Title: System, method and article of manufacture for product return of software and other information
Inventor: HURLEY JOHN C
IPC: G06Q20/12
Filed: 1998-06-18
Abstract: Software allows a vendor to grant full access to demonstration software that has been downloaded to a user's computer as well as return the product for credit. To obtain full access, the user obtains an access code from the vendor, which unlocks the software at (200). To effect a product return, the user would call the customer service department of the manufacturer and talk to a telemarketer or carry out a return session with the vendor's return server at (202). The user reads a serial number to the telemarketer at (204) or supplies the serial number to the return server. The return server uses this number to generate a return authorization code, which is then supplied to the user at (208). When this code is accepted, the user is shown a confirmation code at (210). The user supplies this code to the vendor for comparison with the code generated on the vendor's system at (212). If the confirmation codes match, the user has correctly entered the return authorization code, and the vendor can issue a credit at (214). The software is then only usable in its demonstration form, or if the demo period is expired, is disabled completely.

Title: Method and apparatus for transmitting signals in a communication system
Inventor: ROZANSKI WALTER J JR
IPC: H04W72/04
Filed: 1998-07-14
Abstract: Different orthogonal codes (W x, W y) are used to spread common pilot channels (Pilot A) intended for transmission to a particular mobile station (106) within a coverage area (sector A) to implement forward link transmit diversity. By implementing separate, different orthogonal codes (W x, W y) for each pilot channel (Pilot A), the pilot signals transmitted via antennas (218, 222) to a common coverage area (sector A) are orthogonal to one another and thus do not degrade system performance. Additionally, the use of different orthogonal codes (W x, W y) for each pilot channel (Pilot A) allows the mobile station (106) to discern which pilot channel spread with a different orthogonal code includes corresponding traffic channel (TCH) information. This allows forward link transmit diversity to be enabled/disabled based on conditions associated with the environment, the communications channel, etc. without a complete loss of information as seen by the mobile station (106).

Inventor: DALLAS TIM
IPC: E21B47/01
Filed: 2000-03-08
Abstract: This disclosure describes a blended buoyancy oil well survey instrument. An oil well survey instrument in a closed cylindrical housing having a specific gravity greater than the drilling mud in which it is used is modified in buoyancy by attaching one of several identical elongate cylindrical hollow containers or cylinders to it. They are filled with light material. They are made sufficiently strong that they do not collapse at working pressures. The cylinders are provided with upper end and lower end threaded stub shafts and mating receptacles to thread together thereby providing a modified buoyant system. The method is concerned with adjustment of the buoyancy so that the rate of fall is modified; in conjunction with mud flow velocity in the drill string, the buoyant descent of the instrument is controlled to about 100 or 200 feet per minute.

Title: Mobile terminal and method of preventing loss of information for the mobile terminal
Inventor: ORSIC MILO
IPC: H04W36/18
Filed: 2000-04-10
Abstract: A mobile terminal (MT) and a method of preventing loss of information for a MT using a simple link-layer connection with new and old BSs. As the MT roams through the global Internet, the MT establishes a link-layer connection with a BS and obtains an IP address identifying this connection. When the MT establishes a new link-layer connection with a new BS and obtains a new IP address, the MT  maintains the link-layer connection to the previously visited (old) BS and the old IP  address for a predetermined time period. By maintaining two IP addresses and the link-layer connections to the new and old BSs at the same time, the MT can receive any IP traffic directed to the old IP address for a certain period of time and the IP  traffic directed to the new IP address. The method prevents loss of information directed to the old IP address of the MT as the MT roams in the global Internet.

Patent CA-2307172-A1 (CA)
Inventor: MACBETH BRUCE F
IPC: G01R31/12
Filed: 2000-04-27
Abstract: Briefly stated, and in accordance with a presently preferred embodiment of the invention, an arc fault detecting circuit using a pulse width modulation, or PWM, technique is used to sense series or parallel arc faults. When arc faults occur, typically an arc step in current is followed by broad band arc noise which is caused by the random fluctuations in arc column resistance. In this invention, a logic signal is created which has a duration or width that corresponds to the time interval during which the broad band arc noise generated by the arc is present. Typically an arc fault randomly starts, generates broad band arc noise, and then extinguishes as the next current zero cross of the AC load current is approached. The random start causes PWM of the logic pulse whenever the start of the arc randomly moves with respect to the current zero cross. An arc fault that randomly starts, and then randomly stops, will also cause PWM with respect to the zero cross. The PWM logic pulse is coupled to the input of a microprocessor which measures and stores the length of the present PWM pulse under measurement, and compares that pulse to the pulse length of the last stored PWM pulse, and increments a counter if the difference in pulse length is greater than a predetermined amount. When the counter number is greater than or equal to a predetermined number held in the microprocessor memory, an output signal is sent to a controller which activates the circuit interrupter. Another input to the microprocessor, corresponding to the magnitude of the arc current, is used to adjust the predetermined number value down or up depending on the intensity of the arc fault for faster or slower interrupts respectively.

IPC: H04L47/2416
Filed: 1997-10-24
Abstract: In congestion control in a digital communications network such as the Internet or corporate "Intranets", and especially in real-tine transmissions in such networks, perfect reliability may not be required. For increased likelihood that data arrive on time, an estimate is used of the bandwidth which is available from a sender to a receiver. The estimate is increased or decreased, by the sender, depending on monitoring of acknowledgemnts from the receiver.  The technique coexists well with protocols based on TCP (Transmission Control Protocol), such as FTP (File Transfer Protocol) and HTTP (Hyper Text Transfer Protocol), by sharing the available bandwidth equally.

Abstract: A system and methodology for building highly scalable Network Management Systems (NMS)s for the management of large voice and data networks is provided. The NMS of the present invention is designed to manage a plurality of network elements communicating through network controlled links. The elements are combined into management groups of no more than n elements. A first functional subsystem controls and manages the communication functions associated with a first group of elements. Each function or process inside the subsystem is guaranteed to communicate with only one instance of every other type of process or function. As additional network elements are added to the system, additional management groups are also added, one functional subsystem for every management. group of elements. The plurality of other functional subsystems are substantially the same as the fust functional subsystem. Limiting the management process to intra-subgroup communications greatly simplifies expansion of the system. When a total of m management groups exist, at least (m - 1) functional subsystems are replicated from the first NMS subsystem. Thus, the network is scaled up by using size-limited subsystems.
