A film product and a method of making the same are provided, the film product comprising a metallocene catalyzed polypropylene and a tenacity of at least about 2.5 g/den is provided. The film product is capable of being drawn at a draw ratio of from about 5.0:1 to about 10.0:1. The film product is also capable of being processed into a slit tape product. A method of weaving a woven product from the slit tape product is also provided, wherein the woven product may have a tenacity within about 10.0 percent of the tenacity of the film product.

In some embodiments, a user may select an elemental function such as read, write, or configuration from a graphical programming environment. A file may be created that instantiates functionality into a programmable hardware element to allow it to send a command across a serial protocol to peripheral interface circuitry and ultimately to peripheral chips (e.g., network chips on a CAN). The elemental node concept may be generic to any network chip because the node may contain only the general data of a packet (e.g., command type, value of data bytes, etc). The actual interface to a network chip may be handled inside the peripheral interface circuitry. The peripheral interface circuitry may have the details of the network chip in which it interfaces and may abstract details of the network chip from the target programmable hardware element through the serial protocol.

A modular telecommunication test system is presented including a portable computer system and at least one portable telecommunication test module located external to the computer system. The portable computer system stores a telecommunication test application (e.g., in a memory system). Each test module includes a communication port having an electrical connector, and is thus adapted for coupling to the portable computer system. Each test module also includes electrical circuitry for performing a set of telecommunication tests, wherein each test involves making at least one electrical measurement upon a telecommunication service installation. In coupling a given test module to the portable computer system, a user configures the test system to perform the set of telecommunication tests associated with the given test module. The at least one test module is selected from a group of test modules, each configured to perform telecommunication tests upon a different type of telecommunication service installation. Eligible types of telecommunication service installations include POTS, T1/E1, ISDN, and xDSL. The test system may also include a second computer system (e.g., a desktop computer system) coupled to the first computer system via a communication network. The communication network may include the PSTN and the Internet. The first computer may receive telecommunication test data from each test module and provide the test data to the second computer system via the communication network.
摘要:
A system and method for controlling access to a dual port shared memory in a system comprising a host computer system and a communication device comprised in or coupled to the host computer system. The communication device includes the shared memory and also includes a local processor which executes a communication application. The shared memory is accessible by both the host computer and the local processor on the communication device. The board or local processor has deterministic and/or real time requirements and is thus the high priority requester, while the host CPU or host computer is the low priority requester. If the high priority side (board) gains the semaphore first, then accesses by the low priority side (host computer) are blocked until the write is finished. In the case of a host read/board write, if the low priority side gains the semaphore first, then the high priority side write can pre-empt the low priority side read. In this case, to avoid data integrity issues, the low priority side is required to verify that it still owns the semaphore after it finishes its read access, and the access fails if the low priority side does not own the semaphore at the time the read is completed. In the case of a host write/board read, if the low priority side gains the semaphore first, then the high priority side does not simply pre-empt to the low priority side as in the high to low data transfer direction. Rather, in this instance, when the high priority side determines that the low priority side owns the semaphore, the high priority side reads previously read data from a local buffer.
