Abstract: The disclosed technology is generally directed to a lift. In one example of the technology, a lift comprises a chassis, a mounting base, a platform, a motor, a plurality of guardrails, and a counterweight. The mounting base is arranged to swivel relative to the chassis. The platform is coupled to the mounting base. The platform is arranged to slide horizontally relative to the mounting base. The motor is arranged to raise and lower the mounting base relative to the chassis. The plurality of guardrails is coupled to the platform. The counterweight is coupled to the chassis such that the counterweight prevents the lift from tipping over while the platform is extended relative to the mounting base.

Abstract: A chaotic communication system employs transmitting and receiving chaotic oscillating circuits. One improvement to first-generation systems is the ability to modulate a nonreactive element in the transmitting circuit, thus increasing modulation bandwidth. Other features include insertion of a gain control amplifier in a chaotic receiver; signal filtering in chaotic transmitters and receivers; use of chaotic modulation techniques for cellular telephony applications; dual-transmitter and receiver systems; a dual receiver synchronization detector; interfaces to communication systems; analog chaotic signal modulation; use of multiple chaotic transmitters and receivers; digital algorithm improvement using a cube-law nonlinear component; a Gb-only receiver; a Gb-only transmitter; and positive slope transmitter and receiver systems.
