Abstract: Processes and systems (300) for reducing pessimism in cross talk noise aware static timing analysis and thus resulting false path failures use either or both of effective delta delay noise (307) and path based delay noise (311) analysis. Effective delta delay determines an impact (312, 314, 316) on victim timing of an action by aggressors that occur during a region (209, 319, 321) where victim and aggressor timing windows overlap and determines an effective delta delay 317 corresponding to any portion 316 of the impact on victim timing that extends beyond the victim timing window. The effective delta delay is used to adjust the victim timing window. Path based delta delay determines an uncertainty (627, 637) in a switching time corresponding to a particular path for a victim resulting from an action (switching) by aggressors that occurs at the switching time 607, 613, i.e. during a switching time window (a2 to a2+u1) (613, 625) when uncertainty is included.

Abstract: Channelizing an applied current and applying a voltage to the channelized current enables switching of the applied current. According to the present invention, an applied current enters through a signal input carrier (12) and is channelized by a plurality of lateral potential wells created by a plurality of polysilicon fingers gates (14). A first voltage is applied to a first set of the plurality of polysilicon finger gates (32) and a second differential voltage is applied to a second set of the plurality of polysilicon finger gates (34), which results in a differential current flow among the lateral potential wells beneath the first and second sets of polysilicon fingers (32, 34), respectively. The differential current then flows to first and second signal output carriers (40, 42).

A plurality of data lines supplies image data to the display panel (126). The data lines include data lines for supplying red image data, green image data, and blue image data. Masking gates (118) are provided between a video buffer (116) and the display controller (124). A method of reducing power consumption includes masking selected ones of the data lines at predetermined times. The masking reduces the pixel depth of the image data. Thus, the pixel depth is reduced without re-encoding the source video data. Reducing the number of state transitions in the video data path reduces power consumption, thus longer battery life.

According to the present invention, a connection request, including network connectivity requirements, is communicated from the terminal device (114) to a first mobile station (116).

A determination based in part or in whole on the network connectivity requirements is then made at one of the first and second mobile stations (116–119) which station can provide a most appropriate wireless network connection. A network connection is then established through one of the first and second mobile stations (116–119) based on the determination of which of the first and second mobile stations (116–119) can provide the most appropriate wireless network connection.

The server stores (304) the group message, and transmits (316) the group message to each recipient of the pre-defined plurality of recipients whenever the recipient is actively coupled to the wireless communication system. The server indicates (318) thereafter to the originator that the recipient has received the group message.

Abstract: A communication apparatus includes a communication device (130) and an activity monitoring device (120). The communication device (130) includes an alert device (275) for notifying a user (110) of an incoming call. The communication device (130) further includes a controller (210) for selecting a mode of the alert device (275). The controller (210) judges, based on data from the activity monitoring device (120), whether the user can be disturbed, and, if the user (110) can be disturbed, the controller (210) selects an audible mode of the alert device (275). If the controller (210) determines that the user (110) cannot be disturbed, then the controller (210) selects a silent mode of the alert device (275). The activity monitoring device (120) produces data representing a biometric characteristic of the user (110), which is used by the controller (210) to judge whether the user (110) can be disturbed. A corresponding method (FIG. 6 and FIG. 7) selects an appropriate alert mode based user biometrics.
