Abstract: A transceiver is configured to: pair with a mobile device; and transmit a predetermined signal from an antenna to the mobile device. A zone module is configured to: receive a signal from the mobile device in response to the predetermined signal; and based on the signal, select a zone within which the mobile device is present from a group consisting of: a first zone that is defined by a first radius from the antenna; a second zone that excludes the first zone and that is defined by a second radius from the antenna, where the second radius is greater than the first radius; and a third zone that is radially outward of the second zone and that excludes the first and second zones.

Abstract: A filtration system comprising a filter cassette having integrated ultrasonic transducers incorporated therein, and a method for using the same. The integrated system of filters and transducers can be hardened for use in hazardous environments, and is particularly suitable for the implementation of sonication in cross flow filtration processes further integrated with a manufacturing process. The system provides cost savings both in terms of less equipment and space for cleaning processes on the manufacturing floor.

Abstract: A coating application system includes a coating applicator having an outlet through which a stream of a liquid coating is delivered, a substrate which receives the stream of liquid coating, and a vacuum system which applies a vacuum to the liquid coating.

Abstract: A musical instrument having a general body outline similar to that of a saxaphone. A front key panel having a plurality of keys mounted thereon is located for easy fingering access to the keys which are in the same general location as the fingering keys on a saxaphone. A rear control panel is provided for mounting instrument voice characteristic and special effects controls. A mouthpiece is provided for engagement by a player's mouth and a pressure transducer is carried in the mouthpiece for communication with the player's breath pressure and for producing a pressure signal corresponding thereto. The pressure signal is connected to a pressure attack circuit for producing a pressure attack signal. Finger pressure applied to predetermined combinations of keys provides predetermined combinations of key pulses for connection to a key decoder. The key decoder produces a binary output corresponding to the predetermined combinations of key pulses which ranges from zero to 1111.
