A system that rapidly detects the presence of a target analyte in a biological test sample, which includes a sensor for measuring a detectable signal generated upon the reaction of a biosensor reagent with a specific target analyte within the sample; a reservoir card that includes the biosensor reagent that further includes living, engineered biological cells, and wherein the reservoir card is configured to interface with a test cartridge base; a test cartridge base configured to accept the reservoir card and to be placed within the testing device, wherein the test cartridge base further includes a reaction chamber adapted to receive both the biosensor reagent and the sample and a fluid displacement mechanism that includes a dispensing plunger, wherein actuation of the dispensing plunger displaces the biosensor reagent in the reservoir into the reaction chamber where the biosensor reagent is mixed with the sample; and a function verification cartridge adapted to be received and recognized by the testing device, and that is operative to confirm the proper functioning of the plunger and the sensor.

A belay device may include a front plate with a first lobe and a back plate with a second lobe. The belay device may be engageable and disengageable such that the first lobe is separated from the second lobe at a first distance and a second distance, respectively. The belay device may maintain ability to operate when the belay device is disengaged. The belay device may include a handle and cam pin that cooperate to create a mechanical advantage for controlling separation distance between the first and second lobe. The handle may prevent rotation in a first direction via a lockout protrusion. The handle may prevent rotation in a second direction via a handle stop and/or a retaining rib. The belay device may include an ergonomic feature to accommodate a user's hand placement and/or shroud rotation of the front plate.

A drum for storage or transportation of a coil, comprises a base configured to rest on a horizontal surface. A hollow polygonal core extends upward from the top of the base. A cover also extends from the top of the base and has a circular, cylindrical, inner wall. The cover is spaced from the core, forming an annular space for receiving a coil. The core is composed of a plurality of planar parts hinged to one another so that the core can be collapsed and stored or shipped in a substantially flat condition, and expanded to its polygonal shape for connection to the base. The cover is composed of two or more arc-shaped parts, which are capable of being nested for storage and shipment. The drum can be used for storage or transportation of dry bulk material, in which case the core can be eliminated.

Test cartridge

System for rapid analysis of biological samples

A test cartridge for use in sample analysis is provided. The test cartridge includes a reservoir card that further includes a reagent that includes living biological cells; and a test cartridge base configured to accept the reservoir card. The reservoir card is configured to interface with a test cartridge base through at least one fluid port. The test cartridge base includes an elliptical reaction chamber having a central axis and an inlet channel connected to the reaction chamber. The inlet channel is positioned above the reaction chamber at an angle of 15-60 degrees above the horizontal and is offset from the central axis of the reaction chamber. Upon introducing a sample to be analyzed into the test cartridge base through the inlet channel, the sample is homogeneously mixed with the reagent while minimizing damage to the living biological cells.

A portable system for real time detection of the presence of an infectious agent in a biological sample employs a reagent which detects the presence of a specific infectious agent in the sample, and emits a detectable signal when the reagent reacts with the sample and detects the presence of the infectious agent. A test cartridge has a reaction chamber for receiving the sample and the reagent. The reaction chamber has a predetermined internal geometry and at least one inner surface. Introducing the sample and the reagent into the test cartridge mixes the sample and the reagent. A testing unit receives the test cartridge, and includes a sensor for detecting an emitted detectable signal. The detection of the emitted detectable signal is indicative of the presence of the infectious agent in the sample.

A reel comprises a cylindrical core composed of two complementary arcuate core segments, a pair of flanges disposed respectively at axially spaced opposite ends of the core, and a pair of rings for connecting the core to the flanges. The rings are fixed respectively to facing inner sides of the flanges. Cooperating slots and tongues on the rings and core elements prevent the flanges from moving relative to the core in the direction of the axis of the core. The tongues enter the slots when the core segments are brought together. Resiliently bendable locking arms protrude radially inward from both ends of each core segment, and each locking arm is engageable by a snap fit with one of the rings when the core segments are brought together. Access openings in the flanges adjacent each of the locking arms allow access to the locking arms for disengagement from the rings.

A control device, such as a wireless remote control for a load control system, comprises a return spring that operates to return multiple buttons to respective idle positions resulting in lower cost and complexity of the remote control. Specifically, the remote control comprises a first button having an edge, and a second button having a flange positioned adjacent the edge of the first button, such that the edge of the first button rests on the flange of the second button. The return spring has a first end fixed in location with respect to the housing and a second end contacting the second button for returning to the second button to an idle position after an actuation of the second button. After an actuation of the first button, the return spring causes the flange of the second button to force the first button back to an idle position.

A spa cover lifter for moving a spa cover from a closed position to a storage position includes a drive mechanism, a fixed base and a lifting arm assembly. The lifting arm assembly is mounted to first or second leaves of the spa cover. The lifting arm assembly is driven by the drive mechanism and is moveably mounted to the fixed base. The lifting arm assembly includes a cover pivoting assembly and a cover transporting assembly. The cover pivoting assembly is driven by the drive mechanism to move the cover from the closed position to an intermediate position and the cover transporting assembly is driven by the drive mechanism to the move the cover from the intermediate position to the storage position. The spa cover lifter has an automatic shutoff for cutting power when an obstacle is encountered. A method of moving the spa cover is also disclosed.
