| 20080209242 | MODEM CARD CONFIGURED TO COMPENSATE FOR POWER SUPPLY - A modem card includes a connector configured to be detachably connected to a computer. The card also includes electronics configured to be powered by a power supply located in the computer and to transmit wireless signals to a communications network at a transmit power. The electronics are configured to vary the transmit power such that the transmit power does not exceed a maximum transmit power. Increases in the transmit power cause a drop in the voltage of the power. The electronics are also configured to determine an adjusted maximum transmit power. The adjusted maximum transmit power is a transmit power at which the signals can be transmitted to the communications system without the voltage dropping below a shut-down voltage. The electronics are also configured to reduce the value of the maximum transmit power to a value that that is less than or equal to the value for the adjusted maximum transmit power. | 08-28-2008 |
| 20080231520 | MODEM CARD WITH THREE-DIMENSIONAL ANTENNA ARRANGEMENT - A modem card is configured to provide communication between a computer and a communications system. The modem card includes a case holding electronics. A corner extends along a top side of the case. An antenna body is connected to the case such that the antenna body bends around the corner of the case. An antenna is positioned in the antenna body such that the antenna bends around the corner of the case. The antenna is in electrical communication with the electronics in the case. | 09-25-2008 |
| 20080298447 | DETERMINING WIRELESS DATA RATES CAPABILITY FOR PACKET DATA COMMUNICATIONS - A wireless device, system, and method that determines data rate capability for communicating packet data is described. The wireless device comprises a RF component, a controller, and a means for enabling communications. The RF component is configured to communicate a plurality of packet data at a first data rate capability and a second data rate capability, in which the second data rate is faster than the first data rate. The controller is communicatively coupled to RF component, and the controller is configured to monitor a physical layer data field value, a forward traffic channel data field value, and a reverse traffic channel data field value. The physical layer data field value is associated with the physical transmission of packets from the RF component. The forward traffic channel data field value is associated with forward channel communications, and the reverse traffic channel data field value that is associated with reverse channel communications. The means for enabling communications at the second data rate capability occurs when the physical layer data field value, the forward traffic channel data field value, and the reverse traffic channel data field value indicate that communications are supported for the second data rate capability. | 12-04-2008 |
| 20090270080 | EMERGENCY RINGING FACILITY FOR MOBILE PHONES - Systems and methods for an emergency ringing facility able to remotely override a silent mode of a wireless communication device are disclosed. The systems comprise profile-management applications residing on wireless devices and allowing one user of a wireless device to override a silent mode of a remote wireless device. The profile management application executed on the wireless device queries whether the silent mode of the remote wireless device can be overridden, and if so, communicates with a profile-management application executed on the remote device and overrides the silent mode of that device. In an alternative embodiment, a silent mode of a wireless device can be overridden by a profile management server. A profile-management application is executed on a profile-management server communicating with a profile-management application executed on a wireless device and requests the overriding of the silent mode of a remote wireless device. | 10-29-2009 |
| 20100273536 | METHOD AND APPARATUS FOR POWERING A WIRELESS PERIPHERAL - An apparatus for powering a wireless peripheral includes a controller and a power management circuit. The controller is configured to determine the strength of wireless signals received by the peripheral. The power management circuit selectively powers the peripheral with either an external power source or a combination of the external power source and an internal power source included in the wireless peripheral. If the wireless signal strength is weak, the power management circuit uses both the internal an external sources to power the peripheral. This allows the wireless peripheral to boost its transmit power, even though its power requirement may exceed that available from the external source. If the wireless signal strength is strong, the power management circuit uses only the external source to power the peripheral. When this occurs the internal power source may also be simultaneously charged by the external power source. | 10-28-2010 |
