Title: Inventory system and control method using articles with rfid tags
Inventor: CLARE THOMAS J
IPC: G06Q10/08
Filed: 1998-07-15
Abstract: An article inventory control system for articles (22), such as books, uses RFID tags attached to each article (22). Each tag has a unique identification or serial number for identifying the individual article (22). An inventory database tracks all of the tagged articles (22) and maintains circulation status information for each article (22). Articles are checked out of the library (10) using a patron self-checkout system. Checked out articles (22) are returned to the library by being deposited into an exterior smart book drop (32) which reads the RFID  tag and automatically checks the article back in. Article data from the exterior smart book drop are used to generate reshelving reports for efficiently reshelving the articles. Articles which are used in the library (10), but not checked out, are returned to interior smart book drops (34) within the library (10) for reshelving. The interior smart book drops (34) capture data regarding in-house use of articles. The data are used to generate historical usage reports. The uncirculated articles (22) are stored on shelves of the library (10). The shelves are periodically scanned with an RFID scanner for updating inventory status.

Abstract: An electrical connector assembly for a power tool, a power tool and methods for assembling a power tool. A one-piece trace or spider terminal member assembly provides points of connection for the motor components, such as the field windings, the brushes and the switch. To assemble the motor, the terminal member assembly is positioned in the motor housing. To mount the terminal member assembly, the terminal member assembly is preferably co-molded with the housing or, alternatively, may snap-fit into connectors formed on the housing. The terminal member assembly and the housing are then preferably punched or stamped at points to provide the necessary number of electrically separated contact elements to connect the components of the motor. For example, the female ends or terminals of the field windings, the brushes and the switch are corrected to the electrically separated contact elements to provide a suitable complete electrical circuit for the motor. Non-conducting members are positioned between adjacent ones of the electrically separated contact elements.

Title: Subscription-based billing methods and systems for shared network modem pools
Inventor: CHIEN HERMAN
IPC: H04L12/66
Filed: 2000-11-01
Abstract: Methods of billing telephone calls in networks that utilize shared modem pools. A request from a user of the network is received along with user identifying data. The user identifying data is correlated with records in a database of user identifying data and if a match is found, the call is passed through the network. The user has then been authenticated as a valid user of the network and can be billed accordingly, even though a random modem in the modem pool was used to place the call. This allows the user to be billed for the call so that the owner of the modem pool is not left financially responsible for the long-distance and/or other toll charges incurred by the user in making the call. The methods also ensure that the modem pool owners can bill for all calls, thereby enhancing the network's revenue stream.

Title: Instruction fetch unit in a microprocessor
Inventor: KONIGSBURG BRIAN R
IPC: G06F9/30
Filed: 2001-01-23
Abstract: A microprocessor, data processing system, and an associated method of executing microprocessor instructions and generating instruction fetch addresses are disclosed. The microprocessor includes an instruction fetch unit comprising and instruction fetch address register (IFAR) and an instruction processing unit (IPU). The IFAR is configured to provide an address to an instruction cache. The IPU is suitable for receiving a set of instructions from the instruction cache and for generating an instruction fetch address upon determining from the set of instructions that the program execution flow requires redirection. The IPU is adapted to determine that the program flow requires redirection if the number of branch instructions in the set of instructions for which branch instruction information must be recorded exceeds the capacity of IPU to record the branch instruction information in a single cycle. The IPU may include an address generation unit suitable for generating a set of branch target addresses corresponding to the set of received instructions and a multiplexer configured to receive as inputs the set of branch target addresses. The output of the multiplexer is provided to the instruction address fetch register. The IPU may include an address incrementer suitable for generating a next instruction address corresponding to the next sequential instruction address following the instruction address corresponding to the received set of addresses. In this embodiment, the next instruction address comprises an input to the multiplexer. The IPU may further include selector logic adapted to select the next instruction address as the output of the multiplexer if the number of branch instructions in the set of instructions for which branch instruction information must be recorded exceeds the capacity of IPU to record the branch instruction information in a single cycle. The selector logic is adapted to select as the output of the multiplexer the branch target address of the first instruction predicted to be taken if the number of branch instructions in the set of instructions for which branch instruction information must be recorded does not exceed the capacity of IPU to record the branch instruction information in a single cycle.
