Abstract: A fluid monitoring system has a plurality of sensors, the sensors being acoustically coupled to a pipe system containing interconnected fluid-transporting pipes. The sensors collect sensor data that is analyzed by an analysis system to provide leak identification on the pipe system. Each sensor in the plurality of sensors is configured to be programmed adaptively by the analysis system to improve system performance parameters. A method for analyzing fluid flow is also described in which data from a plurality of acoustic sensing devices is analyzed using learning algorithms.

Abstract: A first income need is determined to meet essential expenses for a user during retirement, and a second income need is determined to meet discretionary expenses for the user during retirement. A default target income mix is calculated to meet the first income need and the second income need. The default target income mix is a set of weights of one or more classes of income generating products. Qualitative investment preferences are quantified for the user. The default target income mix is adjusted using the quantification of the qualitative investment preferences to form an adjusted target income mix including a second set of weights of the one or more classes of income generating products.

Abstract: A target income mix is expressed as a set of weights in a portfolio of one or more classes of income generating financial products to meet a first income need indicative of essential expenses and a second income need indicative of discretionary expenses for a user. The target income mix is converted to dollar amounts to invest in the classes of income generating products to meet the first and second income needs. Using the target income mix percentage weights, initial purchase amounts are determined from the user's available assets. The initial purchase amounts for each of the classes of income generating products can be adjusted until the overall portfolio is projected to produce enough after-tax income to meet the first income need at a first predetermined confidence level or return assumption and meet the first income need and the second income need at a second predetermined confidence level.

Abstract: In one aspect of the present invention, a solar receiver with an improved heat sink design will be described. The solar receiver includes a photovoltaic cell and a heat spreader plate having a frontside and an opposing backside. The photovoltaic cell is positioned on the frontside of the heat spreader plate. Multiple front and rear heat sink fins are attached to and extend out of the frontside and the backside of the heat spreader plate, respectively. In various implementations, the front heat sink fins are positioned adjacent to, above and below the photovoltaic cell.

Abstract: Disclosed are both a housing and an assembly for a tunable external cavity laser. The housing includes: a base section, a motion section, and an actuator. The base section includes a proximal and distal portion, and the laser and the dispersive element mounted at respectively the proximal and distal portions such that energy emanating from the laser strikes the dispersive element leaving the dispersive element as a second beam at an angle with respect to the first beam which depends on wavelength. The motion section includes a proximal and a distal portion and a torsional member positioned at the proximal portion and the reflector positioned at the distal portion to reflect the second beam to the laser via the dispersive element, and the motion section supported by the base about the torsional member.

Abstract: A compound semiconductor that is suitably doped to exhibit the DX effect is irradiated with an optical beam of spatially varying intensity whereby localized regions of persistently higher conductivity and lower refractive index are created in the semiconductor where sufficient intensity of the beam was incident. The persistently higher conductive region can be used to bridge selected gaps in conductive paths on a support member use in memory device and the regions of lower refractive index can be used to providing guiding in a wave guide, to form high resolution gratings, or to form holograms.

Abstract: A phase conjugate mirror is formed of a compound semiconductor doped with DX centers, such as silicon doped gallium-arsenide, through which are passed three light waves of the same wavelength but in different directions for non-linear four wave mixing. The phase conjugate mirror is used as one mirror of a confocal resonator housing a laser medium to form a laser and light from such laser is used to form the three waves of the same wavelength used to pump the phase conjugate mirror.
