ERAVANT
In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis.[1][2] When graphed in three dimensions (see graph) this radiation pattern is often described as doughnut-shaped. Note that this is different from an isotropic antenna, which radiates equal power in all directions, having a spherical radiation pattern. Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so little radio energy is aimed into the sky or down toward the earth and wasted. Omnidirectional antennas are widely used for radio broadcasting antennas, and in mobile devices that use radio such as cell phones, FM radios, walkie-talkies, wireless computer networks, cordless phones, GPS, as well as for base stations that communicate with mobile radios, such as police and taxi dispatchers and aircraft communications.

Objective Interface Systems
Objective Interface Systems (OIS) was founded in 1989 with the goal of providing products that enable customers to build vastly superior information systems and technologies.OIS's products allow the system and software engineers to assemble flexible systems with incredibly agile communications infrastructures.The products enable real-time, embedded, and high-performance systems based on standards-based communications infrastructures on a wide variety of deployment environments. These tools result in systems that are more flexible, reliable, predictable, and correct than what was previously possible. OIS products are the Heart of Communications.OIS provides the most reliable products available. Every OIS software engineer is trained in DO-178B safety-critical engineering processes, Software Considerations in Airborne Systems and Equipment Certification. This well-established process standard arguably provides the best method for achieving high-correctness in engineering processes. Every line of OIS product source code goes through an arduous multi-person peer review and requirements traceability analysis. Critical sections get even more scrutiny. Every product build goes through automated regression testing and verification by a group independent of the developers.

Acopian Technical Company
Extremely high overall reliability results from connecting two power sources so that one will continue to provide power to their load even if the other becomes inoperative. Redundancy may be restored by replacing or repairing the inoperative source while the system remains in operation. A redundant power system should be used whenever the highest attainable reliability is essential, as in communications, computer systems (data storage in particular), process controls, utility and municipal systems, and security/safety systems.

TOPTEST GmbH
Development of a 12-way test and programming adapter from Toptest for ?? The Dash ?? from Bragi, a wireless, intelligent earphone with communication and sensor technology. With the first version of the test adapter, only a purely sequential testing was possible due to the interdependencies of the tests. In version 3.0, the now autonomous tests were brought into a parallel TestStand sequence. In addition, individual sockets were prioritized in order to optimally use the hardware resources. This resulted in a time advantage of 80% compared to the initial situation.
