    摘要: A DC to DC boost converter circuit receives a DC input voltage and converts it to a DC output voltage at a different voltage level than the DC input voltage. The DC to DC boost converter includes a switching power converter for receiving the input voltage on an input and converting the input voltage to an output as the DC output voltage in response to pulse control signals. A switching controller generates the pulse control signals during a switching cycle. Current sensing circuitry limits a current passing through the switching power converter. The current sensing circuitry generates an overload signal when the current exceeds a reference value. The current sensing circuitry sensing the current with a current sensing resistor having a size of at least approximately 500 ohms.

    摘要: An integrated circuit having an embedded multiple time programmable memory includes a processing core for executing stored instructions with a data memory and a non volatile memory. The non-volatile memory block provides for storage of program instructions and includes a plurality of blocks of non-volatile memory, each of which can be written to once and read from many times and each having a size that is equal to or less than a program memory address space addressable by the processing core for output of data there from. It also includes a reserve storage location for storing a status word defining the one of the plurality of blocks addressable by the processing core, the status word operable to be changed in response to external signals when another of the plurality of blocks is to be selected, such that once another of the plurality of blocks is selected, the status word cannot indicate as addressable by the processing core a prior one of the plurality of blocks that was defined by the status word as being previously addressable by the processing core.

    摘要: An interlocking architecture for a software interface and a bar code scanner. Upon power-up, a handshaking operation is performed between a scanner (1600) having a scanner processor (2600) and a computer processor (2612) of a computer (302) based upon the code stored in the NV memory (2602) of the scanner (1600) and a unique code associated with the software interface running on the computer (302). A wedge (1608) is provided as an interface mechanism for the scanner (1600) and a keyboard (1610) to a keyboard port (2500) of the computer (302). The handshaking occurs through the wedge (1608) via a keyboard interface (2610) to the processor (2600) such that a successful handshake directs the processor (2600) to engage a switch (2604) which enables power to a sensing head (2606) for read optically encoded information. The software interface operates from a computer memory (2614) associated with the processor (2612) whereby an unsuccessful handshake using unique number of the software interface by the processor (2612) sends a disabling signal though the keyboard circuit (2618) through the wedge (1608) to the scanner processor (2600) to disengage the switch (2604) to drop power to the sensor head (2606). The handshaking operation is performed on a regular basis during system power-up to ensure that the original software interface and scanner (1600) are still in use.

    摘要: Method and apparatus for generating unique id packets in a distributed processing system. A method for facilitating processing over a network includes generating at a server location on the network a pointer that defines an information profile on the network. The pointer is then associated with the information profile, and the pointer and the associated information profile transmitted to at least two locations on the network. The pointer can then be transmitted to one of the at least two locations on the network from another location on the network during a processing operation on the network for the purpose of processing a network transaction at the receiving one of the at least two locations on the network, which network transaction requires the associated information profile, such that only transmission of the pointer is required for the processing operation.
