Title: Electric vehicle with variable efficiency regenerative braking depending upon battery charge state
Inventor: LYONS ARTHUR PAULL
IPC: B60L50/15
Filed: 1999-01-27
Granted: 2001-12-21
Abstract: An electric vehicle is controlled to conform its operation to that of a conventional internal-combustion-engine powered vehicle. In some embodiments, the charging of the batteries by the auxiliary source of electricity and from dynamic braking is ramped in magnitude when the batteries lie in a state of charge between partial charge and full charge, with the magnitude of the charging being related to the relative state of charge of the battery. The deficiency between traction motor demand and the energy available from the auxiliary electrical source is provided form the batteries in an amount which depend upon the state of the batteries, so that the full amount of the deficiency is provided when the batteries are near full charge, and little or no energy is provided by the batteries when they are near a discharged condition. At charge states of the batteries between near-full-charge and near-full-discharge, the batteries supply an amount of energy which depends monotonically upon the charge state. Charging of the batteries from the auxiliary source is reduced during dynamic braking when the batteries are near full charge. Control of the amount of energy returned during dynamic braking may be performed by control of the transducing efficiency of the traction motor operated as a generator.

The effect of this invention is that system capacity can be assured because the dispersed charging among modules can be decreased. In addition, the dispersion of charging can be eliminated to decrease the situation of lowering the battery module lifetime such that the reliability is increased.

Title: Streaming system for a close watershed
Inventor: INADA TAICHI
IPC: E02B15/00
Filed: 1999-03-26
Granted: 2000-07-01
Abstract: This is a streaming system for a close watershed with a unidirectional gate device for separating the water of the close watershed and the external watershed. The external watershed opens in a single direction to allow water flowing from the close watershed to external watershed. A feeding water pipe path from the external watershed to the inner end of the close watershed has a valve for allowing water to flow into the close watershed only. Water will not flow from the close watershed via the feeding pipe path into the external watersheds. The unidirectional gate device blocks the water during high tide; therefore, the water in the external watershed can only flow from the feeding pipe path to the inner end of the close watershed. During ebb tide, the water pressure is larger than that in the external watershed. Therefore, it pushes away the unidirectional gate. Since the feeding water path has a valve, the water in the close watershed cannot flow back from the feeding water path. A current and discharge is formed to the exterior in a single direction to cope with the morning and evening tides.

Granted: 2001-06-16
Abstract: An integrated circuit telephone line protection module (10) that provides both overcurrent and overvoltage protection to a telephone line (12). A preferred embodiment of the module (10) contains a pair of bidirectional current carrying devices (60, 80). A shunt resistance (74, 94) is formed in series with each telephone line conductor (16, 18) so that when an overcurrent condition exists on one or both of the telephone line conductors, the respective bidirectional devices (60, 80) are driven into conduction, thereby short circuiting the excessive current to ground. Independent of the overcurrent protection functions, each bidirectional device (60, 80) is also responsive to an overvoltage condition on the telephone line (12) to thereby clamp or crowbar the overvoltage to ground.
