Handbook of software reliability engineering

A method of cross-platform messaging including receiving, by a messaging system, at least one initial message having a message format, an initial message layout and data indicative of at least one user associated with the at least one initial message, and before delivery to a destination communication device associated with the at least one user, converting, by the messaging system, an initial message into an adapted message, and facilitating, by the messaging system, delivery of the adapted message to the destination communication device. The adapted message is characterized by, at least, an adapted message layout, and the adapted message layout differs from the initial message layout in a characteristic associated with respective message layout such as number of media objects, a graphical image of a media object, a size of a placeholder related to a media object, and a location of a media object within a respective message layout.

Messaging system and method

A wireless power transmission system includes, a transmit antenna which in operation produces a wireless field, an amplifier coupled to the transmit antenna, a load sensing circuit coupled to the amplifier and a controller coupled to the load sensing circuit. A monitoring device has one or more sensors and a unique user ID. The one or more sensors acquire user information selected from of at least one of, a user's activities, behaviors and habit information. The monitoring device includes an ID circuitry. A communication interface receives information about the unique user ID when the load sensing circuit indicates the monitoring device is within the wireless field. The indication is created using at least a change in power consumption.

Telemetry system with tracking receiver devices

A wearable wireless portable device ("WWPD") includes cellular/WAN communications circuitry for establishing a direct connection to a telecommunication network and a low-power short range radio for establishing an indirect connection to the telecommunication network via the communications circuitry of the more feature-rich mobile device. The WWPD may be configured to deactivate its cellular/WAN communications circuitry (and other resource such as GPS) to communicate with a more feature-rich mobile device (e.g., a smartphone) via low-power short range communication technologies when it is in close proximity to the mobile device, and activate its cellular/WAN circuitry to provide cellular and/or network connectivity when it is not in close proximity to the mobile device. The WWPD does not require the bulky battery systems, which enables the WWPD to be packaged into a small and lightweight device, such as a wrist watch or pendant and enables longer battery life for the battery of the WWPD.

A survey of Gallium Nitride HEMT for RF and high power applications

A mobile device system and related method are disclosed by which the device is able to communicate wirelessly not only via a Wide Area Network (WAN) communication link but also via an alternate communication link such as a Wi-Fi communication link. In one embodiment, the method includes detecting an availability of an additional (alternate) communication link made possible via an access point (AP), determining whether one or more first criteria relating to one or both of the AP and the device have been met and, provided that the one or more first criteria are met, automatically launching a browser to communicate with one or both of the AP and a remote server. The method further includes determining based upon one or more interactions whether one or more second criteria have been met and, provided that the one or more second criteria are met, conducting communications via the additional communication link.

Method and system for facilitating wireless communication via alternate wireless pathway

The dynamic characteristics of wurtzite (Wz) phase and zincblende (Znb) phase GaN IMPATTs are reported at D-band and compared with Si and GaAs-based IMPATT devices at the same operating conditions and frequency of operation. It is shown that GaN-based IMPATTs are potential candidates for replacing traditional IMPATTs at high frequency of operation.

DC and high-frequency characteristics of GaN-based IMPATTs

Growth of wide bandgap material over narrow bandgap material, results into a two dimensional electron gas (2DEG) at the heterointerface due to the conduction band discontinuity. In this paper the 2DEG transport properties of AlGaN/GaN-based high electron mobility transistor (HEMT) is discussed and its effect on various characteristics such as 2DEG density, C-V characteristics and Sheet resistances for different mole fractions are presented. The obtained results are also compared with AlGaAs/GaAs-based HEMT for the same structural parameter as like AlGaN/GaN-based HEMT. The calculated results of electron sheet concentration as a function of the Al mole fraction are in excellent agreement with some experimental data available in the literature.

Characteristics study of 2DEG transport properties of AlGaN/GaN and AlGaAs/GaAs-based HEMT

A method and apparatus for handling messaging service message adaptation. An original message is received from an originating communication device, the original message based on a wireless communication message protocol, the original message being of a first message type. The message is modified according to preferences of a message recipient communication device to generate a second message of a second message type. The second message is sent to the message recipient communication device. A modification notification is sent to the originating communication device, the modification notification indicating that the original message was modified.

A generalized method of analysis for avalanche noise in mixed tunneling and avalanche transit time (MITATT) diode is reported. This method can be applied to MITATT diodes with arbitrary doping distribution and arbitrary material combinations. The method is capable of estimating the mean-square value of the noise voltage as well as the noise distribution due to individual space steps caused by the individual noise sources. The method has been applied to a variety of Si double-drift diode structures with different levels of tunneling currents. The results indicate some new and interesting features of noise for mixed-mode operation.
