Title: Hydrophobic fumed silica
Inventor: TAKAMUKU ASTUSHI
IPC: C01B33/16
Filed: 2004-04-30
Abstract: A hydrophobic fumed silica which has been hydrophobized with a cyclic dimethylsiloxane, characterized by having a value of M, which indicates lipophilicity, in the range of 48 to 65, a tap bulk density of 80 to 130 g/L, excluding 80 g/L, and a value of n, which indicates dispersibility as measured in toluene, of 3.0 to 3.5. This hydrophobic fumed silica has a high bulk density although highly hydrophobic.

Title: Microfluidic systems for size based removal of red blood cells and platelets from blood
Inventor: TONER MEHMET
IPC: B01L99/00
Filed: 2004-06-09
Abstract: The invention features devices and methods for enriching a sample in one or more desired particles. An exemplary use of these devices and methods is for the enrichment of cells, e.g., white blood cells in a blood sample. In general, the methods of the invention employ a device that contains at least one sieve through which particles of a given size, shape, or deformability can pass. Devices of the invention have at least two outlets, and the sieve is placed such that a continuous flow of fluid can pass through the device without passing through the sieve. The devices also include a force generator for directing selected particles through the sieve. Such force generators employ, for example, diffusion, electrophoresis, dielectrophoresis, centrifugal force, or pressure-driven flow.
Patent CA-2535065-A1 (CA)
Inventor: LAMPROPOULOS GEORGE A
IPC: G01N21/27
Filed: 2006-01-24
Abstract: A software solution that increases the Signal to Noise Ratios (SNRs) of hyperspectral systems for a fixed spectral resolution is proposed. This technique solves the problem that sensors with higher spectral resolution suffer from poor SNR. The proposed technology includes an averaging process and a deconvolution process. For any given hyperspectral signature with high spectral resolution, a filter with wider band than the hyperspectral sensors is applied to get the convoluted signal to increase SNR. The trade-off is the reduction of the spectral resolution. A  proper deconvolution process will then be applied to the averaged signal to reconstruct the original signature. The final signal can has nearly restored high spectral resolution while maintaining the high SNR of the averaged signal. This technique could be implemented in the existing hyperspectral systems so that the user could achieve adequate SNR at any resolution independent of optical design. Based on this idea, new hyperspectral sensors could be designed with wide and overlapping bands to have both high spectral resolution and high SNR.

Title: Thermal break structural stud
Inventor: NUSZ DAVID
IPC: E04C2/296
Filed: 2006-02-28
Abstract: This invention is a structural building stud that provides interior cavity space for insulation. It also affords construction time savings for in-wall infrastructure systems such as wiring, plumbing, telephone, networking, etc.   The common building method is to use solid lumber studs which have the thermal characteristics of conducting thermal energy between the separated air spaces.  This invention breaks the conductivity of the two wall surfaces and also provides time savings during the construction period by affording the interior cavity space for in-wall infrastructure. Building corners and spaces behind partition ties are easily assessable for a complete insulation barrier.     This invention is comprised of two vertical upright pieces separated by additional spacer blocks to maintain consistent cavity. These pieces are connected by gang-nail plates, nails, screws, glue or other fasteners or methods.     The interior cavity space between the two vertical upright pieces provides a thermal break for energy efficient construction. This space can be filled with insulation as well as providing room for in-wall wiring, plumbing, etc. The spacer blocks are also usable for attaching wiring to the studs.
