  • Patent number: 8277974
    Abstract: Combinations of materials are described in which high energy density active materials for negative electrodes of lithium ion batteries. In general, metal alloy/intermetallic compositions can provide the high energy density. These materials can have moderate volume changes upon cycling in a lithium ion battery. The volume changes can be accommodated with less degradation upon cycling through the combination with highly porous electrically conductive materials, such as highly porous carbon and/or foamed current collectors. Whether or not combined with a highly porous electrically conductive material, metal alloy/intermetallic compositions with an average particle size of no more than a micron can be advantageously used in the negative electrodes to improve cycling properties.

  • Patent number: 8280218
    Abstract: A tilting mirror MEMS variable optical attenuator attenuates light over a band of wavelengths with minimum wavelength dependent loss. The attenuator includes a lens that has a wedged input face and is made from a material that has high dispersion. The lens design causes different wavelengths to travel different paths through the attenuator such that wavelength dependent loss is reduced. The attenuator may be designed to have minimum wavelength dependent loss at a specified attenuation greater than zero.

  • Patent number: 8211053
    Abstract: There are many medical situations that require removal of fluid from a patient. There are many ways to remove the fluid but many of these situations have not been solved. Herein, inventions are disclosed that generate osmotic pressure that can be used to remove these fluids very effectively, a technique which requires no harsh suction or pumping. One embodiment involves implanting a reservoir that has a semipermeable membrane sidewall. The reservoir contains trapped osmotic solutes that can not pass out through the membrane. But fluid from the patient can flow in. The osmotic pressure from the trapped solutes in the reservoir draws fluid from the patient across the semipermeable membrane and into the device. In some versions, the membrane can be changed as desired during the lifetime of the device by pulling the membrane out through the implanted device and putting a new one back in.

  • Patent number: 8206412
    Abstract: Various devices are described to provide filtering of flow from the aorta to the left carotid artery and the right carotid artery. The filters can be brought into a desired position through one or more peripheral arteries. A single filter device can provide the desired filtering or a plurality of devices can be used. In particular a single filter device can span between the brachiocephalic artery and the left carotid artery. These filter devices can be used effectively to capture emboli generated during procedures on the heart so that emboli do not travel to the patient's brain where the emboli can cause a stroke or other adverse event. In particular, these filters can be used during percutaneous procedures on the heart, such as endovascular heart valve replacement.

  • Patent number: 8187752
    Abstract: Lithium ion secondary batteries are described that have high total energy, energy density and specific discharge capacity upon cycling at room temperature and at a moderate discharge rate. The improved batteries are based on high loading of positive electrode materials with high energy capacity. This capability is accomplished through the development of positive electrode active materials with very high specific energy capacity that can be loaded at high density into electrodes without sacrificing performance. The high loading of the positive electrode materials in the batteries are facilitated through using a polymer binder that has an average molecular weight higher than 800,000 atomic mass unit.
