Granted: 2000-02-01
Abstract: A secondary power system eliminates the need for an automatic transfer switch and permits simultaneous supply from different sources.  Primary power is rectified and connected to a DC bus, an AC generator has its output rectified and connected to the DC bus,  and a storage battery is also connected to the DC bus.  Current on the DC bus is inverted to AC to provide an uninterrupted power supply.  The system is connected to a household electrical system by a power distribution panel which can be installed in a home prior to the secondary power system and can facilitate installation of the secondary system.  The distribution panel can selectively bypass the secondary system and can disconnect non-vital loads when primary power is not available.  The generator is powered by an engine using gasoline, natural gas or water, which can also power other systems, such as air conditioning, with exhaust heat or rotary motion.

Filed: 1996-08-30
Granted: 2003-01-21
Abstract: A telecommunications system having at least one base unit and a plurality of portable units is arranged to enable automatic re-registration of a portable unit with the system. The portable unit includes system and unit identity detectors and a registration sequence generator.     The registration sequence generator is connected to a timer which monitors the elapse of time since a signal from a base unit of the system intended for the portable unit is received. The registration sequence generator generates a re-registration request in the event the monitored elapse of time is greater than a predetermined period and a signal from a base unit of the system is received which is not intended for the portable unit. With the system described portable units can automatically re-register with the system after being out of range of a base unit without the need for a separate beacon signal.

Abstract: The solar tracking system maintains a solar collector with its responsive surface normal to the sun rays.  It includes a shaft supported for rotation about an axis parallel to the north-south axis of the earth, a stepper motor for intermittent rotation of the shaft at a mean rate equal to the earth's rate of rotation.  A solar collector securing assembly is located on one side of the shaft and includes a bracket, collars securing the bracket to the shaft, a support for fixing a solar collector pivoted to the bracket about a pivotal axis transverse to the shaft to vary the inclination of the support relative to the shaft and stays between the support and the bracket  to maintain  the  support  at  an adjusted inclination.  A counter-balancing system includes an arm secured to the shaft and extending normal thereto and away from the assembly and a weight adjustably mounted on the shaft. This system counter-balances the assembly and a solar collector fixed thereto irrespective of the rotational  position  of  the  assembly  about  the  shaft  and  the inclination of the support relative to the shaft. Preferably, two solar collectors are mounted on the shaft, one being an array of solar cells feeding a battery which in turn feeds a stepper motor driving the shaft through a step down gear box. The sun shadow of a pointer normal to the solar collector panel serves to properly align the panel. Alternately, the current generated by the solar cells is measured and its maximum indicates that the solar panel is properly aligned with the sun.

Abstract: The process of the present invention enables a mobile radiotelephone to operate at a 100% duty cycle while providing closed loop power control. The base station measures the signal to noise ratio of the signal from the mobile and compares (305) that SNR with the SNR threshold values the base station has for each data rate the mobile is capable of transmitting. The base station then generates power control commands (310) to instruct the mobile to change its power depending on the outcome of the comparisons.
