  • Publication number: 20250035393
    Abstract: An automatically ejecting magazine device includes an ammunition magazine which is substantially hollow for receiving ammunition for a firearm. A follower is movably disposed within the ammunition magazine to support ammunition for the firearm and a magnet is attached to the follower. A door is hingedly attached to the ammunition magazine and the door has a recess which is engaged by a magazine release of the firearm to retain the ammunition magazine in the firearm. The magnet urges the door into a disengaged position such that the recess is not accessible to the magazine release. In this way the ammunition magazine can drop out of the firearm when the last round of ammunition is fed into the firearm.

  • Publication number: 20070136623
    Abstract: A system, among other embodiments, includes a memory controller having an integrated BER circuit and a plurality of memory devices. The memory controller also includes a control circuit and an interface having at least one transmit circuit to provide write data to at least one of the memory devices and at least one receive circuit to receive read data from at least one of the memory devices. The BER circuit includes a request generator circuit that outputs a request for a memory transaction. A request multiplexer selectively outputs a memory request to the interface from the request generator circuit or the control circuit. A data generator circuit outputs corresponding write data. A first write multiplexer selectively outputs the write data to the interface from the data generator circuit or the control circuit. A read multiplexer selectively receives read data from the receive circuit. The data generator circuit also outputs corresponding write data to a comparator circuit via a second write multiplexer.

  • Publication number: 20060059392
    Abstract: An apparatus and method provides prediction of BER for an interface between ICs, such as a processor and a memory device, without using special test equipment. A known data pattern or PRBS is transmitted to a receiver, which compares the received data values with expected data values to determine if a bit error has occurred in an embodiment of the present invention. A center of data eye and the edge of the data eye are sampled (over sampled) in order to determine if a bit error has occurred in an alternate embodiment of the present invention. A first counter is used to count the total number of bits sampled and the second counter is used to count the number of errors that occurred in the total number of bits sampled. In an embodiment of the present invention, the first and second counters are logarithmic counters that include overflow protection. The counter values are output to a processing device to perform the BER calculation in an embodiment of the present invention.
