Abstract: The present invention relates to a suspended ceiling hanger clip and a suspended ceiling formed using the hanger clip. The suspended ceiling hanger clip has a longitudinally extending base having a first end and a second end and a pair of generally parallel co-extensive flanges extending downwardly from the base. At least one projection in each flange is formed with a ramp surface. An aperture is formed in the base for receiving an upper end of the elongate suspension rod therein. The suspension rod has a longitudinal axis extending along a length between spaced apart upper and lower ends, with the lower end having an attachment means. The upper end of the suspension rod extends through and is fixedly retained from removal from the aperture in the base of the hanger clip.

Abstract: The invention provides a photonic package system comprising at least two optical alignment pins integrated on a package substrate. A key feature of this invention is the addition of alignment structures within the package. When combined with the use of micro optics it enables a ‘fiber-less’ photonic package system that requires no physical connection between and optical fiber and the photonic package system.

Abstract: There is provided a device for measuring a user's oxygen-consumption. The device includes a venturi tube.

Abstract: The present invention relates in general to a suspended ceiling clip and method of using the clip to support a grid-work of channels in a key lock concealed grid suspended ceiling system. The suspended ceiling clip is used for mounting a furring channel to a top cross rail. The clip comprising a longitudinally extending base; a pair of flanges extending downwardly from the base and between which the base is located; a pair of hooks on each flange, each pair of hooks adapted to releasably connect to the furring channel; at least one projection in each flange, each projection engaging with a surface on the top cross rail to secure the clip within a longitudinal slot of the top cross rail; and wherein the air of flanges extend a predetermined distance from the base so as to space apart the top cross rail and the furring channel to provide a void therebetween.

Abstract: Embodiments of pumps are described herein that may be used as peristaltic pumps. The pumps may include features that provide for quiet operation as well as automatically loading of tubing. Embodiments may be implemented in blood separation systems.

Abstract: A system and method for detecting a pre-charge pressure of a hydraulic braking system are disclosed. A controller receives pressure readings from a pressure sensor indicative of the pressure of a hydraulic brake accumulator or the lower pressure of more than one accumulator. In response to fluid being provided to the hydraulic accumulator, the controller determines a first rate of pressure change, a second rate of pressure change different than the first rate, and a transition pressure between the first and second rates. The controller determines an approximate pre-charge pressure of the hydraulic brake accumulator based on the transition pressure. A warning can be provided to the operator or another when the determined pre-charge pressure is lower than a reference pressure.

Abstract: A method of controlling the temperature of a brake arrangement for a machine is disclosed. The method includes providing a flow of pressurized fluid to the brake arrangement and sensing a first temperature of the fluid downstream of the brake arrangement. The method also includes determining a first temperature range for the brake arrangement and determining if the first sensed temperature falls in the first temperature range. The method also includes requesting an adjustment of at least one fluid parameter of the flow of pressurized fluid in response to determining that the first sensed temperature does not fall within the first temperature range such that the sensed temperature moves to the first temperature range.

Abstract: According to the invention there is provided a tertiary effluent treatment process for reducing the phosphate levels in effluent. The process comprises the steps of delivering effluent from a wastewater treatment plant to a primary filter, delivering the filtered effluent to a series of two or more phosphate removal filters, delivering the filtered phosphate-depleted effluent to a treated water tank as treated water, delivering the filtered phosphate-depleted effluent from the treated water tank to a discharge tank as treated water; and, discharging the treated water from the discharge tank as required. Each phosphate removal filter comprises a plurality of polymer-based beads having nano-particles of iron oxide coated thereon. The advantage of using a series of two or more phosphate removal filters is that the process can deliver a final effluent containing specific pre-determined levels of phosphate that may be as low as 0.01 mg/L of effluent, but will in all cases be below 1 mg/L.
