Title: Method and apparatus for identifying type of call
Inventor: WU WOODY
IPC: H04M3/02
Filed: 1997-10-22
Abstract: A local switch includes circuitry for determining whether a called party is a subscriber of a call type delivery service when a call is being placed to the called party. The local switch also includes circuitry to generate a message to prompt the calling party to identify whether the call is urgent, normal, or telemarketing.

Patent CA-2278794-A1 (CA)
Inventor: SKENE JEREMY
IPC: H04M3/42
Filed: 1998-11-18
Abstract: A callback system detector (300) is connected between a toll trunk (200) and a local switched telephone network (100) for detecting and discouraging operation of a toll callback system wherein incoming calls on the toll trunk line are employed as a gateway for a user of the switched telephone network (100) to place calls within a remote telephone network and thus avoid tariffs charged by the local network (100) for outgoing calls to the remote network.  The callback system detector is configured to determine the presence, within an incoming call on the toll trunk (200), of a condition indicative of operation of such a callback system. Such a condition may be defined as incoming dial or ringing tones on the toll trunk, or as outgoing dual-tone multi-frequency (DTMF) tones on the toll trunk. In order to allow such tones to be transmitted in the normal course of a call that may legitimately employ such tones, operation of the callback detector may advantageously be limited to a predetermined time period defining an initial call interval. The callback detector (300) may be configured to disrupt communication within the call upon detection of the condition, or further may be configured to cause disconnection of the call or assessment of a billing charge to the local recipient of the call.

Inventor: FLICK ROBERT R
IPC: F23D14/84
Filed: 1999-11-24
Abstract: A gas heater includes a gas burner system having a gas burner engulfed by a cullet that diffuses the gas flowing from the burner. The cullet is preferably broken tempered glass and is otherwise chosen from among materials which are non-moisture absorbent. The cullet and burner may be contained within a burner box having a propagation plate covering with slots to specifically locate the flame to avoid contact with an artificial log set for safe, efficient operation. The burner system immediately produces a dancing, multi-colored, natural-looking flame while eliminating instance of pop and flash-back. The cullet insulates the burner and therefore prolongs its life, as well as allows a relatively maintenance free, clean burning and cost effective burner system compatible with different types of gases.

Patent CA-2298981-A1 (CA)
Inventor: FAYYAZ NADER
IPC: H03B5/12
Filed: 2000-02-18
Abstract: A fully integrated resonant type voltage controlled oscillator (VCO) circuit with one-octave tuning range for the generation of frequency signals is disclosed.  The circuit comprises a current source to supply a bias current to a pair of NPN bipolar junction transistors (BJT) connected across a low-Q inductor. The forward bias base-emitter capacitance inherent to the BJT provides the capacitive component for the inductor-capacitor circuit, such that the circuit does not require the use of a varactor diode or any capacitor elements. Because the VCO circuit is tuned by current and not voltage, a wide tuning range is achieved with low voltages such that the VCO can oscillate at frequencies between 2.7GHz and 6.2GHz.

Title: System for multiple voice lines with data over a single subscriber loop
Inventor: BROWN RANDALL L
IPC: H04L12/16
Filed: 2000-03-27
Abstract: A system that provides additional voice lines with data over a single two-wire subscriber loop. At the subscriber premise, one or more telephone instruments and data devices are connected to a digital modem into either a voice or a data interface. Analog voice signals are PCM sampled then packetized, and voice and data packets are transmitted to a CO modem over the subscriber loop. The CO modem depacketizes the voice packets into PCM format and transmits PCM voice information to a CO switch over a standard digital trunk interface. Data packets are routed to a data network.  Voice packets are given transmission priority over data packets to ensures that voice is transported in the presence of data with low latency.

Title: Automated validation and verification of computer software
Inventor: GOOSSEN EMRAY R
IPC: G06F11/28
Filed: 1998-09-24
Abstract: A method and apparatus for automating validation and verification of computer software confirms that during a test execution of the software, all lines of code are executed and all branches in the software are taken or not taken at least once. The computer software to be tested is compiled and a link map is generated. After compilation of the code, it is run in a test fixture to test all the design functions. During this test execution, a monitoring process is performed which documents which lines of code have been executed and when and when not certain branches were taken. Two maps are generated which indicate what instruction branches were taken and were not taken. A comparison is then made between the link map originally generated and the two branch maps generated to determine what lines of code were executed, whether each branch was taken at least once, and whether a branch was not taken.
