Abstract: A method for synchronizing a first database including first data records with a second database including second data records. The method includes starting a synchronization session with an electronic device on which the second database resides, requesting the first data records from the first database, temporarily disconnecting the synchronization session while awaiting receipt of the first data records, receiving the first data records, and restarting and completing the synchronization session.

Abstract: An adjustable cushioning system, for use in a carrying case or the like, adapted to be re-sized internally to match the size and shape of its contents. Shock-absorbent spacers are stacked against the walls of the case or bag to adjust the internal dimensions of the case or bag as desired.
Abstract: A method for synchronizing databases at a portable electronic device with corresponding databases at a second electronic device, the method including determining which one of the databases at the portable electronic device is to be synchronized based on a directed acyclic graph representing database dependencies, and synchronizing the one of the databases at the portable electronic device with a corresponding one of the databases at the second electronic device.
Abstract: For use in a communication system having at least one enterprise server for facilitating communications and delivery of services to users of handheld mobile communication devices and an administrative program for managing the enterprise server, the improvement comprising an automated script for testing operation of the administration software by automatically executing operations and verifying results of these operations.
Abstract: A system and method for maintaining a persistent connection is provided. In an embodiment, a system includes a client that connects to a web-server via a physical link that is bandwidth-constrained. The physical link also includes at least one network address translation (“NAT”) router that is configured to terminate idle connections between the client and the web-server. The client is configured to send keep-alive packets to the web-server in order to reduce the likelihood of the NAT router terminating the connection. The keep-alive packets are sent on a variable basis that is intended to reduce bandwidth consumption while ensuring that the NAT router does not deem the connection idle and terminate the connection.
Abstract: A novel apparatus and method for changing the behavior of an electronic device is provided. In an embodiment, an electronic device includes the functionality of a cellular phone, a voice mail system and a calendar application. The device is configured to use the calendar application to determine whether to direct a phone call to the user or whether to instantly direct the call to voice mail.
Abstract: A fault detection apparatus for surface mount packages is provided. The apparatus can include a retainer for releasably securing a circuit board such as a printed circuit board having an electrical component mounted thereon via a ball grid array surface mount package. When mounted within the apparatus, a test signal is applied to the electrical component. The apparatus includes a mechanical actuator, such as a solenoid, for applying a reciprocating force to the circuit board. The reciprocating force can disturb a defect in the ball grid array manifesting as a mechanically unreliable connection at one of the balls where an electrically intermittent connection is occurring. By disturbing the mechanically unreliable connection, the electrically intermittent connection can be caused to fail altogether and thereby reveal the defect as a test signal is carried through the printed circuit board.
Abstract: A shared light pipe is set forth for transmitting light generated by a message waiting LED in a mobile communication device, in one direction, and transmitting ambient or surrounding light, in an opposite direction, to a light sensor for controlling a display backlight of the device. The light pipe includes an elongated first portion having a first end for receiving and transmitting light and external surfaces for reflecting light there through via total internal reflection (TIR), a second portion coextensive with the first portion for outputting light received at the first end and reflected through the first portion, and a second branch coextensive with the first portion for receiving and transmitting light for output at the first end.
Abstract: A method for memory management in an electronic device includes receiving partial content data records at the electronic device, storing the partial content data records in a memory of the electronic device, receiving a full content data record corresponding to one of the partial content data records, determining whether or not sufficient memory is available in the memory of the electronic device to store the full content data record and, if so, writing the full content data record over the corresponding partial content data record stored in the memory; and repeating the receiving and determining until either: full content data records corresponding to each of the partial content data records are received; or a low memory condition is determined in the memory. The partial content data records include key fields of data sufficient for uniquely identifying corresponding full content data records at a second electronic device.
Abstract: A typing keyboard is provided for minimizing non-productive hand movements. The keyboard comprises a plurality of keys for entering alphanumeric text, the keys being positioned according to a conventional keyboard layout, and at least one modifier key for assigning commonly-used keyboard functions to predetermined ones of the keys positioned near a normal resting position of a user's typing fingers.
Abstract: The present invention provides a novel device and method for controlling the display of electronic information. The device can be based on the computing environment of an enhanced personal digital assistant with cellular telephone and electronic message capabilities. The device is operable to present, on its display, user customizable information, such as wallpaper, in conjunction with non-customizable information, such as icons. The device is also operable to perform a transformation such that the user customizable information and non-customizable information are more legible than if no transformation had occurred.
