20140243995 | STACKED PLANAR SHEET TISSUE ENGINEERING SCAFFOLDS WITH 3D STRUCTURAL ORDER - A three-dimensional tissue engineering scaffold device and related methods are disclosed herein. The tissue engineering scaffold includes a plurality of polymers sheets. Each polymer sheet includes a plurality of micro-scale pores defined through the polymer sheet. The polymer sheets of the tissue engineering scaffold are aligned and stacked such that some of the pores of neighboring sheets are offset along at least one axis of the pores. The offset pores create features within the tissue engineering scaffold. In some implementations, the tissue engineering scaffold device is seeded with cells. In certain implementations, the tissue engineering scaffold is either implanted into a patient or used to grow functional tissue ex vivo. | 08-28-2014 |
20140212964 | MODULAR PLATFORM FOR MULTI-TISSUE INTEGRATED CELL CULTURE - The systems and methods disclosed herein are generally related to a cell culture system. More particularly, the systems and methods enable the culturing and interconnecting of a plurality of tissue types in a biomimetic environment. By culturing organ specific tissue types within a biomimetic environment and interconnecting each of the organ systems in a physiologically meaningful way, experiments can be conducted on in vitro cells that substantially mimic the responses of in vivo cell populations. In some implementations, the organ systems are fluidically connected with a constant-volume pump. | 07-31-2014 |

A dye layer is coupled to the substrate, the dye layer having a peak absorption wavelength outside the visible band, the dye layer being configured to re-emit light at a peak emission wavelength outside the visible band, at least a portion of the re-emitted light being waveguided to the edge surface of the substrate. A photovoltaic device is coupled to the edge surface of the transparent substrate, the photovoltaic device being configured to absorb light at the peak emission wavelength and generate electrical energy. | 12-19-2013 |
20130103216 | METHODS AND APPARATUS FOR ENERGY DEMAND MANAGEMENT - To manage energy demands of a plurality of appliances, a meter controller apparatus receives a first message from a first appliance controller apparatus coupled to a first appliance of the plurality of appliances. The first message comprises first information regarding a first power demand of the first appliance and a first demand category associated with the first appliance, wherein the first demand category is one of a plurality of demand categories. The meter controller apparatus computes an updated meter controller model for the plurality of appliances based at least in part on the first message received from the first appliance controller apparatus and a present meter controller model for the plurality of appliances. | 04-25-2013 |
20120177696 | Diffusion-controlled dosage form and method of fabrication including three dimensional printing - The invention includes a core-and-shell dosage form or unit in which the core contains API and in which the shell substantially governs the release such as by controlling diffusion of API through the shell. The shell may comprise a release-blocking polymer, and particles of a release-regulating polymer. The shell may be substantially impervious but the release-regulating polymer may become suitable to allow diffusion through it when activated. The core may include a buffer region between the shell and the API-containing portion of the core. The dosage form may include multiple units. The dosage form of the invention is capable of providing a release profile whose time scale can be adjusted by adjusting powder composition, and which may be approximately zero-order release. The invention further includes methods of manufacturing such a dosage form, such as three-dimensional printing. | 07-12-2012 |
