Abstract:
A selective call device for receiving a signal having an address portion and a message portion, the message portion having sub-messages, includes a receiver, a message memory for storing sub-messages, and address correlator and a decoder for determining whether the signal is directed to the selective call device and whether the signal includes a Delete Command having parameters that identify a portion of a sub-message, or an Insert Command having an additional portion and parameters that identify a location in a sub-message. In response to a Delete Command, the selective call device decreases size of a sub-message (801) stored in the message memory by erasing the identified portion of the sub-message (802). In response to an Insert Command, the selective call device increases size of a sub-message (802) stored in message memory by adding the additional portion to the sub-message at the identified location (803).
Abstract:
A method and apparatus provides for motion activated control of an electronic device. The method activates a function, such as a backlight feature, of an electronic device, by storing at least one motion sequence and a function corresponding to each motion sequence. Motion of the electronic device is monitored, and when it is determined that the monitored motion corresponds to a motion sequence, the stored function that corresponds to the stored motion sequence is activated. The apparatus has a motion transducer that senses motion of the electronic device, and a device controller in communication with the motion transducer that activates the corresponding function when a motion processor determines that the stored motion sequence has been sensed by the motion transducer.

Abstract:
An access point ( 102 ) conveys ( 202 ) to communication units ( 104 ) of a plurality of multicast groups, a first indication that the access point supports a method for sending a multicast message. The access point receives ( 204 ) a multicast message directed to a receiving one of the plurality of multicast groups, and determines ( 206 ) that the communication units belonging to the receiving one of the plurality of multicast groups also support the method. The access point signals ( 208 ) a second indication to selectively awaken the communication units belonging to the receiving one of the plurality of multicast groups, and transmits ( 210 ) the multicast message to the receiving one of the plurality of multicast groups in a manner that allows ( 212 ) at least one communication unit not belonging to the receiving one of the plurality of multicast groups to remain asleep during the transmitting.
Abstract:
A method and apparatus for passing a message (310) at a gateway (304) between a first network (302) and second network (110) (Fig. 3). A message (310) is received from the first network (302). Header information is added to the message indicative of an address associated with the gateway (310). Header information is added to the message indicative of an address associated with the first network (312). The message is forwarded from the gateway to the second network (110).
