  • Patent number: 12246599
    Abstract: A hydraulic regenerative braking system is provided for using hydraulic fluid to capture energy from a vehicle during a braking event. The system captures kinetic energy from a shaft of the vehicle and stores the kinetic energy as hydraulic potential energy. That is, the system captures rotational energy as hydraulic potential energy in an accumulator. The hydraulic regenerative braking system also discharges the hydraulic potential energy as kinetic energy. During braking, kinetic energy is transferred from the vehicle shaft to a gearbox, and from the gearbox to a hydraulic pump. The hydraulic pump uses the kinetic energy to pump hydraulic fluid to an accumulator, increasing the hydraulic potential energy stored in the accumulator. During driving, the hydraulic fluid is released from the accumulator to the hydraulic pump, generating kinetic energy that is transferred to the vehicle shaft via the gearbox.

  • Patent number: 9352743
    Abstract: A hydraulic hybrid system for implementation in a machine. The system includes a hydraulic system, an energy source, an output, and a transmission. The hydraulic system includes a primary hydraulic pump/motor (primary motor) that is hydraulically coupled to a reservoir and a variable-volume accumulator assembly. The primary motor is configured to charge an accumulator of the variable-volume accumulator assembly with a working fluid when mechanically driven. The storage volume of variable-volume accumulator assembly varies based on a kinetic output condition of the machine. The energy source is configured to produce primary kinetic energy. The output is configured to receive at least a first portion of the primary kinetic energy. The transmission is coupled between the energy source and the output and selectively coupled to the primary motor. The transmission is configured to mechanically drive the primary motor using a second portion of the primary kinetic energy.

  • Patent number: 8003179
    Abstract: Film structures, packages, films and methods of making the same are provided wherein the film structures have a desiccant material incorporated into at least one layer of the film structures and further wherein the film structures can comprise a material for making a peelable seal when the film structures are heat sealed to other film structures. The film structures are utilized for a package to hold a product that may be sensitive to the presence of moisture. The product may preferably be pharmaceutical products, nutraceutical products, or devices such as absorbable sutures or medical stents, although any moisture-sensitive product is contemplated by the present invention.

  • Publication number: 20080009642
    Abstract: A probucol or a probucol derivative can be efficiently converted to a monoester or monoether of probucol by reacting the free hydroxyl-containing probucol or a derivative thereof (by which is meant a probucol compound with at least one substituent that is different from that on the parent probucol molecule but which maintains the two free hydroxyl groups) with a Grignard reagent or a lithium reagent that produces a magnesium bromide or lithium salt of probucol or the probucol derivative. The probucol compound anion anion is then reacted with an ester or ether forming compound.
