Patent number: 7187937Abstract: A paging transceiver and method for selectively paging provides a page to a paging transceiver but does not automatically provide an associated message. The paging transceiver receives the page and alerts the user that a message is waiting and preferably provides a short description of the message.

The user can therefore place the paging transceiver in a location where it can easily receive and reply to the message. The paging system conserves air time and the paging transceiver conserves memory by not automatically receiving the associated messages. The user can determine the time at which the paging transceiver receives transmissions, such as during off-peak hours. The messages stored by the systems and delivered to the paging transceiver may be of different types, such as voice, text, audio, or even video.Type: GrantFiled: March 17, 2005Date of Patent: March 6, 2007Assignees: Thompson Investment Group LLCInventor: Richard J.

Patent number: 7187958Abstract: A folding mobile communications apparatus comprises an upper unit 200, a lower unit 100, and a hinge 300 for connecting the units as rotatable in an open-and-close state. On a main surface 201a of the upper unit 200, a first speaker 203 is provided at one end of the unit, and a second speaker 230 having at least the function of a receiver is provided near the hinge 300. On the main surface 101a of the lower unit 100, a microphone 103 is provided at an end opposite the hinge 300. A control unit 117 controls the first speaker 203, the second speaker 230, and the microphone 103 such that any two of them can function as a set of a receiver and a transmitter based on a relative position of the two units detected by an attitude detection unit 113.Type: GrantFiled: April 30, 2004Date of Patent: March 6, 2007Assignee: NEC CorporationInventors: Katsumi Nishijima, Akiko Shishido, Michio Nagai

Patent number: 7187959Abstract: A multiband element antenna (120) used in combination with a unique metal chassis design that enhances antenna performance and that enables the design of a compact and efficient antenna system. A cellular flip phone (100) that has a conductive chassis includes a flip up antenna (120) that pivots between an extended and a retracted position. The antenna (120) pivots at a point that is located on one edge of the top of the cell phone body (102). The conductive chassis of the flip cover (104) is grounded to the flip phone body (102) at a single point or single surface that is substantially opposite the antenna RF feed (122). Conductive surfaces of the cellular flip phone body (102) are grounded at a single point that is near the antenna RF feed point (122). This grounding arrangement has been found to control the flow of induced currents on the conductive portions of the flip cover (104) and body (102), thereby improving the performance of the device's antenna (120).Type: GrantFiled: November 25, 2003Date of Patent: March 6, 2007Assignee: Motorola, Inc.Inventors: Lorenzo A.
