Abstract: A tiltable telescoping support structure positioning system includes a frame having first and second opposed vertical sections. A telescoping support structure is disposed between the first and second opposed vertical sections, the telescoping support structure having a plurality of telescoping sections extendable from a base section along a longitudinal axis thereof. The base section of the telescoping support structure is tiltably coupled to the first and second opposed vertical sections to permit the base section to tilt along a first tilt path towards either of the first and second opposed vertical sections of the frame. A tilting mechanism is coupled between the base section of the telescoping support structure so as to tilt the telescoping support structure about a second tilt path aligned perpendicular to the tilt path between the first and second opposed vertical sections of the frame.

Abstract: A multi-axial telescoping support structure positioning system includes a frame having first and second opposed vertical sections. An axle is rotatably coupled to the first vertical section of the frame. A first rotary actuator has a first end mounted to the second vertical section of the frame and a second end rotatable with respect to the first end attached to the axle to rotate the axle. A telescoping support structure has a plurality of telescoping sections extendable from a base section along a longitudinal axis. A second rotary actuator is attached to the base section of the telescoping support structure at an intermediate position along the length of the base section and to the axle at a position between the first and second vertical sections of the frame to tilt the telescoping support structure about a tilt axis aligned perpendicular to the longitudinal axis of the telescoping support structure.

Abstract: A multi-axial mast positioning system includes a frame having two opposed vertical sections, an axle coupled to the frame and rotatable around a first axis passing through the opposed vertical sections of the frame, and a mast coupled to the axle and rotatable about a second axis aligned with and perpendicular to the first axis. Level sensors measure the orientation of the mast along the first and second axes.

Abstract: In a new receiver design, the specific transmitter unit is unchanged from a prior patent application but may also be substantially as described in the prior art. The transmitter is initially activated by the input of the pseudo-random generator code. This code may be any alpha-numeric series, but must be identical to that input to the receiver. When the code is input through the keypad, the transmitter uses internal algorithms to generate a unique shift-register feedback combination. This creates a pseudo-random (PN) code which repeats after a programmable number of bits, depending upon desired maximal signal correlation time. That is the longer the code the longer the correlation time. This PN code sequence is clocked at the desired clock (CHIP) rate inside the transmitter unit. The PN code sequence which is thus generated is then added in phase to the data which is a substantially lower rate than the CHIP rate.

Abstract: Digital information is convolved with a pseudorandom code and then transmitted at radio frequency in a spread spectrum signal to a receiver also containing the same pseudorandom code. Since the transmitted signal is below the noise floor for that bandwidth, it is virtually unjammable and undetectable without possession of the pseudorandom code. Successful extraction of the transmitted information depends upon precise matching of the transmitted frequency and the exact phase matching of the pseudorandom code at the receiver with the convolved pseudorandom code in the transmitted signal.

Abstract: An audio squelch control for transceiver stations in which all transceivers are initially in a Call mode with the squelch control turned on. While in the Call mode, the squelch control is turned off, enabling the speaker, by receiving the station's coded address, plus a flag bit that is set, from a transmitting station. In addition to having the squelch circuit turned off, the receiving station is changed from the Call mode to an Auto mode. When in the Auto mode, the squelch control is turned off by receiving the station's coded address with the flag bit turned off. The squelch control of a station in one mode does not respond to a station in the opposite mode even if it receives its own coded address.
