Motorola, Inc. /moʊtɵˈroʊlə/ was a multinational telecommunications company based in Schaumburg, Illinois, United States . After having lost $4.3 billion from 2007 to 2009, the company was divided into two independent public companies, Motorola Mobility and Motorola Solutions on January 4, 2011. Motorola Solutions is generally considered to be the direct successor to Motorola, Inc., as the reorganization was structured with Motorola Mobility being spun off.Motorola designed and sold wireless network equipment such as cellular transmission base stations and signal amplifiers. Motorola's home and broadcast network products included set-top boxes, digital video recorders, and network equipment used to enable video broadcasting, computer telephony, and high-definition television. Its business and government customers consisted mainly of wireless voice and broadband systems , and, public safety communications systems like Astro and Dimetra. These businesses are now part of Motorola Solutions. Google sold Motorola Home to the Arris Group in 2012.Motorola's wireless telephone handset division was a pioneer in cellular telephones. Also known as the Personal Communication Sector prior to 2004, it pioneered the "mobile phone" with DynaTAC, "flip phone" with the MicroTAC as well as the "clam phone" with the StarTAC in the mid-1990s. It had staged a resurgence by the mid-2000s with the RAZR, but lost market share in the second half of that decade. Later it focused on smartphones using Google's open-source Android mobile operating system. The first phone to use the newest version of Google's open source OS, Android 2.0, was released on November 2, 2009 as the Motorola Droid . The handset division was later spun off into the independent Motorola Mobility. On May 22, 2012, Google CEO Larry Page announced that Google had closed on its deal to acquire Motorola Mobility. On January 29, 2014, Google CEO Larry Page announced that pending closure of the deal, Motorola Mobility would be acquired by Chinese technology company Lenovo for US$2.91 billion . On October 30, 2014, Lenovo finalized its purchase of Motorola Mobility from Google. Wikipedia.

In this paper, a physics-based model is proposed for a biomimetic robotic fish propelled by an ionic polymermetal composite (IPMC) actuator. Inspired by the biological fin structure, a passive plastic fin is further attached to the IPMC beam. The model incorporates both IPMC actuation dynamics and the hydrodynamics, and predicts the steady-state cruising speed of the robot under a given periodic actuation voltage. The interactions between the plastic fin and the IPMC actuator are also captured in the model. Experimental results have shown that the proposed model is able to predict the motion of robotic fish for different tail dimensions. Since most of the model parameters are expressed in terms of fundamental physical properties and geometric dimensions, the model is expected to be instrumental in optimal design of the robotic fish. © 2006 IEEE.

Three-dimensional video based on stereo and multiview video representations is currently being introduced to the home through various channels, including broadcast such as via cable, terrestrial and satellite transmission, streaming and download through the Internet, as well as on storage media such as Blu-ray discs. In order to deliver 3-D content to the consumer, different media system technologies have been standardized or are currently under development. The most important standards are MPEG-2 systems, which is used for digital broadcast and storage on Blu-ray discs, real-time transport protocol (RTP), which is used for real-time transmissions over the Internet, and the ISO base media file format, which can be used for progressive download in video-on-demand applications. In this paper, we give an overview of these three system layer approaches, where the main focus is on the multiview video coding (MVC) extension of H.264/AVC and the application of the system approaches to the delivery and storage of MVC. © 2010 IEEE.

A method and apparatus for a client to continue to receive updates from a server when a channel has been disconnected before the expiration of a heartbeat timer is disclosed. The method includes sending a heartbeat message from the client to the server wherein the heartbeat message is sent at the expiration of a timer having a first time interval that is less than the first timeout duration period of the server. The method includes detecting that the channel is disconnected before the expiration of the first time interval and then determining a second timeout duration period from detecting the channel is disconnected. After determining the second time out duration, the method includes resetting the first time interval to a second time interval for the sending of the heartbeat message wherein the second time interval being less than the second timeout duration period.

A technique for reducing a time delay between an application output at a subscriber station and uplink resource allocation for the subscriber station includes scheduling, between periodic uplink resource allocations, one or more probe uplink resource allocations for the subscriber station. Next, respective information in at least one of the one or more probe uplink resource allocations is received at an access point. Finally, subsequent periodic uplink resource allocations are scheduled based on at least one of the one or more probe uplink resource allocations.
