Abstract: An outboard engine system includes a case member which is disposed below an engine body and integrally provided with an oil pan opening upwards, and a passage wall extending vertically to define an exhaust gas passage through which an exhaust gas flows. A portion of an outer wall of the case member is formed by the passage wall, and a recess is provided in the outer wall of the case member with a portion of the passage wall facing the recess. The recess is covered with a plate member fixed to the outer wall of the case member, and a cooling water passage, through which cooling water flows, is defined between the plate member and the recess. Thus, the passage wall integral with the oil pan is cooled effectively, while avoiding increases in size and weight.

Abstract: The invention relates to methods, apparatus, and software for designing and building virtual environments for playing computer games. A map builder is used to construct one or more two-dimensional maps comprised of tiles selected from a set of tiles, the map or maps representing the virtual environment for the computer game. Data describing the map is then combined with tile data providing 3D geometry to create the virtual environment. The tile data preferably also includes non-visible game-related data such as collision and navigation data, which is also combined to provide game data for the game's virtual environment. The tiles include interfaces for connecting one tile to another and, in a preferred embodiment, two versions of the interface geometry are provided for each tile, one with the interface open, the other with the interface closed.

Title: Method for limiting the number of simultaneous call forwarding attempts in a cellular communication system
Inventor: BOYLE PATRICK JOSEPH
IPC: H04M3/00
Filed: 2001-07-04
Granted: 2005-01-11
Abstract: The present invention provides a method for limiting the number of simultaneous call forwarding attempts for a mobile unit. A call is made for a mobile unit. The call request is sent to the MSC associated with the mobile unit.      When the mobile unit is not currently active at the MSC, the MSC sends a location request to an SCP. The SCP responds with a return message that includes a temporary location directory number (TLDN) and an indicator. The MSC checks the current number of simultaneous call forwarding attempts being made for the mobile unit. If the current number of simultaneous call forwarding attempts exceeds a threshold, the MSC does not forward the call. If the number of simultaneous attempts does not exceed a threshold, the MSC forwards the call to the mobile unit by sending it to the TLDN.

Abstract: A method of monitoring variations is carried out within an electrical energy meter containing means therein for metering a quantity of electrical energy generated by a supplier and transferred via a power supply line to a load. The method includes a first step of sensing a line voltage transferred via the power supply line to the load during the energy measurement time interval. The method also includes the step of detecting a variation in a magnitude of the sensed line voltage relative to an acceptable voltage level, wherein the variation exceeds a first variation threshold. The method then includes the step of capturing a first waveform of the sensed line voltage corresponding to the time when the variation is detected. Finally, the method includes the steps of detecting a subsequent reduction in the variation of the magnitude of the sensed line voltage such that the variation is equal to or less than the first variation threshold and capturing a second waveform of the sensed line voltage corresponding to the time when the subsequent reduction in the variation is detected.

IPC: B23K26/38
Filed: 2002-02-13
Granted: 2006-04-04
Abstract: On a wafer, patterns of arrayed waveguide gratings are formed. Each arrayed waveguide grating has an arcuate shape obtained by arranging two curved-line portions convexed in the same direction at a predetermined spacing and connecting respective end portions thereof with two mutually parallel straight lines. These arrayed waveguide gratings are cut out along straight cutting paths and curved cutting paths in which two arcuate portions of the same shape are arranged side by side in a lateral direction. Thus, a larger number of chips can be produced as compared with a case where each array waveguide grating is cut out in a rectangular shape. Ultrasonic machining techniques or sandblast machining techniques are suitable for the cutting operation.

Abstract: A system and method for cancelling an echo signal. An input waveform is provided to an acoustic processor, and a determination is made whether the input waveform includes information representative of an echo signal. If the input waveform includes information representative of an echo signal, an output waveform is formed by attenuating a residual waveform with the acoustic processor. The residual waveform is attenuated by an attenuation factor that gradually changes from an initial attenuation value to a final attenuation value during the attenuation step. A system and method for adjusting an acoustic signal from a muted state to an unmuted state by varying an attenuation factor applied to an acoustic signal by an acoustic processor. The acoustic signal is provided to an acoustic processor. An output waveform is formed from the acoustic processor by adjusting the attenuation factor from a muted state to a first attenuation value associated with the non-muted state. After the attenuation factor is adjusted to the first attenuation value, the output waveform is formed by gradually changing the attenuation factor from the first attenuation value to a second attenuation value. The input waveform is attenuated by a smaller amount when the second attenuation value is applied to the acoustic signal than when the first attenuation value is applied to the acoustic signal.
