable data terminal to interchangeable feature apparatus such as an electrical power supply, peripheral devices, or data communication apparatus may be accomplished via separate line connection, a port replication apparatus or a vehicle docking apparatus.

Abstract: A simulation test bench environment for testing a circuit is described. The test bench environment uses high-level task routines executed by one or more bus functional device models to generate input test vectors. A timing and protocol checker verifies both signal timing and functional operation bus specifications. Data and parity miscompares and corruptions are reported in real-time during simulation. An error and interrupt handler services errors and interrupts by communicating with the buses coupled to the circuit to execute specific recovery routines. A memory model is used to generate known expected data for data transactions, to store data from the circuit on data transactions, and to generate operation codes for the circuit.

Abstract: The present invention is directed to an apparatus suitable for mounting an integrated circuit (IC) including a frame suitable for receiving an integrated circuit (IC). The frame includes at least one leg coupled to the frame, the leg suitable for engaging a circuit board so as to enable the apparatus to be secured to the circuit board, thereby securing the integrated circuit (IC). At least one of the frame and leg include a conductive material so as to create at least one of a heat conducting path and an EMC ground path between the integrated circuit (IC) and the circuit board.

Abstract: The present invention teaches various femtosecond machining and drilling apparatus and processes for fabricating tools and the like from both traditional and non-traditional materials. Also described are novel tools such as scalpels, and nozzles fabricated from the apparatus and processes of the present invention. Likewise, the present invention may be utilized in both a novel propulsion system and the production of materials formed from nanometer sized particles and the like.

Abstract: A weather strip for use on a vehicle comprises an engaging portion for securing a weather strip to a vehicle and a weather strip body comprising a compressible portion and a magnetic sealing portion. The magnetic sealing portion provides a seal acting in a direction projecting toward a magnetically attractive substrate to provide a sealing interference between the magnetic sealing portion and the substrate when the weather strip is installed on the vehicle and a door closes the opening. The weather strips described herein provide an air and water tight seal without requiring a high compression force, thus improving door operation and reducing closing noise by eliminating the need to slam the door.
