Abstract: An inter-zone aerobic to anoxic zone flow rate control system for single vessel multi-zone bioreactor plants for wastewater treatment is described herein. The system of the invention provides control of the relative treatment times of the mixed liquor in the horizontally disposed and adjacent aerobic and anoxic treatment zones of the bioreactor by providing one or more flow rate adjusting gates located between the aerobic and anoxic zones of the bioreactor. The opening of the gates is adjustable in accordance with sensed conditions in the treatment zones. An automated embodiment of the invention includes a programmable logic controller that provides control scripts for adjusting the opening of one or more flow control gates according to inputs from sensors and per programmed instructions. An automated and supervised embodiment of the invention includes a computer interfaced with a programmable automating controller.

Abstract: A new add-on vehicular system is capable of responding to large area or nation-wide commands over paging networks, to remotely foil the unauthorized use or theft of a vehicle or a fleet automobile or a group of fleet vehicles, as well as to help the recovery of stolen vehicles. The preferred embodiment of the system comprises a paging receiver and decoder, a microcontroller with embedded programmable software and memory and a vehicular systems control interface. The system does not require central monitoring systems, or portable controls or vehicular user set controls or portable key chain controls or keypads or cellular phones or separation of vehicular transceivers from owner carried transceivers to activate the system. In a second embodiment, a two-way radio paging approach is employed in the system to expand its capabilities and to additionally provide remotely controlled transmission of data from vehicles, including data pertaining to the position coordinates of the vehicle.

Abstract: The invention pertains to a method for diagnosing oncological diseases wherein an effective small amount of blood is obtained, such as from a finger, and a solution containing blood plasma or serum is exposed to laser radiation and the values of one or more parameters are determined upon measurements at molecular level. Said parameters are then compared with analogous measured or established parameters of a reference solution to determine whether there are significant variations or similarities which indicate the absence or presence of oncological diseases or a predisposition to same. In a preferred embodiment of the invention, blood plasma or serum is diluted in water up to 25% of the volume and the solution is then exposed to laser radiation in the standard mode.

Abstract: A Computerized Mobile Two-Way Radio System is provided having microprocessor enhanced capabilities and versatility for wide area/multiple region two-way radio networks with multiple categories of users and adaptability to multiple international standards and mobile radio equipment configurations. The main elements of the system consist of (1) a microprocessor-based Control Unit, (2) a Digital Serial Interface/Link and (3) a microprocessor-based Convertible Transceiver Unit. The Control Unit provides many facilities and capabilities for the operator and the system in compact form. The Interface/Link provides a two-way path for serial data consisting of digitized audio and digital command and status signals. The Transceiver Unit is designed for operation and control over the Digital Serial Interface/Link.

Abstract: A digital serial interface system is provided for communicating digital signals including digitized audio between microprocessor-based Control and Transceiver Units of two-way radio communications equipment. The system of the invention essentially comprises three subsystems: (1) an interface in the microprocessor-based Control Unit, (2) an interface in the microprocessor-based Transceiver Unit and (3) a two-way medium for linking the two units. Various signals and audio in the Control Unit interact with a software-driven microprocessor of the Control Unit and are digitized and then translated into a serial format, organized in channel groups through a TDM (Time Division Multiplex)/PCM (Pulse Code Modulation) process and transmitted in frames through a two-way medium to the Transceiver Unit which is also microprocessor-based and incorporates a similar interface. The digital data communicated to the Transceiver Unit then undergoes a reverse process. The Interface System is duplex (bidirectional).

Abstract: A method for scrambling speech such as in a mobile land based communication system is disclosed. Essentially, variable length time samples of digitized speech are stored and time inversion scrambled. The scrambled speech is converted back to analog form and transmitted to a receiver which reciprocates the process to reproduce the desired speech signals. Scrambling and descrambling of the speech signal is synchronized to provide corresponding sample time inversions and accurate reproduction of the speech input signal. The level of security afforded by the scrambling method may be varied by varying the length of the sampling period or by mixing forward and reverse time samples under control of an algorithm.

Abstract: A control system for microprocessor and software enhanced land mobile radio communications systems is provided to increase versatility, capabilities and facilities while providing an easier and more precise control of various radio protocols. As the usage of microprocessors and software is increased in radio communications equipment, additional capabilities, digital protocols and versatility can be desired in such equipment. However, this requires additional and special controls and prior art approaches have limitations with respect to capacity, versatility, size and compatibility with digital protocols. The innovative approach of the invention provides a compact new system to replace prior art multipositional knobs and switches and refines the system of control. The novel control system provides for an efficient utilization of space while achieving outstanding versatility and new operational and control capabilities.

Abstract: A new power system employs aluminum as a primary fuel resulting in a total energy/volume ratio several times more favorable than gasoline. The system includes a fuel store, a reactor which may be the same mechanical element as the store and means to utilize the released energy. Illustratively, aluminum may be reacted with steam to form aluminum oxide with the release of large quantities of usable energy. After the reaction, the aluminum oxide may be reconverted to aluminum.
