摘要： A computer graphics system stores graphics data the represents one or more three dimensional objects. The objects are represented by one or more primitives each defined by a plurality of vertices. The graphics systems renders the objects to generate a two dimensional image for display. During the rendering operation, coordinates of vertices of said primitives are subjected to a perspective transformation. The present invention provides a method and apparatus that uses at least one look-up table for mapping a texture function to pixels covered by at least one of said primitives.

摘要： A portable intelligent shopping device which can be worn as a wristwatch or carried on a belt. It makes paying for purchases more secure. The device stores the wearer's private key and digital certificate. It can also store the public keys of various stores. When the wearer (shopper) buys something from a store, the store can request a payment of the appropriate amount from the wearer's watch. The authorization for payment of the amount specified by the request for payment may be transmitted using IR or RF. The watch can then display the amount and request the shopper to confirm the transaction by entering a PIN number by tapping on the touch screen or using the roller wheel. Once the correct PIN is entered, the watch can send a message to the store authorizing payment of the requested amount. The store can verify the message based on the shopper's encrypted certificate by decrypting it using the shopper's public key. The entire payment authorization signal can be encrypted by the shopper using the store's public key so that only the store can decrypt it with its private key.

摘要： The present invention is directed to a session initiation protocol (SIP) infrastructure containing various user devices and the use of this infrastructure to conduct media exchange sessions among the various user devices. Included in the user devices are wearable devices, for example pendants and wrist watches, that provide readily available and accessible devices for use in controlling the media exchange sessions. SIP permits the separation of the control aspects of a session from the actual media exchange aspects to facilitate the use of wearable devices having limited processing resources as control devices. The actual media exchange is directed to user devices suitable for sending, receiving and displaying the exchanged media.
摘要翻译：本发明涉及包含各种用户设备的会话发起协议（SIP）基础设施以及该基础设施在各种用户设备之间进行媒体交换会话的用途。用户设备中包括可穿戴设备，例如吊坠和腕表，其提供用于控制媒体交换会话的易于获得和可访问的设备。 SIP允许会话的控制方面与实际媒体交换方面分离，以便于使用具有有限处理资源的可穿戴设备作为控制设备。实际的媒体交换被引导到适于发送，接收和显示所交换的媒体的用户设备。
