Abstract: Methods and systems are provided for an on-board electrical system for a motor vehicle that includes one or more power sources and an electrical subsystem with a switch that can be actuated to selectively bypass a DC/DC converter and a storage device, responsive to electrical parameters such as the power demand of high-power consumers. In one example, when high-power consumers have low and constant power requirements, the switch may be positioned to bridge the DC/DC converter and storage device. Further, the method includes selectively controlling the power source in order to meet peak power demands with the power source operating at the greatest efficiency for the given operating conditions.

Abstract: An on-board electrical system for motor vehicles has a battery, a generator and at least one normal consumer that is connected to the battery in a switchable manner. A DC voltage/DC voltage converter is connected on its primary side to the battery and on its secondary side to a high-load resistor. A switch connects the high-load consumer to a storage device in a first switching position, and to the primary side in a second switching position. A controller controls and operates the switch between the first and the second switching position. A device that detects the actual electrical power of the high-load consumer is associated with the high-load consumer, and is connected at the output end to the controller.

Abstract: A system and method for charging a vehicle having a first battery, such as a high-voltage traction battery, and a second battery, such as a low-voltage battery, include controlling a DC converter or relay to effectively decouple the second battery from the converter when the vehicle is connected to an external power source to reduce or prevent damage to the second battery from extended or prolonged charging. The second battery may be effectively decoupled from the converter by controlling the relay or converter voltage based on state of charge of the second battery so that substantially zero current flows to and from the second battery relative to the converter and any vehicle low voltage consumers/accessories.

Abstract: Absorbable stents and absorbable stent coatings have been developed with improved properties. These devices preferably comprise biocompatible copolymers or homopolymers of 4-hydroxybutyrate, and optionally poly-L-lactic acid and other absorbable polymers and additives. Compositions of these materials can be used to make absorbable stents that provide advantageous radial strengths, resistance to recoil and creep, can be plastically expanded on a balloon catheter, and can be deployed rapidly in vivo. Stent coatings derived from these materials provide biocompatible, uniform coatings that are ductile, and can be expanded without the coating cracking and/or delaminating and can be used as a coating matrix for drug incorporation.

Abstract: The invention relates to an ocular implant for treating glaucoma. The problem addressed by the invention is to make it possible to drain aqueous humor from the anterior chamber of the eye into the subconjunctival or suprachoroidal space in order to lower the intraocular pressure in glaucoma cases. The device is to do away with the drawbacks of known valve mechanisms and should be economical to produce. In order to solve said problem, the glaucoma drainage implant is composed of an elongate, hollow main member in which a flow-limiting membrane is arranged in the inflow region.
