Lowrance was founded in Tulsa, Oklahoma in 1957. In 2006, Simrad Yachting and Lowrance merged in a deal valued at $215 million, creating a new company named Navico. In 2006, Lowrance was purchased by Simrad Yachting for $215 million. [8] This merger went on to create Navico, now the largest leisure marine electronics manufacturer in the world. [9]
Most hydrographic operations use a 200 kHz transducer, which is suitable for inshore work up to 100 metres in depth. Deeper water requires a lower frequency transducer as the acoustic signal of lower frequencies is less susceptible to attenuation in the water column. Commonly used frequencies for deep water sounding are 33 kHz and 24 kHz.
A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. [1] Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).
The counter-countermeasure was a torpedo with active sonar – a transducer was added to the torpedo nose, and the microphones were listening for its reflected periodic tone bursts. The transducers comprised identical rectangular crystal plates arranged to diamond-shaped areas in staggered rows.
HTTP Live Streaming (also known as HLS) is an HTTP-based adaptive bitrate streaming communications protocol developed by Apple Inc. and released in 2009. Support for the protocol is widespread in media players, web browsers, mobile devices, and streaming media servers.
A piezoelectric transducer can be modeled as a voltage source with a filter. The voltage V at the source is directly proportional to the applied force, pressure, or strain. [ 11 ] The output signal is related to this mechanical force as if it had passed through the filter, which gives the transducer a very high and frequency-dependent output ...
A quick release and pressure release mechanism is fitted on ships so that the canister or pump automatically inflates the lifeboat, and the lifeboat breaks free of the sinking vessel. Commercial aircraft are also required to carry auto-inflating liferafts in case of an emergency water landing; offshore oil platforms also have liferafts.
If You Want to Walk on Water, You've Got to Get Out of the Boat (also simply referred to as If You Want To Walk on Water) is a 2001 book written by John Ortberg that uses the New Testament account of Jesus walking on water as a conceptual framework for discussing leaps of faith and encouraging readers to make them. [1] It became a bestseller. [2]
