Abstract: A method and an apparatus provides for an optimum musical stringed instrument dynamic force chain comprised of simultaneous axial witness point adjustment mechanism, adjustable truss rod, high energy resilient and low friction tremolo bearing and mechanically optimized inline sensor structure.

Abstract: This is a method and an apparatus that provides string bearings (32) and constant inter string pitch correction and pitch trajectory control tremolo device (64 or 80) for a stringed musical instrument (12). The string bearings (32) allow the strings (18) of the instrument to move freely in the axial direction and to be guided with high stiffness in the radial direction. The string bearings contain low axial friction and high radial stiffness bearing inserts (40) whose surface supports the strings to provide the witness points of nuts, bridges, frets, and finger boards. The material of preference for the string bearing inserts (40) is one of the highest energy resiliency and stiffness and the lowest friction. The string bearings and their inserts are adjustable (32, 56, 42, 58) or fixed position. Adjustments are in the horizontal, vertical, and axial (46, 50, 48) directions or any combination thereof. The constant inter string pitch correction and pitch trajectory control tremolo device (64 or 80 in FIG.

Abstract: Communication systems (101, 102) having dedicated communication resources are provided with receivers (111, 116) that monitor the communication resources (104, 108) of other communication systems. Communications between communication units in various systems are interchanged through appropriate interaction of the repeaters and the dedicated receivers so provided.

Abstract: A paging simulcast station remote control system decoder. The paging system decoder responds to signals generated in accordance with a predetermined signalling scheme comprising a series of tones and timed pauses. The decoder is also responsive to user programmable switches which provide station function tone and sector information. The paging system decoder then selectively deactivates a paging simulcast transmitter in response to signals received through a conventional paging communication link.

Abstract: A paging station remote control system capable of providing analog or binary modulation modes is described. Control of the paging base station is effected through a signalling scheme comprising a combination of tones and timed pauses generated in response to control signals supplied either manually or by a paging terminal. The paging system is capable of transitions between binary and analog modulation modes without first dekeying the paging transmitter.

Abstract: A paging simulcast station remote control system encoder is described. The paging system encoder generates signals in accordance with a predetermined signalling scheme comprising a series of tones and timed pauses and generated in response to control signals supplied either manually and or by a paging terminal. The paging system encoder provides control signals which instruct a paging transmitter to transmit a subsequent paging signal or to inhibit transmission until instructed to do otherwise. The paging encoder can generate signals to individually control as many as 30 individual simulcast transmission remote stations through an existing paging RF link.

Abstract: A simulcast paging transmitter remote control system capable of individual station control is described. The remote paging transmitter control system comprises an encoder and decoder which interface with a paging terminal and transmitter respectively. The system encoder and decoder communicate through a specifically formatted signalling scheme which is configured to provide station deactivation information as well as conventional paging information.

Abstract: A paging station remote control system encoder is described. The paging system encoder generates signals in accordance with a predetermined signalling scheme comprising a series of tones and timed pauses and generated in response to control signals supplied either manually or by a paging terminal. The paging system encoder provides control signals which instruct a paging transmitter station to key in the analog or binary modulation mode or to switch from one mode to another without first dekeying the paging transmitter.
