Abstract: A vehicular power system for powering a parallel hybrid vehicle having an internal combustion engine, electric motor/generator, ESD source, and an inverter includes a set of demand parameters for controlling the amount of flow of current between the ESD source and the electric motor/generator. The demand parameters are utilized by the inverter for controlling this current. A set of limiting parameters which indicate that the application of full demand would jeopardize the operational environment or is unwarranted by utilizing the limit of full demand. The demand parameters control the amount of current to the electric motor/generator from the ESD during an electric motor/generator assist mode and from the electric motor/generator to the ESD when the battery is acting as a generator for recharging the ESD. Additionally, a plurality of demand parameters may exist providing options for manipulating the control of the electric motor/generator depending upon the operating environment of the vehicle.

Abstract: A diltiazem pellet formulation for oral administration comprises a core of diltiazem or a pharmaceutically acceptable salt thereof in association with an organic acid, and a multi-layer membrane surrounding the core and containing a major proportion of a pharmaceutically acceptable film-forming, water insoluble synthetic polymer and a minor proportion of a pharmaceutically acceptable film-forming, water soluble synthetic polymer. The number of layers in the membrane and the ratio of the water soluble to water insoluble polymer being effective to permit release of the diltiazem from the pellet at a rate allowing controlled absorption thereof over a twenty four hour period following oral administration.
