  • Patent number: 7119526
    Abstract: A voltage monitor having a bandgap reference circuit driven by a voltage to be monitored. The bandgap reference circuit produces a voltage and a second voltage that each vary with the voltage to be monitored. The magnitudes of these voltages are compared by an open loop comparator to provide a high speed output state. The output of the voltage monitor can be used to monitor a supply voltage and produce a reset signal to a processor if the supply voltage falls to a magnitude below a specified threshold.

  • Patent number: 6757715
    Abstract: 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.

  • Patent number: 6678801
    Abstract: A multi-processor system includes a global bus (14) having associated therewith a global address space with a plurality of processor nodes (10) associated therewith. Each of the processor nodes (10) has a CPU (20) associated therewith which interfaces with a local bus. The local bus has a local address space associated therewith. A dual port SRAM (DPSRAM)(34) is provided for interfacing between the global bus (14) and the local bus (30). Each DPSRAM (34) for each processor core (10) has a defined address space within the global bus address space. Whenever any of the global resource writes to the particular processor node (10), it is only necessary to address the designated DPSRAM (34) and transfer data thereto. The act of transferring the data thereto will generate an interrupt to the associated CPU (20) which will then cause it to read the received data on the local bus by addressing its associated DPSRAM (34).

  • Patent number: 6643692
    Abstract: A method for allowing a user PC (1702) to be controlled in order to effect a connection between the user PC (1702) and a destination node (1706) on a network (306). This is facilitated through an audio source (1700) wherein the content of a video tape recording media has embedded therein an audio signal. When the video tape media is played, the audio signal is extracted by an audio extractor (1600) and transmitted to the user PC, and detected by a program running in the background of the user PC (1702). Once the audible tone is detected, a web browser is launched and the tone or decoded product identifier information associated with the tone is transmitted to an ARS (308) on the network (306). The ARS (308) then compares the information received from the user PC (1702) using information from a relational database (1704). The relational database (1704) contains routing information for various destination nodes (1706) on the network.

  • Patent number: 6642877
    Abstract: A method is disclosed for forming resistor strings in a semiconductor material for a digital-to-analog converter having a main DAC resistor string and a sub-DAC resistor string. The main DAC resistor string is formed as two identical resistor strings connected in parallel and such that the bottom of one resistor string and the top of the other resistor string are connected to a first voltage. The other ends of the resistor strings are coupled to a second different voltage. A switch multiplexer serving two functions is connected between the resistor strings. Each switch of the multiplexer interconnects similar voltage nodes of each resistor string together to thereby average the voltage should the resistance values differ due to semiconductor process variations. The switch multiplexer also serves to select one resistor of each resistor string to couple the voltage thereacross to a sub-resistor string of the digital-to-analog converter.

  • Patent number: 6636892
    Abstract: A method for conducting a contest using a network is provided. A plurality of pick spaces and a rolling counter are displayed on a screen of a computer operably connected to the network at a user site. The rolling counter constitutes successive ones of a plurality of available characters, each character being displayed for a preselected duration. Each time the user performs a predefined selection action, the then-displayed character of the rolling counter is assigned to a successive one of the plurality of pick spaces, and thereafter the assigned character is displayed in the corresponding pick space. When each pick space displays an assigned character, an entry data packet is assembled including data indicative of the assigned character in each of the plurality of pick spaces. The entry data packet is transmitted from the user computer across the network to a remote site. The entry data packet is received at the remote site.

  • Patent number: 6636326
    Abstract: A method is disclosed for calibrating the half-tone operation of a color marking engine for creating images formed in bi-level or quad-level dot density formats. In the first step, a test pattern is run to provide an output image of a plurality of gray patches formed of first, second and third color toners. The gray patches of the output image include first, second and third sets of patches reproduced respectively at dot density levels of 25%, 50% and 75% of a maximum dot density. The relative color toner levels in the gray patches within each set of patches varies a predetermined increment in value above or below the toner levels in a median valued gray patch. The remaining steps of the method include visually selecting an output image of a selected color marking engine having a minimum color shift; determining a correction factor defined for each color at the maximum dot density; and storing the correction factor as an offset from maximum density for images created at the bi-level and quad-level formats.
